Executive summary
This Engineering Report provides the technical background for a variation to the digital
channel plans (DCPs) for Remote and Regional Western Australia (RRWA) so as to:
� Allot channels for three commercial services at sites covered by the Commercial
Television Conversion Scheme to enable the delivery of the full suite of commercial
services.
� Minimise the number of services that will need to change channels in order to clear
the digital dividend spectrum.
� Allot channels following the “block” channel planning approach.
The current DCPs allot only one channel to commercial broadcasters, on which they will
multichannel their programs, and, as per previous DCP practices, allots channels across the
full UHF band (channels 28 to 69).
Following the announcement in 2010 of the extent of the digital dividend to be delivered
following the switchover of analog services, the ACMA initiated discussions with RRWA
broadcasters to consider a variation to the DCPs that would minimise the need for services to
be restacked to deliver the digital dividend.
On 9 November 2010, Senator the Hon Stephen Conroy, Minister for Broadband,
Communications and the Digital Economy (the Minister) announced additional funding for the
RRWA commercial broadcasters to deliver the full suite of commercial television services.
This requires the RRWA commercial broadcasters to revoke their election to multichannel
using one channel per site and a variation to the DCPs to allot three commercial television
channels at each site.
This engineering report has adopted a “block” planning approach and identified channels that
will allow new services to be implemented on channels that will not need to be restacked. This
will minimise the costs to broadcasters of restacking services and the disruption to viewers of
needing to retune after services are restacked. Section 4 of this report details the proposed
new channel plans.
There will be some consequential changes required to deliver the proposed variation. A
number of operating analog services will need to either change channels or close early to
allow the digital services to commence on their final channels. A number of operating national
digital services will also need to shift to new channels prior to the general restacking of other
operating digital services following switchover. These services are detailed in Section 5 of this
report.

1. Introduction
The current Commercial DCP for WA Part 2: Remote and Regional WA (RRWA DCPs) allots
only one channel to commercial broadcasters on which they have elected to multichannel
their programs. As per previous practices, the National and Commercial DCPs also allot
channels across the full UHF band (channels 28 to 69).
In June 2010, the Minister announced 2010 the size (126 MHz) and frequency band (694–820
MHz) of the UHF digital dividend. 1 In July 2010 the minister directed the ACMA on a range of
issues related to the replanning of digital television to yield the 126 MHz of digital dividend.
The Australian Communications and Media Authority (Realising the Digital Dividend) Direction
2010 (the Ministerial Direction) established high-level objectives for the ACMA‟s restack
planning, including:
� the requirement to clear the dividend band (694–820 MHz);
� the requirement to complete restack as soon as possible (with a target of end 2014) 2 ;
� the number of services to be planned at each location (generally six but nine in
licence overlap areas 3 ;
� the reservation of some VHF spectrum for the possible expansion of digital radio into
regional areas (14 MHz);
� the requirement to consolidate all metropolitan area services at main transmission
sites onto VHF.
Following these announcements the ACMA initiated discussions with broadcasters to
consider a variation to the DCPs for RRWA which would minimise the need for services to be
restacked to deliver the digital dividend. A draft engineering report (TPS Report 2010/12) was
prepared and circulated to broadcasters in August 2010 and a number of meetings were
arranged where options could be discussed.
The draft engineering report adopted a minimum moves planning approach while the
broadcasters proposed an alternative „block” planning approach. The draft engineering report
also attempted to minimise the impact on operating analog and digital services. The
commercial broadcasters proposed that most affected analog services could be closed early
or shifted to alternative channels. However, the details of which services would be affected
were not supplied as part of the proposal.
At a meeting on 6 December 2010, the ACMA and broadcasters discussed practical options
to allow the implementation of a block planning approach prior to the digital switchover in
2013.
On 28 February 2011, the ACMA released the discussion paper Clearing the digital dividend:
Planning objectives and principles for restacking digital television channels. The primary role
1 Media release: Senator the Hon Stephen Conroy, Minister for Broadband, Communications and the Digital
Economy, Size and Location of the Digital Dividend, 24 June 2010.
2 The minister‟s direction sets the policy objective that the digital dividend be cleared as soon as possible after the
final digital television switchover day. The explanatory statement to the direction elaborates that it is the
government‟s aim for the digital dividend spectrum to be cleared within 12 months of the switch-off of analog
television services on 31 December 2013 (i.e. the aim is for clearance by the end of 2014).
3 The minister‟s direction sets a policy objective so that over time in each metropolitan area the number of
channels made available does not exceed six. The explanatory statement to the direction elaborates that the
minister intends that the remaining spectrum support the provision of up to six channels nationwide.

of the discussion paper was to consult on a proposed set of planning principles that would
enable restack channel plans to be developed in order to clear the digital dividend. In the
discussion paper, the ACMA proposed a set of restack objectives, stated its preliminary view
that a block planning approach should be adopted and proposed a set of detailed restack
planning principles. On 26 May 2011, the ACMA announced that a block planning approach
should be adopted and published planning principles for restacking digital television services.
In most parts of Australia this will require a fairly extensive restacking of currently operating
digital television services. Such changes will require broadcasters to undertake a logistically
complex retuning process and affected viewers will need to rescan receivers. Both of these
activities are likely to entail costs to the broadcast industry and potentially some disruption, for
viewers.
On 9 November 2010, the Minister announced additional funding for the RRWA commercial
broadcasters to deliver the full suite of commercial television services. This requires the
RRWA commercial broadcasters to revoke their multichannelling election and a variation to
the DCPs to allot three commercial television channels.
This engineering report details the channel plan that has been developed in discussions with
the RRWA broadcasters and government. It has adopted the block approach and generally
allotted channels that will not need to be restacked to deliver the digital dividend. It does
include currently operating digital channels that are in the digital dividend spectrum but also
includes an alternative block plan channel.
Although primarily aimed at identifying channels for a variation to the RRWA DCPs, the
engineering report also considers block channel options for services in the Perth TV1 licence
area, including options at analog retransmission sites in the event they are to be converted to
digital. However, it is not proposed to vary the Perth DCP at this time.

2. Scope and channel selection
process
2.1 Overview
The scope of this engineering report encompasses all sites in the Remote and Regional
Western Australia (RRWA) licence areas where channels for terrestrial digital television
services have been previously planned. The report also considers sites in the Perth TV1
licence area to ensure that sufficient spectrum will be available at those sites but they will not
be included in the current variations to the DCPs.
2.2 Planning Principles
This engineering report was commenced prior to the drafting and decisions on the restack
planning principles. The approach taken is generally consistent with the restack principles.
However, there may be some slight but inconsequential differences.
1. This engineering report has adopted the following channel blocks.
Block Identifier Channels
6 | acma
Block A*
Block B
Block C
6 7 8 10 11 12
28 29 30 31 32 33
34 35 36 37 38 39
Block D 40 41 42 43 44 45
Block E 46 47 48 49 50 51
* Channels 9 and 9A may be used for digital TV in some remote areas.
2. Six services have been planned at all sites except for Mandurah (nine services) and
Broome (seven services).
3. The engineering report aims to identify a channel block at each site with channels that are
adjacent or very near to existing operating analog and digital services.
4. All channels have been kept below channel 52 so that channels are not planned within
the digital dividend spectrum.
5. Coverage of the restacked services is expected to be similar to coverage of currently
operating analog and digital services with transmission power levels determined on the
same basis as the originally planned DCP services.
6. In accordance with the Ministerial Direction two VHF Band III channels have been left
clear for potential future regional Terrestrial Digital Audio Broadcasting (T-DAB) planning
in and around the Perth licence area. In more populous areas the reservation for digital
radio was channels 9 and 9A. However, in more remote areas these channels may be
proposed for digital television services to avoid potentially unnecessary changes to
operating digital television services. At least one VHF television channel is available for T-
DAB at each site.
7. “Single antenna” VHF Band III only or UHF only solutions, and changes to avoid channel
sets with a wide span of UHF channels where adopted were this had little or no impact for
viewers or broadcasters.
8. In a limited number of cases some of the channels identified for sites may not be
available until after analog switchover (ASO).

2.3 Licence Areas
There are six television licence areas in Western Australia. Perth TV1 has three commercial
licensees: TVW owned by the Seven Network, STW owned by WIN and NEW owned by the
TEN Network. It is classed as a metropolitan licence area for the purposes of the conversion
schemes and, while channel options are considered in this engineering report, there will not
be a Variation to the Perth DCPs at this time.
The remaining licence areas are considered to be remote licence areas for the purposes of
the conversion schemes and are often grouped together as the Remote and Regional WA
licence areas.
WIN holds a broadcasting service licence to operate a commercial television service in the
Remote and Regional WA TV1 using the callsign WOW.
GWN (owned by Prime Television) and a joint venture between GWN and WIN licensed
under s38B of the BSA, hold broadcasting service licences to provide commercial television
services in each of the:
� South West and Great Southern TV1 licence areas using callsigns SSW and SDW;
� Kalgoorlie TV1 licence areas using callsigns VEW and VDW;
� Geraldton TV1 licence areas using callsigns GTW and GDW; and
� Western Zone TV1 licence area using callsigns WAW and WDW.
The four licence areas South West and Great Southern TV1, Kalgoorlie TV1, Geraldton TV1
and Western Zone TV1 overlap each other and completely overlap the Remote and Regional
WA TV1 licence area. The South West and Great Southern TV1 and Remote and Regional
WA TV1 licence areas also overlap the Perth TV1 licence area as well as in area around
Mandurah.
The ABC has traditionally been given a unique callsign for “transmitter” sites, ie ABSW and a
“generic” callsign, ABW, for translator or satellite fed sites. This convention has not been
rigorously applied over the years and can lead to some confusion. For the purposes of clarity,
the generic ABW callsign has been used for all ABC services in Western Australia.
2.4 Geographic areas considered in this report
This engineering report has partitioned Western Australia into eight areas as shown below in
figures 1, 2 and 3, to make the analysis and consideration of channel options more
manageable. The areas are in general independent of each other in terms of coverage and
interference analysis; however, during the interference study on a particular site, the potential
interferers from other areas were also identified and taken into account.

The colour coding of the sites shown in Figures 1, 2 and 3 is as follows:
Green: sites with one or more currently planned digital channels, and “retransmission”
sites within the Perth TV1 licence area;
Yellow: “retransmission” sites with all services below channel 52 and therefore potentially
impacting on restack proof channel options at broadcaster sites.
“Retransmission” sites with all channels above 51 are not shown and have not been
considered in this report.

2.5 Broadcast sites considered in this report
The following sites requiring services to be implemented under the conversion schemes have
been considered in this engineering report. Appendix 3 provides detailed information on
services currently operating or planned at these sites.
Area 1: Perth region (Perth TV1 licence area)
� High power site: Perth;
� Other broadcaster sites: Toodyay, Roleystone and Mandurah (not a Perth TV1
broadcaster site);
� Retransmission sites: Perth East, Lancelin, Maryville, and Seabird.
Mandurah is located in an overlap between the Perth TV1 and the South West and Great
Southern TV1 licence areas. It has four operating analog services, ABW, SBS, SSW and
WOW, providing national and regional commercial analog services into Mandurah. The SBS
has a digital service at Mandurah on channel 53 and the regional commercial broadcasters
will be implementing digital services there under the conversion schemes. The ABC was
funded in the 2011 budget to provide an ABC digital service at Mandurah. The metropolitan
commercial broadcasters have identified Mandurah as a “gapfiller” site from which they wish
to extend the coverage of their digital services in to Mandurah and the southern areas of the
Perth TV1 licence area. Mandurah is a Remote and Regional WA site but has been
considered in this engineering report as a potential overlap site which will eventually have
nine digital services (two national, three Perth commercial, three remote commercial and one
unassigned).
The Perth commercial licensees have proposed converting to digital the analog
retransmission services at Lancelin, replacing the Perth East analog retransmissions with
wider coverage Perth Central gapfillers and implementing a new Perth Coastal gapfiller. They
have also indicated they will not fund the conversion to digital of the Maryville or Seabird
analog retransmission services. This engineering report has only partly considered the
Mandurah and Perth Central gapfillers as there was only limited information available at the
time. It has not considered channel options for a Perth Coastal gapfiller. It has assumed the
conversion of the Lancelin retransmission services and has also considered channel options
should Maryville and Seabird be converted by the current licensee.
Area 2: Bunbury/Great Southern region
� High power site: Bunbury, Southern Agricultural and Wagin in the South West and
Great Southern TV1 licence area;
� Other broadcaster sites:
10 | acma
o Albany, Bridgetown, Katanning, Kojonup, Manjimup, Margaret River, Nannup
and Narrogin in the South West and Great Southern TV1 licence area;
o Augusta, Lake Grace and Pemberton in the Western Zone TV1 licence area;
� Retransmission sites with operating analog services below channel 52: Hyden and
Kulin in the Western Zone TV1 licence area
While Albany is a “broadcaster only” sites, the closely related nearby “retransmission only”
site of Albany West was also taken into account in this engineering report.

Area 3: Central Agricultural region
� High power site: Central Agricultural in the South West and Great Southern TV1
licence area;
� Other broadcaster sites:
o Bruce Rock and Northam in the South West and Great Southern TV1 licence
area;
o Koolyanobbing, Merredin, Southern Cross and Southern Cross Town in the
Kalgoorlie TV1 licence area;
o Narembeen in the Western Zone TV1 licence area;
� Retransmission sites with operating analog services below channel 52: Kellerberrin in
the Kalgoorlie TV1 licence area and Mukinbudin in the Western Zone TV1 licence
area.
There are a number of sites around the Central Agricultural high power site where WIN
implemented low power analog services on channel 44. These sites are Beverly, Brookton,
Corrigin, Cunderdin, Dowerin, Goomalling, Pingelly, Quairading, Tammin, Wyalkatchem, and
York and they have been lumped together in this report as “Analog 44”.
Area 4: Geraldton/Mid West region
� High power site: Geraldton in the Geraldton TV1 licence area;
� Other broadcaster sites:
o Carnamah, Kalbarri, Mingenew, Morawa, Mullewa and Perenjori in the
Geraldton TV1 licence area;
o Cervantes, Cue, Dalwallinu, Eneabba, Jurien, Leeman, Meekatharra, Moora,
Moora Town, Mount Magnet, Wongan Hills and Wongan Hills Town in the
Western Zone TV1 licence area;
� Retransmission sites with operating analog services below channel 52: Green Head
in the Geraldton TV1 licence area.
While Moora and Wongan Hills are “broadcaster only” sites, the closely related nearby
“retransmission only” sites of Moora Town and Wongan Hills Town were also taken into
account in this engineering report.
Area 5: Kalgoorlie/Esperance region
� High power site: Kalgoorlie in the Kalgoorlie TV1 licence area;
� Other broadcaster sites:
o Esperance, Kambalda and Norseman in the Kalgoorlie TV1 licence area;
o Condingup/Howick, Hopetoun (WA), Ravensthorpe and Salmon Gums in the
Western Zone TV1 licence area;
Area 6: Pilbara region
� Other broadcaster sites:
o Dampier, Karratha, Marble Bar, Newman, Pannawonica, Paraburdoo, Port
Hedland, Roebourne and Tom Price in the Western Zone TV1 licence area;
� Retransmission sites with operating analog services below channel 52: Karratha
South and Nullagine in the Western Zone TV1 licence area.
� A seventh channel may need to be identified for Roebourne which has an HPON
service which may be implemented in digital.
acma | 11

Area 7: Kimberley region
� Other broadcaster sites:
o Argyle, Bayulu, Broome, Derby, Fitzroy Crossing, Halls Creek, Kununurra,
Kununurra East and Wyndham in the Western Zone TV1 licence area;
� Retransmission sites with operating analog services below channel 52:
Wurrenganginy Community in the Western Zone TV1 licence area.
A seventh channel needs to be identified for Broome which has an HPON service which is
likely to be implemented in digital.
Area 8: Remainder of WA
� Other broadcaster sites:
o Carnarvon, Denham, Exmouth, Laverton, Leinster, Leonora, Menzies and
Onslow in the Western Zone TV1 licence area.

3. Interference Compatibility
Results of the interference compatibility study are summarised in the form of compatibility
matrices in Appendix 4. In this subsection, only findings relating to the major compatibility
issues are presented.
The ACMA modelling process is relatively conservative and potential, rather than actual,
interference problems are identified in the following sections. This analysis can inform
channel allotments that will avoid or minimise potential interference problems and highlight
areas where attention needs to be paid to the potential impact on viewers‟ reception.
In practice, these predicted interference problems may not occur because the modelling does
not account for local terrain, building and foliage which will affect interfering and wanted
signals. The modelling may also not accurately reflect the actual transmission parameters
(antenna patterns, vertical null fill, beam tilt, radiated power, antenna height and transmission
site) and may therefore predict coverage and interference that does not exist.
3.1 Area 1: Perth Region
The major issues identified in the Perth region are:
1. Perth East/Central retransmission conversion:
Perth East was analysed as a digital version of the current analog retransmission services. It
is likely, though, that if implemented by the Perth commercial broadcasters it will be at a
different site with wider coverage. The ACMA may adopt a general area served name of
“Perth Central” to distinguish a new gapfiller from the analog retransmission. The commercial
broadcasters have also proposed a new Perth Coastal gapfiller. The following comments
provide a general indication of channel options for new Perth gapfillers but further analysis will
be required when confirming the specifications for the gapfillers.
Compatibility between Perth East and Central Agricultural, Mandurah and Moora was
assessed using four different propagation models.
a) L&S VHF/UHF propagation model studies suggest that Perth East services can be
co-channelled with each of the Central Agricultural, Mandurah and Moora services
with minor interference issues, very likely outside the Perth East coverage area;
b) Studies with the CRC Predict propagation model suggest that Perth East services
should not be co-channelled with the Mandurah and Moora services due to
predictions of very high levels of interference from these services. Co-channelling
with Central Agricultural services could be possible, since the Perth East suburban
coverage area appeared not to be affected, even though other parts of the Perth East
suburban coverage contour (that would however be covered by the main Perth
services) might suffer significant interference.
Due to significant differences between the results obtained with the L&S VHF/UHF and
CRC Predict propagation models at this site, further studies were performed with the Rec.
ITU-R 1812 and 1546-1 propagation models. The following results were obtained:
a) The Rec. ITU-R 1546-1 propagation produced results were very similar to those
obtained using the L&S VHF/UHF model.
b) The Rec. ITU-R 1812 propagation model results suggested that co-channelling with
the Mandurah and Moora transmitters was not feasible. The results produced by this
model were very similar to those of the CRC Predict model. However, the same
model suggested co-channelling with Central Agricultural services was feasible,
showing virtually no interference within the Perth East coverage area including the
areas of interest.
acma | 13

As a result of these analyses it was concluded that the Perth East and Central Agricultural
services can be co-channelled. However, co-channelling of Perth East services with
Mandurah and Moora services should be avoided.
2. Roleystone: Interference studies with the CRC Predict and L&S VHF/UHF propagation
models suggested that Roleystone services can be co-channelled with Mandurah
services. This conclusion was reached after “masking” the Roleystone rural and
suburban contours with the Perth coverage using the Best Server analysis.
a) The Best Server analysis also suggested possible co-channelling with Central
Agricultural services. However, there were some very minor interference spots
predicted even after masking 4 by the Perth services.
b) Bunbury digital services would cause interference along the northern edge of the
Roleystone coverage area that would not be masked by coverage from the main
Perth services, while the rest of the coverage area is mostly interference free. Since
this interference appears to be more significant than that caused by Central
Agricultural services, it is concluded that co-channelling Roleystone and Bunbury
services should be avoided.
3. Mandurah: Co-channelling between the Mandurah and Central Agricultural services is
acceptable if protection is limited to the principle Mandurah coverage areas. Within the
rural contour some interference fringes exist east and south-east of Mandurah.
a) Moderate interference from Roleystone is predicted to occur to the Mandurah service
depending on which propagation model is used. When using the 1546-1 propagation
model interference only occurs in areas best served by Perth. When using the CRC
predict propagation model however for the metro services 250 people out of 25,000
people may be potentially affected by interference from Roleystone. Most of these
people are located along the Western side of Harvey Estuary in towns such as
Dawesville and Bouvard. For the regional services 670 people may be potentially
affected out of 46,000 people. Again most of these people are located along the
Western side of Harvey Estuary in towns such as Dawesville and Bouvard. For
national services, 140 people out of 18,500 may be potentially affected. Again most of
these people are located along the Western side of Harvey Estuary in towns such as
Dawesville and Bouvard. This could be a concern however due to the relatively flat
terrain around the target area the 1456-1 propagation model is probably more
relevant in this case..
b) Moderate interference from Central Agricultural could occur to the Mandurah
coverage depending on which propagation model is used. When using the 1546-1
propagation model depending on whether you mask Mandurah with Perth or Bunbury
only between 29 and 462 people may be potentially affected. When using the CRC
predict propagation model the population increases significantly to between 7,500
and 13,000 people may be potentially affected. This could be a concern however due
to the relatively flat terrain around the target area the 1456-1 propagation model is
probably more relevant in this case.
4. Toodyay: Toodyay services cannot be co-channelled with Central Agricultural services.
a) Co-channelling with Northam services appears to be feasible. Some interference
between the Toodyay and Northam services is evident even after the Best Server
analysis and masking. However, this interference appears to be confined to
unpopulated areas and is therefore considered to be acceptable.
4 The term “masking” in this context means the deletion from a prediction result of areas better served by an
alternative site, in this case the main Perth transmissions.
14 | acma

) Co-channelling with Moora services could be possible. After masking by Perth, the
interference appears to be limited to unpopulated areas. However, it is suggested
that this co-channelling should be avoided if possible.
5. Lancelin: It is preferable to avoid co-channelling Lancelin and Geraldton if possible,
although it may not be practicable in practice
a) Moderate interference. When using the 1546-1 propagation model a population of 14
out of 1100 are predicted to receive interference. However when using the CRC
Predict propagation model a population of 200 out of 1200 are predicted to receive
interference, after excluding population outside the Perth licence area. This is
reduced to 170 if the population best served by Perth are removed and again reduced
to 90 when population outside the suburban coverage are removed. Half the
population in the small town of Ledge Point (population of about 160) may be
potentially affected by interference from Geraldton. If masked to suburban level,
minor interference is predicted to occur at the edge of the suburban coverage.

3.2 Area 2: Bunbury/Great Southern Region
The following issues have been identified in this region.
1. Narrogin: The coverage of the Narrogin services would be significantly affected by
interference from the Perth, Wagin, Central Agricultural and Bunbury services if cochannelled.
Therefore, co-channelling with those services should be avoided if possible.
When taken together with the constraint of protecting operating analog and digital
services, this significantly reduces the channel options that are available for Narrogin
digital services.
2. Kojonup: After detailed interference analysis, it was found that Kojonup cannot be cochannelled
with Wagin and Bunbury services. Additional analysis showed that cochannelling
with Central Agricultural, Katanning or Narrogin services could be possible if
the Kojonup services are protected to the suburban contour. These three services are
predicted to produce similar interference impacts into Kojonup, with Narrogin providing a
more favourable co-channel pairing than Central Agricultural or Katanning.
3. Southern Agricultural: Assuming a VHF option at Southern Agricultural, when using
CRC Predict propagation model, co-channel Interference from Perth at the edge of
coverage is predicted to potentially affect a population of 4137 out of 47314. 2910 of this
potentially affected population are in UC/L 5 s (ie towns). If a best server plot is used to
remove areas not best served by Southern Agricultural then the potentially affected
population reduces to 950, with 347 of these in UC/Ls, primarily Gnowangerup, which has
analog retransmissions. Southern Agricultural best serves 34816 people. Converting
Gnowangerup would remove up to 334 people out of 347 people potentially affected in
UCL/s. As Gnowangerup has analog retransmission, if the services are not converted to
digital, affected viewers in the town would be able to access the VAST satellite services
and would have access to the satellite subsidy scheme. Alternative services for viewers
affected by co-channel interference from Perth would be the Wagin, Katanning, Kojonup,
Manjimup, Pemberton and Albany services.
3.3 Area 3: Central Agricultural Region
1. Northam: Northam and Toodyay have identical channel constraints, so it is proposed that
Northam and Toodyay services would have the same channel allotments. Refer to the
Toodyay discussion.
2. Southern Cross: Wider coverage ABC service only, other services have low power
services covering the town of Southern Cross. The total population predicted to be
covered is 1144. When using the CRC Predict propagation model, interference from cochannelled
Perth VHF services, inside the UC/L of Marvel Loch, could potentially affect a
population of 12 out of 99. The Southern Cross UC/L, with a population of 710 is
unaffected. Outside the UC/L‟s a population of 7 is predicted to have interference. If a
UHF ABC service was implemented at Southern Cross Town in add to the out-of-town
VHF Southern Cross ABC service, then the Southern Cross VHF ABC service would only
best serve a population 11 people, of which only one is predicted to suffer interference.
This 1 person is not inside a UC/L.
3.4 Area 4: Geraldton/Mid West Region
The major issues in this area are:
1. Morawa (ERP adjusted to 3kW in Band IV and 3.25 kW (ABC service) in Band III), Moora
(ERP adjusted to 30 kW) and Dalwallinu (ERP adjusted to 5 kW) cannot be cochannelled.
In addition, Wongan Hills (ERP adjusted to 1.6 kW), is in the same area and
5 UC/L – ABS census unit for Urban Centre/Locality. Used in planning to indicate the likely concentration of
population in towns.
16 | acma

cannot be co-channelled with either Moora or Dalwallinu, but can be co-channelled with
Morawa services. Co-channel operation of Morawa analog and Moora digital services
appears to be possible, with some minor interference predicted in both directions, but this
is limited to very sparsely populated areas.
Co-channelling Perth and Morawa Band III digital services should be avoided due to
predicted interference in both directions.
The Moora and Dalwallinu services should not be co-channelled with Central Agricultural
services. These constraints, after considering currently operating analog and digital
services, leave a total of only 10 UHF Band V channels available for Moora and
Dalwallinu. This should not be a major problem as Dalwallinu is unlikely to have
commercial digital services, at least of an equivalent ERP to the ABC.
In addition, as suggested earlier in this report, co-channelling Moora and Toodyay (and
therefore Northam), should be avoided.
2. Wongan Hills: Co-channelling Perth and Wongan Hills is not possible due to serious
interference from Perth into Wongan Hills.
3. Leeman UHF and Eneabba: Leeman has a VHF ABC service at a different site with
wider coverage than the other Leeman retransmission services. Co-channelling Eneabba
and Leeman in the UHF band with services equivalent to the VHF ABC site and coverage
is predicted to cause significant interference in both coverage areas that has potential to
affect a sizable number of people.
4. Leeman VHF and Perth: Significant interference is predicted to occur within the town of
Leeman when using CRC Predict propagation model, although the Leeman ABC service
is already operating, co-channelled with a Perth digital service on channel 6. The
predictions could indicate an interference problem which is not apparent to viewers as
only one service, the ABC, is operating. If this is the case then increasing the ERP of the
Leeman VHF services may be the appropriate solution. Alternatively, the propogation
model may be giving
Note: Wherever practical, channel sets for coastal sites were chosen to avoid the channels
used for Geraldton services.
3.5 Area 5: Kalgoorlie/Esperance Region
Two issues were identified in this area:
1. Predictions indicate that the Esperance services should not be co-channelled with
Salmon Gums and Condingup/Howick services in VHF Band III. Salmon Gums is
currently a VHF Band III only site, Esperance is mixed VHF/UHF site and
Condingup/Howick is a mixed, but predominantly, VHF site.
2. Predictions indicate co-channelling of Kalgoorlie and Norseman services should be
avoided. Analysis performed using the L&S VHF/UHF and CRC Predict propagation
models in both UHF and VHF bands shows significant potential interference from
Kalgoorlie into southern parts of the Norseman township that lie within the suburban
contour. No interference issues were found for the case of Norseman into Kalgoorlie. The
major cause of the interference is the significant lobe in the Kalgoorlie HRP which was
used to provide an off-air input to Kambalda. This off-air link is no longer required and
VHF could be used at both sites if the antenna at Kalgoorlie was changed to reduce the
ERP toward Norseman.
3.6 Areas 6, 7 and 8: Pilbara, Kimberley and remainder of WA
1. Laverton, Leinster, Leonora and Menzies: Leinster is a predominately Band III site,
while, the other three sites are predominantly Band V sites. Laverton, Leinster and
Menzies can be co-channelled. These three sites could also possibly be co-channelled
with Leonora, since the predicted interference appears to be limited to unpopulated areas
acma | 17

around, but outside, Leonora. However, since all Band IV and Band V channels are fully
available there is no need for co-channelling.
In addition, co-channelling of Menzies and Kalgoorlie services should also be avoided,
but since Kalgoorlie is a Band III site and since Menzies is being proposed as a UHF site,
this does not impose a constraint on planning.
2. Current channel allocations at Carnarvon, Exmouth and Newman do not allow provision
of three VHF digital channels (for three commercial broadcasters) before the analog
switchover at these three sites.
3. The Cue television transmission site is located approximately 147 km from the central
point of the radio quiet zone of the proposed SKA radio telescope. ACMA‟s Embargo 41
requires that no new 100 - 230 MHz assignments (including VHF television services)
should be made within 150 km and that no new 230 MHz – 25.25 GHz assignments
(including UHF television services) should be made within 100 km of the central point of
the radio quiet zone. However, discussions with CSIRO indicate that VHF will be less of a
concern than UHF. Therefore, VHF is proposed.
4. Kununurra: Kununurra and Wyndham are both currently predominantly VHF sites with
existing digital to analog co-channel arrangements. Predictions indicate that cochannelling
digital services at Kununurra and Wyndham may cause interference in the
Kununurra coverage area, potentially affecting a population of 38 out of 695. Nevertheless,
VHF appears to be the most practical solution at both Kununurra and Wyndham, and the
affected population is likely to be less than predicted when local obstructions and actual
transmission details are considered. Common allotments are proposed for Kununurra and
Wyndham so that services could be implemented in an SFN arrangement if necessary.

4. Channel Plans
4.1 Overview
This section presents a detailed “block” plan for all DCP sites in Western Australia. The
channel plan is the outcome of the extensive interference analysis and detailed channel
planning process that has been discussed in sections 2 and 3 and related Appendices. The
proposed channel plan is contained in Tables 1 to 8. In each table, the current channel
arrangements are shown together with the arrangements that would apply after the proposed
revision to the DCPs is completed. The proposed revised channel arrangements are shown
in the rows with orange shaded „area served‟ name labels in the tables. (Rows with
uncoloured „area served‟ names show the current channel arrangements).
The colour code used in the tables is explained below;
Currently operating digital service;
Currently operating analog service;
Currently operating digital radio (T-DAB) services/ subband.
Currently planned digital service;
Proposed revised digital service: channel available immediately;
Proposed revised digital service: channel not available immediately;
Optional channel (explained in more detail with the channel plans)
All services above channel 51 (coloured in light yellow in the tables) will need to be cleared
from the 694-820 MHz Digital Dividend frequency range.
For the sake of the brevity of presentation, sites with a single analog WOW service operating
on channel 44 (in the Central Agricultural area) have been represented by a single row in the
relevant channel plan table and denoted “Analog 44”. These sites are: Beverly, Brookton,
Corrigin, Cunderdin, Dowerin, Goomalling, Pingelly, Quairading, Tammin, Wyalkatchem, and
York.
As a general principle changes to already licensed digital channels were avoided, however at
a small number of sites it is proposed that channels of some already licensed ABC and SBS
services would be moved so that sites become either purely VHF or purely UHF sites. The
rationale for the changes is provided in section 5.
The most important of these proposed changes are at the Perth and Southern Agricultural
(high power) sites and at the Albany (low power) site. Perth and Southern Agricultural are
proposed to be solely VHF sites. These changes require that the operating Perth SBS29
digital service 6 and the operating Southern Agricultural SBS29 digital service 7 should shift to
VHF Band III. Moving those services from UHF (especially the Southern Agricultural SBS29
service) will produce a significantly better channel planning solution at a number of
surrounding sites where channel availability is directly affected by Perth and Southern
Agricultural. More details are provided in the discussion following Table 2.
The Perth changes are a direct requirement of the Ministerial Direction, and the Southern
Agricultural/Albany changes are consequential to the Ministerial Direction in that without the
6 Note that unless the current law changes, the trial digital community television service on channel 32 will cease at
the end of 2013.
7 At the time when six separate digital channels are required at Albany/Southern Agricultural.
acma | 19

Southern Agricultural change insufficient UHF channels will be available for planning in the
Katanning/Kojonup/Wagin area.
Other sites where changes to licensed ABC digital services are proposed are: Morawa,
Norseman, Southern Cross and Wongan Hills. These sites have an already operating ABC
VHF Band III service. The Morawa, Southern Cross and Wongan Hills changes are all
consequential to requirements of the Ministerial Direction. The Norseman change is
proposed to avoid a situation where one of six services at Norseman would be an “orphan”
channel in band different to that of other services at the site. This is an undesirable situation
as it requires viewers to have dual band antennas which can lead to less than optimal
reception, particularly of the orphan channel.
At Leeman, Southern Cross and Wongan Hills, the ABC currently operates at a different site
from the other services serving the area. Operation of services intended to cover the same
area from significantly separated sites can lead to concerns about adjacent channel
interference and also can result in compromised reception of services from one or both site if
viewers do not install appropriate dual antenna systems. Therefore, channel selection at
those sites may require further consideration if the ABC service continues to operate at its
current site.
Many of the above-described band or channel changes are required to achieve an optimised
six-channel-per-site block plan. However until such time as all six channels are actually
required, the need to make the changes described above may be able to be deferred.
Section 5 provides more information.
The Broome case also has an additional complexity. At Broome a seventh channel (a HPON
service) currently operates as an analog service on UHF channel 35, and a notional digital
conversion of that service has been planned on UHF channel 31, however given the
remoteness of Broome it may be possible to allocate a seventh channel in the VHF range
post switchover without compromising the ability to provide a future digital radio service.
However the desirability or otherwise for this channel to be relocated to VHF Band III would
require further consideration which is outside the scope of this report.
In a small number of cases some of the proposed digital services are constrained by currently
operating digital services below channel 52, which are required to be moved to a different
channel at some point in future. For each case, Appendix 5 provides a sequencing diagram
that shows the steps required before the service in question could start operating (together
with appropriate explanation). These cases are also explained in detail after corresponding
channel plan tables (in the remainder of this section).
Finally, an analysis of the need (or otherwise) for hard cut-over transitions (i.e. non-simulcast
transitions) from analog to digital channels is included in section 5.3. It concludes that in
nearly all cases if channel assignments are carefully chosen there will be minimal hard cutover
issue.

4.2 Area 1: Perth Region
Table 1: Channel arrangements for Area 1: Perth Region before and after the proposed revision
Perth: The currently licensed SBS digital service on channel 29, and the sixth unassigned channel, are moved to Band III, which would make Perth a pure
VHF Band III site. These changes cannot occur until after currently operating VHF analog channels at Perth are vacated. The Perth changes (together with a
similar change at Southern Agricultural) would also make channel 29 available for other services in Area 2. Further discussion on this topic is provided in the
text following Table 2. Moving all Perth services to VHF will avoid a severe co-channel interference pairing between Perth and Narrogin which would prevent
all six channels being available for digital services at Narrogin (refer to Area 2 table for Narrogin).
Perth East, Maryville, Lancelin and Seabird: The proposed channel allotments depend upon discussions with Metropolitan broadcasters about which of
these retransmission sites may be converted to digital and what new gapfiller services may be implemented in the Perth TV1 licence area.
Toodyay: All five currently licensed Toodyay digital services (two national and three commercial) are above channel 51. Four Toodyay services (three
commercial and one national service) may be allotted on channels that will only become available after the analog switchover avoiding a “hard cutover” from
analog to digital at this site. Channel 51 is proposed to be the unassigned channel. The constraints on finding restacked digital channel at Toodyay are that
channel 50 will not available for use until after the Central Agricultural SBS47 and SSW50 analog services close, and channels 46 and 49 are constrained by
Toodyay analog services. Central Agricultural services SBS48 digital and SSW50 analog are expected to move when Central Agricultural digital services are
implemented in 2012, after which channels 48 and 50 would be clear at Toodyay.
acma | 21

In order to avoid co-channelling with Moora and Central Agricultural digital services, Toodyay needs to be co-channelled with Northam. Interference analysis
suggests there may be some potential interference from Northam into Toodyay but the predicted inference falls in unpopulated areas. Furthermore there is a
long standing analog-analog pairing between Northam and Toodyay. In addition, in the current DCP, interference protection of Toodyay analog services has
only been planned within their suburban contour. According to analysis, no interference from Northam is observed within the suburban contour.
Mandurah: Mandurah is located in the overlap area between the Perth TV1, South West and Great Southern TV1 and Remote and Regional WA TV1 licence
areas, and therefore, nine digital channels have been proposed at that site. Channels 33 and 40 are restricted by Bunbury SBS33 analog and the relocated
Bunbury WOW40 analog (shifted from 39), until RRWA ASO.
22 | acma

4.3 Area 2: Bunbury/Great Southern Region
Table 2: Channel arrangements for the Area 2: Bunbury/Great Southern region before and after the proposed revision
acma | 23

Albany: Albany requires a number of changes to operating analog and digital services to free up channels at Southern Agricultural and to allow a restack
proof commencement at Albany.
Southern Agricultural: It is proposed that currently licensed SBS29 digital service at Southern Agricultural should be moved to VHF Band III. That would
make Southern Agricultural a pure VHF site. In addition, since it is proposed to move SBS services at both Perth and Southern Agricultural to VHF Band III,
channel 29 will become available for use elsewhere. The alternative approach of making Southern Agricultural into a full UHF site was not considered
practical due to the difficulty of finding compatible UHF channel sets for each of the surrounding Wagin, Katanning, Kojonup and Bunbury areas.
There are a number of consequential analog and digital channel changes required to allow all five digital services to be implemented in Block A at Southern
Agricultural. Albany WOW43 analog to 52, Albany ABW8 digital to 43 and Albany SSW10 analog to 55 and Katanning SSW10 analog to 9A. The currently
operating Southern Agricultural SBS29 service will need to move to channel 10 and the timing of this shift depends on when the channel is made available
through the proposed changes at Albany, site work at Southern Agricultural at the management of interference to Wagin analog services. Southern
Agricultural digital services on channels 6 and 8 may cause interference to approximately 3000 viewers of the Wagin SSW6 and ABW8 analog services.
Wagin commercial digital services should commence well before the commencement of Southern Agricultural digital services (say three months) so that
potentially affected Wagin analog viewers can convert to digital. A communications campaign should be implemented to ensure timely and appropriate
advice.
Kojonup: Kojonup is co-channelled with Narrogin. This appears feasible as there are currently co-channelled analog services.
Nannup: Nannup is currently planned as a Band IV/low Band V site. It is preferable to avoid co-channelling with Bunbury (Block C) so Nannup can use block
B co-channelled with Pemberton. Co-channelling Bunbury digital and Nannup analog services would appear to be practicable until switchover. The currently
licensed Nannup ABW31 digital service will not have to move due to the use of Block B. Until ASO the WOW33 digital service will operate co-channelled with
Bunbury SBS33 analog. Predictions indicate that there shouldn‟t be unacceptable interference in the populated areas of the Nannup coverage.
Pemberton: Pemberton is currently planned as a predominantly Band IV/low Band V site. It is preferable to avoid co-channelling with Bunbury (Block C) so
Pemberton can use block B co-channelled with Nannup. Co-channelling Bunbury digital and Pemberton analog services would appear to be practicable until
switchover. The currently licensed Pemberton ABW32 digital service will not have to move due to the use of Block B. Until ASO the WOW33 digital service
will operate co-channelled with Bunbury SBS33 analog. Predictions indicate that there shouldn‟t be unacceptable interference in the populated areas of the
Pemberton coverage.
Wagin: Wagin VHF analog services may suffer interference from co-channel Southern Agricultural VHF digital services. The Wagin commercial UHF digital
services should commence some time (a few months) before the Southern Agricultural VHF digital services to give potentially affected viewers the opportunity
to convert to digital. Channel 32 is constrained by the operating Wagin WOW32 analog service and currently planned Perth UA32 digital, so is left
unassigned. The Perth UA32 will be replaced by channel 10 after ASO in Perth TV1 licence area. A sequence of steps before a Wagin channel 32 digital
service could start is shown in Figure A5.1 in Appendix 5.
24 | acma

4.4 Area 3: Central Agricultural Region
Table 3: Channel arrangements for Area 3: Central Agricultural region before and after the proposed revision
Koolyanobbing: Koolyanobbing is currently a purely VHF site that has three analog services and, given the objective of avoiding viewer antenna changes,
Koolyanobbing should be retained as a VHF only site. Predictions indicate that Koolyanobbing is not compatible with Southern Cross digital services, but it is
compatible with Southern Cross analog services. Currently, there are three operating Band III services at Southern Cross (two analog and one digital), this
leaves four channels immediately available at Koolyanobbing. If channels 9 and 9A are left vacant for potential future digital radio services, only two channels
would be immediately available for VHF digital services at Koolyanobbing. As four digital channels are required, three commercials and the ABC, a DOLMA
will be required.
Southern Cross: As discussed above, making Koolyanobbing an all VHF site would consequentially require Southern Cross to be a UHF if more than one
VHF digital service is required at Southern Cross or when a sixth digital service is required at Koolyanobbing (assuming two TV channels are kept clear for
T-DAB in the Central WA region). Until the sixth channel is required at Koolyanobbing the Southern Cross ABW7 digital service does not need to shift to a
UHF channel.

4.5 Area 4: Geraldton/Mid West Region
Table 4: Channel arrangements for Area 4: Geraldton/Mid West region before and after the proposed revision
26 | acma

Table 4 (cont): Channel arrangements for Area 4: Geraldton/Mid West region before and after the proposed revision
Cervantes and Eneabba: Due to operating ABW46 and WOW49 analog services at both Cervantes and Eneabba, two of the proposed Cervantes and
Eneabba channels cannot be used until after analog switchover. This, however, is not expected to be an issue as no commercial digital rollout is planned for
these sites. The commercial analog services are retransmissions and could be switched off, if necessary, without a DOLMA.
Dalwallinu: Other interference and channel planning constraints dictate that channels for Dalwallinu should be toward the top of the UHF range. However
due to potential co-channel interference between Dalwallinu and Central Agricultural services it is necessary to avoid use of channels 47, 48 and 50. This,
however, is not expected to raise a hard cutover issue since channel changes at Central Agricultural will clear channels 47 and 50 and no commercial rollout
is expected.
Kalbarri: The SBS service is proposed to be located on channel 7 to avoid potential interference from/to a Geraldton digital radio service if it were to be
implemented on channels 9 or 9A. This however means that the notional Kalbarri SBS7 digital service could not operate until the WAW7 Kalbarri analog
retransmission service ceases operation. But given that there is currently no current analog SBS service at Kalbarri it seems unlikely that a digital SBS
service would arise in the immediate future. However, if necessary the analog WAW7 retransmission service could cease operating, without the need for a
DOLMA, to allow an SBS digital service to commence.
Leeman: Leeman is a site where, under the Commercial Television Conversion Scheme, there is no obligation for commercial broadcasters to provide
terrestrial digital services. However, if commercial broadcasters decide to provide terrestrial digital services at Leeman, it would be desirable to move the
currently operating ABW6 digital service to the UHF band (an optional channel has been provided to cover this eventuality). Alternatively, if terrestrial
commercial digital services do not proceed at Leeman, the ABW6 digital service could remain in VHF Band III.
acma | 27

Morawa: Due to current operating/planned channel arrangements, Morawa is proposed to be a Band IV UHF site. The interference study showed digital to
digital VHF interference incompatibility between Perth and Morawa. Therefore, it is proposed that the currently operating Morawa ABCMW7 digital service
should be moved to UHF channel 28. This change should occur before the ASO in Perth so that the Perth SBS29 digital service can move to channel 7 as
soon as the ASO happens.
In moving to channel 28 and, presumably, providing similar coverage to the other Morawa services, the ABC is encourage to consider establishing local
digital transmissions at Perenjori, Carnamah and Mingenew to provide equivalent coverage to the other services which have local transmissions for these
towns.
Several of the proposed Morawa channels are not immediately available. The proposed GTW29 service is constrained by the operating Geraldton analog
SBS29 and Perth digital SBS29 services. The proposed GDW32 service is constrained by the operating Geraldton analog WOW32, and Perth digital UA32
services which is proposed to move to channel 10. However, the UA32 service at Perth could not move to channel 10 before the ASO in Perth TV1 licence
area. A detailed sequencing diagram that shows the constraints on the availability of Morawa channels is shown in Figure A5.1 in Appendix 5.
The digital SBS40 service at Morawa was launched in June 2010 and was funded by the Shire of Morawa Council. In the communication between the ACMA
and the Shire of Morawa, and between the ACMA and N-COM Pty Ltd, the ACMA indicated that the spectrum arrangement in WA is under review and that
channel 40 was not likely to be a long term solution for the digital SBS service at Morawa. Both the Shire of Morawa and N-COM Pty Ltd understood and
accepted that the SBS40 channel would need to be re-tuned to a different channel after the ASO. N-COM Pty Ltd indicated that this re-tuning would be done
at the same time as other broadcasters (at the Mount Campbell site 17 km SW of Morawa) re-tune/launch their digital services.
Moora: In order to keep all Toodyay, Northam and Dalwallinu services in Band V on blocks D and E, it is proposed that Moora services operate in block C.
Wongan Hills: Currently analog services for the Wongan Hills area are provided from two different transmitting sites: Wongan Hills; and Wongan Hills Town.
The Wongan Hills transmitter is located 7 km out of town and is of significantly higher power than the Wongan Hills Town transmitters. However two
commercial and two national (all four analog) services are transmitted in Band V from the Wongan Hills Town transmitter. Therefore, the preferred band for
the Wongan Hills area is Band V. However, due to the incompatibility of Wongan Hills services (transmitted from the higher power out-of-town site) with
Moora and Dalwallinu services, and the shortage of potentially available channels, and due to the fact that the Wongan Hills ERP is lower than those of the
Moora and Dalwallinu sites, Wongan Hills is proposed to have its digital channels in Band IV.
In addition, digital-digital co-channelling of Perth and Wongan Hills services is not possible due to severe interference from Perth into Wongan Hills.
Therefore, the current digital ABW7 service at Wongan Hills has to be moved to UHF because all eight VHF channels will be occupied in Perth or surrounding
areas (assuming a regional digital radio rollout). Therefore, the ABW7 digital service is proposed to be moved to channel 33 prior to the time that a channel 7
digital service in Perth commences operation. In addition, the proposed digital WOW29 cannot commence before the Perth SBS29 digital service moves to
Band III VHF. This, however, is not expected to raise a hard cutover issue since two immediately available, unconstrained commercial digital channels have
been provided at Wongan Hills (or Wongan Hills Town).
It is also noted that under the CTCS there is no obligation for broadcasters to provide terrestrial commercial services at Wongan Hills (or Wongan Hills Town).
In the case that the commercial broadcasters decide to provide digital terrestrial services at Wongan Hills, the Wongan Hills digital UA32 channel cannot be
used until the current Perth UA32 digital service moves to channel 10. However, the Perth UA32 service cannot move to channel 10 before the ASO in Perth
TV1 licence area.
28 | acma

A sequencing diagram showing the required steps before the proposed Wongan Hills Town WOW29 and UA32 digital service could start is provided in Figure
A5.1 in Appendix 5.
If no allowance is made for commercial digital terrestrial services at Wongan Hills (or Wongan Hills Town) and Dalwallinu, an improved channel allocation
arrangement for Wongan Hills, Wongan Hills Town and Dalwallinu could be considered.
Future digital radio services: Provision of future digital radio services at Geraldton is likely to use channels blocks within television channels 9 or 9A. Use
of channels 9 and 9A by low power (less than 100W ERP) digital television services at Mount Magnet and Meekatharra, which are respectively 317 and 442
km from the Geraldton transmitter site, are not expected to cause interference to (or receive interference from) future Geraldton digital radio services.
acma | 29

4.6 Area 5: Kalgoorlie/Esperance Region
Table 5: Channel arrangements for Area 5: Kalgoorlie/Esperance region before and after the proposed revision
Kalgoorlie: Due to a 1 MHz overlap between the operating Kalgoorlie WOW11 analog service and digital channel 10, the digital WOW service is proposed to
use channel 10. This provides a self-managing arrangement whereby the introduction of the WOW10 digital service will need to be coordinated with retuning
the WOW11 analog service.
Esperance: In order to keep all services in the same band, Esperance should be planned as a Band III site, with all six digital services chosen from available
channels in Band III.
Salmon Gums: Currently, Salmon Gums is a VHF Band III only site. However, Salmon Gums services will be incompatible with co-channel Esperance
services, which have been planned with six services in Band III. In order to avoid co-channelling with Esperance and make all six Salmon Gums channels
immediately available, Salmon Gums has been planned with all six digital channels in Band V.
Norseman: Norseman is currently a predominantly VHF site. However, Norseman should not be co-channelled with Kalgoorlie, which is proposed to have all
six services in VHF Band III, unless the antenna pattern at Kalgoorlie is changed. Therefore, all six Norseman services have been planned in Band V. Use of
Band V was driven by the fact that currently in Norseman one commercial and one national service operate on Band V channels above channel 51, which
suggests that viewers in Norseman are likely to have UHF Band V antennas.
30 | acma

Condingup/Howick: Condingup/Howick is currently predominately a VHF site with only SBS operating in Band V (SBS58). However, because it cannot be
co-channelled with Esperance, it has therefore been planned as a Band V site due to similar reasons as for Salmon Gums.
Ravensthorpe: The identified WAW8 digital channel is not available until ASO; this creates a hard cut-over question if the WAW8 analog retransmission
service is operating at the time the digital commercial services commence. However this can be avoided by changing the allotment for the WAW service to
channel 9 or by switching it off (a DOLMA would not be required).
Due to a 1 MHz overlap between the operating non-standard Ravensthorpe ABW11 analog service and digital channel 10, the digital ABW service is
proposed to use channel 10. This provides a self-managing arrangement whereby the introduction of the ABW10 digital service will need to be coordinated
with retuning the ABW11 analog service.
Future digital radio services: Provision of future digital radio services in south-western parts of Western Australia is expected to use channels blocks within
television channels 9 or 9A. Given the large distances between Kalgoorlie and Esperance and likely radio transmission sites in south-western Western
Australia, use of channels 9 and 9A for operating digital television services at Kalgoorlie and Esperance is not expected to cause interference to (or receive
interference from) future digital radio services in the south-western part of Western Australia. Channels 6 and 10 could be considered for T-DAB services at
Esperance. Channel 8 could be considered for T-DAB services at Kalgoorlie and channel 6 may also be available depending on the ability to co-channel with
the Norseman ABW6 digital service.

4.7 Area 6: Pilbara Region
Table 6: Channel arrangements for Area 6: Pilbara region before and after the proposed revision
Newman: Currently in Newman there are six operating channels (ABC, SBS, WAW and WOW analog services and ABC and SBS digital services). All of
these services are in VHF Band III. Therefore, two channels have been made available for commercial broadcasters. This, however, is expected to raise a
hard cutover issue requiring a DOLMA as three immediately available, unconstrained commercial digital channels are required at Newman.
Pannawonica: Currently in Pannawonica there are five operating channels (ABC, SBS, WAW and WOW analog services and an ABC digital service). All of
these services are in VHF Band III. Therefore, one channel has been made available for commercial broadcasters and one for SBS. This, however, is not
expected to raise a hard cutover issue since one immediately available, unconstrained commercial digital channels have been provided at Pannawonica.
However, due to a 1 MHz overlap between the operating non-standard Pannawonica ABW11 analog service and digital channel 10, the proposed digital
SBS10 service cannot start operating before the analog ABW11 service is re-tuned to the standard frequency or switched off. This may raise a hard cutover
issue since there is a current SBS analog retransmission service operating at Pannawonica.
32 | acma

Paraburdoo: Due to a non-standard frequency arrangement for the WAW11 analog service, there is an overlap of about 1 MHz between standard channel 10
and the operating non-standard channel 11 at Paraburdoo. Therefore, the digital WAW service is proposed to use channel 10. This provides a selfmanaging
arrangement whereby the introduction of the WAW10 digital service will need to be coordinated with retuning the WAW11 analog service. T-DAB
ERP may be constrained by
Tom Price: Due to a 1 MHz overlap between the operating non-standard Tom Price ABW10 analog service and digital channel 9A, the proposed digital
WDW9A service cannot start operating until the analog ABW10 service is re-tuned to the standard frequency or switched off. This, however, is not expected
to raise a hard cutover issue since two immediately available, unconstrained commercial digital channels have been provided at Tom Price.
Future digital radio services: Potential future digital radio services in this region are expected to be delivered using relatively low powered (less than 1 kW
ERP) transmitters that would probably be co-sited with television broadcast services. When taken together with the large distances between most of these
sites, it was not considered necessary to define a common sub-band for potential future digital radio services. It is however noted that at each site two
(though not always the same two) television channels are unused which provides, in most cases, capacity for future digital radio services when and if they are
required.

4.8 Area 7: Kimberley Region
Table 7: Channel arrangements for Area 6: Kimberley region before and after the proposed revision
Broome: In addition to two national and three commercial services, an analog HPON service operates in Broome. As Broome is currently a predominantly
VHF site with three analog and two digital services currently licensed/operating in Band III, Broome should be planned as a purely VHF site. However, there
are no currently available VHF channels for a possible digital HPON service to operate in Band III, so the possible digital HPON will need to continue
operating in UHF. If required, the HPON service could be assigned a VHF channel that would become available after the analog switchover. This would still
leave one vacant television channel that could be used for provision of future Band III digital radio services.
Due to a non-standard frequency arrangement for the WAW11analog service, there is an overlap of about 1 MHz between the standard digital channel 10
service and the operating WAW11 analog service at Broome. This provides a self-managing arrangement whereby the introduction of the WAW10 digital
service will need to be coordinated with retuning the WAW11 analog service.
Derby: Due to the number of currently operating analog VHF Band III services, and the desire to retain Derby as a VHF only site, it is not possible to provide
five digital channels that will be immediately available. Therefore, two channels have been made available for commercial broadcasters. This, however, is

expected to raise a hard cutover issue requiring a DOLMA as three unconstrained commercial digital channels are required at Derby. In addition, due to a
non-standard frequency arrangement for the WAW11 analog service, there is an overlap of about 1 MHz between the standard digital channel 10 and the
operating WAW11 analog service at Derby. This provides a self-managing arrangement whereby the introduction of the WAW10 digital service will need to
be coordinated with retuning the WAW11 analog service.
Wyndham: Due to a non-standard frequency arrangement for the ABW10 analog service, there is an overlap of about 1 MHz between the standard digital
channel 9A and the operating ABW10 analog service 10 at Wyndham. Therefore, the digital WDW service that is proposed to use channel 9A, cannot start
operating before the analog ABW10 service is re-tuned to the standard frequency or switched off.
Future digital radio services: Potential future digital radio services in this region are expected to be delivered using relatively low powered (less than 1 kW
ERP) transmitters that would probably be co-sited with television broadcast services. When taken together with the large distances between most of these
sites, it was not considered necessary to define a common sub-band for potential future digital radio services. It is however noted that at each site one or two
(though not always the same channel(s)) television channels are unused which provides capacity for future digital radio services when and if they are
required.

4.9 Area 8: Remainder of Western Australia
Table 8: Channel arrangements for Area 8: Remainder of WA before and after the proposed revision
Carnarvon: Carnarvon is a pure VHF site. Currently in Carnarvon there are six operating channels in Band III. The remaining two VHF channels are, in the
current DCP, assigned to WAW and WDW. Therefore, two channels have been made available for commercial broadcasters. This, however, is expected to
raise a hard cutover issue requiring a DOLMA as three unconstrained commercial digital channels are required at Carnarvon. In addition, due to a nonstandard
frequency arrangement for the WAW10 analog service, there is an overlap of about 1 MHz between the standard digital channel 9A and the
operating WAW10 analog service at Carnarvon. Therefore, the digital WAW service is proposed to use channel 7.
Exmouth: Exmouth is a purely VHF site with six operating channels in Band III. Therefore, two channels have been made available for commercial
broadcasters. This, however, is expected to raise a hard cutover issue requiring a DOLMA as three unconstrained commercial digital channels are required
at Exmouth. In addition, due to a non-standard frequency arrangement for the WAW11 analog service, there is an overlap of about 1 MHz between the
standard digital channel 10 and the operating WAW11 analog service at Wyndham. Therefore, the digital WAW service is proposed to use channel 6. .
Future digital radio services: Potential future digital radio services in this region are expected to be delivered using relatively low powered (less than 1 kW

5. Impact on existing services
5.1 Summary of Implications of block plan at commercial rollout
The following sections summarise the key changes that would be required if remote and
regional WA digital channels were to be implemented using a block planning approach at the
time of the commercial rollout. Note populations are, in most cases, the population best
served by the relevant transmitter. It is not necessarily the population of the particular town.
Details of the changes are in section 5.2.
5.1.1 Digital channel changes
The following channel changes are proposed to be implemented prior to analog switchover
and general restacking of operating services to facilitate the commencement of services at
this or nearby sites.
� Central Agricultural SBS48 to 43 to free 48 for digital repeater sites (pop. 16 000)
� Southern Agricultural SBS29 to 10 to provide all digitals in VHF (pop. 32 000)
� Albany ABW8 to 43 to allow Southern Agricultural WOW8 digital (pop. 9 700)
� Morawa SBS40 (retransmission) to 33 to allow Geraldton GTW40 digital (pop. 1 300)
� Total population potentially affected by digital channel changes = 59 000.
5.1.2 Analog channel changes
The analog services listed below should change to an alternative channel prior to analog
switchover:
� Bunbury WOW39 to 40 to allow Bunbury WOW39 digital (pop. 120 000)
� Albany WOW43 to 52 to allow Albany ABW43 digital. (pop. 9 700)
� Albany SSW10 to 55 to allow Southern Agricultural SBS10 digital. (pop. 9 700)
� Katanning SSW10 to 9A to allow Southern Agricultural SBS10 digital. (pop. 4 600)
� Central Agricultural SSW50 to 52 to free 50 for repeater sites (pop. 16 000). This
change may not be required to ASO depending on channel assignments at affected
sites; and decisions on whether the ABC and SBS will move to final channels early or
after ASO.
� Dampier WAW32 to 41 to allow WOW32 digital (pop. 1 200). Alternatively a DOLMA
could be considered.
� Total population potentially affected by analog channel changes = 151 500.
The analog services listed below may be required to change to an alternative channel prior to
analog switchover depending on final channel assignments and spectrum demand:
� Eneabba SBS40 (retransmission) to 52 (pop. 350) to allow Geraldton GTW40 digital.
� Kellerberrin ABW41 (retransmission) to 53 (pop.

� Derby WAW11 (likely DOLMA and therefore may not be required to change)
� Halls Creek WOW11
� Kalgoorlie WOW11
� Koolyanobbing ABW11 (likely DOLMA and therefore may not be required to change)
� Meekatharra WOW11
� Mount Magnet WOW10
� Pannawonica ABW11 (likely DOLMA and therefore may not be required to change)
In practice the population affected by such frequency changes is very small as almost all
analog receivers will “capture” the frequency shift without any viewer interaction.
5.1.3 Analog interference
In some cases new digital services may cause interference to the reception of some analog
services. This interference would appear to viewers as “snowy” analog reception. In some
cases (see 5.1.2) it would be appropriate to change the channel of the analog service. In
other cases, a change to the analog service may cause more disruption to a larger number of
people than is arguably warranted given the relatively short period to ASO. Depending on the
situation, it may be preferable to encourage viewers who do suffer unacceptable interference
to their analog reception to switch to digital early.
� Bunbury SBS33 analog service is predicted to receive interference from a Wagin
SSW33 digital service affecting an estimated population of 1 500 (770 dwellings).
� Wagin ABW6 and SSW8 analog services are predicted to receive interference from
Southern Agricultural SSW6 and WOW8 digital services affecting an estimated
population of 3 000 (1 600 dwellings).
� Geraldton SBS29 and WOW32 analog services are predicted to receive interference
from Morawa GTW29 and GDW32 digital services affecting an estimated population
of approximately 100 (50 dwellings).
� Toodyay ABW40 and TVW43 analog services in the Perth licence area, are predicted
to receive interference from Central Agricultural SSW40 and SBS43 digital services
affecting an estimated population of approximately 750 (350 households).
� Total population in areas affected by analog interference = 5 350.
Many potentially affected viewers will already have switched to digital and no longer be
relying on the analog transmissions for some services. When the commercial services
commence at Bunbury, Wagin and Geraldton affected viewers could switch to digital for all
reception. To avoid viewer confusion there needs to be a careful communication campaign for
potentially affected viewers who, arguably, will have an early analog switchover.
The analog services discussed above that might suffer interference from new digital services,
might also cause some interference to the new digital services. Affected viewers will need to
continue watching the analog service until analog switch-off. The extent of this interference
has not been studied in detail, but is expected to be less severe than the interference to the
analog services.
5.1.4 Rollout timing issues
The above summary and the analysis in 5.2 indicate that there are a number of rollout timing
issues where it would be sensible for particular services to commence before other services.
� The Bunbury digital commercial services should commence well before the Wagin
digital commercial services to encourage digital take up around Bunbury as the
Wagin SSW33 digital service may cause interfere to the Bunbury SBS33 analog
service.
� The Wagin digital commercial services should commence well before the Southern
Agricultural digital commercial services to encourage digital take up around Wagin as
the Southern Agricultural SSW6 and WOW8 digital services may cause interfere to
the Wagin SSW6 and ABW8 analog service.
38 | acma

� The Geraldton digital commercial services should commence well before the Morawa
digital commercial services to encourage digital take up around Geraldton as the
Morawa GTW29 and GDW32 digital services may cause interfere to the Geraldton
SBS29 and WOW32 analog service.
� Commercial digital services at Perenjori, Carnamah, and Mingenew should
commence before or at the same time as Morawa as viewers in these areas may be
receiving the currently operating higher power Morawa ABC service. Commencing
before or at the same time will encourage viewers in these towns to optimise their
reception equipment for the local services rather than, inadvertently, rely on the
weaker Morawa commercial services. Note that the Morawa ABW7 digital service will
need to move to UHF channel 28 and, to provide adequate coverage of Perenjori,
Carnamah and Mingenew, the ABC is encouraged to establish local digital
transmissions matching the other services for these towns.
5.1.5 Early analog switchover
There are a number of areas in remote and regional WA which have only VHF analog
services with no current UHF transmission or reception infrastructure. In some of these areas
it will be possible to implement all national and commercial digital services in the VHF band
without affecting the analog services. In some cases, though, this will not be possible. Rather
than implementing short term UHF analog transmissions, it would be preferable to turn off the
analog services at these sites early and have a “hard” switchover of analog and digital
services.
To facilitate such changes the area would need to be determined to be a Digital Only Local
Market Area (DOLMA) and all analog transmissions in that area would need to cease at a
determined date.
This report has identified the following sites where DOLMAs are likely to be required:
� Carnarvon (pop. 5 300). ABW7 and SBS12 block two digital services.
� Derby (pop. 3 200). WOW6 blocks one digital service.
� Exmouth (pop. 1 900). WOW6 and WAW11 block two digital services.
� Koolyanobbing (pop. 260). WOW6 and possibly ABW11 block two digital services.
� Newman (pop. 4 200). ABW7 and WOW10 block two digital services.
� Pannawonica (pop. 690). WOW6 and WAW8 block two digital services.
� Total population in areas affected by DOLMAs = 15 500.
As mentioned in 5.1.2, there could also be a case made for a DOLMA at Dampier (pop 1 200)
rather than a consequential analog channel change.
DOLMAs are only required for the early switchover of digital services licensed by
broadcasters and covered by the conversion schemes. Analog retransmission services can
close prior to analog switchover without requiring a DOLMA.

Appendix 1: Analysis Methodology
A1.1 Description of analysis and block selection process
A1.1.1 Analysis procedure
1. Identify sites to be included in the restacking process.
2. All sites included in this study are to be allotted a set of six digital channels, i.e. three
commercial, two national and one unassigned channel, except for the overlap site of
Mandurah and Broome which has an HPON service. Where possible, the six digital
channels are allotted in blocks as defined below.

Block C 34 35 36 37 38 39
Block D 40 41 42 43 44 45
Block E 46 47 48 49 50 51
3. Site-to-site interference compatibility analyses are performed for all sites that might
potentially interfere with each other. The site-to-site compatibility analysis has been
done using the LS Telcom CHIRplus software. The analysis was performed to
identify the sites that cannot be co-channelled due to unacceptable levels of
interference.
4. The site-to-site compatibility analysis was performed for each of the Areas.
5. For Areas which have a fairly high density of the transmitters, interference studies
were performed for each transmitter over the whole area. In Areas which have a
lower density of transmitters, site-to-site interference studies were performed on a
case-by-case basis.
6. Initial compatibility analyses were performed using the L&S VHF/UHF (non-tuneable)
propagation model (because its computational time is quicker than the other
propagation models). All results that showed compatibility after initial analysis with
the L&S VHF/UHF propagation model were rechecked using the Rec. ITU-R P.1546-
1 propagation model. However, in cases where results were either not clearly
compatible or clearly incompatible, more detailed analysis was performed using other
propagation models, i.e. the CRC Predict and Rec. ITU-R P.1812 models.
7. Matrices showing the results of the compatibility studies are presented in Tables in
Appendix 4. Those tables provide a summary assessment of the practicality, or
otherwise, of co-channelling various site pairs.
A1.1.2 Data file setup and assumptions
Polarisations, antenna patterns and effective radiated powers (ERPs) used in the simulation
studies were assumed to be the same as those of currently planned/operating digital services.
Where available, the transmitting antenna horizontal radiation pattern (HRP) data supplied by
broadcasters during the implementation plan process was used.
In this study, channel 50 was selected as a representative worst-case Band V channel for use
in compatibility analyses. Transmitter data file entries were adjusted to create notional digital
services (and analog where appropriate) on channel 50 (or channel 9 in the case of VHF
studies). When an existing VHF or Band IV service is changed to channel 50, its ERP level is
acma | 49

adjusted by +10 or +4 dB respectively. These changes are consistent with principles applied
in developing the current DCPs.
In cases where several planned and/or operating digital services at a site (or nearby sites
intended to serve the same general area) have different ERPs or antenna patterns, the
highest ERP was used.
In modelling the digital conversion of retransmission services it was assumed that those
services would operate with identical antenna heights and HRP antenna patterns but with
digital ERP levels 6 dB lower than the current analog ERP level.
To reduce the total number and time of analyses to be performed, where it was considered
that certain services were unlikely to cause interference to a particular wanted service, the
interference study was performed with several interferers simultaneously. (If this multiple
interferer study shows no interference then it can be deduced that all of the potential
interferers are compatible with the wanted service without the need for individual studies).
For the wanted signal the E(50,50) 12 field strength was calculated. For digital to digital
interfering signals (and analog-to-digital interfering signals) the E(50,1) field strength was
calculated, and for digital to analog interfering signals the E(50,10) field strength is calculated.
In accordance with the current Digital Terrestrial Television Broadcasting (DTTB) planning
handbook 13 , Band V digital television services are protected either within a rural contour
defined by a minimum required field strength of 54 dB�V/m, or within a suburban contour
defined by a minimum required digital television field strength of 67 dB�V/m.
An initial cull of potential interferers was performed based on a protection ratio threshold
between wanted and interfering services of 26 dB 14 . Therefore, for the services that require
protection within the rural 54 dB�V/m contour, the interfering signal should be no more than
28 dB�V/m. If the field strength of a potentially interfering service was below 28 dB�V/m
everywhere within the rural coverage area of the wanted service, this interferer was not
studied further.
If a service was found to suffer potential interference within its coverage area, further checks
were then made to determine if the affected area(s) was better served by an alternative
service(s). If so, it was assumed that the interference area(s) could be “masked” by the
alternative service(s). In these situations, the interference is not considered to prevent cochannelling
the wanted service with the service(s) causing the interference in the masked
area(s). The masking is performed using the CHIRplus Best Server analysis function to
determine which area is best served by which transmitter.
A1.1.3 Channel planning approach and process
Changes to licensed/operating digital channels should be minimised as much as possible.
However, in order to optimize the overall channel allocation solutions as a block configuration
changes to currently licensed services may be proposed.
Two 7 MHz channels in VHF Band III have been left clear for potential future planning of
regional digital radio services.
In the channel planning process, channels were planned, where practical, according to the
following principles:
� ERP levels of restacked services should be planned on the same basis as the originally
planned DCP services;
� All channels at a site should be planned to be within the same block;
12 E(x,y) denotes field strength value that is equalled (or exceeded) for x % of locations and y % of time, e.g.
E(50,50) is field strength value that is achieved for at least 50% of locations and 50% of the time.
13 For VHF studies the applicable minimum field strength values are 44 and 57 dBuV/m.
14 The protection ratio between the wanted and interfering services of at least 20 dB plus a 6 dB margin.
50 | acma

� Where channels cannot be placed in the same block, then channels should be assigned
as near as possible to the block;
� Blocks should be planned to be within the band that is currently the main band for that
site (e.g. if a site was identified as a Band V site in the current DCP, the intention was to
preserve all services within Band V);
� Channel blocks should be planned such that they do not fall outside the likely minimum
bandwidth of existing viewer antennas;
� If possible, channel 51 should be avoided at high power sites.
� To minimise the possibility of interference to or from digital radio services, and to allow a
more spectrum efficient digital radio implementation, avoid use of channels 9 and 9A in
metropolitan and regional areas.
A1.1.4 Channel assignment principles
The following principles were used in assigning services to particular channels in a block
configuration:
1. Because a key objective of this study is to identify final digital channel blocks that can be
implemented prior to analog switchover, where a site has one or more channels that
cannot be available until after analog switchover, assign the constrained channels as
follows:
a. If there is only one constrained channel, assign it to the unassigned service (since it
is considered unlikely that the unassigned service will be used prior to analog
switchover at any site except for Perth)
b. If there is more than one constrained channel but one or more of the potential analog
services at the site are not operating then the constrained channels can be assigned
to the services associated to the not-operating analog services (and the unassigned
service).
c. If there is more than one constrained channel and if national (or commercial) digital
services already operate at the site on channels different from their final channels
(e.g. on channels above channel 51), the relevant national (or commercial) services
may be assigned constrained final channels, since an analog-digital simulcast can
occur and there will be no hard cut-over concerns since viewers will be able to watch
the current digital channels. (There is of course a requirement for a digital-digital
transition at some time after analog switchover).
d. If that is not possible, one or two of the three commercial digital allocations may be
assigned constrained channels. By default the applicable GDW, SDW, VDW or
WDW service has been given priority over the other two commercial digital services
for access to unconstrained channels. However, in respect of hard cutover issues the
following consideration should be noted.
e. At sites where only two unconstrained channels are immediately available for
commercial services there should be no hard cutover issue because the
“unconstrained” digital channels can be matched with the services of the two currently
operating analog commercial services. (However this may require minor changes to
the default channel assignments shown in the channel plan tables).
acma | 51

2. To assist in managing adjacent channel interference, assign digital channels on channel
adjacent to currently operating analog services of the same network 15
3. To maximise the opportunity for broadcasters to re-use existing antenna and combiner
infrastructure, any re-used analog channels at a site should be assigned to the same
broadcaster (noting however that this may be contrary to allowing a pre-analog
switchover simulcast);
4. To assist in managing marginal co-channel interference situations (if any) and to facilitate
broadcaster management of SFNs where they are necessary such cases should be
assigned to the same broadcaster at all affected sites;
5. Where other criteria do not apply, assign three commercial services next to each other;
6. Where practical assign ABC and SBS services next to each other;
7. If channel 51 is used, the unassigned service should be assigned to channel 51;
8. Where principles are in conflict, give more weight to the assignments at the greater
population (or higher power site) coverage site;
9. If no other criterion applies use same channel order as existing analog services.
A1.2 Calculation Parameters
The key transmitter site parameters used in the interference calculations are summarised in
Table A3.1 of Appendix 3. The table is an edited version of an extract from the CHIRplus
software. All transmitters were adjusted to use channel 50. In a small number of cases VHF
Band III calculations were also performed. In those cases assessments were performed
using channel 9 as a default channel. (The Band III data used are shown as a second entry
in the table). For broadcaster sites Horizontal Radiation Pattern (HRP) data was obtained
using either current DCP envelope patterns or, when available, Implementation Plan (IP) data
as indicated in Table A3.1. For retransmission sites the envelope pattern recorded in
RADCOM was used, again this is recorded in Table A3.1. Vertical Radiation Pattern (VRP)
data was generally not available, and generally speaking VRPs have little impact on
interference studies, therefore VRP pattern data was not used in this study.
The Shuttle Radar Topography Mission 3 second Digital Elevation Model (SRTM –v2 DEM
3s) was used as the calculation raster. Receiver polarisation was set to “matched”, and the
reference receiver height was set at 10 m. In the Calculation window under Options field,
only “Wanted/Steady”, “Interfering/Tropo”, and “Ignore Site Height of TX” 16 options were
ticked. An example of the calculation window setup is shown in Figure A1.
For the calculation of the field strengths, the L&S VHF/UHF (non-tuneable) propagation model
was used in the first instance. In cases where the interference result was neither a clear
“pass” nor a clear “fail”, the CRC Predict propagation model was used as the second step in
the interference study. In the cases where the two propagation models produced significantly
different results, analyses using the Rec. ITU-R P.1812 and 1546-1 propagation models were
also performed.
15 At a number of pure VHF sites in remote and regional WA licence areas, due to analog services on channel 10
and 11 operating on “old raster” channels of 208-215 and 215-222 MHz respectively, a channel which would
otherwise be clear for use by a digital service may not be immediately available. Therefore, at those sites the
digital channel was typically assigned to the same licensee as the operator of the “old raster” analog channel.
This provides a self-managing arrangement whereby the introduction of the digital service will need to be
coordinated with retuning the analog service.
16 This has the effect of instructing the software to extract the transmitter site height values from the SRTM – v2 3
sec DEM, which ensures that the site heights used in the calculation are aligned with the heights and shape of
the DEM that was used in the calculations. Details of the transmitter site height values used in the calculations
are given in the “Elev.” column of Annex 2.

Figure A1: Typical appearance of the Calculation window in the CHIRplus software
Interference analysis was performed using Network Processor tool in the CHIRplus software.
The following parameters were used in the analysis; the minimum equivalent field strength
was set to 54 dB�V/m, which is obtained by setting the minimum median field strength to
49.369 dB�V/m. Other parameters were set as following; location probability: 80%, standard
deviation: 5.5 dB, bandwidth: 7 MHz, receiver conditions – fixed, receiver synchronization
method – main focus. The shape of the weighting function in the guard interval was set by
selecting symmetrical DVB model (DVB Sym). System variant was set to C2: 64 QAM | 2/3,
and the designator field G: 8k | 1/8 17 . These planning parameters were selected according to
the DTTB planning handbook.
17 However no SFNs are being proposed in the analysis, so this assumption will have no influence on the outcome
of studies described in this report.
acma | 53

Figure A2: Typical appearance of the Calculation Parameters window in the Network
Processor tool in the CHIRplus software.
It should be observed that in the analysis with a single wanted service, the wanted summation
method is irrelevant. For a limited number of cases, where multiple interference studies were
performed in order to more quickly exclude a number of sites as potential interferers, a
combined approach using more than one potentially interfering transmitter was applied. In
these cases, the power sum method was used for the interfering signals summation.

Table A3.2: Key parameters for analog sites used in the interference analysis. This data has been extracted from the CHIRplus software.
The simulation parameters (including channels and corresponding ERP levels) were adjusted for a limited number of interference studies from digital into
already existing analog services. These studies are:
� Bunbury digital into Nannup analog (channel 35)
� Central Agricultural digital into Dalwallinu analog (channel 46), and
� Geraldton digital into Eneabba analog (channel 40).
Since in these cases the particular services may be affected, the actual parameters were used in each study, rather than the default channel 50 assumption.

From Perth
(1) Using CRC Predict, significant interference predicted to occur within town, although Perth and Leeman digital services are currently operating cochannelled
on channel 6. If interference is a problem then increasing Leeman ERP to 150 W should move interference to less populated areas. Next
nearest services using block A is Yalgoo and Kalbarri.
(2) Wider coverage ABC service only, other services have low power services covering the town of Southern Cross. The total population predicted to be
covered is 1144. When using the CRC Predict propagation model, interference from co-channelled Perth VHF services, inside the UC/L of Marvel
Loch, could potentially affect a population of 12 out of 99. The Southern Cross UC/L, with a population of 710 is unaffected. Outside the UC/L‟s a
population of 7 is predicted to have interference. If an ABC service was implemented at Southern Cross Town, then the Southern Cross ABC service
would only best serve a population 11 people, of which only one is predicted to suffer interference. This 1 person is not inside a UC/L.

(3) Interference on outer fringe of coverage potentially affecting 2 people outside the UC/L. Total population covered 517. (CRC Predict propagation
model).
(4) Assuming a VHF option at Southern Agricultural, when using CRC Predict propagation model, co-channel Interference from Perth at the edge of
coverage is predicted to potentially affect a population of 4137 out of 47314. 2910 of this potentially affected population are in UC/Ls (ie towns). If a
best server plot is used to remove areas not best served by Southern Agricultural then the potentially affected population reduces to 950, with 347 of
these in UC/Ls, primarily Gnowangerup, which has analog retransmissions. Southern Agricultural best serves 34816 people. Converting
Gnowangerup would remove up to 334 people out of 347 people potentially affected in UCL/s. Alternatively, viewers in Gnowangerup would be able
to access VAST, possibly with the satellite subsidy. Alternative services for viewers affected by co-channel interference from Perth would be the
Wagin, Katanning, Kojonup, Manjimup, Pemberton and Albany services.
From Roleystone
(1) Interference does occur to the Mandurah services in populated areas that are best served and entitled to be served by Mandurah. For the metro
services 250 people out of 25000 people may be potentially affected by interference from Roleystone. Most of these people are located along the
Western side of Harvey Estuary in towns such as Dawesville and Bouvard. For the regional services 670 people may be potentially affected out of
46000 people. Again most of these people are located along the Western side of Harvey Estuary in towns such as Dawesville and Bouvard. For
national services, 140 people out of 18500 may be potentially affected. Again most of these people are located along the Western side of Harvey
Estuary in towns such as Dawesville and Bouvard. (CRC Predict propagation model).
(2) Small amount of interference immediately around Roleystone transmitter potentially affecting 62 people who would be able to receive either
Roleystone or Perth. (CRC Predict propagation model).
From Mandurah
(1) Population analysis indicates very few people potentially affected after masking with Perth using a Max server, suburban coverage. (CRC Predict
propagation model).
From Central Agricultural
(1) Population analysis indicates very few people potentially affected after masking with Perth using a Max server, suburban coverage. (CRC Predict
propagation model).
(2) Moderate interference depending on which propagation model is used. When using the 1546-1 propagation model depending on whether you mask
Mandurah with Perth or Bunbury only between 29 and 462 people may be potentially affected. When using the CRC predict propagation model the
population increases significantly to between 7500 and 13000 people may be potentially affected. This could be a concern however due to the
relatively flat terrain around the target area the 1456-1 propagation model is probably more relevant in this case.
(3) Moderate interference however mostly in unpopulated areas. If masked with Perth as an alternative service and restricted to within the Perth licence
area, then 58 people out of about 1,200 people may be potentially affected. If limited to Suburban coverage, minor interference. Population analysis
indicates less than 10 people potentially affected out of about 1100 people if masked with Perth and the Perth licence area. (CRC Predict
propagation model).
From Lancelin
(1) Population analysis indicates very few people potentially. (CRC Predict propagation model).

From Northam
(1) Minor interference at edge of coverage. Population analysis indicates 38 people out of 1600 best served by Toodyay may be potentially affected.
(CRC Predict propagation model).
From Dalwallinu
(1) Minor interference at edge of coverage. Population analysis indicates 71 people out of 1600 best served by Toodyay may be potentially affected.
(CRC Predict propagation model).
From Toodyay
(1) Minor interference at edge of Suburban coverage. No interference after masking with Central Agricultural. (CRC Predict propagation model).
From Wagin
(1) Minor interference at edge of coverage. When using the 1546-1 propagation model depending on whether you mask Mandurah with Perth or
Bunbury only approximately 10 people may be potentially affected. When using the CRC predict propagation model between 400 and 1100 people
may be potentially affected. However due to the relatively flat terrain around the target area the 1456-1 propagation model is probably more relevant
in this case.
From Geraldton
(1) Moderate interference. When using the 1546-1 propagation model, population analysis indicates only 14 people are affected out of 1100. However
when using the CRC propagation model up to 200 people may be potentially affected out of 1200 after removing people outside the Perth LA. This is
reduced to 170 if people who are best served by Perth are removed and again reduced down to 90 people when people who receive less than
suburban level coverage are removed. Also half of the population in the small town of Ledge point may be potentially affected by interference from
Geraldton population of about 160 people. If masked to Suburban level, minor interference occurs at the edge of Suburban coverage. About 90
people may be potentially affected out of 1100 people after masking with Perth coverage and the Perth licence area.
From Perth East/City
(1) Minor interference at edge of coverage. (1546-1 propagation model).
From Maryville
(1) Minor Interference at edge of coverage. (1546-1 propagation model).
From Leeman +10dB
(1) Minor interference at fringe of coverage Population analysis indicates 118 people may be potentially affected. If masked with best server plot only 73
people may be potentially affected, 69 are inside the Perth licence area. (CRC Predict propagation model).
From Southern Cross
(2) Shows negligible interference at the far edge of coverage with population analysis showing only 59 people potentially affecting. (CRC Predict
propagation model).
86 | acma

From Southern Agricultural
(4) Interference at the southern edge of Perth coverage, population analysis indicates 3145 people may be potentially affected. However, after masking
with a best server plot, it reduces to 1752 people and reduces to 604 people when restricted to the Perth LA. Most of these people are down the coast
near Mandurah but don‟t get Mandurah coverage and to the east of Perth near Bakers Hill. (CRC Predict propagation model).

Appendix 5: Sequence of events to
commence digital services
Table A5.1 below shows the sequence of re-tuning events that need to occur at sites to
minimise interference before digital services can operate to the proposed channel block plan.
With exception to the 2014 target cut off date, all time-lines shown in Table A51 are
relative only and should not be interpreted as a prescriptive requirement.
