MAJOR EMPLACEMENT AND
MAINTENANCE HAZARDS
The precautions given in 1 and 2 below must be observed to
prevent injury or death to personnel:
1. Installation and assembly hazards associated with the
equipment are as follows:
a. After performing maintenance ensure the doors
and covers are installed prior to attempting to
return the equipment to service.
b. On all electrolytic capacitors, make sure terminal
polarity markings [positive (+) and negative (-)]
are observed when connecting capacitors to ± dc
buses.
2. While performing maintenance on the equipment,
observe the following precautions:
SAFETY SUMMARY
2. Electrostatic handling of MaS devices is of prime
importance. Static electricity is always present in any
work environment. It is generated when ever two
different materials are rubbed together. A person
walking across the floor can generate a charge of
thousands of volts. A person working at a bench,
sliding around on a stool, or rubbing his arms on the
work bench can develop a high static potential. For
preventing damage to devices due to ESD, use the
following precautions:
a. Table tops or work areas should be covered with
grounded conductive tops. Test areas should
have conductive floor mats.
b. Tools and test equipment used in protected work
areas shall be properly grounded. Ensure that
soldering-iron tips are grounded. If plastic
handled tools must be used, they shall be treated
with a topical antistat.
X
a. Maintenance of equipment shall not be
performed when thunderstorms and lightning are
imminent or in progress.
c. Devices, or circuit cards with devices, should not
be inserted into or removed from circuits with
the power on because transient voltages may
cause permanent damage.
b. When performing maintenance on the equipment
make sure all ac power to the unit is removed.
STATIC SENSITIVE DEVICES
d. Use a conductive wrist strap when removing a
circuit card containing MaS/CMOS devices
from a card cage or when removing a device
from a circuit card.
There are some circuits throughout the equipment using
metal-oxide-semiconductor (MaS) and complementary
MOS (CMOS) integrated circuits. This requires stringent
attention to handling techniques due to the sensitivity to
static electricity. The following paragraphs outline the
procedures to use when handling MaS or CMOS devices.
1. Electrostatic discharge hazards in MaS/CMOS
devices are prevalent. Such damage can be produced
by Electrostatic Discharge (ESD) due to improper
handling or installation. All MaS/CMOS devices are
susceptible to damage by the discharge of electrostatic
energy between any two pins. This sensitivity to static
charge is due to the fact that gate input capacitance (5
picofarads typical) in parallel with an extremely high
input resistance (10 12 ohms typical) lends itself to a
high input impedance and hence readily builds up the
electrostatic charges.
3.
e. The devices are to be stored or transported in
static shielding bags, anti-static rails, or
conductive foam.
ESD grounding is critical to safe handling of ESD
sensitive devices. Earth ground rods for ESD
protection shall be solid copper or copper jacketed
steel and shall be driven six to eight feet into the earth
beyond the work area floor slab with approximately
six inches exposed for making connection. Dry soil
conditions may require a copper sulfate drip.
Electrical grounds shall be isolated from static
grounds.
Water pipes offer convenient grounds; however, they
may not be connected to earth ground. These
techniques are for minimizing the difference of
potential between separate grounds, and not for
reducing the ohmic resistance to earth.

THIS TRANSMITTER ARE DEADLY TO
HUMAN LIFE.
1-1. INTRODUCTION
The 816R-5C transmitter operates in the FM broadcast
range (88-108 1;lHz) with an RF output power of 35 kW.
Reduced power is available by tap changes ofthe plate and
screen transformer to meet customer requirements. When
the exciter receives input from the optional stereo generator
and SCA generator, the transmitter provides continuous
monaural, stereophonic, and SCA (subsidiary
communication authorization) frequency-modulated
programs.
1-2. FUNCTIONAL DESCRIPTION
The transmitter consists of an exciter, a solid-state driver,
and a power amplifier. The output ofthe exciter is applied
to the driver. The driver consists of two 400-watt modules
combined. The input to the driver is amplified to
I approximately 500 watts and applied to the power amplifier
that contains one
4CX20,000E tube operated class C. The output of the power
amplifier is applied to a 50-ohm unbalanced load. Power
control circuits monitor the RF output power level. When a
change in output power is detected, these circuits change the
plate voltage to compensate. Other control circuits within
the transmitter monitor reflected power, forward power,
operating voltage, air pressure and exhaust air temperature
within the power amplifier section. They protect the
transmitter by removing power when excessive currents,
VSWR, loss of air pressure, or excessive air exhaust
temperature occur.
1-3. PHYSICAL DESCRIPTION
The transmitter is housed in a unistrut cabinet that contains
all transmitter components, except the plate transformer
assembly, A14. The plate transformer is in a separate
enclosure. Refer to Figure 1-1. The transmitter contains
three sections. The section on the left in Figure 1-1 contains
the power amplifier. The center section houses the control
panel, control circuits, exciter, and driver circuits. The
section on the right contains the power supplies, the circuit
breakers, and fuse panel.

INSTALLATION
SECTION 2 - INSTALLATION
2-1. PRE-INSTALLATION INFORMATION
The transmitter requires three phase 200 to 250 volts, 50 or
60 Hz, AC primary power ofeither Wye or closed Delta
configuration. Line-to-line balance must be within five
percent both for voltage and phase.
Refer to Figure 2-1 for location ofair ports, wire ports, and
cabinet dimensions. The transmitter should be located to
allow access to front and rear.
2-1.1 AC Power.
Figure 2-1 shows the location ofthe openings in the top and
floor ofthe transmitter that can be used to bring the power
cables into the transmitter. Power cables may be brought
through either a two-inch (5 cm) knockout in the top ofthe
cabinet or through a two-inch round opening in the floor of
the transmitter. The size ofthe power wiring is determined
by local electrical code and good engineering practice. In no
ca~e should the wiring be smaller than number #3/0 AWG
wire where the wire length is up to 100 feet (31 m). The
disconnect fuses should be 200 ampere slo-blow. The
transmitter has a 200 ampere primary power disconnect
breaker.
The plate transformer and its associated rectifier are housed
in a separate enclosure that can be located up to 20 feet from
the transmitter. Nine wires are used fro interconnection, six
ofthese wires supply the plate transformer primary, two
wires return the high voltage dc from the rectifiers to the
transmitter. The remaining wire is a safety ground that
connects between the transformer chassis and the transmitter
chassis. The six primary wires and the safety ground \vire
are to be enclosed in the same two inch conduit. The two dc
high voltage wires are to be enclosed in a separate conduit.
Holes are provided in the tops ofthe transmitter and
transformer enclosures for attaching the conduits.
AC line transient suppressors are suggested for the primary
I lines. For recommendation ofsuppressors, call CE Field
Service.
2-1.2 RF Output Power.
The RF output power termination is a 3-1/8" EIA flange
located at the top ofthe directional coupler just above the
PA cavity.
2-1.3 Transmitter Cooling.
In many locations ventilating a building is preferred over air
conditioning. Air conditioning equipment is mechanical and
can break down, is initially expensive, and is expensive to
maintain and operate. The 816R-5C transmitter can operate
in a room environment where temperatures can be as low as
-4 degrees F to as high as 122 degrees F. There are several
different ways to ventilate a room that \vill be discussed in
following paragraphs. Refer to Figure 2-2 for nominal heat
balance values.
2-1.3.1 Exhaust Fans. There are times when exhaust fans
are the best means ofventilating a transmitter space. Ifthe
room is large and it is not possible to locate the transmitter
near an outside wall, exhaust fans may be the only
reasonable way to ventilate a room. It is better in this
situation to vent the transmitter directly to the room or
through a short duct to the attic and use exhaust fans in the
room or the attic. It is important to arrange the transmitter
exhaust so that there is no chance ofrecirculation ofexhaust
air back into the transmitter.
There are many good ways to make an installation utilizing
exhaust fans and one method will be described here. Ifthe
room has a high ceiling (more than 10 feet), install a drop
ceiling about eight feet from the floor. Vent the transmitter
exhaust directly into the space above the drop ceiling. Let
the transmitter take air from the room. At the four comers of
the drop ceiling install air registers that will allow air from
the room to escape into the area above the drop ceiling.
Install an exhaust fan that will evacuate the area above the
drop ceiling. This method will not have the exhaust fan
competing with the transmitter fan and blower, will prevent
recirculation (providing exhaust fan does not fail), and will
provide ventilation for the transmitter space. There are
variations ofthis scheme that will allow recirculation
(controlled by a thermostat) in the winter to heat the
transmitter space. Although exhaust fans and blowers are the
most common method ofventilating transmitter spaces they
are not the best in some cases. The three cautions listed
below are some reasons for choosing another method when
there is a choice.
1. An exhaust fan allows unfiltered air into the transmitter
by expelling air from the room or building and pulling
air into the room through any and all openings in the
room. The transmitter space should be as clean and dust
free as possible. It is not likely that the transmitter space
can be air tight except for the filtered air intake. The
unfiltered openings will allow dust and dirt into the
transmitter space.
2. An exhaust fan results in dead air spaces since it does
not "stir" the air in a room which makes "dead air
spaces" possible. There is usually only one intended air
inlet to a transmitter space and the air movement is from
that inlet directly to the exhaust fan.
Change 3
2-1

INSTALLATION
2-1.3.1 Exhaust Fans. - Continued
3. In installations where the transmitter is ducted to the
outside and takes air from the room, the exhaust fan is
competing with the transmitter cabinet fan and cavity
blower for air through the same room air inlet. In this
situation, the greater capacity ofthe exhaust fan will
reduce the transmitter cooling ifthe room air inlet is not
large in size. Where exhaust fans or blowers are used,
the room air intake must be large enough so that the
room in not under negative pressure. Negative pressure
at the transmitter air inlet has the same detrimental effect
as back pressure ofthe same amount at the transmitter
air exhaust.
2-1.3.2 Positive Pressure. Positive pressure ventilation
forces air into the room and the air escapes through
openings in the room. The air may be forced into the room
with propeller type fans or with centrifugal blowers.
Propeller type fans move more air with smaller motors than
will centrifugal blowers. A 30 or 36 inch fan is quiet and
can move more than 3000 cfin ofair into a room and use
only a 1/4HP motor. Some ofthe advantages ofpositive
pressure ventilation are:
1. All the air entering the room comes through one opening
which can be easily filtered. When doors or windows are
opened, air moves out through the opening.
2. A fan blowing air into a room will "stir" the room air
reducing the risk ofdead air space. Deflectors at the fan
can be used to direct air into areas that might not
otherwise have moving air.
3. All fans aid each other. The fan that is forcing air into a
room is aiding the transmitter fans in cooling the
transmitter. All the fans, the room fan, the transmitter
cabinet fan, and the power amplifier cavity blower are
moving the air in the same direction through the
transmitter.
4. Like the exhaust system, the pressure system will also
ventilate the room. The transmitter will exhaust about
500 cu-ft/min. ofair to the outside. Ifthe room fan is
capable ofmoving three or four thousand cu-ft/min. of
air into the room, another opening in the room must be
provided for room ventilation.
An example ofpositive room ventilation will be described
here. This is intended only as an example and can be
modified to meet your particular requirements.
816R-5C
as possible. Position the transmitter so that the exhaust duct
\vill not interfere with the coaxial RF output line. Ifthe total
duct run is eight feet or less and there are no more than two
elbows, 16 inch round or the equivalent square duct can be
connected directly over the transmitter exhaust output using
sheet metal screws. (Use care when drilling holes for sheet
metal screws so as to avoid metal shavings falling into the
transmitter.) The duct will have to be turned down at the
outside to prevent rain and snow from getting into it. A bell
type transition should be used at the end ofthe duct to
reduce turbulence.
The duct above the transmitter will have two dampers and
an opening to the room. The dampers will be motor
controlled and mechanically linked together so that the
opening to the room will be closed offat the same time that
the air from the transmitter will be directed to the outside.
With the dampers in the second position, the air from the
transmitter will be directed to the room instead ofoutside.
The mechanical linkage is necessary to prevent the
possibility ofboth dampers being closed at the same time.
This arrangement will allow the transmitter to exhaust to the
outside in the summer and recirculate to the inside in the
winter.
A fan that has enough capacity to change the room air at
least once each minute is installed in the wall. This fan pulls
filtered air into the room through motor controlled louvers.
A 3000 cfm fan will change the air once a minute in a
15X20 foot room having a 10 foot ceiling.
An opening with motor controlled louvers is provided in the
same wall where the fan is mounted. The reason for intake
fan and room air outlet being on the same wall is to
minimize the effects ofwind on the ventilation system. If
both inlet and outlet are on the same wall, the effects of
wind, regardless ofdirection, is neutralized since the wind
pressure is the same on both. The transmitter air exhaust
should be on this wall also. The transmitter exhaust should
not be positioned so that there is a risk ofrecirculation.
With motor control on inlet and outlet louvers and
transmitter duct dampers, it is possible to control the
operation oflouvers, dampers, and the ventilation fan with
thermostats. Set the thermostats, based on environmental
conditions, to maintain the required equipment operating
temperature at all times. Three conditions are described
below that will give different results:
Locate the left end or the rear ofthe transmitter near an
outside wall in order to keep the exhaust ductwork as short

2-1.3.2 Positive Pressure. - Continued
1. A condition of maximum ventilation and couling will
result during the hottest periods. The transmitter will be
ducted to the outside and the intake fan will be running.
The outlet wall louvers will also be opened to permit
room ventilation.
2. A condition of minimum ventilation will exist at times
when it is not necessary to run the room intake fan, but
the transmitter should be vented to the oUf-,ide. Under
these conditions the transmitter exhaust dampers will
direct the transmitter exhaust to the outside, the outlet
wall louvers will be closed, the fan will be off, and the
inlet fan louvers will be open to allow fresh filtered air
into the room and transmitter.
3. A condition of recirculation for heating will exist during
cold periods. The transmitter exhaust dampers will be
positioned to allow transmitter exhaust air into the room
and all outside outlets and inlets will be closed.
The system described will require two heating type
thermostats and control relays. One will be set to
approximately 65 of and the second will be set to
approximately 85 of.
At temperatures above 85 of, the first condition described
above will exist.
For temperatures between 65 OF and 85 OF the second
condition described above will exist.
For temperatures below 65 of the third condition described
above will exist.
The thermostats should be mounted approximately seven
feet off the floor and in an area of the room where the
temperature is not influenced by heat radiated by the
transmitter or by direct air flow from the room intake fan.
The transmitter space should also be provided with a
thermostatically controlled heater that can be set to
approximately 50 of. This will provide heat during
maintenance periods or during times that the transmitter is
off-the-air, if not a 24 hour operation.
2-1.3.3 Transmitter Exhaust Duct. Regardless which air
system is used, careful consideration must be given to
location of transmitter, air intake, and air outlet vent when
using outside air for cooling room and equipment. First,
consider where to place the transmitter. The transmitter
exhaust will be vented to the outside and transmitter will
take air from the room. Since the transmitter will exhaust to
816R-5C
the outside, the exhaust vent on the transmitter should be
placed as close as possible to an outside wall. Although it is
highly undesirable, it is possible to exhaust through the roof
but extreme care must be used to weatherproof and leak
proof the ductwork above the transmitter. Since water that
may leak at the ductwork will likely get into the transmitter,
it is absolutely necessary to check for leak proofing often. In
any case the ducts must be kept as short as possible to
minimize back pressure at the transmitter outlet. Remember
that elbows, vent caps, and hoods all add extra resistance to
air flow through the transmitter. In most installations, the
transmitter can be placed so that no more than eight feet of
exhaust duct is needed. If this is possible, 16 inch round
duct or the equivalent rectangular duct will be acceptable.
Do not use more than two elbows. It is not a good practice
to connect more than one transmitter to the same exhaust
duct. Let each transmitter have its own individual exhaust
duct.
Where possible use large ductwork instead of duct fans.
Duct fans may be required if the duct run is long but duct
fans increase air resistance if they fail ~ therefore, some
method of monitoring and interlocking to the transmitter
must be used if there is no alternative to the use of duct fans.
2-2. UNPACKING AND INSPECTING
2-2.1 Domestic Shipments.
The uncrated transmitter cabinet is shipped on a shipping
skid. The transmitter is attached to the skid by shipping
bands. Inspect for loose screws and fasteners. Ensure all
controls operate freely. Examine the cabinet for dents or
scratches. Ensure cable and wiring connections are tight and
situated clear of obstructions.
If any item is freight damaged, the customer should accept
the equipment, note the damage on the shipping documents
and immediately file a freight claim. All boxes and packing
material should be retained for the freight inspector. Refusal
to accept delivery of damaged equipment removes the
evidence and makes freight damage reimbursement
complicated or impossible.
2-2.2 International Shipments.
The transmitter is shipped in a skid type crate with
unpacking instructions stenciled on the side. Heavy iron
components are crated separately, bolted down to a 2-inch

2-3.3 Connect Primary AC Power. - Continued
Perform the following procedure to connect prime ac power
to the transmitter from the customer supplied disconnect
breaker box:
1. Connect the input power wiring from the customer
supplied fuse or circuit breaker panel with a 200 ampere
rating. Using a #3/0 AWG cable, (follow local
"Electrical Code" to determine wire size for a 200
ampere fused service) connect 3-phase power to
transmitter terminal board A8TB 1. Connect the power
AC GND to the GND terminal adjacent to A8TBI. Do
not turn on power at this time.
2. Install the transmitter right end panel by hanging the
panel on the two post at the top corners of the cabinet
and pushing the panel down on an in at the floor end of
the panel. Tighten the two hex head bolts at the bottom
end of the end panel.
2-3.4 Install Remaining Assemblies.
Install the following assemblies which were removed for
shipment:
1. Install the 802B Exciter by performing the following
steps:
a. If the 802B Exciter was not factory installed, mount
it in the area provided in the transmitter center
section. Connect an rf cable from the exciter output
to the driver input (A3Jl). Attach the MUTE
voltage leads to A4TB 1-9. Connect the 117 Vac
power cable to the exciter. Refer to the 802B Exciter
instruction book for installation of audio input
cables.
b. If the 802B Exciter is to be mounted separately from
the transmitter, make sure the voltage source
matches the voltage on the voltage selector card at
the rear of the exciter. Refer to the 802B Exciter
manual for ac power installation. The exciter mute
voltage must also be connected to the 802B Exciter
TB 1-9. The RF output from J3 of the 802B Exciter
will be connected to the Driver RF input (A3JI)
using RG-223 cable or equivalent.
2. Transformers TI and T2, filter inductors LI and L2, and
filter capacitor C1 may have been removed to facilitate
shipping. Install these components if they were shipped
separately.
3. Install the PA tube using the procedure outlined in
paragraph 5-5.1
2-10
816R-SC
4. If remote control is used, run the external wiring from
the remote unit into the transmitter and connect it as
shown on Figures 2-5 and 2-6.
NOTE
The positive plate current sample, AIOTB2-9
must be connected to the ground side of the
remote metering circuits if one side of the remote
metering is grounded. The negative plate current
sample AI0TB2-8 will then be connected to the
remote metering input. The open circuit voltage
at AI0TB2-8, -9 will be approximately 7.2 Vdc
when plate current is 3.0 amperes. An external
voltage divider may be required to obtain a
sample that is within allowable limits for the
remote control. Refer to Figure 2-7.
CAUTION
ENSURE THAT THE TRANSMISSION LINE
AND ANTENNA PRESENT A 50 OHM
IMPEDANCE AND A VSWR NOT GREATER
THAN 2:1 TO THE TRANSMITTER AT THE
OPERATING FREQUENCY. DAMAGE MAY
RESULT FROM AN IMPROPER IMPEDANCE
MATCH BETWEEN THE TRANSMITTER
AND THE RF SWITCH, TEST LOAD, OR
TRANSMISSION LINE.
5. Connect the customer-supplied, 50-ohm transmission
line to the RF output connector mounted on top of the
transmitter cabinet.
CAUTION
FOR 60 HZ OPERATION ONLY, THE
TRANSFORMER PRIMARY TAPS MUST
NOT BE SET MORE THAN TWO TAPS
LOWER THAN THE HIGHEST LINE
VOLTAGE EXPECTED. FOR EXAMPLE, IF
LINE VOLTAGE IS 245 VOLTS, THE
SCREEN TRANSFORMER PRIMARY TAPS
CAN BE SET TO THE 230, 240, OR 250 VOLT
TAPS. IF LINE VOLTAGE IS 240 VOLTS,
THE SCREEN TRANSFORMER COULD BE
SET TO THE 220 VOLT TAPS IF
NECESSARY TO INCREASE TRANSMITTER
POWER. TRANSFORMER TAPS SHALL NOT
BE SET TO LOWER TAPS THAN THE
HIGHEST EXPECTED LINE VOLTAGE
WHERE 50 HZ PRIMARY POWER SOURCE
IS USED. FAILURE TO COMPLY MAY
RESULT IN DAMAGE TO EQUIPMENT.

6. The transmitter is shipped with all transformers on the
highest voltage taps unless specific instructions are
given regarding source line voltage. This is done to
prevent damage where line voltage may be higher than
transformers are tapped for and power is applied
without changing taps.
The broad range of allowable voltage sources (200 to
250 volts) is made possible by the availability of
different primary tap connections of power transformers
A14Tl, T2, T3, and AIOT1. Figures 2-8 and 2-9, and
816R-SC
Table 2-1 show the details of the proper primary line
connections for various source line voltages. Figures
2-10 shows the proper T2 secondary line connections
for various input line voltages.
In addition to the primary taps, the screen transformer
(T2) has three sets of secondary taps. These secondary
taps are identified as 100 %, 85 0/0, and 70 0/0. The dc
screen voltage will be 800 volts when the primary taps
match the source line voltage and the secondary leads
are connected to the 100 % taps. For example if the
secondary leads are moved to the 70 % taps the dc
screen voltage will be lowered to 560 volts.

OPERATION
SECTION 3 - OPERATION
3-1. GENERAL
The transmitter may be operated from the local control
panel or by remote control. Once the transmitter has been
installed and properly tuned, it is only necessary to monitor
meter indications and to make periodic minor tuning and
loading adjustments. Instructions for the 802B Exciter are
found in the Exciter Instruction Manual.
3-2. CONTROLS AND INDICATORS
Refer to the following figures and tables for a general
description ofthe operating controls found on the front
panels ofthe transmitter. Figure 3-1 shows the location of
the control and indicator panels. Figures 3-2 through 3-5
show details ofeach panel. Tables 3-1 through 3-4
supplement Figures 3-2 through 3-5.
The PA grid tuning control is part ofPower Amplifier
Cavity A12. The control shaft extends through a hole in a
structural panel. The control knob is shown in Figure 3-1.
This control allows adjustment ofPA grid circuit resonance.
3-3. INITIAL TURN-ON PROCEDURE
WARNING
DISCONNECT PRIMARY POWER BEFORE
SERVICING THIS TRANSMITTER. SHORT
ALL CAPACITORS AND POWER SUPPLIES
WITH GROUNDING STICK. VOLTAGES IN
THIS TRANSMITTER ARE DEADLY.
1. Ensure transmitter has been assembled and connected
according to instructions in Paragraphs 2-1 through 2-3.
2. Remove access panel ofCard Cage Assembly for
access to the control circuit cards. Check the circuit
cards for proper installation.
3. Install Card Cage access panel and ensure all doors and
panels are properly closed or installed.
4. Ensure all transmitter circuit breakers on A6 panel are
OFF.
5. Connect primary power to transmitter and set AC LINE
circuit breaker to ON.
6. Set the 24 VDC POWER SUPPLY and BLOWERS I
circuit breakers to ON. Check the PHASE LOSS
indicator on the A 1 Control Panel (see Figure 3-2). If
this indicator is not on, set AC LINE circuit breaker to
OFF. Remove the right front bay access panel. Locate
A8K5 (the phase loss/phase rotation monitor) and tum
its control to minimum (full counterclockwise). Install
the access panel and restore primary power. Ifthe
PHASE LOSS indicator is still not on, shut offprimary
power and disconnect power from power input lines.
Interchange any two primary input leads at A8TB1
(Figure 6-15). Restore primary power and check
indicator.
7. Adjust the Phase Monitor A8K5 phase loss threshold.
WARNING
HIGH VOLTAGES ARE EXPOSED WHEN
CABINET DOORS OR ACCESS PANELS ARE
OPENED. DEATH ON CONTACT MAY
OCCUR. BE CAREFUL WHEN
PERFORMING THE FOLLOWING
PROCEDURES.
a. Set AC LINE circuit breaker to OFF and remove
the right front bay access panel.
b. Block the interlock grounding switch, on the right
front bay access panel, in the open position.
NOTE
The phase loss/phase rotation monitor will shut
the transmitter off when phase loss or incorrect
sequence is detected. A phase loss will be
detected if the line voltage drops below the
threshold voltage level which is set by turning
the control on K5. The threshold voltage range is
190-270V and it must be set below the lowest
expected line voltage. To accomplish this, the
line voltage should be at the lowest expected
level when performing the following adjustment.

20. Slightly adjust the PA LOADING and PA TUNING
controls until maximum power output is displayed on
the POWER OUTPUT meter.
21. As the transmitter warms up, the IPA reflected po\ver
will rise. Re-tune the PA GRID TUNING as needed to
keep the reflected power below 75 watts (final value is
less than 20 watts). Once the IPA reflected power
appears stabilized, repeat Steps 19 and 20. The final
setting should be established after the transmitter has
been on for at least 30 minutes. Do not re-tune the grid
after the fmal setting has been established.
NOTE
Operating parameters will become stable
within 15-20 minutes. All fine tuning and
recording of operating parameters should be
performed only after the transmitter has
stabilized.
22. RAISE or LOWER the POWER ADJUST control until
- the POWER OUTPUT meter displays the station's
authorized power level. Ifspecified by the customer,
the meter was calibrated at the factory to indicate 100%
at this power.
23. Compare meter readings with those listed in the factory
test data located at the back ofthis manual. If
additional tuning or transformer tap adjustment is
required, refer to the adjustment procedures listed in
Paragraph 5-7.
24. Set POWER CONTROL switch to AUTOMATIC.
Adjust the power monitor/control card A2A6R8,
located in the card cage, for 100% output power if
necessary.
25. PA TUNING AND LOADING (For best efficiency).
There is not likely to be a plate current dip within the
normal range oftuning control. There are, however,
three indicators to be observed for proper PA TUNE.
Power output and screen current will be maximum. PA
plate current will change as the tuning is changed. Plate
current will increase when the tuning control is held in
the raise position. When the shorting plane is
positioned correctly, the PA screen current and power
output will go through a peak. Refer to Figure 3-6 for
an indication ofwhat to expect as the tuning control is
run through its total mechanical range, from one limit
to the other. Notice that power output is the same at
point A and point B, but that plate current is greater at
point B. The proper tuning point is at point A which
results in maximum output and also the least amount of
plate current (not plate current dip). The loading
control is adjusted for maximum RF output. PA screen
current decreases when loading is raised and increases
Change 1
when loading is lowered. Normally, screen current is
between 300 - 600 mAo The screen current is
dependent upon loading, power output requirements,
plate and screen voltage, and individual tube
characteristics. When the PA tube is replaced, screen
voltage may have to be changed in order to obtain the
desired power output.
26. MAXIMUM POWER OUTPUT ADJUSTMENT.
NOTE
This procedure is intended to maintain
authorized station maximum po,ver output with
line voltage variations.
a. Press the RAISE switch ofthe POWER ADJUST
control until maximum power output is displayed
on the POWER OUTPUT METER.
b. Ifthe maximum power output is not more than 50/0
above the authorized station maximum output,
skip to Step h. Ifthe maximum power output is
more than 5% above the authorized station
maximum output, proceed to Step c.
c. Press the PLATE OFF and FILAMENT OFF
switches on control panel AI.
d. Tum offprimary power to the transmitter.
e. Refer to Figure 2-5 and Table 2-1, and change
wires to the screen transformer terminals to
decrease screen voltage.
f. Reapply primary power and press the FILAMENT
ON and PLATE ON switches on control panel AI.
g. Repeat Steps c through funtil the maximum
transmitter output is approximately 5% above the
authorized station maximum output.
h. Compare the PLATE VOLTAGE reading with the
plate voltage listed in Tables 3-5 and 3-6 for the
authorized station maximum power output.
(Linear interpolation oftabulated values may be
necessary.) Ifthe compared voltages differ by
more than 10%, proceed to Step i. Ifthe compared

816R-5C
THEORY OF OPERATION
SECTION 4 - THEORY OF OPERATION
4-1. GENERAL
The FM Transmitter, 816R-5C, operates in the 88 to 108
IMHz range at a maximum rated RF output of35 kW. A CE
802B solid state, wideband, FM Exciter provides excitation.
The transmitter is equipped with circuits that maintain
constant power output and protect the transmitter from
overload conditions. A control panel provides complete
transmitter metering and tuning controls. Refer to the
overall schematic diagrams for detailed circuit information.
4-2. FUNCTIONAL DESCRIPTION
Refer to Figure 4-1, an input signal (monaural, stereo
composite, or SCA) is supplied to the exciter. The exciter's
RF output drives a two stage power amplifier. The first
stage, the intermediate power amplifier (IPA), raises the
output to a level of 500 Watts. The last stage, the RF power
amplifier, raises the output to the transmitter's rated power
output. The power amplifier is followed by a low pass filter
and a directional coupler which is connected to the station's
antenna system. A dc sample ofthe forward power from the
directional coupler (DC 1) is monitored by the auto power
control circuit. Ifa change in output power is detected, a
signal is sent to the power control board that increases or
decreases the plate and screen power supply input voltage to
compensate. A sample ofthe reflected power is also
monitored by the power control circuits. If an excessive
amount ofreflected power is detected, the control circuits
I remove the transmitter plate voltage. The 24 Vdc power
supply provides power for the control circuits.
4-3. RF CIRCUITS
Refer to Figure 4-2 for a simplified diagram ofthe RF drive
path. The drive path consists ofthe exciter A4, intermediate
power amplifier (IPA) A3 with its directional coupler
A3DCl, coupling capacitor AI2Cl, and power amplifier
(PA) VI with its grid tuning components AI2C3, AI2Ll­
L3, and A 12C2. IPA metering and 3-phase power supply
control circuits are also shown in Figures 4-2 and 4-4.
4-3.1 Exciter, A4.
and Amplifier Assembly as described in the following
paragraphs. Refer to Figure 4-3 and Schematic 195125.
4-3.2.1 IPA Metering, AI.
The IPA metering panel permits measurement of IPA
supply voltage, current, forward RF power, and reflected
RF power. The metering panel printed circuit board
contains all meter calibration pots, a voltage regulator (U1),
an op amp/comparator (U2), and the metered parameter
select switch (S 1). The operational amplifier amplifies the
reflected power signal (V2-5) from the IPA directional
coupler. This signal is compared to a reference voltage
using the comparator ofU2. When the reflected power
signal (U2-3) exceeds the reference voltage (U2-2), V2-1
goes high, causing the VSWR LED to light. The metering
circuitry is powered from the 50 Vdc IPA supply through
Rl and VI on the card. Device VI is a 12 Vdc regulator.
4-3.2.2 Status Assembly, A2. The Status Assembly has
two LEDs which indicate power ON and high VSWR.
Signals for illuminating the LEDs are developed on the
A3A1 IPA Metering Assembly.
4-3.2.3 Amplifier Assembly, A3. The Amplifier Assembly
consist ofan RF splitter, two RF amplifiers, an RF
combiner, and a 50 Vdc power supply. The splitter consists
oftwo quarter wave lengths 75 ohm line and a 100 ohm
balancing resistor. The input to thesplitter, from the
exciter, is equally divided and impedance transformed to the
input of each ofthe two RF amplifiers. Each amplifier has
a power gain ofapproximately 16 dB and the outputs of
both amplifiers are summed together by the combiner to
provide an output of 500-600 watts. The combiner is the
reverse ofthe splitter and consists ofthe same parts, only
with greater power handling capability. The IPA is
followed by directional coupler A3DC 1. The coupler drives
the IPA RF power meter and a VSWR warning indicator.
The IPA receives its dc power from a 50 Vdc supply, part of
which is on the A5 assembly. The Amplifier Modules,
A3Al and A3A2, consist oftwo circuit card assemblies
mounted on a common heat sink, refer to Schematic
189397. The two circuit card assemblies are RF Amplifier
and Control Assembly.

THEORY OF OPERATION
816R-5C
4-3.2.3.1 RF Amplifier. The RF Amplifiers use a system
of lumped coaxial lines to match the drain-to-drain
impedance of 12.5 Ohn1s, balanced, to 50 Ohms, balanced.
See Schematic 189214. Transmission lines TL1Oland
TL102, which have a characteristic impedance of 25 Ohms,
are seriesed at their output connection to TL103 (for 50
Ohms) and are paralleled at their input connection to the
amplifier transistor, Ql, to present a 12.5 Ohm impedance.
The balanced 50 Ohm output impedance at the junction of
TL101 and 102 must be converted to a unbalanced output
signal for coaxial transmission. This is accomplished by
TL103. The length ofthis line is just long enough to
present a large impedance to the unbalance current in its
shield. This type ofcurrent balun results is excellent
balance to the transistor drains.
The amplifier module is untuned. The operation ofthe
transformers and the balun serve to limit the operating range
to 80-120 MHz. The input ofthe amplifier is similarly
broadband. Capacitor C 101 is adjusted to insure that
variations iI} such things as the gate capacity ofthe
amplifier FET transistor and the leakage reactance ofthe
input transformer are balanced out to provide a good input
match to drive the Splitter over the operating range.
The output transistors ofthe PA Modules operate in
saturated push-pull, Class BC, with an operating angle of
approximately 150 degrees and a drive level, at full output,
ofup to 20 Watts. This results in a conversion efficiency in
excess of 750/0. The bias adjustment for the RF transistor,
R220, is adjusted to give an operating bias of+ 1.5 to 3.5
Vdc. This bias adjustment also serves as a gain control.
During final testing, slight adjustment ofthe bias control is
made to insure that the gain ofboth RF amplifiers are equaL
There is an optimum drive level for the PA Modules. As
the amplifiers are under-driven, they go into a linear mode
and conversion efficiency drops. Over driving the
amplifiers results in excessive harmonic content at the
amplifier drains which also causes a drop in conversion
efficiency. Drive level is adjusted by varying the exciter
output to obtain the desired drive power to the final
amplifier tube.
4-3.2.3.2 Control Assembly. The Amplifier Module
Control Assembly is an on-board protection system to
protect the module from over-current and over-temperature.
The Schematic Diagram, 189211, shows that the operating
volt..ge for the protection circuitry, + 15 Vdc, can be derived
from either the +24 Vdc Control Power Supply ofthe
transmitter or from the +50 Vdc supply through the
isolation diodes, CR201 and CR202. Voltage for the RF
transistor flows through the over-current shunt, R209, and
the ON/OFF switch, Q203. Switching transistor Q203 is
4-2
either ON or OFF in this circuit. The voltage on either side
of the over-current shunt, R209, is reduced to +8 Vdc by the
bridge circuit. As the current flow, the over-current shunt
causes a voltage drop, 0.5 Vdc when the current is 10
amperes. The voltage differential is amplified by a buffer
amplifier so that the output ofbuffer, U201A is 6.4 Vdc,
when the current through the amplifier is 10 amperes. This
voltage appears on 11-2 and is used to monitor the current in
each module. This current-related voltage is also buffered
and divided and feeds the non-inverting input ofU201B. A
preset reference voltage of+4 Vdc is applied to the
inverting input ofU20 lB. When the current through the
amplifier exceeds 12.5 amperes, the output ofU201 goes
high and fires the SCR, Q202. This, in turn, pulls the base
ofthe switch driver, Q201 low. This turns Q201 ON which
causes the gate voltage of Q203 to rise to input voltage
value. Unless the gate ofQ201 is low, the switch turns OFF
and removes voltage from the amplifier. Each RF Module is
also protected with a 12 ampere fast-acting fuse.
Over-temperature operation is detected by the thermal
switch, S 1, on the amplifier assembly. This switch is
mounted in contact with heat sink close to the attachment
point ofthe amplifier transistor. Closure ofthe switch due
to over-temperature (80 degrees C.) causes current to flow
in the opto-isolator U202. This causes the voltage across the
opto-isolator output transistor to fall to zero. Again, the
switch, Q203 opens and removes voltage from the
amplifier. Operation ofthe thermal switch is through
resistor R223.
4-3.3 RF Power Amplifier, A12.
The RF power amplifier is driven by the IPA through a
matching network consisting ofthe COUPLING control
(CI), the PA GRID TUNE control (C2), and Ll, 2, 3 (See
Figure 4-2). Capacitor C3 and resistor Rl swamps the
power amplifier grid circuit and provide a more uniform
impedance to the IPA under varying drive conditions.
Inductor L 14 and the distributed capacity ofresistor R75
couple R75 to the cavity, forming a suppressor that
dampens the higher order cavity resonances that can occur
near the third harmonic ofthe output frequency. Cathode
tuning (or peaking) capacitor C39 improves the bypass
action at the operating frequency. Inductor L5 is the power
amplifier grid bias feed choke.
The power amplifier is a plate tuned 4CX15 ,OOGA tube that
is operated as Class C. The tube screen is grounded and the
cathode is placed 750 Volts (nominal) below ground to
provide screen voltage, as shown in Figure 4-5. A fixed bias
from the power amplifier bias power supply is applied to the
control grid through terminal A5E12, resistor A5R13, and
terminal A5E13. When an input signal is present, grid
Change 2

816R-5C
THEORY OF OPERATION
current flows and develops grid leak bias across resistors
R35 and R36. The increased negative potential on the grid
causes the diode in the power amplifier bias supply to
reverse bias, preventing grid current flow through the
supply. Hall effect probe A5Z1 monitors the amount of grid
current for control panel metering.
The power amplifier plate circuit is coarse-tuned from 88 to
108 MHz by resonating adjustable coaxial resonators,
Figure 4-6. The resonators are in the area between the tube
shelf and the sliding shorting plane. Two motor-driven
capacitors permit more precise tuning (capacitor C51) and
loading (capacitor C50). RAISE or LOWER switches S10
or Sll (PA TUNING) and SI2 or S13 (PA LOADING) on
control panel A 1AI, control the capacitor drive motors. The
dc blocking capacitor C2 is located between the top of
power amplifier tube and input to the air chimney. Figure
4-7 shows the electrical equivalence ofthe plate tuning
circuit.
4-3.4 Low-Pass Filter, A7.
Low Pass filter A7 (Figures 6-1, sheet 2) consists oftwo
coaxial filters in tandem. The first filter has a cutoff
frequency of 130 MHz, while the second has a cutoff
frequency of 300 MHz.
4-3.5 Directional Coupler, DCI.
The directional coupler provides a proportional dc voltage
to both the forward and reflected circuits ofA2A6. The
output ofeach is then routed to, and can be displayed on,
the Forward! Reflected Meter (AIM4).
4-4. POWER SUPPLIES AND POWER CONTROL
CIRCUITS
4-4.1 General.
Refer to transmitter schematic 189632 for the following
discussion. There are five separate power supplies in the
transmitter. Three ofthe five, the plate, screen and power
amplifier bias power supplies provide voltages to the power
amplifier. The Driver supply, furnishes voltage to the IPA
Istage. The 24 Vdc power supply provides power to the
controI circuits 0
4-4.2 24 Vdc Power Supply, PIO A10. I
The 24 Vdc supply is a fully self-contained power supply.
A parts list and schematic diagram is included in this
manual.
4-4.3 Power Amplifier Bias Power Supply, PIO Al O.
The power amplifier bias power supply provides the power
amplifier with fixed grid bias that holds the tube near cutoff
when no signal is present on the grid. Single-phase primary
power is applied through contactor A8K} and step-up
transformer T} to a bridge rectifier network. An L-section
filter is formed by inductor L 1 and capacitor C2.
The power supply output is applied to the grid ofthe power
amplifier through diode CR5. Diode CR5 blocks grid
current flow through the supply when the grid leak bias
exceeds the fixed bias. A sample ofthe bias voltage is
applied through resistor R3 to front panel meter AIMI for
monitoring.
4-4.4 PA Plate Power Supply.
The power amplifier plate power supply provides plate
voltage to the power amplifier. Primary components ofthe
supply are transformer AI4TI, 3-phase bridge rectifier
assembly A14ZIA, ZIB, ZIC, filter choke Ll, and filter
capacitor C1. A meter multiplier board, A12A1, samples
plate voltage and allows constant monitoring. Input power
to transformer A14TI is controlled by SCR
(silicon-controlled rectifier) power control unit A9. This
unit, connected as a closed loop regulator, maintains
constant power output to offset conditions ofvarying line
voltage.
4-4.5 Power Control Unit, A9.
Power control unit A9 regulates the 3-phase ac power input
to the power amplifier plate and the power amplifier screen
transformer. SCR assembly Z 1 has three SCR pairs; one
pair in series with each primary winding ofthe 3-phase
power transformers. Each pair is connected within the delta
circuit ofthe transformer primaries. Three control cards are
located within the A2 card cage. Each control card controls
the firing (tum-on) point of one SCR pair (Refer to Figures
4-4 and 4-8).
I
A common dc control signal from power control regulator
A2A6 is fed simultaneously to each control card. This
control signal governs the firing ofthe SCR pairs that
regulate the input power applied to the power supplies.
Upon receipt ofa PLATE OFF control signal, a ground is
placed across the inputs ofeach card.

THEORY OF OPERATION
4-4.6 Power Control Regulator, PIO A2A6.
The po\ver control regulator located on A2A6 provides the
necessary control signals to operate power SCR control unit
A9. Assembly A2A6 supplies a soft-start power amplifier
plate supply tum-on signal, a negative voltage for manual
power control, and amplifier mixer functions for automatic
power control.
IWhen the PLATE ON switch is pressed, 24 Vdc is supplied
to A2A611-30. The 24 Vdc activates transistor Q1 to turn
on relay A8K6. Relay A8K6 in tum supplies 3-phase ac
control power to A2Tl-3. An RC time delay circuit formed
by resistor R41 and capacitor C12 maintains A8K6 closed
for a short interval after the PLATE OFF switch is pressed.
I Transistors Q2, Q3, and Q4, also energized by the 24 Vdc,
provide the dc turn-on signal to the gate cards. Resistors
R34 and R35, and capacitor C11 modify this signal to
soft-start the high voltage power amplifier plate power
supply. Zener regulator VR4 provides -10 Vdc to
MANUAL power adjust resistor A2A9R1. Transistors Q4
and Q5 amplify the control signal and apply the signal to
the gating cards. Capacitor C5 and resistor R36 phase
compensate the power control servo loop.
4-4.7 PA Screen Power Supply.
The 3-phase regulated voltage from the power control unit
is applied through transformer T2 to a silicon 3-phase
full-wave bridge rectifier assembly A5CR1 in the power
amplifier screen power supply. The output ofA5CRI is
filtered and applied to the cathode circuit ofthe power
amplifier at the secondary center tap offilament transformer
A12Tl.
4-4.8 Driver Power Supply, PIO A5.
The driver power supply is a 3-phase, full-wave, type using
a single section choke input filter. It nominally delivers 45
Vdc at 25 amperes to its load. The supply's primary power
is switched through relay A5Kl which is operated by the
PLATE ON circuitry. The supply is protected through
circuit breaker A6CB3.
4-4.9 Filament Voltage Regulator, A2A4.
When the Filament Regulator Card is in the automatic
mode, the filament voltage regulator detects and
compensates for sustained fluctuations in the input ac
voltage (Refer to Schematic Diagram Figure 7-2). The
fluctuations are detected by a true rms detection circuit
which in conjunction with associated circuitry, including
motor control circuits, adjusts the setting ofvariable
transformer A8A2T1. The output voltage ofthe variable
transformer is then applied to the primary ofpower
Change 3
amplifier filament transformer A 12T1. The variable
transformer voltage is also applied to the primary of
detector circuit transformer A2T4.
Voltage for the power supply circuits on the filament
regulator board is derived from sampling transformer A2T4.
This ac voltage is rectified and applied to voltage dropping
resistor R33. Capacitor C24 provides filtering. A
three-terminal 15 Vdc regulator U9 supplies voltage to the
15 Vdc circuits with additional stabilization provided by
capacitors C27 and C28. Voltage dropping resistor R34
feeds three-terminal 5 Vdc regulator U 10 while capacitors
C29 and C30 provide additional voltage stabilization. LED
DS5 indicates voltage present on the 5 Vdc line which
implies that the 15 Vdc circuits are also powered.
Negative supply voltage is provided via diodes CRI and
CR2 via resistor R3 and capacitor C24 to card edge
connection 38 for distribution to other circuit cards in the
transmitter.
A sample ofthe voltage feeding the power amplifier tube
filament transformer is applied via transformer A2T4. This
ac signal is applied to RF filtering components inductor L 1
and capacitor C14. Inductor L I has a 4.7 J1-h parallel
resonance which falls in the FM broadcast band providing a
high impedance path for frequency modulated RF signals.
Capacitor C14 is a 100 pfcapacitor whose series resonance
falls in the FM broadcast band providing a low impedance
shunt path for frequency modulated RF signals. These
filtering components are used in several locations in the
filament regulator card, and provide the same filtering
functions as described here.
The filament voltage sample signal is then applied to the
RMS-to-dc converter circuit via voltage divider resistors RI
and R2, and through capacitor CI5. This RMS-to-dc
converter circuit is based around U7, a true rms-to-dc
converter integrated circuit. The converter directly
computes the true RMS ofany complex input waveform
containing ac components. It has crest factor compensation
which allows very accurate measurements up to 300 kHz.
The crest factor ofa waveform is the ratio ofthe peak signal
swing to the RMS value. Components C17, R17, RI8, C18,
RI9, and C20 provide time constant and filtering functions
for the converter.
4-11

THEORY OF OPERATION
816R-5C
Test point 3 (TP3) provides easy access to the dc voltage
representation ofthe filament RMS voltage. During nonna}
operation ofthe filament voltage regulator, resistor R2 is
adjusted so the output ofthe RMS-to-dc converter circuit is
5.00 Vde when the filament voltage has been preset to the
nominal value by the operator. The output voltage is then
fed to window comparator composed ofU8 and related
devices. The voltage references for the window comparator
are provided by U 11, a very high precision 10-Volt
regulator, and voltage divider components R20, R21, R22,
and R23. In nonnal operation, resistor R20 is adjusted to
provide 5.00 Vdc at TP2. The corrected reference voltages
are then applied to their respective comparators. Pin 5 ofU8
has 5.05 Vdc applied, and pin 10 ofU8 has 4.95 Volts
applied. These voltages will be correct ifresistor R20 has
been properly adjusted for 5.00 Vdc on TP2. The 50 mV
voltage drops are provided by voltage divider resistors R21
and R22. This 100 mV total window provides a total ± 10/0
window for the voltage comparator, and hence for the
voltage regulator circuitry.
Ifthe voltage from the RMS-to-dc converter circuit is
within the 4.95 to 5.05 Vdc window, the outputs ofthe
comparators will both be high and the output ofAND gate
U4C will go high illuminating green LED DS4 indicating
proper filament voltage is present. Ifthe voltage from the
RMS-to-dc converter is not within the 4.95 - 5.05 Vdc
window, the circuit will then operate to make the necessary
corrections ifswitch S2 is in the AUTO position.
Assuming that switch S2 is in the AUTO position, ifthe
filament voltage rises above +1% ofthe nominal value
setting, the following actions are taken. The output ofthe
5.05 Vdc comparator will go low at U8-2 causing the output
ofU4 to go low and DS4, the LOCK LED, will extinguish.
Device U8-1I will go high bringing the input ofU 1-13
high. When either ofthe comparators goes low, indicating a
correction is necessary, U2B, U2D, and U2C in
combination act as an OR gate forcing U 1-1 0 high which in
tum triggers timer, U6. When U6 is timing, the output pin 3
goes high illuminating yellow LED DS 1. At the same time,
UI-3 output goes low which takes the input ofU4-I low.
This output is fed through switch SIA to inputs UI-9, Ul­
12 and U2-1 bringing them all low. Hence, while the timer
is in its timing state, the outputs ofU 1C, U 1D, and U2A are
all high, inhibiting the actuation ofrelays Kl, K2, and K3
respectively. Once the timer U6 has timed out, the inputs of
UIC, UID, and U2A fed from switch SIA are brought
high. At this point ifthe filament voltage is still above the
+I% nominal value, both inputs ofUI will be high,
enabling actuation ofrelay Kl and the clutch assembly on
the filament voltage adjust variac motor. Simultaneously,
both inputs ofU 1D will go high forcing its output pin 11 to
go low. The LOWER LED (DS2) will be illuminated and
relay K2 will be activated which in tum actuates the lower
winding in the motor driving the filament voltage control
variac. Once the variac brings the filament voltage back
inside the range ofnominal operation, the comparator
4-12
output ofU8-2 will go high, and the above logic actions are
reversed removing power from the filament voltage
regulator variac motor.
The raise function operates just as the lower function
described above, but instead activates the raise circuits. It
may be noted that if future adjustments by the operator are
required in the automatic mode, resistor R2 may be used as
a simple filament voltage adjustment control.
The timing period oftimer U6 is provided to guard against
constantly correcting momentary excursions in the filament
voltage. This delay timing period is adjustable from 0 to 12
seconds with resistor R7.
If automatic operation ofthe filament voltage regulator
circuit is not desired, switch S1 can be put in the MAN
(manual) position. This effectively takes the regulator out of
the circuit, but the green LED lock indicator will still show
ifthe filament voltage is within nominal range.
While in the manual mode, momentary switches S2 and 83
can be used to manually activate the clutch and raise or
lower circuits respectively. Other than the timer not being
active in this mode, these switches simulate the output of
the comparators per the operator's command, thus manually
raising or lowering the filament voltage. This provides a
convenient way to determine ifmost ofthe digital logic and
the solid state relay are functioning properly should a
problem occur. Devices U3A and U3B are provided to
insure that the raise and lower functions are not activated
simultaneously by circuit failure or accidentally by the
operator using the manual control.
While in the manual mode, the operator may depress both
the raise and lower switches simultaneously and the only
action to take place is the timing ofU6 as noticed by the
illumination ofyellow LED DS 1. This allows the operator a
convenient way to set the time delay ofU6 without
affecting the other circuits.
Solid state relays K I, K2 and K3 provide a return for the ac
voltages already on the windings ofthe clutch, and the
lower and raise circuits ofthe variac drive motor. Relays K2
and K3 also have the return path for the ac voltages routed
through micro-switches SI and S2 on the variac assembly.
This provides a secondary measure against operating the
filament voltage regulator outside ofthe prescribed range
provided by the mechanical stops on the variac drive motor.

4-4.10 Filament Voltage Distribution.
The filament voltage distribution is shown in Figure 4-9.
Filament voltage regulator A2A4 maintains a constant rms
voltage on the filaments as discussed in Paragraph 4-4.9.
4-5. PRIMARY POWER DISTRIBUTION CONTROL
AND OVERLOAD CIRCUITS
4-5.1 Primary Power Distribution.
The 60 Hz, 3-phase primary power is distributed to the
various circuits ofthe transmitter via circuit breakers and
fuses mounted on circuit breaker panel A6. Refer to Figure
4-10. Circuit breaker A6CB5 is connected inside the delta
ofplate transformer A14T1. It also serves to interrupt
primary power to the PA screen transformer T2 through
associated circuit breaker A6CB4. Circuit breaker A6CB3
controls power to driver power supply (IPA) transformer
T3. AC line voltage metering is provided by ac meter
A2Ml. In addition to the three phase-to-phase voltages,
A2MI can monitor the power amplifier filament voltage.
BLOWERS circuit breaker A6CB2 controls application of
primary power to cavity blower Bland FAN fuses A6F7,
F9, and F12 through filament-on relay A8K2. Relay A8K2
is energized when the filament switch (S2) is turned on.
Application ofprimary power to the filament circuits, the
exciter, the power amplifier bias power supply, and the
power amplifier tuning and loading motors is relay
controlled. Filament-on relay A8KI and blower-on relay
A8K2 control application ofpower to the regulated filament
circuit through auto-transformer A8A2TI. Relay A8Kl also
controls application ofpower to 802B Exciter A4, to power
amplifier bias power supply, PIO A10, and to the power
amplifier tuning and loading motors B2 and B3
respectively. Power to the exciter and the motors is through
isolation transformer T4. Time totalizing meter A2M2 is
placed across the load side offilament-on relay A8KI.
The filament, exciter, and power amplifier bias supply input
power circuits are protected by associated fuses. These
circuits receive power from the blowers circuit breaker,
A6CB2.
4-5.2 Transmitter Tum-On.
The transmitter is energized by pressing FILAMENT ON
switch AlA1S4 on the A 1 control panel. Relay A8K2 is
energized and is applied to the blower motors. After
sufficient air pressure is created in the power amplifier
cabinet, air switch AI2S1 is closed and relay A8K1 is
energiz~d.
After a 30-second delay, relay A8K4 is energized. The
PLATE ON switch is pressed energizing relay A8K3 which
applies 24 Vdc to the base oftransistor A2A6Q3. This turns I
on the control amplifier, which applies input voltage to the
plate and power supplies.
The transmitter may also be energized by pressing the
PLATE ON switch \vhich latches relay A8K3, and
energizes relay A8K2 through contacts 8 and 5. Pressing
this single switch (PLATE ON) enables the transmitter to
go through the above sequence ofblower, filament, time
delay and plate on.
4-5.3 Exciter Power Control Override.
An output override voltage is supplied to the 802B Exciter
when the plate voltage is turned OFF. This mutes the output
ofthe exciter while the power amplifier plate voltage is
turned OFF (Figure 4-11). The voltage is applied from the
24 Vdc power supply through contacts 3 and 9 ofrelay I
A8K4 to the 802B Exciter power supply regulator.
4-5.4 FWDIREFL Calibrate and Auto Power Control Unit,
A2A6.
4-5.4.1 Functions. The FWD/REFL CALIBRATE AND
AUTO POWER CONTROL portion ofthe A2A6 card
performs these functions (Refer to Schematic 180162):
1. The forward power signal from the directional coupler
is buffered and amplified to provide a panel power
meter reading of 1000/0 at the customer's specified
transmitter power output (TPO). Full scale meter
indication is 1200/0 in the FORWARD POWER
position.
2. The forward power signal from the directional coupler
is compared against either oftwo internal, adjustable
voltages for automatic power control. Two discrete
levels ofpower control are remotely selectable and
maintain the desired power to within 10/0.
3. The reflected power signal from the directional coupler
is buffered and amplified to provide a full scale reading
of 12% ofthe customer's specified TPO on the panel
power meter in the REFLECTED POWER position.
4. The reflected power signal from the directional coupler
is compared against an internal limit to smoothly fold
the forward power level back when a slowly rising
VSWR level is detected. Forward power is reduced to
keep the reflected power at 5 to 60/0 ofthe customer's
specified TPO.

5. A reflected power signal from the directional coupler
can remove power from the transmitter and light the
VSWR tally LED when a rapidly rising reflected power
level greater than I 00/0 ofthe customer's specified TPO
is detected.
4-5.4.2 Theory ofOperation.
The forward power signal from the directional coupler,
DC 1, is amplified and buffered by V4. Resistor R9 is an
offset null adjusted for zero output at TP1 when no input
signal is present. Resistor RIO is adjusted to provide a
100% forward power indication on the panel power meter
(AIM4) at the customer's specified TPO.
The output ofV4 is also present on terminal board
AIOTB2-13, through a 2.2K ohm isolation resistor, R53, to
provide remote metering offorward power.
The positive output ofV4 is coupled through diode CR1l
and compared at the inverting input ofU3 against the
negative voltage from either resistor R8 (Normal Power) or
resistor R7 (Second Power) in the automatic mode. The
output ofU3 is used to raise or lower the transmitter plate
voltage, as necessary, to maintain the selected power level.
The input to V3 is switched from resistor R8 to resistor R7
I by relay K 1 which is activated by applying +24 Vdc to relay
Kl coil through terminal board AI0TB2-1. Normally,
resistor R8 sets the normal operating TPO reference while
resistor R7 is adjusted for some lower value, perhaps
necessary during emergency operation with a generator
unable to supply the full power load.
The reflected power signal from directional coupler DC 1 is
amplified and buffered by VI. Resistor Rl is an offset null
adjustment for zero output at TP2 when no input signal is
present. Resistor R2 is adjusted to cause a 10% reflected
power indication on the panel power meter AIM4 when the
reflected power reaches 10% ofthe customer's specified
TPO. Resistor R3 is adjusted to simulate that 100/0 reflected
power level when the TEST switch S1 is depressed. This
allows testing ofthe VSWR protection and metering
circuits. The output ofVI is fed through resistor R43 to the
gate ofthe VSWR overload SCR A2A5Q4 when the
VSWR protect is in the enable position. Resistor R4 is
adjusted to fire SCR A2A5Q4 when the reflected power
reaches 100/0 ofthe customer's specified TPO. When SCR
Q4 fires, VSWR overload relay A11K9 activates, removing
power from the transmitter and illuminating the VSWR
OVERLOAD LED.
remote metering ofreflected power.
Devices U2 and U3 form the VSWR foldback circuit. A
sample ofthe buffered reflected power signal from U 1 is
fed to U2 through resistor R5. Resistor R6 is the offset null
adjustment for U2 and is adjusted to give zero output at U2­
6 \vhen no input signal is present. The output ofU2 is
coupled through diode CR6 to the automatic power
comparator, U3. Resistor R5 sets the level so that the output
voltage ofU2 will exceed that ofU4, causing the power to
be reduced, when the reflected power exceeds 5-60/0 ofthe
normal TPO. The VSWR foldback circuit is defeated by the
circuitry ofthe ten second timer U5. The timer is triggered
by sampling the anode voltage ofVSWR overload SCR
A2A5Q4. The response time ofthe VSWR foldback circuit
is relatively slow. A sudden significant increase in VSWR,
as in an arc, would cause the VSWR overload SCR to fire.
Power to the transmitter is removed, the VSWR
OVERLOAD LED is illuminated and the VSWR foldback
circuit is disabled for ten seconds. The VSWR foldback
circuit is disabled to allow the VSWR overload circuit to
sample the VSWR at full power thereby preventing
operation into a dangerously deficient load.
4-5.5 Overload Protection.
Relays A5K2, A5K3, and A5K4 are adjusted to energize
and remove power from the transmitter when an overload
occurs in the plate or screen supply or when the VSWR
exceeds a preset level. Screen current through resistor A5R8
produces a voltage that is applied to relay A5K2 through
resistor A5R15. The plate current through resistor A5R7
produces a voltage that is applied to relay A5K3 through
resistor A5R16. When SCR A2A2QS is gated on, a ground
is applied and relay A5K4 is energized. Each relay is
adjusted to trip at a factory preset current level. The relay
contacts are in series with plate control relay A8K3. Ifan
overload occurs, the corresponding relay trips and
de-energizes relay A8K3, removing plate power from the
transmitter.
4-5.6 Overload and Recycle Board, A2A5.
Overload and recycle board A2AS contains circuits that
provide overload indication and memory, automatic power
on recycling, and filament control circuit interlock status
(Refer to Schematic 180167).
The output ofV1 is also present on terminal board
AIOTB2-12 through 2.2K ohm resistor R46 to provide
Change 3
4-17

THEORY OF OPERATION
816R-5C
When an overload occurs in the PA plate, PA screen, or
I VSWR circuits, a 24 Vdc pulse is supplied to the
appropriate SCR Q4, Q7, or Q8. The SCR latches and lights
its associated LED indicator on the A 1 panel to indicate
which overload has occurred. All indicators that have been
lighted by an overload function remain lighted until OVLD
FAULT RESET switch AIAISl6 on the main control panel
is pressed. Plate voltage is removed by overload relays
IA5K2, A5K3, or A5K4. The 24 Vdc pulse that triggers the
SCR is simultaneously routed to the recycle circuit via
diodes CR9, CR11, or CR12 to be used to automatically
restart the transmitter.
The automatic recycle circuit provides a timed restart pulse
for up to four overload occurrences within a 30-second
period. The card as shipped will allow only two restart
pulses in a 30-second period. However, it may be
reconfigured to allow four restart pulses in a 30-second
period by removing the jumper between terminals A and B
on the card and replacing it between A and C.
IThe auto recycle begins when the 24 Vdc pulse is applied to
the base oftransistor Q2 causing it to conduct. The output
of Q2 is fed to timers Uland U4. Timer U 1 provides a
O.5-second delay, then triggers timer U3 which generates a
O.5-second output pulse. This pulse is fed through gate U2A
to inverter Q3 which causes Q6 to conduct and charge
capacitor C22. The charging current of capacitor C22
momentarily energizes relay K 1 which closes the PLATE
ON circuit through switch S2. The charging current of
capacitor C22 also flows through RECYCLE PULSE
indicator LED CR6 giving an indication ofthe recycle
circuit operation.
Gate U2D conducts the output pulse from timer U 1 to
counter U5. Counter U5 counts the number ofrecycle
pulses and provides a logic 1 output at terminal C when four
pulses have been received. Depending on which terminal
has been strapped to terminal A, two or four recycle
attempts in a 30-second period will close gates U2A, U2B,
U2C, and U2D and prevent any further attempts by the card
to restart the transmitter. RECYCLE LOCKOUT indicator
LED CR2 will light to indicate this condition. When the
30-second period oftime has elapsed, a pulse is generated,
inverted by transistor Q 1, and applied to U5 to reset it to
zero. This clears the memory and allows another sequence
to begin. Ifthe maximum count oftwo or four pulses has
not been received in the 30-second period, the timer will
also reset the counter automatically.
AUTO-RECYCLE switch S2 may be used to disable the
auto recycle card when desired. This is usually done during
tune-up or maintenance procedures. RECYCLE TEST
switch S1 may be used to test the automatic recycle circuit
during maintenance procedures by simulating an overload
pulse at the input to the recycle circuit.
4-5.7 Power Failure Recycle Board, A8Al.
In the event ofmomentary loss ofprimary power, the power
failure recycle circuit restores the transmitter to operational
status. Capacitor C3 maintains current flow through time
delay relay A8K4 keeping the time delay circuit active for
short term power outages and a separate circuit provides a
momentary ground at pin 10 when power is restored. The
momentary ground is applied to capacitor A2A5C22 and the
charging current ofthis capacitor pulls relay A2A5K8 in
and initiates the power ON command.
4-5.8 Auto-Manual Power Control Latching Relay and
Transmitter Status Indicators.
The latching relay permits local or remote selection of
manual or automatic power control (Refer to Figure 4-11
and Status and Interlock Simplified Schematic, 189579, in
pouch at rear ofmanual).
The latching relay is connected to the remote control panel
through terminal board A 1OA2. A 24 Vde signal applied by I
manual control switch AIAlS2 or through remote control
interface board will latch relay A1OA2K2 in one oftwo
stable states. AUTO PWR CONTROL switch LED
A1A 1S1 indicates automatic power control is selected and
MAN PWR CONTROL switch LED A1AIS2 indicates
manual power control is selected.
Visual indication ofTRANSMITTER CONTROL
REMOTEILOCAL switches A2A7S 1 or A2A7S2 are given
by status indicator LEDs AIAIDS22 and A1AIDS16.

on the Control Panel A 1. RMT PLT OFF INTLK indicator

place. Panel designations refer to the three bays ofthe
transmitter cabinet (left, center and right) as viewed from
the front ofthe transmitter. REMOTE INTLK indicator
LED A1A1DS20 is lighted when continuity exists between
remote control interface terminal board Al OTB 1-3 and -4.
FAILSAFE INTLK indicator LED A 1A 1DS29 is lighted
when remote relay Al OA2K8 is energized. Indicator LEDs
A1A1DSl1 through A1AIDS21, except for AIA1DS16,
are in series and in sequence as they are connected in the
circuit. Therefore, an interlock must be satisfied before its
status indicator LED will light.
4-5.9 Power Control Relays, PIO A10A2.
Assembly Al OA2 provides remote manual power lower and
raise control. When power is decreased at the remote
control panel, relay K4 is energized (see Figures 4-8 and
4-12). Closed contacts provide 115 Vac to motor A2A9Bl
which adjusts the resistance ofA2A9Rl to decrease the
transmitter power output. When the power is increased at
the remote control panel, relay K6 is energized and closed
contacts provide 115 Vac to motor A2A9B1 which adjusts
the resistance ofA2A9R1 to increase the transmitter power
output.
4-5.10 Remote Relays, PIO A10A2.
Remote relays in Al OA2 parallel the front panel control
operations. Failsafe relay K8 is energized only \vhen 24
Vdc is present in the control circuit. Ifthe 24 Vdc is lost,
the relay de-energizes and removes plate power from the
transmitter. Second power level (low power) relay K7 must
also be energized continuously (24 Vdc) to maintain this
function.

MAINTENANCE
NOTE
The transmitter plate and screen power supplies
will be operating with only one power phase
applied in the following tests. The plate voltage,
screen voltage, and RF po,ver output will be lower
than usual. Exact voltages in these tests are
unimportant.
5. Operate POWER CONTROL ADJUST and observe that
the plate voltage, plate current, and RF power output
change smoothly. Note the maximum plate voltage. If
the power controller phase under test is good, there
should be no breaker trips, no unusual noise from the
power transformers and no building lights blinking.
CAUTION
REMOVE PRIMARY POWER FROM THE
_TRANSMITTER EACH TIME A GATING
CARD IS REMOVED. FAILURE TO COMPLY
MAY RESULT IN CARD DAMAGE.
If none of the cards operate properly in the selected power
controller receptacle, use a different card receptacle and
repeat the test. Perform the same test with each of the
remaining gating cards in the same power controller card
receptacle. The results should be the same for each card if
the card is good. If all the cards operated properly, use one
of the cards to test each of the two remaining receptacles.
This will check the other two power controller phases.
If all cards operate properly in one or two receptacles but
not in another, it can safely be assumed that the cards are
good but either an A2 control transformer or one of the
SCR banks are defective. Experience indicates that the
SCRs are least likely to fail.
5-7. ADJUSTMENTS
All transmitters are factory adjusted and pre-tuned to
specific customer requirements. No adjustments are
required by the customer unless a broken part is replaced, a
specific assembly does not display meter readings within
allowable tolerances, or the transmitter is operated at a
frequency or power output different from the frequency or
power output specified in the production test data supplied
with the transmitter.
NOTE
The 24 Vdc power supply is ON when both the
28V supply breaker and ac line breaker are ON.

rated power.
22. Carefully lower the filament voltage in 0.2 volt steps,
pausing about 30 seconds after each step, look for a
greater than 20/0, change in output power or plate
current. This is the filament emission knee. Now raise
the filament voltage 0.2 volts above this voltage. This
is the correct filament voltage for your output power.

when components in the RF circuit are replaced
or when the operating frequency is changed.
Refer to the initial turn-on procedures
(Paragraph 3-3 Steps 19 through 27) for minor
tuning instructions.
The following paragraphs provide procedures for major RF
tuning of the transmitter. If the operating frequency is the
same as the frequency specified in the production test data
supplied with the transmitter, perform the procedures in
Paragraphs 5-9.2, Steps 1 through 10. If the operating
frequency is different from the frequency specified in the
production test data supplied with the transmitter, perform
the procedures in Paragraphs 5-9.1 through 5-9.3.
NOTE
The data presented in the graphs (Figures 5-2,
5-3 and 5-4) is approximate and is intended only
to get the transmitter tuning close.
5-9.1 Frequency Change Adjustments.
NOTE
These adjustments are not necessary if the
related components have not been replaced and
the operating frequency is the same as the
frequency specified in the production test data
supplied with the transmitter.

5-9.1.4 PA Grid Swamping Capacitor.
1. Swamping capacitor A 12C3 consists of two aluminum
plates separated by some distance. The position of the
plate nearest the front of the transmitter is adjustable,
thus making it possible to set the distance between the
two plates. Referring to Figure 5-6, loosen the screw on
the adjustable plate and position it to obtain the plate to
plate sp_acing indicated in Figure 5-6 for the desired
operating frequency. The spacing may be checked by
using a drill bit or a similar device inserted between the
plates.
2. Tighten the screw on the adjustable plate.
5-9.1.5 Cathode Return Capacitor. Cathode capacitor slot
position definition: There are seven capacitor positions
defined for each side of the four cathode return capacitors.
The seven positions are chosen to be easily identified by
eye. The positions are described below and in Figures 5-7,
5-8, and 5-9.
Initially set the capacitor to the nearest whole position
indicated above. The final position of the capacitor may be
fine adjusted for improved efficiency after the transmitter is
operating.
5-9.1.6 Efficiency Capacitor. Preset the efficiency
capacitor A12A3C39 for minimum capacitance. The
capacitor plates should be completely unmeshed.
5-9.1.7 Coupling Capacitor. Preset the coupling capacitor
(Cl) for minimum capacitance. The capacitor plate should
be completely unmeshed. Close the grid compartment door.

procedure allows you to tune the grid circuit using the
output ofthe exciter.
1. Use a coax cable and BNC to Type-N adapter to
connect the exciter RF output directly to the grid input
circuit. This bypasses the IPA.
2. Tum the transmitter plate breaker CB5 OFF.
3. Tum filament and plate control ON. After the filament
time delay, there will be IPA collector voltage but no
IPA collector current. There will be no PA plate
voltage or screen voltage since the plate breaker is

4. Set the exciter RF output level to approximately 15
watts.
5. Adjust the PA grid TUNING and COUPLING
controls for minimum indication on the exciter
reflected power meter.
6. Increase the exciter RF output to approximately 40
watts and repeat Step 5.
7. Turn plate and filament control OFF and remove
primary power from the transmitter. Restore the
exciter and IPA to original configuration. Tum plate
breaker CB5 ON.
Figure 5-10. IPA to PA Cable Length.
5-9.1.10 PA Grid Circuit. There are several reasons for
adjustment ofthe PA grid tuning and coupling circuits, for
example:
A. When the IPA module fails and is replaced.
B. When the tube is replaced.
C. Ifthere is any reason to suspect that there may be a
bad load on the IPA or if changes have been made in
the PA grid circuit.
When the IPA internal VSWR protection circuits are active,
the IPA output power will be reduced and the fault lamp
illuminated. This can make grid tuning difficult ifthe grid is
far out oftune. The 802B Exciter can be used to adjust the
grid circuit to approximately correct tuning and coupling
positions. The 802B Exciter has a reflected power foldback
circuit that limits the reflected power to a safe level for the
exciter regardless ofthe VSWR presentcd to the exciter by
the PA grid circuit. The first six steps ofthe following
Change 3
NOTE
The PA tube input impedance decreases as
the grid input power is increased. The grid
tuning and coupling must be readjusted when
the IPA is reconnected and the IPA output
power is increased to normal.
The following steps shall be perfonned starting with low
IPA output power and zero or minimum plate voltage.
Adjust grid tuning and coupling as drive power is slowly
increased until nonnal drive power is reached and then
slowly increase plate voltage while adjusting the grid tuning
and coupling until normal operating plate voltage is
reached. Keep the IPA reflected power to a minimum while
making adjustments to IPA power output and plate voltage.
8. Restore primary power to the transmitter and turn the
filament control ON.
9. Set the exciter power output adjustment fully CCW.

10. Mute the exciter. Turn ON the plate control and
reduce the plate voltage to zero or nlinimum \vith the
manual power control.
11. Unmute the exciter. Slowly increase the exciter output
while watching the IPA reflected power. Do not let the
IPA reflected power exceed 60 watts.
12. Adjust the PA grid tuning and coupling for minimum
IPA reflected power as the exciter output is increased
to nonnal. DO NOT exceed 35 watts of output power
from the exciter. The nonnal range ofIPA collector
current is 15 to 20 amperes.
13. Slowly increase the plate voltage with the manual
power control. Notice that the IPA reflected power
will increase as the plate voltage is increased. Adjust
the grid tuning and coupling to keep the IPA reflected
power at minimum and IPA forward power at
maximum as the plate voltage is increased toward
maximum.
14. This completes the adjustment procedure. Restore the
transmitter to normal configuration.
5-9.2 PA Tuning and Loading.
1. Press PLATE OFF and FILAMENT OFF switches on
control panel AI.
2. Ifpossible, connect the transmitter to an RF
Wattmeter/dummy load combination or a calorimeter
capable ofmeasuring and dissipating 35 kW at 88 to
108 MHz. Ifthese devices are unavailable, refer to the
RF OUTPUT on the control panel for measurement.
CAUTION
DO NOT PERFORM THE REMAINDER OF
THIS PROCEDURE IF THE
TRANSMITTER IS NOT CONNECTED TO
AN ANTENNA WITH A 50-OHM
IMPEDANCE OR A DUMMY LOAD
CAPABLE OF DISSIPATING AT LEAST 35
KILOWATTS. FAILURE TO COMPLY
MAY RESULT IN DAMAGE TO THE
TRANSMITTER.
3. Open the plate cavity access door and observe PA
tuning and loading capacitors A12C51 and A12C50.
(See Figure 4-7.) Adjust the PA TUNING control on
the control panel until the capacitor is positioned
approximately mid-range. Close the plate cavity door.
NOTE
An easier way to determine position of
capacitors A12C51 and A12C50 is to look at
the capacitor motor drive units. Each has a
limit switch actuator bar that travels with the
capacitor plate. When it is in the middle of its
range so are the capacitors. Left side and
center rear covers must be removed.

6. Alternately adjust the PA GRID TUNING (AI2C2)
and COUPLING (AI2Cl) capacitors for minimum
reflected IPA reflected power. The power amplifier
grid current should be at least 80 rnA.
a.
b.
REGENERATIVE (Positive Feedback)
PERFECTLY NEUTRALIZED (No
Feedback)
7. Adjust the PA TUNING and PA LOADING controls
for a maximum output power indication.
8. Repeat Steps 6 and 7 until maximum output power is
obtained. If the PA TUNING control encounters an
end-stop while in the LOWER position, lower the
shorting plane and retune. If an end-stop is
encountered in the RAISE position, raise the shorting
plane and retune.
NOTE
Because of the relatively high output capacity
of the tube and the resulting low cavity
inductance, no plate current dip will be noted
at higher power levels. Tuning and loading
should be adjusted in steps for maximum
output power. Perform procedure in
Paragraph 3-3, Step 25, for best efficiency.
9. Check for power amplifier neutralization. Refer to
Paragraph 5-9.3.
NOTE
Compare the transmitter operating
parameters with those in Tables 3-5 and 3-6.
Some fine tuning of the previously preset
adjustments may be needed to bring operating
parameters into agreement with those found in
the data. If efficiency needs improvement,
adjustment of the efficiency capacitor
(A12A3C39) may be needed.
10. Press the PLATE OFF and FILAMENT OFF switches
on control panel AI.
11. Determine if plate tuning capacitor A12C50 is
approximately halfway between its limits.
12. If plate tuning capacitor A 12C50 is not approximately
half way between its limits, adjust the PA plate cavity
shorting plane (Paragraph 5-9.1, Step 1) and repeat
Steps 3 through 12 of this paragraph.
5-9.3 PA Neutralization.
The power amplifier of the transmitter can be found in one
of three possible states of neutralization (neut). These are:
c.
DEGENERATIVE (Negative Feedback)
The state of neutralization can be identified by observing
the control grid current while raising the plate tuning.
If Grid Current
Rises
Doesn't change
Drops
Experience has shown that it is best to adjust the
neutralization slightly beyond the point of perfect
neutralization into the region of degeneration. Moving the
neutralization bars out slightly, 1/16" to 1/8", from the point
of perfect neutralization will place the PA into the
degenerative region.
NOTE
State Of Neutralization
Regenerative
Perfect
Degenerative
Check the transmitter for proper neutralization.
If neutralization is correct, do not perform this
procedure.
1. Press the PLATE OFF and FILAMENT OFF switches
on control panel AI.
2. Open the PA cavity door. Short all high voltage
terminals with grounding stick.
3. Remove front half of tube air guide to gain access to
screen sliders.
4. Refer to Figure 5-3 and adjust the screen sliders L N1
and
L N2
• The sliders should not require an adjustment
greater than ± 1/4 inch from the initial setting. (A setting
on the plus side is preferred.)
5. Install the tube air guide.
6. Close the cavity door and apply power to the
transmitter.
7. Check for proper neutralization again. If incorrect,
repeat Steps 2 through 6.

PRODUCT SERVICE BULLETIN
EIMAC 4CX15000A, 4CX20000E, 4CX25000C AND 4CW30000A TUBES
JUNE 22, 2007
EIMAC has learned more about the best way to operate these tubes with regard to filament
management. These operating instructions can be found in EIMAC Application Bulletin AB-18.
Specifically, you should lower the filament voltage after the first 200 hours of operation. After
operating a new tube for 200 hours, the filament voltage should be reduced to the power
emission knee required for your output power.
WARNING
HIGH VOLTAGE IS USED IN HIGH POWER EQUIPMENT. HIGH VOLTAGE CAN
CAUSE SEVERE INJURY OR DEATH. INSURE THAT ALL CIRCUIT BREAKERS
ARE OFF AND PRIMARY POWER IS DISABLED WHEN MAKNG ADJUSTMENTS
INSIDE THE TRANSMITTER.
DISCHARD ALL POWER SUPPLIES BEFORE MAKING ANY ADJUSTMENTS.
INSTRUCTIONS
First, stabilize the new tube emission by operating it a rated filament voltage for a minimum of
200 hours. With the transmitter in manual power control at 100% power, carefully lower the
filament voltage in 0.2 volts steps, pausing for at least 30 seconds after each decrement, until you
see a significant (greater than 2%) change in power output or plate current. This is the filament
emission knee. Now raise the filament voltage 0.2 volts above the knee voltage. This is the
correct filament operating voltage for your power output. Operation at this reduced filament
voltage insures maximum possible tube life.
Recheck the filament knee voltage again after 24 hours to determine if the emission is stable. If
not repeatable, repeat the derating procedure again.
Please contact Continental Electronics Field Service with any questions or comments.
