computer dumped him, so he went
outside the house where he knew he
could bypass the computer and tried
•• result, another dump •• so he "went
three miles away and tried to make a
call to El Cajon from a telephone
pole •• AND FAILED. When he came back
15 minutes later he was quite
impressed with our ability to DUMP
un-authorized calls. So much so that
he called his supervisor and after
five minutes of discussion they came
to the conclusion that their master
computer must have a "glitch"
causing the problem since all calls
were for one minute. One second will
show as one minute on your bill.
This now makes your editor
wonder about all of those ·one
ringers· we have been getting in
Valley Center the past year with no
one on the other end and the
unaccounted calls on our phone bill.
Are you getting one and two
"ringers· with nothing there when
you answer? Are you finding calls on
your bill that you did not make?
This gremlin is making money for Pac
Bell!

Work parties at the repeater
site are a lot of fun ••and besides,
it is a good chance for you to see
the repeater site and all of the
equipment which you use ••you can
learn quite a bit too.
(7-9) Jerry-WB6FMT met Mike­
KC6KCQ at the repeater site to work
on the 449.425 repeater while Stan­
W9FQN worked on the tower mounting
brackets for the new tubular tower
crank-up. Jerry and Mike put the
repeater back on the PL access mode
but failed to find the distortion
although the problem has been
limited to 4-5 components which are
slowly being replaced.
(7-11) Mike-KC6KCQ took the
449.425 repeater home and after four
hours found the reason for the bad
audio. Because of the way Motorola
operates the audio output
trans1stors in the transceiver (not
normal) we inadvertently grounded
out the negative side of the audio
when the autopatch system was
connected. Audio and tone reproduction
is greatly improved. This
problem won't happen on the next
repeater constructed! After several
other minor mods the repeater was
returned to service 7-13.
(7-14) President Harry-WA6YOO,
VP Art-KC6UQH, and Stan-W9FQN
visited with Joe Crowder who runs
the Santee, Escondido, and Oceanside
swap meets in the San Diego Co.
area. Joe recently added another
Computer. Electronics. Ham Radio
Swap Meet to the Santee area on the
third Saturday and wants to add
another one on the 2nd Saturday in
Oceanside to start in October. Joe
was advised of the weekends of ALL
swap meets in Southern California
but was adamant about his selection
of the 2nd Saturday. For the
present, PARC will publicize the
swap meet in the SCOPE and make
available 146.73 for "talk-in" to
the Oceanside swap meet at the
outdoor theater on the north side of
road 76.
Your editor is reminded by OT's
that around 1980 PARC sponsored the
only monthly ham swap meet (PARC
called it a "Flea Market") in SDCo.
which was held at the SWAN parking
lot just a few miles from the
Oceanside drive-in on Rd.76.
(7-19) John-WB6IQS and Stan­
W9FQN visited the repeater site to
l)temporary switch of 146.730 and
147.130 antennas and feed1ines Which
resulted in the .13 machine sounding
weak like the .73 •• so we do have an
antenna-feedline problem on the .73
repeater. 2)added 7ga1 of distilled
water to the 3.300 AHrs of emergency
batteries (14 batteries' .5ga1 each
seems like a lot of water but these
are big batteries, 3501bs, and we
were still .25" above the add mark),
3)attached hardware to angle iron
posts for the new tubular crank-up
tower. and 4)new DC connections
started to the new 3.300AHr battery
backup system. John also left some
parts for Mike-KC6KCQ to use on the
new .73 repeater.
(7-25) Jerry-WB6FMT and Stan­
SEP'92
W9FQN visited Del-WV6Z's MMSA and
Kerry-N6IZW's LMSA autopatch
centers. Both units were installed
with battery backup, placed in
Motorola cabinets, prepared for
unlimited 911 calling time (cannot
be activated yet), and earthquake
proofed. The LMSA patch was adjusted
to give a dial tone almost
immediately like the VSTA patch
••and we forgot to adjust the MMSA
patch access time.
(7-28) The 449.425 repeater
dropped in Signal strength and Mike­
KC6KCQ went over after work and
found a connecting coaxial cable
with an internal open but suspect
another problem now in the
transmitter. This cable will have to
be replaced with another cable of
the exact dimensions as the old
cable since it is one leg of a "T"
where the antenna connection sp11ts
going to the rec1ver and transmitter
cav1ties (filters).
(7-29) Stan-W9FQN held a
meeting with Doug Garton to discuss
the club's property 11nes and
easements. Doug, who owns property
on two sides of the PARC repeater
s1te. provided the club with several
survey maps which will be kept in
the club files.
(7-29) Mike took the .425
repeater home to try to find why the
final transistors were shutting down
on transmitt.
(7-31) Mike found an original
transm1tter internal connection with
a rosin core joint which has been
there since the transmitter was
constructed. After soldering, things
seemed to be working normal. The
repeater was returned to the bunker
7-30 in What we hope is working
order.
(8-3) Stan-W9FQN went to the
site and took the 146.73 antenna
rated at 9db (4 folded dipoles
bought in 1973 used) and replaced it
with a 2m corner reflector rated at
8.1db. Previously the .73 repeater
was 6db below the .13 repeater and
now it is 4db above the .13 repeater
for a relative gain of 10db Which is
available on transmitt and rece1ve.
