Had a strange thing happen today. Repeater wouldn't respond
today...so I went to the site. Noticed the COS light was on...but
nothing coming through the local speaker. Checked voltage at the
repeater itself and it was showing 9 + volts. Disconnected the cable
between the controller and the control head (using a converted GE
Mastr II mobile and getting connections out of the control head).
Still had voltage. Had a hard time of rxing a signal into the
repeater itself. Almost sounded off freq. Had to get in real close
to the rx port (disconnected from the cans) to get a clean signal in.
Using a 5c Icom and it was 20 to 25deg.s outside. Probably 30 to 35
in the shack (great insullation...no heat). Ran home got a hair
dryer. Put the volt meter on the CAS pin...still showing voltage...2
seconds of a hot hair dryer...went to zero volts. Took the Icom and
put it in front of a fan to cool it down...got it real cold...put it
back in...voltage stayed the same..zero. Worked fine after this.
Left the shack and it had gotten to about 50 deg.s in the shack by
that time.
Realize the Icom is probably not the problem....but any ideas?
Thanks,
Robert
