Hello Scott,
Maybe you can answer the following question or ask one of the other
technicians for the answer.
I have a 580 Delta transceiver. I recently found a noise blanker
and installed it. While installing the noise blanker, I accidently
bumped the final bias adjustment pot, R23, which is located just above
where the N/B PCB goes. I later noticed that the transceiver was
drawing close to 7 amps of current on key-down/PTT with no signal. That
certainly didn't seem right.
I adjusted it back to around 1.5 amps so the finals aren't drawing so
much current, but I can't find anywhere in the 580 Delta manual what the
proper setting is for the final bias adjustment.
Any help would be appreciated. I have also copied this to the tentec
enthusiast reflector. Possibly someone there knows the answer.
Thanks,
Lynn Stolz N8AJ - lstolz@tekelec.com
