Here is one for you guru's and BMOC problem solvers. Must admit there are a
lot of good ones in this group. A 2 meter repeater 15 miles away using a
Mastr2 PLL exciter emits a carrier drop pulse of about 500 ms in duration
on a frequency 225 khz down from the repeaters xmit freq. Unfortunately this
pulse is on the output of another repeater I continuously monitor. The repeater
trustee is very knowledgeable and cooperative and is attempting to solve this
problem. He did say the PLL is not quite 5 volts but otherwise seems to
work well. The drop pulse on COR is definitely coming from the
exciter and can be observed on a SA with PA installed and removed. It
was replaced with another exciter and the second exciter is doing exactly
the same thing.
