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.
