I posted a history of my attempt to fix a problems with my #1 comm. It started breaking squelch over a year ago in the presence of high RF. It got progressivly worse and I've been working on it for the last 5 months.
Well I think it is finally fixed. Or at least very much better. Yesterday's test flight couldn't produce the problem at any of the spots near home. I believe it was a ground. After eliminating antennas, radio itself and other things I asked for more suggestions. Lance and Bill both suggest grounds among other things. I spent last Saturday cleaning and tightening every ground I could find or reach from the engine to the battery. Could fly due to weather and work till yesterday. And lo and behold, no squelch break. I say I believe it was ground because I also clean up the ELT antenna connections. And I couldn't say which ground. I didn't find any overt problems and I didn't take the time to test fly after each cleaning. Anyway, at least I know it can be fixed.
Still frustrates me the shop was ready to blame 'aging radios'.
Thanks for the suggestions.
