Well, I’m hoping that some really smart person can figure this one out…. About a year or so ago I started having intermittent radio static across some frequencies. I have 3 G3X touch with a GTN650 comm1 and a GTR 200 Comm 2 and a GMA 245 audio panel. It sounds like the squelch needs to be adjusted but the G3X touch has auto squelch. Its loud enough that it is very uncomfortable. On long cross country flights it may only happen on one frequency. For example yesterday I flew from Colorado Springs to Carson City, Nv and it only happened on one ATC frequency. It’s across both radios and when I turn off the audio panel, it still comes through the GTN 650. I tried seeing if it was in some frequency range but I don’t see any pattern. In fact it changes, for example, last week I flew into Charlotte, NC and I had heavy static on the approach frequency, but the next day when I flew out I had no static on the very same frequency. I think it started when I changed out my magnetos for PMAGs but Brad claims that there isn’t a problem. I would appreciate any suggestions on how to solve this one.
