Radio stack is:
1. Comm1 - Garmin 530
2. Comm2 - Bendix King KX 155
3. AudioPanel - PSA 6000
Problem: I hear over-powering squelch on the ground or when over-flying within 1300 feet AGL (especially if radio towers around). It is intermittent. I have shutdown each of the above components individually and totally including running the Garmin 530 in "fail safe" and still get it. It sounds like you pulled your squelch knob. It occurs on both Comm1 and Comm2. It seems to improve at altitude. It doesn't matter how long the radios have been on - although it seems worse at the beginning after engine start. I have shutdown EVERYTHING on board trying to isolate the problem.
Not performed: Saw a suggestion I think from weirdJim in another thread to check before engine start (didn't do this).
Hangar buddy suggested it was probably the ELT picking up interference and he suggested disconnecting it and flying it (haven't as I figured something would have to be listed inop or placarded). ELT is the older type and not the 406. Suggestions?
