I know we have some "wicked smart" guys here and I ain't one of them, so I am hoping one of them can steer me in a good direction to resolving an intermittent static issue I'm having with both of my comms. Here's the details as I have them now:
1. Static happens intermittently and both comms pick it up as evidenced by the RX symbol illuminating on the comm display. Sometimes only the 650 picks it up and sometimes it's both radios. I can go for as long as an hour without hearing anything and then it starts and might last for a few minutes
2. Turning off equipment one by one, including the alternator, doesn't help.
3. I get it on the ground sometimes so I'm discounting static buildup on the airframe
4. My transmissions are strong.
5. Others flying near me don't hear it
I was planning to pull the floor panel up and check the grounding to the antennas, but beyond that I am at a loss to figure out what to look at. Any ideas? If it matters, the coax is RG-400 and the antennas are Don Pansier's Delta Pop Red Tip. When I installed the radios, I did check the SWR to make sure the connection was good and it was, at least back in the 2015 time frame.
Any and all ideas are welcome....thanks!
