Bob,
Success!
I thank you for sending me in the proper direction to find this problem. I would never have figured out that it was RF loose in the cockpit. While I was checking for where I could possibly have a loose connection this afternoon, I removed the radio from the tray and measured both the length of the radio and the distance it had to reach to the connectors in the back plate. Whoops! Looks like the radio needs to be seated deeper into the tray!
Stupid builder tricks! When I installed the radio, I installed a bezel around them and to make it look nicer, I put the bezel under the faceplate on the radio. The radio passed the test Garmin has for that, (three turns of the screw after the radio powers on) but apparently over time it got looser and looser and started having more and more symptoms. I modified the bezel this afternoon so the radio would properly seat and the problem appears to have resolved. I was getting a huge RF leak from the back of the radio prior to it getting into the coax.
I am completing my conditional inspection so it will be a few days before I can fly and see just what symptoms I have fixed.
Sounds like the project is moving forward again.
Great! Let us know what you discover. As I recall,
we still have a receiving noise issue that MIGHT
be related to the antenna connector . . . but
probably not. We can tackle that one after
you've had more time to assess the state of
your universe.
