Hi
I have now 60h on my -10 and suffer of bad noise of my COMM 1 GNS430W.
It is constantly receiving loud noise when the engine is running. Often it is ok on my home frequency 122.15 but permanently noise is present on 124.xxx frequencies.
The COMM 1 is connected to a belly mounted Comant C-122 antenna which is attached by screws and nut plates. The antenna came with a cork gasket which I used.
Here are my set of questions. The radio receives fine when engine is not running, so I guess that grounding of antenna or cabling should not be the cause of the issue. What could be the potential source of the noise? How can I identify it?
I took all electric circuits one by one off-line without success.
Any ideas are appreciated
Thanks
Mike
