I have had 4 years of flawless operation on my Garmin GPS/COMM 250XL.
Last week I noticed that while approaching my destination I could not clearly hear the tower due to static interference. The tower had the same problem hearing my transmissions. When I landed the tower said I can hear you fine on the ground. And vice versa.
This week I tested it on the ground with my wife using the handheld. Clear.
I then started the engine and tested it on the ground at different RPMs. Clear.
I then took off and tuned in the ATIS nearby and could barely hear due to static. I then flew back to my home airport and called my wife on her handheld while in flight, static again.
Landed and the comm was clear again. I'm now thinking it may have something to do with the Comm antennae.
What do the experts think? Any helpful suggestions would be appreciated.
