While it was a busy day on the airways (radio wise) I had the same
result; ATC said scratchy but readable at 15 miles. Tried twisting my
arm around the back of the seat to use the rear PTT but it was too
painful while wating for the frequency to open up. I did try calling up
another aircraft at an airport 55 miles away and they reported 'loud
and clear' (this was on 122.9). I can't believe it's a frequency range
thing on two different radios and different antennas.

Maybe the FAA needs to look at their receivers! or they could have a local
strong signal causing desense.
