Jay, just for you I tried out a little test this morning on my flight to
Martha's Vineyard. I borrored a friend's Arrow, which has
Narco CP-136 audio panel
Narko Mk12D nav/com + IDxxx (Integrated DME)
Garmin 300XL gps/com

As I arrived in the pattern, I had the ATIS on com2 and tower on com1.
I had the "COM1" button pushed in. I pushed in the "BOTH" button and
verified that I could hear the atis. I shut off the "BOTH" and I
could not hear the atis on top of the tower freq.

When I left I switched radios (ATIS on com1, tower on COM2), with the
same results: the radio switched out on the audio panel can't be heard.

I'm not sure what this means to you - you DID want a new audio panel,
didn't you?
