Everyone is trying to provide a technical solution. Kudos.

Now just go out and buy (or try to find a used one, which is more like it)
the HS61(? I think- mine's in the flite bag) headset adapter that Icom made
for interfacing aircraft headsets with the A21. Works great, but that was
the biggest problem with an otherwise good aviation band radio- all my Icom
ham accessories work fine- just have to have the headset adapter....They
solved that with all the followup models.

Folks - I'm having difficulty getting audio from my Avcomm headset to
my Icom A-21 handheld.
The Icom requires a condenser microphone and the Avcomm has an
'electret' element, which as I understand is a variety of condenser
mic.
Has anyone had a similar problem and how was it solved? - Mike

PS- I see a variety of circuitry on the 'net describing how to power
the microphone, but I was hoping not to have to go off building
another box.
