Folks - I'm having difficulty getting audio from my Avcomm headset to
my Icom A-21 handheld.

Your Icom A-21 uses an internal electret mike. There is no reason
your headset electret won't work. I use my headset with an A-3 and it
works fine. Are you sure you're putting the mike about a half inch
from your lips and speaking directly into it?


The Icom requires a condenser microphone and the Avcomm has an
'electret' element, which as I understand is a variety of condenser
mic.

Not true, see above.

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.

Just not true. The only headset interface that I've seen that
requires power is for active noise cancellation.
