I believe there was an article in QST within the last three months
describing the aircraft interface. It needs power for the mic. The
interface hasn't changes for a long time and you can still use a carbon
mic., so it provides a fairly high level output.

Hi to all,

Someone offered for an reasonable price an Aviation Headphone / Mic
(Avcomm). Noise canceling for the headphones by beeing very closed
earcups and something like a 'noise reduction chip' in the Mic.

Are those devices useable for Ham Radio?

Anyone ever tried this with an ICOM or Yeasu tranceiver?

Any comment is welcome!
