Ron, there is audio out on pin 8 but it is a low level output for a TNC, you would have to use a audio amp to kick it up to drive headphones.

I plugged in my Heil headset which I use on my Icom IC-756 into the mic connector on my Icom IC-910H. I got no audio output on the headset with any SET option that seemed to apply.
I reported this to Heil and got the following reply: "Yes, Ron, they removed the RX audio from this one model, and we're not sure why! No menu thing is available, but there may be a jumper or something inside that Icom can help you find. Sorry about this--it caught us by surprise, as well, that they would change this one model."
The schematic shows a signal AFO going to pin-8 of the Mic connector and the pinout on page 15 of the manual shows "AF OUT (varies with [AF]) on pin 8.
Has anyone used the audio output from the mic connector? Was there any "trick?"
