ICOM IC-A22 Handheld Transceiver Question

[PropwashPete]

Hi everyone. I am brand new to these forums, so my question my be better asked in another forum, but ya gotta start somewhere.

I have an ICOM IC-A22 handheld transceiver that I want to use as my primary communications radio on my Experimental aircraft. The radio seems to work fine as a handheld, using the built in speaker and microphone. The problem starts when I try to use it with my Telex Status 50 headset. I am using the recommended headset adapter (OPC-499) but the volume through the earphones is very very low. In flight you can not hear anything at all. Also, though the push-to-talk switch seems to trigger the transmitter, the mike does not modulate. No voice is heard by others although they can hear the mike "click" when I press the PTT switch.

Has anyone ever run into this type problem before? ICOM support does not seem to have a clue.

Thanks,

Propwash Pete

Hi Pete, The only thing that I can suggest is check the Batteries, in the headset, they may need to be changed.

Same result with a different headset. This time with an older headset that does not use batteries since it is not an ANL headset. Thanks, grumps96. I'll keep experimenting.

I am not familiar with the AC22,but I know on some of the Icom LMR portables, you set the audio input from the speaker microphone.

I think I have solved the problem. There was obviously a short circuit between the earphones (me). I had some of the switches on the headset set incorrectly. The volume is now normal and it appears my mike is now modulating.

A new problem has arisen, though ... the audio is badly distorted and difficult to understand. There is also a superhetrodyne squeel when I key the mike. This could be a Telex problem and I will contact them.

Thanks for all your help.
