This is for a ICOM A200 com but any advice would be helpful.
After converting one of my two H10-13.5 headsets to ANR the sidetone is brutally loud when tranmitting. We are aslo getting loud background hissing/static when using the intercom.

I was told to adjust the sidetone (to lower transmitting feedback signal) but am not sure how much. I am aslo not sure how or when to adjust the mic gain.
What does it do?
Are they related?
Thanks greatly, as you can tell avionics are not my forte.
Regards
Rick
