Hi there.
Thanks for the reply.
I bought them new, and have the manual. No mention of it.
The signal strength is not the issue. It happens when you are on the ground and in full signal.
New batteries etc etc.
What the problem is - the noise gate that should let go the moment the pilot stops talking, does not appear to be now, so it basically holds my mic open for too long, meaning, I can't hear the other end until it releases. But not sure how to fix it.
The Mic sensitivity is good, as the intercom works perfectly - AND - the first call I made with it was perfect! So not sure what happened.
