Thanks Shane. I'll have to look up how to do that on my David Clark sets.

I have a number of different headsets and every so often I would be taking someone for a flight and we would end up with the squeal just as you described. I also had an avionics shop check out the equipment, but they were unable to find anything wrong. After dealing with this a few times I discovered that it was the mic gain on one of the headsets that was causing the problem. I adjusted the gain down on all on all of my headsets and have not had a problem since. Hope this helps, Shane Daly -----Original Message----- From: Danny Sent: Tuesday, May 27, 2014 5:51 AM To: Lancair Mailing List Subject: [LML] Audio squeal This is for all you avionics buffs. I was headed out for an instrument proficiency check last Saturday. As we were taxiing out I noticed what sounded like a slight echo in my headset. My CFII heard it too. It was the kind of thing one hears from a feedback loop on public address microphone. We didn’t give it much thought at first but as we continued talking it got progressively worse until finally it became a squeal whenever we spoke, again, just like a PA system microphone. We played with the squelch, volume, and different headsets, all to no avail. I later found that it isn’t there with only the pilot headset plugged in. It also disappears when I bypass the audio panel. This happened once before several months ago. I had it look at by a reputable avionics shop but they were unable to replicate it and could find nothing wrong with neither my radios nor my audio panel. I plan to have them take another look as soon as they can schedule me in but thought I’d query the list in the event anybody here has any experience in this area. Your comments, thoughts, and consideration are appreciated.
