This is NOT another "Which Headset" thread.
I've been through 3 sets of PA17-71's (in a year) and am currently trying out the PA17-79 as I keep getting a persistent problem.
After approx 30-40 minutes of a flight I get a very high pitched electronic squeal in my ears and the
only way to stop it is to turn the set to passive.
At first both Pilot Communications and I thought there was a fault with the headset and they exchanged it with no problems. Then... when the same thing happened with the new set, we thought it could be an intercom issue with the airplane, so I then swapped my lessons around 3 - 4 different PA28 Warriors. Same thing.
Pilot upgraded the PA17-71 to a PA17-79 which I immediately charged up, and tried this week end - guess what - same problem.
Are there any headset electronic "experts" out there who've got any bright ideas??
Pilot sell 1000's of this type of headset and have done for years...so we just don't understand what could be causing the issue.
and....I just have to say that Pilot communications have given me absolutely fantastic customer service throughout this little experience -
nothing has been too much trouble
.
PS - I don't want to give up with them because, quite frankly, the headset is the most comfortable I've tried - no clamping, no head aches.
