MIm20c Posted August 31, 2017 Report Posted August 31, 2017 I recently purchased a new headset that works perfectly except when I push to transmit. Tried it on both copilot and pilot side. Also tried three different headsets and they worked great. I'm starting to think it is defective but wanted to ask if I had a setting wrong on the audio panel.
carusoam Posted August 31, 2017 Report Posted August 31, 2017 The key function is called side-tone... Setting the side-tone function properly should help with this challenge. Could be related to the radio, audio panel, or something else. Hope that gets you going in the right direction, while waiting for somebody with knowledge. Best regards, -a- 1
RLCarter Posted August 31, 2017 Report Posted August 31, 2017 Try the headset in a different aircraft and see if the is true, my bet is they are bad 1
MIm20c Posted August 31, 2017 Author Report Posted August 31, 2017 The strange thing is it works great on the intercom. Sounds like the internal wiring is more complicated than I gave it credit for.
RLCarter Posted August 31, 2017 Report Posted August 31, 2017 When you say it doesn't work, are talking about the side tone is there or what?

I'm pretty sure I still hear the side tone but my mic acts muted when I push the transmission button. Tried DC 13.4, telex 50d, and Bose A20's at the same time and all worked flawlessly. Emailed the company and was told it was probably in my wiring or setup. Only thing they would do is refund my money when I shipped them back. I really want to give the new set a fair trial.
carusoam Posted September 1, 2017 Report Posted September 1, 2017 It may be a good idea to check in with an avionics shop with this one. Somebody familiar with setting up the side tone with the avionics that you have. An example of a messed up side tone that I have in my ship... when the copilot pushes the PTT switch to broadcast on the radio, the pilot doesn't hear the The co-pilot broadcast. All other times, the intercom works perfectly well. Everyone converses without any issues... usually, my copilot never pushes the button. Some headsets are wired differently as well. For some reason there isn't a standard that works with everything... It was probably DC and BK that set a defacto standard 40 years ago... you would think the headset company would know this and tell you how to get it set up properly. We have a couple of headset guys on MS. PP thoughts only, not an instrument or audio guy... Best regards, -a-
RLCarter Posted September 1, 2017 Report Posted September 1, 2017 If the side tone (being able to hear your transmissions) is there on the other headsets, the new headset is at fault

Both the pilot and copilot can hear the side tone transmission almost as clear as the intercom. This is true for both PTT switches. 56 minutes ago, RLCarter said: If the side tone (being able to hear your transmissions) is there on the other headsets, the new headset is at fault This is my opinion as well but I don't understand how it can work for the intercom and not transmit. 38 minutes ago, Andy95W said: -Have you tried your new headset in a different airplane? -Even though it doesn't sound right, does it transmit to other airplanes okay? Trying a different aircraft tomorrow. No transmission, talking to ground 50 ft from the tower. If I yell loud enough they can probably hear me inside. 1

whiskytango Posted September 4, 2017 Report Posted September 4, 2017 If you have had any recent work done at the factory on a Garmin 430, 530 or 480, they may have reset the audio Gain setting to a point that your transmissions are too weak to be heard by ATC. The problem may be in the radio instead of the headset. This can be a problem with Bose headsets in particular, according to my avionics shop. 1

Tried the problem headset in a factory wired Mooney 40 years younger this weekend. Identical behavior so I'm convinced it's in the headset. I'll try the company again to provide a new replacement and report back with the results. 1
