SantaPaulaCTSW Posted March 21, 2017 Report Share Posted March 21, 2017 Hi Was flying the other day and started getting a background hollow sound in my headset during radio calls when pushing the push to talk button. It is a Garmin SL40. The noise is heard in both the pilot and passenger headsets. I did a radio check in the air and on the ground, and my transmissions are being heard clearly, although one person said they were hearing some noise in the background too. I am hearing other airplane transmissions without this added noise. Just this irritating background noise when I transmit. Tried the squelch, but did not make a difference. Any suggestions are welcome! Thanks! Robin Link to comment Share on other sites More sharing options...
Roger Lee Posted March 21, 2017 Report Share Posted March 21, 2017 The SL40 was supposed to be sent in a few years back to have this issue of superfluous noise taken care of. It was free back then, but you may have to pay now. Call Garmin and ask them. Link to comment Share on other sites More sharing options...
SantaPaulaCTSW Posted March 21, 2017 Author Report Share Posted March 21, 2017 Thanks Roger. I will contact Garmin. This is a new thing. Never had this trouble before. Although the radio is about seven years old now. Robin Link to comment Share on other sites More sharing options...
SantaPaulaCTSW Posted March 21, 2017 Author Report Share Posted March 21, 2017 Hi Roger, do you have a good contact number or person for this issue so I don't have to wind my way through the entire Garmin world? Robin Link to comment Share on other sites More sharing options...
CT4ME Posted March 21, 2017 Report Share Posted March 21, 2017 ... Standard procedure for radios, and almost anything electrical on the CT... Check and really tighten all grounds! Link to comment Share on other sites More sharing options...

Anticept Posted March 23, 2017 Report Share Posted March 23, 2017 If you send anything to garmin, make sure you document every single problem you have with it. It's a flat rate repair. Link to comment Share on other sites More sharing options...
