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
