I have a loud scratchy sound when I PTT.
Here is what I have
Garmin 240 audio
Garmin 430
Garmin sl-40
Quiet Tech halos
Dual lightspeed Ign.
When I select both radios and PTT the 430 I hear it in my headset but the transmit is clear, when I deselect the SL40 it goes away and the same when using the SL40 only. I sent the 240 back to Garmin where they bench tested it and could not reproduce the issue. The problem only shows when both radios are selected and the PTT is used, otherwise they each work perfectly.
I rerouted the Coax and upgraded them to RG400. No change
I called Garmin and they suggested looping the two radios together to kill the transmit on the non Tx radio.
Any suggestions? Ill try anything
