If we are talking about the same squelch, it should have no effect on transmit. Its only function is to activate the speaker when the received signal exceeds a certain level, sort of like VOX in reverse. The radio should switch to transmit when Digirig activates PTT. You can simulate that using the method discussed here: > [@Homebrew cable PTT issues](https://forum.digirig.net/t/homebrew-cable-ptt-issues/248/2): > > Leo, In your case as well as in any other situation where PTT by RTS is not working as expected, the first thing I recommend is testing the cables by simulating Digirig’s PTT action. There is a quick and dirty method for that: plug the audio cable on the transceiver side unplug the other end of the cable on the Digirig’s side electrically connect sleeve to the nearest ring on the Digirig’s side [image] If radio keys up then the issue is on software/Digirig side. If radio doesn’t key up then… To confirm that there is audio output from Digirig, you can just plug regular headphones into the audio socket and you should hear the sound on one side during the transmit frame. --- _[View the full topic](https://forum.digirig.net/t/ft3dr-transmit-issue/911)._
