I have been using Skype for remote receive audio. That seems to work fine except I have to mute the microphone at the remote location to hear the audio from the rig clearly. So that is what I have been doing. But now I want to setup the transmit audio link from the operating position to the Control location.

Using a simple audio transformer on the PC at the Control position provides audio that sounds great. Only problem is there still seems to be interaction between the send/receive channels on Skype. Is Skype really a half-duplex link? That would actually be OK as the ham rig is only half-duplex. The trick would be controlling the “T/R” switch on Skype so it is in sync with the Transmit/Receive control for the rig.
