I've been playing with FT8 and WSPR with both the BITX40 and ?BITX.? I'm using an easydigi for switching PTT and isolating Rx audio.? I found the loss was too high on the Tx side so I'm going right from the sound card to the rig for Tx.? I set up both my radios with a mono jack for the speaker and TRRS for mic/PTT and corresponding cables on the eaydigi so everything is interchangeable.? I'm using this sound card and this FTDI cable? The audio cables were in my junk box but I think they were from digikey.? I have the sound card and FTDI cable plugged into a small unpowered USB hub with the easydigi hot glued on top with the cables all hot glued for strain relief.? It is ugly as sin but sits out of sight and works.
