Don's fixed level audio output is "what the doctor ordered" for digital receive. Couple that with a small SPDT reed relay to switch audio input between the mic and a separate AFSK/PSK/JT65A/etc audio input and drive the relay with a "Digital PTT" input and you have the complete "no cable swapping" solution.
