I seem to recall that the trick to doing this (other than diode steering the PTT's and isolating the audio) was to steer the PTT signal from each TNC to the other's RF-DCD port through a diode. That way, each TNC would know when the other had the PTT in use. This was most commonly used to mux 1200 and 2400 baud users on a single channel. Of course, your TNC would have to have the RF-DCD port (the fifth pin on a TNC2 clone) available, not all do..~Steve>

Does anyone remember such an article an either have a copy or point me to a site where I can download it? Thanks, Dave, WA6IFI
