The Pegasus does work well for PSK31 but you can't use VOX to switch to
transmit. The Pegasus VOX is done in the DSP chip so the output of the
soundcard has both TX and RX audio. The antivox will not work and the TX
get tripped on RX audio peaks. I am using manual PTT but plan to hook up
transistor to switch the PTT via a comm port.
