Simple vox circuit for use with packet (and other data modes).
It means that you can easily adapt handhelds and PC's without the need
for a seperate PTT circuit.
VOX is ok for 1k2 baud packet but I wouldn't recommend it for 9k6 stuff.
Comes as one part of seven plus.
It works by feeding the left hand soundcard audio via one input to be
rectified nd used to switch the PTT whilst the right hand channel is
simply fed via a capacitor to the mic inputfor transmission.
It should be self explanitory once you look at the circuit - if not then
your in the wrong hobby ;-)
