[Elecraft] K3S, VOX and WSJT-X?

[Frank O'Donnell]

Rich,

I don't think CAT control is necessary in this case, because in this 
configuration, all of the tx/rx is on one band (630m) and one frequency 
(474.2 kHz, used by JT9, WSPR and other digital modes, unlike HF bands 
where they are on different frequencies). I haven't yet found anyone 
else with a K3/K3S operating in this configuration on that band, but a 
number of ops with other brands of rigs set things up this way, with 
several decoders running all in VOX mode. I assume there must be a way 
to do this with the K3S.

Thanks and 73,

Frank K6FOD
