WB2CBA's post did not include "CAT" - just PTT through VOX.?
If you are just interested in PTT, I'd suggest USB sound cards with GPIO.?
? ? A much simpler (resistor and transistor) PTT solution which is support by most digital applications.
The digirig-mobile DOES include real CAT control.?
With that your computer can control the freq/band and any other settings that are included in CAT commands (including selectable filters, etc.).
Very reasonably priced as well!
Only down side I see is that it appears the sound card input is mono.
I have an old MicroHAM USB Interface III from about 2008 which had sound card and CAT capability.? Not sure they are around any more.
I paid a lot of money for it!?I haven't used it in years.??Gave up on it when Windows stopped supporting the USB driver.
? ?I wonder if newer Windows versions would work with it.?
? ? I'll have to give it a try.
