It is very strange. As I said when I used Vara sound card settings where QMX was mentioned as output/input device TX power was very low. Than I decided to choose mic and dynamics as input and output device in VARA soundcard settings. And TX power became normal! Around 40 Volts peak to peak. Ans VOX was OFF! So I transmitted some signal, but I am not sure what signal it was? and was it not distorted or not. At least I didn't manage to make a connection.?
I tried to switch VOX on and found out that it doesn't work. Even during normal SSB communication it doesn't activate TX. So now I am really confused....?
One more question. There is no Kenwood 440 in VARA list of transivers. So I've chosen Kenwood 550. Is it OK?
