I have been wanting to try the JT65 and other modes on 6 meters. Thought it would be a simple setup but its not working. Good audio coming from the computer Line out and going to the K3 Line in. set for VOX operation, mic and Line set on. USB is the mode. Radio will not key up even though

USB is the mode. Use DATA A - set audio input to Line IN once you have selected DATA A, then adjust VOX gain to trip when the JT65 audio is being generated. You will have better results if you use a serial port or USB to serial converter with a single transistor driver on the RTS line for

Hello Jim, Most of us EME types have sequencers, external preamps, and numerous old coaxial relays. While the TX delay built into the K3 may be fine for its own switching, and even for modern QSK amplifiers, there is a great amount of relief knowing that WSJT will switch everything well
