I'm just getting stuff ready for the CQ WW VHF Contest and find that I can't
key my K2 IF radio with WSJT-X 1.7.0 the same way I do for WSJT 10.0. That is
to say, I have used the DTR line from a USB-serial converter to drive a
transistor switch which is connected to the mic jack PTT input. Works fine in
WSJT but I can't get it to work in WSJT-X. This is a basic K2 with no computer
interface, so I have the CAT rig set to "none". Does that turn off the DTR PTT
function in WSJT-X?
WSJT-X does work with VOX PTT, but DTR would be cleaner.
I have had WSJT-X running ok on HF JT65A when I used a K2 with a computer
interface. I don't recall but perhaps the PTT was thru the CAT interface in
that case.
Any suggestions as to what I may be doing wrong?
73,
Steve VE3SMA
