Re: K3 interfacing


On my home pc:
I use a straight RS232 cable to DB9 connectors on K3 and pc.
CW and PTT run over pins 4 and 7 of the same cable.
So CAT and PTT/CW over same cable.

On my laptop:
USB-serial converter. CW, PTT and CAT over the same cable, see above

On the club computer when in serious contest:
USB to serial converter for CAT
Second USB to serial converter to an old K1EL winkey (it has DB9 connector) for CW and PTT

Just obtained a used K3. Interested in finding out what are folks using to interface with a PC for CAT and CW PTT ?
