[Elecraft] K2 auto-detect feature

[Lou Roux]

Hi guys,

This discussion reminds me of something I've been wanting to for a 
while. I don't use the internal keyer in the K2 but prefer my
own keyer and I'd like to parallel my computer/cw keyboard with it. What 
kind of circuit would this require or could I just parallel
the lines together?

Thanks,
