[Elecraft] K2 and N1MM+

[Bruce Rosen]

Ted -

Ultimately, N1MM+ needs to talk to a keying circuit which will then drive
the KEY IN jack
on the K2.  I've had very good results, for example, with K1EL's
WKUSB-SMT.  I got that when
I no longer had a PC with serial or parallel ports on it.  In an earlier
incarnation, I had N1MM
drive a one-transistor keying circuit that was, if memory serves (it was a
while ago), connected
to a serial port on my PC ... and defined as such in N1MM.

Good luck -
