I'm using it with DTR keying. I've set CONFIG: PTT KEY to OFF-DTR and I have set N1MM to 
key via the DTR line. I allow the VOX to do the t/r switching; it works with semi- and 
full QSK. No connection is needed except for the regular RS232 cable between the computer 
and the K3.

The only gotcha is that during bootup the computer toggles the DTR line several times. So 
between contests I turn the CONFIG parameter off; and when it's on I'm careful to set TX 
TEST whenever I boot the computer.

I'm using a 2.5 GHz single-core cpu running XP. I have absolutely no problems with the CW 
generated by N1MM, but I don't use spotting or SO2R or anything fancy.
