N1MM Logger does not support the KY software command that makes use of 
the K3's internal tuner. I believe there are implementation reasons for 
this limitation, in which case it might not be an easy limitation to remove.

You can use:
- DTR or RTS on the radio control port without any additional hardware 
(with some limitations that are described in the N1MM Logger 
documentation);
- DTR or RTS on any other serial port with a keying transistor to the 
K3's key jack; or
- parallel port keying to the K3's key jack (I don't know whether this 
can be made to work under Linux, though - it requires the DLPORTIO 
driver under WinXP).
All of these can be affected by Windows timing problems.

The standard recommended solution is the WKUSB (or a serial WinKeyer), 
which unfortunately requires an extra box.
