[Elecraft] K3/K2 and N1MM logger

[Ed K1EP]

In anticipation of my K3 with N1MM logger, I would like to build any necessary interfaces (keying, amplifier, computer control, etc.).  I have heard that the interfacing is similar if not the same as the K2, but I don't have a K2.  So, I would like to know how you are interfacing your K2 to N1MM.  I don't mean "I built a serial cable myself" or "I recommend xyz's brand".  I would like to know more about your configurations, like whether you are using a footswitch to key the K2 which then keys an amplifier.  My first big intended use of my K3 is in an SSB contest/MM environment with amplifiers, (if I get it in time for CQWW SSB, I am not complaining, I just want to be prepared so I can use it!)  I only have 4 or 5 weeks before I am traveling for the contest, so I want to get building!  Reply to me direct or to the list.  Thanks.
