I had some trouble with N1MM at Field Day. I had tested with the  
K2/100 before then, but when I got to the site the night before FD,  
it didn't work. It took a considerable amount of troubleshooting to  
figure out the problem.

Turned out, there were two issues. First, condensation had built up  
in the K2/100 overnight, and this caused several high-impedance  
circuits, like the display and the AGC to malfunction.

Second, the K2/100 wasn't receiving the signals from the laptop. The  
lack of receive was due to two factors - a bit of burnt flux between  
a couple of the DB-9 pins, and an unsoldered pin on the MAX232 chip.  
(!) I'd been using the K2/100 for a year and a half before I noticed  
that.

Make sure the K2 is transmitting and receiving, and the computer as  
well. You can verify that the K2 is transmitting by hitting the  
Display button while the PORT menu is being edited.
