[Elecraft] k3 being turn on when N1MM is activated

[Don Wilhelm]

Jerry,

That connection to pin 8 of the AUX I/O is most likely the problem.
I don't know how you have implemented it, but it should not be held low 
constantly.  See Remote Power On in the manual.

Also be aware that when the computer boots, it will "exercise" the pins 
of the RS-232 ports, causing the signal to ground AUX I/O pin 8 to 
become active. That too may be part of the problem.
