[Elecraft] N1MM Com Port CW

[g4mkp]

Sussed! Faulty RS232 lead. It's a wee bit too short and the sharp 90 degree
bend into the rig had caused pin 4 wire to come adrift.

My fault entirely but you guys have been very helpful since having had the
software switches and set-up verified by at least six of you it had to be
the hardware interface - 'when you have eliminated everything else whatever
remains is the answer'.

What is noticeable is the complete lack of EMC issues with serial port cw
keying compared to the homebrew SO2R box which included the parallel port
keying circuit and bucket loads of ferrites. I can now return those to the
storage draws.

Thanks and cheers,
