[Elecraft] K3 RIT & OFFSET ENGAGES AT RANDOM

[Bob McGraw K4TAX]

I speculate two issues, RFI usually due to CMC.   For 160M one should 
employ a good common mode choke on the feedline at the antenna feed 
point and another at the radio.    See the research of K9YC on this 
topic.    Secondly, a logging program issue. N1NM has been documented to 
occasionally have this issue.   And it may be the first issue, CMC, 
causing an issue with the computer.

FYI - I despise all logging programs as I find them more of a PITA than 
efficient use.
