[Elecraft] K2/100 - "Info 080" message

[Brian Lodahl OZ2BRN]

Hi Tom / Don,

I had a similar intermittent problem, when dissasembling and 
re-assembling my K2 /100 #6936 during installation of the XV-60 module. 
All my efforts attempting to debug the problem were unsuccessful, and in 
the end I suspected that I had killed U1 (or some other PIC) by mistake.

Then - the INFO-080 error surprisingly went away again; as I found that 
the problem dissapeared after properly unplugging and re- securing the 
data bus cable (flat ribbon cable) between the K2 and the KPA 100 again.

Away went the problem and I haven't seen it since ... Only the next day 
after the fix,  the rig took a pounding 48-hour CQWW CQ operation, 
flawlessly.

K2 #6936 and Kx3 # 1118
