[Elecraft] KAT100 - Reluctant to come on, K2 often displays "not inst"

[Don Wilhelm]

Bill,

Fine on the power sequence, but the Not Inst message indicates that 
either the Control Cable to the K2 is not fully plugged in (check both 
ends) or the cable has a bad connection, or that the firmware in the 
KAT100 is not being recognized.

You should tighten the cable jackscrews to check the first, and for the 
last situation, try reseating the firmware IC in the KAT100.
