[Elecraft] serial cable connected to the K2 by accident

[Don Wilhelm]

Werner,

If the computer remained off during the time the serial cable was 
connected, no damage would have resulted, but if the computer was turned 
on and the pot was active, quite a few components could potentially be 
damaged.

A couple of years ago, Tom Hammond (N0SS) published a list on the 
reflector of the potential components that could be damaged, and that 
list may still be available in the archives.  In the worst case, 
anything connected to the AUXBUS, VRFDET, 8R and 12CTRL signal lines in 
the K2 are at risk.

If your K2 still works, there is a chance that no damage occurred.

73,
