[K2] [Elecraft] K2 Trouble Shooting

[Don Wilhelm]

Michael,

You apparently are having some kind of problem with the AUXBUS signal 
inside the K2.
I doubt if a reset will do any good, but if you want to try it, record 
all your menu settings (including all the filter settings) before doing 
the reset because the reset will restore all those settings to factory 
defaults.  If you wish to proceed with the reset, hold the 4, 5, and 6 
buttons down while powering the K2 on.

I would rather suggest that you reseat the microprocessor chip (control 
board U6) and the options that are not being recognized.  I am mystified 
because you did not say you were getting any INFO 080 messages which are 
the most common result of an AUXBUS communication failure.

73,
