[Elecraft] K3 does not change mode properly with band change

[AB1DD]

Dave,

Do you have anything plugged into the K3, like the RS232 connection on 
the back? Any software running? Try the radio with out anything that 
might take control and see what happens.

Resistance is futile.
(don't know about reactance, though)
