[Elecraft] [K2] Random LCD display - Speed and Power

[Don Wilhelm]

Martin,

While that may happen rarely in any K2 - when the firmware is quite 
busy, your video shows it happening frequently, which is abnormal.

The most common cause of that behavior is in late K2s with the new 
encoder - the one with the encoder board that sits close to the control 
board.  If that describes your K2, then flush cut the encoder board 
leads (really close to the board) and do the same on the control board 
in the area where the encoder board can contact the solder side of the 
Control Board.

If your K2 has the older encoder, then look for a bad solder connection 
on either the Control board or the Front Panel board.
