[Elecraft] (Elecraft) K2 Build #7552

[Don Wilhelm]

Kevin,

You have a K2 with the new encoder board.  If the leads on that encoder 
board and the area of the Control board directly behind it are not flush 
trimmed (really, really flush trimmed), the two will make contact and 
'strange things will happen'.  Yes, the tools list does not include 
flush trimmers, but you will need them.
Inexpensive flush trimmers can often be found in the electrical tools 
department of your local DIY store (at least here in the US Home Depot 
carries them) - look for Xcelite (or Lufkin or Cooper) 170M - it may be 
packaged with a pair of small needlenose pliers.

Try putting some insulator between the encoder board and the control 
board to test and see if that cures the fault condition.  There is not 
much clearance and you may not be able to put the screws in the control 
board while doing that test.

73,
Don W3FPR
