[Elecraft] SN# 2602 (Alignment & Test part 1)

Tue May 14 07:43:02 2002

Mike:

Check to confirm that you have the plug where the FCRT probe connects to 
the Control Board wires properly. It sounds as though you may have the two 
pins swapped and that the center conductor is GROUNDED while the shield 
thinks it's the hot lead.

Shield goes to the pin whic is closest to the edge of the PC board.
