Roger, The bottom line is that you have to end up with one lockwasher between the standoff and the board. It matters not which end of the standoff that occurs on - the lockwasher adds a bit more length to the standoff and it is sometimes needed to assure adequate clearance for the board above the BNC connectors.
There is one other consideration - and that relates to ease of assembly, it is easier to put the lockwasher between the PC board and the standoff when the standoff is first attached - harder to fish the lockwasher between the board and the standoff on the 2nd end, but OTOH, the control board sits on top, and is the most likely to be removed in the future for firmware changes or other service, so the bast location for the lockwasher is between the L-C board and the standoff, then on the control board the lockwasher can go under the screw head. 73, Don W3FPR > -----Original Message----- > > I'm nearing the end of construction for my KAT2.
