[Elecraft] [K2] Issue with KAT2 connector

[Fred Jensen]

Well Dave, the "Elecraft-Correct Answer" is do it the way they 
recommend.  Because of the modularity, I'd guess that when they're 
servicing K2's, they might swap in a known-good module to troubleshoot a 
problem.  Changing the connector makes that hard[er].

That said, note that there are in fact two of those 2-pin Molex-type 
connectors on the RF board.  Note also that the each of the 2 cables 
will reach to either connector.  Swapping them will short the 12 V and 
blow your fuse[s] ... hopefully.  I don't recommend changing one of the 
connectors, but I do recommend some bright nail polish on one of them 
[both sides] to lower the probability of misconnection.

I'm sure you can deduce how I know this. :-)

73,
