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. :-)

This post is for K2 builders that have the internal KAT2 ATU. I am
completing a K2 build that will include the KAT2. The 2-pin connector (P6)
on the K2 RF Board connects to the RF input on the KAT2. There is a
clearance problem where inductor L20 overlaps the footprint of P6 on the RF
board. This overlap is about 2 mm in my case. The recommended solution to
this overlap is to simply unsolder L20 and roll it forward to eliminate
this overlap. I am uncomfortable with this and am thinking about using an
alternative method to make this connection. I'm interested in hearing from
other K2 builders who may have used an alternative to P6 because of this
interference issue.
