[Elecraft] K2/100?

[Fred Jensen]

I run my K2 from a 4S1P LiFePO4 pack.  I ultimately sold my KPA100 and 
KAT100, I use the K2 QRP-ish in field activities and it is indeed a 
hassle.  A warning to anyone who does swap the tops:

There are two 2-wire Molex connectors from the KAT2 to the K2 RF board. 
  One feeds RF to the tuner, the other 12 VDC.  The cable lengths from 
the KAT2 are such that either cable will reach to either socket on the 
RF board.  The two connectors are identical.  If they are exchanged, the 
shield on the coax feeding RF to the KAT2 ends up on the 12 VDC pin. 
This should only be done if you decide to re-purpose a power trace on 
the board to become a fuse.
