No.  On the main RF board (and the sub RX board if necessary) it's 
merely adding a through-hole cap.  If you have the KBPF3 (no A) then you 
need to do the SM work.  As Wayne stated earlier in the thread, you will 
be able to send your KBPF3(s) to Elecraft and have them do the work.  
AFAIK there is no KBPF3B ;)  If you've got/buy KBPF3A(s) then the mod is 
already done to them.

If I'm not mistaken, Mouser part # 647-RL81C221MDN1KX should be 
appropriate for use on the main RF board/sub RX.
