Ross and all:
OK, my error. I thought the caps on the main board were sm 0403
caps. By replacing the KBPF3 with the A version would avoid sm work,
or if you do not presently have the KBPF3 then the new KPBF3A will
have the necessary changes incorporated. That should make upgrading
the K3 easier for many folks who are unfamiliar with sm work.
Trying to do sm for the first time would not be advisable with 0403
sized components. Start out with 1206 or 0805.

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.
