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

One other question, please. Will it be possible to just send in the KBPF3
from my K3 to be modified by Elecraft? not the whole K3?
Yes.

So, just to be sure I have this right:
If I have the NEW KSYN3A synth in an old K3, and if I still have the OLD
KXV3A, then replacing the KBPF3A with the NEW KBPF3B will give me all of
the enhanced performance available on 100 - 500 Khz?
I am thinking of replacing the KBPF3 rather than doing the
There is also a change on the RF Board that has to be made (or the KRX3 -
depending on where your KBPF3 is installed), in addition to the KBPF3 update or
replacement.

Ted,
The discrepancies in instructions are due to the KPBF3A instructions
being written with the K3S in mind, while the KBPF3 mod instructions
were written with K3 in mind.
If a KBPF3A, or a modified KBPF3, is installed into a K3, the RF board
(or KRX3 main board) bypasses must be done for
A further question about this . . . Having just read the installation
instructions for both the KBPF3A and for the mod kit for the old KBPF3, I
note one difference. The mod kit requires SM work on both the existing
KBPF board and soldering on the RF board itself. The new KBPF3A
instructions
The K3 RF board will still need the new capacitor even if you're installing a
KPBF3A (which has the LF mods already).
This will be made clear in an upcoming errata for the KBPF3A manual.

The manual for the mod suggests it's not all that
hard to do, Ed; I plan to and I don't work with
SMT without due consideration.
In any case, you can send only the boards needing
the mod to Elecraft, not the entire K3, according
to an earlier post by Wayne

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
