That would be R1058 and R1060 on the PBT/Reference board. These
resistors are a part of an attenuator for the BFO injection signal to
the MC1496 mixer.
Many thanks to Garey and Bill: Let me see if I can track those resistors
down and I'll post the results. I wondered if it might be something like that
as
all in all either version board seems to work.

I have noticed that typically the S meter on the version one boards are
Scotch compared to the version 2 boards. There are several changes to the S
meter circuit, and if memory serves me right, the AGC circuit also, on the
version 2. I have tried to update the earlier board with the new
I have S/N 6951 and it has a version 1 IF board. I have tried 2 different
version 2 boards ( which I know are in good working order) and they work but I
cannot get the s-meter to adjust: with the version one board my radio reads
S9 at 28 MHz but both version 2 boards read S8 or a little
4 matches
