I admire your tenacity on this project, Ken!
It's far beyond my capability or inclination.
I expect that your stability problems would be
even worse running the L.O. frequency above the
signal frequency!
If I am EVER inclined to use a "command set"
receiver again for upper bands, I will revisit
what I did back around 1956 or so and use the
1.5-3.0 receiver as an I.F. for a Morrow 5BR-1
(or -2) mobile converter. One of the BCB units
would provide better selectivity, but I heard it
is rare to find one of those with an intact BFO.
This is what I did for a main receiver for about
two years then.
