Having said that, my Galaxy 5 worked pretty well with a 9MHz IF and

Apples and oranges since the Galaxy made no attempt to cover BCB range
ad certainly had no BCB parallel.

3200 kc Infradyne comes to mind as a "high IF scheme" for BCB but I
can't think of any older single conversion rig that used a high IF freq
for BCB? Ok, theres some 1600-17oo kc schemes. The older mindset was to
go lower in freq for improved Q.
