I have often wondered why somebody hasn't designed a very good solid
state/transistor SSB/CW board(s) for the 455kc and 500kc ifs. Could sell the
board with or without components. It would have buffer amps &crystal carrier
oscillators for SSB & CW and maybe 2-3 positions for the Collins torsion
type filters (Rockwell Collins sells them for around $100 each in qty 1 and
they have bws of 2.5 and 5kc plus bws available.  I have these 2 for one of
my RA6790s) and a audio amp, maybe one of the 5w chip amps.  Board could
have jumpers if the filters were not used.  Maybe a MC1496 or equivalent
product detector.  Designer could sell the boards. lots of radios could use
them.

Guess I will dream some more......

Hi,
I have recently added an R-392 to keep the R-390 and R-390A company.
Looking for suggestions for a small, DC powered SSB adapter that I can use
with the 455 IF out?
