One can "roll your own" 10 meter addition to the SB-221
The parts are generic less the front panel, of which an
very nice reproduction is sold by Martin Tippin.
-
I did one years ago (actually decades), I seem to
remember the SB-201 (little brother) being more of
a pain.
-
The input networks of the last SB-201 I did from
scratch parts required changes as the original values
worked with the anti CB Low pass filter in place.
-
Its not just the addition of the expanded band switch
capacity and one tuned input on the SB-201.
-
The most practical retrofit parts source would be
to buy the originals removed from one of the guys
placing them up on six meters. I used to buy
stuff from Carl, but he's long off the radar screen.
