It works anyway.
I put it on a IFR (spectrum analyzer) and it's damn spurious,
especially on one of the sidebands! I shut-it-up a bit with tuning,
and I guess it's down about -40dB of fundimental, but I think it could
be cleaner. *AM is clean (better than 50 dB down) but it was touchy to
get it clean. At least the 11.275MHz doubler circuit is very
spurious. *I just ordered schematics from Kens Electronics.

Hi Harry. I collect Hy-Gain V's! It was my radio of choice awhile
back and now try to pick them up when I see them at ridiculously low
prices. They are too bulky for many people's taste but they are solid
and they last. You seem to know more about radios themselves though.
I don't know for sure but I know you can find Hy-Gain V in both 23 and
40 channel varieties. Perhaps that is the difference between the A
and B models.
