I have a spare model 220, 8 pole 2.4 KHz SSB filter for the 9
MHz IF, it will augment your Corsair I or Argosy. It can also
be wired in for the older Argonauts to produce better SSB
receive. I would like $55 shipped conus.
I also still have a working model 217 filter, 500 Hz CW filter
for the 9 MHz IF. It has some ripple and is a bit lossier
than a newer one I had, but works OK. Probably a crystal
or a cap in there that is not quite up to par. I would like
$25 for this filter.
