I don't think there are any mars frequencies that fall inside the amateur
frequencies.
What happens when you try to tune up the SB-220 on one of the mars frequencies?
I would think you can easily tune the SB-220 to say 3.501Mhz, using the
"factory" tune up settings and procedure into a dummy load. Once it is in
tune, start moving down in frequency a little at a teme, retuning the amp as
you go. You'll have to "play" with the dial settings because they are not
going to match the normal values.

oh yes! in fact virtually 100% of the freqs are outside the ham bands
and probably 50% are outside the capes of the 220 which are set for
the ham bands.

so far, it is a LOT of work unless you are into home brewing<G>.
best toe in the water paper is RMeasures' 1989 QST piece which you can
find at http://www.somis.org/add-160m.html
