If you want to turn the SM-220 into a panadapter/spectrum analyzer and
have lots more flexibility, you might want to check out the kits here:

As Alan pointed out, BS-5's and 8's are still floating around, but your
stuck with one I.F. same as the SM-230. The SM-230 is nothing more than
an updated SM-220. SM-220's came out in the late 70's.
