Open up he SM-220. The band-scope option is in a small metal box toward the rear of the scope. It will be marked either BS-8 or BS-5, for 8 MHz or 5 MHz respectively. It may be possible to retune the unit to the desired operating range, although it may be necessary to juggle some component sizes. A schematic can be obtained on line I think. Note: if it is a BS-5, the only difference between the units is the oscillator coil and a few components. Replacing the appropriate parts with those for the alternate frequency range will make the switch. Since these are "discrete" parts, the swap should be straightforward. The 8 MHz version may have enough tuning range to shift over the K3 IF without changing parts. As supplied, the BS-8 is set for use with an 8.83 MHz IF, if I remember correctly. The band-scope print is part of the main SM-220 manual. .
