[TenTec] Jupiter and KENWOOD SM-220 STATION

[Duane Grotophorst]

The IF's of the Jupiter are 45Mhz, 455Khz, and 12Khz
(maybe 14Khz). While it may be possible to adapt the
SM-220 to one of those IF's the gotcha is that the 1st
LO tunes in 2.5Khz steps. So the pan display on the
SM-220 would be jumping back and forth that same 2.5
Khz as you tune the radio. So probably not practical
to interface in the long run.
