[Kenwood] TS930 8.83Mhz mixer for SM-220 scope

[Terry Clinard]

Although this radio is 30 years old, it is still a great performer.  Does anyone have a schematic or contact to build or buy a simple mixer that outputs 8.83Mhz IF signal to use with the Kenwood SM-220 monitor scope?  The mixer takes the resident TS930 44.93Mhz IF and 36.10Mhz IF and mixes it to produce an output of 8.83Mhz.  Thnalk you  Terry Clinard  WA8OPR
