SPM12 IF freqs are 8 MHZ and 10 kHz.
Be aware the 25Hz b/w is an option and may not be fitted.
The PS12 is the matching level oscillator and the pair can be synchronously
tuned using appropriate interconnections.  Likewise the OD12 is a an
external afc/fine frequency controlling device that has  provision for a
number of preset freqs and allows 1 Hz step freq settings.
