Also, since the 5,3 MHz is modulated, 1,4 kHz apart is the two signals,
and then a skirt of side-bands as the frequency modulation is relatively
It's not clean.
BTW. A fun hack would be to hook up the 63,8976 MHz OCXO in replacement
of the 60 MHz and then re-adjusting the DDS to 2.35645 MHz, as the 107s
overtone of the OCXO minus the new DDS frequency hits the Rb resonance.
