I was responding to Joe's observation that you could use one of the
Spectracom units as a phase comparator if you replaced the internal
WWVB reference with an external reference. The unit as modified no
longer receives WWVB -- instead, you feed it 10 MHz from your GPSDO,
cesium clock, H-maser, whatever.
Best regards,
