Hi Nick:
The GC-1000 was the clock that not only received and was set by WWV (or WWVH) but also had a disciplined
oscillator(HFDO) at 3.6 MHz.

Tom: Have you made stability plots for the GC-1000 HFDO?
I recently got a Saunders Assoc. 150B Crystal Impedance Meter and the property sticker on the back says Heath Company.
I'm guessing they tested some or all of the 3.6 MHz crystals for the GC-1000 to be sure they would "pull" as needed.
I'd like to get my hands on a loose one of those to test it.

I just got an email announcing this:

They bill it as a "most reliable" clock. From the description it appears to be
an AC line disciplined clock with battery backup.
I only mention it here because of the periodic discussion of AC line discipline
and because I suspect I'm not the only one who remembers the old Heathkit
fondly.
