Hi:
Has anyone done stability plots on the Heathkit GC-1000? Although it's a clock good to 0.1 seconds, it's also a WWV
disciplined oscillator (WWVDO).
The linear power supply makes use of a 7805 and so heats up the enclosure which is hard on the electrolytic caps but
also acts as a crystal

Does an NTP server using WWV as a reference clock count as a WWVDO?
If so then there are likely a few of them around.
I have a really nice RF front from an old WWV receiver that I want to
get working. Well it does work but I'm using a general coverage
reciever to convert the IF to audio, need to

In the late 70s I added WWVB to the micro that controlled
my RTTY autostart station. A circuit in an application manual
demodulated the WWVB signal and a software loop synced
to the on-the-second transitions and decoded the time information.

I have a couple of Spectracom 8164 WWVB DOs running. They bounce around by a
part or three in 10e10.
The 8164 uses an FLL that does 1000 second counts of the internal
