[time-nuts] Heathkit GC-1000 WWVDO

[Brooke Clarke]

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 heater.
On the other hand installing a switching power supply like the PT5101 will cool the enclosure but may degrade the 
stability of the oscillator.

Are there any WWVB disciplined oscillators (WWVBDO)?
