Hi Bill,
where are you located? since something like that, would be a perfect
"therapy" for me, because I am always buying "all kind of junk" [my
wife's opinion, but it is very close to the reality ] and after I fixed
it and played with played with them don't know what to do with it...and
it
I just realized there is also a 100 Hz decoder also u402.
Both use the typical open air 1 turn pots. They get cranky with age.

Paul.

Hi: Bill
Mine needed pretty much all the electrolytic caps replaced.

I see the manual is online for the GC1000.
The 1KHZ tone decoder may be suspect in that its drifted off frequency. Its
a little ne-567 chip with a pot.

Hi, Bill.
I have three GC-1000s, one unbuilt and two built. Both of the built
radios have stopped showing a time display. I haven't had a chance to
figure out what happened to them. I live very close to Fort Collins, CO.
I experience power failures fairly often and when my clocks were working
I own a Heathkit GC 1000 Most Accurate Clock. It's in terrific shape but not
used for many years. It has stopped locking up to WWV and sometimes freezes
up. Can any of our "nuts" repair it? Anyone want to buy it?

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 OCXO
reference vs.
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.

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'll second that. I built mine when they first came out and it's still
going strong. Come to think
of it, pretty much all the Heathkits I build still work today.
Only thing I've done to it is replace the resistor - 5V regulator combo
with a drop in
switching regulator. See: http://www.amug.org
I don't really know how rare they are, but they're reliable.
I have mine that I built many many years ago (20+), and it's still
ticking. It's been on continuously for all that time.
There's one listed on EBay now, item 160302101690. It's already up to $150.
