Hi Bob,
I think using a latching relay is a very good idea and prudent. Besides
while it is reacquiring lock you would probably be busy resetting VCR's
and so forth.

Hi Pete,
I don't have any way of knowing. I've asked the seller if he has a copy of the control software, and I don't like to go back with a bunch of petty questions like that. The next issue is adapting some serial port software i wrote to the protocol in the manual Magnus sent to see if I can pull the status codes out. That would probably tell me something.
I have some tests I want to run immediately on my GPSDO and the KS to settle
the question of which one can't keep time. After that, I'll power it down,
lift its skirts and take some pics. It's pretty simple on the surface: a Cs
Beam Tube, a main board, a microwave package with MTI 5Mhz OCXO, and the HV and
LV power supplies.
I don't intend to keep this thing running 24/7, but I have a question: Here
in Houston, we have the occasional large thunderstorm and resulting short power
outages. So, should I put a latching relay in the power stream to keep it off
if I lose power? The budget is now officially busted, and a UPS is not going
to happen for awhile. Santa's sleigh is now officially out of gas.

Love to have known how long it was off, and how much of that 16
minutes was getting the tube degassed.

Well, it's alive, and I even have 10MHz coming from it. It took about 16
minutes to go to lock. Is that good, or doesn't matter? Now I've got to put
together a serial cable and see if I can talk to it and find out how it thinks
it's doing. But, this is good!
