Does anyone know the status ?
Google turned up this PDF

Which states:
"NIST ended its Geostationary Operational
Environmental Satellites (GOES) time
code service at 0 hours, 0 minutes
Coordinated Universal Time (UTC) on
January 1, 2005.
Hi Stanley:
No longer operational. Also non operational is Omega.
LORAN-C on the other hand is undergoing modernization.
Have Fun,

It didn't quite quit on that exact date but, yes, GOES is no
longer transmittng a time code. The existing legacy users
switched over to GPS the past ten years.
That paper is also available as document #2013:
The GOES Time Code Service, 1974 - 2004: A Retrospective
As far as I know, that's exactly what happened. It was, in fact, the
primary reason that I got rid of my GOES clock, bit the bullet, and invested in
some GPS clocks.
I admit I was somewhat annoyed. It can't have taken much overhead to
provide timecode through the GOES data strea

I'm not sure, but I suspect it was considered a both non
I've found that once the units gets into an overshoot/oscillation cycle
it never recovers and I have to manually adjust the dac to break the cycle.
Is the notion that you use conservative enough settings so that this
never happens?

Hello Scott,
this means the gain is set too high so that there is not enough phase margin.
You can try to set the serv:dacgain lower, and serv:efcs / serv:phaseco
lower.
Contrary to OCXO's, Rb's are quite stable so they don't need strong control,
they just need a gentle nudge, so you can
Hello Scott,
forgot to mention: also try setting the serv:efcdamping lower. It's an IIR
low pass filter, and will introduce phase-shift that can cause instability if
it is set too high.
bye,
