David,
I forgot to thank you for your helpful site and NTP plotter.
I have the antenna outside with a 180 degree view of the sky, outages
should be rare. Looking at the loopstats, the outage during the 4 us
jump is about 12 seconds. This is a test server, I only have the LOCAL
and PPS refclocks configured so during the outage the clock just
flywheels. I agree these cheap GPS receivers are more than enough for a
stratum 1 NTP server.
How about a 10 channel TIC? I'm sure someone could suggest a way to do
it, probably several PICTIC II's?
============================================
Agreed, that if your antenna has a good view of the sky you should not be
seeing these drop-outs, at least not on a regular basis. There are
atmospheric conditions which will affect the GPS signals, though, but they
should be rare. No chance you get a trucker with a GPS jammer driving by at
the problem times, I suppose?
You say LOCAL and PPS - no "seconds" reference such as GPS/NMEA?
You might also want to check what's happening on the box at the time of the
jump. If it's regular, perhaps some scheduled task is the cause?
Cheers,
David
