Couldn't wait till morning on this as it was on my mind this evening. I
unplugged the Thunderbolt from the wall and plugged it back in. Immediately
the frequency counter attached went from 9.. to zero then when it was
powered back up went to the other side of 10 MHz at 10.000 and

Thank you Didier.
I'll check tomorrow for further issues.

Yes of course. When that happens, the Thunderbolt is said to be in holdover.

Hi,
I just noticed the laptop that is always connected to my Thunderbolt had a
yellow block under COM1 on the Tboltmon program where it normally is green.
Also the date up on the screen was in early July. Satellites were still shown.
The counter I leave connected still shows a 10 Mhz output.

Hi John appreciate the problems at HF, and Boulder is very close to the
track of the totality to use WWVB Enjoy the event hope you record some
interesting effects.

If LH can adjust the system time (I don't know if it can) then you could
in addition install ntpd and configure the "local clock" 127.127.
That experiment is happening, too. Folks will be monitoring WWV and CHU
in narrowband mode with the same tools they use in the frequency
measuring tests. (You can't really do direct phase comparisons on HF
frequencies because between the noise and the ionospheric effects,
including doppler sh
A Time Nut would measure phase change across the path of totality using GPS
locked SDR receivers :-)) As was done on the Eclipse that passed between the
UK and Iceland a couple of years ago. Keflavik NRK's ionospheric signal was
returned from inside the path of totality to most of the north of t
Could Lady Heather provide an NTP server so a local NTP client could access
the GPS time ? Or is that an overcomplicated way to do it?

I use an NTP client to set my Windows 7 64 bit PC time for digital
mode amateur radio activities, but I was wondering if my Trimble
Thunderbolt and Lady Heather can do the same job? If it can, how do I
do it please, and can the PC show GMT and not UTC, and finally does
the date glitch affect this?

This idea keeps coming up. "Jamming" the time from a GPS into a
computer is NEVER the best idea. When you "jam" the time the PC
internal clock moves in jerks and jumps where it will move forward
and even backward.
The only way that works well is to discipline the PC's clock using the
same meth
