Does anybody out there have a Trimble NTPX GPSDO? If so, I'd like someone to
try it with the latest Lady Heather version that is compatible with the Nortel
GPSDO units. I can send you the .EXE file

Hi
You are going to get a 5x10^-10 to 2x10^-9 per G frequency shift on most of
these oscillator. For anything below 5x10^-10 a pretty exotic crystal would be
needed...

Hi gang
Just to upset the apple cart a bit, high trees do not necessarily
protect a large area from lightning.
In my past life as a range officer at a large shooting facility, we were
hit by lightning directly in front of the firing line during a storm.
The tree line was about 20 to 30 ft behin

Hi all,
I recently connected up a USB GPS to my Linux box and found it quite easy to
get NTP to up from the GPS. I was hoping to get the same GPS to update the Mac
running Lion 10.7.4, however, it has been a very frustrating uphill battle.
Has anybody managed to get GPS NTP update working on OS
I had not seen this. Thanks
Often thought about building a clock like that.

This may have been discussed previously and I just missed it.
In any case, I just stumbled across this interesting project and thought others
on the list might find this time clock radio beacon driven by a pendulum to be
of interest:

Hello, it is usual now since there is a leap second scheduled for next

Is the GPS unit built-in (TBolt-like) or is it a separate module? Maybe
there is a firmware update for the GPS unit itself to fix the rollover
problem.
