Betreff: [time-nuts] Ublox GPS board
I recently bought 4 older UBLOX GPS boards on eBay for $15
with free shipping. I hooked one up to my 1992 and comparing
it with the Z3801, I am seeing it jump all over the place. I
am using the 10 MHz output from the 3801
I tried substituting the 1 PPS output from the Z3801 and comparing it
to its own 10 MHz output and find the same jumpy behavior as I get
with the UBLOX boards. Well, not exactly the same but pretty much. Now
I am confused. I expected the 1 PPS to be in lock step with the 10
MHz.
Don't be burting my trust bubble here.
I would have thought they would be the same.
Now you are making me think.

Has anyone
here ever made any measurements on the UBLOX TIM-LF-0-000?
I think you hit an archeology site :-)
The TIM* modules were the first u-blox GPS receiver, introduced
somewhen around 2002/2003 IIRC.
I don't think
