[time-nuts] Thunderbolt vs Motorola M12+T

[Tijd Dingen]

Same here. A GPSDO like the thunderbolt is really nice from a system 
integration point of view. Buy an easy thingy kit on ebay, and you have
your 10 MHz reference. However, cannot a lot be gained from using a
more up-to-date design with newer gps engine?

On the one hand we have a thunderbolt which you can view as blackbox
that has a nice stable 10 MHz as output. On the other hand we have for   
example a Motorola M12+T where you have to do your own oscillator 
disciplining. At this point I am more inclined to go for the thunderbolt
since it solves a lot of problems. However I feel that with a modern
gps engine with better pps signal + a good quality XO you could get
a better 10 MHz signal. Any thought/experience/tips?

thanks,
Fred

I also would like to know the answer to that question if you use the 1 PPS  
of the Tbolt  versus the M12 or maybe a later model affordable GPS engine.

The t-bolt is a GPS disciplined  oscillator.  the M12 is only a GPS and
you'd need to add the  oscillator and the means to discipline  it.
