[time-nuts] Another "atomic" clock question

Hanging bridge? What is it; where is it found; and how does it form?

My guess is that a Google or Wikipedia search is going to come up with
something named Golden Gate or maybe a musical term.

I suggested yesterday to periodically heat and cool the oscillator, but my
post may have been lost in the noise.

>What would be more interesting would be to adjust the temperature of the
GPS receiver's oscillator to eliminate the hanging bridges altogether, kind
of like Trimble does with the Thunderbolt, except that they do it directly
instead of indirectly. That may require to characterize the crystal
oscillator to find out if it has an appropriate control range over
