[time-nuts] Does a frequency counter locked to GPS need to "warm up"?

[Bob kb8tq]

Hi

It depends a *lot* on the frequency counter. An old style “just count the number of
edges” device should be good to go pretty fast. One of the “fry an egg on it” interpolating 
counters that get into the 20 ps range may well need some time to stabilize. If you 
are doing ADEV runs, a couple hours of warmup would be a good idea.
