Re: [time-nuts] Receiving the MSF time signal on cheap radio modules

MSF disciplined oscillator?! I don't trust these receivers to any better
than about the 20ms mark, so such a disciplined oscillator would have quite
a long integration time!

It would be interesting to see if you can find any pattern in your histogram
plots.  Say, time of day.

What happens if you average over 10 or 100 samples?

Challenge accepted.

This graph is probably not too useful, for the simple reason that when the
receiver is spitting out mostly noise, the averages are going to be
massively affected.
