[time-nuts] Lost GPS lock or 1PPS recently?

[Scott McGrath]

Actually 

I do have much of my equipment inside a shield room,  not for tinfoil hat reasons but to keep experimental systems from causing interference and to eliminate existing RF sources in the 800 Mhz to 8 Ghz range as error sources in measurements.

If one is concerned there are lots of old screen rooms coming up for sale on e-bay as WiFi manufacturers prepare to dip their toes into bands above 10 Ghz and many of the old ones were only good to 6-8 Ghz.  

As to backup generators I have a modern one and an ‘old school’ mechanically governed one with magneto ignition.    I keep that one mainly because i like its Art Deco design.    Sometimes bring it to local Ag Fair to display among the gear from that era.

Gentlemen, I've found this discussion interesting and informative. This
household works on quantum information theory rather than engineering so
there is much for us to learn.

I must observe that if an event takes out the entire GPS system (which a
Carrington event would not do) we will have issues a great deal more
immediate and pressing than getting hyper-precise timing systems restored.

And speaking of Carrington events, how many of us have our equipment
surrounded by Faraday cages and supplied with off-grid power? Because
without those, we won't have instruments to measure T&F at home or even in
a great many labs and businesses.

Just a thought.....
