I wonder if I will be designing crystal controlled 60hz AC signals to bodge
into my clocks sometime soon. :(

Sounds like that's going to screw with my nixieneon clocks;-(

This does suck in a lot of ways.
I like how they say it will be a lot harder to control not with things like
wind and solar. I don't see why, I suspect most of these will end up going to
or starting out as DC then being converted to 60HZ. If they could do this with
massive turbines and physica
Glad I live off the grid and don't use the mains for timing my clocks. I
won't notice a thing...

Personally, I do not understand what the benefit is of using the mains
frequency. I always use a 4.194304MHz Quarz and so far all my clocks'
accuracies are very satisfactory.

The mains "frequency", at least here in the U.S. is always being
corrected for small variances that occur in the frequency during the
day. Therefore the overall error is none over a years time. Clocks are
therefore always accurate and never need resetting, unless of course
there is a power fa

I agree. I wonder what is REALLY behind this?? Something smells
rotten with this.!!!Ira.

Hello John,
YES!! I did read it , and for the life of me I can NOT figure out
what the REAL TRUTH is behind doing this. My comment was meant to be
past tense. Thanks, Ira.

The benefit WAS that the Hydro Utilities always averaged out the

My mother in law handed me an article today about this from their local paper

clock that reads the GPS and then sends it to the other clocks via RF. What
about a central clock that sends out a 60/50 hZ beat via RF? RF receivers
are fairly cheap, and then you only have to calibrate one xtal or wha
Are the RF receivers cheaper than the GPS receivers at this point?
Sparkfun sells some pretty small GPS receivers for about $25.. Course,
if you're into WWVB, digikey has a WWVB receiver & antenna for $10..

antenna with a larger
This clock

has two timekeepers - one from the Rb oscillator and one from mains

Very good price, but that isn't a GPS/WWVB.
I guess you could attach that to another and connect to a WWVB/GPS for
remote location of the receivers instead of a long antenna wire.
Maybe have it connected to your garage door so the clock can open/close the
door depending on the time of day.
Still, that's a pretty neat piece of kit. I might have to find an excuse
to put one in my next project.

Make sure to buy the 315mhz version instead of the 433mhz.. 433mhz is
smack in the middle of the 70cm band and is used for linking repeaters.
Also, unless you're a licensed amateur, transmitting on 433mhz is
