[ntp:questions] Atomic Signal Transmitter/Repeater???

I'm actually working(slowly) on something like this.  A good sixe
antennal will go up inside a 20 foot tall pole in the back fence.
This will receive the 60KHz signal from WWWV Ft. Collins, Co.  There
are several antenna types but I've found a 4" loopstick works here.
Them the signal is converted to a binary time code and put on a RS442
serial cable.   rs442 is good for at least 1,000 feet.

But if all you want is an accurate clock, any cell phone is pretty
good, iPhones and iPads stay on-time most people now have one of there
with them full time.  You see very few peole with wrist watches
anymore and no one under 30.

My purpose for getting WWWV is to compare it with GPS time and I hope
maybe learn something about the atmosphere.  Any different in the two
times must be because of the path delay.
