[time-nuts] Alternate frequency sources - second opinions

[Hal Murray]

Hockey puck (or mouse) type GPS receivers are available for under $100.

What can I get in that price range that doesn't depend on GPS?  I'm 
interested in millisecond accuracy as well as nanosecond.

Has anybody built a WWVB-DO?  (Time to dust off my WWVB toys.)

Is there some good WWV setup?


Somebody mentioned TV and radio stations recently.  (I think it was part of 
the North discussion.)

What sort of frequency source is at the root of the local TV or radio 
stations?

Is the sync timing for TV stations derived from the same source as the 
carrier?  Or are there two separate clocks to discuss?  How about the 
color-burst frequency?

What do radio/TV stations do for backups?  If there was a hurricane or 
earthquake that broke the main transmitter are they likely to switch to a 
backup with a different timing source?
