[Premium-Rx] Time Signal Station Receivers sought

[Ed Tanton]

I don't know if they still do it, but local TV stations are (were?) 
sync'ed to network standards which are either rhubidium or 
cesium-based (I think the former-but don't really remember.) Hence, 
when a local station has a network show on, their frequency is pretty 
accurate... and so would you be. Thinking about it, I believe a 
simple MM5369 (after all, they did use color burst xtals) would have 
yielded some pretty accurate timing-or use an appropriate set of 
dividers for a similar result when combined with something like a 
4046 PLL to lock wit the TV station. Nothing hidden about it.

These days, a Rockwell model TU30-D140-221 GPS receiver capable of 
connection to something like an Isotemp OCXO134-10 disciplined 10 Mhz 
OCXO can achieve stabilities on the order of 1 PPB over a 5 day 
period... making that a much easier route to stabile frequency or 
time... all for less than $150-and a few parts (included with the 
<$150 on ebay) plus an antenna.
