[time-nuts] Eureka, no more Cs, active or passive H-masers or GPSDOs needed

[SAIDJACK at aol.com]

We've sold a bunch of GPSDO's into that market, and with the towers  
generally being placed on mountain tops lightning protection becomes a real  
challenge..
 
Maybe their GPS receivers are burning up all the time, and that's why they  
need some sort of none GNSS reference?!
 
bye,

Rb  sources are considered too expensive here in Italy for the TV
broadcast  market. The patent was issued by a small company that
produces digital TV  transmitters able to exploit the single frequency
network specifications of  the ETSI standard and so a stable and
accurate time and frequency source is  needed: usually a GPSDO with an
OCXO at its heart. Very rarely do we see a  disciplined Rb.
