[SBE] EAS CAP

[Edwin Bukont]

I have said for quite some time that what should happen is ubiquitous distribution of emergency info by FM digital SCA. This could originiate at transmitter sites, including aux sites, not studios. This could work even with HD radio.  Every primary station, probably more than one per market, would have direct links to authorities.  That primary station could then decide if the info is to be rebroadcast on their main program channel.  Stations downstream would monitor the SCA, and rebroadcast it as an SCA, as well as again decide if the content was to be used in the main channel.

 

This would solve NOAA/NWS problem of penetration into rural areas not served by their own transmitters.

 

What we have now, this daisy chain in the main program channel, exists solely to appease a select few legacy broadcasters.
