Has anyone built (for "fun") a decoder that sits on a local station and
"lights up" when the EBS goes off? I mean, EBS is pretty pointless if
you don't have your TV or radio on.

Todd -- To answer your question -- first, a bit of understanding about the Emergency Broadcast System (EBS). In spite of the "attention signal", EBS is not meant to ALERT the public for "Civil Defense" purposes. They lost the political battle about twenty years ago to NOAA, the folks who run the Weather Radio on 162.40 / 162.475 / 162.55 MHz. Of course, NOAA never put the warning system into operation, but that's a different kettle of radios. The function of EBS is to provide "official word" about natural and man- made disasters (such as tidal waves, hurricanes, or explosions) from the "appropriate" governmental emergency services organization. It is NOT meant to alert the public that a nuclear war has been started. The Attention Signal is meant to unmute monitor receivers which are required to be located in every AM, FM and TV station, tuned to the Common Program and Control Station (CPCS), one in each county, which is required to have direct wire and radio links to the emergency services organization. In large cities it is not unusual to have more than one CPCS. It is the "text" of the CPCS programming which is meant to alert the public. So, in every station, AM, FM or TV, yes, there is (as your message described it) a decoder that sits on a local station and "lights up" when the EBS goes off. No big deal, my friend.
