I would re-think this loose as a goose attitude about fooling with official emergency communications networks intended for licensed stations. The FCC takes the EAS/CAP extremely seriously. You dont just go slapping stuff and code together just to get the jollies of sending out the buzz saw data noise and tones to feel “big” like the big boys.
Now lets consider something else..to which a member did raise yet seems to have been ignored.
EAS/CAP is, and was designed and implemented into the broadcast radio service for alerting the public to both local and national emergencies. These stations are assigned designations and listed in each state’s EAS Plan. There are primary and secondary stations PLUS the NOAA station monitoring. Each are set up with a specific identifier within that data burst that is also specific for each station. The system allows for triggering a chain of stations in specific patterns per given situation, or all of them, or just one at any given time.
The EAS/CAP system is also highly regulated in which requires assigned chief operators/loggers. This means you will want to do exactly what the big boys do, and that is to monitor, track and log these events that come down the pipe. Oh…..the EAS data that is sent down the pipe is specific and triggers EAS boxes specific to area/scenario/purpose/station……that means YOUR home brew EAS box, which does NOT have an assigned EAS data code on the line, wont get triggered AT ALL for a specific warning for a specific area (yours)…..unless you bootleg those identifiers that is assigned for their LICENSED station.
I think the intent is admirable to help spread emergency information when emergencies arise. However folks…lets get real here and practical. Your talking about flea powered signal that barely reaches 1 mile on a perfect condition situation while the flamethrowers are reaching miles and miles. Your wanting to participate in official emergency communications set up and intended for licensed radio service to which Part 15 is NOT a part of…..and begging for regulation into this “hobby” than you are going to want around.
The best way to participate in spreading emergency information is to do what some are doing now…using wx radios and simply listening or monitoring them for warnings. All consumer wx radios come with an alert feature, which does not require nuclear science degrees or Ph.D’s to figure out how to interlink that into a switch matrix which can in effect give the same function as a real EAS system by interrupting programming to air the emergency information.
And that would be connected just like how the REAL EAS boxes are…at the tail end of the audio chain before it hits the TX and not through the mixing console. The way some of you are running your so called home brew EAS mock-ups…if they were actual setups called for by the FCC…you would be facing NAL’s left and right!
You cant just pick and choose what emergency information to transmit if your intention is to send out crucial emergency information specific to your location ya know. This is why the EAS system is set up like it is…so that specific emergency information for specific areas/stations are properly aired at their proper designated EAS points! (duh).
How about focusing on the “hobby” and not try to put on bigger pants that wont fit. More service from the Part 15’ers can be uniquely provided with a little bit of creativity and imagination.
