National Periodic Test of the Emergency Alert System - BEHIND THE SCENES
Вставка
- Опубліковано 14 тра 2019
- This is the behind the scenes look of what happens at a radio station when a National Emergency Alert System (EAS) message comes in. This was only a test, but if this were a real event, we would be hearing from the President or his designee.
This test originates from the FEMA Operations Center deep underground via the Integrated Public Alert and Warning System. This distributes the audio file to the boxes so that the audio quality is as good as at the source.

Lovely setup! :D
Nice!
That sound scares the living hell out of. MY brother
Who's here on October 4th?
Nice
This is beautiful. This confirmed the "Can IPAWSOPEN CAP do live audio" question.
Unfortunately, no. That wasn't live audio. It was a file that was fetched. Live would be phone quality as it would have been from the FOC/FAOC and would patch in WHCA. I have a recording of that process when they did the limited EAN test in Alaska several years ago.
@@TheBroadcastEngineer That is really great! My friend has a DASRADR unit, and we were wondering how CAP would handle a Live EAN, because according to part 11, it has to be live. We had only seen File parsing as of now.
Live happened just not with CAP a few years back. Came through the PEPs.
@@TheBroadcastEngineer Understood, Still, Amazing video! The SAGE Digital ENDEC is one of my dream encoders as an EAS hobbyist and Ham Radio operator, I already have the last model, SAGE EAS ENDEC as my daily driver for my EAS oriented IP station I run.
This is sick I never new
1:04 Here we go.
assuming this is in the USA, are the eas alerts quite often? (as in, one or two a month) or are they extremely rare? eas alarms are super interesting to me because in england we dont really have them in the same way, usually it’s just someone interrupting a program to make a statement without any tones.
You have assumed correctly.
There’s weekly tests that are just the tones (without the attention tone) and monthly tests (just like a real alert). Actual alerts for non-weather events at fairly rare, with weather events being extremely frequent during certain times of the year.
It all depends on where you are. I live in a state where I can go whole months, or almost an entire year without an EAS alert, only typically be issued by the NWS for a weather alert. Meanwhile I'll go to Florida on a small vacation and without fail. I will get at least one alert from the state. One time I was in Georgia about 20 miles from the Florida border and got an alert for a kidnapping in south Florida, an 6 hour drive from my current location.
We have two types of test. One where the full thing is tested once a year, one where the local portion is tested once a month with the tones and data stream, and one done weekly where just the data stream is tested.

sage digital endec. nice
i wonder what is so special about the attention tone in the start
The one that I remark "what's that" or the squawky ones? If it's the squawky ones those have data in them. They use audio to send data (called Audio Frequency Shift Keying, AFSK) that tells about what the EAS message is. It contains event code, location, and who is sending it.
@@TheBroadcastEngineer Oh cool no wonder why it has a unique sound
Hey there. I am blind and I have a EAS TFT 911 unit. What unit is this that you were using? Is it Wi-Fi capable?
This is the Sage Digital Endec. It is not wifi capable. There are no wifi capable units on the market at this time.
@@TheBroadcastEngineer oh ok. I was looking for one that you could hook to the Internet.
All of them are required to be able to connect to the internet but with a cable instead of wifi.
@@TheBroadcastEngineer do you use ethernet cable or watt?
Yep! Ethernet cable.
Never knew*
Noice
Who was talking was it already recorded?
The EAS is essentially a relay system. So we broadcast it over the air and another set of stations in the are pick it up and rebroadcast it.

i wonder what the dings (4 of them were heard throughout the timemarks of 0:05, 1:21, 1:47, and 1:54) represent
Those were emails coming in on my phone. Our EAS box sends me emails.
