How the EAS alert was broadcast (it's just a test)

Ғылым және технология

DON'T PANIC! On October 4th, everyone in the US will get an alert.
Why? And how is it delivered?
We'll talk about the EAS (Emergency Alert System) for broadcast television and radio, and WEA (Wireless Emergency Alerts) for mobile devices. How they are propogated, and how and why the nationwide system is tested.

    The 2001 test was maybe not the worst ever. In 1971 by mistake someone sent out the "real, not a test" signal for the EBS by mistake. This accidentally showed why the tests are important: only about a third of radio stations actually switched to the emergency message. That wasn't the worst of it though. Imagine you're 80 miles away from WCCO's big high power AM transmitter in Saint Paul, MN, listening on a Saturday morning. Suddenly the music stops, and the announcer says, "This is an Emergency Action Notification." There is a real national emergency. Then, 40 seconds in to reading the alert message script, IT GOES SILENT. For ten seconds, as far as you can tell, Saint Paul has just been vaporized. Finally, some background noise and a voice: "They've run the incorrect tape. Disregard, disregard the last message." So yeah. Your dad's work, and doing it properly, matters.

    IMPORTANT PSA: If you have a "secret phone" (say you live in a "complicated home situation" and your main phone is monitored by someone you'd really like to escape from), MAKE SURE THAT OTHER PHONE IS POWERED COMPLETELY OFF DURING THE TEST. Like with the UK test a while back, _the notification and noise don't stop until you acknowledge them_ and it goes off even in Silent+DND mode! They do say that airplane modeing the phone will prevent it receiving, and it won't go off later (it's a one-way "at-everyone" broadcast from all cell towers, it doesn't "queue" it for the next time you're online), but it's best not to take that risk.

    I can provide insight as to why mobile phone alerts take longer. Outside of anything within the network taking time to process, there's an inherent reason within LTE to cause delay. So when broadcast, its broadcast on a loop by all cell sites within the area. This broadcast is a packet within LTE spec called SIB12. This packet will contain all the information about the alert, such as its level and what text to be shown. The network specifies to your device how often it should check for this SIB12 message within SIB1. Different mobile networks with different hardware vendors will have a different value. A higher value means your phone will check in less often, saving battery, causing the delay observed.

    This is a good insight into the EAS. I just wish Comcast fixed their EAS boxes as the weekly tests are actually 3 to 4 times a week; it like testing a fire alarm everyday as they do the full interruption and not the ten seconds as called for by the regulations. FYI: Illinois does their monthly tests on the first Tuesday of the month with the tornado sirens (skipped in areas with active thunderstorms that triggered a warning within the test time block).

    We get an additional test in our area due to the Nuclear Plant just down the coast from us. We live within the 10 mile zone around the plant so pretty much any major emergency there would affect us. They would be a part of the normal alert systems if they ever had an emergency, but their sirens are distinct from the tornado sirens that sound. They are tested at different times from the tornado sirens. I think we still receive a yearly calendar from them due to being in that 10 mile zone.

    Oh this is awesome! There's a whole world of information in those bursts of information in an EAS message, the SAME codes limit visibility (so an EAS message for Florida doesn't fire off EAS systems in Georgia for example), there is also the originator code (who transmitted this message), as well as what kind of message it is (Did you know that there's a tsunami and volcano mesage types?). We had a civil alert message a few weeks ago that ended up being for an island city that had to be disconnected from the utility power grid for emergency maintenance. The entire design of the EAS system is to be fully automated, this is why the ENDEC exists. It should automatically receive (DECode), store the audio message, and (reENcode) the message for retransmission without the operator lifting a finger. I have a much older ENDEC that I bought off eBay but being that I don't have a transmitter and I'm not a radio station, I use it for receiving EAS alerts from my PEPs using commodity radios (one AM, one FM, and one Weatherband). SAME codes set the "area" of the message being delivered, this prevents an EAS alert for Key West from triggering alerts in Tallahassee even though they're both in Florida, or preventing a statewide alert in Florida from triggering EAS repeaters in Georgia for example. Finally, the protocol itself is interesting, the reason why the start and end bursts are presented three times is because there's no checksumming in the protocol. It's broadcast three times and it's up to the ENDEC to keep the correct data. And your dad's right, the EOM message bursts at the end of the message is important as it tells the ENDEC to release the transmitter (back to the normal audio). An ENDEC that doesn't release the transmitter can hold a station offline (dead air)!

    @@fitybux4664 I agree with @user2C47, desktop radios are usually plugged in (utility power + battery backup) versus a battery only portable model. In a portable radio, only the tuner, a frequency filter, and a logic circuit would be needed to be powered. The alert tone causes the logic circuit to fire up and it turns on the amplifier and you hear the audio. To process the SAME headers, you'd still require the tuner, but the frequency filter and logic circuit would be replaced with either an ASIC, FPGA, or microcontroller for parsing the header, deciding if the message received is relevant, and then triggering the amplifier. Since desktop models aren't power constrained (they're not intended to be run on batteries for an extended period of time and usually are plugged into the wall), they can implement the SAME processing easily. A portable unit would be much less reliable as it'd have to keep the additional hardware powered up at a significant power cost. As far as recording the audio, all of the ENDECs used in a radio/television headend will record the audio to some storage media for the automatic rebroadcast. My TFT ENDEC has a bit of flash and I can review the last message recorded (older recordings are erased), but the SAGE ENDEC demonstrated here has a lot more storage and can store several messages (not sure how many, but I'm betting it's more than my TFT's one message). I'm not sure if SAGE uses flash for storage or a hard drive but if I had to guess, it's probably flash-based. If you're the tinkering type and have access to a USB SDR dongle, you can easily build an EAS receiver using software as the protocol is fairly simple to decode. I've found a few projects like this out there, but decided on doing this using a dedicated device rather than tie up my computer listening to the radio all day.

    Because the test times are announced ahead of times all stations have a shot to try and have it occur during a break or during programs. Since playing over a commercial would cause a loss of income I assume most will choose to interrupt programs. Some creative programmers have played songs with messages like ‘I will survive’!

I'm sure many were injured during that "not a drill". (Also, I should add that I am quoting a historic event, and there is no current missile danger to Hawaii, that I know of.)

    I would like to know more details about how the messages are distributed. Maybe I missed you saying it, but from what I could gather, seems like it's almost like a call tree where one station (or probably a group of stations) at the top of the tree get it directly from the government and transmit it out, then for each top level station, several other stations hear it, and transmits the message themselves and the relay continues propagating the message across the US. (?)

I have an extra radio for shortwave but i'm not sure if EAS broadcasts on stations like WWV, WWCR, or WRMI. If anyone knows let me know and i'll include it in my test. Personally I'm not a fan of the interruption the EAS causes but I know it's a very important tool and the results of this test would be a very interesting topic to discuss on my tech blog.

Lesson learned many years ago when we were under a tornado warning and we tuned to WGN and WRMN for updates, and they just kept right along with their normal programming not to even update people about the situation, as if those were more important than the very severe weather going through our area at the time.

    We have had this system for a few years now where I live and unfortunately my government and authorities are abusing or misusing it. They have used it to announce curfews, and they often send amber alerts in the middle of the night when it can be done hours sooner. It's as if they want to annoy us with it as much as possible. Because I have anxiety and those random alarms were not helping, I looked for ways to disable it on my phone. Disabling those alerts on my previous phone had no effect and they were still blasting and screaming even though unwanted and disabled. I ended up muting my phone and missing calls and notifications because I didn't want to risk that alarm sounding randomly every few weeks. Luckily I have a new phone that really does disable the alerts and I couldn't be happier.
