Information on EAS - CAP - IPAWS - FEMA

The idea is to bring some clarity to the issues and answer your questions. Definitions and
a fair amount of historical info is below, including air checks from the National EAS Test
(Last update 4/11/19)

4/11/19 - An erroneous message from PRSS (Public Radio Satellite Service) indicated they were to run an EAN (ConDep messaging that their NOC was conducting "a special EAN test today at 11:15am ET"). It was not an EAN, but merely an RWT. Reports are they did this last year, too.

2/9/19 - An error in the EMNet system in Michigan is cited as the source of a false Winter Storm Warning this week. Apparently, and NWS line was mis-interpreted and passed to the EAS system via IPAWS. Other similar errors were reported from Alaska to the East Coast. The NWS is investigating.

1/22/19 - A reminder that BLU is now an optional code for EAS. Use is optional.

If you have a DASDEC, it is in Ver 4.0 of their software. Trilithic users have it in Ver 18.10. Sage with have an update next week. Gorman-Redlich users should check with the company.

12/21/18 - The FCC PSHSB has released its "initial" findings regarding the NPT in October.

Here is the link to the FCC ETRS site.

10/3/18 - The 2018 NPT happened on schedule yesterday.
The Good: Most stations got it and relayed it with good audio.
The Bad: Many stations did not get it because of failure to update the FEMA certificate.
The Ugly: The FCC servers were unable to handle those trying to file Form Two, wasting a lot of time, especially for contractors trying to help many rural stations.
On the plus side, most reports said the audio was cleaner than last year.

REALLY BAD: some stations using FEMA B-Roll, and the ABC Jimmy Kimmel Show, used EAS tones (Kimmel as many as four times) in news or - worse - comedy lines.
The WEA test was more spotty, with perhaps 25% or more failure, mostly due to older cell sites and resistance from some providers like AT&T.

The BDR Notes: The FCC's insistence on using their web site to report (ETRS) again wasted a lot of time for each broadcaster who tried to file.  Some were just delayed, but many contract engineers, asked in to small stations, found the delays and rejections time killers i- plus there was a need for them to know the "password" to each licensee - a real security issue. Will the FCC listen? They have not over the past years' NPTs.

10/1/18 - The FEMA has released a two-page information sheet on this week's NPT. You can grab a copy here.

9/28/18 - The FEMA had a major computer server glitch (Friday) causing intermittent connectivity to the stations - resulting in many error messages. By 6 PM Eastern time, activities had been switched to an alternate data center, according to information from the FEMA. According to the FEMA, "The EAS Atom Feed traffic was directed to the other data center. We anticipate running this way until Monday (today) when we hope to be able to get core connectivity issue resolved."

9/17/18 - The FCC has announced the NPT has been postponed to October 3rd at 2:20 PM EDT (right after the national WEA test at 2:18 PM), due to the disaster conditions in the Carolinas from Hurricane Florence. This is also a reprieve for those stations that have not yet installed the latest FEMA certificate to validate tests and alerts. It is a short upload, but needs to be done beginning September 24th.  Check with your box manufacturer's site for instructions.   DASDEC/One-Net   Trilithic and Gorman-Redlich do not need upgrades    Sage
9/13/18 - Another Certification update will be required for EAS Boxes prior to September 24th. 
If you are getting tired of this certificate mess, so are the manufacturers. At least one is in discussion with the FEMA to make these certificate updates automatic, and hope to have that in place sometime next year before the next expected update in November 2019.

8/16/18 - The FCC and the FEMA have announced the 2018 National Periodic Test (PS Docket 15-94) and the requirement that all stations fill out Form One on the FCC ETRS site - by August 27th. The NPT is planned for September 20, 2018 at 2:18PM EDT - From Two is due by midnight that same day. The EAS message will be disseminated via the Integrated Public Alert and Warning System (IPAWS). There is a Q&A on the FCC ETRS site that helps figure out the Form.

7/12/18 - At the monthly Open Meeting, the FCC adopted a number of items, with the amendments to the Part 11 (EAS) Rules as noted below (7/2/18). The R&O and NPRM is here. Perhaps of more concern is that Congress is now working on passing laws relating to EAS - in the wake of the false alerts earlier this year. We urgently need more people who do not understand EAS to make rules and laws. (not)

7/2/18 - This year has seen more than its share of false alerts: Hawaii's missile alert, Alaska's false tsunami alert, and Portland (OR)'s 911 outage that was not, among others. The FCC has issued notice for the July Open Meeting of the FNPRM discussion on the problem, and proposed actions, including:
    * allowing live code tests
    * allowing use of EAS tones for PSAs
    * would prevent false alarms by requiring CAP rejection for invalid signatures
    * seeks reporting of all false alerts to the FCC
    * seeks comments on SECC Plans to include ways to prevent falso alrms
    * seeks comments on why WEA alerts are delayed.

BDR asks: Now, what could go wrong here?

6/27/18 - Any station needs to be where it is licensed to be. When agents came looking for KVBB-LP in Big Bear Lake, CA, they discovered it was more than a mile from where it was supposed to be. Additionally, the station could not produce more than four months of EAS logs. An NOV was issued, and the station has to respond.

6/25/18 - Causing interference to other licensed stations is not permitted. Thus FCC agents discovered a transmitter on 461.700 MHz was not being monitored by its owner the Ontario Christian School Association. Agents discovered WQOK645 was putting out 5 seconds of digital signal every 30 seconds, interfering with co-channel users.  An NOV was issued.

4/11/18 - The FCC has released a Report and Order on EAS (here and here) - making a number of changes, especially in terms of the State Plans and a new FCC Web Site for reporting the Plans and updating them.

4/10/18 - The FCC Public Safety and Homeland Security Bureau's report on the Hawaiian False Alarm on January 18 from the Hawaiian Emergency Management Agency.

1/30/18 - The FCC has released its preliminary report on the Hawaii false alert. The story now seems to be the employee thought there was a missile coming. A news conference is scheduled for later today in HI. A report by James Wiley adds some more detail.

1/17/18 - North Dakota issued an LEW, but called it a Blue - nearly a year ahead of the planned phase-in. The Alert was issued but nothing was included explained what it was all about. Confused citizens who had not heard of Blue alerts were calling in. The suspect was found anyway, about 350 miles away.

1/13/18 - Hawaii Emergency Management issued a false alarm about a missile attack this morning, declaring it was not a drill (image here). So far, reports have confirmed it hit the EAS, WEA, and local sirens. Apparently it took over a half an hour to issue a retraction, after a Hawaiian Congresswoman (Tulsi Gabbard, D-HI) initiated calling the EM HQ. There are currently conflicting reports why a retraction was not issued immediately, nor exactly how it happened, but officials are conferring. 

Here is one analysis worth a read.

1/8/18 - The FEMA reports that the RWT for today did not happen for the Central Time Zone. FEMA engineers are "looking into the matter," to try to determine the problem.

12/14/17 - The FCC has approved adding the BLU code to the EAS. Stations will be voluntary users, manufacturers will be expected to include BLU in their next updates.

12/8/17 - The FCC has released its initial review of the 2017 NPT in September. The Public Notice is here.

12/6/17 - Alabama's EMA sent out an RWT with a CEM header by mistake. (Yes, a second time.)

11/21/17 - The IPAWS system server went off-line for about 11 hours between Monday night and Tuesday AM. It was re-booted and restored at 10AM EST. 

11/19/17 - Alabama's EMA sent out an RWT with a CEM header by mistake.

11/14/17 - The FEMA RWT of the IPAWS was delayed for several hours in the Eastern and Central time zones. Additionally, a mal-formed alert that should not have gone through the system was sent to some stations in the Central time zone.

11/9/17 - The FCC requires all stations to file Form Three by November 13th.

11/2/17 - The FCC mandated deadline for sending your multilingual plans is November 6th, based on the FCC's Compliance Guide in August. Check the top of page 3.  The SECC is to report to the FCC next year. Some SECCs have said they are willing to accept reports after the 6th. It is best to contact them to be sure!

10/13/17 - This is sort of an FYI: authorities in Sonoma CA last week did NOT use EAS or WEA for alerting people in the fire zone of Sonoma County (Santa Rosa) that has devastated that area and killed more than 40 people. They said it was an intentional decision. Observers noted the decision came after many cell sites were destroyed. This puts more pressure on stations to step up and serve, as did KZST Santa Rosa. Other reports note KSRO and its cluster were working hard, too.

9/27/17 - The NPT came and went. For those of you who had trouble doing Form Two, it has been extended. A summary is here.

9/20/17 - The FCC does remind you that you need a new 2017 EAS Handbook to be customized and printed. The download link is here.

9/20/17 - The FEMA has announced the 2017 NPT date: September 27th at 2:20 PM EDT, with a rain date of Oct 4th. Here is the official notice. The FCC's Public Notice is here.

Deadlines of note:
      1. All EAS Participants are required to register with ETRS and must complete the filing of Form One as soon as possible.
      2. The 2017 EAS Handbook must be customized, printed, and posted at the EAS Control Point.
      3. The "day of test" information sought by ETRS Form Two must be filed at or before 11:59 PM EDT on September 27, 2017.
      4. The detailed post-test data ETRS Form Three must be filed on or before November 13, 2017.

8/28/17 - Partially due to the effects of Hurricane Harvey on SE Texas (and likely partially due to the problems with the CORES and ETRS web sites), the FCC has extended the August 28th deadline for  filing Form One; later filings will be accepted - but stresses for stations to do it as soon as possible.

8/16/17 - The FCC released a "Small Entity Compliance Guide" repeated the requirement for SECCs to submit reports on how stations are handling multilingual EAS alerts. They are required to submit to the SECCs their plans by November 13th.

8/15/17 - An EAS test on the island of Guam went awry when a station employee practicing how to send an alert hit "send" instead of "cancel."

7/25/17 - The ETRS is now open and operative. Reminder: You must register and complete Form One prior to August 28th.  Trouble?  Contact Austin: 202-418-1462

7/11/17 - The FEMA has named 44 individuals to the latest IPAWS subcommittee, calling it one of its highest priorities for 2017. The subcommittee will first meet August 8/9 in Washington DC and is tasked with bringing recommendations forward to improve the public alerting system.

6/22/17- The FCC adopts the BLU alert for Law Enforcement

4/21/17 - The FEMA released its report on the 2016 EAS NPT in September. A copy can be seen here.  A test is expected to be announced during the NAB Show for this Fall, likely September.

3/24/17 - The FCC's latest order requires, among other things, for stations to submit plans for multilingual EAS operations to the SECCs for reporting to the FCC.  

12/28/16 - The PSHSB (Public Safety and Homeland Security Bureau) of the FCC has released its first look at the 2016 NPT in September. 94% of 21,000+ stations reported reception of the test, with 85% successfully relaying it. Over 2/3 reported no problems at all - all in all an improvement from 2011.

12/15/16 - The FCC abruptly called off the plan to vote on a number of EAS changes, including a multilingual requirement on stations. It appears that there will be no EAS action until after the inauguration of President Trump next month, and clarification of what he will do with the FCC's vacant chairs.

11/7/16 - A test by a US Cellular tech in the IPAWS test and development lab leaked onto the WEA system beginning around 1PM CST. The test went over the entire live US Cellular network and the WEA somehow was repeated as many as a dozen or dozen and a half times over a couple of hours. One report says US Cellular was involved (see screen shot). Apparently, any cell phone that "talked" to a US Cellular tower would have been affected.

9/28/16 -  The 2016 NPT went off pretty much as expected - a lot of success - it was a test, after all, and there is nothing wrong with failure, as it helps improve the EAS for future use as stations handle the few issues that were highlighted today.  More information is here. 

9/27/16 -  With a day to spare, the FCC has denied the request for wavier by Gorman-Redlich, so that older EAS boxes (which do not recognize 000000) might still be used. The FCC really wants the 000000 to be recognized. (On the other hand, footnote 51 does seem to indicate a possibility that individual stations may seek a wavier, but this might not have a certain result.)

9/19/16 -  Monroe-Electronics has released a short (6 page) illustrated application note for Version 3.0 users to help stations be sure they have got the necessary options set and ready for the NPT on September 28th. (Stations using Version 2.x should use this one.)

9/19/16 -  Today's RMT from the FEMA was only sent in three groups, much like the coming NPT next week. PDT, Alaska, and the Pacific islands were sent along with MDT (AST was with EDT).

9/14/16 -  Check your logs! The FEMA ran an RWT with 000000 at 2PM EDT today. This is a great opportunity to see how your receiver responds to an "All US" test. This is not a worry for anyone - it does not have to be logged officially. Rather, it is a chance to check your filters and see if your machine recognizes 000000, and what it does.  If you did not get this test, contact your manufacturer's support line - or the instructions you got on the last update. Unfortunately, there was also an invalid certificate issue - but the FEMA says this now has been fixed until 2019.

9/12/16 - Sources at the FEMA note problems with this morning's CAP test. It appears to have been centered on the certificate, which went out of date again. Some EAS receivers which have been set to  ignore a bad certificate have received the test. Others did not. The FEMA is working on the problem.

9/6/16 - In the aftermath of a botched EAS alert on Long Island, NY, the local County Executive first blamed the FEMA, then an EAS machine, then "the system" for an alert that included a truncated evacuation of Fire Island which could have been interpreted as ordering evacuating all of Suffolk County on the East end of Long Island.  

8/26/16 - This is when all stations are supposed to be registered for the 9/28 NPT. What happens if you do not get it done? The FCC says they are more interested right now in getting folks in the ETRS and getting their stations registered, so they can report on the NPT, than in issuing citations. So, according to the FCC, do it now, even if you are late.

7/11/16 -  The FCC added by Report and Order three new EAS codes on July 6th, effective on January 6th, mandating that manufacturers add them to their system and any upgrades made by stations after one year must include them. The new codes are: Extreme Wind Warning (EWW), Storm Surge Watch (SSA) and Storm Surge Warning (SSW). (As with "normal" codes, these are all voluntary.)

6/20/16 -  The Reply Comment period on the FCC's EAS NPRM is well along now, ending on July 8th. If you want to make a comment easily, just go to the EFCS to comment on Docket number 15-94. You can read the existing comments, or add yours.

3/30/16 -  The FCC has issued a Multilingual EAS Order. So far, the upshot is the FCC is telling to SECCs to provide data on multilingual EAS usage. It does not yet require multilingual broadcasts by EAS participants.

3/24/16 -  The EAS NPRM was published in the Federal Register this morning. Comments are due on or before May 9, 2016 and reply comments are due on or before June 7, 2016. One key point, the docket number has changed from 04-296 to 15-94. So be sure to use 15-94 on the ECFS.

3/3/16 - The FEMA announced through the Alabama Broadcasters' Association that an NPT will be sent to that state, in lieu of the cancelled one from last week. It is scheduled for March 10th at 11:15AM.

2/25/16 - How did things work out on the recent NPT? Like any test, one might call it a success, in that many stations got the test and either forwarded it or discovered some problems in settings - there were many reports on non-forwarding.

The biggest problem seems to have come from the FEMA and state broadcast associations in the South that cancelled the test at the last minute - but did not see fit to notify stations in any way.

Other issues included some AES settings caused the audio to be slowed dramatically - or no audio at all.

2/23/16 - The FEMA announced the next National EAS Test - it  will be conducted on Wednesday. September 28 at 2:20PM ET. It appears to be an IPAWS-only - not using the PEP stations via legacy EAS. Meanwhile, the FCC expects the ETRS (Electronic Test Reporting System) to be up and running by mid-year so EAS Participants can "sign up" before the test.

11/23/15 - The FCC advisory committee, CSRIC will meet on December 3rd to discuss ways to improve the reliability and security of the communications infrastructure. The meeting will be streamed at

11/19/15 - The FEMA NPT went off well according to reports. Reports from the various states indicate that most stations got the NPT.

In fact, even a non-advertised function went well. Users of the DASDEC EAS receivers reported the ability to get Spanish language versions of the test cleanly and clearly. This demonstrates that it is possible to send language specific alerts to areas of high concentration of various language speakers.

We asked Ed Czarnecki, Monroe Electronics’ senior director for strategy and global government affairs, about the multilingual aspect of the test. He said "The NPT was a single CAP message with two information blocks - one in English and the other in Spanish. Each info block contained the full expanded text of the Emergency Alert in each respective language. The CAP message also contained two audio files embedded in the message itself - again English and Spanish.

DASDEC multilingual users have the option to configure their systems to play either language or both. 

If the audio file was damaged or unplayable for whatever reason then the DASDEC would utilize fully featured text to speech. However all the multilingual - DASDECs played the original audio file perfectly.

The successful completion of this test gives us and our broadcast partners confidence that we have a flexible and workable path forward to support multilingual public alert and warning in this country.”

11/17/15 - The FEMA continues to roll out regional tests of the IPAWS system. This time, on November 17th at 4:20 EST, the NPT test sequences will be sent to stations in Wisconsin, Minnesota, Arizona, New Mexico, Utah, and Nevada. The location code PEP code will also be part of the test, although the 000000 apparently will not be used as it is not required until next year. There will again be several online seminars available to answer questions. Check with for details.

8/10/15 -  The FEMA is planning an New England IPAWS test in September (16th), in coordination with state broadcast associations in CT, ME, MA, NH, RI, and VT.  The test, at 2:20PM EDT will test the NPT code. There will be an online seminar on September 3rd at 10 AM EDT to answer questions.

7/13/15 -  The IPAWS CAP RMT did not run today in the EDT Zone.

6/30/15 -  The clock has stared on the R&O items below, as the FCC published them in the Federal Record. There is already some pushback on the ETRS and audio follow video crawl. It remains to be seen if the equipment can be put in place on the the FCC's timeline. FYI: Monroe Electronics (DASDEC) EAS boxes are already programmed for the 000000 and NPT. And, both Gorman-Redlich and TFT have stated that their CAP converters handle the 000000 and NPT.

6/2/15 -  Only 3.5 years after the National EAS Test, the FCC has released four proposed improvements to the EAS, in its 6th Report and Order.  Among the FCC's proposals:

  • Within 12 months: designate 000000 as the code for a National Alert (EAN) - and require the use of the code.

  • Within 12 months: require the ability to use NPT for future national tests, such as the one the FEMA says they are planning.

  • Within 60 days: Require use of an FCC website to report test data, which would be used in a mapbook to visually demonstrate the propagation of tests.

  • Within 6 months: Require TV stations to standardize and use tones and crawls to make sure all viewers/listeners can understand any emergency information, even outside of EAS.

  • Sometime: require the FCC and the FEMA to cooperate.

5/18/15 - The Enforcement shoe has dropped on iHeart Media for the false EAS tones (a repeat of the National EAS Test) run on the Bobby Bones Show in October 24, 2014. The Order for $1 Million in civil penalties (plus a compliance plan) was agreed to by iHeart Media to conclude the matter. It is worth noting that part of the reason for the large settlement was that the program was more than just on locally in Nashville (WSIX) - it was on satellite and carried in a number of markets.
However - it is also worth noting that none of the other radio/TV/cable stations that ran the EAN were - or will be fined. Officially, under the current - non-new-rewritten Part 11 that the FCC has been promising for years - Rules, an EAN must be relayed, but header information was to be observed.  That would have prevented the fake EAN from running. But, in typical bureaucratic manner, in reaction to a slight delay at some stations in the 2011 National Test caused by a programming error at the FEMA, a more recent Policy statement and part of the NPRM for Part 11 now says stations are to run an EAN immediately, regardless of the timestamp.
This will need to be sorted out in the - eventual - new Part 11.

5/5/15 -  The CAP RWT for the American Samoa time zone was not sent this week.

4/1/15 -  Are you ready for the National Public Alering System (NPAS)? No, this is not an April Fools' joke. The NPAS - or "Alert Ready" - is the Canadian system that is now in full operation as of today.

Similar to the EAS rules in the US, the Canadian regulatory agency (CRTC) requires most all radio/TV/satellite/cable/video-on-demand stations to participate in NPAS and broadcast alerts where there is danger to life or property. (There is a one year extension of time for campus/community/ native broadcasters and "radiocommunications distribution" services to comply with the requiremen.)

You can listen to the Canadian Alert Tone here.

Receiver and alerting gear similar to that in the US will be in use, however it appears that broadcasters will have less option in relaying alerts. There is even a national message aggregator, similar to the US  IPAWS. The government plans to spend about $2 million on a national marketing campaign to inform the public and encourage them to visit the Alert Ready site, which contains explanations, video examples, and links to agencies that can help during emergencies. 

Complete information - including the new rules - on the Canadian NPAS can be found here. Among the interesting facts are that there are 153 event codes (approximately three times as many as in the US) and that SGC (geo-codes) are used which, unlike FIPS, are able to zero in on a very tight localized area, or wide regional spread, as needed.

3/31/15 -  "Something" happened with the IPAWS CAP RWT this week. Details are sketchy, but someone from the PSHSB noted it was apparently confined to Comcast cable systems. The official word was: "Yesterday [Monday] at 11am EST Comcast inadvertently released a FEMA [IPAWS] EAS Test Alert to a limited number of its devices. This was not a national issue and affected only certain states." It appears mostly in some Eastern states, but also some as far away as California and Nevada TV stations received and broadcast an odd RWT.

3/24/15 -  The Part 11 re-write is coming RSN.

2/9/15 - If you are in the Eastern Time Zone and did not receive an RWT from IPAWS, do not worry. The FEMA did NOT send a CAP RWT this week. Just mark your EAS log appropriately. (The other zones appear OK.) 

2/4/15 - IPAWS will do a live test of the NPT code for broadcast and cable operations on Wednesday, March 18th at 2:30PM EST in the following four states:
                 Michigan  -  Ohio -  Kentucky - Tennessee

The FEMA has planned a tech webinar for participants. It is scheduled for next Wednesday 2/11, at 12 Noon, EST, to go through device configuration. Here is the link

For DASDEC/One-Net owners, an application note on configuring the autoforward for the NPT event test can be found at this link.

1/20/15 - The FCC has issued yet another warning not to play with the EAS tones. Perhaps you remember early last year when the FCC fined NBCUniversal, Disney/ESPN, and Viacom about $2 million for violations, primarly in regards to a commercial for the movie Olympus Has Fallen, run with unauthorized tones in them. NBCUniversal paid their half million, but the others wanted to have the fines reduced or waived. Instead, the FCC has stood fast, and issued an NAL for $1.4 million against Viacom and ESPN, as well as a Public Notice on the matter.

1/5/15 - The first IPAWS CAP RWT for the new year seems to be a double shot. The Eastern and Central time zones are reporting two RWTs about 30 seconds apart.

11/17/14 - The weekly IPAWS CAP RWT was not transmitted to the Mountain time zone today. This has been confirmed by the FEMA and will appear on their end-of-month report.

11/7/14 - The FCC finally said something about the false repeat of the 2011 National EAS Test. They issued a Public Notice late Friday afternoon. They want to alert stations about the possibility of a "Sunday Surprise" and collect comments on the impact of false alerts, as well as how it happened.

11/6/14 - The false repeat of the 2011 National EAS Test may leave a little "Easter Egg" for unsuspecting stations: an EAN could launch on November 9th, if your EAS receiver is "holding" the alert tones sent out by WSIX last week until the date matches. Ed Czarnecki of Monroe Electronics, makers of the DASDEC EAS receivers suggests that "just in case," stations that ran the Bobby Bones Show should check to ensure the fake EAN is not being held in the alert queue. He has provided a detailed instruction sheet to ensure your station will not have a nasty surprise. The Field Service Bulletin is available here.  DASDEC really is trying to help: they are working on calling all the stations they know have their units.

On another issue: the call to "set your receivers for 'strict time'" or otherwise ignore EANs with defective timestamps, remember the FCC stated multiple times that "immediately" is the rule: 11.51(m)(2) and 11.52(e)(2). MORE TO THE POINT: only one manufacturer has this menu setting, you will waste your time if you go looking for it on non-sage receivers.

11/3/14 - The FEMA advises the RWT from IPAWS was not sent to the Pacific time zone today.

10/29/14 - Reflecting on some of the issues raised by last week's fake EAN, Richard Rudman discusses some key issues raised and his view of the best way forward.

10/24/14 - An EAN (rebroadcast from the National EAS Test in 2011) was launched this morning. The Tennessee Association of Broadcasters (TAB) reported the source was a board operator a Nashville FM station, relayed by satellite to other markets, including Atlanta GA, Detroit MI, and Austin TX. (Some screen shots of TV alerts can be seen here.)

The tones from the test were dated November 9th and from "COMCAST" ... but it originated, as you can hear here, on the "Bobby Bones Show." On the audio track, the "talent" is making some comment on the previous night's baseball game, but goes way off the reservation with the tones. Curiously, if he had done as he said, replayed a local area test, it would not have gone very far. But the FCC has said that EANs should be carried immediately.

(Note: The FCC has stated that EANs must run "immediately," regardless of time-stamp. We would remind our readers of 11.51(m)(2) and 11.52(e)(2), among other statements.)

This story will continue!

10/20/14 - The RWT from the FEMA IPAWS: Today's test missed the Central time zone. Reports of "normal" reception have come from the East and Mountain time zones. Reports from IL, IN,  MN, and WI all say no RWT was received. An acknowledgement from the FEMA confirmed. (One report indicated that the Eastern time zone got two tests: 11:01A and 11:03A.)

10/3/14 - Today, the FEMA announced that they missed the RWT for Alaska on September 15th.

9/17/14 - The test in West Virginia seemed to go off pretty well. The first reports in are that most of the decoders got the test OK, and the text to speech worked just fine. (As expected, a few filters were not set correctly, but that is fixable.) As intended, the test appears to have stayed in WV.  

9/12/14 - When will we see the next National EAS Test? Likely in late 2015 or early 2016. The FCC has to adopt the NPT code some additional rules (like mandated reports - the bureaucrat's delight) and ensure cooperation between it and the FEMA.

9/6/14 - West Virginia will be the test bed for the FEMA IPAWS CAP system. A sort of "National" test using the NPT code is scheduled to be done on Wednesday September 17th, except it will be only sent to stations in WV. At least that is the plan. A rebroadcast of the meeting about the test is here.  The WVBA posted this message.

Test Info:
 2:00 PM EDT on September 17. Event Code: National Periodic Test (NPT)
Originator Code: Primary Entry Point (PEP). Location Code: All of West Virginia

8/13/14 - Some stations using Sage gear are reporting problems with statewide tests using audio files unless they are updated to firmware version 89-8. (Otherwise you get Text-to-Speech only.)

7/14/14 - The NPRM for the long-awaited Part 11 rewrite has finally appeared. The FCC is soliciting comments on changes that need to be made to the EAS Rules. Not every rule is in this NPRM, 14-93, which is probably good, as it will speed this action up. Among the items in this NPRM are the location code for EAN, that the EAN must be immediately aired, some new header codes (NPT = National Test), mandating reporting of NPT coded tests (the ETRS), visual crawl and audio accessibility, and a six-month deadline to replace non-conforming equipment. Comments are open through August 14th (Docket 04-296), with 15 more days for Reply Comments.

5/22/14 - The FCC has extended by 18 months the waiver it issued regarding the Wireless Emergency Alert (WEA) PSAs that have been distributed by the FEMA. These PSAs contain WEA EAS tones - which has become a rather lightning rod for fines of late. The FCC says these PSAs may run: The waiver is available here.

DC Attorney Cary Tepper says: "PROCEED WITH CAUTION -- the FCC did not grant an unconditional waiver. The waiver applies only to announcements that 'mak[e] it clear that the WEA Attention Signals are being used in the context of the PSA and for the purpose of educating the viewing or listening public about the functions of their WEA-capable mobile devices and the WEA program.' The FCC warned that 'leading off a PSA with a WEA Attention Signal, without warning, may be an effective attention-getting device, but it would violate the conditions of this waiver because of the effect that it could have on the listening or viewing public.'"

Tepper urges folks "to screen all FEMA PSAs containing an emergency tone to ensure it is a WEA (and not an EAS) tone, and that the PSA meets the FCC's waiver conditions and therefore does not pose a risk of confusing the public as to whether an emergency is actually occurring."

4/21/14 - Tthe IPAWS CAP RWT did not run in the CDT zone. Information from the FEMA indicates that this time zone was missed during the test this week.

4/14/14 - From comments at NAB: The FCC plans the NPRM on the Part 11 rewrite to actually happen later this year. Stations should make sure their EAS gear is behind a firewall, to reduce possibilities of hacking. There has been some discussion with the NWS over message flooding. And, they will be more aggressive on the use of EAS tones and soundalikes in spots.

4/6/14 - DASDEC EAS firmware has been updated to Version 2.5-0. It is available at:

3/11/14 - Still waiting for the Part 11 re-write? You may need to wait longer. The FCC released a Public Notice today, seeking comment on EAS issues such as supporting multilingual information matters. If you desire to comment, you can do it on line, on the ECFS. (The Cocket number is 04-296)

3/7/14 - This has been a real strange week for EAS. "Leaking" Live Code tests, fake EAS tests, and even a couple that no one can account for in public. The latest news is that Kingsford Charcoal is planning to release an ad on Monday that contains EAS Tones.  It is the advice of the NAB, among others, not to run this spot!

3/5/14 - Today's live code test in IL appears to have "leaked" somehow into parts of Indiana - both on broadcast stations and cell phones. There is no complete explanation as yet, but it did surprise a number of stations - and likely listeners. Rreports (Yahoo, Fox, suggest it was an old alert from Nov 17th last year. A few folks are trying to trace this back,

Live code (real, regular EAS Codes, not DMO) tests have been announced for a number of states. Currently:
           On March 4th, KY, IL, and SC had a TOR test.  (Some stations in NC reported the alert)
           On March 6th, MO plans a TOR test.  (moved from 3/4)
           On March 11th, VA will do a TOR test.
           On March 27th, AK will do a TSW.
           On April 24th, WI will do a TOR.
If you are in or near these states, you will want to be aware and careful, lest it panic your listeners. 
(Alaska, Indiana, and South Dakota also have plans for live code tests. AK sends a TSW on March 27th, and a CAE later in the year.)

3/3/14 - OK, one more time: it is illegal to use EAS tones for anything but EAS activations. No movie trailers, no news reports, no silliness. The FCC is not amused. This NAL for $1.9 million to Disney, Viacom, and NBCUniversal push off all excuses - include weasel-wording from lawyers saying it was not "transmitted," or it was not false, or it was "obvious." Broadcasters, cable networks, anyone who transmits or causes to be transmitted the EAS tones will find themselves in hot water. That is the FCC's strong message. Got it?

2/19/14 - Yes, some stations still do not understand the need for an EAS receiver. KBDX-AM in Dallas, TX received an NALF for $9k for not having an operational EAS receiver nor logs.

1/13/14 - The IPAWS CAP RWT was not received by some stations. Reports do say tests were received in EST, CST, MST, and PST. A software issue with the SAGE endec caused users to miss reception. A common comment was:
              Jan 13 18:00:33 VerifyCap: verify_cap exited with error 114
              Jan 13 18:00:33 Validation error for 68628 (114), alert ignored

IPAWS did issue a statement that there was a problem. Sage now acknowledges there is an issue  - a security certificate used to authenticate IPAWS messages has expired in the ENDEC - and a software 89.6 and separate certificate update is pending on the sage alerting systems site.

Checking with other companies: Digital Alert Systems (DASDEC) confirms no certificate issues are forseen for their products. TFT has also indicated no issues are anticipated.

1/8/14 - The FEMA IPAWS office issued a statement to try to resolve some of the comments recently about a proposal floated by FEMA that appeared to indicate a desire to privatize or outsize the IPAWS CAP services. Antwane Johnson wrote that IPAWS "does not anticipate that there would be any changes to the IPAWS-OPEN alert input or output interfaces and no impact to our alert origination and alert dissemination partners beyond normal planned functional improvements."

12/10/13 - The FEMA CAP Server apparently has been operating without major issues over the past month. All time zones report receiving all the scheduled RWTs.

12/1/13 - Several states are now experimenting with voice messages attached to the CAP RWTs. The initial reports are the the audio files are clearer than Text-to-speech. However, clearly this will depend upon the conditions where the audio is recorded.

11/20/13 - Chairman Tom Wheeler has announced his choice to head the PSHSB (Public Safety and Homeland Security Bureau) and replace RAdm Jamie Barnett. The new Chief will be RAdm David Simpson.

11/5/13 - The FCC finally has issued more than a mere Public Notice regarding the use of EAS tones (and sound alikes) in ads, promos, and programming. Bottom line: it is illegal. A rather large fine has been proposed for Turner Broadcast for violating this rule. And a Bowling Green, KY station agreed to make a $39k 'voluntary contribution' to clear them running EAS tones in a commercial.

10/21/13 - Sage has released a firmware update: V89.6 to solve a problem with text to speech. Other recent updates involve issues such as IPAWS polling. The update. And some information on updates. (Thanks to: Todd Hausser)

10/14/13 - As reported, the FEMA decided the RWT was not "essential" during the partial federal shutdown, and did not run it. Nothing official will be offered until the end of the month, but all time zones reported no RWT this week.

10/7/13 - Thus far reports indicate FEMA ran the CAP RWT this week as scheduled, despite the other silliness going on in Washington, DC this week. We must give credit when due!

9/25/13 - Richard Rudman says: "It is a good thing when the National Weather Service (NWS) warns the public when bad weather threatens life and property. Yet,some EAS participants are wondering if there can be too much of a good thing. Some parts of the country are experiencing many NWS EAS weather warnings in very short periods of time that, despite their good intent, may be excessively disrupting programming and driving listeners and viewers away. The Broadcast Warning Working Group (BWWG) wants to find out if EAS participants are cutting back on the number of NWS EAS events they relay. They have created a short survey to find out. Here's the link to the survey:

The BWWG will report back with the results of the survey.

9/24/13 - The FCC has issued a Public Notice inviting comments on equipment and operational issues related to the first National EAS Test in November 2011.  Comments are due by October 23rd. The Docket Number 04-296. The Public Notice is located here.

9/23/13 - We have reports of missing CAP RWTs today. On good authority we can tell you that the scheduled RWTs seem to be missing for the Eastern, Mountain, and Pacific time zones today. Apparently FEMA sent only Guam, Atlantic, Central and Alaska time zones thus far. Any missed CAP RWTs will be listed in the monthly summary provided by FEMA. (You do not get the monthly summary? Sign up here.)

9/17/13 - Nebraska conducted a CAP text-to-speech test through IPAWS. Most stations reported success. A number of states are now running with CAP tests through the IPAWS server. Stations are cautioned to check the logs carefully to see where the tests come from - as it is no longer always the national FEMA folks.

9/2/13 - Perhaps in honor of Labor Day it was a day off at the FEMA. They have now confirmed that they did not issue an RWT as has been the custom on Mondays.

8/9/13 - Interested in a summary of the state of EAS in mid-2013? Richard Rudman presented this information to the Texas Association of Broadcasters this week.

8/9/13 - The National Center for Missing and Exploited Children (NCMEC) has come out with a "quiet hours" directive for AMBER alerts for WEA between the hours of 10 PM and 7 AM.

7/22/13 - This week's FEMA CAP RWT failed to connect in Connecticut due to an incorrect FIPS code. Apparently a digit was left off the state code.

7/15/13 - The FCC has rejected waiver requests from three companies for not having installed new EAS Receivers (CAP Compliant) by the June 30, 2012 deadline. Each appeared to have waited too long to get their receivers ordered in time for delivery before the deadline. There was no specific fine nor indication of when/if the FCC would issue such a fine, but it was made clear that waivers have to meet a very high standard to succeed.

7/15/13 - Reports this morning indicated the Weekly test in the EDT zone went missing due to a programming error. The IPAWS CAP Server was up, but the EDT test was not sent. This has been confirmed with the FEMA folks.

7/9/13 - Several publications, including ZDNet and Wired have reported security holes in DASDEC EAS boxes. This is old information, as DAS had released firmware in April to resolve any issues. More information is here. All DASDEC units should be updated to V2.0-2 at the DAS site.

6/10/13 - There are widespread reports from around the country that there have been glitches in the IPAWS CAP Server this morning during the overnight hours and at 8:45AM, 9:09AM and 9:46AM EDT. Several stations in the CDT time zone reported not receiving the weekly test.

6/6/13 - Monroe Electronics/Digital Alert Systems released an advisory to remind stations about ensuring security for their EAS codecs - and to be sure they have the latest software update. A discussion of the "Zombie Alert" and related issues is located here.

5/31/13 - The FCC PSHSB has rather rapidly released an Order which permits playing the FEMA/Ad Council ads for cell phone alerts. The waiver is for a year.

5/30/13 - It really is hard to know how to react to this one. Remember the FEMA web page with "useful advice" on what to do in an emergency (How checking local radio stations was at the end of the list)? Well, then you may be non-plussed to see this new PSA (there are similar radio spots) that the FEMA expects broadcasters to run, telling people that they can rely upon cellphone alerts to make them secure. (The people in Norman, OK will be glad to tell you how useful cellphones were after the tornado hit. And, even when they work and the cell companies transmit - which many do not - the WEA message is limited to 90 characters. Then what? )

But if that were not enough, included is a free violation of the FCC Rules (11.45). Although some reports indicate the tones have been made shorter and lower in level, several state associations have already told their members to pull any such spots that they have in house. We will leave it to you to ponder this one.

5/29/13 - There is another software update for the Sage digital EAS boxes; 89.5. This update is to correct some issues with CAP Audio, especially when over one minute in length. Those of you on DASDEC boxes can get their 2.02 update here.  If you have not updated your EAS boxes, you should, to ensure good connection to the FEMA server.

5/28/13 - The FEMA IPAWS OPEN CAP Server was done this morning from approximately 02:57 to after 9AM EDT. It appears there were differing times in different time zones.

5/14/13 - A number of stations reported intermittant CAP service today. It was across the country, but it appeared that only a portion of stations were affected.

5/2/13 - The PSHSB (Public Safety and Homeland Safety Bureau) of the FCC has issued a statement encouraging the SECC's to update their state plans and monitoring assignments. An outgrowth of the recent report on the National EAS test, the FCC wants SECCs to review Section 11.21 and ensure it is up-to-date. Some changes may only need informal latters.

5/2/13 - The FEMA and Premiere Networks are working on a plan to provide an additional data path to stations from the IPAWS OPEN server. A date for implementation has not yet been announced, but most observers see any additional options for receiving the CAP messages is good for the industry.

4/18/13 - The IPAWS CAP server was down today from 7:59 to 8:16AM EDT

4/12/13 - You may breath again! All those of you who have been holding their breath, waiting for the FCC's report on the National EAS Test. It was released Friday - just after the NAB Spring Show.

  • The FCC called the test an overall success.

  • Audio quality was poor due to a FEMA connection issue.

  • 13,787 broadcasters reported - and 83% said they got it and relayed, even though the audio was poor.

  • Three PEP stations did not get the test, and those regions missed it.

  • The abrupt shortening of the test made it less useful for diagnostics.

  • Some EAS boxes did not perform as expected, but did as mandated.

  • Another national test is needed.

  • Additional audio paths need to be explored.

  • A number of monitoring assigments were apparently not correct.

  • The FCC needs to move to get Part 11 updated, and receive updated State and Local plans filed.

  • The FCC suggests initiating a web-based reporting system for EAS tests.

3/13/13 - Monroe Electronics and Digital Alert Systems have delivered the first CAP-enabled receivers for Canada's multilingual NAAD (Net Alert Aggregation and Dissemination) system. Fully functional in English and French-Canadian, the DASDEC and R189 One-Net systems can provide CAP-driven audio announcements for weather alerts and civil emergencies. The DASDEC now handles English, Spanish, and Canadian-French.

3/11/13 - The IPAWS CAP server was reported up and down this morning, for example: from 8:25 to 9:22AM EDT and 9:31 to 9:42AM EDT.

3/7/13 - This past Monday's RWT from the FEMA was not received by some users with DASDEC EAS receivers. The focus on what happened is on a minor issue with the scheduled software update that was made to the IPAWS aggregator last week.

If you did not get the test, just note it "failed" and determined that it was not a local problem.

Broadcasters should not be unduly worried at this point, as a software update will certainly be forthcoming to fix things. Whether or not everyone will receive next Monday's RWT from the IPAWS CAP server as usual will depend on how things are handled.  More information will be posted as available.

3/6/13 - TFT has received Certification from the FCC on their new EAS911+ CAP-enabled EAS receiver. The unit has also complete FEMA compliance testing for CAP decoding. TFT will be showing the product at the NAB Spring Show next month.

3/5/13 - Another movie trailer - for "Olympus Has Fallen" - is running around the country with EAS tones included. While the tones have not yet been reported to contain any useful information, it is a violation of 73.1217 - it may be worthwhile to inform your traffic/sales/management. (The producer is supposely doing a remake without the tones - but check which version you may be airing!)

2/28/13 - The FEMA has finally responded to many requests by the BWWG and others for delivering information on the IPAWS OPEN server status and the occasional issues. They have set up a mailing list which also will inform users of the status of the weekly tests, so users can compare with their local logs, and information on when problems occur. To sign up, go here. 

2/26/13 - A web seminar has been scheduled for Wednesday, March 6th to discuss the state of the public warning systems and how to improve them, especially on the state and local level. The time for the broadcast is 2PM Eastern time. The link to the broadcast is here.

2/26/13 - NPR is in the midst of a study to see how stations can better serve deaf persons with EAS messages. Methods may include strobe lights or vibrators actiivated by RDS signals.

2/26/13 - A scheduled outage of the IPAWS OPEN CAP Server has been announced for Wednesday 9:30 to 10:00 AM EST tomorrow (Wednesday) 2/27. There is to be a software upgrade.

2/25/13 - The FCC has renamed CMAS as WEA - Wireless Emergency Alerts.

2/12/13 - Here is a bit more of what facts we know about the fake EAS event Monday:

  • Of the six stations affected, all were either without firewalls or using improperly provisioned firewalls.

  • Of the six stations affected, all were still using the default password.

  • A threat by "Anonymous" to disrupt the President's speech on the Internet drove a lot of high level activity.

  • The vast majority of stations are not in any danger of attack in the same way.

  • SECCs, LECCs, the FCC, and the FEMA need to consider what other adjustments need to be made to provide a higher level of security to the entire EAS, and prevent a cascade "prank."

  • The main threat has been - and will continue to be - to the Internet connectivity of any business. If your company has not previously looked at the logs of "attempted entries" to your system, do so, and be enlightened. Remember: most stations now have some sort of IP connection for remote control, consoles, processors, and more. All of these need protection.

2/12/13 -

  • The intrusion was not a "general hack."

  • It was not an exploit of a known vulnerability.

  • It was a penetration into a station's network and then a logon into their EAS receiver.

  • It appears a YouTube video from 2009 (note the comments), was the source for the mp3 that was uploaded to the EAS box.

Key point: The unauthorized EAS device access and subsequent alert happened because the system was still using the factory default password. While no one has admitted to not having a working firewall, one station did claim that their attack was launched from another continent.

To repeat: While it has be indicated the event developed from a breech of a company LAN, the resulting on-air issue was due to the failure of stations to change the default passwords.

  • Please check your EAS box now and verify that the password has been changed!  

  • It would also be a smart thing to check your firewall to ensure it is operating properly to keep non-authorized personnel out of your LAN.

  • Do not connect your EAS box directly to the Internet.

  • If at all possible, do not place your EAS box on the same network as used by any air talent. All it takes is one Trojan Horse, and it is as good as having no protection.

  • If you are unsure of the above, the FCC recommends you unplug your EAS box until it is fixed.

Another problem popped up today. Several stations, and apparently NBC Today played the audio on the air, including the databursts. There have been scattered reports of stations relaying this. It is a good idea to ensure filters are set correctly (fips codes), and the relay time window does not accept outdated alerts.

2/11/13 - Have you changed the passwords on your EAS receivers from the default? If not, please be aware that hackers have managed to penetrate EAS CAP receivers in at least two states and put out a fake alert. Other stations caught it and blocked it in at least three states. Do not operate with your default password! A few sites have video/audio of the event.

2/11/13 - The FEMA advises us that the IPAWS OPEN Server still is intermittantly up and down at 6AM EST. It has been reported to be back up at 9:33AM EST, although some areas reported problems until 2:30PM EST

2/10/13 - The IPAWS OPEN CAP Server went down at 10PM EST.

1/16/13 - Lamar Smith (KDWN Las Vegas) was the latest to be added to the PEPAC (Primary Entry Point Advisory Committee), The ten member committee helps bridge the FCC and the FEMA with the PEP (Primary Entry Point) stations in each state.

1/10/13 - The FCC report on the Derecho storms last year have a couple of interesting points. While they "like" what the broadcast community does, the writers also appear to think 911 and other alerting methods like CMAS are the future. 

1/10/13 - A  presentation at NAB by the FEMA's Wade Witmer and representatives from NOAA and the cellular industry discussed the state of alerting, especially the current CMAS rollout. Some of the topics included the rather difficult time the cellular industry is having getting the right messages to the right subscribers.

1/9/13 - EAS ALERT: If you were wondering when the FCC was going to enforce the requirements for stations to monitor IPAWS OPEN CAP feeds, wonder no longer. An NOV was issued to KPRI, San Diego for not having records of monitoring the CAP feeds nor reasons why tests were not received.

12/31/12 - Another IPAWS OPEN outage has been reported, starting around 9:30 AM EST.  It appears to have been completely restored by 2:30PM. The outages seem to be different in some areas. e.g. The MST Monday test was received normally.

12/24/12 - The FEMA IPAWS OPEN server was reported to be up and down approximately 8:32PM - 12:20 AM EST

12/20/12 - Another "rolling restart" was apparently done successfully.

12/17/12 - The FEMA plans a "rolling restart" of the ATOM server at 3 PM EST today.

12/14/12 - The IPAWS OPEN server is reported down at 4:24PM EST. Restoration appears to be at approximately 5:22 PM EST. What was described as a "rolling restart" process did not, and a manual restart happened. The FEMA is looking into what happened.

12/12/12 - The IPAWS OPEN server went down today, but without any advance notice, at 11:23AM EST. Complete restoration was finally at approximately 12:45PM EST.

12/11/12 - The FEMA has been doing an upgrade on the IPAWS OPEN server. It was supposed to take a few hours today (Tuesday), but late at night, there was information that there was a snag, and the installation of a mirror server would have to be done another time. The plan for an "active-active" system with rollover, is hoped to prevent any systemic outages in the future - one of the two servers always being active and an automatice "failover" going into effect in case of problems.

(Prior known outages of the FEMA IPAWS OPEN server are located here.)

10/29/12 - Hurricane Sandy smashed into the East Coast today. Few EAS messages were sent, as it was pretty clear this was coming and the wall-to-wall coverage on the TV nets and many "full service" radio stations pretty much informed everyone. On the other hand, the FCC and FEMA have other ideas on how you may wish to communicate - or at least some might think the priorities are a bit upside-down. At least they got to radio. Broadcasters should feel "special."

10/26/12 - The New Jersey Broadcasters' Association reports that the state's EAS systems suffered a major outage after a lightning strike caused major issues with new EMnet system. A backup trunked radio system also failed at the same time, prompting calls for more periodic testing to ensure both the EAS and backup systems were always ready.

10/15/12 - For those of you who wonder how tests of emergency alert systems work in other countries, perhaps it will provide a small sense of perverse comfort to know that having problems during national tests is not confined to the US.


The FEMA has listened to requests from the BWWG and the broadcast community and announced the IPAWS OPEN RWTs will continue TFN.
These tests - scheduled for Monday at 10 AM local standard time (11 AM DST) for the main time zone in each state - will be initiated by the IPAWS OPEN CAP server each week

Exactly does it mean for a station to be "compliant?"
Each station must purchase, install, and make operative an EAS receiver capable of receiving CAP/EAS messages. The most important change from previous operation is that a station must be connected to the IPAWS CAP server and receiving data. That, of course, requires the new generation of decoders and a wideband Internet connection. At this time, none of the various state/area aggregator tests are required. This will change as state and local plans - or amendments - are filed with the FCC but, as of now, in most places, you are only adding the CAP/EAS to your existing state plan.

Do you have to log the tests from the IPAWS server?
Yes.  ALL TESTS FOR YOUR AREA that are received - and decoded - should be logged, according to the FCC. Tests from other states/areas that are not in your decode chart are not required.

If there is a problem with the IPAWS RWT tests, what should be done?
The FCC currently says that stations may just put "Did not receive RWT from IPAWS" or some such notation. If you know why there was a problem, add that. However, there is no urgent need to search out and log the reason. If we know of any IPAWS OPEN issues, we will note them above.

Will the FEMA have a web page to explain problems/errors?
According to the FEMA, not at this time. Their main concern is that you have a "connected" status. Beyond that, they will distribute information as available, but not necessarily on any schedule.

How often should you poll the IPAWS server?
Some suggestions range from every 30 seconds, to 60 seconds, to as long as 5 minutes. At this time it is up to the station. A slide on a FEMA presentation says 30 seconds. Some receivers default to 60 seconds. In the future, when state and local alerts may be transmitted by CAP, some may feel there is a need to be on the slower end of the scale, but many system experts say 30 seconds is too often.


The three most common problems for those installing new EAS receivers:
1. Make sure you have the most current software.  (Especially Sage owners)
2. Have the IPAWS server name (FQDN) entered in the setup.
3. Ensure your firewall will allow you to poll the server.

If you still have issues, contact your receiver's tech support line. 

7/9/12 - Sage owners: there is a software glitch that causes the receiver to lock up. It may be related to momentary loss of connection with the IPAWS or CAP server. A reboot usually resolves the problem. Sage has indicated they will have a software update to try to resolve this issue (Version 89.2).

12/22/11 - The FEMA has released a new online course designed by Integrated Public Alert and Warning System (IPAWS), for emergency managers and others. The course, IS-247, is designed to support and test skills needed to draft more appropriate, effective, and accessible warning messages and to teach practices for the effective use of Common Alerting Protocol (CAP).
Anyone can go through the course and file the test, seeking certification. (It will also give broadcasters an idea of what local EMs are expected to know.)

The FEMA expects to require this training for all emergency warning centers before they are permitted to upload warnings to the FEMA OPEN aggregator server. Completion of IS-247 will also be required for any alerting official to send an alert via IPAWS, and is also to be made part of the NIMS (National Incident Management System), and certification being required in order for agencies to get federal funding.


Definitions  (if all those abbreviations and acronyms confuse you)       back to the top


  • Q: What is now required to be on the EAS Log each week?
    A: Each station must receive an RWT each week from each monitoring assignment (LP1, LP2, NWR, IPAWS OPEN, etc) as required by the FCC or as noted in the current State Plan. Each station must send an RWT each week.  Once each month an RMT must be received and relayed.
    If a test is not received or sent, a notation must be made in the EAS log acknowledging the failure and the reason for the failure, after the Chief Operator investigates.
  • Q: Is it true that the FCC requires that OTA (over the air relay) must be used when crafting EAS local and state plans, and will continue that requirement when Part 11 has been re-written.
    A: Nowhere in Part 11 is it stated that EAS plans must use OTA systems to propagate EAS messages. Wireless state and local relay networks (LRN's) can (and in the opinion of the BWWG should) be used as point-multi-point distribution means for EAS from warning centers to as many broadcast and cable entry points as possible. There will be exceptions, but OTA Relaying of EAS messages (Daisy Chain) is a carry over from EBS and is (and should only be) only used by those who choose to continue to do so in their EAS plans because there is no other alternative.
    Washington state and some other areas are already implementing various forms of LRN's for CAP (Common Alerting Protocol) EAS. At the Federal level the need for relay using CAP should end when all entities subject to Part 11 have their CAP boxes installed and have programmed in IP addresses so they can poll CAP message aggregators. OTA Relaying of EAS messages (Daisy Chain) is a carry over from EBS and is only used by those that choose to continue to do so.

  • Q: Does CAP automatically play embedded audio files for the voice portion of CAP-EAS messaging for broadcast?

    A:  No. At TV stations the CAP Text Message data stream generates a video screen crawl. The data stream also generates  audio from a text-to-speech feature built into the EAS box. Radio uses the text-to-speech feature. This completely eliminates the problems with poor audio quality for "Classic EAS".  Yes, CAP messages can carry embedded audio files, but to get around payload/throughput problems they can be posted for download and referred to by putting their URL's in the CAP message.

  • Q: What about the CAP Converters?
    A: Several manufacturers have produced add-on boxes that will decode the CAP transmissions and feed them to an existing EAS receiver. At this moment, that seems to satisfy the FCC's requirements.
  • Q: What has been settled?
    A: CAP V 1.2 has been adopted by FEMA. The CAP is a very powerful tool that can really improve warnings. (Want to know more about CAP? CAP V 1.2 is described here, 3rd entry from the top.)
  • Q: Will there be changes in Part 11?
    A: Yes.  This is one reason some manufacturers have held back in production of EAS boxes, until the all Part 11 changes are known. The FCC has called for comments and promises to release the Part 11 changes "real soon now." 
    There still remains a big missing link in Part 11 - there is still no firm connection to local emergency management to make sure that warnings and tests originate properly from the people who have the real responsibility to warn -- i.e., the emergency managers. It is doubtful Part 11 will ever have this included without Congressional action for any number of reasons.  

  • Q: Who is in charge of EAS: the FEMA or the FCC?
    A: A very good question. A fair part of the controversy right now is that FEMA IPAWS was originally designed to cover only federal issues geared to federal government continuity, not local/state warnings, mandatory governor level and governor-designee messages, or even AMBER Alerts.
    IPAWS scope was extended to the state/local level after prodding by the BWWG, NAB and NASBA, but all the pieces to make this a reality are not in place yet. The FEMA's work to date also does not take into consideration all the elements of state and local concerns that are definitely part of the FCC's Second Report and Order on EAS. This disconnect needs to be worked out.

For those worried about the requirements in Part 11 about the State Plan and State Map, the FCC is not expecting new State Plans. At this point, they are asking for "Amendments" to existing plans - and the maps are for a future time.


2/25/13 - The FCC has renamed CMAS as WEA - Wireless Emergency Alerts.

6/28/12 - National Weather Radio is now sending out weather alerts to mobile devices that are enabled to receive the CMAS. These alerts - various warnings - announced on the NWS Home Page are in CAP and will include Tornado and Flash Flood Warnings, Hurricane, Typhoon, Dust Storm and Extreme Wind Warnings Blizzard and Ice Storm Warnings, and Tsunami Warnings. More information is on the NWS site here. A chart of the warnings is here.  News reports indicate some alerts have already been sent/received in different parts of the US.


More info on the National EAS Test is archived here.

1/26/13 - The FCC still has not finished its study of the November National EAS Test.

10/15/12 - For those of you who wonder how tests of emergency alert systems work in other countries, perhaps it will provide a small sense of perverse comfort to know that having problems during national tests is not confined to the US.

11/29/11 - FEMA held a web broadcast to officially announce the National EAS Test was a success. Diagnosis for the problems with the audio during the National EAN Test - the output of an EAS encoder being backfed into the conference bridge - placed blame on the failure of the FEMA Failsafe (... see the item dated 11/12/11 below).

During the discussion, which saw a number of questions raised and discussed, FEMA and FCC representatives said they learned a lot from the test - and after they finish reviewing the reports, plan to issue the new Part 11 Rules.

The three-minute delay experienced by some EAS receivers holding the test until the time programmed in the headers (2:03 PM) was explained as an incorrect setting on the FEMA encoder.

A highlight of the discussion was when Suzanne Goucher of the Maine Assn. of Broadcasters revealed that Senator Susan Collins (R-ME) plans to introduce legislation in the US Senate to direct FEMA to officially authorize the IPAWS program created by President Bush in 2006, but never made into law. The Bill would create an advisory committee to direct EAS training by FEMA would be incorporated into the National Incident Management System (NIMS); all entities wishing FEMA funding would have to be trained on EAS operations. FEMA funds would be allocated by law for this, to ensure some Congressional oversight of the IPAWS program.

Other information mentioned during the broadcast included mention that another National Test will be planned, likely next year; the need to deal with the sociology of warnings where people tend to ignore them; the need to deal with the TV/Cable issue where systems force-tune viewers to one feed, rather than letting viewers stay with local stations; and suggestions that future tests have clear goals and a definition of success or failure set out before the next test.

A Note to everyone: We could sit here and give you paragraphs of quotes from people who thought the National EAS Test was "the best ever" or "a total failure" - and everything inbetween. We could relate some of the finger-pointing that has gone on, from bureaucrats to the Congress - and our opinion of that. However, we are not sure that helps anyone.

If the test had been run by broadcasters, you would have known the problems and solutions within hours. Unfortunately, things do not run quite that fast inside the Beltway. So, until the web broadcast where the FEMA says they will discuss their extensive post-test testing, you may find the explanations below sufficient. When there is a clear narrative of the path ahead, you will find it right here. (Feel free to bookmark this page, we will post something as soon as we know it.)

11/15/11 - Following the National EAS Test, Rep Greg Walden, R-OR, has announced he plans "bipartisan hearings" on Thursday at the House Communications Subcommittee to question the FCC and the FEMA. Noting that most of Oregon did not receive the test, Walden's sub-committee will ask "what worked, what didn't and where we can go to fix it."

11/14/11 - A hacker in San Francisco has given Anonymous code that could place a fake EAS message on the air.

11/12/11  THE ANSWER to the audio mess!

        After analyzing the EAN audio, it has been confirmed that a hardware failure related to the FEMA Bridge at a PEP station - WCCO - was the cause of the audio loop back to the FEMA sending source - a conference bridge. That affected most everyone who got their test via a path from the FEMA PEP bridge and explains why the audio from sample points around the country are very similar.

            If you follow the stations in the chart below, there seems to be some correlation between the decoders that worked and those that did not. There were two aspects that appear to be involved:

  1. The headers. A receiver needs to decode two of the three data bursts to initiate a valid alert. If the signal or audio is marginal, this could cause only one data burst to be "recognized" ... which on some machines (the digital Sages, for example) would cause whatever was on the air to be stopped - then silence until the EOM was received.

  2. The audio levels. It seems like some receivers were very touchy on audio levels, causing distortion that might make it harder for the bursts to be decoded.  Previous tests had shown most EAS receivers could decode bursts with significant distortion, but some of the newer digital machines apparently had trouble if the levels were not in a narrow range.

        Reports also indicate that some with DASDEC receivers got the audio and WAITED
 until 2:03 EST to play the EAN, just as the receiver was designed - to react to the time stamps on the alert. One state was late into their test as the feed from FEMA was unexpectedly lost, and that or something similar may be part of the lack of audio in two other states. Oregon Public Broadcasting was said to have had technical issues, preventing most stations in the state from getting the test.

         We are still chasing down what happened in the places where no audio was received at all.  It does seem that some EAS receivers, upon receipt of a header, mute audio. If, it is postulated, the rest of the header was not decoded properly, it could have left the stream with no audio.  More answers are expected, as the bureaucrats say, RSN.

In the meantime, we will try to offer some more diagnostic info for any of you who want to do more analysis. Here is some other audio,as recorded around the country (if you can add to the information, please let us know!):

       Twin Cities Public Television, Minneapolis, MN

Don Heppelmann says: "The bottom four boxes are KSMQ-DT in Austin Minnesota.
TCPT provides their master control, but they do their own EAS.
The Four middle boxes are Comcast, DirecTV, Dish, and Comcast.
The rest are Twin Cities Public Television over the air services."



   FIRST OF ALL:  It was a test!  It was only a test!  No matter what the national media or Lady Gaga lovers say, it was a test. It was largely, in that sense a success, because if nothing else, most every receiver got the header and opened.  If nothing else, it is much clearer what needs to be fixed.  And, since most of the EAS is volunteer, it gives some impetous to make some changes in the relationship between mandated broadcasters and the feds.

    Audio from NPR shows that the "echo" and the looping may well have started at FEMA. There is some thought that the way EAN works is that when the header came around again, the receivers grabbed it and "overrode" the first test. That would explain the tones on top of the message.

    Some other audio from around the country (the calls may be


     Reports from around the country indicate a lot of things need to be worked on.

        There were tones over audio, low level audio, echo, aborted audio, and more. Some stations only got the EAS tones and no audio. Others got six words and then silence.

      It appears that Oregon mostly did not get the EAN, those that got anything only got tones. This was also reported in Minnesota.

      However, here is the bright side: in most cases, the EAS boxes did receive and decode the EAN headers.  Perhaps it is time now to address the audio chain..... perhaps put some broadcasters on to it???
