Are You Ready for the Aug. 11 National EAS Test?

Radio World
3 years 10 months ago

Radio World has gathered tips and best practices for U.S. radio stations ahead of the upcoming national EAS test.

As you probably know by now, FEMA will conduct its test of the national Emergency Alert System on Wednesday Aug. 11, 2021. It will be fed at 2:20 p.m. EDT via the Primary Entry Point (PEP) Network. (FEMA will also be testing Wireless Emergency Alerts.)

This particular EAS test will not be available on the IPAWS network, because two years ago FEMA did one that bypassed internet connectivity and found some issues on the EAS side. Now it wants to document the effectiveness of the improvements since then.

Here’s what the experts have told us:

-Start by reviewing the FCC Emergency Test Reporting System website, the one it uses each time FEMA conducts national EAS tests. The page includes key information including guidelines for filling out the three required test reporting forms.

-By now you should have filled out Form One. Make yourself a note to file Form Two immediately after the Aug. 11 test (but no later than the next day, Aug. 12) and also to file Form Three by Sept. 27. “I always recommend tackling these ETRS forms early in the allotted time windows,” says Aaron Read, IT/engineering director for The Public’s Radio in Rhode Island. Don’t wait until the last few hours or days, he said; in case of a problem on the FCC end, you’ll have time to call or email the help desk.

-All of our sources agree that you should make sure that your EAS equipment has the most current software version. Check with your manufacturer if you aren’t confident.

-Larry Wilkins of the Alabama Broadcasters Association and chair of the Alabama SECC said engineers should check their equipment for the following items:

  1. Verify that you are monitoring the correct two sources, assigned by the State Emergency Communications Committee (SECC) or EAS committee. The alert will be received by the PEP station or stations in your state and relayed around the state via State Relay networks and the LP-1 and LP-2 stations in your area.
  2. Verify that the audio quality of both sources are broadcast quality (no crosstalk, hum, noise, etc.) and that the levels are correct to match your program audio.
  3. Verify that you are receiving the Required Weekly Test (RWT) from both monitor sources.
  4. Review the incoming filter list in your equipment to ensure there is a filter labeled National Periodic Test (NPT), with the originator set to primary entry point (PEP). The location should be left blank or have 6 zeros (000000).
  5. Verify that your EAS equipment has the correct date and time and is locked to a national time server.
  6. Assign someone to be on hand, monitoring the over-the-air (OTA) signal at the time of the test to verify proper reception and retransmission of  the test.

(Larry’s ABA Engineering Academy also has posted a detailed video specifically to help stations prepare for this national test.)

-Manufacturer Digital Alert Systems released a preparation document to help users of its gear. It also noted, “The NPT is an occasion to perform essential checks on fundamental items, such as checking that the EAS equipment is operating, backup power is functional, the radio monitors are tuned and monitoring the appropriate sources from the state EAS plan, and the equipment’s software is updated.”

It too reminds stations to make sure their devices are synced to the correct time and time zone.

-Manufacturer Sage Alerting Systems reminded stations to check their logs to make sure they are receiving weekly tests from their monitor assignments, and that they have been originating weekly tests and relaying Monthly Tests as required by their license type.

“Make sure your ENDEC has a filter to receive and relay the NPT,” Sage wrote. “The easiest way to check this is to access your ENDEC with a web browser. From the main page, click the Tools button on the left column, then click the ‘Verify Req’ button. If you see ‘Your ENDEC will meet the FCC requirements for the National Periodic Test’ on the last line, your ENDEC is ready.”

-Another reader with experience in EAS recommends that you should monitor the Primary Entry Point even if none of your assignments are the PEP. “Obviously you still need to monitor your LP stations as assigned, but adding the PEP as an additional source is good practice. This does wonders to improve audio quality, which has been the most frequent complaint during previous tests.”

-Not specific to this test but about EAS in general, Aaron Read said, “EAS is a good place to not be cheap. Spend a little more and get the good encoder/decoders, like a Sage or DASDEC, that you can easily access and update remotely over the web. Get the good tuners like the Crown RFBA1 or the Inovonics InoMINI AM/FM/WX receivers,” he said.

“I know it’s an unfunded government mandate and that its usefulness in real terms is highly questionable for many stations across the country; so the instinct is to spend as little money on it as possible. But EAS is one of those things where the less you spend up front, the more you waste in time down the road, and the reverse is also true. And as we all know, time equals money.”

-And R. V. Zeigler, director of engineering for the Nebraska Rural Radio Association and chairman of the Nebraska SECC, offered us this series of tips:

  1. If you have noise issues picking up a terrestrial PEP, Zeigler said, there are also three satellite PEPs: NPR (its Squawk channel), Premiere Networks (its FEMA channel) and Sirius/XM (its non-subscription “Barker” channel). “Communicate with your SECC regarding these options,” he said. “The FCC has approved the use of these sources in state plans.”
  2. Also, Zeigler said, make sure everyone in your stations is aware of the upcoming test. “Reception may get calls. Programming as well as traffic need to be aware of the disruption in normal programming. Everyone else should know as well, in case they get questions from clients or the public at large.” Running a PSA in the days before the test can help.
  3. In fact he suggests you make sure your local Public Safety Answering Point or 911 answering center is aware as well. “Sending the dispatch and emergency management supervisors a copy of the FCC announcement would be a great goodwill gesture. SECCs generally take care of this; but as JFK said, ‘There is always some poor bastard who doesn’t get the word.’”
  4. When you submit Forms 2 and 3, save copies of all of forms for reference when the next NPT comes around.
  5. And last, Zeigler said, relax. “If you have checked everything on your end and followed all of the ideas in this article, you have done your job. This is a test, and only a test.”

If you need more information, contact your State Emergency Communication Committee (SECC), EAS Committee or State Broadcasters Association. You can also send an email to the Federal Communications Commission EAS Test Reporting System desk to ETRS@fcc.gov.

FEMA also has a public-facing FAQ page about the test.

Meet Nielsen’s New PPM “Wearables”

Radio World
3 years 10 months ago
Nielsen PPM Wristband model

In September, Nielsen will begin placing 3,000 new Portable People Meter Wearables in its pool of active PPM panelists.

“PPM Wearables feature an updated design that is smaller and more aligned with current wearable technology trends,” the research company said in the announcement.

Pendant model

“The new PPM Wearable comes in a variety of ways to wear including wristbands, clips and pendants, which are more appealing among demographics that typically have lower compliance. In addition, a new companion app will help improve communication, encourage participation and enable data transmission when the device is outside the home.”

It said the companion app will allow it to add features and adapt to technology trends more seamlessly.

The designs were first introduced in 2019 at the NAB Show. This week’s announcement was made by Mainak Mazumdar, Nielsen’s chief research and data officer.

The new PPMs are seen by Nielsen as providing “foundational support” for its work toward Nielsen One, a platform that it hopes someday will deliver “a single, deduplicated metric for media consumption” across TV, digital and audio, which includes radio.

Clip-on model

There are about 60,000 active PPM panelists, so the first batch will be used by a subset of that population. The company said it will share top line findings in the second quarter of next year for the subset phase, and a full rollout of PPM Wearables in new panel households is planned for the second half of 2022.

“PPM Wearables have been through a series of rigorous tests and the system has performed very well in each phase,” it stated. “These tests included lab, focus group and dual-carry testing that measure how the wearables detect codes versus the current PPM among the same panelists.”

Portable People Meters are used by Nielsen in measuring audiences for audio, including radio, as well as local and national TV. First developed by Nielsen predecessor Arbitron, PPMs are carried by people in the Nielsen panels in larger markets to measure exposure to media.

The Texas Association of Broadcasters said attendance at its two-day annual convention this week was slightly over 1,000, “more than we anticipated and not too far from our normal attendance of 1,400,” according to a spokeswoman.

The event was one of the first in-person conferences for the broadcast industry since the pandemic hit the United States 17 months ago. It was held the JW Marriott in downtown Austin.

Other state associations having annual events in the next five or six weeks include those in Nebraska, Vermont and Wisconsin, as reported on the Radio World events calendar. The Alabama Broadcasters Association postponed its August event to January, as we reported yesterday.

SBE: New Wireless Systems Need Frequency Coordination

Radio World
3 years 10 months ago

The Society of Broadcast Engineers wants to make sure that a new wireless mic technology, if allowed by the Federal Communications Commission, won’t cause spectrum havoc.

The SBE has submitted detailed comments about proposed changes to Part 74 rules that would allow the use of Wireless Multi-Channel Audio Systems in broadcast TV bands and other Part 74 bands on a licensed basis.

WMAS systems have been proposed by wireless mic manufacturers like Sennheiser and Shure, and the FCC has an notice of proposed rulemaking open, asking for comments about them.

The engineering society told the commission it is “not opposed to the use of WMAS technology in the subject allocations,” but it said the use of WMAS in existing wireless microphone and low-power auxiliary service allocations should be subject to coordination with SBE local market frequency coordinators.

It also said WMAS systems should be operated only on a non-interference basis to incumbent wireless mic technologies, especially at UHF, “so as to not reduce further the nominal, residual UHF spectrum available for current technology wireless microphones.”

SBE also said WMAS should not be viewed as a replacement for conventional narrowband systems.

“Finally, the commission should carefully test and evaluate the increase in the noise floor that might result from the overlay of WMAS on incumbent narrowband wireless mic operation, and the effect of any such noise floor increases on the latter facilities,” it wrote.

“Reportedly, WMAS has a greater potential for interference than does current narrowband wireless mic technology, and WMAS has not been shown to be compatible with the large deployment of narrowband wireless microphones.”

SBE said it endorses the FCC’s efforts to encourage spectrum efficiency in the “extremely limited BAS allocations” available for wireless mics and other auxiliary facilities. “However, SBE urges that the commission not view this proceeding as a sufficient response to the critical shortage in available spectrum for wireless microphones, especially in the UHF television bands.”

Its full filing goes into detail about the recent history of spectrum management affecting wireless microphones. [Read the filing.]

SBE concludes: “We are hopeful that the commission will recognize that the authorization of WMAS must be done carefully so as to not further disrupt incumbent narrowband wireless mic operation, especially at UHF, and that the commission should establish as a high priority to make further accommodation for continued UHF wireless microphone and LPAS operation … Moreover, the commission should require that all users of WMAS technology participate in the frequency coordination process established as a service to the industry by SBE prior to commencement of operation at any given location.”

As we reported yesterday, the National Association of Broadcasters gave cautious support to the proposed use of WMAS, calling on the FCC to allow it on a “secondary basis” with “prudent restrictions” on its operations.

UK Looking for Opinions on Relicensing of DAB Radio Licenses

Radio World
3 years 10 months ago
John Whittingdale

The United Kingdom’s Office of Communications is asking for comments about its plan to relicense the country’s two national commercial radio DAB multiplex licenses.

Ofcom is hoping to gather opinions from stakeholders about different roadmaps to renew the national commercial digital radio licenses held by Digital One Limited and Sound Digital Limited. Together those organizations provide access to 40 free-to-air commercial digital radio stations across the nation.

Digital One Limited launched in 1999 and carries three national analog commercial services — Classic FM, TalkSport and Absolute Radio — as well as 17 other services, reaching around 91% of UK homes. Sound Digital Limited launched in 2016 and currently reaches 83% of UK homes. The Digital One license is set to expire in November 2023 while the Sound Digital license will expire March 2028.

The aim of the review is to seek views and collect information in an effort to better inform decisions about the licensing process, said John Whittingdale, OBE MP, minister of State for Media and Data for the UK, who posted a wide-ranging document on the issue. It describes the policy and regulatory issues, lists policy options for consultation and sets out a series of key questions.

He said the goal is come up with a plan that will clarify that the relicensing process for these national radio multiplexes works in the best interests of the commercial radio industry and audiences across the UK.

“We believe it is appropriate to give consideration to the policy on the licensing and renewal of the national DAB multiplex licenses to give the commercial radio operators who use these networks clarity and certainty about the future of the platform and ensure there is no disruption of the services broadcast on the network,” he wrote.

The department is seeking views on three potential options: one, to allow the two licenses to expire and be re-advertised through an open competition every 12 years; two, to amend the Broadcasting Act of 1996 and allow both companies to renew their license until December 2035; or three, amend the broadcasting act so that both licenses have a matching expiry date of December 2030.

A longer renewal term would provide national broadcasters and license holders with stability that in turn would help support the government objective to support a listener-led transition of radio to digital, he said.

A shorter license renewal term would harmonize the expiration dates and allow for a more strategic approach to be taken in regard to the use of broadcast spectrum by commercial radio in the 2030s; for example by allocating more spectrum to national, local or small scale DAB services.

The department is also seeking views on other issues such as whether a renewed license should include obligations for a higher level of DAB coverage, and whether in offering a renewal to 2030 or 2035 there is need for a mechanism to protect stations that are carried on either multiplex from future carriage fees charged by the national commercial radio multiplex operators.

The review period is open now and runs until Sept. 14. Responses can be sent to nationalmultiplexconsultation2021@dcms.gov.uk.

COVID has disrupted another broadcast event. The Alabama Broadcasters Association has postponed its annual conference until January.

“While we are disappointed to have to make this change, it is in everyone’s best interest,” ABA stated in an email. “The surge in the rate of infections and hospitalizations has to be addressed. We’ll all do our part and put off our gathering for a few more months.”

The conference was to have been held Aug. 13 and 14. It will now be held on Jan. 21 and 22 at Ross Bridge Golf Resort and Spa in Birmingham.

Companies of interest to Radio World readers that were listed as exhibitors for the event include BGS, Bonneville Distribution, Dielectric, GatesAir, Nautel, RCS, SCMS, Shively, Telos Alliance and Tieline.

The association said people who have already registered can email ABA either to hold the registration for January or request a refund.

Meanwhile, 680 miles to the southwest, the Texas Association of Broadcasters opened its two-day convention and trade show in Austin on Tuesday.

NAB Supports WMAS, With Restrictions

Radio World
3 years 10 months ago

The National Association of Broadcasters supports the proposed use of a new wireless microphone technology if the Federal Communications Commission allows it on a “secondary basis” with “prudent restrictions” on its operations.

The technology is called the Wideband Multichannel Audio System. It was first proposed by Sennheiser and is being actively supported by Shure, which has made several presentations to FCC staff about it.

The commission has been taking comments on whether WMAS technology should be granted on a licensed basis in frequency bands where wireless mics are already authorized. This includes TV bands, the 600 MHz duplex gap and in portions of the 900 MHz, 1.4 GHz and 7 GHz bands. The NPRM also looks at using WMAS on an unlicensed basis.

In comments filed Monday, the NAB said WMAS could help relieve spectrum congestion in situations where a large number of wireless microphones are needed.

But because WMAS “has a greater potential for interference and is not compatible with legacy narrowband wireless microphone deployments,” NAB said, the FCC should put restrictions in place to “help reduce the potential for interference to primary spectrum users and to ensure that spectrum efficiency is actually improved.”

[Read the full filing.]

Notably, the NAB says the commission should limit WMAS operations to large events.

“WMAS systems occupy more spectrum than traditional wireless microphone systems. As a result, the use of WMAS systems has a preclusive effect on traditional systems where spectrum is limited. For example, if there is only a single 6 MHz TV channel available for use at a breaking news event, one news crew using a WMAS system could occupy the entire channel and prevent coverage by other news organizations.”

So the association said the commission should limit use of the technology to situations where a large number of audio channels are needed and all channels are under control of one entity, such as arena concerts, big sporting events, TV and movie production and major theatrical shows. It suggested that an appropriate threshold would be 10 audio channels in use by a single entity.

“As an added measure, NAB suggests the commission only authorize WMAS base stations that are designed to prevent transmission when fewer than 10 paired audio devices are detected.”

NAB also said the FCC should require a minimum efficiency of six audio channels per megahertz.

“The commission’s proposal of at least three audio channels per megahertz appears to represent no meaningful efficiency improvement, particularly if the audio channels are not of broadcast or production/performance quality. … Based upon marketing information from one of the petitioners, existing digital wireless microphone systems can support at least 47 audio channels in a six MHz RF channel, albeit with some restrictions, corresponding to a spectrum efficiency of 7.8 channels per MHz. NAB understands that WMAS can support up to 64 audio channels in 6 MHz of RF bandwidth, corresponding to an efficiency of 10.7 channels per MHz. A baseline efficiency requirement for WMAS of six channels per MHz would thus represent an improvement upon what is available using existing technologies but be comfortably below the theoretical maximum efficiency of WMAS technology.”

The association asked the commission to restrict WMAS eligibility to Part 74 licensees and to limit the new systems to 6 MHz bandwidth.

And NAB agrees with an FCC proposal to limit these systems to 250 mW EIRP in the UHF television bands, regardless of the bandwidth of the WMAS operation.

“NAB believes this 250 mW power level would be sufficient power to accommodate a large number of WMAS audio devices while reasonably limiting the co-channel interference potential to that of conventional wireless microphone deployments. An EIRP limit of 250 mW also maintains the necessary protection of WMAS to television stations operating on adjacent channels.”

College sports media company Learfield IMG College is simplifying its name. It will now be called Learfield.

The name Learfield derives from co-founders Clyde Lear and Derry Brownfield, who started a farm radio network in Missouri in 1972. A series of business combinations and acquisitions had led to the most recent name, Learfield IMG College.

The company is a media and technology services supplier in intercollegiate athletics; its specialties include sports multimedia rights, licensing, technology and data.

“We think the new brand visually distinguishes the company in the same way that the expertise and passion of our people differentiate the experience of working with Learfield and its affiliated brands,” said CEO Cole Gahagan in the announcement.

The change includes a new logo. “The icon represents the ‘pennant’ prominent in company logomarks combined with a stylized ‘number one’ to create an active L design,” according to the announcement.

Black Lion Audio has launched its PG-P Portable Power Conditioner, built around its proprietary PG-P portable filtering technology.

It says the aim is to provide the same level of noise filtering as found in rack-mount power conditioners.

Black Lion says that the power conditioner is built using Panasonic capacitors, selected to help eliminate high-frequency noise. As a result, the unit provides studio-grade power-on-the-go via six wall-wart-spaced outlets, as well as Ground OK, Protection On and Clean Power On LEDs.

[Check Out More Products at Radio World’s Products Section]

PG-P is available to purchase through Black Lion Audio’s global network of dealers/distributors with a MAP of $69.

The unit comes on the heels of the new PG-2, a pro power conditioner that Black Lion recently introduced, offering a 120 V Power Grid of 14 outlets in a 2U rack-mountable chassis.

The PG-2 sports proprietary PG-99 Filtering Technology, alongside a suite of status and alert capabilities, all of which Black Lion says helps the unit provide an average of 99.7% of noise filtering.

The power conditioner features Panasonic and Wimi capacitors, and offers filtration with a reported power absorption rating of 2,775 joules. Also, the PG-2 features a bank of 12 switched, filtered, and surge-protected outlets on its back panel arranged as three groups — four digital audio outlets, four analog audio outlets and four high current outlets.

Alabama Station Faces Fine for Late License Renewal

Radio World
3 years 10 months ago

An Alabama broadcaster faces a $4,500 fine for not filing for license renewal on time.

The Media Bureau of the Federal Communications Commission issued the notice of apparent liability to Autaugaville Radio Inc., saying the broadcaster failed to file by the deadline required for seeking renewal of licenses for its AM station WXKD in Brantley, Ala., and its FM translator W292HL in Troy.

The applications for renewal should have been filed by April 1, the first day of the fourth full calendar month prior to the expiration dates for the licenses. The commission said the broadcaster eventually filed prior to license expiration, but that it did not explain its failure to meet the earlier deadline.

The company now has 30 days to pay, respond or appeal. The proposed fine consists of the full $3,000 base forfeiture amount for the AM and a reduced forfeiture of $1,500 for translator.

The Media Bureau found no other issues with the license renewal applications, which it indicated it plans to approve once the forfeiture proceeding is finalized.

The Calrec Type R compact console at Athens, Greece’s Pepper 96.6 FM.

Pepper 96.6 FM in Greece’s capital city of Athens has chosen to install a Calrec Type R compact console.

Station Technical Director Anastasios Labropoulos cited the console’s compatibility and flexibility with IP technology as one of the deciding factors, along with “ease of utilization; ease of upgrading software; and last but not least, the number of I/Os and faders.” He singled out the onboard mic preamps as being of “great quality.”

[See Our Who’s Buying What Page]

The small six-fader mixer and screen fit the station’s requirements. “Since we are primarily a music station, we had no need for a larger console; the current configuration of the Type R with specific I/O and faders fully covers our needs,” Labropoulos explained.

Calrec’s Greek partner Bon Studio S.A. provided key services.

Getting a Look Inside the BIN

Radio World
3 years 10 months ago

Tanita Myers is the director of news operations for iHeartMedia’s Black Information Network. She discusses the inner workings and reason for the news and information source.

She was interviewed by Suzanne Gougherty, director of MMTC Media and Telecom Brokers at the Multicultural Media, Telecom and Internet Council. MMTC commentaries appear regularly in Radio World, which welcomes other points of view on industry issues.

Suzanne Gougherty: Soon to be BIN’s first anniversary, I imagine it has been a super exciting year – being part of historical launch of the FIRST Radio News outlet dedicated to serving the Black community, please tell us a few of your top highlights?
Tanita Myers: The Black Information Network’s first anniversary is such a wonderful milestone. In fact, it’s historic. It is such a privilege to be part of a network whose mission is to inform my community on issues that affect us every day and to have our stories told by people who look just like me.

The Black Information Network came along at just the right time as America and the world was dealing with a racial reckoning. It always seemed as if the mainstream media would only report the negativity within the Black community, therefore providing viewers with a slanted perspective on the experiences within the Black community.

At the Black Information Network we get to dive in deeper to expose the roots of some of the disparities that have plagued our community; but more importantly we also have the opportunity to highlight the incredible strides, accomplishments and sheer ingenuity of what makes Black people an incredible part of the world’s fabric.

[Read: Coles Takes a Bold Step]

There have been many highlights this past year including our coverage of the historic election of Vice President Kamala Harris, BIN’s live coverage of the Derek Chauvin trial and of course the opportunity to pay homage to civil rights leaders who have helped paved the way for true progress for the African-American community.

I’m also proud of how BIN has covered international stories such as the fighting in Tigray region of Ethiopia, lack of COVID resources in Haiti and the strife of Black people around the world who have also started their own Black Lives Matter movements.

I beam with joy every day to lead an award-winning team of journalist who brings these stories to life, from our perspective in our voice.

Gougherty: You not only produce news content, you’re a host, along with an array of other responsibilities, how to you juggle day-to-day operations? And what takes priority?
Myers: Juggling day-to-day operations is easy because of the extraordinary talented team that surrounds me. They are all personally invested in making sure BIN highlights the most important stories that educate and inform our listeners. Our priority lies in finding and researching the stories about Black experiences — whether police brutality, systemic racism, oppressive laws, voting rights, opportunities for Blacks to prosper, build thriving communities and more. The old adage that “knowledge is power” is something we subscribe to.

Gougherty: When and how does your day start and end? How do you relax?
Myers: My day begins at 2:30 a.m. ET which allows me to prep for our first editorial pitch meeting at 3 a.m. ET. I also use that time to catch up on overnight emails and news to make sure we are always accurate in our reporting. The 3 a.m. pitch meeting is just one of several during the course of the day. During pitch/editorial our anchors and I discuss what stories should take priority for that day’s reporting and what angles are most relevant to the Black community. The last editorial of the day is at 7 p.m.; after which I spend a couple of hours catching up on emails and checking various wires. Somedays the news cycle moves pretty fast, so I like to make sure we’ve tapped all resources such as social media to ensure we are giving untold stories the exposure needed to invoke change or inspire our community to greatness.

Gougherty: That sounds like a busy, work-dominated schedule. Do you have time to relax or break away?
Myers: Wow, relaxation? What a great question. I really enjoy my job, so sometimes it’s hard for me to relax in the “traditional” sense. There is always news going on! With that being said, I do love to cook and listen to music, usually both as the same time. I’m a pescatarian/vegan, if that’s a real thing, so I love trying out new recipes while listening to some good music of all genres and tempos.

Gougherty: What do you feel are some of the most important issues that impact the Black community? And how do you and your team determine what content is given priority 
Myers: The most important issues affecting the Black community are varied, but usually boil down to the same buckets. Systemic racism, police brutality, economic and health disparities, creating generational wealth and education. Each is a priority and we try our best to make sure we cover the it all.

Gougherty: What were the steps you took to prepare your team for the Chauvin trail? Who was the lead reporter? Tell us about BIN’s live coverage on the ground in St. Paul?
Myers: The Chauvin trial was this generation’s “trial of the century.” We launched the Black Information Network a month after George Floyd’s murder, so we began investigating and reporting all aspects of the case from Day One. When it came time to prepare for the trial we made sure to encompass all facts so we could accurately inform our listeners of how we got to this point in this horrific crime. The Chauvin trial was more than just seeking justice for George Floyd’s murder, the Black community also saw this trial as an opportunity to gain justice for all the other cases of police brutality that were never prosecuted. Because of the magnitude of the trial, for the first time the Black Information Network went live with a daily wrap up special of the day’s court proceedings with legal analysis and reactions from civil rights leaders from around the country. Vanessa Tyler helmed our coverage with contributions from the whole entire staff to make sure we covered every angle of this story.

Gougherty: BIN is on many stations coast to coast, how is local news, weather coordinated and communicated to all the various platforms — from the iHeartRadio apps, smart TV, smart speakers, etc. and over the airwaves?
Myers: The Black Information Network is growing daily and we are absolutely excited to bring local coverage to each of those communities. We have a team of reporters who are dedicated to researching and telling the stories that impact residents in their neighborhoods. When curating the local segments, the Black Information Network homes in on state, city, municipal politics and laws that effect their everyday lives. We also make sure we provide resources that residents can use to benefit their quality of life and empower them to strengthen their communities to generate positive outcomes. We have a wonderful partnership with Total Traffic and Weather Network (TTWN) and they have a stellar team of reporters who accurately deliver traffic and weather updates to our markets.

Gougherty: Do you have a news assignment desk?
Myers: We definitely have an assignment desk, but our anchors are the real drivers of sourcing news content. Once our daily editorial meeting is completed, stories are assigned based on block type. We cover news, entertainment, sports, and money. We are also fortunate to air commentaries from Roland S. Martin and Mo Kelley that focus on the liberal perspective. Additionally, since Black folks are not monolithic, we are also air conservative commentaries from Black talk show host James T. Harris.

Gougherty: Can you tell us about feature stories? Especially the good news stories that happen often in Black communities that are often overlooked in mainstream media.
Myers: There are so many “good news” stories that are overlooked and I’m so glad that we get the opportunity to showcase the Black community in such a positive light. My hope is that sharing these types of stories with our audience will inspire others to greatness and let them know that they too can succeed or become a positive leader in their communities. We also have a feature called “That’s A Fact” — where we applaud the accomplishments of Black people throughout history and those who are making history today. It’s important for our audience to know how wonderfully talented Black people are and the positive innovating things we have contributed to the world at large.

[See More Interviews With Suzanne Gougherty]

Gougherty: How do you assess the end of a news cycle day?
Myers: Ha! The news never ends. We are a 24/7 news network and the word operates on the same clock — news never sleeps.

Gougherty: What experience and understanding of the news industry did you have before joining BIN and how did it assist with the launch of BIN?
Myers: I’ve worked in traditional newsrooms before, but I think the most relevant experience of my career was the 16 years I spent with Tom Joyner. I’m originally from Phoenix, Ariz., and when growing up the Black population was below 10% so there weren’t very many opportunities to learn about our history — just the basics that was taught in school books.

I always tell people that my HBCU is Tom Joyner University. While there I learned so much about who we are as Black people, our history, and the importance of pride in all we do. He also taught me the importance of telling our stories and being unapologetically Black. Tom values education, civil rights, economic empowerment and closing the gap in our health disparities; these are the lessons I take with me every day into the BIN newsroom. I will be forever grateful for the life and broadcast “pearls of wisdom” I learned from The Fly Jock. Without the TJMS experience, I’m not too sure I would have been able to help guide this network into its true purpose of telling our stories, in our voice, from our perspective.

FM Translators for AMs Are a Double-Edged Sword

Radio World
3 years 10 months ago
Much of South Dakota looks like this stretch of I-90, visible straight all the way to the horizon. The author’s FM translator can’t be heard in cars beyond about 15 miles. Photo: Getty Images/Mike Kline

The author is a consulting engineer and station owner.

I’ve been in the broadcast engineering field since 1963, since the days of microphonic 6J7s in audio consoles thumping on the air to the announcers tapping the beat with his fingers, and changing coupling capacitors in ITC cart cue decoders three or four times in the same machines — you know, too long.

Well, in 1985, thanks to the Docket 8090 ruling, I happened to find an FM frequency that fell smack at my home in the woods on a mountaintop, in a community with no radio stations.

I had the frequency dropped in and applied, along with half of the East Coast. After four long years, I was awarded a CP, and my wife and I put on our very own station.

[Read More Guest Commentaries Here]

In spite of my limited knowledge of actually operating a station with programming, money, sponsors, money, insurance, money and just plain money, the station was quite successful even though we were the new guys in a market of 40 stations.

It was a lot of fun until deregulation, when the money guys bought up all of the stations they could and went for the throat of the successful stations, of which we were one.

A mom-and-pop operation is hard-pressed to go head to head with guys who give away $1,000 a day to listeners and have a sales staff of 20 cutthroat sales people, while we had three who were “nice guys.”

So my wife and I opted out and sold the station for a lowball figure just to be able to pay off the bank and get away from it.

I remember sitting in a burger joint after the closing saying to my wife, “I will never ever own another radio station again.” So I kept on with contract engineering a bunch of other stations; and all was well.

Can’t Say No
Over the years, we relocated a few times, and I wound up in northern Iowa doing engineering for a smaller group, taking care of 23 stations.

Although it was a decent job with decent pay, I was pushing 70, and years of traveling a thousand mile a week got to me. So I partially retired, keeping only the stations within an hour or two ride from home.

Then it happened. A broker had a small AM station in a small town for sale. Wow, it was a standalone AM. I love AM for the engineering opportunities and as an avid ham. It was a directional AM, even more fun.

The whole thing without a studio was on 15 acres of farmland, great. And most of all, the price was slightly more than a Ford F-150.

Wow, how could I go wrong? “If it flops, I can sell the farmland, cut the towers down and sell off the scrap iron and the equipment, and get my money back. Not only that, but it has an FM translator! Best of all worlds. This will be fun.”

At least that’s what I told my wife, who pointed out, “You said you would never own another radio station.” Well, I couldn’t pass it up.

Now, after operating for a few months, let me say that I wish the FM translator never existed. Single-handedly it has been the thorn to our total success.

 

Perception Is Reality
Why, you may ask?

Here we are in the middle of South Dakota, where the earth is solid sodium. The dry ground is white, the drinking water has got 530 mg per liter of sodium in it, but the ground conductivity is 30, best in the entire U.S. of A.

So this little 500-watter can be heard easily on the worst car radio 100 miles in just about every direction. The 2 mV/m contour in the lobe goes into North Dakota, about 90 miles away.

Okay, so much for this little screamer, now the FM. It’s a 250-watter at the same location as the AM. No mountains in eastern South Dakota, so it’s sitting on the prairie.

Most automobile radios can hear it 15 miles — then it’s gone.

Big deal, you say, what did you expect?

Well, most of the business people in the small town want to attract business from the other small towns around. Everyone in this town already buys from them.

So the business owner drives out of town with his car radio on FM and loses the signal before he gets out of sight of the town water tower.

To which he says, “I won’t advertise on your station, I can’t even hear it at my house 15 miles away, your coverage map lies.”

He neglects to check AM and discover that at 20 miles the whip on his car is glowing cherry red from the AM RF. So we don’t get a buy.

In other words, I would rather take my chances with 25% of the people who listen to the FM going to the AM and carrying it for 100 miles than giving the FM listeners the idea we peter out at 15 miles and never try AM.

I know it’s a different story in places like Pennsylvania, New York, Wisconsin and the like, where you can put the FM on a mountaintop and the ground conductivity is 1, so you can have a 250-watt FM that blows a 5 kW AM out of the water. But it ain’t so here.

I think my AM revitalization will involve pulling the plug on the FM and not offering the choice.

I see a lot of small-town AMs that succeed. From the service we give the town we will, but it won’t be from the business people in our city of license, it will be the people 50 miles out who never knew about the FM.

Workbench: How About Some PM for This AM?

Radio World
3 years 10 months ago
Checking the turns-counter on the phasor. Write down the indications for each control before you begin your work.

If you maintain an AM directional, why not put the summer sunshine to good use and perform a little preventive maintenance (PM)?

With your transmitter off the air and the breakers and interlock in place to prevent re-energizing, use a strong LED flashlight to view the variable coil and capacitor couplings from the back of the phasor. Remember before you begin to copy down all the turns-counter indications for each control as shown in the photo.

Then while your assistant rocks the component crank from side to side, check to make sure the couplings are tight so the variable coil or capacitor rotates smoothly.

I can’t tell you how many phasors our crew was called in to readjust because the setscrews holding the crank coupling to the component had become loose, so even though the engineer had turned the crank, one turn only adjusted the component by a half or even a third of a turn.

[Check Out More of Workbench Here]

In such a case, you can see how quickly you can get a phasor mistuned. When these setscrews are loose, there’s no consistency in how much the component is adjusted as the crank is turned.

The process isn’t a time hog and may save you hours of readjustment. While you’re inside the phasor, tighten all other strap and tubing connections.

 

Oops!
In the May 8 Workbench, I referred to selecting tower electrical connections “metrically.” Tom Weber, a principal in Weber Broadcast Services out of Greenwood, Ind., points out that I should have written “decimally,” as in tenths of an inch.

He’s right; metrically would assume millimeters or centimeters, which we are not using. We are converting inches to a decimal equivalent!

Tom concluded his note, “Yours in pedantry.” The sign of a great engineer!

 

Parts Is Parts
If you’ve recently needed to buy any broadcast gear, or for that matter any electronics, you may have encountered delivery delays caused by a parts shortage. The worldwide situation is causing problems for a lot of suppliers, so keep that in mind as you plan late summer or fall projects.

To complicate things, Workbench contributors Paul Sagi and Charles “Buc” Fitch, P.E., both reminded us of a related problem: counterfeit parts, including circuit breakers.

Shown, a Square-D QO circuit breaker. Counterfeiting of CBs is a real problem; manufacturers like Schneider Electric have tried to raise awareness of the issue.

For example Square-D, part of Schneider Electric, which is headquartered in France, makes Homeline and QO circuit breakers in Mexico; but for various reasons the opportunity for counterfeiting such material is immense.

Also be aware that used and harvested circuit breakers, especially larger, more expensive ones above 60 amps, are out there in the marketplace. Most of these were rejected because of trip problems; they may be touched up cosmetically, perhaps with new lug screws to remove tooling marks, and then sold as new.

The problem extends all the way through replacement parts in a variety of industries. In the communications business, RF transistors are especially subject to international counterfeiters.

Paul and Buc have both seen reports of numbers being stripped from similar solid-state device packages. Unfortunately these look-alikes are of insufficient capability and do not meet the high-performance specs of the number now imprinted on the device. The cheaper chips are then sold at a premium price, realizing profits of 400% or more. Profits can be even higher if the substitute device is not even an RF transistor or a “pull” or dud, none of which will meet spec.

Many entities cooperate in these crimes and profit from them. Because so much manufacturing is now done outside of North America, the provenance of parts can be very iffy. If the price looks too good to be true, it probably is. Save yourself the frustration and buy your parts from reputable dealers.

Here are helpful resources on the counterfeiting of circuit breakers. At www.ecpowersystems.com/resources/circuit-breaker, scroll down to “How to spot fake circuit breakers.” Or Google “Identifying Counterfeit Square-D Circuit Breakers” and look for the result that points to www.lanl.gov.

Last, Schneider Electric has a page dedicated to awareness and action against counterfeits. “We take counterfeiting of our products seriously and pursue every means possible to stop this illegal activity while making the industry and public more aware of this critical safety concern,” it states. See www.se.com/us/en/work/support/counterfeit.

 

Poof! Soundproofing!
In his engineering career, Dan Slentz has used a variety of soundproofing materials in constructing studios. But he laments that many products have gotten very expensive, forcing him to search for alternatives to keep within a budget.

One option is common mineral wool insulation, the properties of which allow for excellent sound blocking in walls, more so than fiberglass.

For studios, Dan has built double walls that do not touch but have a foam board between them. He then places mineral wool in each 2 x 4 wall. He completes the job with double sheetrock on the outside.

This can be a bear to construct, but short of bringing in a pro “acoustician,” it is a functional poor-man’s construction.

Dan has also used Troy Board (which was named after the inventor’s second son). It’s like a “shredded-wheat” board material but it’s really heavy. It can be painted, and it’s meant to block audio transfer. Check out https://troyacoustics.com/applications/broadcast-recording.

If you’re looking for the cheapest acoustic foam, try the Foam Factory. While its prices have increased lately, they tend to be less than those of similar products. They also vacuum-suck their product before shipping, so the packages arrive very small; the instant you cut it open, Poof!, it opens up and decompresses, taking about a day to recover fully.
