Tornado Wrecks Dallas’ KNON

Radio World
5 years 9 months ago

Those tornados Sunday night in Dallas sent KNON(FM) dark after a direct hit on the building housing the radio station’s studios.

Dave Chaos, station manager for KNON, was at home enjoying the Dallas Cowboys football game on TV when his radio station was literally blown away by the tornado.

“Great game but it was a horrible storm. I had a call at home that we had lost power at the radio station about an hour prior. Then the tornado hit the building and about all was lost,” Chaos says.

[Read: Months After Hurricane, WTJX Fights On]

The office building housing the radio station in North Dallas suffered major damage, including blown out windows. In addition, part of the building’s roof was blown off. Serious damage was done to the station’s main studio and offices, Chaos said. Some of the station’s broadcast equipment was damaged by the estimated 140 mph winds and broken glass and likely won’t be salvageable.

“We had several employees at the radio station when the tornado hit. They hid in the bathroom as the tornado roared past and shook the building. It scared them but they were uninjured,” he said.

KNON returned to the air less than 36 hours after the tornado, Chaos said, and continues to broadcast from a small brick building located at its transmitter site, which is located in Cedar Hill, approximately 20 miles southwest of its former studios. The transmission site remained intact following the storm.

“We are broadcasting at full power from an empty transmitter room and plugged straight to the transmitter. It’s about a 10 x 10 room. We have a few tables with a 16-channel Behringer mixer board, two CD players and two mics,” Chaos said. “We also have a USB connection into the board so we can plug laptops in with music to play.”

Chaos says the station will have to find a new permanent home since the damage to the station’s building is so severe. “We’ve already been told by the owners of the building we will not be able to rebuild there.”

KNON, which is owned by Agape Broadcasting Foundation, broadcasts at 89.3 MHz and also streams online. It plays jazz, punk, metal, gospel, R&B, Latin, blues, country, Cajun, reggae and Native American music, according to its website.

The radio station is a “nonprofit, listener-supported community radio station, which derives its main source of income from on-air pledge drives and from underwriting or sponsorships by local small businesses.”

The National Weather Service confirmed this week that a total of nine tornados hit the Dallas-Fort Worth area last Sunday night. The strongest twister, rated as an EF-3 by the weather service, packed 140-mph winds. No one was killed by the tornados and no major injuries were reported.

Radio Industry Remembers Engineer Gary Lee Ellingson

Radio World
5 years 9 months ago

The radio industry is mourning the death of long-time engineer Gary Lee Ellingson of Moorhead, Minn., who passed away on Oct. 11. He was 67.

According to an obituary on Inforum and the West Funeral Home in West Fargo, N.D., Ellingson was born to Oscar and Olga Ellingson of Thief River Falls, Minn., 24 years after the birth of his sister Helen. He was the youngest of four siblings, including Helen, Harry and Orville.

His father passed away after Ellingson turned two years old, and he and his mother regularly attended the Evangelical Free Church in Thief River Falls.

While working at a local radio station in the 1960s, Ellingson made a life-long commitment to religion and long talked about the correlation between current events and scripture. He pursued a career in missionary radio after attending Moody Bible Institute in Chicago in the fall of 1972. It was there that he met his wife, Billie Sue Shreve, and the two were married June 4, 1976, in Circleville, Ohio.

Ellingson went on to finish his college education at Northland Community College in Thief River Falls, including two years of electronics study at the Area Vocational Technical Institute, followed by Grace College of the Bible in Omaha, Neb.

While attending Grace, Ellingson worked full time as chief engineer for KGBI and KROA, two Grace radio ministries in Omaha and Grand Island, Neb. It was during that time that Ellingson developed a method of correcting interference between an antenna and the tower upon which it is mounted and distributing the mechanical load on the tower while allowing the antenna to be rotated around the tower. Through a friend in his Greek class at Grace, Ellingson was introduced to Wendell Miller, a registered professional mechanical engineer and patent agent in Goshen, Ind. Gary’s invention resulted in four United States Patents with the systems still being manufactured today.

Ellingson also worked for Motorola as a field service technician and then took a job as dispatcher-jailer at the newly constructed Law Enforcement Center in Thief River Falls where he installed all of the radio equipment.

Ellingson and Billie Sue moved back to Thief River Falls with their first two children, Daniel and Andrew, and he continued working in broadcast engineering as a field service engineer, and eventually went full time in manufacturing the antenna positioning system. He and a number of friends and relatives pooled resources to complete the patent process and went on to form Polar Research Inc.

The couple, with arrival of a third child, Mathew, moved to Moorhead, Minn., where Ellingson took a job teaching electronics at Moorhead Area Vocational-Technical School and he added a part-time announcer job at KFNW radio in Fargo. Their daughter, Kristin, was born shortly after moving to Moorhead.

In addition, he served as a pastor at New Hope Evangelical Free Church in Moorhead and went on to become director of engineering for the University of Northwestern in St. Paul, Minn., a missionary and liberal arts university.

Ellingson is survived by his children Daniel (Alissa) from Woodbury, Minn; Andrew (Krystyna) from Thief River Falls, Minn.; Matthew (Maria) from Minnetonka, Minn.; and Kristin from North Dakota. He is also survived by nine grandchildren: Samuel and Abigail from Woodbury; Gweneth, Logan, Farrah and Natalie from Thief River Falls; and Layla, Penny and Gloria from Minnetonka. He was preceded in death by his parents Oscar and Olga; his siblings Harry, Orville, and Helen (Adamson); and his wife Billie Sue, who passed away Dec. 1, 2018.

At Ellingson’s request, in lieu of gifts or flowers, please consider giving the equivalent amount to Ravi Zacharias International Ministries, 3755 Mansell Road, Alpharetta, Ga., 30022 or Bethel Church, 2702 30th Avenue South, Fargo, N.D., 58103.

Visitation will be held at West Funeral Home, West Fargo, N.D., on Oct. 23, with the funeral held at 11 a.m. on Thursday, Oct. 24, at Bethel Church in Fargo, N.D. Burial will be at Sunset Memorial Gardens in Fargo.

Is the FCC Dropping the Ball on Directional Translators?

Radio World
5 years 9 months ago

Larry Langford is the owner of WGTO(AM) Cassopolis, Mich. and W246DV, South Bend, Ind. You can reach him at LarryLangford@aol.com.

The author is owner of WGTO(AM) and W246DV(FM), South Bend. Ind. He has been in radio since 1965. His commentaries on radio issues such as those facing AM owners are a recurring feature. Read his past articles by searching for “Langford.”

The job of a consulting engineer is to do everything possible to maximize the facilities of a client within the constraints of FCC regulations, the laws of physics and the budget of the applicant.

In the case of a full-power FM that needs a directional antenna system, the FCC demands strict conditions before the License to Cover application is granted. These include detailed paperwork from the applicant showing that the antenna was designed by a reputable manufacturer using a test range with full-size or modeled  antennas that take into account the tower design, other antennas mounted to the tower, cables, conduits and anything else that could cause pattern distortion. The commission wants to see sketches, notes, and test results from the maker of the antenna.

[Read: Chicago Translator Concerns]

They further require you to use a licensed  surveyor to certify that the antenna was mounted at the correct azimuth as called for by the manufacturer and, lastly, the commission requires an affidavit from a qualified engineer that everything was done by the book and the resulting pattern is good based on a proof of performance. All this can be required of the simplest of directional systems for full power FMs

With consultants now being asked to shoe-horn translators  into the tightest of places, we are seeing some rather curious antenna patterns in FX applications. Some stretch physics to the absolute limit!

Again, understand, just because the consultant can specify a complex contour, one that requires a composite antenna design, it does not mean that the antenna company can make it happen for less than a king’s ransom. What is shocking is that for translator directionals, the FCC demands only a checkbox that promises that the antenna meets the required contours as shown in the CP. Talk about faith and trust. I will admit that for some “off the shelf” directionals and omnidirectional antennas that are side-mounted with a predictable pattern, just the antenna sheet and a promise that it was put up pointing the correct direction is probably enough.

But let’s take the case of the antenna pattern granted on a Chicago translator that is a real head scratcher!

Figure 1

Figure 1 shows a pattern that is obviously protecting more than three co-channel translators and full power FM stations. These pretzel patterns are becoming more and more common in metro areas where FX openings are tight. In this case the CP application specifies a two-bay “penetrator” style antenna with parasitic elements to get this very  complex and nonsymmetrical  pattern in both the horizontal and vertical planes.

If this pattern can be done with this type antenna it would take a lot of range testing and a big box of parasitics installed with great precision and care to pull it off.

The price tag for that would be in the thousands. I have seen more than a few installations that demand such complex antennas that are simply built with an omnidirectional  and no attempt to follow the one-of-a-kind design in the application. The temptation to cheat here is just too great and the results are a mess when there is an interference complaint and the commission relies on these sometimes fantasy patterns to be accurate.

I cannot blame the consultants, they just show what needs to be done. And often the person signing the License to Cover application is simply one of the owners just checking the box with no idea as to what pattern they really have. There are other cases where the commission is just plain wrong via its own mistakes on issuing a license. I know of a Chicago area translator with a detailed application on how the system would take care of second adjacency interference by using a multibay antenna to attenuate downward signal. The details were part of a waiver request. But when they put in the License to Cover application they specified a single-bay omni. And guess what? The commission granted the license anyway. Obviously this one slipped through the cracks.

With AM it’s pretty easy to check on a directional antenna system, just drag out the Potomac and find the monitor points. But trying to do a field proof on a 250 W translator DA with a meter to check on an installation after the fact will drive you crazy and tell you very little.

The FCC must tighten up regulations to make sure these exotic patterns drawn to get a CP are in fact built to get the License to Cover.

Since the commission requires detailed proof that a directional was actually built and installed correctly for a commercial FM, why not at least some documentation that shows that a composite directional FX antenna for the requested CP was actually built and tested on a range with proper proof of performance?

The commission would never accept the “word” of an AM operator that his multitower array was good without paperwork, so why allow translators to be put in with these very difficult patterns on just a wink and a promise that there is no cheating? While some old and outdated rules are being tossed out, here is one that needs to be revised for more not less paperwork.

Groups Call on FCC to Waive First-Term Fees for Incubating AM/FM Stations

Radio World
5 years 9 months ago

Of all the hurdles that new entrants and small broadcasters face when it comes to accessing capital to set up a broadcast station, there’s one challenge in particular that the Federal Communications Commission shouldn’t overlook: The task of keeping up with additional financial obligations like annual regulatory fees.

According to two media groups, the commission needs to reconsider the heaviness of that burden as part of its Assessment and Collection of Regulatory Fees for Fiscal Year 2019 Report and Order and Further Notice of Proposed Rulemaking, which was released in August 2019. As part of that order and rulemaking, the commission is seeking comment on whether it should adopt a lower regulatory fee for full-service AM and FM broadcast radio station incubator licensees.

[Read: Groups Press FCC to Recommit to Promoting Media Diversity]

The answer is a resounding yes, according to two those two media organizations. In new comments filed with the commission, the Multicultural Media, Telecom and Internet Council and the National Association of Black Owned Broadcasters reiterated its stance that additional financial obligations, such as regulatory fees, may render it more difficult for incubated entities to thrive under the FCC’s incubator program as stations attempt to access capital and apply for new construction permits.

In comments filed back in August, the two groups proposed that the commission give an outright exemption to incubated stations for having to pay regulatory fees for a the initial eight-year term of the incubation period.

With a subsequent request in the R&O and FNPRM, the FCC asked for commenters to discuss a reduction that approximates, perhaps, as much as 50%.

That’s an amount that the MMTC and NABOB take issue with.

“[The commission ] is silent on the reason for an ‘appropriate reduction’ in the fee, and we cannot conceive of any reason why only a partial fee reduction would be justified,” the group said in its most recent filing. “In our experience, broadcasters generally need strong financial incentives to participate in FCC diversity initiatives. A waiver of all fees for a license period would profoundly demonstrate the commission’s endorsement of incubation and create a powerful incentive for it.”

While the dollar amounts of regulatory fees for an eight-year license term are “meaningful,” the two said, they are not so large as to materially diminish the commission’s ability to fund its operations. As a result, the two groups are pressing the commission to adopt the MMTC/NABOB proposal as filed.

Comments on the issue of regulatory fees can be viewed at the FCC’s ECFS database using Docket Number 19-105.

What Does a Broadcast Engineer Do, Anyway?

Radio World
5 years 9 months ago
The image of today’s broadcast engineer is a lot different than that of days gone by.

I was thinking the other day about what a broadcast engineer does. For the first couple of decades of my career, that was a fairly narrow list: Maintain and repair studio and transmitter equipment. Build out a studio or transmitter facility. Maybe fix the plumbing or install a radio in the GM’s car.

But at some point, things began to change. Personal computers began to enter the broadcast infrastructure. Then networks and file servers began to appear, and we had to add new skills. At the same time, staples such as turntables, cart machines and reel tape recorders began to disappear. As the years slid by, even CD players began to fade from the scene.

In a way, this paralleled changes in the auto service industry. Mechanics who for decades wore greasy coveralls and worked on carburetors, distributors and water pumps traded their coveralls for more professional attire, went from oil- and grease-stained hands to blue nitrile gloves and became technicians rather than mechanics. As with broadcast engineers, a whole new skill set was needed, one that included computers, sensors and OBD ports.

PORTS AND PASSWORDS

As I look around my company and consider the top-shelf group of engineers that we employ, I realize that their primary skills are in the IT domain.

We recently had one northern market CE leave for warmer climes, and as his newly-hired replacement came in and began work, the challenge was not transmitters, processors and antenna systems, but rather networks, IP addresses, ports and passwords. Because of the IP-heavy infrastructure, Job No. 1 had to be learning the networks at the studios, offices and transmitter sites and figuring out how it all works.

In the earliest days of my career, I worked at a local FM station (which few people listened to because there were few FM radios out there) changing automation tapes and doing top-of-the-hour rip-and-read news. The chief engineer was a guy named Don Freestone, and my memory is of him hunched over a smoking soldering iron back in his engineering shop, which was next to the AM transmitter room. That was pretty much the image and stereotype of the broadcast engineer for a long time. Back in the day, I even saw an episode of “WKRP in Cincinnati” with a brief glimpse of a broadcast engineer with that same stereotype.

Today, the image is a little different. Today, it is the engineer, probably dressed in khakis and a polo, sitting (or standing) at a desk hunched over a laptop computer, fingers flying over the keys as mysterious characters scroll by on the screen. That image is not far off. In this company at least, that is where our engineers spend most of their time, not making wiring changes or repairing equipment.

In today’s IT-centric broadcast plant, “wiring changes” are done with a mouse, making and breaking crosspoints in software. Even transmitter remote control systems are configured in software, using SNMP and Ethernet cables rather than the fat multi-conductor control cables that we used for that purpose for decades.

With the changes in infrastructure have come big changes in the ways we as broadcast technical professionals do business, and as I mentioned, the skill set has changed. For young upstarts, this is no big deal; IT is their native language; for old guys like me, well, we have a lot to learn.

TALL ORDER

So what does that mean for broadcast engineering as a field?

For starters, it means that the job description has to change, and because of that, our recruitment sources also have to change. Do we seek out and hire RF and audio people and train them in IT, or do we hire IT people and train them in audio and RF?

Either path, on the surface, is valid, but out here in the real world, it’s a tall order to find RF and audio people, especially young people just entering the workforce that have any training and expertise in audio and RF. It’s much easier to find young college or trade school grads who are trained in IT.

The practical course of action, then, is to find upstart IT people and train them in the other aspects of the broadcast engineering trade. Easy, right? Maybe not. There are a number of challenges to this course of action.

First, the career path model, while we weren’t looking, has changed dramatically. No longer are young people content to work and learn under a more experienced “guru” and then move up the ladder over a period of years as their skills develop. Those skills are in such demand that upstarts hit the ground running, landing high-paying jobs right out of school. They often move from job to job every year or two, always getting a better deal and a bigger paycheck.

Except for purely IT people, the broadcast industry cannot compete with that, not really. What we offer is a slow rise up the ladder that includes a lot of learning of other skills that are really well outside of the wheelhouses of IT-trained people.

And of course we offer lower pay and lousy hours. Why on earth would any young upstart trained in IT want to subject herself to that if she could easily land a job at Verizon or T-Mobile that pays more, has better benefits and regular hours?

So therein lies the challenge. It would seem to be nearly impossible. And yet … and yet … I have managed to find and hire a number of superb youngsters, real rock stars, over the past few years who have taken to the broadcast engineering trade like a fish to water.

Yes, they love their ones and zeros. They love their obscure command line syntax and code.

But they also love radio. And they have come to love transmitters, transmission lines, antennas, audio processing and sound just as much. It has been a real pleasure watching these youngsters bloom into what will be tomorrow’s chief engineers and engineering managers.

I might add that it hasn’t hurt one bit that our audio infrastructure has moved into the realm of ones and zeros (AoIP), or that transmitters, remote controls, audio processors and even STLs now have IP addresses and communicate with users in the IT domain.

The question, then, is how do we find such people? That’s a tough question, and I don’t have an easy answer. The best I can tell you is to be on the lookout for youngsters who might have the knack for radio.

Job fairs are often a good place to look. IT folks attend job fairs looking for employment, and maybe they are drawn to the banner with the radio station’s call sign because they listen to or have heard of the station, and they’re intrigued. Could it be that this radio station has a job for me that could be something more than assigning IP addresses and creating subnets?

At some point as you talk to them, the inevitable question is asked: “What does a broadcast engineer do, anyway?” The answer: “We do it all.”

And the one thing you can promise is that they’ll never get bored. Let Verizon or T-Mobile compete with that!

What Exactly Happened to Ampegon?

Radio World
5 years 9 months ago

The author is sales and business development manager for Ampegon Power Electronics AG.

TURGI, Switzerland—Following this year’s IBC exhibition in Amsterdam in September it became clear that, despite our best efforts, many in the radio community are still in the dark about what has recently happened at Ampegon; a long-term supplier of transmitters and equipment to shortwave and medium-wave broadcasters worldwide.

Simon Keens

Rumors have abounded regarding the health of the company and we hope today to clarify the situation here

Late in 2018, Ampegon’s former investment capital owners decided to sell Ampegon. This had been planned since 2012 when they acquired the company following the restructuring of the Thomson group. Since you never completely fuel a car that you’re just about to sell, Ampegon was instructed to minimize further unnecessary investment in marketing, which is why customer visits and conference attendance fell to a historic low. This left the company to focus solely on completing projects prior to transfer of ownership.

In the end, the process of selling the company took longer than anticipated, meaning that some projects were delayed and left unfinished at the point of sale. Additionally, the former owners proceeded to sell the four parts of Ampegon separately: The shortwave transmitter, power supply and control system section in Switzerland, the antenna division in Ludwigshafen, the former Transradio medium-wave transmitter factory based in Berlin, and the industrial pulsed power supply specialists in Dortmund, all in Germany. This necessitated a break-up of the group, with assets from each company being sold off individually. It inevitably caused disruption to normal operations.

The shortwave transmitter business, along with the staff, tools, and stock material has now been bought by a new Swiss company: Ampegon Power Electronics AG. This company was formed specifically to complete the transaction with Ampegon AG, and took over all IP and technology rights, branding (including the name and logo of Ampegon), website and contact details.

Telephone numbers and email addresses for contacts in sales, engineering and purchasing are essentially unchanged. Today (at time of writing) we understand that Ampegon AG exists only as a company on paper, with practically all staff moved over to Ampegon Power Electronics AG. Similarly, staff and assets from Ampegon Antenna Systems GmbH and AM Broadcast GmbH have been sold to Cestron International and now continue their respective businesses under the name Elsyscom.

We hope that Ampegon Power Electronics and Cestron/Elsyscom work closely moving forward, once the necessary agreements are in place; providing the integrated transmitter/antenna systems that have been so successful in the past. Research Instruments has acquired the industrial pulsed power team in Dortmund, although this is not considered significant to the broadcast community.

Unfortunately, a number of Ampegon’s customers were left with partially completed projects when our former owners withdrew their support in preparation for selling the company.

The company’s former staff — who remained in post even though they went unpaid for some months — regret the inconvenience caused, but are currently working hard under Ampegon Power Electronics to resolve the issues arising from being a new company, and not the legal successor of Ampegon AG. This has meant that contracts must be transf

erred, warranties reviewed and all other previous agreements with our customers and colleagues in the community must be annulled and renewed.

Looking ahead, however, the core skills of Ampegon remain in place to support the broadcast community over the coming years and decades. By and large Ampegon’s engineers and employees are the same people in the same place doing the same thing, but now with an industrial group behind them rather than a capital investment company. We are looking forward to continuing work with our friends and colleagues in the community as we look at new revolutions in broadcasting such as Digital Radio Mondiale, data communications and energy efficiency in the future.

Development of Ampegon’s second-generation Class A/B solid-state transmitters is practically complete, with production of 1.5 kW – 25 kW versions, capable of broadcasting between 3 MHz to 30 MHz, ramping up. A third-generation solution offering significantly greater energy efficiency is approaching prototype stage.

[Read: Solving the Medium-Wave Problem]

Simultaneously, Ampegon has developed control system upgrades to support users of older-generation tube transmitters having difficulty sourcing spares, and also to provide opportunities to retrofit older systems with new digital DRM broadcast capabilities. Of course, with touchscreen technology and innovative controls, such an upgrade makes these transmitters easier to use, simpler to maintain and safer than ever before. Of course, we are complimented by the requests to support over 20-year-old transmitters, since this is testimony to their reliability and value.

It is Ampegon’s hope to continue serving shortwave broadcasting long into the future. We see the unique capabilities of the technique, and the significant future opportunities presented by digital broadcasting with DRM. And who knows what other technologies may benefit from use of shortwave? Time will tell, and Ampegon intends to be there to support it.

NYSBA Honors Native Son O’Rielly as New Yorker of the Year

Radio World
5 years 9 months ago

As he gratefully accepted an award from New York State Broadcasters Association, Federal Communications Commissioner Michael O’Rielly noted — wryly — the irony of the moment.

The award, for New Yorker of the Year, was being bestowed, he said, on a government bureaucrat “who never spent one day working at a broadcast station; who has never been closer to the news industry than when he had a paper route.” Those were some of the remarks made by O’Rielly — undoubtedly to laughs from the room full of broadcasters — during a luncheon with the NYSBA during its Broadcast Leadership and Hall Of Fame Luncheon on Oct. 17 in New York City.

[Read: O’Rielly: First Amendment Rights Worthy of Strongest Defenses]

“You should know that, when David [Donovan, president of NYSBA] called to congratulate me for being selected as New York Broadcasters New Yorker of the Year, I suggested he was way off base,” O’Rielly told the crowd. “In my mind, I stand before you as someone completely unworthy of this honor. Let’s face it: you are looking at a short, overweight, government bureaucrat … whose claim to FCC fame includes successfully allowing broadcast stations to close up shop,” (albeit, he said, as part of the much-lauded elimination of the FCC’s long-standing Main Studio Rule).

“[While] there are far more deserving individuals from this amazing state,” he said. “But…not being on the selection committee myself, I happily accept this award.”

O’Rielly, a native New Yorker from the western part of the state, said broadcasting provided a “wonderful foundation of fulsome life experiences” that have been enormously valuable throughout his professional career. He was born and raised in a small city on the Erie Canal just outside Buffalo, N.Y., which is home to hearty, hardworking individuals that — as he said in his confirmation hearing back in 2013 — “accept the hard winter weather and lack of sun as a badge of honor.” All across the State of New York, O’Rielly said, people are smart, gritty realists who tend to tell it as it is. “Throw into that mix some challenging weather from time to time, and you have the formula for some really unique individuals that tend to do well in our fairly complex society,” he said.

Local broadcasting was a key part of his early education, he said, as local news, sports coverage and children’s programming fed some of his earliest interests. During his six-year-long tenure at the commission, O’Rielly said he has attempted to distinguish himself as someone who listens attentively to the problems and issues facing broadcasters and tries to find workable solutions, from local ones pirate radio to broader ones like the seismic shift in the video marketplace.

“Part of my focus has been to reduce the overall regulatory burden on broadcasters, as is demanded by the FCC,” he said. “This means eliminating any and all unnecessary requirements that impinge on broadcasters’ ability to serve their local communities. Your government should not mandate obligations that impose undue costs and require inordinate time to comply when a regulation has far outlived its usefulness in the modern marketplace.”

O’Rielly told the organization that the good news for the broadcast industry is that there are important and vibrant opportunities ahead. “While the competitive marketplace may change around you and technology may continue to present challenges, you provide real value to the American public,” he said.

For local radio in particular, “your role in the community has never been more important, especially with the demise of so many newspapers.”

He touched on personal tragedy during the event by saying that a recent death in his family of his brother-in-law put a somber note on his appearance at the event.

But he closed by saying that this award would only serve to make him “work harder, smarter and longer to ensure that the American people are getting their money’s worth from the FCC.”

As president of the NYSBA, Donovan said that O’Rielly stands apart as one of the outstanding commissioners in the history of the FCC.  “He studies an issue in depth and then makes a principled decision,” Donovan said, saying O’Rielly has been a leader on a number of issues affecting New York broadcasters, including his championing of increased enforcement against illegal pirate radio operations.

Prior to being nominated by Pres. Barack Obama in 2013, O’Rielly served in key positions in the U.S. Senate, including as policy advisor in the Office of the Senate Republican Whip and as a professional staff member on the Committee on Energy and Commerce for the House.

PBC Tests DRM for FM on a Consumer Receiver

Radio World
5 years 9 months ago

On Oct. 17 Pakistan Broadcasting Corp. began DRM for FM test transmissions on a consumer receiver.

According to the DRM consortium, the public broadcaster is sending the DRM signal from its headquarters in Islamabad using a low power of 75 W. The signal reportedly reaches an area of between 5–10 kilometers around the city.

Pictured from left to right are Ghulam Mujaddid (PBC), Roman Afroz (HEDRA), Peter Timmons (GatesAir), Kamran Saeed and Nauman Jarral (PBC).

Broadcasting on 101.6 MHz and pushing from a single FM transmitter, the receiver auto tunes into three services — FM101 (entertainment), Dhanak (music) and Saut-ul-quran (religious). Additional text information including Journaline is also available.

For the trial, the PBC is using a GatesAir 1 kW Flexiva transmitter and Exgine card; an RF Mondial DRM Content Server and DRM+ professional receiver; a Label Italy Bay antenna system; and a Gospell consumer DRM receiver.

“The Gospell receiver, which originally worked on AM is now working on FM too,” noted DRM Chair Ruxandra Obreja. “This is a great step forward as it shows there can also be a commercial solution for DRM in FM. A similar test, which started this summer and continues in St. Petersburg, Russia, is also using a Gospell receiver.”

Hedra Technology, Fraunhofer IIS and the DRM international Consortium are collaborating on the project, which is managed by PBC specialists Kamran Saeed, director engineering; Ali Zia Abbasi, controller engineering and chairman DRM steering committee; Ghulam Mujaddid, engineering manager and DRM steering committee member; and Yasir Mustafa, engineering manager and DRM steering committee member.

DRM adds that in addition to Russia, Pakistan joins Indonesia and South Africa. Both of these countries have recently demonstrated DRM in the FM band as well.

DABCAST Designed to Simplify DAB+ Implementation

Radio World
5 years 9 months ago

Technical broadcast operator BCAST has debuted a new platform that is meant to help small and medium broadcasters implement the DAB+ standard, named DABCAST.

DABCAST supports the range of functionalities needed for digital radio creation from studio to broadcasting. This is done through its Virtual Studio web app, where multimedia content can be created and managed.

The cloud application MUX processes the radio streams and converts them into the appropriate format for DAB+; while the TX transmitter, a physical device that receives signal from the cloud, modulates it for final broadcast. The signal from the air is then analyzed by the DAB+ monitoring probe.

More information about DABCAST can be found here.

Best of Show Up Close: Broadcast Partners Smart Processing

Radio World
5 years 9 months ago

“Best of Show Up Close” is a series about participants in Radio World’s annual Best of Show at NAB Awards program.

Broadcast Partners nominated Smart Processing, a module of the company’s Smart Radio. SmartRadio is a cloud-based radio automation platform. We asked Rene van de Kolk, manager, R&D, Broadcast Partners, to explain.

Radio World: Smart Processing was a feature of your booth at NAB. For those who couldn’t attend, what is the product and what are its targeted uses?

Rene van de Kolk: Smart Processing provides three different cloud-based modulation-processing solutions: Basic, Medium and High-End. Smart Processing uses Orban back-end software solutions for this.

Smart Processing is a part of Broadcast Partners’ SmartRadio platform, and can be used in this full cloud- and web-based platform by integrating with the Smart Playout possibilities by using AoIP protocols. Smart Processing is hybrid, and thus also standalone, available outside the SmartRadio platform and can easily be connected with other existing playout services.

[Read: Best of Show Up Close: MaxxKonnect Wireless]

Smart Processing delivers excellent Orban modulation presets and a unique sound, with all of the presets that Orban has been offering the market or years.

Smart Processing is for the increasing online and digital radio market. Media companies all over the world are launching multiple subchannels as additions to their main brand. These can be for shorter periods or select certain seasonal theme such as summer, Christmas or Valentine’s Day or used for longer periods. Branded radio channels can be launched easily without investing in hardware units or upgrading server farms. So targeted users are media companies, radio stations and publishers who launch multiple online or digital (DAB+) radio stations.

RW: You describe SmartRadio as “radio as a service.” How does it differ from other offerings in this product class?

Van de Kolk: SmartRadio is 100% cloud- and web-based. All functionality can be used in a Chrome browser. Creating and producing content can be done easily, anywhere, anytime or any place. The only requirement is connectivity. SmartRadio is a beginning-to-end solution: using Smart Database with multiple metadata options that can be used for playout, cloud-based voice tracking, cloud-based multitrack editing without delay and pushed through Smart Processing to be published on multiple platforms online or digital radio, for example.

For online, the best CDN network from the Netherlands is fully integrated. In addition, the specially developed headend for DAB+ services, aXemble, is as-a-service available in SmartRadio. With these services our goal is to help existing and new media-organisations to innovate without the need of heavy investment. All services are available as-a-service with specific pricing per module. For the past two years, we developed this platform with eight developers at Broadcast Partners.

At NAB, IBC, Salon de Radio and Radiodays Europe we retrieved feedback from the market to develop customized solutions. This is possible because all services (also a full Smart Scheduler, or Smart Commercial Scheduler) are developed by thinking in micro-services terms. This means hybrid and flexible development in the most modern program code-language. Connections with other innovative parties is possible by using our API. In SmartRadio, connections with VMix, Beats Newsportal and Radio Manager are already made.

RW: What does SmartRadio cost? Is it available now?

Van de Kolk: SmartRadio is fully hybrid and can be used in all preferred setups. Licenses can be used as-a-service per month/radio channel and are customizable for one channel for one month in an existing cloud environment. This includes the Smart Database (including cloud-and web-based metadata-editor), Smart-Format Scheduler and Smart Non Stop Player (including four-channel cloud- and web-based editor). SmartRadio is available in public cloud-based environments but can also be installed in private cloud-based environments. All preferred connections and add-ons for services will increase the monthly fee.

Smart Processing, is also available. Licensing/pricing is based on an as-a-service model. For one radio station you pay the required service fee per month based on your preferences.

RW: More generally, what do you see as the most important trends or changes happening these days in how broadcasters are using the cloud?

Van de Kolk: Using AoIP solutions from companies such as Lawo, Ravenna, Telos Alliance and Dante [Audinate] but also virtualized complete productions environments. That’s also why our software-defined solutions are integrated in the different mixing console platforms, to provide a full screen-based user-experience in the future. By publishing multichannel, on different platforms, hybrid software solutions are important and are more flexible in terms of updates than ever before in the past. Relevant data from listeners is key if you want to stay relevant in the future, so collecting data and receiving clear insights is also a main trend, in my opinion.

 RW: What else should we know about this product or your company’s recent offerings?

Van de Kolk: Different modules are available. Innovation can therefore be done in different projects or trajectories. Our Smart Scheduler, is a full option format planner and can be connected to all big existing solutions when they are able to connect on API. A very impressive web-based user-experience in defining your format is possible.

The Future Best of Show Awards program honors and helps promote outstanding new products exhibited at industry conventions like the spring NAB Show. Exhibitors pay a fee to enter; not all entries win. Watch for more coverage of participating products soon. To learn about all of the nominees and winners, read the 2019 Best of Show Program Guide.

EuroDAB Italia Begins Airing BBC World Service

Radio World
5 years 9 months ago
Eugenio Lateana, head of research and development for EuroDAB Italia (left); Federica Gentile, RTL 102.5 presenter (center); and Mary Hockaday, controller of BBC World Service English, announce the Italian launch of BBC World Service on the EuroDAB Italia multiplex.

MILAN — BBC World Service and EuroDAB Italia have entered into an agreement to broadcast the global network’s rich mix of BBC News, documentaries, business, sports, arts and science programs as a new service included in EuroDAB Italia’s DAB+ multiplex.

On Oct 9, Mary Hockaday, controller of BBC World Service English, and Lorenzo Suraci, president of EuroDAB Italia, officially launched the new service and presented the vision behind this agreement and their expectations for the future.

TRUSTED BRANDS

Mary Hockaday (left) and Lorenzo Suraci, EuroDAB Italia present, presented the vision behind the new agreement and their future expectations.

Although about 30% of Italians can speak some English, including a large part of the younger generation, no English-speaking service is at present broadcast in Italy on regular basis.

“We live in a world with an infinite number of information sources and making a choice among those sources often makes us feel confused,” Hockaday said. “It’s wonderful to have such a diversity, but in this surrounding noise actually many people seek trusted brands, and they seek media and information they can trust.”

According to Hockaday, trust is at the heart of what BBC and BBC World Service can offer, including “accurate and impartial means and good information.”

In a world where everyone can have on his or her smartphone a multitude of headlines and news from all over the world and from as many different sources, Hockaday emphasized how hard the BBC World Service works to provide their listeners with a rich editorial mix with news but also information on business, sports, culture, technology, politics and stories.

DIGITAL CAPABILITY

The BBC World Service logo displayed on a visual-capable DAB receiver tuned to the EuroDAB Italia multiplex.

“Whenever you turn on the radio, you will always find something engaging, informing, delighting and feeding curiosity within our offer ,” she concluded.

“We are very proud that BBC World Service choose the EuroDAB digital network to broadcast its content in Italy,” added Suraci. “It improves and extends the offer of the contents of our bouquet and helps the radio, in general, in an increasingly global world.”

DAB+ broadcasts are already available to 80% of Italians and that percentage is set to grow due to the Italian legislative requirement for all radios sold in Italy from Jan. 1 2020 to have digital capability.

[Read: Does 5G Make Sense for Radio?]

In Italy, 46% of new cars are now sold with DAB+ as standard, and according to the Italian media regulator AGCOM, radio is the second most frequently used media after television, while 68% of the population listens to radio for an average of 2.5 hours per day.

New FM Construction Permit Auction Set for April 2020

Radio World
5 years 9 months ago

A new round of construction permits are about to be up for auction.

The Media Bureau at the Federal Communications Commission introduced Auction 106, a new FM broadcast construction permit auction scheduled to commence on April 28, 2020.

Auction 106 will offer 130 construction permits for FM broadcast allotments, including 34 permits that were either defaulted upon or not sold or in earlier FCC auctions. The commission released a list of those vacant FM allotments, which include teeny Texas hamlets like Milano, Texas, population app. 400, as well as populous urban thoroughfares like Coalinga, Calif.

The bureau plans to follow the commission’s standard auction procedures — a multiple-round auction format that offers every construction permit bid at the same time and consists of successive bidding rounds in which qualified bidders can place bids on individual permits. Bidding usually remains open until bidding stops on all permits.

The auction will be conducted over the internet using the FCC auction bidding system, although bidders will also have the option of placing bids by phone. The bureau is also proposing to stop, slow or speed up the bidding if the process is proceeding at either a sluggish or a too rapid pace.

As in earlier auctions, the bureau proposes that applicants submit upfront payments as a prerequisite to becoming qualified to bid.

But before things kick off, the bureau and the Office of Economics and Analytics is seeking comment on a variety of auction-specific procedures relating to Auction 106 — including the proposed open bidding process, how much upfront payment should be required for each CP and the proposed opening bid amounts.

The price range for construction permits in Auction 106 vary wildly. On the low end sits permits for $750, such as ones in Wamsutter, Wy., and San Isidro, Texas. Compare that to the upfront payment of $100,000 — and the subsequent minimum opening bid of $100,000 — for a CP in California’s capital city of Sacramento. Mid-level bids include Huntington, Ore., for $45,000; West Rutland, Vt., for $25,000; and Gackle, N.D., for $15,000.

The initial bidding schedule will be announced one week before bidding starts via a public notice.

Comments on Auction 106 can be made through the FCC ECFS filing system using AU Docket No 19-290. The commission is also requesting that all comments be submitted electronically via the email auction106@fcc.gov.

FM broadcasters who have questions can reach out to the Audio Division within the Media Bureau at 1-202-418-2700.

Dosch to Devote Full-Time to Angry Audio

Radio World
5 years 9 months ago

Mike Dosch will be leaving his role with equipment manufacturer Lawo and focusing full-time on his recently launched company Angry Audio.

Separately, his new company also will acquire the StudioHub wiring infrastructure line.

Dosch joined Lawo in 2014 with the title of director of virtual radio projects and later was named senior product manager radio. Prior, he was president of the Axia Audio division of the Telos Alliance; for 10 years before that he was with Pacific Research & Engineering, where he started as a console designer and worked his way up to VP and COO.

His company Angry Audio makes small problem-solving devices that it happily refers to as “gadgets and gizmos” targeting audio needs of the radio broadcast market. Products are sold through a number of U.S. and international dealers. Examples include the Guest Gizmo and the Bidirectional Balancing Gadget. A recently introduced Bluetooth Audio Gadget is intended to make it easier to put a smartphone on the air.

Separately, Angry Audio is acquiring the StudioHub product line, which it currently resells, from Radio Systems and developer Mike Sirkis.

“Angry Audio is buying StudioHub and will soon begin manufacturing the entire StudioHub line including cables, adapters, panels, breakout boxes and hubs, matching amplifiers, etc.,” Dosch told Radio World in an email.

[Related: “Radio Systems Turns a Business Page”]

“Additionally, we will be providing spare-parts support for products previously manufactured under the Radio Systems brand. Millennium consoles for example will soon be supported by Angry Audio. We’ve moved into a bigger space to accommodate the expanded product line and hope to have operations humming along next month.”

Dosch said his last day with Lawo will be next week.

Deter Stinging Insects at the Transmitter Site

Radio World
5 years 9 months ago

Tom Johnson and I were talking about pests.

Fig. 1: Eaves and overhangs at unmanned transmitter buildings can attract stinging insects.

We met at the Alabama Broadcasters Association and Larry Wilkins’ Engineering Day seminar; and as we talked about bugs infesting transmitter sites, Tom shared the picture in Fig. 1.

I don’t know many engineers who care for wasps, hornets or other flying, stinging insects. Tom’s photo is a great reminder to spray under eaves, and around door and window frames — any place that’s protected from the weather.

Unfortunately, with cold weather approaching, it’s not just vermin that seek shelter from the cold. An unoccupied transmitter building or AM antenna tuning unit is an ideal home for insects and rodents. Make sure it is sealed.

ATUs in particular can attract unwanted guests. If your ATU has a light fixture inside, wait til it’s dark and then  turn it on, then walk around the ATU looking for any escaping light (remember to look underneath, too; and also watch out for the “hot” tower). Any holes you spot, perhaps where bolts once held coils or other components, are “welcome signs” for insects, and usually the proper diameter for these insects to squeeze through. Plug those holes with RTV or caulk.

Remember also that before opening the ATU door, pause to watch whether stinging insects are flying around. They may have infested your enclosure already.

Check that entry panels or doors to the ATU also fit tight; again look for light leakage. Remember that field mice can squeeze through amazingly small crevices.

Tom waited till dark, then sprayed that nest and its occupants.

When I did contract work, a client was losing their satellite signal every day at dusk. I stood on a ladder and unscrewed the LNB. A swarm of angry wasps escaped the nest they built inside. How we didn’t get stung —  or break a leg, frantically jumping off the ladder — still amazes me.

As I mention in my Workbench sessions, a one-liter clear plastic water bottle fits nicely in the throat of a satellite feed horn and will prevent infestation. As for your building, a good spritz of wasp and hornet spray applied under all the overhangs on your building is good preventive maintenance.

San Francisco contract and project engineer Bill Ruck writes, “Been there, done that.” He was referring to the electrolytic capacitor woes we described recently.

Back around 1967, Bill learned about electrolytic capacitors working at a hi-fi store. Rule of thumb in those days was (1) if they’ve “puked their guts” by exploding, replace them; (2) if not, replace them anyway.

Since then, Bill’s experience is only worse. Many times he has traced spurious outputs of an FM exciter to the power supply oscillating and modulating the carrier.

Recently, Bill had two BE FX-30 exciters with that problem. The issue was traced to the FMO module. The problem was that the FMO is potted and to dig out the potting compound to replace the capacitors would take a lot of time and was no longer cost-effective. The group owning the exciter preferred to purchase a new exciter rather than put a lot of money into reconditioning something that was over 30 years old.

Bill adds a few more nuggets to consider:

1. Although high ESR (equivalent series resistance) doesn’t cause “ringing,” it does let an unstable amplifier oscillate. Furthermore, most three-terminal regulators can be defined as an “unstable amplifier” and will oscillate. Bill learned in his own home-built power supplies to put a 1 uF tantalum bead capacitor and a 0.1 uF ceramic disc capacitor as close to the regulator IC input pins as possible.

2. Always put in 105 degree C electrolytic capacitors. They’re slightly larger and slightly more expensive but they last a lot longer.

3. It takes the same effort to remove capacitors from a printed circuit board to measure them, than to just replace them. Yes, Bill can measure ESR and capacitance, but he does that only to confirm his suspicions, after putting in new low ESR 105 C replacement capacitors.

In summary, Bill writes that these days, component level repair is less cost-effective than during his misguided youth; but if you do make these repairs, replace!

Fig. 2: Find this DIY rat trap at the YouTube link in the text.

Our Workbench Malaysian connection, broadcast engineer Paul Sagi, found an interesting YouTube video that we’ll call “Curiosity Killed the Rat!” Here’s the link: https://m.youtube.com/watch?v=T-KJMM55A9A

Paul comments that it appears that clear box sealing tape was used to hold the grain, and the “ramps” appear to be floor tiles, placed so the underside faces up. Placing two ramps on opposing sides permit some rats to balance out each other, a single ramp may be better. Finally, for remote locations, Paul suggests affixing the ramp to the bucket, so it doesn’t fall.

My comment? I sure hope this isn’t someone’s transmitter site! That’s a lot of rats.

I also hope you’ll contribute to Workbench. You’ll help your fellow engineers and qualify for SBE recertification credit. Send Workbench tips and high-resolution photos to johnpbisset@gmail.com.
