Three public media companies are working together to train broadcasters to develop programming for podcasts.

PRX, PBS Kids and the Corporation for Public Broadcasting announced a new project called the Ready to Learn Podcast Accelerator, a podcast training and development program for producers looking to create educational content for children. The program will take place virtually over 16 weeks starting in May and run through September. As part of the program, five production teams will be chosen to develop and create family-friendly audio content through a processing- and skills-development podcast program that will touch on everything from preplanning through the production process.

Creators in the program will receive 16 weeks of virtual podcast training led by PRX, a nonprofit media company, in tandem with children’s programming experts from PBS Kids. That training will include workshops, webinars and intensive sessions focusing on concept development, audience, community engagement and production values. The selected groups will also receive $10,000 in funding to assist with production and operational expenses. The deadline to apply is March 19.

The three companies are encouraging production teams with a demonstrated level of interest in children’s storytelling and education media to apply. In addition, independent production teams, public media station teams or teams from U.S.-based media organizations are encouraged to submit new podcast ideas for the children’s media landscape, especially content that centers on diverse voices and communities.

Content may be submitted in any genre, but should center on introducing children ages 4–8 to the world of work. This includes exposure to a variety of career and job options as well as development of social and emotional and executive functions.

The application submission window is open through Friday, March 19. More information can be found at the program website here.

The National Association of Broadcasters has come out strongly against the idea of changing the FM booster rule to allow geo-targeting. It says such a change could undermine the very business model of U.S. radio.

The NAB filed comments to the Federal Communications Commission on the proposal from GeoBroadcast Solutions.

GBS has been garnering support from various stakeholders in and outside of radio; and the company has received a friendly hearing from at least two FCC commissioners in recent months. But NAB’s strong opposition introduces an important new element to the debate.

The association says enabling geo-targeting “will depress advertising rates and revenues at a time when broadcasters already face enormous economic and competitive challenges.”

“The vast majority of broadcasters — from a wide array of perspectives — agree that permitting program origination on boosters will almost certainly drive both advertising rates and revenues down even further as advertisers push to purchase geo-targeted ads,” NAB wrote.

“The outcome is unavoidable, given the obvious business incentives for advertisers to purchase spots that cherry-pick what they view to be their most desirable customers and at a lower cost.”

Further, it could “lead to cannibalization” among stations, and it could hurt smaller stations, including minority-owned ones, in particular. This is a notable point because the possible benefits to small and minority broadcasters have been one of the big selling points for proponents of the GBS system, which has attracted support from a number of minority advocacy groups.

Further, NAB feels that revising the rule could lead to listener confusion, hurting consumer perceptions of the FM service; and it could result in unwelcome “red-lining” of certain listeners.

“While geo-targeted news and information could benefit certain parts of a market, it could also facilitate the geo-targeting of advertising away from certain parts of a radio market based on the demographics of an area. If given the opportunity, radio advertisers may simply direct their ad dollars to zoned ads aimed at their favored customers, especially since geo-targeted ads will cost less than market-wide ads. Listeners in some sections of a market, such as low-income areas, could find themselves ‘redlined’ out of certain radio advertisements.”

Although noting that some broadcasters and other organizations have officially expressed support for the idea, NAB said its own radio members “overwhelmingly and vehemently oppose amending the booster rule. … Any potential benefits of permitting geo-targeting are speculative at best and far outweighed by the far more certain, potentially seismic risks to the business model of FM radio.”

(It added that most of the filed comments in this proceeding so far are “essentially identical and submitted by one attorney who represented GBS in previous requests to modify the booster rule.”)

NAB advised the FCC that if the commission still thinks the whole idea is worthy of further consideration, more real-world testing is needed.

GeoBroadcast Solutions issued a statement Wednesday that didn’t mention NAB’s comments specifically but said that it views the current phase as “the beginning of an active debate on innovation in the radio industry.”

It quoted GBS spokesman Robert Udowitz saying, “Some parties oppose new technologies and innovation, and that is a familiar story for those who have watched broadcast media evolve over the decades. However, a broad range of large and small stations and broadcast groups, the advertising community, and minority coalitions, have indicated their desire to embrace innovation and the future by using broadcast airwaves for a more personal and localized experience.”

Radio World will provide a sampling of other filed comments in subsequent reporting. Initial comments were due today; reply comments are due March 12.

An enhanced image of Digidia’s facility in La Chapelle des Fougeretz, near Rennes

RF manufacturer Nautel has acquired Digidia, a digital radio technology firm based in France, saying the move adds significant DAB+, DRM and synchronous FM technology to its offerings.

Terms were not stated in the announcement.

Nautel plans to continue to operate the two businesses as separate entities.

Nautel highlighted Digidia’s expertise in high-power electronics design and digital signal processing, saying it has “rare design knowledge” in DAB+ and DRM.

Digidia also has been involved in specialized projects such as a highway system in central France using synchronous FM on 107.7 MHz with TDF, a DAB tunnel project in Hong Kong and projects to provide radio reception in various European mountain tunnels.

Digidia was founded in 2005 and is a member of the WorldDAB Consortium. Its product line includes specialized digital radio gear such as multiplexers, content servers, modulators and IP gateways. Nautel said Digidia products are used in some 300 digital radio deployments.

Nautel is headquartered in Nova Scotia, Canada, and with a significant facility in Maine.

“Digidia will continue as a separate entity, serving its customers out of its fully integrated design and manufacturing facility in Rennes, France,” Nautel announced. “Former shareholders Hermann Zensen, Manuel Billot and Damien Bernard will remain as executives for the two companies.”

The announcement was made by Nautel President/CEO Kevin Rodgers and Digidia Sales Manager Hermann Zensen. Rodgers said with this acquisition, Nautel “is underlining its commitment to all major digital radio transmission standards.”

Bryan Waters is chief engineer at Cumulus Media Atlanta. After 25 years in broadcast radio, including 13 years in engineering, he says, “I learn something new every day.”

This article appeared in Radio World’s “Trends in Codecs and STLs for 2020” ebook

Radio World: How are design and performance of codecs for radio changing?
Bryan Waters: One of the more important trends I am seeing lately with codecs would really be on the STL side. You see more MPX codecs hitting the market, giving more flexibility to broadcasters who want their gear at the studios where it is accessible, but still want the sound of the composite output at the transmitter.

With most units giving built-in failover and/or multiple network interfaces, one piece of gear at a site can get you everything you need.

RW: How are these technologies being deployed to address problems in new ways?
Waters: Codecs have opened up the world for those “hard-to-reach sites,” the situations where you’d never get a STL shot but you’ve got internet.

With Atlanta’s ever-growing metro, a traditional 950 MHz link is not always possible. We deal with it by running GatesAir IPLink MPXp units as our primary STL system, using a mix of composite and AES running over fiber between five sites. With the web GUI, we are able to monitor everything from studio to transmitter site.

RW: What about broadcasting from home?
Waters: Codecs have kept the industry alive during our days of COVID-19 quarantine. From the standard Comrex and Tieline “remote gear” to online sites like CleanFeed.net, we’ve had to find ways to bring co-hosts together virtually, enabling them to still interact with the audience, without it sounding like a train wreck. Though occasionally …

[Check Out More of Radio World’s Ebooks Here]

RW: How powerful can codecs get?
Waters: I think the only limitation is our imagination. Where there is a need, there will always be a person building something bigger, better and stronger.

RW: What functions and features are being offered on new models that engineers who haven’t bought a codec or STL in a while should know about?
Waters: I don’t know if there is a function or feature that would stand out to me, as much as the stability of IP codec units now.

Eight to 10 years ago, an IP codec seemed like a good alternative for remote broadcasts; but the stability, along with a basic lack of network infrastructure, made it a less-than-optimal choice for STL. Today, whether the pipe is big or small, you have available options to get your audio delivered and sounding good.

What will radio’s future air chain look like? A newly announced session of the Pro Audio & Radio Tech Summit on April 1 will explore that question.

“Building the Virtual Air Chain,” sponsored by RCS, will include panelists Roz Clark, who is senior director, radio engineering for Cox Media and chair of the Next Generation Architecture working group of the NAB Radio Technology Committee, and Alan Jurison, senior operations engineer, iHeartMedia Centralized Technical Operations and the chair of the Metadata Usage Working Group within the National Radio Systems Committee.

Alan Jurison

“Radio is adopting new technologies and practices from the information technology industry for its own success,” said Radio World Editor in Chief Paul McLane, who will moderate the discussion. “What will the infrastructure of the future look like — and will we even have one? How far will the industry go toward a ‘virtual air chain’?”

The summit, announced last week, is a free one-day virtual trade show where radio and pro audio professionals can learn about new products and technology and network with colleagues and manufacturers. Organizers reported strong initial registration after the announcement.

It is produced jointly by Mix magazine, Pro Sound News and Radio World.

The summit will feature a virtual exhibition floor, live chat and a separate track of presentations showcasing technologies and trends in pro audio.

The radio keynote session “Hybrid Radio & Android Automotive” will provide a look at two technology topics that affect how radio stations are heard in the car.

Registration for the event is open.

The duo MLEMON

Lots of folks sing in the shower. I happen not to — even the water would boo — but I bring it up because that’s where I do a lot of creative thinking.

There’s something about the steam and sound that allows my mind to drift. Wherever your happy place, plan on spending some quality time there because it seems that this pandemic isn’t leaving anytime soon.

To retain and even grow your audience during this time when lifestyle patterns and priorities are in flux, you’ve got to be in a good frame of mind.

I’d like to lay out what I believe to be a path toward engaging your audience. While I can’t solve this specifically for you, I’m hopeful that these thoughts will jumpstart your creativity during that proverbial time in the shower.

1 — What are musicians doing these days?

Many are writing, producing and recording, recording, recording.

A local duo that I follow in DC called MLEMON has done four full albums since last March. They are not alone in their creative output. There are artists in your back yard doing the same.

While the barrier to releasing new materials has never been lower, the ability to reach a big audience is especially challenging with shuttered venues everywhere. Radio to the rescue!

As a role model for this potential promotion, take a peek at NPR’s Tiny Desk (Home) Concerts. Instead of performing on-site at the Tiny Desk, the norm for over a decade, musicians are recording at home.

NPR also conducted its annual Tiny Desk Contest this pandemic year, capturing over 6,000 entries. You can read the rules for yourself, but I’d like to point out that one fun requirement is that every video include a desk. There’s even a sponsor, State Farm.

Linda Diaz on NPR’s YouTube channel.

Leading up to the winner, NPR featured many of the entries on-air and then followed up by making their winner a featured guest on “All Things Considered.”

Could you pull this off? Yes! This can be done locally and during the pandemic. It has the potential to create huge buzz in your social media, your local press, and TV newscasts.

2 — Next stop: Fashion.

We may be stuck at home, but most of us still gotta get dressed.

This headline from inStyle caught my eye: “How Will Kim Kardashian Dress Without Kanye West Controlling Her Closet?”

No matter what your format — it could even be talk or news — there are many listeners who are interested in or at least curious about this subject.

Also, fashion is something that can be done from home. Create a fashion contest with best-of categories, some of which could be pandemic-specific: masks, lightweight gloves, indoor shoes.

And where would we be in 2021 without Best Unmatched Top and Bottom for Zoom Calls?

Post pictures and videos on your social channels and/or website. Have judges and a Listeners’ Choice award. Could you find a local clothing store as a sponsor? Of course you can.

3 — It seems that animals are endemic to the pandemic.

If you’re not on a lot of Zoom calls, let me share that nearly every call I’m on features a pet’s enthusiastic greeting. While it’s usually dogs and cats, I have also met a talking bird named Buddy and the occasional fish or reptile. Do they distract on the calls? Yes, they do, and man, do people love that distraction.

Adopting or fostering shelter dogs and cats are a huge thing right now as people need companionship and many are isolated. You can easily become part of promoting pet adoption through this process already in place in your community.

You could bring back David Letterman’s timeless “Stupid Pet Tricks.” Of course, you could also do contesting around this one with winners for the best bark or mellowest meow. You could have awards for the prettiest and, yes, the ugliest. Ugly pets can most certainly be adorable just because they’re so strange-looking.

4 — Couples therapy!

What happens when those in committed relationships can’t escape each other because they’re trapped in the same apartment or house, month after month? The time has never been better for a late night call-in therapist who specializes in Just A Little Too Much Togetherness.

This has all the elements that make for compelling radio: comedy, tears, marriage, divorce and more. Don’t have a host? Hold live on-air auditions with therapists in your city and then have listeners vote on the winning host. Of course, they will be doing their show from home. It may even help the show if their spouse, kids or pets would interrupt the live broadcast once in a while!

Our recent ebook “Console Tech 2021” explores how the physical and virtual surfaces that radio stations and online audio creators use are evolving.

Johan Boqvist is senior product manager, radio on-air at Lawo.

Radio World: Name a specific feature or option of your surface or GUI that you wish to highlight.

Johan Boqvist: Modern radio consoles are no longer standalone physical devices, but are steadily becoming a combination of physical and on-screen interfaces that complement and mirror each other. Lawo has led the way in this area with a software GUI called VisTool, which comes with every Lawo radio mixer, runs on Windows PCs and supports touchscreen controls. 

Lawo was one of the first companies to augment physical controls with virtual controls, which makes VisTool the most mature console GUI on the market.

RW: What makes it notable?

Boqvist: While every Lawo console comes with a basic version of VisTool, there’s an Unlimited version that allows users to completely customize the look, feel and layout of the control GUI with their own

Lawo VisTool Unlimited GUI builder software

layouts and graphics.

They can literally build a virtual console with it, complete with on-screen, touch-sensitive faders, rotary controls, meters, pushbuttons and more. VisTool can even integrate controls for studio peripherals, including playout systems, phones, codecs, video feeds and social media platforms, etc.

[Related: “How to Choose Your Next Radio Console”]

What makes this notable is that broadcasters have begun to use VisTool not only to control their consoles, but their entire studios. They’re building remote-control solutions with it, where a remote operator connected via IP has complete access to all studio equipment and can run it as if they were physically present in the studio. 

Remote studio control setup using VisTool along with a Lawo console at the Sutro Tower transmitter site.

In these days of social distancing, this has proven to be a very in-demand solution, both for stations seeking to be prepared for emergency operation, and for remote talent working from home studios or other locations.

RW: What are other notable features available now in surfaces that may not have been a few years ago?

Boqvist: We’re seeing more and more automation features appearing in radio consoles.

Lawo has pioneered this, with things like AutoMix automatic group mixing and Autogain mic gain features, and also with the ability to set, save and recall settings, customized to individual talent, through the use of snapshots and motorized faders. Built-in touch-sensitive GUIs beginning to appear in radio consoles as well, a feature that was previously available only in large live-sound audio consoles like Lawo’s mc2 series.

RW: For someone who hasn’t bought a console recently, describe the level of “customization” available.

Boqvist: All Lawo radio products are customizable to meet every customer’s unique requirements and workflows. This means console configurations from two to 60 faders, with IP and/or baseband audio interfaces, redundant and non-redundant DSP cores, power distribution, network interfaces and protocols, and a number of DSP licenses and software add-ons to choose from, depending on the application.

The behavior, logic, functions and labels in the console and virtual extension are fully user configurable with the help of intuitive, use-to-use graphical editors and software. 

But if the customer doesn’t require custom configuration, Lawo radio consoles can be delivered with a standard configuration and pre-configured plug-and-play applications.

These standard configurations are frequently updated by our configuration experts based on user feedback and market requirements, to meet the requirements for the majority of radio installations. These standard configurations can also be used as baselines for Lawo’s engineering team to use when collaborating with clients to develop custom solutions.

RW: How many surfaces can an “engine” accommodate?

Boqvist: Great question! But there’s no set answer for every engine and every manufacturer; it depends upon the hardware used. Obviously, hardware with greater power and resources is better.

In Lawo’s case, we have been receiving more and more requests for shared and distributed DSP resources, and for good reason — this approach not only saves money, rack space and power (an environmentally friendly alternative), it makes possible many new options for sharing audio and logic between “logical consoles” and studios without external connections. Our solution is Power Core MAX, a license option for our Power Core DSP mixing engine, which is a 1RU device that’s one of the most powerful DSP devices ever made for broadcast. 

MAX is short for “Multiple Access,” and this license enables the Power Core device to host up to four consoles, either physical, virtual or any combination of the two. The current generation of hardware supports up to 60 faders and 96 parallel DSP channels. That’s more audio resources than a typical single radio application requires, but ideal for sharing those resources among multiple smaller control interfaces. 

Our clients tell us this is a perfect option for multiple consoles in a single studio, or for co-located studios in close proximity, since physical I/O can also be easily shared as well as control. 

Other applications are virtual remote studios with a shared core and DSP engine deployed in a datacenter, with audio connectivity over Ravenna/AES67. Power Core units already in the field can be easily upgraded to MAX functionality with a simple license upgrade.

RW: How will the role of physical surfaces change in the next five years?

Boqvist: Like the rest of the industry, Lawo clearly sees a trend towards more and more virtual consoles and interfaces. As pioneers in virtualization, first with the development of our VisTool graphical control interface, and then with our RƎLAY virtual mixing and routing software, we support this trend and have plenty of experience, having helped customers around the world to deploying virtual user interfaces for production and live broadcasting.

At the same time, customers still want modular physical consoles, very often in combination with virtual interfaces. While we believe that a virtual interface can’t completely replace a physical surface in every application, we think that modular and hybrid console combinations, with open APIs for software integration, are the future. 

This enables flexible deployments and solutions designed for a common and unified workflow across a number of different application scenarios. Lawo Product Management and R&D are working with our UX team and with our clients to develop some exciting products in this vein, which are scheduled for next year, with interfaces that bring modern design and consistent workflow patterns together to unify the overall user experience — whether clients choose physical consoles, virtual consoles or a mixture of both.

Dielectric equipment inside the transmitter shack at WSRQ.

From our Who’s Buying What page: antenna maker Dielectric said consultant Hal Kneller specified DCR-T antennas for FM translators for AM stations WSRQ(AM) in Sarasota, Fla., and WMDD in Fajardo, P.R.

“WSRQ’s translator for 106.9 FM (W295BH) is part of a blended SFN and simulcasting network that synchronizes programming across four stations in the Sarasota/Bradenton market,” the company stated.

[Related: “Hybrid Synchronization in the Sunshine State”]

“In an effort to improve coverage the 250 W translator, previously located in Bradenton, was moved to Sarasota following FCC approval. While the move would establish a stronger signal with better building penetration, the existing ‘budget antenna’ had suffered recent water damage and would not suit the signal’s new directional pattern,” Dielectric wrote in a project summary.

“Kneller kept the station on the air with a backup system while the one-bay DCR-T antenna was installed on its new tower, which he described as ‘very busy and loaded.’ The compact DCR-T design was top-mounted on the 475-foot tower, using a tower pipe initially intended for cellular antennas. The top-mounted position, combined with the directional pattern designed for the translator, has substantially improved the translator’s effectiveness in the all-important Sarasota area.”

Dielectric DCR-T antenna at WMDD.

Kneller is using two Dielectric FM filters for the Sarasota transmitter building, with one feeding 106.9 MHz and the other feeding a system on 99.1 FM.

The WMDD system in Puerto Rico simulcasts the main AM signal on 106.5 MHz. The translator is 30 miles outside of San Juan; the translator is on the AM station’s 400-foot tower.

DTS AutoStage promo image

Xperi has officially announced the renaming of its DTS Connected Radio hybrid radio platform as DTS AutoStage.

Radio World recently reported the change after the company did a “soft rollout” of the new name during the online CES show in January.

[Related: “Summit to Explore Hybrid Radio, Android Automotive”]

In a press release the company expanded on the reasons. Xperi said the move reflects “the broad application of the platform within automotive infotainment systems.”

DTS AutoStage recently launched in the Daimler MBUX infotainment system, so it is showing up in vehicles like the Mercedes-Benz S-Class. Xperi said the platform also won a 2021 Business Intelligence Group (BIG) Innovation Award.

“The rebrand to DTS AutoStage was in part driven by the opportunities resulting from Xperi’s merger with TiVo in June 2020, which enabled the integration of TiVo’s world-class music metadata and personalized content discovery engine,” according to a press release.

It said the branding represents the entertainment “stages” the platform offers as well as how it can “amplify those stages as in-cabin technology continues to evolve.”

Recently announced features include lyrics, content metadata and personalization capabilities.

Xperi said its partners now include Entercom, Beasley, Cox Radio, Bauer Media and Global Radio, as well as regional platforms FM World, Quu Interactive, Radio.com and RadioApp.

Hybrid radio systems combine over-the-air reception with an internet connection that delivers metadata and can allow “service following” in which a receiver switches automatically to a station’s stream when the car is out of the range of the broadcast signal.

UNESCO has declared the 2021 World Radio Day theme to be “Evolution, Innovation, Connection.”

It also the 10th anniversary of WRD. UNESCO Director-General Audrey Azouley issued a statement: “More than ever, we need this universal humanist medium, vector of freedom. Without radio, the right to information and freedom of expression and, with them, fundamental freedoms would be weakened, as would cultural diversity, since community radio stations are the voices of the voiceless.”

Radio is more than 110 years old; the World Radio Day, which was adopted by the United Nations General Assembly as an international day in 2012, will be 10 years old on Feb. 13 (while the life-changing pandemic is only one though it feels like a hundred).

While we read about the excellent results of Spotify in Q4, the spread of podcasting, are we celebrating or commemorating radio? It all depends on whether we look back at the past or try to reinvent radio for the current times and the future.

[Read: WRHU to Go Worldwide on February 12–14]

The international, not-for-profit DRM Consortium feels totally in tune with the three 2021 WRD themes: evolution, innovation and connection. They are wide and lofty enough so that any new technology or platform could subscribe to them. But we are demonstrating practically how radio can evolve and invent what is needed now.

The compression delivered in digital enables up to three audio DRM programs and one data channel on one AM or FM current analog frequency. DRM has been mainly tested, and rolled out for its excellent audio qualities, even in the less forgiving shortwave and medium-wave analog bands DRM delivers combined information like audio and data (i.e., text, pictures, maps etc.) that can enable vital services like the Emergency Warning Functionality to be received on digital radio sets.

It is the pandemic that has forced us to look at the DRM audio and data combination in another context, as an innovative learning platform for all. We looked more closely at the data carriage channel. Data means files, and files represent anything from pop song titles and singers’ pictures to stock market prices or maps and the RSS feeds made available through the universal medium of radio. At least this was the kind of illustration we used to give before 2019. In 2020 we realised that this unique combination of audio and multimedia services, available on a standard digital radio set delivered via terrestrial broadcasts (i.e., one to many, and as many as needed), can offer a real solution for distance learning where the internet is patchy, non-existent or the modern gadgets are rare and unaffordable.

For most, e-learning means nowadays something done via the internet. But internet penetration varies between about 95% in the United States (where 73% own a personal computer), to slightly above 50% in Asia and under 40% in Africa. And this has created yet another information and education gap, as amply documented elsewhere.

Can DRM Be the New Teacher?

DRM can deliver typical classroom education, as well as lessons for personal self-study. Instead of giving the same FM content, or similar, on one of the two extra digital channels, a broadcaster might choose to use one of the available DRM digital channels to broadcast lectures or lessons at certain times of the day. In parallel, complementary lesson notes, full textbooks including graphics and formulas, illustrative images, quizzes etc. can be displayed and cached after being loaded and made available through the Journaline application. As the data is repeated on carousel, they can also be used as notes to the lesson to be referenced during the class or be accessed for self-study at any time and as many times as needed afterwards. The Journaline application helps with the structuring of the information by language, class level, subject, and chapters, for easy navigation by students and teachers, too. The idea has certainly got a lot of attention in India and some African countries.

DRM School Demo

If a DRM receiver is not available or too expensive for individual students, DRM radio sets that are optimized for the radio schooling use-case may provide a built-in Wi-Fi hotspot feature, allowing anybody nearby to access the full DRM audio and textbook content. This means a single DRM receiver can be used for communities, households, or classrooms, still giving every student or user full control over navigating the content at their own pace.

Digital Radio Distance Education

In this instance the digital receiver functions as a “mini-station” that feeds cheap Wi-Fi devices or a larger screen placed in a community center where, if allowed, many students can enjoy informative, modern lectures.

DRM digital radio cannot mirror the richness of internet when this is available, affordable and working. DRM or digital radio e-learning is a more compact offer. It needs a highly structured presentation of the essential content with only the key notes, images and notes available. The information is presented in a logical and structured way. Maybe this is the essence of good and intelligent teaching and learning. Synchronization of audio and visual material broadcast terrestrially is a challenge and has its own limitations, so less is more as quality always trumps quantity.

On Feb. 13, the World Radio Day, we are highlighting DRM as a distance learning platform by launching our education DRM ebook, DRM for Education.

Being a “one-to-many” platform, digital radio can deliver audio and text over vast areas and, therefore, to all the schools and students in villages far away or in busy cities, with the same content and quality and without any discrimination.

On Feb. 13 we are also launching in parallel with our ebook, DRM Delivers Education for All Initiative, which is a project you may want to learn about, get involved in, support and implement. If so, please contact us at projectoffice@drm.org.

World Radio Day is a celebration. And what better way to support evolution, use innovation, and enhance connection than through DRM, a sure way to bring a 100-year-old friend to the new generation in the guise of a knowledgeable and encouraging teacher!

iHeartRadio has launched a big 3D audio effort and announced a “strategic expansion into binaural podcasting.”

It promises to put listeners “into the middle of an audio soundscape, immersing them in the story like never before.”

It released this audio sample to promote it. “Put your headphones on,” it states.

The company plans to introduce a slate of podcasts using this technique.

“Binaural, or 3D audio, creates a sense of movement, location and triggers other senses,” the company wrote in its announcement, “enhancing listening experiences and providing a new way for people to hear high quality, surround sound, immersive content, and reproducing real-life experiences, much like virtual reality has done for video, right in their own homes.”

The announcement was made by Conal Byrne, president of the iHeartPodcast Network. Byrne was quoted describing the technology as “virtual reality for the ears,” a more immersive way of listening.

It said its binaural audio series “13 Days of Halloween,” produced with Blumhouse Television, drew 2.8 million listeners and that it will expand te franchise to other holidays.

“The new iHeart 3D Audio slate will also include the upcoming podcast ‘The Mantawauk Caves,’ a co-production with Blumhouse Television, as well as a series of bonus 3D episodes across the year for hit shows like ‘The Ron Burgundy Podcast,’” it stated.

A company spokeswoman wrote in the announcement, “The tech has been wildly underused in podcasting, and the move makes iHeart the first company to carve out a substantial stake in the space.”

Tom Lawler is a contract studio/RF engineer who builds and maintains analog and AoIP radio and home studios for broadcast; his full-time job is in field technical services for RCS. We spoke to him for the Radio World ebook “Trends in Audio Processing for Radio.”

Radio World: Tom, what do you see as the most important trend in the design and use of processors?

Tom Lawler: With the development by leaps and bounds in flexibility — between insert patch points for ratings watermarking, multimode boxes, as well as being able to do MPX over AES or AoIP — modern processors have become virtual Swiss Army knives. Not to mention that devices like StreamBlade from Wheatstone or software processors like StereoTool let your online presence have just as much punch as the OTA signal. 

It wasn’t that many years ago where the only option was to try and adapt an FM box or use a PCI card that couldn’t be easily updated.

RW: What should readers know about the differences in processing needs for analog over the air, digital OTA, podcasts and streaming?

Lawler: Every medium requires a different approach, but they all require you to have as clean a source material as possible. 

With analog OTA you can get away with clipping/limiting to achieve loudness without introducing fatiguing artifacts — but that approach won’t work with digital OTA as artifacts will cause issues with the bit-reduced codec. For podcasting, use a gentle multiband to smooth over transitions between segments/presenters — resist the urge to treat it like FM! 

Streaming can be treated like FM, but make sure to use lookahead limiting instead of clipping — also, make sure everything is in-phase for when it’s folded down to mono on a smart speaker.

RW: How will the concepts of the cloud, virtualization and software as a service affect the processing marketplace? 

Lawler: I hope that it will lead to greater flexibility, redundancy and better quality. Imagine no STL issues to contend with (as long as your ISPs are up), and you now have the ability to make upgrades with the click of a mouse rather than having to physically rack up gear.

This is a great opportunity for users as well as vendors alike — users gain as much flexibility as they are willing to pay for, and vendors can have a reliable subscription income stream. Plus, there is no single point of failure like in a traditional plant.

RW: The pandemic is changing thinking about the need for big buildings and studios to make good radio. What does this mean for processing? 

Lawler: I think COVID-19 will accelerate moving to flexible software/cloud solutions for processing — and it will be more important than ever with the myriad of sources and level differences. 

Given that more and more talent is working remotely from home rather than at the studio it will be a challenge to keep everything sounding consistent from source to source. Not every home studio has mic processing, and many automation systems do not handle ducking gracefully. 

Adding processing in the cloud will be necessary to keep the audio consistent — more so now than before. This also means less in the racks to power and cool if done right.

RW: How is consumer behavior changing; for instance are younger consumers moving toward greater fidelity? 

Lawler: Things have come full circle almost. In the 1950s and ’60s you had a 3-inch mono speaker that went hand-in-hand with the explosion of top 40 radio. And now, we have smart speakers that are about the same size fueling another revolution in how audio entertainment is consumed. Apple and their just released new iPod touting greater fidelity, and the ability to pair them and create stereo, similar to other smart speakers. 

If this is how your audience consumes the station/stream/podcast, make sure to give them a download or on-demand stream that is easy to listen to no matter the environment. Make the most of the 3-inch speaker without sounding smashed. Do your content creators have access to the tools to process voice without making it sound unnatural? That is the trick with modern listening — making it pleasing while taking into account less than perfect conditions.

RW: In 2014 we did a story asking if processors had become as powerful as they could get. In 2020, where might further dramatic improvements come from?

Lawler: Never underestimate the ability to go further. My grandfather once believed that Cadillac would go no further than a dual points ignition setup — now look at what can be done with engine management! 

Tools like the limitless clipper in Wheatstone’s X5 or being able to generate a perfect composite FM signal from a 192 kHz PC soundcard with StereoTool. Six years ago everyone was asking what was next after the big three (Orban, Omnia, Wheatstone) took FM to as loud as could be asked — and all went in the direction of how to put the quality back in with such hyperprocessed source material from record producers. I can’t wait to see what the next six years bring!  

RW: What else should we know about processing for radio?

Lawler: Look at your entire audio path — from the quality of the files you are playing (WAV vs MP2/MP3), the STL, the exciter/transmitter, and even the antenna. Any one of those could be the reason you cannot achieve the sound you are looking for. And as the old saying goes “Garbage in, garbage out.”

The post Lawler: Listening Has Come Almost Full Circle appeared first on Radio World.

Jim Schultz primarily does electrical contract work of all types for broadcast stations and telecom and data facilities. Along the way he has been involved in several transmitter installs.

Jim confesses that radio has always been a first love. For him the relationship started, like many in the biz, with a Knight Kit wireless broadcaster kit when he was 9 years old, six decades ago.

Although he spent a few years on both sides of the mic in medium-market radio, he now has owned his own business as a Connecticut E1 Unlimited Electrical Contractor for almost 40 years. Let that be an encouragement to anyone thinking about starting a contract engineering business!

Jim has been following our discussions about bonding and grounding in Workbench and took note of Wayne Eckert’s drawing of a properly grounded pole in December.

Jim suggests adding a bonding kit where the coax feedline leaves the pole, and a #6 or larger copper bonding conductor from the grounding electrode to the power/telco/ CATV station ground.

Fig. 1 shows a typical ground kit, available from CommScope.

Mark Jensen is president of MWB Broadcasting, which owns stations in Nebraska and Hawaii. On a recent Idea Bank conference call, Mark related that an abundance of flies had made working inside his transmitter building unpleasant. Not only that but the flies were getting sucked into the transmitter, causing expensive damage.

Mark’s solution was to install bug zappers inside the buildings. The light attracts and kills the flying insects, keeping them out of electronic equipment. Simple but efficient.

On the same call there was a discussion about keeping weeds down from around your transmitter building or tower.

Terry Barber is with Little Engine Broadcasting, in Montgomery, Ala. He has a billboard company nearby, with scores of old billboards on hand. The sections are of no use to the billboard company, so Terry has placed the old billboard sections on the ground, around his transmitter building, and covered them with gravel.

Since the weeds won’t penetrate the boards, any that do grow amidst the gravel can be pulled easily. Another inexpensive, effective, solution.

X marks the driver

You probably have a screwdriver set with both straight and Phillips drivers. You go to grab one and have to stop and look at the tip to see if it is the one you want.

Mark Peterson, engineer at WCTS(AM), in Plymouth, Minn., offers a solution: Take a Sharpie brand or similar permanent marker and mark the handles of the Phillips drivers. If you store drivers vertically, in slots or loops in the tool case, place a mark on the on the butt end of the driver — an “X” to indicate Phillips or a slash “/” for the straight blade.

Take a minute or two to do this and you’ll never grab the wrong driver again.

We love all these simple, yet useful, reminders.

Who needs a carwash?

Alan Peterson is the national production director for the Radio America Network and a longtime member of the Radio World family.

Our recent discussions about cleaning equipment using a hose or carwash reminded Alan of the time in the early 1990s at WLAD(AM)/WDAQ(FM) in Danbury, Conn., when an oil burner in the basement of the studios malfunctioned and filled the building with greasy smoke and soot.

Professional cleaning crews took care of the general office mess while, but the guidance of the late Tom Osenkowsky, Alan and a few other staffers took care of degreasing the electronic gear.

As Alan related the experience in the pages of Radio World, a reader suggested that a suitable way to clean an ITC triple-deck cart machine was to remove all rubber parts like pinch rollers and rubber feet, and run it through the dishwasher!

Alan fortunately hasn’t had a second shot at a station fire to test the idea, and cart decks have gone the way of the Conestoga wagon, so we can’t report any outcome of the proposed experiment. Perhaps Workbench readers can share one.

Smart water sensors

Jose Luis Bolanos is with Broadcast Services LLC. He attended a Zoom meeting for the Grand Rapids SBE chapter recently on which I spoke.

In the presentation on AoIP, I also mentioned the use of water sensors to protect both studio and transmitter sites from water damage.

Typically, these floods are caused by clogged condensate drains, but roof leaks in seldom-visited sites can be just as costly.

Jose Luis has been using water sensors in facilities as well, but his are battery-powered (Fig. 2).

Fig. 2: WER makes this Wireless Water Leak Sensor Alarm with 90 dB buzzer. We saw it on Amazon for less than $30 for a four-pack.

They will wail/beep when they come in contact with water. You’ll find them described at this Amazon link: https://amzn.to/37qSwQD. This set includes four sensors for under $30. Note that batteries are not included.

Jose Luis places the sensors in strategic corners or near AC condensate drain pipes — he had one of those clog once, and it started to drip water inside the transmitter building.

When the alarm starts, he can pick up the noise with a security camera that receives audio or an environmental monitor unit.

Nowadays, you can purchase water sensors that are connected through the internet (like everything else). These versions will send alarms to a smart phone/email.

Here is an Amazon link for these IP sensors, shown in Fig. 3, which cost less than $50 for three and come with batteries: https://amzn.to/3akUTWY.

Fig. 3: The Govee WiFi Water Sensor has an adjustable alarm but will also connect to WiFi and send emails, app notifications and alerts to your phone in the presence of a water leak. It’s around $50 for three. Note that it doesn’t support 5G WiFi.

WRHU Station Manager Catie Egan With Cove City Sound Studios Owner Richie Cannata

The author is the chief engineer for Salem Radio’s WMCA in New York, WNYM-Hackensack, N.J., and Hofstra University’s WRHU in Hempstead, N.J. He is currently working towards a Doctorate in Education at Hofstra University.

Some time ago sitting in traffic in the Holland Tunnel, driving home from a routine maintenance visit to Salem Radio’s WMCA 570 AM transmitter site in Kearny, N.J., I had a wild thought. World Radio Day, the official UNESCO event celebrating terrestrial broadcast radio, was approaching in a few months. Wouldn’t it be cool if I could help a team of students turn the ambitious college FM station where I work into a worldwide radio network for just one day? At the time, it seemed like a silly, impossible daydream. But then again, WRHU Radio Hofstra University 88.7 FM is a place built on dreams.

First signing on the air in the late 1950s, WRHU (formerly WHCH and WVHC) has grown from its small studios underneath the campus’ Spiegel Theater to the broadcast powerhouse it is today. WRHU’s FM signal covers all of Nassau County on Long Island and parts of New York City’s five boroughs and the tristate area. Over the years, the station has won multiple Marconi Awards, enjoyed a high-profile relationship with the New York Islanders hockey team, and trained a multitude of passionate radio graduates who have worked their way into the New York broadcast market.

Housed in The Lawrence Herbert School of Communication at Hofstra University, the station is powered by its 200-plus student volunteers. And this year, the station reached a new height — receiving the World Radio Day Award from the Academy of Radio Arts and Sciences of America.

General Manager Bruce Avery has spent the last 27 years of his career at the helm of WRHU. It was his passion for broadcasting and commitment to preprofessional development in an environment of mutual respect that helped grow the station to where it is today. Bruce has always stressed that WRHU is a student-run radio station supported by a diverse group of administrators, faculty, alumni and community volunteers.

WRHU Reporter Derek Futterman

To pursue this idea of a worldwide broadcast, I knew that the students would have to be in charge. I consulted with my colleague, Operations Manager John Mullen, on the best way to approach this. John is no stranger to big, globally successful ideas, having been program director for WBLS and operations manager for Hot 97 and CD 101.9 during their heyday in the 1990s. John and I agreed that the students would be best served by a broadcast that was a celebration of live and local radio, and that it would happen in two parts.

The first would be an actual global broadcast. WRHU would reach out to stations across the United States and around the world to invite them to join us for our special World Radio Weekend broadcast on Feb 12, 13 and 14. Student reporters and DJs would have the opportunity to do a bidirectional simulcast with each partner station. To accomplish this, we would use all of our technological options — our connectivity choices include Comrex Access codecs along with Telos VX IP phones and QGoLive soft codec apps for smartphones. Our updated studios feature the latest Wheatstone gear and RCS automation — to connect the World Radio Weekend broadcast affiliates with WRHU’s campus studios in Hempstead, essentially building an ad hoc network of international stations.

Finding interested affiliates was also easy. It turns out that radio geeks come in all shapes and sizes. WRHU alum and JVC Broadcasting owner John Caracciolo and Neversink Media Group’s Bud Williamson were the first to offer us airtime. We wanted to feature local stations that served their listeners with live and local programming. Established names like Pocono 96.7, Long Island News Radio, WKNY Kingston and WALL Radio seemed like a natural fit for the broadcast. From there the list grew longer. KBOO community radio in Portland, Ore., agreed to join us for a tribute to WCBS engineer and WRHU alum Marc Weiner, who passed away in 2020. Marc was a beloved technical mentor and friend of both stations, so it only seemed fitting to honor his memory as part of our joint broadcast.

WRHU Reporter Crystal Bermudez

Since then, the list of international and domestic stations has grown considerably. Bush Radio 89.5 FM, a community megaphone in Cape Town, South Africa, eagerly joined the program, along with Bradford City Broadcasting’s 106.6 in the U.K.; Taipei, Taiwan’s FM100; Florida Man Radio; South Seas Broadcasting’s KKHJ in American Samoa; and GGFM in the Philippines. For the Spanish-language segment of the broadcast, Hofstra University professor and Latin American radio scholar Mario Murillo will connect us with his partner station WIOX, Roxbury, N.J., where he produces a weekly Rumba music show.

The WRHU student team, led by journalists Derek Futterman, Rachel Luscher and Crystal Bermudez, has been hard at work preparing “WRHU’s World Radio Passport.” Listeners will have the chance to hear shows featuring music, voices and stories from stations around the world, all co-hosted by WRHU students.

“We want the listener to sit back and let the radio take them on this amazing voyage around the world,” said Futterman ’23, a journalism major.

More than 50 industry professionals were also interviewed as part of the production. WRHU students have spent the last two months gathering stories and radio experiences from radio’s household names such as 1010 WINS anchor Lee Harris, Q104.3’s Jim Kerr, WNYC’s Paul Cavalconte, ABC Radio’s Todd Ant, and MaryKate “MK” Burnell of the “More Music Please” podcast. Matching the students with professionals in their fields of interest proved to be very rewarding for both interviewer and interviewee.

WRHU Reporter Rachel Luscher

Students from the station’s news and sports departments, led by Professionals in Residence Pete Silverman and Sara Hendricks, jumped at the chance to chat with some of the nation’s top talents. Shayna Sengstock ‘22, a WRHU student technical engineer, loved having the chance to interview veteran CBS engineer Mitch Glider. “It was really exciting to have the chance to learn about these amazing professionals and what they do,” she said. “They provided so much inspiration for my own career.”

WDST’s Lenny Bloch also enjoyed his interview with WRHU’s Grant Francis ‘21, responding with “Great kid, great chat!” Even Long Island music legends Richie Cannata and Liberty DeVitto got involved, talking about the crucial role of local radio in the region’s music history. Student Director of Music Programming Ed Mabeeza now has the challenge of scheduling the entire program in RCS Selector for the weekend.

None of this would have been possible without the support of the Lawrence Herbert School of Communication and Dean Mark Lukasiewicz. Hofstra has given WRHU its support for over 60 years. On Feb. 12, we look forward to sharing WRHU with the world.

Hoping to advance its push for the FCC to allow geo-targeting content on FM boosters, GeoBroadcast Solutions has applied for 90-day experimental authority to run two co-located, on-channel boosters in San Jose, Calif.

Its goal is to collect more field data about the company’s ZoneCasting FM booster system.

“The test will be conducted through Universal Media Access’ KSJO(FM) in San Jose, Calif., a South Asian/Indian broadcaster,” the company said in an announcement.

“The trial will demonstrate KSJO’s ability to add localized weather and traffic, news, advertising and EAS tests during short parts of a broadcast hour, and how seamlessly unrecognizable it will be to the average listener.”

The filing was made by Bert Goldman Goldman Engineering Management, who will install the equipment if the request is approved. GBS said Dennis Roberson of tech and management consultant firm Roberson and Associates will oversee and audit the process.

Bill Saurer is president and CEO of Universal Media Access.

“The requested testing will use a back-to-back booster configuration setup at different locations near the busy I-680 corridor,” GBS stated.

Goldman was quoted in the announcement saying the goal was to show that ZoneCasting “can be very simply implemented, in this case, adding only one booster location and can significantly improve coverage in low signal areas while providing geotargeted programming which can benefit hundreds of thousands of listeners without interference.”

As we’ve reported, the FCC currently is taking industry comments about the GBS proposal on geo-targeting. That comment deadline is Wednesday.

GBS added that this would be its fourth experimental permit and the second using this booster configuration.
