The spring NAB Show is approaching. Between now and then Radio World will conduct several short Q&As with manufacturers about their plans and offerings, to help you get the most out of the big annual trade show. Jochen Richter is head of sales, Radio, while Clark Novak handles radio marketing for Lawo AG.

Radio World: How has business been for the company since last year’s NAB Show?

Clark Novak: Business has been excellent. AoIP networks have been installed by the world’s largest broadcasters, and now medium- and even small-sized radio stations are either actively planning for or investigating IP adoption. Lawo has always been a vocal proponent of standards-based networking, so the latest studies showing how AES67 has helped accelerate the AoIP transition are very encouraging. Those studies also theorize that ST2110 standards (for interoperability between audio and video systems) will spur AoIP adoption even further, which is why Lawo’s newest radio products are ST2110-30-compliant.

RW: What are you hearing from your customers about their business outlook this year? In what areas should we expect growth or the most interesting projects?

Jochen Richter

Jochen Richter: We’ve seen more investment in AoIP technology for joint TV and radio facilities — the RadioFr MediaPARC project in Switzerland is one of the most visible, along with projects by large public broadcasters in the U.S. and Canada. Engineering managers are seeing with their own eyes the monetary benefits and economies of scale that IP networking and interoperability bring to their tables.

RW: The last year has proven rather rocky for much of the radio industry with the largest group owner making a big move to chart a new business/operational model. Stepping away from your particular segment, what is your feeling for the overall health of the radio industry?

Novak: It’s true that the landscape has been changing in the U.S.A., but Lawo’s presence in International broadcasting has shown us changes of a different nature in other countries. Mostly, it’s for the better. We believe that, from a global perspective, radio is very much alive and very healthy.

RW: You’ve been active in the radio broadcast equipment market for many years. What’s the biggest problem or challenge facing users in this segment right now?

Richter: The biggest challenge for users will be keeping and improving efficiency in daily workflows, as radio broadcasters are increasingly called on to serve multiple platforms for linear plus on-demand services. Top management expects high efficiency, and that means all workflows have to be streamlined. Lawo is a great fit for the radio part; our software applications, like VisTool, provide collaborative platforms that easily integrate with both third-party applications and the RƎLAY family of applications for IP-streaming and virtual radio scenarios.

RW: What new goodies will your company be showing? Why should attendees visit your booth, C3012?

Novak: Radio is always looking for ways to maximize budgets, so we think people will really want to see Power Core MAX. It’s a new version of our very popular Power Core AoIP mixing engine that can power two, three or even four mixing surfaces, depending on how you size them. Very powerful, and very cost-effective.

We’ll also be showing AoIP Stream Monitor, which is the first diagnostic tool expressly designed for radio plants using AES67-compliant IP networks. You can build monitor walls with information for up to 16 critical streams, and look at detailed statistics for each one. It can even be virtualized to allow multiple screen displays with real-time status on dozens of channels. It’s an indispensable tool for modern radio.

Clark Novak

RW: AoIP and touchscreens have been technology marvels that have dazzled at the NAB Show in the last few years. Any cool stuff we should know about this year?

Richter: I think we will continue to see more touch-based mixing interfaces. They’re intuitive, easy to customize, cost-effective, and younger broadcasters love them. They’re a natural fit for AoIP applications.

RW: What do you anticipate will be the most significant technology trend at the 2020 NAB Show?

Novak: The interest in virtualization, and moving applications to cloud-based servers continues to increase. I believe more vendors will showcase products aimed at serving this interest.

RW: Will you be attending any sessions or looking forward to any events?

Richter: Lawo has already gained a lot of experience with large cloud-based infrastructure projects, so we plan to focus on sessions that center around all cloud-based production and processing workflows. We are very interested to see and be a part of shaping the next trends in software orchestration and workflow optimization.

RW: You’re a show veteran, how has the show changed since your first visit?

Richter: Since the mid-’90s, NAB has very clearly decided not to concentrate only on technology, but has changed its focus to workflow and business needs as well. The attendance by top management has definitely increased and this means decision makers are attending, which is good for the whole industry, and definitely for the business of radio. Finally, the convergence of media and the focus on user experience, including streaming services, are central points now.

This is one in a series of articles about what the industry is telling the FCC about all-digital on the U.S. AM band.

The National Association of Broadcasters says the FCC should allow individual radio stations on the AM band to convert to all-digital HD Radio transmissions if they wish to do so.

The FCC has proposed allowing AM stations voluntarily to broadcast in MA3 all-digital mode of the HD Radio in-band on-channel (IBOC) digital radio. Monday was the first comment deadline.

The NAB says experimental testing has demonstrated the viability of all-digital AM and that broadcaster interest in pursuing the technology is evident. “Allowing stations to voluntarily transition to all-digital AM service will benefit listeners with enhanced AM service and improve AM broadcasters’ ability to succeed in the increasingly competitive audio marketplace,” NAB wrote.

The carriers in an HD Radio MA3 signal are shown in a slide from the NAB Technology department.

The association believes digital for AM is the way forward and cites the propagation characteristics of the AM band as one of the reasons.

“Analog AM signals are vulnerable to RF interference from fluorescent and LED light bulbs, computer monitors, flatscreen TVs and other devices. NAB has noted that some automakers are choosing to exclude AM radio from their all-electric vehicle dashboard radios because of electromagnetic noise.”

Allowing a voluntary transition to all-digital AM operation “may help reduce or even reverse these trends since digital broadcasting is generally less vulnerable to interference and provides improved audio fidelity and a wider audio bandwidth,” NAB said.

In addition to better sound quality, all-digital will provide other benefits to listeners, NAB argues. MA3 digital mode allows AM broadcasters to provide auxiliary data such as song and artist information and emergency notifications that include text and images, according to NAB.

Existing analog-only AM receivers would not be able to receive all-digital signals. But NAB says there are nearly 70 million cars on the road equipped with HD Radio reception capability, with that number growing steadily. And any loss of listeners due to all-digital operation migration would likely be mitigated by the fact that so many AM stations now employ FM translators, NAB says.

“The commission points out that more than half of all AM stations now have FM translators, potentially softening the blow of any loss of listeners and serving as an important part of an analog to all-digital transition strategy for AM broadcasters,” the association says.

It said that field and lab tests by NAB Labs (now called PILOT) have illustrated successful operation of all-digital AM radio service. “These tests showed that all-digital AM provides audio quality on par with FM stereo, and acceptable daytime coverage even out to the 0.5 mV/m analog contour of most of the tested pathways.”

[Read a commentary about all-digital by Cris Alexander.]

NAB believes the chances of all-digital AM operations causing interference with analog AM stations “is a lesser concern compared to digital hybrid operations because the former produces fewer emissions at the outer limits of the occupied bandwidth.” But it concedes: “By its nature, the all-digital signal is a stronger interferer to co-channel analog signals than are legacy analog AM signals.”

NAB included in its comments a remedy to complaints against all-digital AM stations from neighboring analog signals. “For example, the station operating in all-digital mode may reduce power or reach some other arrangement with an aggrieved co-channel station.” It adds various technical and regulatory options already exist for reducing or eliminating unacceptable interference caused by hybrid digital stations that should similarly apply to all-digital service.

In addition, NAB supports the FCC’s proposal to incorporate the NRSC-5-D standard into the digital broadcasting rules.

The NAB says the 2020 NAB Show is still on, as of Tuesday, March 10.

A spokesperson told TV Technology that “the show is moving forward as planned.” The association updated its coronavirus update page on Tuesday, announcing that it is “continuing to evaluate the national and international situation carefully.”

The NAB says it is taking its direction from global, federal and local health officials, like the WHO and CDC, which at this time have put no travel notices or restrictions on public gatherings for the U.S.

[Read: 2020 NAB Show: Schedule, Exhibitor Info, Updates]

Concerns over the impact of coronavirus (COVID-19) on large gatherings has prompted a number of cancellations, including SXSW, which was expected to attract several hundred thousand to Austin, Texas, this month. PBS TechCon, which holds its annual gathering in Las Vegas just prior to the NAB Show, also cancelled its event last Friday.

Several high profile exhibitors backed out of the show on Monday, including Ross and Adobe. NAB says that 96% of its exhibitors are still planning to attend, and of the 4% no longer attending, the association claims more than 80% would be coming from China, which has implemented travel restrictions.

“Ross has been at every NAB since 1974 and this has not been an easy decision to take, but we have a clear duty to our employees, our customers and families,” the company announced, adding that is was looking for alternative “virtual” ways to get its NAB Show news out to its customers and attendees.

Adobe said in a blog post: “Over the past few weeks, we have been closely monitoring and evaluating the situation around COVID-19 and have made the difficult but important decision to cancel our presence at the show this year.” Adobe had previously cancelled its summit that was also scheduled to be held in Las Vegas.

NAB is working on ways to both minimize the risk of transmission on the show floor — including implementing a “no handshake” policy — and to add value to in-person attendees remotely.

I’m still a fan of the classic AKG K240s, once a familiar sight in many a radio station, with their open-backed design and rather open sound as well. However, the AKG K275 and AKG K371 headphones reviewed here are closed-back and more in line with modern performers/recordists who like the tight isolation, extended bass and high SPLs of closed-backs.

AKG K275 K275

The K275s offer a round, closed-back, over-ear design and slow-retention foam ear pads. They don’t look like it, but they fold right up for easier transport, with a three-axis hinge and rotatable cups, and they come with a nice cinch-top storage bag. At 295 grams (0.65 pounds), these AKG headphones are slightly heavy in use, but still comfortable because of the soft ear pads. These headphones will only go so small, however, as the headband tension defines fit, so smaller people and those with bald heads might want to try them on before purchase.

The large 50 mm drivers operate at a low-ish 32 ohms, enabling efficient use with a 109 dB SPL/V rating and wide response from 16 Hz to 28 kHz. Sonically, I found the 275s to have a warm high end, with more of a bottom end emphasis and plenty of low-mids, not the carved out middle that is so common. The low end isn’t terribly defined, so I had trouble making mix decisions, but I found that performers liked tracking through them quite a bit. Bassists and guitarists appreciated the full, warm response, even if they weren’t such a hit with vocalists.

The stereo imaging was strong, with a well-defined phantom center, and dynamics were slightly constrained at higher volumes (like most headphones). Although I wasn’t able to mix on the 275s solely, I did find them a useful mix check for excessive low-mids and to make sure that higher-pitched elements were well represented.

The two big steel bands that are the backbone of the 275s seemed amply strong and durable, and the three cables provided (coiled, short straight and long straight) are connected via a nice LEMO connector, ensuring long life and durability.

K371 AKG K371

Even though the 371s are foldable, over-the-ear and closed-back, they’re really nothing like the 275s. Here, the ear cups are oval, with a softer slow-retention foam, and their lighter 255-gram weight (0.56 pounds) makes for a comfier fit. These cans have ear cups on sliding bands, unlike the sliding headband of the 275s, which allows for a snugger fit. Plus, they still fold up (the ear cups and their support arms snap and fold inward).

Once again, we’ve got 50 mm drivers, but this time with pure oxygen-free voice coils (and the accuracy that reportedly brings). These phones have 32-ohm impedance but yield a very efficient 114 dB SPL/V, with an extremely wide frequency response of 5 Hz to 40 kHz.

The K371’s sonic signature is decidedly different from the 275, with a tighter and more defined low-end response, more punch, still a warm top end, and upper-mids that are much more forward. Dynamics and imaging seem comparable to the 275s and sufficient.

I found performers liking these AKG headphones, too, with instrumentalists and vocalists enjoying them, but bassists not so much (nor myself when mixing). As much as I loved the comfort and fit of these phones (I can wear them for hours without fatigue), I never could get over one prominent midrange frequency bump (around 600 Hz) that got in the way of my mix decisions. This response made vocal and upper instrument decisions tough, but I still found the 371s to be a great bottom-end reference checkpoint. Their nicely moderated bass response is well distributed and quite even across the spectrum, providing great insight to bass and drum mix decisions.

The three cables and storage bag complement the 371s as well, making them a good choice for users who wear headphones for very long periods of time, who want effective isolation and comfort, and those who like their guitars/vocals/snares more prominent than their kicks/basses/toms.

Italy has been at the forefront of digital radio adoption in Europe for two decades, with three national and several local DAB+ multiplexes on the air today.

The Plan de Corones site serves Italy’s South Tyrol region, a mountainous area by the Austrian border.

Approximately 83% of the Italian population can receive DAB+ broadcasts today, with well over 150 different transmission sites from the three national broadcasters. These networks stretch from the northern border south through Italy’s famous boot-shaped peninsula — with some networks extending into Sicily and Sardinia.

EVOLUTION

Of the three national services, DAB Italia has perhaps the most interesting history. The network operator, owned by private radio service providers, launched its initial tests in Northern Italy in 1998, and was actively involved in regulatory development for the emerging medium. Those developments stretched into the second decade of the new century, resulting in DAB Italia’s 2012 commercial launch.

The Torcegno site covers the Trentino region not far from the Austrian border.

The technology has continued to evolve and change in those ensuing 13 years — changes that brought new challenges and benefits. Notably, the introduction of a second-generation audio codec in 2007 shifted testing from DAB to DAB+ due to the enhanced service and quality capabilities that the latter offered.

“The launch of the MPEG-4 AAC+ Version 2 codec presented us with a more efficient audio encoding standard,” said Hanns Wolter, technical director, DAB Italia.

“The previous MPEG-1 Layer II standard limited us to around 10 DAB radio services for each multiplex. The second-generation standard doubled that capacity while also reducing the associated transmission costs. It was an important development in efficiency that has allowed us to protect our investments over many years.”

To serve the Piedmont region, a large Kathrein 10-bay, Band III Yagi antenna is top-mounted to the tower. The same tower supports a large, top-mounted Aldena antenna.

Naturally, as with any early digital radio service, there weren’t many possibilities of reaching an audience. “There were no DAB+ receivers in 2007,” he said.

“It took us at least four months to procure a DAB+ receiver for our own tests, and we could only verify the operation with test equipment. We immediately heard the audio quality improvements, and soon followed the efficiency benefits.”

The efficiency largely comes down to the number of transmitters required. “We need 40 to 50 FM transmitters to achieve the same results that we do with 10 DAB transmitters on a single frequency network,” said Wolter. “This really opened the door for commercial DAB+ radio in Italy, because those tests proved we could deliver cost-efficient digital transmissions.”

EARLY INNOVATION

DAB Italia’s efforts have paid off. With more than 120 live transmission sites from the Austrian border south through Naples, Italians with DAB+ receivers — currently estimated at more than 4.5 million — can receive 16 DAB Italia digital radio programs (three other channels are used for testing). Many are broadcast exclusively in DAB+, while others are also available as FM simulcasts.

“We cover much of Italy, but we are still building the network,” said Wolter. “We add between 20 to 30 transmitters a year. It’s a continuous rollout intended for national diffusion.”

That national perspective is mainly focused around road travels. “Italians drive a lot and are often stuck in traffic. Therefore, 70% of Italian radio consumption happens inside the car,” said Wolter.

In the northwest corner near the Swiss and French borders, the Gerdaz site covers the broad Aosta Valley region.

The early rollouts focused on major cities to address the most heavily traveled regions. Italy’s geographical footprint expands over 116,350 square miles, which means there are plenty of open highways, expansive countryside areas, and challenging terrain. Italy’s two mountain ranges, the Alps and the Apennines, are monumental, with the latter running north to south through much of the country.

All of this means that to make a true impact, DAB Italia soon looked beyond the major metropolitan areas. “We sent a strong signal to the automobile industry: We are providing Italy with a network, and it’s time to get DAB receivers into your cars,” said Wolter. “Our tests showed that the performance and propagation were especially good in the valleys, and we were penetrating the more challenging mountainous terrain. We were achieving capabilities that we simply could not do in analog.”

TACTICAL APPROACH

By the seaside in northwestern Italy, the Monte Fasce site covers the Liguria region, including the capital city of Genoa.

The DAB Italia team tries to locate each transmitter site based on what will provide the best coverage, including rooftops and traditional high broadcast towers in cities, and hilltops to penetrate valleys in rural areas.

Regardless of location, each new site involves extensive planning and theoretical studies. “There are a number of hurdles and constraints in an SFN deployment,” said Wolter. “We have to precisely calculate the delays across each transmitter for the receivers to decode the signals accurately. If the signals are outside a time interval of 246 microseconds, the RF interference contributed by the different transmitters will disrupt reception. Staying within that time interval will both influence and limit site selection.”

The site buildouts are simple by comparison. DAB Italia favors simple antenna systems from Kathrein or Aldena Telecomunicazioni, both of which Wolter says are simple to install and control. DAB antennas are approximately half the size of FM antennas, which makes it easier to place and position the antenna.

The network includes a mix of transmitters from six vendors, some of which are no longer in business. The most recent phases have utilized GatesAir S.r.l. (formerly ONEtastic) and Syes transmitters, both based in Italy (GatesAir S.r.l.’s parent company, GatesAir, is located in the United States). Wolter notes that both companies strike the balance of price, performance, and space-efficiency they are seeking as their network grows.

“Over the last years we have supported these manufacturers in the development of their DAB transmitters with the capabilities we needed to operate correctly our network,” said Wolter. “We worked closely with them on the software development side to access information on system performance. An important recent development is the integration of satellite receivers into the most recent transmitters they shipped. That removes the cost of external receivers. They are active listeners and respond to our requests.”

DAB Italia has deployed 15 GatesAir’s Maxiva transmitters since early 2019 covering a range of power levels and network requirements. “The first GatesAir transmitter we installed provides DAB+ service to the city of Verona, but we also have a number of medium-power transmitters and gap fillers.

Most of these transmitters deliver power levels of 100, 250 or 450 W. But we have gap fillers as low as 25 W, and a few higher power systems that go up to 2.5 kW. All have a 40% efficiency rating, and the higher power transmitters reduce energy use by 15 to 20%.”

The multiplexes come into the transmitter sites from eight radio content providers, using a Factum Radioscape system that takes in signals via IP, satellite and fixed radio links. DAB Italia ingests the various contributed signals into the Factum multiplex, which combines and distributes the signals to the various transmitter sites.

“Our system is really a server farm,” said Wolter. “Audio processing is handled by the content providers, and we manage distribution of the finalized signals. The Factum Radioscape system integrated encoders, which leverage Dolby or Fraunhofer audio codecs. Each has a digital audio interface or AoIP.

The DAB Italia network has a mix of transmitters, including GatesAir (formerly ONEtastic) transmitters for recent deployments in Ferrara and Asti.

“We can adapt a broad range of bitrates based on the quality of the originating signal we receive,” explained Wolter. “We rely on our content providers to appropriately process the audio for DAB, which is quite different compared to processing for FM. DAB offers more bandwidth, which means less processing is required. Too much processing will create a loss in audio quality.”

The majority of DAB Italia’s 19 channels are currently encoded at 48 kbps using HE-AAC+ Version 2 coding. Some are encoded with lower bitrates of 32 kbps, while others leverage higher bitrates of 64 kbps.

[Read: 2020 Looks Good for Digital Radio, Smart Speakers]

“It’s an interesting compromise that still results in exceptional audio quality for the broadcast, provided the source signal is pristine,” said Wolter. “You cannot correct a bad source with higher bit rates; the quality will not improve. The listener will just notice the problems more easily.”

DAB Italia leverages the ETI protocol for contribution and distribution, but is looking at EDI for backup streams. “EDI had just been finalized as we began rolling out the network, and the modulators and transmitters at the time did not support it,” he said. “We are looking to roll out a system that will seamlessly switch between ETI and EDI sources, which gives us the option of having either IP or satellite as the backup.”

The Radioscape system includes an ETI output, and additional equipment then converts the signals to ASI before being sent into a DVB-S2 multiplex. The satellite receivers at each transmission site extract the ETI signal before sending the streams into the transmitters. Where older transmitters without integrated satellite receivers are used, DAB Italia leverages external extractors and receivers from 2wcom.

CAREFUL INVESTMENTS

As DAB Italia works with private radio service providers, they are limited to a certain annual budget. That budget is used to manage the rollout of new sites and maintain the existing network.

“We’re funded by FM revenues, which means we don’t have the budget to roll out 100 to 200 transmitter sites a year in a way that public networks can afford,” said Wolter. “It forces us to make thoughtful investments, and it has provided the opportunity to gain experience in building DAB networks.”

This also means that the network operator needs to use existing resources wisely. Therefore, labor and system maintenance require some very careful planning.

“DAB maintenance is a complex subject in Italy, as a large majority of the existing engineering base is not trained for digital,” said Wolter. “It’s mostly a different generation of technicians that have years of FM experience, but don’t quite understand digital radio. It’s very difficult to convince them to take a laptop to the transmitter site.

“But we have found that most DAB transmitter failures are generic — things such as the power supply, or a software issue. The simplest and easiest way is to change out the transmitter at the site and take it back to the lab.”

Wolter notes that GatesAir has reduced the maintenance burden with more modern and clever designs. “It’s almost like a Lego box, especially with their smaller transmitters,” he said. “They have interlocking parts and no cables. These are compact transmitters with separate amplifiers. It also makes for an interesting tunnel coverage solution, which we are now evaluating.”

Wolter expects to significantly expand the network over the next two years, taking the DAB Italia service to smaller cities, towns and roads, one by one. The most recent GatesAir transmitters recently went on the air in Ferrara and Asti, which represents their expansion strategy into smaller cities.

“We will extend highway coverage further, focusing on areas that are underserved,” he said. “Our second step is to install a local transmitter in every major regional or provincial towns. We ultimately expect to have a network of more than 400 transmitters throughout Italy, and to run it at approximately one-tenth the cost of a comparable FM network.

“Italy is closely interconnected with other European realities and we always keep an eye on new technical developments to keep our system at the highest level of reliability and efficiency,” concluded Wolter.

The owner of HD Radio technology, not surprisingly, hopes the FCC will allow individual AM-band stations in the United States to switch to all-digital transmission if they wish.

Xperi said it will work with the broadcast, consumer electronics and automotive communities to push forward all-digital MA3 broadcasting if the FCC adopts the proposed rule. Comments to the commission about all-digital AM (Docket MB 19-311) are due today (March 9). Reply comments are due April 6.

The FCC proposed last fall to allow U.S. AM radio stations to turn off their analog signals and broadcast in the in-band on-channel (IBOC) mode known as MA3. Analog-only receivers — of which there are countless millions — would not be able to receive the all-digital stations; but the growing number of cars equipped with HD Radio receivers would.

[Read a new commentary from Xperi: “Is AM All-Digital Right for Your Station?”]

Xperi told the FCC that HD Radio broadcasting provides many benefits over traditional analog radio, including crystal-clear, static-free sound, multicasting, enhanced metadata — including artist, song title, and album information — traffic services and enhanced digital emergency alerts.

For broadcasters with cost concerns, Xperi says it is prepared to make the transition affordable. “Currently, Xperi offers AM stations a license to use all-digital technology in perpetuity without any initial or ongoing licensing fees.” It noted the cost to upgrade facilities to accommodate all-digital operations will vary by station. “By providing broadcasters with the flexibility to transition if they want and when they want, however, the commission will facilitate a transition driven by market forces rather than regulatory fiat,” Xperi wrote.

[Watch Radio World’s recent webinar “Digital Sunrise for AM,” available on-demand, for an extended exploration of this topic.]

The company addressed concerns about interference: “Because all-digital signals have less spectral occupancy, the potential for interference is greatly reduced as compared to hybrid mode. Moreover, the HD Radio system was designed to operate in a mixed environment of analog, hybrid and all-digital stations, with all-digital signals designed to protect analog and core digital services within their protected contours,” it wrote.

The company also continues to push the FCC officially to adopt the NRSC-5-D standard as the official standard for each digital radio station. “NRSC-5-D is a mature standard that already serves as the de facto standard for both hybrid and all-digital transmissions in the United States,” Xperi said.

Only one AM station, WWFD licensed to Hubbard Radio, operates in full-time all-digital under special temporary authority from the FCC.

The NAB has favored the FCC’s move to adopt all-digital AM.

Two major broadcast industry events have been postponed due to concerns over COVID-19 outbreak.

The 2020 edition of Radiodays Europe has been indefinitely postponed, General Manager Peter Niegel announced in a Monday email. 

According to the Radiodays Europe email, the steering board’s decision was made “after extensive consultation to ensure the health and safety of our participants, speakers, commercial partners and staff.” Niegel cited concerns over travel logistics, crowd safety and other factors related to coronavirus, saying the attendant health risks make “it impossible for Radiodays Europe to hold an event at this time.” This is a significant change from last week’s messaging.

Niegel’s announcement promised that new dates for Radiodays Europe will be announced on the event’s website. It is unclear whether the event will still be held in Lisbon, as originally planned.

Additionally, CABSAT has been rescheduled from late March to Oct. 26–28, according to the event’s website. The event will still be held at the Dubai World Trade Center. 

CABSAT organizers emphasized that the United Arab Emirates is still open for business: “Whilst the UAE remains completely safe for travel, and has deployed the strictest medical and hygiene protocols, we fully recognise that for some specific shows, we have a high majority of key participants significant to the event’s programme that are unable to travel due to restrictions in their home countries.”

The CABSAT update also notes that the postponement was supported by stakeholders and they expect “greater participation” and “more inclusive access” with the new timeframe.

Coronavirus jitters are also affecting events scheduled for the summer and late fall. However, “IBC2020 is proceeding as planned, Sept. 11–15 in Amsterdam,” according to a statement updated March 5. 

IBC planners said, “We are aware of the concerns that Coronavirus (Covid-19) may be causing and would like to reaffirm our commitment to delivering a safe and successful IBC2020. We are monitoring the situation very closely and will take the advice of the relevant international, national, local authorities and agencies to ensure the safety and wellbeing of all involved with our event in September.” 

Organizers noted that they “ will ensure that IBC2020 is fully compliant with all required regulations,“ including those they expect European Union health authorities to publish soon.

The Multicultural Media, Telecom and Internet Council is worried that some broadcasters and state associations are trying to “totally eviscerate, diminish or cripple” enforcement of the FCC’s Equal Employment Opportunity rules. 

Some broadcasters have argued that current rules, “with their laudable goals,” require burdensome paperwork and nonproductive effort, especially at smaller companies; they laid out those arguments as part of an FCC notice of proposed rulemaking.

MMTC recently replied with a 22-page letter from its President Emeritus and Senior Advisor David Honig to Chairman Ajit Pai and the other four commissioners. It says some broadcaster proposals are contrary to the intent of the NPRM.

RESET SMALL-STATION EXEMPTION?

MMTC found “common ground” with broadcasters on certain issues, including the need for the FCC to publicize its EEO whistleblower and anti-retaliation rules. 

But it took issue with the overall tone of comments to the commission. “This proceeding is not about how to totally eviscerate, diminish or cripple EEO enforcement,” Honig wrote. “Instead, the NPRM called for comments on how to improve the current EEO enforcement system.”

The regulations disallow the use of race and gender in hiring decisions, while seeking to ensure that qualified persons, including minorities and women, can learn of and compete on an equal footing for job openings. 

They also require broadcasters to take steps to provide notice of each full-time opening and participate in recruitment initiatives like job fairs and internship programs, along with additional steps. 

According to the FCC, each year it audits the EEO programs of approximately 5% of both radio and TV stations. It also can review compliance at the time of a broadcaster’s license renewal.

According to a summary on the Broadcast Law Blog, the back-and-forth began when the FCC asked for comments on its NPRM in MB docket 19-177, prompted by complaints raised in connection with abolition of the Form 397 Mid-Term report.

Much of the debate focuses on comments from a group of 82 broadcasters, represented by attorney John Garziglia of Womble Bond Dickinson, that submitted joint comments last year. They believe that the FCC’s documentation and paperwork approach to nondiscrimination and employment diversity is not working.

“In the absence of evidence that the current FCC’s paperwork and recordkeeping requirements prevent or reduce discrimination, or increase employment diversity, the FCC should generally direct its regulatory efforts to finding effective ways to achieve the important goals of nondiscrimination and employment diversity,” the group wrote. 

The coalition of 82 broadcasters — some consisting of one or a few stations, others with dozens — titled its filing “EEO Enhancements” but concluded: “If the FCC’s paperwork and recordkeeping requirements do nothing toward reducing discrimination or enhancing diversity, they should and must be jettisoned.” 

But it also told the FCC that its members have “no desire to lessen or diminish the FCC’s quest for diversity in employment, and full and transparent opportunities for all seekers of jobs in the broadcasting industry. To the contrary, [we] believe that the commission can do more to achieve its goal.”

These broadcasters proposed requiring a wide outreach through a nationally or regionally recognized job-oriented website for every full-time broadcast station employment opening, no matter how few employees it has. “The placement of an internet posting for an open position at a broadcast station is something that most stations now do, and requiring it of all broadcast stations is not an undue burden and is an effort that may bring future broadcasters into the now exempted stations.”

The group also proposes to put an end to the consideration of market-based “employment units,” given the abolition of the broadcast station main studio rule, in favor of an examination of a broadcaster as an entire entity. It calls this “a more pragmatic and sensible definition of employment unit.”

“In return, however,” the broadcasters continued, they asked the FCC to reset the small-station exemption for EEO documentation and supplemental initiative requirements. 

“Reduce EEO paperwork for small broadcasters by exempting entities with fewer than 50 full-time employees, which is the number … regarded by the human resources profession as demarcating smaller from larger entities,” according to the filing. 

“DAMNING INDICTMENT”

The MMTC’s Honig responded directly to several comments from the coalition, which he said “expressly advocated heading backward toward less enforcement, less accountability, and more opportunities for intentional discriminators. … Their approach would help no one but the bad apples in their industries that seek to evade accountability for discrimination. Such comments are not responsive to the NPRM.”

Moreover Honig is troubled by the “hostile language” in some filings. 

“According to the 82 Licensees, EEO compliance imposes a crippling resource burden that simply takes away from the important task of broadcasting. There is no evidence to support this assertion.”

Comments by state broadcast associations also caught the attention of MMTC. Associations wrote in a joint filing: “Many of the proposals presented in this proceeding would dramatically increase burdens on broadcasters while at the same time being of both questionable constitutionality and little practical utility in achieving the commission’s stated goals.” 

In addition, the associations wrote, the FCC “has not found a single broadcaster to have engaged in discrimination since the advent of the first EEO rules in 1969.”

The National Association of Broadcasters echoed that theme: “To our knowledge, the commission has conducted tens of thousands of reviews of broadcasters’ EEO programs since the rules became effective in 2003, without one finding of discrimination. This includes random EEO audits, mid-term reviews and license renewal examinations,” NAB commented.

To this line of argument, Honig replied in his December letter: “The fact that an industry contains discriminators, but they never get prosecuted, much less held liable, is certainly not a strong argument for weakening the obviously insufficient EEO compliance program in place now. That is a damning indictment of the agency’s enforcement program. It is simply not the case that broadcasting is the only industry in the nation whose thousands of employers included no racial or gender discriminators for the past 50 years.”

MMTC said it believes its position is bolstered by comments by several individuals including Dr. Jannette Dates, dean emerita of the Howard University School of Communications, Dr. Valerie White, associate professor at the School of Journalism & Graphic Communication at Florida A&M University; and Zemira Jones, president and CEO of the All American Management Group and former vice president of operations for Radio One.  

Another MMTC witness, Robert Neal, president and general Manager of WQID(LP), Hattiesburg, Miss., and executive director of the International Black Broadcasters Association, wrote: “It is absolutely without question that racial discrimination persists in the radio and television industries. I have seen extraordinary well-qualified African American managers, announcers and salespersons get shunted aside when jobs open up. Often they find out the jobs were available only after they were filled,” Neal wrote.

“EDGE OF CONSTITUTIONALITY”

Whereas EEO supporters asked the FCC for more frequent EEO audits, the National Association of Broadcasters pleaded against this.

“Rather, the commission should minimize the unjustified burdens of EEO audits by eliminating audits for small broadcasters,” NAB wrote. It added, “the record [FCC proceeding] lacks support for additional EEO rules and regulations.”

The NAB estimated the cost of an audit in the $3,000 to $5,000 range. NAB also said that the commission “should be wary of imposing more EEO rules, as the current regime already flirts with the edge of constitutionality, and there is no evidence of discrimination in broadcasting that justifies additional regulation or that more EEO rules will actually increase employment diversity.”

The association said additional EEO rules are unjustified and unnecessary.

Fig. 1: Rodent Sheriff mint spray deters pests and smells good too.

Wouldn’t it be nice if you could repel rodents, raccoons, roaches and ants all in one fell swoop? 

Stop by your local big box store and look for Rodent Sheriff Spray (shown in Fig. 1). These pests hate the smell of mint, so your transmitter shelter, ATU or storage shed should stay pest-free — and as a nice bonus will smell minty fresh.

Joe Geerling is synonymous with engineering in St. Louis. Joe ended 2019 by leaving Entercom St. Louis to become director of engineering for the Covenant Network, also in St. Louis. 

Fig. 2: A helpful resource

He dropped me a line recently about his son Jeff. Jeff is a software programmer and wrote a book entitled “Ansible for DevOps” (Fig. 2). 

Ansible is a simple but powerful server and configuration management tool. Jeff’s book will help those familiar with command line and basic shell scripting start using Ansible, to provision and manage anywhere from one to thousands of servers. The subject matter is increasingly relevant as more and more companies get into cloud computing. The book is available from Amazon for under $20.

Jeff is also an avid podcaster. Joe writes that Jeff wanted to “up” his podcasting game and took an old RE20 apart in order to replace the internal foam. 

There are a lot of old Electro-Voice RE20 mikes being dumped by stations because they no longer sound good, or have started to shed decayed internal foam. Perhaps you have one or two on your shelf.  In most cases, as these mikes age, the foam supporting the capsule deteriorates. Although the job to replace the foam is time-intensive, the result is restoring a great-sounding microphone! 

Jeff documented his experience, complete with pictures and step-by-step instructions, on a blog post. Read it here:  https://tinyurl.com/hpt3fux.

I’ve spoken to a number of engineers who have found it difficult to acquire a reliable, versatile FM/AM/NOAA weather receiver. 

The Watch Dog (WD-1) is reliable, versatile and features a real-time RDS decoder, making it a great choice for an EAS receiver. This compact receiver can also be used as a confidence monitor, and even provides an open collector alarm system. If you need contact closures, attach the optional Watch Dog Alarm.

Richard Parker shared a twist on using muffin tins to hold parts when disassembling equipment. 

The Daiso Japan’s Clear Plastic Document Case, Model A4L, is a clear plastic case with a snap-on top. But if you add a Daiso A4 magnetic sheet on the bottom of the tray, steel screws, nuts, washers and other parts stay put. The magnetic sheet is white, and could also serve as a “white board” for brainstorming during other projects.

Shown in Fig. 3, the plastic tray is available from the Daiso Japan online store and also from Amazon for about $10 for two trays.

National German Radio GmbH is launching an international call for applications for the remaining slots of Germany’s first private nationwide DAB+ network.

Erwin Linnenbach is the CEO of National German Radio.

The organization says the platform will potentially reach more than 67 million people when it goes on air. They are also already planning a network expansion.

Antenne Deutschland tasked the Leipzig-based company with market placement of the remaining space. Interested parties can register on its website.

Antenne Deutschland will decide on allocation in June. The service will start in September and run for a 10-year period with an optional extension until 2040. The launch coincides with the international consumer electronics show IFA 2020 in Berlin.

“The new platform will decisively transform the private radio sector in Germany because new national advertising budgets will be triggered by new offers and existing national advertising budgets will be shifted from local/regional toward national radio programs,” said Erwin Linnenbach, CEO of National German Radio.

The main selection criteria will be based on “broadcasting concept and a broadcaster’s expertise and innovative spirit,” he added.

“Our goal is to combine the remaining slots with Antenne Deutschland’s radio programs to create a diverse, colorful family of attractive content – a mix which is economically powerful and will have a considerable impact on listeners and advertising markets.”
