CLOUD, Minn. — St. Cloud is ranked as market number 187 by Nielsen. But for those of us at Leighton, it might as well be market #1. This is home to our six stations and the headquarters for Leighton Broadcasting, which owns stations in six other markets in Minnesota and North Dakota. 

As a college town, the population of around 70,000 skews mostly on the younger side. There are around 75 stations that can be picked up on the dial here, and competition for listenership can be fierce, especially for our top 40 station KCLD(FM) 104.7. 

INSTALLATION

A few years ago, we installed the Wheatstone X3 FM audio processor on KCLD and have been pleased with the performance. KCLD is known to draw a large audience, billed as the most listened-to station in central Minnesota. We regarded the X3 as the best processor on the market at the time, until Wheatstone came out with the X5. 

We had heard about some of the new X5 advancements — better highs, in particular — and in July 2019, we decided to take it out for a test drive. 

PROCESSING

The unit arrived on a quiet weekday. We know our way around Wheatstone processors, having owned X1s, AM-55s, FM-55s and, of course, the X3. But we immediately saw that the X5 was different. It is probably the company’s most complex processor yet, although the UI is surprisingly easy to navigate. Within a half hour, we had the X5 up and running and our settings dialed in for the most part.

Then we started listening. We had heard about the X5’s new LimitLESS clipper, that it was an innovative approach to clipping and HF pre-emphasis that lets you turn up the highs while controlling peaks. But we were in no way prepared for the actual difference it can make on-air. Suddenly, the high-end was very transparent, much more transparent than anything in the market. We were listening to a much wider, fuller sound and most incredible, we couldn’t detect any additional IM byproducts as a result of processing. 

We drove around and listened to it in our homes, cars and everywhere, including the overheads at the gas station. 

This thing really kicks it up a notch or two on the dial. Also impressive is the processor’s automatic logger feature, which logs every change to the unit, from remote log-ins to audio failover to preset changes. That feature will come in handy for troubleshooting and for dayparted presets, for example. 

The X5 exceeded our expectations. The official stamp of approval came when we not only purchased the X5 for our top 40 station in St. Cloud, but also additional X5s for several other stations in this and other markets.

Mike Kerken

Crawford Broadcasting’s Detroit cluster has a new market chief engineer. Mike Kernen took on the role earlier this week. 

Crawford Detroit consists of WCHB(AM), WMUZ(AM/FM) and WRDT(AM).

Prior to this appointment, Kernen served as director of engineering for Beasley Detroit (formerly Greater Media, which Beasley acquired in 2016) for three decades. 

Before joining Greater Media, Kernen served as an assistant engineer for Ron Rose Productions of Southfield, Mich., after training to be a radio/television broadcast technician at the Specs Howard School of Media Arts, according to Kernen’s LinkedIn profile.

“Crawford is excited to have this very capable and experienced engineer leading our technical operation in Detroit,” Crawford Director of Engineering Cris Alexander wrote in an email announcing Kernen’s designation.

Fox News Radio is one of many U.S. broadcast organizations now “working from home.” It was not a sudden decision.

“We had been monitoring the spread of the coronavirus and continued to enforce cautious and prudent measures across our entire business,” said Vice President John Sylvester. “We began to take additional steps to ensure programming continuity throughout our platforms late February into early March. Our planning was always for the worst-case scenario and unfortunately, we needed to implement a large portion of remote actions for each platform. Right now we have close to 80% of our staff working remotely daily.”

Depending on their job, each staff member has been given remote access to Adobe Audition, Amazon Workspace, Slack, Zoom, iNews for writing and editorial newsgathering, and VPN access to the broadcaster’s ENCO automated audio systems, plus various other tools and software applications. All audio feeds are sent to and managed by the company’s network operations center in New York and backed up in Washington, using a cloud-based platform that gives everyone access to the content in real-time.

“Our network radio reporters and anchors are spread out through the country in LA, Chicago, Miami, Washington, New York, New Jersey, Connecticut, Pennsylvania and London from home locations, with a large portion designated with Comrex Access units along with headset microphones,” Sylvester said. “Also, we supplied our teams with additional Blue yeti microphones for stories to be filed and uploaded.”

Roy helps out with Guy Benson’s remote work.

Host Guy Benson is one of many employees creating remote content for the Fox News Radio Affiliate News Network, Fox News Headlines 24/7, Fox News Podcasts, Fox News Talk and associated online platforms during the pandemic. They are doing so using laptops, internet access, and BRIC-Link, Comrex Access and Tieline IP audio codecs.

“We moved to broadcasting from my house the third week of March,” Benson told Radio World. “We are mostly live, with some segments and guests pre-taped. The White House Coronavirus task force briefings often start during our final hour, so we’ve been monitoring those and sometimes taking portions of it live.”

“I’m just feeding my voice to New York, where our technical producer mixes all the elements,” said Benson. He’s doing his show using “a simple Tieline machine, a sportscaster-style headset mic, and my laptop.”

Fox News Radio’s “working from home” solution is an evolving “work in progress” for this broadcaster. “We look at best practices and procedures so we can continue producing the most reliable news products and services for our affiliated stations, listeners and partners across the country,” said Sylvester. “As we all experience this pandemic globally, we will continue giving the latest news, information, and entertainment to our audience, while providing some comfort as our country and world move forward.”

Meanwhile, broadcasting at his house is working for Guy Benson, even if his only colleague is his dog Roy.

“Doing the show from my own home is convenient and comfortable in several ways, but I miss being at Fox with my colleagues,” said Benson. “The shift isn’t impacting the quality of the content, but it certainly feels more isolating. I’m talking to myself in a room for three hours every day, which has required me to adjust in order to keep my energy and focus high.”

The post How Fox News Radio Is Working From Home appeared first on Radio World.

The COVID-19 crisis has forced many broadcasters to send their employees home, minimizing infection risk to vital employees while keeping programming, engineering, sales and back office functions in service.

This approach is a responsible ad hoc response to COVID-19, but it doesn’t address a long-term issue: How can broadcasters ensure that their facilities remain virus-free or at least as minimally contaminated as possible?

The answer to this question is disinfection: Using cleaning techniques developed for schools and other institutional settings, broadcasters can kill COVID-19 and other threats that may be on their premises and equipment today or be brought in by employees and clients tomorrow.

The information in the following article explains how to achieve this goal. It is drawn from various sources, including a detailed and helpful webpage hosted on CloroxPro.com. 

CLEANING IS ONLY THE FIRST STEP

The road to disinfection starts with cleaning, namely removing obvious surface dirt and grime from surfaces, equipment and floors. It ensures that germs are not hidden in dirt or organic matter from the disinfectant when it is applied. 

As a result, broadcasters need to proceed with their existing cleaning regimes, but they must do more, including keeping food and drinks out of control, production, office and engineering spaces as much as is humanly possible. Since on-air talent often needs to refresh their parched throats, liquids should be allowed in reusable water bottles. But the days of eating lunch over the console have to end.

Warning: Once something has been cleaned, it has to be rinsed to remove the cleaning solution so that it does not interact with the disinfectant. Otherwise, toxic gases can occur. For instance, when an ammonia-based cleaner interacts with bleach, it can produce deadly chloramine gas. Similarly, mixing vinegar and bleach can create toxic chlorine gas.

DISINFECT AFTER CLEANING

After surfaces have been properly cleaned, it is time to disinfect. This means using the right cleaning fluids to do the job, such as CloroxPro and similar bleach-based professional products, Lemon Quat (Quaternary ammonia) and Virox 5 liquid/wipes (accelerated hydrogen peroxide).

The secret of using these products is time: Liquid disinfectants have to be left on surfaces for a certain length of time and then wiped away for the germs to be killed. A case in point: The free downloadable disinfection chart offered for CloroxPro and Clorox concentrated bleach products specifies a wait time of five minutes before rinsing. 

Once the disinfectant has been applied, it will have to be rubbed into the surfaces to ensure proper distribution. To minimize wear and tear on cleaning staff, try handheld surface scrubbers.

Remember: The staff who apply disinfectant will require gloves, eye shields and breathing protection. In some cases, protective clothing may also be needed; check the manufacturers’ labels for information before usage.

WIPE, DON’T SPRAY

Disinfectants need to be applied using reusable, washable microfiber cloths or disposable paper towels/wipes, not sprayed. Spraying disinfectant can dislodge germs from surfaces and put them into air. This can lead to these germs contaminating already-disinfected areas and being inhaled by cleaning staff and others in the immediate vicinity.

The only exception to this rule is when the entire area can be safely disinfected at once. When this is the case, a spraying option like the Clorox Total 360 System with electrostatic spray gun can be used, without the need for rinsing afterwards. Electrostatically charging the bleach droplets (and firing them using compressed air) ensures that the spray will cling to all surfaces consistently for maximum disinfection power. 

WHAT ABOUT COMPUTERS?

Electronics including computers don’t take kindly to having cleaning solutions dumped into their circuits. 

In many cases, products like Clorox Disinfecting Wipes and Lysol Disinfectant Wipes can be used for disinfection wipe downs — but only after broadcasters have verified this assumption with equipment manufacturers (who may have their own products and procedures to suggest). As well, the equipment needs to be powered off first.

In a pinch, rubbing alcohol on microfiber cloths can be used to computer keyboards, mice and touchscreens, but only after this assumption has been checked with equipment manufacturers. Again, turn off the device first and use liquids sparingly.

FINAL POINTERS

Disinfection is just the beginning. Wherever possible, broadcasters need to do whatever they can to minimize the risk of COVID-19 infection.

 A case in point: At iHeartMedia, before staff was dispatched to work at home, “we gave staff their own removable foam microphone covers, for use in the studio,” said Charles Wooten, director of engineering and IT in Panama City, Fla.. “We also kept gallons of hand sanitizer everywhere and encouraged everyone to maintain social distancing at all times.” Whenever radio returns to “normal,” it seems likely such practices will be a standard part of everyone’s operating procedure.

As well, you can hire outside cleaning companies with the expertise and equipment to disinfect broadcast facilities and equipment properly, using electrostatic spraying and steam cleaning machines.

“Once the full disinfection has been down, stations can do maintenance themselves to keep germs down,” said Reuven Noyman, owner of NYC Steam Cleaning in New York City. (One of his disinfectant products, Noroxycdiff, is used by hospitals to kill the C.Diff virus in just two minutes. It also works on COVID-19.) 

“We recommend keeping a sign-in logbook in each room, by the way, so that management can see who’s been using the space in case an outbreak occurs.”

Attorney Richard Hayes sent a letter last week to the FCC’s Enforcement Division asking that the FCC suspend EEO Public File Reports and Responses to Audit Requests. He also has called for the commission to suspend collection of regulatory fees. Radio World asked him to comment on his latest request.

We have no choice but to embrace the idea of thinking outside of the box because they took the box away. It’s not business as usual, and it won’t be for a while. We need to reinvent what we are and what we do, especially during the next six months.

Many businesses are closed and some may never re-open, unless this economy reopens, soon. It’s purely Darwinian; the strong survive while the weak perish. None of this is our fault, yet we are forced to live with the consequences. Small businesses, the lifeline of the American economy and the American radio station, will not re-emerge as quickly as larger enterprises.

So we have a choice: Do we wait for the economy to return or do we invest our time and considerable creative energies in building our businesses for the future? I suggest that we all look toward the investment opportunity which stares us right in the face. I’ll dive deeper into this idea in a moment.

We have no choice but to embrace the idea of thinking outside of the box because they took the box away.

Broadcast attorneys are in no better shape than the broadcasters they represent. If radio station owners don’t make money, they are not very entrepreneurial and are less likely to make improvements to their facilities. Ergo, the lawyers don’t make any money, either. This is trickle-down pain which everyone in the economy is experiencing.

Station owners are not focused on FCC compliance when the threats to their businesses are existential. Consequently, I have some time on my hands. Instead of sitting on my hands and treating this crisis as an excuse to work in the garden, I thought my time would be better spent finding ways to help eliminate some regulatory expenses and compliance issues that broadcasters don’t need, right now.

I’ve been in the radio business since I was 14. This is my industry. This industry is worth protecting. I want to use this time to help make life a little bit easier (and affordable) for the people who keep this industry going, every day. 

I had a good meeting with the staff of Indiana Congressman Jim Banks (R-Indiana 03), on Friday, who has promised to help us find a way to try to eliminate the 2020 Mass Media Regulatory fees in September. I also wrote to Sen. Susan Collins’ office to elicit the support of my own Senator.

The only way to eliminate the 2020 regulatory fees is to temporarily amend the Communications Act. Jim Banks’ office is looking into this and will meet with member of the Energy and Commerce Committee to discuss the proposal. It is hoped that such an amendment to the Communications Act could be added to upcoming stimulus legislation.

ANOTHER IDEA FOR THE FCC TO CONSIDER

Last week, I also wrote a letter to Lewis Pulley, the chief of the equal employment opportunity division at the Federal Communications Commission. I suggested that it would be appropriate to suspend all EEO Public Inspection File Reports, suspend all responses to EEO audit letters and suspend all requirements to recruit or keep records.

Aside from the fact that the EEO program is a complete waste of time in a booming economy, it is a totally pointless exercise when there is no economy. Is this really a good time to host a social-distancing compliant job fair? We can’t keep all the employees we need on payroll, so does it make any sense to widely recruit for jobs which don’t exist? Is this really a great time to entice applicants to work in the radio business?

The FCC needs to suspend this program for the rest of 2020 and, perhaps, beyond. It is a pointless, time-consuming, bureaucratic, make-work program which cannot demonstrate that any of its policies have had any measurable effect on preventing discrimination. Besides, whom at the station will have the time to fill-out all of that meaningless paperwork? When our business is on a respirator it probably isn’t the best time to ask us to jump through hoops.

In the weeks ahead, I’ll be looking at other areas where rule suspension makes sense during this crisis. If you have any ideas, I would like to hear them.  

Now, about that box which was taken away and the investment opportunity it presents. I will sum it up, this way: If you can’t make money…make friends.

My client in Hawaii will auction rolls of toilet paper on the air. The highest bidder will walk away with 1,000 sheets, one whole roll, of brand new toilet paper! All auction proceeds will go to first responders. It will sound fun on the air, it will make some money for the first responders and it makes friends.

Another station airs the Pledge of Allegiance several times each day and this is sponsored by a local power company. A station down south airs the National Anthem twice a day and sells tasteful adjacencies.

These efforts bring people together. Most stations are offering bonus spots (just don’t call them bonus spots or it could mess up your political lowest unit rate), and this helps struggling businesses. There are a lot of examples, and you have probably done a few creative things, yourself. Here are a few more ideas.

CREATIVITY FOR A CAUSE

It’s entirely likely that your salespeople are bored. It’s time to mobilize them in a slightly different direction. First, make a list of the top ten charities and non-profits in your community. These big charities are run by the business leaders in your community. They donate time to these causes and charities are under the gun now, too. Have your salespeople contact the heads of these charities and have them work up promotions to showcase the charity on the air. Do remotes where appropriate. Be visible with each charity.

Coming this spring are a number of opportunities: 

• Mother’s Day. Interview new moms and dads and have them tell you all about the great experience they had at the hospital during the birth of their new baby. Interview hospital staff and members of the hospital board. Father’s day is another opportunity to do something similar. 
• Cancer Survivors Day. Record interviews for later playback about the work the local cancer center has been doing and how survival rates have improved over the years. Interview the board members and cancer survivors. 
• Breast Cancer Awareness. Get behind this but make sure you speak with the organizers and the the board members. Put these people on the air.
• Memorial Day. Memorial Day celebrations and remembrances are organized. They don’t just happen. Local business leaders organize these events. Put these business leaders on the air to talk about their efforts, made especially difficult during these crazy times.

Oh, but it won’t work with my format! Your format, right now, has about as much integrity as your rate card.

Remember, the board members who run these charities own car dealerships, food stores, department stores, fast-food chains, hospitals, banks and distributorships. You help their charities, by putting their feel-good stories on your air, and the board members will listen to your station. Other listeners will tell these board members that they heard a lot of good things about the charitable organization on your stations.

What should you expect from doing this other than a warm, fuzzy feeling? You will get buys. You will get buys you have never had. Your salespeople will have developed relationships with the movers and shakers in your communities, through their charities. These community leaders and business people will be much more inclined to hear your sales proposals when the crisis is over because you were there for them when they needed you. They know your station gets results because they experienced those results with your charitable assistance efforts! Win-win. 

For now, conserve your cash, apply for the government loans and please contact the office of Congressman Jim Banks and ask him to please do everything in his power to suspend the 2020 Mass Media Regulatory Fees. Also, send an email to Lewis Pulley at the FCC Lewis.Pulley@fcc.gov and ask him to suspend the EEO rules for the reminder of 2020. 

Good luck, and remember, it’s a great life. (If you don’t weaken).

LONDON — The Covid-19 pandemic has caused radio listening to peak, but at the same time we’re hearing alarming reports from broadcasters about the huge loss in revenue being faced by many.

Bernie O’Neill addresses the audience at the WorldDAB General Assembly.

The presence of DAB+ has nonetheless remained constant, with its place as the core future platform for radio reflected in the many ongoing developments in major European markets.

Highlights include Germany’s plans to launch a second national commercial DAB+ multiplex, France’s ongoing preparations to launch national DAB+ services, and in the UK the announcement of a major program for licensing small-scale DAB.

We’re seeing some interesting developments in several newer markets too, including Sweden, Austria, Czech Republic and Poland.

DAB+ developments are not just limited to Europe though, with broadcasters in Africa and Asia also launching new DAB services, reflecting the increasing interest in DAB+ on a global scale. This long read provides an overview of the more significant developments we’ve seen across Europe and beyond over recent months.

GERMANY — 18 NEW NATIONAL DAB+ CHANNELS

The planned second commercial DAB+ multiplex will reach 83% of the population with up to 16 new national radio stations. The EECC directive has been successfully transposed into national legislation, covering also consumer receivers capable of displaying a station’s name. 54% of new cars sold in Germany in 2019 were equipped with digital radio — a 34% increase compared to 2018.

FRANCE — NATIONAL DAB+ MUX ON THE WAY

France is in the process of rolling out national DAB+ services and the country’s current legislation on digital radio is being amended to align with the EECC directive. The new regulation will require new cars sold across the country – as well as a number of consumers receivers – to include broadcast digital radio.

SWEDEN — RENEWED INTEREST in DAB+

In February, Bauer Sweden announced they plan to launch 10 DAB+ digital radio services reaching 40% of the population, saying they see DAB+ as the natural step to future-proofing and developing radio for listeners. In November 2019 the public broadcaster — Swedish Radio — submitted an application for a national DAB+ license for the period 2020-2025 for 10 channels.  Back in June 2019 the commercial group NENT had already announced the expansion of their existing national DAB+ network and their plans to launch more new channels.

U.K. — NEW NATIONAL AND LOCAL DAB LAUNCHES

The UK has seen a significant increase in the number of listeners on DAB / DAB+, where three national multiplexes host over 50 commercial stations, of which 20 are now on DAB+. The UK government is conducting a digital radio and audio review to examine future trends and consider how radio should adapt to changing listening habits. This month has seen the launch of a new national DAB station with Global’s Smooth Chill, while the regulator Ofcom set out licensing plans for small-scale DAB.

ELSEWHERE IN EUROPE

In Switzerland, DAB+ listening figures have now surpassed listening on FM, as the country prepares to switch off FM services no later than the end of 2024. All stakeholders are working together toward the planned DSO and planning is underway for a comprehensive DSO communications plan.

In Norway, radio listening has returned to similar levels as before FM switch off. By February 2020, DAB’s weekly reach was 86-88%, and 75% of people have at least one DAB+ radio in their home, while 58 % have a DAB radio, line-fit or adapter in their car.

Italy was the first country to introduce regulation mandating all new receivers (consumer and automotive) to include DAB+ from January 2020. New vehicles produced before January 2020, which are not factory-fitted with a DAB+ receiver can only be sold up to 21 December 2020. Italy has three national and over 20 local DAB+ multiplexes on air, covering over 83% of the population.

In Belgium, following the launch of regular DAB+ services in Flanders in 2018, French-speaking Belgium launched regular services in November 2019. The official marketing launch at the end of 2019 had a significant impact on listener awareness, receiver sales, radio listening reach and share. Consumers’ increasing interest in DAB+ radio – particularly among 25-44 year olds – means it is now the only growing radio listening platform in the region.

In The Netherlands, discussions are taking place regarding the potential launch of a new national multiplex in 2021, while DAB+ receiver sales continue to grow. The country is also working on transposing the EECC directive into national regulation.

Austria launched national DAB+ services in May 2019 and major broadcasters and industry bodies have joined forces to petition for the introduction of regulation to bring Austria in line with the EECC directive.

In Spain, some regional governments — including Asturias, Navarra and Valencia — have urged government to implement legislation on the deployment of DAB+, while in Portugal, some commercial broadcasters have shown interest in launching DAB+, with key stakeholders closely monitoring the development of DAB+ digital radio taking place elsewhere in Europe.

DAB+ developments continue in Eastern Europe. In Czech Republic, a national DAB+ multiplex reaches 80% of the population. Poland is also stepping up the expansion of its DAB+ network, with new multiplexes planned for Warsaw, Gdansk, Krakow, and Poznan. DAB+ services have recently launched in Slovenia, Croatia and Serbia.

BEYOND EUROPE

In Australia, all major cities are already serviced by DAB+ digital radio. There are approximately 400 DAB+ stations on air in the country, and over 73% of new cars now come equipped with DAB+, with commercial radio stakeholders across the country now calling on Federal Government to increase spending in order to further accelerate the rollout of DAB+.

Thailand and Vietnam have ongoing significant DAB+ trials, in Bangkok, Hanoi and Ho Chi Minh respectively.  In Tunisia DAB+ was launched in 2019, now reaching 51% of the population, while in Algeria, a DAB+ trial launched in 2018 reaches two thirds of the capital city Algiers’ population.

Radio Marti began Digital Radio Mondiale (DRM) shortwave transmissions on Feb. 4. Part of the U.S. Agency for Global Media (USAGM), Radio Marti broadcasts news and other programs to Cuba. The DRM shortwave transmissions are from USAGM’s Greenville, North Carolina, site.

Gary Koster, USAGM’s broadcast radio technician, Gerhard Straub, USAGM director of broadcast technologies division, and Macon Dail, USAGM chief engineer at Greenville stand in front of the transmitter and other equipment being used for the DRM transmissions.

USAGM has transmitted in DRM before. There were some transmissions from Briech, Morocco, in the early 2000s. Greenville tested DRM in 2009 in partnership with what was then known as HCJB Global Technology. So why are they back now after an absence of over a decade?

“We want to experiment a bit with different modes and services available on DRM. We also want to help push the development of low-cost receivers and the best way to do that is to put some transmissions on the air, explains Gerhard Straub, director of USAGM’s Broadcast Technologies Division.

An RFMondiale reference receiver is shown with a Transradio DM0D3 DRM exciter and a RFMondiale LiveWire audio router. The large screen is the user interface for a 1RU content server situated behind the screen.

Greenville is using a Continental 617-A transmitter, along with a Transradio DMOD3 DRM modulator and RF Mondiale RFMondial content server. The antenna is a rhombic aimed at 174 degrees. The average power on DRM is 5,000 W. The schedule is daily from 1700–0200 UTC on 7345 kHz.

The Radio Marti broadcasts are in xHE-ACC, the latest and standard DRM codec. “We need the lower bitrates because we are running pretty low power and we are trying to keep the signal robust,” explains Straub.

Although these are regular transmissions, USAGM is making adjustments along the way. The first few days tests consisted of two audio streams, with Voice of America in English in addition to Radio Marti. Now Radio Marti is the sole audio service. The transmissions are using the text box and there are plans to transmit images (MOT Slideshow) and Journaline, an RSS type feed.

For the time being, Greenville will be the only USAGM site broadcasting in DRM.

As for Greenville, “There is no definitive time period for the transmissions. We will continue the transmissions until we need to devote resources to other projects or feel we have achieved what we needed,” said Straub.

Hans Johnson has worked in the shortwave broadcasting industry for over 20 years in consulting, frequency management and sales.
