Podcast #201 – A Fantasy FCC Serves the Public Interest

Radio Survivor - Tue, 07/09/2019 - 21:34

A different media world is possible. What if the FCC truly regulated in the public interest, creating policies and services that promoted community voices and civic values? It does happen occasionally, but not often enough.

It’s easy to assume our media system turned out this way because it was inevitable, but in truth it was the result of hundreds, even thousands of decisions, at all levels of government, influenced by multitudes of actors, from major corporations to community media activists. That means there have been, and still are, many opportunities for change, and improvement.

But what would that revitalized FCC look like? Matthew Lasar has some ideas, based upon his years of researching the Commission, going back to its pre-cursor, the Federal Radio Commission, created by President Herbert Hoover, a Republican who opposed privatization of the airwaves and believed in a robust public service obligation. Matthew’s suggestions may not be what you think. We invite you fantasize along with us.

AEQ Netboxes Provide Access to IP

Radio World - Tue, 07/09/2019 - 15:48

LISBON, Portugal — Last May, AEQ provided training sessions on Dante AoIP networks in Lisbon,  Portugal. Since 2016 TSF Radio News has been users of many AEQ Dante-based devices, including a BC2000D router, audio mixing consoles, intercom systems, Netbox 32, Netbox 8 and Netbox 4 AoIP interfaces, etc.

I dropped by to say hello and take the chance to refresh my skills in Audinate’s Dante technology. My curiosity was drawn to a new device called Netbox DSP. The representatives from AEQ explained to me what it does, and I committed to evaluate it in a real test environment. I am happy to work with AEQ; they are always open to my contributions and try to adapt their products to our needs whenever possible.

Netbox DSP is a mixing, distributing and processing audio router. Its most innovative feature is the absence of direct audio inputs and outputs. It is able to receive audio from the Dante or AES67 network and then return it, mixed and processed, to be used in other devices or subsystems.

[Tank FM Transitions to AoIP With AEQ]

It has a basic front panel since control is entirely performed from a software application. The only features are two power indicators for the redundant power supplies, activity LEDs for the primary and secondary Dante networks and, lastly, a red error indicator.

At the back there are AC power supply sockets, Dante AoIP primary and secondary connectors, a fan and four GPIO connectors. When I asked about this fan, AEQ answered that it only starts when the unit is at risk of overheating and that its speed depends on the temperature inside the device.

[AEQ Designs Remote Network Controllers]

The utility of GPIO signals in AEQ Dante devices offers the possibility of transporting them across the network. For example, I can close a contact in the mixing console (GPIO) and this triggers a macro in the audio matrix in order to perform the required crosspoints to put the studio on-air, for instance. At the same time, I can turn on an indicator that informs the operator in the central control which studio is on air.

The unit that I tested was able to mix and route 96 audio channels, but AEQ has versions managing between 64 and 160 input/output audio channels.

It is all controlled from Netbox RTC software, which allows the user to open different work window instances in order to customize the viewing of the different router devices and which lines to control.

The NetBox DSP has great processing capabilities, which can apply to up to 64 audio channels. These include high-pass filters, low-pass filters, band-pass filters, four-band parametric equalizers, compressors, expanders, limiters, noise gate,  delay (up to 10 seconds), audio silence alarm or level metering and test signal generation.

The AEQ Netbox DSP is a unique product in the Dante universe, it offers excellent features with a very limited price. We especially like the high processing capabilities that are included with the unit, and how easy it is to integrate GPIO commands in our IP network using Dante or AES67.

For information, contact Peter Howarth at AEQ Broadcast International in Florida at 1-800-728-0536 or visit www.aeqbroadcast.com.

Love Radio Finds Niche in Shanghai

Radio World - Tue, 07/09/2019 - 03:33

SHANGHAI — Located on China’s Pacific coast, Shanghai is the country’s biggest city with a population exceeding 26 million people; three times that of New York City (8.55 million). It is also a city that loves its music, and no radio station captures that idea more than Love Radio 103.7 FM.

Launched by the Chinese government’s Shanghai Media Group (SMG) on Aug. 8, 2005, this 24-hour advertiser-supported station plays “local Hong Kong/Taiwan/Mainland music, as well as some international favorites from the ’80s and ’90s and a bit of the 2000s,” explained Love Radio DJ Ming Zhang, who broadcasts on the station under the name ‘David.’ Love Radio’s listeners are males and females 30 to 55 years old, who are “mainly intellectuals” with “above average income,” he said. “Their preference is for more ballads and love songs.”

INSIDE LOVE RADIO

Love Radio is one of 13 Shanghai radio stations operated by SMG Radio; a large media group under the SMG managerial umbrella. SMG Radio “is a large media group concerned with broadcasting radio programs and running all the business including exploiting resources that are related to broadcasting business,” said Zhang.

SMG Radio’s other stations include Shanghai Traffic Radio, East Urban Radio, Pop Music Radio (101.7 FM), KFM (98.1 FM), Classic 947, Traditional Opera Radio and Audible Fiction Radio.

The “Love Radio” brand reflects the positive feelings that the station’s music format aims to inspire in its listeners. “Love is a wonderful thing, it unites people all over,” Zhang said. “Being loved by others gives you strength and power, Love Radio wants to play that role through music.”

Love Radio’s broadcast studios are located at No. 1376 Hongqiao Road in Shanghai. The station has 14 DJs working around the clock, and produces four major weekday programs in addition to its other programming.

These are the 7–10 a.m. morning show (hosted by Zhang under the name “Morning Discovery”); the 11 a.m.–2 p.m. lunchtime show; the 4–7 p.m. drive time show; and the 7–10 p.m. Love Radio chart show.

“Our signal is sent via Shanghai Oriental TV Tower, with its height reaching 468 meters,” Zhang told RWI. “The FM transmitting antenna is 320 meters in height. Love Radio’s transmitting strength is 10 kW.”

As for the station’s Shanghai market share? “Love is the No.1 music format radio [station] among the mobile population,” said Zhang. “For the overall rating, it ranks at No. 2 after FM 101.7. Since the market share of SMG Radio is over 98% of the whole, Love Radio’s market share is approximately over 20% among the target listeners (30- to 55-age bracket).”

A LOOK AT MING ZHANG

In Western broadcasting, education isn’t always a top priority for radio DJs. But the same is apparently not true in China; at least where Zhang is concerned. According to his resume, Zhang graduated from Shanghai’s Fudan University; ranked number 159 by “US News & Global Report” in its list of the Best Global Universities. Due to Zhang’s academic achievements in linguistics and foreign literature, he was quickly recruited to work for the Shanghai Foreign Affairs Office after graduation.

Ming Zhang’s listeners join him in studio for a live Love Radio broadcast.

However, it was Zhang’s love of western pop music that saw him become a columnist for “Audio & Video World,” the earliest music magazine published in China after the implementation of the country’s “opening-up” policy in the 1980s. By 1993, Zhang was a guest host on the weekly radio program “Pop Music’s Friend.” This experience spurred him to leave the Foreign Affairs Office for a full-time music DJ position with SMG Radio.

In November 2003, Zhang became host of FM 101.7’s “Tonight At Eight” international pop music program. Three years later, he became Love Radio’s leading morning show host, and presenter of the weekly “Ming Zhang Music Hour” on Saturdays from 9–10 p.m.

Over the years, Zhang has won “Top DJ of The Year” awards three times, along with other honors. He has also been chief commentator for the annual Grammy Awards in Shanghai radio broadcast since 2000; hosting press conferences and meet-and-greet events for the Rolling Stones, Eric Clapton, Celine Dion, Maroon 5, Beyonce, Christina Aguilera, Backstreet Boys, Linkin Park, Usher and Justin Bieber among others.

From 2015 to 2018, Zhang took part in Europe’s International Radio Festival. As part of this event, he aired the specially-produced “East Meets West” radio series during the morning show for his listeners and those listening in via the IRF.

[Read: China Radio International Recommits to Africa]

“East Meets West … introduces classic pop songs with Shanghainese flavor to the international listeners and also broadcasts the interviews that I made in the hosting countries and plays their music to Chinese listeners,” Zhang explained. “For instance, in my first series, I introduced a traditional Alphorn player I met on Pilatus Mountain in Lucerne, because it is the real Swiss sound that I found in this country.”

RADIO REALITIES IN SHANGHAI

There are certainly many cultural differences between China and the West. But when it comes down to commercial broadcasting, radio is radio — and the issues that SMG Group and Zhang face in attracting listeners mirror those faced by programmers around the globe.

One issue that stands out is the effect of streaming media on radio listenership in Shanghai. “The biggest impact comes from the advertising,” Zhang said. “Many advertisers are starting to use streaming media rather than traditional radio as means to reach people for their product.”

On a larger scale, “the biggest challenge we are facing right now is how to maintain our target listeners; especially the young generation, since smartphones are often used to enjoy broadcasts over the internet and podcasts,” he said. “People find it much easier to download music than listen to radio shows.”

To counter this impact, SMG Radio has developed its own radio app. It has also launched training courses to improve the professionalism of its radio hosts and editors, and started working more closely with sponsors to produce more effective ads and achieve better commercial placement.

As well, like broadcasters in the West, Love Radio and its SMG Radio partner stations are promoting the human side of radio to its target audiences. “Our music is played with many stories behind it, which cannot be easily obtained through other media,” said Zhang.

A CONTINUED LOVE FOR RADIO

Between his Love Radio work and his many hosting duties, Zhang is a very busy man. Yet his love for pop music and radio remains undimmed.

Celebrating at the 2018 Love Radio Party (Ming Zhang second from left).

“To share my music experiences with my listeners is the most exciting thing,” he said. “Also, being a radio personality gives me a lot of chances to talk to musicians and all music-related people. Through music radio festivals, I can make friends with many of my counterparts in other countries. To me, music is the universal language to connect myself with the world.”

Looking ahead, Zhang expects pop music to continue to guide his life. “My future plan is to publish a book which highlights many of my exciting experiences with musicians and stars from other countries,” he said. Zhang also plans to open his own “music café,” “where all music lovers can enjoy my CD collections and photo gallery.”

DEVA Broadcast DB4005 FM Radio Modulation Monitor

DEVA Broadcast’s new DB4005 is a third-generation digital FM radio modulation analyzer and monitoring receiver.

The company explains that the system features software-defined radio FM tuner-based signal processing, achieved through “sophisticated” DSP algorithms and that its digital filter precision enables the FM signal to be accurately and repeatedly analyzed with each device.

In addition, says DEVA, the MPX input allows users to monitor external baseband signals, regardless of whether they are from a composite STL receiver/stereo FM encoder, or from an off-air source. “With its incredible processing power, it provides detailed readings of all the multiplex FM signal components, while all measurements are refreshed simultaneously and synchronously,” the company says.

What’s more, the DB4005’s loudness meter can display measurements as defined by both ITU BS.1770-4 and EBU R128 recommendations, thanks to the product’s support of both standards.

This tool, which DEVA says allows operators to monitor up to 50 FM radio stations, supports USB and LAN communication interfaces for remote connection and control. It also provides features such as TCP/IP connectivity, audio streaming, and automatic alerts for operation outside of predefined ITU-R ranges.

FCC Accepting Late Filings of ETRS Form One

Radio World - Mon, 07/08/2019 - 14:05

Broadcasters who may not have met last week’s July 3 deadline for filing their ETRS Form One for the upcoming nationwide National Periodic Test of the emergency alert system are still able to file late, though the FCC’s ETRS team said in an email correspondence that any late filings “should be done right away.”

All EAS participants are required to renew their identifying information annually via the ETRS Form One, with a separate filing for each EAS decoder, encoder or units that combine decoder and encoder functions.

[Read: Wilkins on Prepping for Next EAS NPT]

The nationwide EAS test is set for Aug. 7. On that day, participants will also be required to file ETRS Form Two, which covers day of test information, by 11:59 p.m. ET. ETRS Form Three, covering post-test data will be due by Sept. 23. ETRS Forms Two and Three will become available at the time of the nationwide test.

Filers can access ETRS through the FCC website and must use their registered FCC username associated with the FCC registration numbers. Updates or corrections to the form can be performed 30 days after submission.

Audinate Launches Dante-as-Software Products

Radio World - Mon, 07/08/2019 - 12:14

Digital audio network specialist Audinate has introduced two new software-based Dante products — Dante Embedded Platform, which runs on Linux for x86 and ARM processors, and the Dante Application Library, which allows software developers to integrate Dante functionality directly into Windows and Mac applications.

These new software-based solutions give manufacturers and developers the ability to deploy Dante into products where it wasn’t previously feasible, in ways that weren’t previously possible. Dante can now be deployed in products where either the price point or form-factor made integrating dedicated Dante hardware challenging.

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

Dante as software also provides more flexibility, with the potential to enable new capabilities like Dante being deployed retroactively to products already in the field, the ability to add new features and functions to products on the fly, and the possibility for manufacturers, integrators or customers to configure the number of Dante channels they want for a particular application.

Audinate introduced these new software products in conjunction with several lead customers at the recent Infocomm show.

QSC will begin to deploy the Dante Embedded Platform within the Q-SYS Ecosystem to enable native software-based Dante audio channels. The effort is part of the strategic partnership between the two companies announced earlier this year.

Zoom Video Communications Inc. has teamed up with Audinate to integrate the Dante Application Library into its Zoom Rooms application for video meetings.

Audinate announced a reference design with Analog Devices (ADI) for Dante Embedded Platform on the ADSP-SC589 DSP + ARM processor.

Lee Ellison, CEO of Audinate, comments, “This is an inflection point in the AV industry. The decreasing costs, increasing computational power and improved flexibility of the software approach will enable manufacturers and developers to deploy Dante into a plethora of next generation AV products. The option to go with a software-based implementation will enable OEMs to add Dante functionality to existing products without a major redesign and will drive further growth for networked Dante endpoints.”

Loose Electrical Connections Spell System Failure

Radio World - Mon, 07/08/2019 - 11:32
Fig. 1: Heat from loose wiring connections points to the source of the failure. The blackened plug is a clue.

One of the many maintenance actions we’ve emphasized over the years is that of creating tight electrical connections. 

A contract engineer wrote in to explain how a Crown FM-2K went off the air. The remote control showed that all other readings were OK, and the three-phase backup transmitter in the building was fine. 

At least the station was still on the air! But an 85-mile trip to the transmitter site was necessary.

Once at the site, the engineer needed to do a little bit of sleuthing to find the problem. He began by tracing the AC power feed. The breaker was OK and measured voltage. It was not until he removed the power plug that he noticed the problem (Fig. 1). 

Fig. 2: The outside of the electrical junction box looks fine.

Disassembling the junction box made it apparent that the screw terminal connections had been only marginally tightened. In the few years that the station had been on the air, the connection heated and oxidized until the resistance became high enough to finish it off.

Once the junction box (seen in Fig. 2) was opened, it was apparent that the electrician who installed the outlet wasn’t accustomed to working with stranded wire. Fig. 3 shows how the connections heated and eventually failed. 

Fig. 3: But when screw terminals aren’t tightened firmly, heat and oxidation can cause an off-air failure.

Another licensed electrician subsequently showed our engineer that when working with stranded wire, you should first tighten the connection, but then loosen it and re-tighten it. This process allows all the strands of the wire to deform and settle in a more compact manner. 

Over the years, this tip has served him well.

***

The problem of overheating and the failures it can cause can be diagnosed using a relatively inexpensive infrared detector/camera. There are a number of expensive standalone IR models, but if you’re shopping in the $200-$300 price range, you may want to consider a smartphone solution. 

Manufactured by FLIR or SEEK Thermal, these smartphone accessories are available from Amazon. 

They display temperature on the smartphone screen using a color gradient. Blue images are cool; yellow, orange or red indicate increased heat. 

Imagine being able not only to spot loose outlet wiring or circuit breakers about ready to fail, but also to identify loose coil clips or overheated capacitors in an AM array or loose elbow connections or junctions inside rigid transmission line.

Contract engineers may want to consider this addition to their arsenal of test equipment, offering analysis to clients for a fee. An annual thermal inspection would be good practice for all stations. And for liability protection, it would be prudent to use a licensed electrician to affect repairs uncovered by your inspection.

Spotting potential heat-related failures before they occur can save thousands of dollars — not only in repairs but in air time lost when a failure occurs in a critical equipment.

***

Every so often we get a neat tip from the folks at Platinum Tools. This company is well known for its Ethernet cabling and testing products. Their most recent release is a compact and handy RJ45 connector tester. 

Ethernet cables, especially the eight-pin variety terminating in RJ45-style connectors, can come in enough varieties to make their termination particularly confusing. The VDV MapMaster 3.0 is ideal for anyone doing a lot of Ethernet cable work. 

In reviewing their website, I discovered it is a wealth of cabling know-how. In addition to a blog and white papers, you’ll find how-to videos on cable prep and wiring subjects.

Fig. 4: Do you know what these are, and how they were used in both radio and TV stations?

One of the neatest finds, however, was information on a free wiring tool. This tool comes with every piece of Cat5/6 cable and can be used to separate the individual wire pairs. What is it? It’s the piece of twisted pair cable jacket that you remove to expose the four pairs prior to terminating! 

Using the “tool” is simple: Just slip it over each individual wire pair, one pair at a time; then as you slide the jacket over the pair, twist it in the opposite direction of the pair’s twist. Keep turning as you pass the sleeve over the pair, all the way down to the cable jacket. 

To improve the performance, the folks at Platinum Tools suggest that you take your scissors and cut the end of the tool’s jacket at a 30-45 degree angle. The angled end makes inserting the wire pair easier.

***

OK young’uns! Take a look at Fig. 4 and let me know if you can identify what these are. There was a time when they were commonplace at nearly all radio and TV stations. (It’s not fair asking anyone over 30!) My email address is below.

Get Groovy With New Gear: Summer of Products 2019

Radio World - Sun, 07/07/2019 - 10:52

It’s new equipment season again!

Radio World’s annual feature is all about new gear that has come onto the market in recent months, especially during spring convention season.

Check out the next installment of broadcast goodies.

WorldCast Audemat RDS Encoder

The WorldCast Audemat RDS Encoder is built on the company’s FMB80.

The RDS Encoder carries the expected RDS/RDBS tools (e.g. artist name, song titles, traffic message, EAS, Radiotext, etc.). But looking forward it adds an MPX-over-AES digital audio function. Furthermore, it can insert the encoding directly into the digital chain. It is also compatible with the latest RDS Edition 2018 standards (IEC- 62106-1 :2018 to IEC 62106-6:2018) and upcoming RDS2 standards. WorldCast notes, “RDS2 will allow broadcasters to send more information (such as pictures) through the FM signal by adding three subcarriers to the MPX/composite signal.”

As a WorldCast product, it is conversant with the company’s ScriptEasy Apps and Manager for programming, control and management. It is fully networkable and remote controllable.

There’s also an onboard tuner for immediate monitoring. WorldCast’s Manager software can be used to operate the RDS Encoder remotely.

Axia Audio iQx Console Axia iQx

The Axia Audio iQx is designed with AoIP in mind, all wrapped in a single package.

Telos Alliance VP of Sales, Support, and Marketing Marty Sacks said, “Axia iQx suddenly opens up the world of AoIP and Axia capabilities to more people by utilizing existing network resources and eliminating the cost of an outboard mix engine.”

It will be available with 8–24 100 mm sealed plastic-conductive faders. It also offers three-band EQ and multifunction soft key per channel. According to the company, the talkback and mix-minus system offers flexible routing for sources. The iQx can be operated remotely via a web interface.

As a Telos Alliance product, there are telco/hybrid options available. In addition, native Livewire+ support makes the iQx compatible with other Telos Alliance equipment on a network. It is also AES67 and SMPTE 2110-30-compatible.

Nautel NX AM Digital Transmitters Nautel NX

Nautel has an added a nifty feature to its NX AM transmitter line: digital AM transmission.

Nautel head of Marketing John Whyte said, “Although all-digital AM operation currently requires an experimental license, we and others feel that this is an exciting direction for the AM band and Nautel is ready to support broadcasters as they move ahead with their plans.”

Whyte added, “Its digital modes provide the precision needed in the spectral mask as well as the in-band signal quality required for digital features such as User Experience metadata. NX transmitters, combined with our digital-ready importers and exporters such as HD MultiCast+, make it easy for AM stations to adopt digital transmission.”

DEVA Broadcast DB4005 FM Radio Modulation Monitor DEVA DB4005

DEVA Broadcast’s new DB4005 is a third-generation digital FM radio modulation analyzer and monitoring receiver.

The company explains that the system features software-defined radio FM tuner-based signal processing, achieved through “sophisticated” DSP algorithms and that its digital filter precision enables the FM signal to be accurately and repeatedly analyzed with each device.

In addition, says DEVA, the MPX input allows users to monitor external baseband signals, regardless of whether they are from a composite STL receiver/stereo FM encoder, or from an off-air source. “With its incredible processing power, it provides detailed readings of all the multiplex FM signal components, while all measurements are refreshed simultaneously and synchronously,” the company says.

What’s more, the DB4005’s loudness meter can display measurements as defined by both ITU BS.1770-4 and EBU R128 recommendations, thanks to the product’s support of both standards.

This tool, which DEVA says allows operators to monitor up to 50 FM radio stations, supports USB and LAN communication interfaces for remote connection and control. It also provides features such as TCP/IP connectivity, audio streaming, and automatic alerts for operation outside of predefined ITU-R ranges.
