Nielsen has just released its PPM Audio Software Encoder for FM stations, allowing more broadcasters to move away from a hardware-based audio watermarking process.
“The release of the PPM Audio Software Encoder for FM stations follows the successful completion of a live field evaluation in the March and April measurement periods,” the company wrote in a note to clients.
It had already released the Audio Software encoder for AM stations earlier.
It says the software encoder allows a station to perform its PPM encoding in products from audio processor manufacturers, “enabling opportunities for cloud-based broadcast operations, reduction of rack space in your facilities and simplification of your station’s workflows.”
The company has published a list of certified vendors that includes Orban, Telos/Omnia and Wheatstone products.
In a recent commentary in Radio World, Nielsen Audio Director of Product Management Nick Mannion, wrote: “We took the PPM encoding algorithm (Enhanced CBET) out of the hardware that it lives in today and made it available in the form of a software development kit (SDK). This SDK is then made available to industry participants enabling them to integrate PPM encoding into their products.”
Once an integration is complete, he continued, Nielsen works with the manufacturer of the product to perform a certification process. “This … ensures that the PPM encoding generated by the manufacturer’s product meets all of Nielsen’s encoding quality standards.”
Nielsen plans to expand its PPM Audio Software Encoding to include digital streams later this year.

Digigram introduced the Iqoya X/Link-MPX codec, intended for delivery of an FM MPX composite signal to one or several transmitter sites.
“Currently, most of the studio-to-transmitter links for FM transmissions rely on the transport of the baseband audio signal over IP networks,” the company noted in its release. “This requires the FM composite MPX signal to be generated at each transmitter site with devices such as sound processors and RDS encoders.”
[Check Out More Products at Radio World’s Products Section]
It cited growing demand for the transport of the MPX signal to be generated at the studio, “since it will help reduce the number of required equipment at the transmitter sites, optimize the global power consumption and maintenance costs.”
The Digigram X/Link-MPX supports analog MPX and digital MPX AES192, allowing analog-to-analog, analog-to-digital, digital-to-analog and digital-to-digital distribution of the MPX signal.
Optional µMPX compression is available to reduce the cost of transportation by using inexpensive network links.
Features include Forward Error Correction and redundant dual streaming with time diversity in PCM to ensure reliable transportation of IP streams. The codec uses the same hardware platform as the Iqoya X/Link range, and features internal redundant power supply units.

Evanov Communications recently switched on hybrid HD Radio on an AM station in Ontario. It’s believed to be the first AM to use HD Radio in Canada.
The company operates 16 radio stations across the country, including in the major markets of Winnipeg, Toronto, Montreal and Ottawa. Twelve of those are on FM, four on AM.
CHLO is in Brampton, a suburb of Toronto. The station is a Class B station broadcasting on 530 kHz with 1000W daytime operations and 250W nighttime to a non-directional antenna. Much of its programming caters to the area’s large South Asian population.
Director of IT & Engineering Paul Bury answered Radio World’s questions about it.
Radio World: What is the purpose of turning on HD Radio, is this a test, or a permanent change?
Paul Bury: We’re hoping that turning on HD will help combat the growing problems of noise and subpar audio quality that has plagued the AM broadcast band for many years.
With growing competition from FM broadcasters and online streaming, the listeners have grown accustomed to higher-fidelity audio and are slowly turning away from AM. We’re hoping that higher-quality audio will translate to higher hours tuned.
Because HD Radio on AM is new to us, we are treating it as a test at this moment. However, we hope that this will become a permanent change and a way to revitalize the historic AM band.
RW: How many cars in your market do you believe have HD Radio-capable AM receivers?
Bury: We have not seen many local stats showing a number of HD Radio-capable receivers. However, according to Xperi, there are more than 4 million HD-equipped vehicles in Canada, and one in three new cars sold in Canada every day come equipped with an HD receivers.
Over 30 auto manufacturers now ship their cars to Canada with HD decks — granted, some no longer include the AM broadcast band, but the majority still do. It’s safe to say that for the most part, if a vehicle comes equipped with FM HD, it will also have AM HD.
Since most receivers switch to HD signal automatically, we noticed with our FM HD operations that most listeners didn’t realize they were listening to the HD signal or that HD was even included in their car radio.
RW: Are you using the hybrid AM mode, or all-digital?
Bury: We are using the hybrid mode as we did not want to turn off the signal to those listeners who may not have HD-capable receivers yet. If tests in hybrid mode turn out to be positive, we will look into testing the full digital mode in certain dayparts, but as of right now, we’re not anticipating a full shutdown of our analog transmission.
A car tuner displays CHLO.RW: Hybrid on AM in the United States did not succeed, with early adopters having a lot of issues with noise and interference, especially at night. Is there cause to believe it will work now?
Bury: The interference and noise issues are highly dependent on the broadcaster’s frequency.
We have specifically chosen CHLO to be our test station because of the frequency that it uses. Being at the very bottom end of the AM dial, 530 kHz is being utilized by very few stations in North America. This means that the interference levels are very low.
During our application process with ISED, Canada’s spectrum management body, we were asked to notify stations within 500 km of us on co-channel and first-adjacent frequencies. In Canada, we found that most of these stations have either gone dark, or switched to FM or other frequencies. Other broadcasters may not be so lucky.
Our own tests do confirm that the HD signal does not cope very well with any kind of interference past the 10 mV/m contour, including that which is generated by the new, fully electric transit busses the city has started rolling out.
RW: Is it correct to say that this is Canada’s first AM IBOC station?
Bury: Yes, CHLO is the first station using IBOC technology on the AM dial in Canada. Other broadcasters, us included, have chosen to simulcast their HD stations on HD subchannels of their FM sister stations or repeaters. Even though some have investigated setting up AM IBOC operations, for their own reasons, they never did.
RW: What is the digital air chain?
Bury: The air chain consists of a 900 MHz STL feeding into a Orban 9300 workhorse audio processor for the analog portion and an Omnia One for the HD portion. We started off running both on the Orban 9300 but found that the high frequencies were not very pleasant to listen to. The combined HD and analog signal then comes out of a Nautel NX3 transmitter running at 1000W during the day, 250W at night in analog into a single-stick 740-foot antenna.
RW: What are your observations about the signal quality and coverage so far?
Bury: So far, we noticed that the HD coverage is excellent out to about the 10 mV contour in the city limits, which perfectly covers our city of license and primary target area. In the countryside and away from human-made interference, the HD receivers have a pretty solid lock out to about 5 mV. Thus far we have not received any DX reports showing lock on skywave propagation and we’re waiting patiently for those to roll in.
RW: What comments have you had from listeners?
Bury: We’ve received nothing but positive comments from our listeners, mostly praising us for the added program data. Several have noticed the higher-quality audio, saying it’s comparable to online streaming and “less muffled.” Several of our advertisers have also noticed the improved audio quality and have shared their positive feedback.
RW: A DXer board posted a complaint that the signal is “wiping out 518 kHz Navtex.” Is that the case and what if anything should be done about that?
Bury: We have not received any reports of interference to other services nor broadcasters yet, so this is the first time I am hearing about it. We will investigate all reports of interference as is required during our testing phase by ISED.
Luckily, there are many things that can be done to mitigate such interference. We can play with the power of each IBOC sideband or even turn one off if required. We have a message playing on the air asking for reports of any interference via email to hd@am530.ca. The same address can also be used to send us reception reports.
RW: What else should we know about the project?
Bury: This has been a very exciting project for us, it was also a good learning curve to overcome. One of the challenging parts to the project was alignment of audio processing so that the switch from digital to analog in the weak reception areas is not too shocking to the ears. This is still a work in progress but we’re already seeing great results.

He’s been the leader of the company he founded with the purchase of an AM radio station in Secaucus, N.J., in the early 1980s — a property that served as the foundation of Spanish Broadcasting System (SBS) instead of the one he really wanted, the FM that today is Z100.
Now, Raúl Alarcón Jr. is handing his Presidential title to the individual that serves as SBS’s Chief Operations Officer.
Adding the role of President is Albert Rodriguez.
He’ll retain his COO title, as Alarcón focuses on his role of Chairman/CEO.
As President, Rodriguez will manage all aspects of SBS’s operations and oversee the future growth and financial performance of SBS’s radio, TV, digital and experiential businesses and brands.
In addition to its broadcast radio stations, SBS’s assets include the Aire radio network; Hispanic streaming app LaMusica; the MegaTV operation; and concert promoter SBS Entertainment.
Alarcón said, “Albert has demonstrated an amazing ability to deliver industry-leading financial results for the company during the most extraordinarily challenging times in the history of electronic media. He has personally spearheaded a number of corporate initiatives which have been instrumental in establishing the Company’s leadership standing, while adroitly handpicking an executive team which is second-to-none in the industry.
“After nearly a quarter century of dedication and loyalty in building a track record of
stellar achievements, no one is more qualified than Albert Rodríguez to expand upon
this Company’s treasured legacy of nearly four decades of service to the nation’s Latino
community. I congratulate him on his many accomplishments and very much look
forward to his firebrand leadership of SBS in the future.”
Rodriguez commented, “I am honored that Raúl is entrusting me with these added
responsibilities, particularly at this time of universal recognition and acceptance of the awesome power of the Latino consumer. I look forward to continue executing our
Chairman’s vision, which has created extraordinary value for the Company and its
shareholders, and to working with our amazing team of content and sales professionals
as we together write the next exciting chapter in the history of SBS as the preeminent
entertainment destination for U.S. Latinos.”
SBS also notes that it will be implementing “additional management initiatives” in
the coming weeks “as part of its ongoing efforts at solidifying and expanding its
competitive standing in the U.S. media marketplace.”
The company did not elaborate on what that may entail.
Dan Slentz bought and installed a Rhode & Schwarz “Spycer” network storage system for his UHD video. It’s 2 petabytes, or 2,000 terabytes, and uses about 15 rack units in RAID5 configuration, all linked by fiber through a network fiber switch to Dan’s five edit cells and four record servers, which use 6 TB SSDs to record up to three hours of UHD video. The write speed of the SSD (Solid State Drive) is necessary for UHD video because spinning disc drives wouldn’t work.
While learning more from the Rohde & Schwarz website, Dan found a neat poster that Workbench readers will want. It gives a visual overview of the radio frequency bands and regulations “in today’s and tomorrow’s cars,” including broadcast, mobile communications (3G to 5G), communications (Wi-Fi, V2X etc.), global navigation, radar sensors and EV charging.
As the company notes, “Being able to manage the coexistence and interference of the various radio frequencies in an (electric) car is a major challenge for research, development and testing of in-car.”
The poster is available via mail or download.

Helping hand As seen on the Radio Shack site, the Hot Holder’s molded silicon block aids in construction projects.Longtime Workbench readers may recall the “home-brew” console that a young enterprising Dino Gatsoula built, complete with remote starts and status indicators, which we featured in 2018.
Dino’s 24/7 Greek-formatted station, which he runs with his dad, is now an internet station, having graduated from SCA status.
An avid hands-on engineer, Dino found a useful soldering device, shown in the first photo, at the Radio Shack online store.
The Hot Holder is a stamped silicon block with holes to mount a variety of connectors and parts, as identified in the second image. It serves as a third hand when you are either soldering or assembling.
To that end, there are even a couple of slots for holding wires that need to be tinned or soldered together.
Head to radioshack.com for more information. And if you like Modern Greek music, listen to Dino’s internet station by visiting www.radioedra.com.
Available from Radio Shack online, the block can be used for a variety of connectors, and even wires. A peek inside (or behind)Hall Communications Director of Engineering Edd Monskie is a deer hunter and sports shooter. Edd was looking for an inexpensive borescope to see down rifle barrels to check their condition and to inspect up close for flaws not easily seen by the naked eye.
Edd checked Amazon and found a variety of new LED-lighted borescopes. Most are under $100, and one is about $20. They usually have a USB connection, and many have a plug for direct access to Android phones. Since Edd uses an iPhone, he had to purchase a small Wi-Fi adapter as well.
Some are listed as “endoscopes,” although for our engineering application, these devices can be used for hard-to-reach equipment inspections. The LED/camera is mounted on a 3-foot or longer flexible cable, giving you a really good video picture of whatever you need to see over, under or inside. The model Edd bought has adjustable LED lighting, which is really helpful in dark locations.
Some people even use them to see inside engine cylinders with the spark plug removed. Aside from using it for his firearm inspections, Edd has used it to see various places inside racks and transmitters, even down a clogged sink drain.
A quick search of Google or Amazon will bring up a variety of choices. Just enter “borescope” or “endoscope” in the search block.
For inspections, Edd likes that you send the cable — rather than your face, hand or phone — into the dark location.
