WorldCast Systems, the supplier of advanced broadcast products, is pleased to announce “the further evolution” of its APTmpX product, a “non-destructive” MPX/composite compression algorithm.

Despite the advent of the internet and digital broadcasting standards, FM remains the world’s most popular transmission format and a central technology in radio broadcasters’ efforts to maximize their reach and audience. As a result, new technologies have had to be created to enable an FM-centric workflow to also work for internet delivery.

The initial version of APTmpX, launched in October 2020, offered FM broadcasters access to high quality signal compression for the resulting centralized FM MPX/Composite transmission, solving the difficulty of maintaining both a high quality and a cost-effective transmission.

This provided a solution in the <900kbps region. The latest release of APTmpX takes this even further. Following optimization by Worldcast engineers, three new versions are available that offer new levels of compression at 600, 400 or 300kbps network bandwidth. This means the composite signal can now directly be transported with non-destructive compression from 600kbps down to 300kbps.

The use of APTmpX confers several advantages. Since the majority of composite equipment at transmitter sites is eliminated with a centrally generated MPX/composite signal, besides the obvious network savings, several broadcasters have already managed to save hardware costs with APTmpX. Furthermore, the company says, APTmpX combines signal fidelity with the best latency performance and makes it easier than ever to guarantee a consistent sonic signature across the transmitter network.

“Thanks to its low complexity and easy integration, APTmpX has already proven itself as the ultimate solution to enable a 100% digital transmission chain, bridging the transition from digital studios to digital transmitters,” said Gregory Mercier, Director of Product Marketing at WorldCast Systems. “With these new versions, we bring its power to a whole new section of the market, allowing broadcasters in areas of poor bandwidth penetration to deliver stunning audio quality to their audiences no matter what they are listening on.”

It’s known worldwide as a cloud-based multi-tenant platform provider.

At the end of this month, it will demonstrate how, in its view, “easy it is” to implement feature-rich OTT content delivery using the MwareTV platform to mobile operators, telcos and ISPs.

MwareTV will be getting a spotlight at Mobile World Congress, which begins February 28 in Barcelona and concludes March 3.

Mware TV can be found in Hall 5, stand 5J66. “Showcasing the platforms versatility, each visitor will be able to leave with a fully branded proof of concept service,” the company says.

“As an established, cloud-based content platform, MwareTV is able to add services very quickly, anywhere in the world. Users are presented with powerful functionality from content acquisition through delivery to white label Android and Apple apps, all simply customised and branded. Highly tailored and fully branded services can typically be online within four weeks.”

New at MWC2022 will be the latest version of the mobile apps, designed to provide a more enriched user-experience. “MwareTV handles all aspects of delivery, meaning ISPs and telcos do not need to delve into the technology of streaming: simply set quality of service expectations. In many markets, MwareTV can also supply licensed content for multiple channels and services, speeding still further the time to revenue.”

The cloud hosted MwareTV service is based on a “pay as you grow” concept, which means there are no high up-front costs. “As part of the proof of concept, MwareTV will supply a full costing calculator that provides a comprehensive forecast of the launch and running costs of any new service, leading to full investment transparency and profitability predictions. For telcos and ISPs, the ease of operation, ready to launch apps and financial transparency removes the significant barriers to entry and makes new services instantly competitive.”

Microphone manufacturer Heil Sound has new top leadership for the first time in its 56-year history.

The Illinois-based company said Bob and Sarah Heil have transferred ownership to current President/CEO Ash Levitt and Director of Operations Steve Warford.

“Sarah Heil has retired, but Bob will continue to do outreach work and product design within the amateur radio space under the title Founder and CEO Emeritus,” it stated.

The company said Levitt and Warford each began working with Heil Sound as teenagers, building and packaging products. “Levitt took a different career path in academia for a number of years, but continued to regularly consult with Heil Sound during that time. He returned to the company full-time in 2017 and assumed the role of president in 2020. Warford worked his way up in the company during his tenure and has been responsible for daily operations for the past several years.”

Bob Heil began his audio career as a teenager performing concerts as the house player on the Wurlitzer theater organ at the Fox Theater in St. Louis. According to a company bio he was also deeply involved in ham radio and began tinkering with electronics and electronic design.

He opened “Ye Olde Music Shoppe” in Marissa, Ill., in the early 1960s and found success catering to professional touring bands. Heil Sound was formed in 1966 to provide pro touring gear and systems, and system design and equipment for music festivals.

Among his innovations is the famous Talk Box used by Joe Walsh and Peter Frampton, the quadrophonic mixer for the Who, and modular mixing consoles. The company entered mic manufacturing in the 1990s based in part on the prompting of Bob Heil’s friend the musician Joe Walsh.

In its announcement of the transition, the company quoted Bob Heil saying, “My life has been about achieving great sound, whether on the concert stage or in the amateur radio world. … This company has been my passion but it is time for me to step aside.”

An image from Dielectric shows a scale model of an antenna and an HFSS virtual version

The National Association of Broadcasters supports the idea of allowing computer simulations for FM antenna directional patterns — as long as certain guardrails are in place.

“NAB believes that computational simulation of FM directional antennas is already mature and can produce comparable accuracy to physical measurements, thus minimizing the potential for new interference,” it wrote in comments filed with the Federal Communications Commission.

But it cautioned that “electromagnetic modeling software is complex, can be subject to manipulation, and limited by the accuracy and completeness of the input data.”

In November the commission opened an NPRM on this issue and proposed to permit the modeling. The change was urged in a joint petition from Dielectric, Jampro, Radio Frequency Systems and Shively Labs, all of which make antennas, as well as broadcaster Educational Media Foundation.

The most common reason to use a directional antenna by a commercial full-power FM station is to allow it to “short-space” to another FM station while maintaining contour protection to that station.

NAB wrote in its filed comments that the accuracy of computer simulation is “fundamentally dependent on the accuracy of the data input to the software.” So the association urged the FCC to require that full documentation of the underlying data and its sources be available to the commission and to “interested parties upon request.”

It wants the FCC to require the following: a statement of the qualifications of the people responsible for modeling; a complete description of the antenna system; limits of 15 dB max/min in the azimuth plane and of 2 dB/10-degree rate-of-change in the azimuth plane; and certification by a licensed land surveyor or equivalent that the antenna is oriented properly and installed at the correct height.

On other aspects, the NAB said the FCC should not require “in situ” measurements beyond ensuring the proper installation of the antenna. The commission should accept results from any appropriate electromagnetic modeling software. And, NAB said, absolute accuracy is not practically achievable, so the commission shouldn’t try to attain prediction accuracies that don’t materially affect the interference environment.

The FCC Media Bureau has finalized a filing penalty against the winning bidder of an FM construction permit for Hugo, Colo., reducing the fine to $1,000 and calling the error a “minor delinquency.”

ScarboroughRadio LLC, a winning bidder in Auction 109, failed to file a post-auction Form 2100, Schedule 301 long-form application until a couple of weeks after the deadline last September.

Applications can be dismissed outright in such circumstances, the commission pointed out; but an applicant can establish good cause if “minor, inadvertent” post-auction delinquencies don’t disrupt its auction process or undermine its goal of facilitating rapid implementation of service.

[See Our Business and Law Page]

In issuing a notice of apparent liability in December, the FCC waived the deadline, saying that Scarborough had complied with its other obligations, there was no indication of bad faith and the late filing was a minor violation. That meant Scarborough could go ahead with its plan to add FM service to Hugo.

But the FCC did propose a $3,000 fine in the NAL. Company principal Scott Scarborough then filed a response, noting that he is a first-time auction participant, and that after working with the Media Bureau staff on preparation of the long-form application, “it was his understanding that there was no more to be done, that the filing was complete and that there were no issues regarding late filing.”

The commission now has issued a forfeiture order. It said auction bidders were informed through various means of the rules for the post-auction long-form application; but, it continued, Scarborough replied to its NAL promptly, made its final payment and met the other relevant obligations.

“These facts, combined with the fact that Mr. Scarborough proactively reached out to bureau staff to complete the late-filed application, support Scarborough’s assertion that its late application filing was wholly inadvertent.” For this “minor post-auction delinquency,” the FCC settled on a reduced forfeiture of $1,000.
