In late March, further progress was made in incrementally easing some of the regulatory challenges faced by AM radio stations. This latest batch of new rules, which covers an array of mostly AM “moment method” proof-of-performance related issues, became effective with the publication of the adopted rule changes in the Federal Register.

The text and background for the changes can be found in the FCC’s Third Report and Order in MM Docket No. 13-249 (; I’ve summarized the changes for you at the end of this article.

Radio World readers know that these new rules are a continuation of the FCC’s AM revitalization efforts, which are intended to ensure their continued viability of the AM band. The First Report and Order in MB Docket No. 13-249 ( started it all by opening the companion FM translator process, modifying principal community coverage requirements, eliminating the “ratchet rule,” easing the MDCL implementation process, and relaxing the AM antenna efficiency standards. With more AM-friendly rule changes likely in the future, it’s worth taking a moment and reviewing impact of the first R&O and the drivers for AM station relocation and the potential benefits and challenges of collocation.

As has been discussed in Radio World, the AM radio business model increasingly has become challenged by competing services, a rising noise floor and shrinking effective coverage reach. Meanwhile, the rug is almost literally being pulled out from under existing AM stations as rising real estate values and more lucrative land uses pressure these stations to either find a new transmitting location or go dark.

Developing a brand-new site is fraught with time- and cost-intensive processes such as local permitting, legal contracts, environmental concerns and other hurdles. Often the involved costs and timeframes far exceed the costs of on-site engineering, equipment and construction. As a result, station collocation at an existing AM antenna site is becoming the most attractive option.

The collocation of an AM station with “non-AM” towers, such as FM or TV towers, is often possible, but requires a bit of forethought and may not always be a practical option. Typically, these towers are not base-insulated, so a properly designed skirt wires system must be installed on the host tower to accommodate the AM operation. Depending upon the tower height and the involved AM frequency, some skirt systems can become complicated, and involve tuned and detuned (isolating) sections. Also, insulators will have to be installed in the existing guy wires, (for guyed towers), and a suitable ground system still has to be plowed in.

The often “simpler” option to consider is the use of existing AM transmission sites since much of the necessary infrastructure is already at hand. Of course, the existing tower heights and ground system radial lengths must be compatible — for instance, diplexing a 630 kHz station into a 1590 kHz station may not be feasible because of the big difference in wavelengths. On the other hand, the involved frequencies must not be too close either, due to practical filtering considerations.

A non-directional station can, of course, look at collocating at another non-directional station’s site. Or in the alternative, a non-directional station can share a tower at an existing directional site. This requires the de-tuning of unused towers at the host site in addition to the customary diplexing system filtering hardware and matching system.

A directional station seeking a host will look for another directional station since the necessarily larger acreage is already available at an existing directional site. Of course, you still need to evaluate existing towers at that site to assess whether the heights are compatible and the geometry (tower layout) can accommodate the design needed for your station’s pattern from this new vantage point. Sometimes you can add another tower or towers to an existing site to make things work — and quite often (from a local zoning standpoint) it can be easier to add towers to an existing site than to try to develop a new site from scratch. One caution — even if the tower heights and geometry seem to work, careful consideration has to be given to the involved filter circuits; some situations do not lend themselves to practical (or achievable) solutions.

Site selection and the business case go hand in hand, and the cost implications of collocation are numerous and sometimes complex. What lease terms are available? What replacements, repairs or upgrades will be needed at the site for successful collocation? Are there environmental issues that could become a shared responsibility? An experienced broadcast communications lawyer should be sought to answer these and other related questions.

In all these scenarios, the site location and geometry of the host tower array must meet the tenant’s purposes while still satisfying FCC-mandated (day, night and sometimes “critical hours”) protection of other stations. The site must also be able to provide the desired coverage into communities of interest as well as the station’s city of license. Fortunately, aspects of the FCC’s signal protection requirements and, to a greater extent, principal community coverage requirements and antenna efficiency have been revised under the FCC’s First R&O, providing greater flexibility for site relocations. Other potentially more significant rule changes remain under consideration in the FCC’s “Further Notice".


Skipping back to this article’s beginning topic — the Third Report and Order’s rule changes — the FCC relaxed the partial proof rules for conventionally proofed antenna systems by reducing the number of measurement radials required. You need to only measure eight points on each radial that includes a monitor point.

For arrays proofed with Method-of-Moments technique, the FCC eliminated the biannual sample system recertification requirement. (Recertification is only needed when sample system equipment has been repaired or replaced.) They also clarified the base region model shunt capacitance assumptions that can be used in a MoM proof, eliminated the need for a surveyor’s certification when an existing AM array’s towers are involved for a new station or design (as long as no new towers are added or the existing geometry changed), and deleted the requirement to take new reference point measurements when the same array and pattern is being relicensed.

“Stay tuned” — more changes are likely and warrant our attention and comment as they are being considered.

Madeleine Noland is Chair of the ATSC 3.0 Technology Group.

To keep pace, broadcast TV migrated to digital signals over the past 20 years, representing the first major technology shift since analog color TV was introduced in the 1950s. Digital broadcast TV offers improved, high-definition pictures, more realistic sound, more channels, and more choices.

But changes in media, how it is accessed and consumed, and consumer behavior continued to evolve at an increasingly rapid rate.

Consumer expectations, new platforms

Consumers, quick to adopt new media and ways to tap into it, have come to expect the ability to access sight-and-sound content from any source on any device, anywhere, anytime – whether that content is broadcast over-the-air, delivered via cable, satellite, phone lines or stored at home.

Digital TV was a start in this direction, but the past dozen years have witnessed technology revolutions in nearly every related field and consumer expectations have risen accordingly. Alternative delivery paths have proliferated. Receiving devices such as smartphones and tablets have proliferated. Consumers expect interactivity. Behind the scenes, major improvements have taken place in video and audio coding efficiency, while broadcast spectrum has become scarcer.

The role of standards

Invisible to consumers are the technical standards that enable solutions to broadcast TV’s challenges. Standards really provide the basis for fundamental shifts in technology because they ensure the interoperability and economies of scale that lead to innovation and market adoption. The standards for digital TV were developed beginning in the late 1980s and approved by the FCC 1996, and it took nearly a decade to move the market to widespread adoption.

As consumers came to expect access to content historically delivered by broadcast TV pretty much anytime, anywhere and device-agnostic, those involved in conceiving and writing applicable standards had to lead the way to a sustainable future. And achieving that future, meeting consumer expectations, meant that new standards had to be extensible, scalable, and adaptable to unforeseen developments.

These are the challenges that have been met by ATSC 3.0, which now has regulatory approval from the U.S. Federal Communication Commission for voluntary commercial services, clearing the way for actual trials in test markets to understand best practices for applying the ATSC 3.0 standards for the next-generation of broadcast TV and how consumers respond to new service offerings.

The process

The process for achieving the ATSC 3.0 suite of standards that enable a future-oriented, commercially viable business model for broadcast TV and commensurate consumer benefits is similar for most technical standards. I will not bore readers of The Broadcast Bridge with the minutiae of actual standards writing and approval. (I personally find it fascinating, but it’s not everyone’s top choice.) Suffice to say that it requires years of work by hundreds of dedicated individuals from the worlds of industry, academia, consultancy, public interest and policy, as well as sponsors, to develop the underlying concepts, architectures and features and hash out the standards to support them. The process basically requires a global consensus among all participants, who bring their collective expertise to bear on every detail of myriad technologies and how best to define them for commercial use in the real world.

This process more or less culminated in 2017 with approval of the bulk of ATSC 3.0 standards and led to the March 2018 approval of commercial licenses by the FCC in specific U.S. markets that will test current best practices for applying the standards and contribute to new ones.

Launching in the ‘real world’

As you read this article, two major trials are underway in “model markets” to test ATSC 3.0 services, consumer response to the offerings and also the simultaneous delivery of ATSC 1.0 which was mandated by the FCC for stations launching ATSC 3.0 services.

In January, Sinclair Broadcast Group and its partners announced that it would broadcast ATSC 3.0 signals in Dallas, Texas. This trial is viewed as a first step toward a national service launch in some or all of Sinclair’s 100 U.S. markets. The Pearl TV Business Alliance – a coalition of broadcast groups backing ATSC 3.0 – announced its Model Market project in Phoenix, Arizona, in concert with 10 local stations there. The two trials, and others such as the joint NAB-CTA ATSC 3.0 test station in Cleveland, Ohio, will exercise different business use cases that the system enables.

These ongoing trials are providing implementers and the ATSC 3.0 community with new insights on recommended practices for implementing the standard, a variety of business and use cases and consumer response to the enhanced services and content on offer. One of our key ATSC 3.0 initiatives going forward is to maintain dialogue between our group and early implementers to improve the standards when additional clarification is needed and help see that the future for broadcast TV is as bright as we envisioned.

Resulting benefits

The ATSC 3.0 standard enables broadcasters to explore many new business models and opportunities, including the long-coveted ability to establish a one-to-one relationship with individual consumers. The creation of hybrid over-the-air (OTA) and over-the-top (OTT) content based on ATSC 3.0 standards is really the first time that broadband and broadcast have been “married,” on a common IP backbone. If new consumer-facing value propositions create “stickiness,” and a competitive advantage, we are likely to see rapid adoption of ATSC 3.0.

With the marriage of broadcast and broadband, consumers will finally realize their evolving demand for access to content from any source on any device, anywhere, all with immersive audio, high-definition video, added services (including improvements in public emergency notifications) and interactivity. In fact, it is difficult to put into words the leap in sensory richness that ATSC 3.0 will enable.

To enjoy these advancements, consumers will need a “receiving device,” and various devices and form factors are expected to come to market. It could be a new ATSC 3.0-enabled TV, a box that feeds 3.0 to your current TV or a mobile device, or perhaps even an autonomous vehicle.

In 2018, after many years of dedicated work, participants in the standards development process for ATSC 3.0 will finally see the fruits of their labors in setting a 21st Century course for the evolution of broadcast TV that will revitalize the industry and bring consumers a plethora of delightful, sensory-rich benefits.

She Will Succeed Chernock in May

WASHINGTON, Feb. 20, 2018 – The Advanced Television Systems Committee’s Board of Directors has selected Madeleine Noland of LG Electronics to lead the ATSC’s primary technology group supporting implementation of the new ATSC 3.0 next-generation broadcast TV standard. She will succeed Triveni Digital’s Dr. Richard Chernock as Chairman of the ATSC Technology Group in May.

“Throughout the development of the ATSC 3.0 suite of standards, Madeleine has been a consistent and dependable leader. She is adept at forging agreements on difficult technical issues within the collaborative standards development process. Following in Rich’s footsteps is a logical progression for her. We are delighted that Madeleine has accepted this new assignment to guide the Technology Group’s continuing development of standards and recommended practices,” said ATSC President Mark Richer.

The 2016 recipient of the ATSC’s highest honor, the Bernard J. Lechner Outstanding Contributor Award, Noland has been a key player in the development phase of Next Gen TV powered by ATSC 3.0, Richer explained. For instance, as the Chair of the Specialists Group on Applications and Presentation for ATSC 3.0 (TG3/S34), Noland demonstrated “outstanding leadership and dedication,” he said.

The S34 group is focused on user experience, including support for next generation video and audio codecs, linear TV services, interactive applications, accessibility including closed captioning, and other features. She led the effort to develop key ATSC 3.0 features, including vetting of standards for watermarking, advanced emergency alerting, personalization and companion devices. The same group also enabled compelling high-quality video capabilities, as well as high dynamic range and wide color gamut solutions.

As Vice Chair of the S31 Specialists Group, Noland helped to frame the system requirements for ATSC 3.0, coordinating the full documentation of the new standard with the work of other committees. She also played an active role in developing usecase scenarios that describe the desired attributes of the new standard.

Noland began her career in television systems in 2004 with Backchannelmedia, Inc. (BCM), an interactive television technology developer. It was during her work with BCM that she first started working on ATSC projects.

Through her involvement in industry standards work, Noland’s efforts were noticed by longtime ATSC member LG Electronics, and she joined their ATSC 3.0 team, in LG’s Office of the Chief Technology Officer, in early 2013.

AM, FM, HD Radio, drones and the broadcast plant are were among topics of discussion at symposium October 13, 2017

ARLINGTON, Va. — This week’s IEEE Broadcast Technology Symposium featured a packed technical program, and Thursday’s sessions were no exception for the radio crowd.

The morning kicked off with sessions on AM and FM Broadcasting, chaired by Beasley Broadcast Group Chief Technology Officer. Mike Cooney.

First up was Stephen Lockwood of Hatfield & Dawson, who presented Ben Dawson’s paper on a “Three-Station Facility Exchange for Improved AM Service in Miami.” The consultants were tasked with getting the best coverage for WURN, WLVJ and WMYM, all owned by one broadcaster, while minimizing new tower construction and rule waivers. This was done over the course of three years and resulted in “one station that was tall, thin and blonde, and two others that weren’t too bad,” Lockwood said.

Next were Xperi’s Russ Mundschenk and Glynn Walden (retired from CBS Radio), who tag-teamed a presentation explaining “Allocation Evaluation for IBOC Power Increase.” Based on a test bed in the Northeast Corridor and other data, the two concluded about 60% of stations could increase power to -10 dBc, and a major limiting factor in IBOC coverage is the existing noise floor, among other findings.

Burk Technology Vice President/Chief Technology Officer Paul Shulins then shared an “Update to Bitrate Reduction Effects on Watermarking.” Shulins concluded that bitrate reduction does have an effect on PPM watermarking; voices seem to encode best at 23 kbps and the best results were found when the audio processor is placed before the PPM encoder in the air chain.

Shulins then moved on to his next role as chair for the sessions on Using Drones for Broadcast Engineering and Production, during which Cavell Mertz & Associates’ John Kean explained “Antenna Radiation Pattern Measurement with a Drone,” including some advantages and disadvantages of the methodology.  

This was followed up by a presentation sharing “Real World Results for a Signal Measurement Drone” from Ian Gair of Australian company SixArms (named for hexacopters and the “airborne radio measurement systems” acronym).

And Cox Media Group’s Dave Sirak ended the morning with a session entitled “Close Encounters of the Drone Kind” (appropriately named for a presentation held the day before Friday the 13th!).

The annual BTS Awards Lunch featured a keynote presentation from Sally French, founder of The Drone Girl website, as well as a brief address from sponsor company DAC System SA, a Swiss transmission system monitoring services company.

At 2 p.m., the Broadcast Plant Technology sessions kicked off, chaired by NAB Senior Director of Engineering and Technology Policy Kelly Williams.

Xperi Vice President of Connected Radio Bob Dillon shared thoughts on the timely subject of “Metadata Generation and Distribution” and encouraged attendees to think globally, rather than geographically because metadata delivery systems have already begun to make this shift.

Wayne Pecena of Texas A&M University then spoke about “Cybersecurity and the Broadcast Technical Plant,” giving insight into station vulnerabilities and what broadcast engineers can do to increase security.

Tech conference examines TV repack, hybrid radio and more October 10, 2017, By James O'Neal

ARLINGTON, VA.—The 2017 IEEE Broadcast Symposium returned to its Washington, D.C. area “roots” today after four years on the road. The technical conference, which has been an annual industry event since the early 1950s, kicked off with opening remarks from Society president William Hayes, who then introduced Symposium co-chair, Robert Weller.

“Welcome to the 67th IEEE annual broadcast symposium,” said Weller. “We have over 170 people registered this year, which testifies to the importance that working engineers and consultants place on this event,” noting that sessions would feature a number of industry leaders and cover a variety of technologies, including the U.S. TV broadcast spectrum repack, hybrid radio and more.

Before beginning the scheduled presentations, Weller shifted to a somber note, asking conference attendees to observe a minute of silence in memory of the three TV tower workers–Brachton Barber, Marcus Goffena and Benito Rodriguez–who lost their lives in the recent Miami job site accident.

Symposium attendees pack the presentation room at the Key Bridge Marriott hotel in Arlington, Va., the venue for this year’s event.

More than 30 broadcast-related papers are scheduled for delivery during the Oct. 10-12 conference, with topics ranging from cybersecurity to the development of cameras for 8K UHD operation, and presenters traveling from as far away as Japan and Korea. In addition to conference track presentations, the Symposium will also feature luncheon keynote addresses with speakers from the Department of Defense, the Library of Congress and the Drone Girl organization.   

Frederick D. Moorefield, Jr., Director, Spectrum Policy & International Engagements Office of the Department of Defense Chief Information Officer will be a Keynote Speaker on Wednesday, October 11, 2017 at the IEEE Broadcast Symposium. 

Mr. Moorefield is currently serving as the Director of Spectrum Policy & International Engagements for the Department of Defense (DoD) Chief Information Officer (CIO).  His primary duties include strategic oversight of DoD spectrum policy and plans as well as overall management of key DoD CIO international partnerships and outreach.  Mr. Moorefield represents DoD in a variety of national and international spectrum forums and provides spectrum resource management program oversight.  On a broader front, he leads overall DoD CIO international engagements and related activities to include technology transfer, foreign disclosure, and internet governance.  He has served in this position since October 2012.  
Mr. Moorefield joined Federal service in 1989 in the Air Force as a civil servant, where he served for 19 years doing Research and Develop and Acquisition.  He also served in the Defense Information Systems Agency at the Joint Spectrum Center for four years where he was first introduced to spectrum management.   

His education includes a Bachelor degree in mathematics from Wilberforce University, located in Wilberforce Ohio and a Bachelor and Master of Electrical Engineering degree from the University of Dayton in Dayton Ohio.
