The author of this commentary is engineer/project manager for American Amplifier Technologies. This is excerpted from the free ebook “Trends in Remote Control & Facility Management.”

Today I was thinking about the remote control at my first radio job. 

We used a 950 MHz STL to send audio and control information to the transmitter site and a 450 MHz TSL to return meter readings. We were reasonably happy to have forward and reflected power readings, the all-important ability to turn the transmitter on and off, raise and lower power, and, of course, a fail-safe wired to turn off the transmitter if the STL were to die. 

Beyond that, however, we had to guess. 

If the station went off, a lack of response from the remote control probably meant the utility power was off and the generator hadn’t started. But it also could mean the STL transmitter had failed, so we had to stop and look at the STL transmitter before driving to the transmitter site. 

And because we knew so little, every time we were off air, we had to pack the truck with parts and tools to fix most anything that might be wrong.

Now we can look remotely at just about everything at the site, well beyond basic transmitter parameters … site temperature (inside and out), generator status, exact voltage from both utility and generator, not to mention live camera views of the transmitter, room and front door. 

Depending on what I learn remotely, instead of driving to the site, I might be able to simply shut off and restart power to one rack component to get back on the air. The beauty of current technology is that emergency trips to the transmitter site are rare. Which, honestly, is the core purpose for a remote control system.

The problem with the now antiquated system at my first station is that I could know only a tiny fraction of the available information about the equipment. Fortunately, it’s no longer necessary to view my equipment through a pinhole. 

In a time when staff and contractors are working harder and spreading their talents across multiple signals, having a basic remote control is now more expensive than upgrading. Making up for lack of information requires time, and unfortunately, it often means off-air time. 

By necessity, most engineers can’t get to the transmitter site as often as they would like, feeling lucky to schedule a quarterly site check and cleaning. Therefore, having more detailed access to information about these critical systems becomes even more important, and allows the engineer to make good decisions about when visiting the site has become a critical priority — reducing the chance that the call to visit the site is an off-air alarm.

Through SNMP, equipment at most stations now provides a wealth of knowledge beyond voltages or GPIO, but not all remote control systems can take full advantage of it. 

It’s important to look for systems that can fully leverage the information and control SNMP provides, such as AAT’s EmPower system. Far beyond being able to look at exciter readings, SNMP can provide information about specific devices within the transmitter, show audio input levels, and so on.

Remote control is only useful if the information and control are available where you are. For many years that meant walking (or running) to the remote control to find out what was going on. Now, products like EmPower put everything you need, literally, in your pocket. 

Anywhere you have connectivity, you can receive alarms, evaluate readings and adjust parameters. It’s no longer necessary to drop everything to deal with a transmitter site problem — often a few seconds in the app will show what’s going on and allow on-the-fly adjustments. 

Security is also an essential component of your remote-control system, as the last thing anyone needs is to give an unauthorized party control over the transmitter. 

Security may involve careful implementation of firewalls or other protection options. EmPower uses a secure cloud service, making it easy to control who has what access. Now it’s possible to ask the board op or consultant to check readings or reset components, as desired, while keeping the bad guys out.

Reflected power readings used to be the only way to monitor the health of the antenna system. 

For example, water entering the antenna system used to be invisible. It would silently creep in over weeks or months, and unless someone happened to notice a very tiny change in reflected power, no one had any idea. Then suddenly, the station is off the air with catastrophic damage to the inside of the coax, something that’s very hard to fix quickly. 

Though AAT is happy to provide coax on short notice, it would be better to know about the problem before it was a disaster — knowledge that reflected power isn’t likely to provide. 

To help solve this blind spot, AAT can add vector network analysis to EmPower with its VNA option. The Empower VNA module can evaluate the health of the system in real time — while you’re on the air — and allow you to set alarms that will trigger whenever the antenna system changes from baseline measurements.

Thankfully, guessing what’s happening at the transmitter site is no longer a necessity because remote control technology has indeed come a long way.

The post Remote Control Technology Has Come a Long Way appeared first on Radio World.

Radio World Buyer’s Guide articles are testimonials intended to help readers understand why their colleagues chose products to solve various technical situations. This month’s focus is on-air audio processing.

The author is a transmission specialist for Primedia Broadcasting. He is responsible for the transmission operations of 947/702 in Johannesburg and KFM/CapeTalk 567 in Cape Town, South Africa.

The word emoji owes its humble origins to the combination of two Japanese words for “picture” and “letter,” adding dimension to what otherwise would have been a “flat” or unemotive text message.

Primedia Broadcasting kicked off the year with a fun and modern out-of-home billboard campaign for CapeTalk 567, featuring today’s lingo.

While CapeTalk 567 prides itself on keeping things “real” with listeners through its programming content, there are technical systems that must work together to get the audio to its listeners as accurately and efficiently as possible.

CapeTalk 567 has been on the air for 28 years, primarily through its medium-wave footprint, serviced by a 25 kW transmitter on the outskirts of Cape Town operated by signal distribution service provider Sentech. It also streams its audio via the Primedia Plus app and as well as the DSTV Audio Bouquet (Channel 885).

For every commercial station on the radio “dial” (be they AM, FM or digital OTT platforms), there’s an ongoing conversation about how audio can be suitably “enhanced.” This is part of creating the sonic signature that adds to the listener’s experience when tuning into a particular station.

Broadcast audio processing over the years has remained a contentious topic for radio’s creative and engineering teams. Suffice it to say, the audio processor brings together the efforts of two diverse endeavours.

From an engineering perspective, the processor takes the lead in ensuring the transmission parameters (i.e. peak modulation) are always fully respected.

The “artistic” component considers how the audio is to be manipulated to create a particular sonic signature, through increasing perceived loudness along with achieving overall consistency of the program material.

There have been changes over the last 20 years or so that have affected audio quality on traditional transmission platforms.

In the world of medium-wave AM, it is both important and appropriate to maximize the density of the received audio, to ensure the audio remains intelligible.

External noise from devices such as LED lighting, laptops, computer power supplies and electric fences may impinge on a listener’s receiver, causing degradation in overall intelligibility. Studies have shown that this increase of external noise has been as much as 20 dB.

The only mitigation would be to increase audio density.

Years ago CapeTalk 567 had elected, via service provider Sentech, to use an Orban 9200 Optimod AM, which was installed at the transmitter site. This was at the time a departure from the traditional “analog” style of processing, as it made use of digital signal processing techniques.

Through investigation and listening tests, we found that the internal processing architecture of the 9200 presented some limitations for allowing a significant increase in audio density without degrading overall audio intelligibility.

It was clear that enhancing the audio quality of CapeTalk 567 now would require replacing the processor. I considered the options and elected Orban’s XPN-AM, purchased through Orban’s SA representative Prosound. They have been responsible for Orban’s South African sales and support since 1980.

The XPN-AM would be installed at Primedia’s Greenpoint studio facility. The 9200 would be retained as a backup at the transmitter site.

Having two independent audio processing paths within the XPN — one feeding the present AM signal and the other feeding both audio stream/DSTV platforms — provided us the maximum benefit for our signals, and the added benefit of being able to adjust the unit remotely rather than while standing in front of it.

The XPN’s processing enhancements have benefited CapeTalk 567’s on-air signals. Station Manager Tessa van Staden and Technical Operations Coordinator Brett Kannemeyer both have noted improvements in audio intelligibility, clarity and consistency across its broadcast platforms.

A further significant benefit is in the processor’s application to AM systems that permit the use of Modulation-Dependent Carrier Level technology, the dynamic reduction in carrier levels with the change in modulation levels.

MDCL can produce significant savings in transmitter energy consumption, an important consideration for AM radio stations. MDCL implementation is a priority for the Sentech-owned Nautel NX25 transmitter later this year.

Cumulus Media has released its 2025 financial results, and the data offers a better sense of the urgency surrounding its bankruptcy reorganization announcement in March.

Cumulus reported net revenue for the year of $742 million, a decrease of 10.3% from $827 million from 2024.

The media company’s net loss last year totaled $201 million.

As we have previously reported, Cumulus seeks to eliminate roughly $592 million in debt in a prepackaged reorganization with lenders in bankruptcy court. As part of the reorganization, Cumulus will become a private company.

A hearing to consider compliance with the bankruptcy code’s disclosure requirements, any objections and confirmation of the broadcaster’s plan will be held before U.S. Bankruptcy Judge Alfredo Perez in Houston on April 15.

Observers told us that the judge’s approval could come as early as May.

“The company’s recently announced financial restructuring marks an important step toward meaningfully reducing the debt burden that has constrained the business,” Mary Berner, Cumulus’ president and CEO, said in a statement.

For the fourth quarter of 2025, Cumulus reported net revenue of $188 million, a decrease of 14% from the same three months the year prior, and a net loss of $135 million in in Q4 2025.

Revenue breakdown

Broadcast revenue dominated Cumulus’ totals for the year. It reported $339 million of spot revenue, down 13% from 2024, and $136 million from its Westwood One audio network operations for 2025.

Digital, which includes the Cumulus Podcast Network, totaled $151 million, which was down 2% YoY. Another $116 million in annual revenue was attributed to “other” revenue.   

The Atlanta-based broadcaster finished the year with roughly $670 million of debt. Cumulus said in its bankruptcy filing that its debt had become unsustainable due to unrelenting challenges such as increasing competition from digital audio and streaming platforms, changes in the advertising market and recurring annual declines in its radio audiences.

“Looking ahead, we remain focused on building on the core strengths of the company to maximize value,” Berner said.

Cumulus, which has 393 owned-and-operated radio stations across 84 markets, did manage to shrink expenses in 2025. It said operating expenses last year were $880 million, which were down from just over a billion dollars in 2024. It reported having a total of 2,862 employees, 2,078 of whom were employed full-time.

The company’s most recent balance sheet reported capital expenditures of $20.2 million in 2025.

According to court documents, Cumulus recently reached agreements to retain its top leadership throughout the bankruptcy process and through the end of 2026. That includes the 66-year old Berner, and CFO Francisco Lopez-Balboa, age 65.

The media company remains embroiled in a lawsuit with Nielsen regarding the ratings company’s bundled ratings policy, though the case was paused by a federal judge after Cumulus filed for reorganization in March. U.S. District Judge Jeannette Vargas also issued a stay in the countersuit by Nielsen.

The latest round in a back-and-forth surrounding interference complaints from a full-power station near the North Carolina/Virginia border has resulted in a Federal Communications Commission order for the translator in question to shut down for now.

We’ve covered the interference complaints that stem back to the fall of 2024 from Lakes Media, the owner of Class C3 98.3 WLUS(FM) in Clarksburg, Va. Its antenna is located just across the North Carolina state line in Granville County.

After Lakes Media’s first interference complaint, the FCC ordered same-channel W252EL(FM), a 150-watt “Rock FM” translator licensed to Cary, N.C., to go silent until it could implement a directional antenna pattern that avoided overlap with the WLUS 45 dBu contour.

The owner of the translator, Curtis Media, said it did so, and it returned to the air last September under program test authority. Curtis filed an application for a license to cover the new facility.

(Read the commission’s decision.)

Lakes Media President Tom Birch quickly filed an opposition, arguing the application should be denied because WLUS was again suffering harmful interference.

The parties went back and forth some more. Curtis Media alleged that Birch repeatedly suggested paying $500,000 to settle the matter, “indicating that profit motives, not the interests of its listeners,” underpin Lakes’ interference allegations, according to the commission’s account.

Then in November, Birch and Lakes filed 10 listener complaints within WLUS’ protected 45 dBu contour, each plotted on a map, as well as signal strength data from each listener location.

“After enduring this three times since 2016, I am outraged that there are no FCC provisions for interference violators to be liable for reimbursing all of the expense incurred by the injured parties,” Birch told Radio World.

Birch ventured that Lakes Media spent “tens of thousands” of dollars in legal and technical expenses in trying to prove the interference.

Curtis argued that the latest exhibit was invalid because, among other reasons, nine of the listener complaints were clustered around the immediate neighborhood of Birch’s Raleigh-area residence.

“While the commission’s FM translator interference complaint process requires complaints to be from ‘separate receivers at separate locations,’ the commission surely did not envision ‘separate locations’ to mean more than a half-dozen houses in the same compact subdivision,” Curtis wrote.

The translator owner also argued those complaints should have been originally included in Birch’s 2024 filing. It further argued that its new antenna pattern, in terms of interference, was not being properly considered without the use of higher resolution terrain samples.

But the commission rejected Curtis’ argument about terrain accuracy and said that there is no rule or precedent supporting its claim “that listener complainants may not be clustered in a single neighborhood.”

All told, the Media Bureau found the latest evidence from WLUS compelling. While it cautioned Lakes and Birch against any possible abuse of process arising from financial settlement, it said that WLUS could not have collected the second round of listener complaints regarding the new pattern until it was actually on the air.

It found the complaints valid and, as a result, the Cary translator must shut down immediately. Curtis must first demonstrate, prior to any operation or processing of its new application, that it has resolved all listener complaints submitted by Lakes Media.

Radio World has also invited comment from Curtis Media.

With CBS News Radio about to sunset, a new operator will unveil a news network promising several technological advancements.

Live Channel USA is announcing the launch of the Radio Network News Service for U.S. stations. A bridge service will be available for affiliates beginning May 23 — one day after CBS News Radio is scheduled to shut down.

While the network has roots in European broadcast technology and maintains a global hub in London, the rollout — which Live Channel calls the “Change Bulletin Supplier” initiative — is designed for the U.S. market, according to founder Dan Warren.

The network follows a traditional barter model, providing top-of-the-hour and half-hourly bulletins available in one-, three- or five-minute segments with a standard national commercial load.

Its primary differentiator, Warren says, is localization. RNN utilizes a cloud-based system to produce customized offerings designed to feel more like a regional partner.

“For example, a significant Florida story that might not make a national cut will still appear on our Florida affiliates’ bulletins but not in New York,” Warren said.

The full network will roll out on June 1. It is led by a veteran team with international broadcast experience from outlets such as Sky News, the BBC and CNN.

Stations interested in securing market exclusivity for the May 23 transition can view the schedule and technical specifications at the RNN website.

Live Channel USA is based in Daytona Beach, Fla. and works to bring content to FAST channels on connected television services.

Three property owners in New York City have received “pirate radio letters” from the Federal Communications Commission.

The Notices of Illegal Pirate Radio Broadcasting inform the owners that unlicensed FM signals were detected coming from their respective properties and that they could be liable for significant financial penalties.

An LLC received a notice about an FM signal on 89.3 MHz coming from its property on West 189th Street of Manhattan last September.

David Duchatellier of the Jamaica neighborhood of Queens received a notice about a signal on 90.1 MHz last November.

And Thomas J. Chavannes and Beverley Dixon-Chavannes, also of Jamaica, got a letter about a signal this past January on 91.9.

New York is one of the markets in which the commission does regular pirate enforcement sweeps. The FCC said it looked into these cases after receiving complaints.

Each owner was given 10 days to respond “by providing evidence that you are no longer permitting pirate radio broadcasting to occur” and requesting them to identify the people engaged in the alleged pirate radio broadcasting on the property.

The post Three NYC Property Owners Get FCC “Pirate Letter” appeared first on Radio World.

He managed to work nearly 65 years in the biggest city in the U.S., and in doing so, earned the admiration of his broadcast engineering peers.

Richard Ross, a longtime chief engineer in New York City, died on Feb. 12 at the age of 89. He is survived by his daughter Erica, who shared many details with us from his life.

Ross joined 1280 WADO(AM) in the summer of 1972 as a relief engineer. By his count, he would withstand eight ownership changes until his retirement as chief engineer from Univision Radio in June 2020 at the age of 84.

Fellow engineers would call Ross frequently after his retirement, and for a time, he offered consulting services.

“He had a kind of Harry Potter-like knowledge of it all,” Erica said.

“Those who knew Richard lost a member of their family with his passing,” said Santos Lebron, engineering supervisor at Univision Radio New York.

Lebron’s relationship with Ross went back decades; they met when Lebron was hired as a relief engineer at WADO in 1977. He and others remembered Ross for being well-dressed and possessing a level-headedness, amicable toward all and harboring a bit of a mischievous side.

Ross knew of his fortune to work in the Big Apple for so many decades. “It is a rare occasion where one starts their career in any major city and they eventually work their way up the line to more important positions in major communications hubs,” he wrote in a piece for Storyworth.

Along with WADO, Ross spent many hours with the equipment above the Empire State Building when Heftel Broadcasting purchased 105.9 WNWK(FM). Univision’s radio footprint in New York would continue to grow with the addition of 92.7 WQBU(FM) in Garden City, followed by the trade of 105.9 with New York Public Radio for 96.3, then WQXR(FM), in 2009.

Early life

Ross was born to Helen and Edward Ross in May 1936 as an only child on Manhattan’s Upper West Side.

Erica recounted how he developed a knack for machines and tinkering early on. By age 10, Ross was already experimenting with his apartment building’s elevator controls — even figuring out how to send the doorman to the wrong floors.

For several years, he attended a boarding school in western North Carolina near the Blue Ridge Mountains. The experience of navigating his way back to Manhattan via train sparked a lifelong fascination with locomotives.

He later attended Brooklyn Technical High School, where he joined the radio club and, according to Erica, officially “caught the bug.”

Ross studied at the University of Bridgeport, earning his associate’s degree in electrical engineering. He went on to serve three years in the communications division of the New York Air National Guard and completed basic training at Keesler Air Force Base in Biloxi, Miss.

In 1958, he got his break into the radio business, joining Municipal Broadcasting System’s WNYC(AM/FM) as a provisional engineer.

Ross aimed to become permanent pending a civil service exam. Passing the exam, however, didn’t guarantee a full-time position due to fierce competition from others. But WNYC’s chief engineer at the time, Hom Hong Wei, offered some reassuring advice, and Ross got the position.

He would credit Wei as being one of his most influential mentors. At WNYC, Ross found himself exploring hidden corners of the city.

“I got to go places that nobody else goes such as walking to the top of Washington Square Arch and yes, there is a locked stairway in the south leg of the arch,” Ross would recount.

Many decades at WADO

By the early 1970s, Ross transitioned to WADO as a summer relief engineer.

For a time, he found the energy to work at both WADO and WNYC, before becoming permanently entrenched at the Spanish-language AM station, where he’d work well into the 21st century.

He wondered how he had the stamina to manage it all.

He’d go solely full-time at WADO, but Ross’ role went beyond its day-to-day. During the ’70s, the AM station would broadcast Black gospel music on Sundays, and it had brokered agreements with several churches in the south Bronx and Harlem.

Ross was tasked with recording the services, lugging RCA reel-to-reel machines to the locations. Others were known to turn down those assignments for one reason or another, but Ross happily obliged.

Even after WADO stopped airing the programming, he became entrenched with the churches, who would ultimately approach Ross to do separate recordings of the services. He would handle multiple recordings in a single day during the 1980s, and continued doing so through at least 2005.

They affectionately referred to him as “Brother Ross, our Gospel engineer,” viewing him as a part of their community. The services would be taped and sent to radio stations across the U.S. that aired Black gospel.

His spirit was evident in other ways. Ross became a member of the IBEW Local 1212, the labor union for broadcast engineers, in 1963.

He rose in its ranks, becoming part of the union’s executive board. Ross would stay even after he became WADO’s chief engineer in 1985, following the passing of his good friend Phil Greenstone.

With what would have been considered a management position, it was unusual for someone like Ross to remain in the union, both Erica and Lebron said. Ross wrote that he felt it was an honor.

“He was more than a colleague; he was a brother in every sense of the word,” IBEW 1212 wrote while remembering Ross on its website.

“All of us in this profession share the same situation,” Ross wrote in his Storyworth of his IBEW role. “We all know each other in New York City and once each month we meet to eat, drink and be merry and discuss our war stories.”

Ross was also a loyal member of the Society of Broadcast Engineers.

Meadowlands move

As the broadcast landscape evolved, Lebron remembered Ross best for coordinating WADO’s transmitting power increase in the New Jersey Meadowlands at the end of 1999.

As recounted by Scott Fybush, WADO had used a Blaw-Knox diamond-shaped tower from its transmitter site on Paterson Plank Road in Carlstadt. It ran 5 kW day and night as part of a power restriction on regional channels like 1280.

But the FCC lifted that restriction in the early 1990s. WADO sought to upgrade to 50 kW by day and 7.2 kW at night, which required a new antenna system.

The venerable Blaw-Knox tower came down, and three new towers were needed, along with a complete renovation of the 1930s-era building that housed its transmitters.

Then-owner Hispanic Broadcasting had filed for a construction permit, but most of the actual work did not commence until just prior to its expiration, which acted as a hard deadline.

As Ross wrote in his Storyworth, from October 1999 and for the next four months, he visited the Meadowlands site daily to complete the project under great stress and pressure.

Construction took place on sensitive riparian land. It required a year of hearings costing over $1 million, involving the state of New Jersey, the Army Corps of Engineers and the U.S. Coast Guard.

Laying down and completely removing temporary wooden plank roads alone cost $675,000, according to Ross. Union dock workers were hired to build a 1,000-foot boardwalk to the towers, and a crane had to be rented from the Tappan Zee Bridge.

With the main transmitter building modified and the heat shut off, crews worked late into the winter nights, running copper straps between the four towers with only a porta-potty out back.

He recounted the moment of truth:

“On February 1, I invited David Lykes, Hispanic Broadcasting’s chief operating officer, to come up from Dallas to push the activate button at 6  p.m.,” Ross wrote. “My heart was in my throat, but the damn system worked.”

The antenna system was designed by Ron Rackley of du Treil, Lundin & Rackley, who consulted on the project and praised Ross for its execution.

True to form

There were many other, less high-profile wins as well, often accompanied by 2 a.m. phone calls.

Ross was also well-known for his thorough tours of the Empire State Building’s broadcast facilities — Erica said multiple people have told her that those tours were highlights of their careers.

Also an amateur radio operator (K2RNR), Ross had many interests outside of radio, including locomotives and nature.

He loved the city, but ever since his boarding school days in western North Carolina, he became infatuated with the peace of a mountainside setting. Since the late 1960s, Ross owned a property in Kunkletown, Pa., in the southern portion of the Pocono Mountain region.

A lover of nature and an adamant conservationist, he viewed the country home as a sanctuary for wild animals. But he’d continue to call the Big Apple his main home and it was the only place he’d ever work.

In 2013, Univision honored his 50 years of broadcasting service by naming a studio after him.

True to his nature, he hated the attention and adamantly hoped people wouldn’t use the milestone to do the math on his age.

Ross passed away at home in his Hell’s Kitchen apartment — where he lived since 1964 — just shy of his 90th birthday.

Fittingly, the coroner described the lifelong engineer’s unforeseen cause of death as “an electrical short circuit of the heart.”

A memorial and celebration of life for Ross will be held Sunday, April 12, at the Masonic Lodge No. 72 in Secaucus, N.J.

FCC Chairman Brendan Carr chose a clear, blue-sky North Carolina spring day to travel to the top of a nearly 2,000-foot broadcast tower.

This was not the chair’s first rodeo — he also went to the top of the KELO(TV) tower in South Dakota last July and he has expressed his enjoyment of scaling such structures in the past. Carr used this latest opportunity, which included a live TV hit from the top of the eastern North Carolina broadcast site, to praise the efforts of America’s tower crews, including the one that aided him with his April ascent.

“It’s tower crews like this who maintain these structures; they are the reason why people receive these signals,” Carr told WCTI(TV). He said that there are roughly 20,000 tower climbers nationwide who support broadcast sites, along with towers for wireless communications and other services.

He shared a video on his X account:

Carr utilized a hydraulic hoist for the majority of the ascent before climbing the final 100 feet by hand, according to WCTI. The round trip took several hours.

The tower, located just west of New Bern, stands approximately 1,966 feet tall. In addition to serving WCTI, WYDO(TV) and WUNM(TV), it is home to 95.1 WRNS(FM), a Class C, 100,000-watt station licensed to Kinston.

According to Wikipedia, the structure ranks among the tallest towers in the United States.

The climb comes while crews are in the middle of a major maintenance project to replace the guy wires that stabilize the tower, according to WCTI. As a result of the work, WRNS said on its Facebook page that the station was off the air for several hours on April 6.

Nautel will be expanding its NX series of AM transmitters into the low-power market, with two models that support both analog and digital broadcasting.

The additions are the 1 kW NX1 and the 2.5 kW NX2.5. Scheduled to ship in the fall, the transmitters will be exhibited at Nautel’s NAB Show booth.

“Low-power AM transmitters haven’t had these kinds of capabilities in the past,” said John Whyte, Nautel’s head of marketing and product strategy, in a release.

The transmitters are built on the company’s NX series architecture, which Nautel said accounts for approximately 40 MW of high-power AM deployments worldwide.

Both models contain a 250 W RF power module developed to bring the same performance in low-power configurations. The module includes ultra-linear modulation and digital precorrection.

The NX1 and NX2.5 support HD Radio, including MA3 all-digital operation, as well as current DRM modes. They also include Nautel’s digital modulation architecture for linearity and spectral cleanliness.

The models include front‑accessible, hot‑pluggable RF power modules that contribute the same to the final output. Nautel’s HTML‑based user interface provides local and remote monitoring, while built‑in RF instrumentation offers system visibility.
