Exploring a 1 Million Watt Broadcast Tower (Radio World)

The father and son team of Joe and Jeff Geerling have teamed up on radio-related projects before.

Joe is a broadcast engineer, working into his fifth decade in the St. Louis market. He was market chief for CBS Radio for 20 years and today is the director of engineering for Covenant Network.

His son Jeff has spent nearly 15 years as a software architect and developer. He founded Midwestern Mac LLC and is active in many open-source software communities. Jeff recalls that one of his first web programming projects in the late 1990s was to construct an interface to display the current song on 98.1 KYKY(FM)’s initial website for his dad.

Last February, Joe appeared on a video on Jeff’s YouTube channel to install a Raspberry Pi IP KVM in a Covenant Network studio. That collaboration went so well that commenters on Jeff’s videos began clamoring for more appearances by the senior Geerling.

Over a family vacation, Joe and Jeff came to the realization that the iconic Crestwood Master Tower in Shrewsbury, Mo. — nicknamed by its original engineering community as “the Supertower” — would make for a perfect showcase for a new Geerling Engineering YouTube channel.

Given Joe’s expertise with the site, the idea for a video was a natural. In fact they ended up making two. [Continue reading…]

Amancio Ortega is testing the purchase of a former BBC headquarters in London for almost 90 million (West Observer)

The investment activity of Amancio Ortega in the United Kingdom does not stop. Pontegadea, the group that manages the equity investments of the founder of Inditex (Zara, Massimo Dutti, Bershka…) and the richest man in Spain, is negotiating the purchase of a new office building in London, as revealed on Wednesday by the specialized website CoStar News. This, citing market sources, indicates that the operation would be around 80 million pounds (89.7 million euros, at current exchange rates). The building, originally a printing press built in the twenties, is close to the BBC headquarters and, in fact, for years served as offices for the commercial division of British public broadcasting.

The property, renovated in 2015 by the construction company Kier and the firm Brimelow McSweeney Architects, currently houses a business of coworking (flexible office rental). Of the more than 3,000 meters built, 2,100 are available for rent, according to the building’s commercial brochure. Some websites advertise their tables for a price that exceeds 840 euros per table per month. It offers, in addition to parking for bicycles or changing rooms, a kitchen, private offices, meeting rooms or terraces on the upper floor (the fifth) and on the roof. To this we must add a privileged location in the center of the British capital, in the Fitzrovia neighborhood. The building is close to Soho, the British Museum and Regent’s Park.

What’s Going To Happen To Legacy Broadcast Bands When The Lights Go Out? (Hackaday)

Our smartphones have become our constant companions over the last decade, and it’s often said that they have been such a success because they’ve absorbed the features of so many of the other devices we used to carry. PDA? Check. Pager? Check. Flashlight? Check. Camera? Check. MP3 player? Of course, and the list goes on. But alongside all that portable tech there’s a wider effect on less portable technology, and it’s one that even has a social aspect to it as well. In simple terms, there’s a generational divide that the smartphone has brought into focus, between older people who consume media in ways born in the analogue age, and younger people for whom their media experience is customized and definitely non-linear.

Replacing Humans “Is the Furthest Thing From Our Mindset,” Says the Company Selling an A.I. Radio Host

RadioGPT can talk. It can research. It can take your calls. And it could be coming to your market.

The humble broadcast-radio host, whether a disc jockey or interviewer or reporter, has been going through it for decades now. The 1996 Telecommunications Act fueled the consolidation of local stations, decimating their staffs. The explosion of online radio, music and video streaming, and podcasting have upended ratings for shows on public airwaves. Phones and computers and smart speakers increasingly supplant radio sets. Funding for public radio is notoriously unreliable. It isn’t the best time for your modern-day Wolfman Jacks, or for any media profession.

On top of all that, your local DJ was already on the losing end of the artificial-intelligence revolution. Before the A.I. hype from last year, and even before the COVID recession demolished media ad markets, broadcast networks were gutting on-air talent at the both the national and collegiate level to trim budgets and automate programming: syndicating well-known shows and brands, prerecording and prearranging late-night broadcasts, training a roboticized voice to fill in the space when needed. Coupled with major streaming services’ dependence on algorithms and automation to curate playlists and make user recommendations—often with bizarre side effects—these developments make clear that the music industry anticipates the need for fewer humans down the line.

A.I. hasn’t yet finished killing the radio star, nor is it truly likely to anytime soon. But there’s a new digital buddy out there that might give hosts additional pause: RadioGPT, a new tool from the Ohio-based software company Futuri Media that fully digitizes the broadcast host as you know it.

New York’s Forgotten Radio Island (Messy Nessy Chic)

As far as islands go, Manhattan is one of the most famous and instantly recognisable. But if you were to charter a boat and sail around its coastline and through New York’s natural harbour you’d come across many more islands so small that hardly anyone knows are there. There are around thirty or so of these odd little islands, all mostly uninhabited or privately owned and strictly off limits, but filled with strange tales and peculiar histories.

Many of these islands are tantalisingly close to New York City, but remain out of reach. As travel writer Robert Sullivan put it “the islands are our silent neighbours. It is easy to live here and never notice them.”

[…]This story however, is about one such tiny island, just 150 feet square, and so small you can barely spot it on Google Maps unless you knew where to look. Once known as Little Pea Island, it is located about a mile off shore from Pelham Bay Park in the Bronx, and has room enough for just one building. It has been home to a Jazz Age era swanky yacht club, a radio station and for a while, the home to a glitzy Hollywood showbiz couple who ran a morning radio show from their home on the island. The last owner recently renovated the island into a self-sufficient, five thousand square feet luxury home, which today lies empty. [Continue reading the full story…]

Device transmits radio waves with almost no power – without violating the laws of physics (The Conversation)

A new ultra-low-power method of communication at first glance seems to violate the laws of physics. It is possible to wirelessly transmit information simply by opening and closing a switch that connects a resistor to an antenna. No need to send power to the antenna.

Our system, combined with techniques for harvesting energy from the environment, could lead to all manner of devices that transmit data, including tiny sensors and implanted medical devices, without needing batteries or other power sources. These include sensors for smart agriculture, electronics implanted in the body that never need battery changes, better contactless credit cards and maybe even new ways for satellites to communicate.

Apart from the energy needed to flip the switch, no other energy is needed to transmit the information. In our case, the switch is a transistor, an electrically controlled switch with no moving parts that consumes a minuscule amount of power.

In the simplest form of ordinary radio, a switch connects and disconnects a strong electrical signal source – perhaps an oscillator that produces a sine wave fluctuating 2 billion times per second – to the transmit antenna. When the signal source is connected, the antenna produces a radio wave, denoting a 1. When the switch is disconnected, there is no radio wave, indicating a 0. [Continue reading…]

Don Moore’s Photo Album: Cuenca, Ecuador (Part One)

Don Moore’s Photo Album: Cuenca, Ecuador (Part One)

by Don Moore

For me travel is all about seeing new places and having new experiences. When I retired in 2017 my plan was to spend the next fifteen years visiting new countries and new places in countries I already knew. Is that a viable goal? Three years ago while crossing the border from Ecuador to Colombia I shared a taxi with Dutch man who, like me, was traveling overland by bus with just a knapsack and a suitcase. And two weeks earlier he had celebrated his eightieth birthday. I don’t remember his name but he’s my hero.

The pandemic put a pause on travel but I’m happy to be back on the road. I’m currently in Ecuador, the country where I’ve spent more time than anywhere except the United States and Honduras. After landing in Quito at the beginning of December I visited four provinces I hadn’t been to before, including spending three nights at the bohemian beach town of Montañita where I had some good DX. I like seeing new places but there is also something to be said for returning to a familiar place that holds a special meaning. For me that place is where I am now – Cuenca, Ecuador.

My ex-wife and I finished our Peace Corps service in 1984, flew home to get married, and then in January 1985 flew to Quito, Ecuador to begin a long journey that would take us overland all the way to Buenos Aires and back. On our way to Peru in late February we stopped for a few days in Cuenca and fell in love with the little city. We visited Cuenca again in July at the end of our travels. When we left I knew we would be back but I never could have imagined the circumstances that would lead to that next visit. In 1997 we returned with our seven-year-old daughter to adopt a six-year-old son. We spent almost three weeks in Cuenca doing all the required paperwork but we had no complaints as we enjoyed being there so much. I clearly remember sitting in a park one day and commenting that Cuenca would be a perfect place to retire in someday. I was only ten years ahead of my time.

La Voz del Río Tarqui

Cuenca was home to several shortwave broadcasters over the decades but La Voz del Río Tarqui was probably the best known to my generation of DXers. The station was founded in 1960 by Manuel Pulla but didn’t begin its shortwave service on 3285 kHz until 1982. My loggings of the station run from July 1982 through 1997 but I believe they were on shortwave for a few more years after that. (Don’t confuse La Voz del Río Tarqui with Radio Tarqui, a sometimes broadcaster from Quito on 4970 kHz.)

La Voz del Río Tarqui in 1985. The facilities inside were no more impressive than the outside of the building was.

La Voz del Río Tarqui takes its name from the famous Battle of the River Tarqui. After the new countries of South America gained their independence from Spain there was often disagreement over just where the boundaries were that they had inherited from Spanish rule. Ecuador was in a union with present-day Colombia and Venezuela until 1830 and during this time Peru claimed much of present-day southern Ecuador, including Cuenca and Guayaquil. In 1828 a large Peruvian army occupied Loja, to the south, and a few months later marched north to complete their conquest. In February 1829 General Antonio de Sucre, a hero of the war of independence, met the Peruvians on the banks of the Tarqui, twenty-five kilometers south of Cuenca. Both sides suffered heavy losses but Sucre’s army routed the Peruvians. Cuenca, Guayaquil, and Loja remained a part of Ecuador. Continue reading →

Public radio engineers await fate of major antenna maker (Current)

The potential sale of one of the country’s only major manufacturers of high-power FM broadcast antennas is causing concern among public radio engineers who have long depended on the company for challenging projects such as directional antennas and multistation combiner systems.

Antennas and combiners made by Shively Labs carry the signals of many major stations, from Boston’s WBUR to Dallas’ KERA/KXT to Seattle’s KUOW. Shively’s headquarters in Maine boasts one of the few test ranges needed to fully prepare complex directional antenna systems for real-world performance.

Founded in 1963 by former RCA engineer Ed Shively, the company has been owned since 1980 by Howell Laboratories, an engineering firm that now has a wide range of product lines. Those include water purification systems, dehydrators and an increasing amount of contract work for the U.S. Navy.

While its military and commercial marine business has grown, broadcast antennas have become a smaller piece of the company’s portfolio, said Shively VP Angela Gillespie. [Continue reading…]

How to become a Shortwave listener (SWL) with Fedora Linux and Software Defined Radio (Fedora Magazine)

Catching signals from others is how we have started communicating as human beings. It all started, of course, with our vocal cords. Then we moved to smoke signals for long-distance communication. At some point, we discovered radio waves and are still using them for contact. This article will describe how you can tune in using Fedora Linux and an SDR dongle.

My journey

I got interested in radio communication as a hobby when I was a kid, while my local club, LZ2KRS, was still a thing. I was so excited to be able to listen and communicate with people worldwide. It opened a whole new world for me. I was living in a communist country back then and this was a way to escape just for a bit. It also taught me about ethics and technology.

Year after year my hobby grew and now, in the Internet era with all the cool devices you can use, it’s getting even more exciting. So I want to show you how to do it with Fedora Linux and a hardware dongle. [Continue reading…]

Radio history was made in Binghamton and one landmark still stands (Press Connects)

It was 1913, the year of the Binghamton Clothing Company Fire, and the year after the Triangle Shirtwaist Fire and the sinking of the Titanic.

Several major disasters that had left the region and the nation reeling from the loss of human life amidst a growing industrial base in the country. Thousands of immigrants were arriving to find new lives and work among the huddling masses. Many of those would make their way to the Binghamton area to find employment in the many cigar and shoe factories scattered on the landscape.

It was important to find a feel-good moment in the ever-rapidly increasing technology world that was changing the way we performed our work and lived our lives. Communication growth was one aspect of those changes. The number of newspapers and their influence was important, but so was the development of what we today call radio – originally known as wireless telegraphy, using radio waves to transmit telegraphic signals from point to point.

The first practical incarnation of wireless telegraphy was created by Guglielmo Marconi of Italy. The discovery of those waves had been made only about two decades prior to his use of those to transmit telegraph signals. In 1897, he formed the Wireless Telegraph & Signal Company in the United Kingdom. The company would later be called the Marconi Wireless Company, and continued to work on the ability to send these wireless signals farther and farther. Eventually, he also worked to see if these signals could be transmitted and received by moving objects, such as ships at sea and railroad trains. [Continue reading…]

Broadcast Signal Intrusions: When TV or Radio Stations Get Hacked (96.1 The Eagle)

Orson Welles’ contrived The War of the Worlds news bulletin “interrupted” a radio broadcast in 1938 to advise terrified listeners that aliens had invaded the Earth. As many as 12 million people were tuned in, according to NPR – and perhaps a million of them apparently worried that it was actually happening.

We’ve gained historical perspective on the stunt, even while the way we consume media has vastly changed over the decades that followed. Critics would later downplay the impact of The War of the Worlds, with some arguing that newspapers purposely over-sensationalized the broadcast to cast doubts on the trustworthiness of then-new technology that was siphoning off ad revenue.

What’s clear is that signal intrusions – including unauthorized hijacking of radio, television or satellite feeds – have continued ever since. They’ve served a variety of purposes, as you’ll see on the following list. Many were a form of political protest, while others were just looking to have a little fun. All of them trace back in some way to Welles’ fateful “interruption.”

Southern Television Broadcast
Nov. 26, 1977, England

Viewers of an early evening Southern Television broadcast in England were alarmed when an electronic voice purported to represent the “Ashtar Galactic Command” overtook the audio of a news segment for a full six minutes. The message, which was accompanied by a pulsating sound and eerie distortions, said: “For many years, you have seen us as lights in the sky. We speak to you now in peace and wisdom as we have done to your brothers and sisters all over this, your planet Earth.” This strange voice went on to advise humanity to “abandon its weapons” in order to participate in a “future awakening” and “achieve a higher state of evolution.” It also warned viewers that government officials weren’t who they claimed to be, and that they were leading the unwitting public into a New World Order. The hack ended with a final message: “Have no fear, seek only to know yourselves, and live in harmony with the ways of your planet Earth. We hear at the Ashtar Galactic Command thank you for your attention. We are now leaving the planes of your existence. May you be blessed by the supreme love and truth of the cosmos.” The interruption prompted a flood of phone calls from an understandably concerned audience then living under the threat of Cold War. A local newspaper said “thousands” of viewers were horrified; one man described the experience as “very eerie indeed” and said it “sounded very authentic.” A woman said she had to call her friends to make sure she wasn’t “hearing things,” adding that “it sounded like a genuine voice from outer space and was quite frightening.” An investigation revealed the Independent Broadcasting Authority’s Hannington transmitter had rebroadcast the signal from a nearby, unauthorized transmitter. The mastermind behind it all was never identified.

Blocking radio waves and electromagnetic interference with the flip of a switch (Phys.org)

Researchers in Drexel University’s College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The breakthrough, enabled by versatile two-dimensional materials called MXenes, could adjust the performance of electronic devices, strengthen wireless connections and secure mobile communications against intrusion.

The team, led by Yury Gogotsi, Ph.D., Distinguished University and Bach professor in Drexel’s College of Engineering, previously demonstrated that the two-dimensional layered MXene materials, discovered just over a decade ago, when combined with an electrolyte solution, can be turned into a potent active shield against electromagnetic waves.

This latest MXene discovery, reported in Nature Nanotechnology, shows how this shielding can be tuned when a small voltage—less than that produced by an alkaline battery—is applied.

“Dynamic control of electromagnetic wave jamming has been a significant technological challenge for protecting electronic devices working at gigahertz frequencies and a variety of other communications technologies,” Gogotsi said.

“As the number of wireless devices being used in industrial and private sectors has increased by orders of magnitude over the past decade, the urgency of this challenge has grown accordingly. This is why our discovery—which would dynamically mitigate the effect of electromagnetic interference on these devices—could have a broad impact.”
