It is 2010 and Colombian Colonel Jose Espejo has a problem. Not only is the Farc increasing its kidnapping activity, targeting police and military hostages, but many of the soldiers already in captivity – some kept in barbed-wire cages and held isolation in for over a decade – are losing hope of ever being rescued.
Colombia’s dense jungle and mountainous terrain mean rescue missions can take months to plan, especially because Farc guerrillas are known to shoot all hostages dead at the first hint of a raid. Colonel Espejo knew that in order for future missions to succeed, he would need to warn the captives that help was coming so they could be ready to make a break for it when the army arrived. But how do you get a message across to military hostages without tipping off their captors and placing them in even greater danger?
The unexpected solution – hide the message in a pop song with an interlude in Morse code that the military hostages could decipher. Soldiers learned Morse code in basic training, and it was unlikely that the Farc, who were not military trained, would know it. This is the tale of Better Days, a pop song with a secret Morse code message that became an actual lifesaver.
At the NAFB Convention, Simington said AM radio is an “indispensable resource”
FCC Commissioner Nathan Simington met with members of the National Association of Farm Broadcasting during their 79th annual convention on Nov. 16. In his remarks, Simington emphasized the importance of AM radio and outlined the steps needed to ensure its future in a changing market.
Simington began his remarks with a more personal anecdote. He said he grew up on a farm in Saskatchewan, Canada, where “besides the trade papers, there was no media institution more trusted to inform us about all we needed to know than AM radio.”
“AM radio was for us then, and is for the more than three million farmers across the U.S. now, an indispensable resource,” he said.
Simington said AM radio is the “essential spine” of the Emergency Alert System and “lets you know what’s happening not just globally, but locally — from school closures and traffic delays to city council and county management meetings and high school sports games.”
He comments on the growing populations that view AM radio as a “dead” and outdated technology, and why he believes that to be a falsity. [Continue reading…]
A collection of over 150 “QSL cards”, QSL? chronicles a moment in time before the Internet age, when global communication was thriving via amateur, or “ham”, radio operators.
Discovered by designer Roger Bova, the distinctly designed cards follow the international correspondence of one ham, station W2RP, who turned out to be the longest-standing licensed operator in The United States.
TAIPEI, Taiwan — On Tuesday nights, BX2AN sits near the Xindian River, motionless but for his thumb and middle finger, rhythmically tapping against two small metal paddles. They emit a sound each time his hand makes contact — from the right, a dit, or dot; from the left, a dah, or dash, the building blocks of the Morse code alphabet.
“Is anyone there?” he taps.
The replies come back in fits and starts: from Japan, then Greece, then Bulgaria. Each time, BX2AN, as he is known on the radio waves, jots down a series of numbers and letters: call signs, names, dates, locations. Then he adjusts a black round knob on his transceiver box, its screens glowing yellow in the dark.
There can be no doubt that this is his setup. That unique call sign is stamped across the front of his black radio set, scrawled in faded Sharpie on his travel mug and engraved in a plaque on his car dashboard. On the edge of his notepad, he’s absent-mindedly doodled it again, BX2AN.
In the corporeal world he is Lee Jiann-shing, a 71-year-old retired bakery owner, husband, father of five, grandfather of eight and a ham radio enthusiast for 30 years. Every week, he is the first to arrive at this regular meeting for Taipei’s amateur radio hobbyists.
[…]The self-governing island, about 100 miles east of China, is weighing wartime scenarios in the face of growing military aggression from its vastly more powerful neighbor. If cell towers are down and internet cables have been cut, the ability of shortwave radio frequencies to transmit long-distance messages could become crucial for civilians and officials alike.

CARACAS, Oct 26 (Reuters) – In July officials from Venezuela’s telecommunications regulator entered the Moda 105.1 FM radio station, in the northwestern state of Cojedes, accompanied by members of the national guard and demanding to see all the station’s licensing.
Hours later they stopped it broadcasting – making Moda one of at least 50 stations in Venezuela’s interior which have been closed so far this year by the Conatel regulator because it says they lack valid licenses.
The accelerated closures are a new step in efforts by the government of President Nicolas Maduro to control information and give state media hegemony over communications, journalist guilds and non-governmental organizations say, continuing a policy begun under his predecessor Hugo Chavez.

The BBC’s 100th anniversary has been marked in the town that enabled it to make nationwide radio broadcasts.
Opening on 27 July 1925, the Daventry Transmitter was the world’s first long wave transmitting station.
Known as 5XX, it was on Borough Hill in the Northamptonshire town and its first transmission was with the a poem called “Daventry Calling…”.
Sophie Good from the town’s museum said: “Daventry has got a strong affiliation with the BBC.”
The BBC chose the position so the transmitter could cover the maximum land area.
It brought the total audience within listening distance to 94% of the population.
When it opened, the poem by Alfred Noyes was followed by speeches from the postmaster general, external and the mayor of Daventry, introduced by Lord Gainford, BBC Chairman.
The then Prime Minister Stanley Baldwin sent a message, published in the Radio Times, which said he saw “Daventry as another milestone on the road to the social betterment of our people”. [Continue read at the BBC…]

Our friend Jeff White, General Manager of WRMI is trying to repair extensive damage to the WRMI antenna farm post hurricane Ian. A GoFundMe has been created to help WRMI with repair costs. Even small donations add up!
Jeff White provides the following details:
WRMI has a rich history of supplying news, information and entertainment to the world from our Okeechobee, Florida Transmitters.
Hurricane Ian damage to our antenna farm is so extensive, it has knocked us off the air to Europe and Africa.
We need your help to get us back on the air again to transmit to Europe and Africa news, information, religious programming and entertainment.
We have no insurance for the antenna farm due to the huge cost of insurance premiums.
We are desperately asking for help around the world to get us back on the air again to Europe and Africa. Your help is paramount to WRMI returning to the air in the many countries in Europe and Africa.
Your help will allow WRMI to rebuild the transmission towers destroyed by Hurricane Ian that are pointed towards Europe and Africa.
We thank you for your support of WRMI. Hurricane Ian knocked us down pretty hard. But we know with your help, we can rise back up and provide programming in many languages again to Europe and Africa.
General Manager WRMI
Running a radio station is, on the face of it, a straightforward technical challenge. Build a studio, hook it up to a transmitter, and you’re good to go. But what happens when your station is not a single Rebel Radio-style hilltop installation, but a national chain of transmitter sites fed from a variety of city-based studios? This is the problem facing the BBC with their national UK FM transmitter chain, and since the 1980s it has been fed by a series of NICAM digital data streams. We mentioned back in 2016 how the ageing equipment had been replaced with a modern FPGA-based implementation without any listeners noticing, and now thanks to [Matt Millman], we have a chance to see a teardown of the original 1980s units. The tech is relatively easy to understand from a 2020s perspective, but it still contains a few surprises. [Continue reading at Hackaday…]
This year’s IBC DRM virtual event, held on 6th September, was very well received by many participants world-wide. The much-awaited session on DRM receivers gave the listeners and viewers the opportunity to learn about new, hot off the press, receiver products and solutions in this sector.
A new cost-effective DRM solution developed by CML Microsystems in conjunction with Cambridge Consultants in the UK, is just one example. Their product is a multi-band broadcast DRM receiver module that makes it quick and easy for manufacturers to build DRM radio sets. The module supports DRM and analogue reception in the AM and VHF bands. Applicable IP royalties are included in the module price. The module also supports a remote controlled mode and thus can serve as the basis for full-featured DRM radio sets. The module is scheduled to be available to industry partners from Q1 2023.
Gospell from China presented their entire range of well-established and full-featured DRM receivers consisting of desktop and pocket radios, with support for EWF Emergency Warning Functionality and Journaline text service. In addition, Gospell unveiled their new car radio for easy integration, the Stereo Digital Radio Receiver GR-520. All models provide DRM reception across all DRM broadcast bands.
The Swiss company Starwaves announced three upcoming DRM receiver solutions: A complete and full-featured DRM and analogue AM/FM receiver module available to receiver manufacturers, with automotive-grade tuning and fast scanning across all DRM frequency bands and support for EWF Emergency Warning Functionality and Journaline text service. A first consumer receiver model built on this DRM module will be the W2401 desktop radio priced at €79. An even more advanced receiver at 99€ will in addition feature a built-in WiFi hotspot for web browser access to the DRM content. All Starwaves receivers can be enhanced with DAB+ functionality if required by a local market.
Starwaves also offers the DRM SoftRadio App for Android phones and tablets, which upgrades any device by connecting an analogue RF SDR dongle to a full-featured DRM receiver. The app is available in major app stores including Google, Huawei and Amazon.
Exciting DRM receiver solutions for professional applications and device manufacturers were presented by Fraunhofer IIS (Germany), such as the automotive receiver kit software SDR, and the DRM MultimediaPlayer Radio App as the basis of professional and consumer-grade radio implementations.
NXP, the leading, global semiconductor manufacturer, showcased their complete portfolio of automotive qualified suite of DRM chipsets for car receivers for all DRM broadcast bands.
Other companies from India, such as OptM and Inntot, as well as the South Korean manufacturer RF2Digital contributed to the pre-IBC DRM virtual event with videos presenting their solutions for DRM use in desktop radios, mobile phones and in cars.
CML Microsystems/Cambridge Consultants, Gospell, Starwaves and Fraunhofer IIS will also be present in Amsterdam during the IBC expo on the 10th September together with other key DRM members, such as BBC, Encompass, Nautel and RFmondial. IBC visitors participating in the two DRM sessions at the Fraunhofer IIS booth and at the Nautel booth will experience live demonstrations of the new DRM receivers and modules.

DARC reports on the planned introduction of an entry-level amateur radio license, it will be limited to just 10w EIRP in the 144 and 430 MHz bands but they can build their own equipment
A translation of the DARC post reads:
Today [June 7], the Federal Ministry for Digital Affairs and Transport presented the draft of a new amateur radio regulation that will bring some innovations for all radio amateurs.
The chairman of the DARC e. V. and the Round Table Amateur Radio (RTA), Christian Entsfellner, DL3MBG was pleased: “The new regulation implements long-standing requirements of the DARC and the Round Table Amateur Radio. Remote operation will finally be allowed in the future. The Ministry has also implemented our demand for a beginner class, which has existed since 2008.
This makes it much easier to get started with amateur radio.” While the existing classes E and A are raised in level due to the introduction of new topics from digital technology, class N focuses on operational knowledge, regulations and basic knowledge of the technology.
Holders of the new Class N will be allowed to transmit on 2m and 70cm with a maximum power of 10W EIRP. “The new entry-level class should offer access to amateur radio in particular to young people and older people in accordance with international requirements,” explains board member Ronny Jerke, DG2RON. The legally stipulated self-build right is not restricted, so even beginners can develop, set up and put into operation radio devices or hotspots themselves.
The exam will follow a cumulative system, e.g. B. is known from the US amateur radio test. First of all, the exam for class N is taken, which already contains all questions from the areas of operational knowledge and regulations. The technical test for class E and then for class A can then be taken.
“The examination catalogs developed by the DARC for the three classes are structured in such a way that the content and questions are not repeated, i. H. Content that has already been examined in a lower class no longer plays a role in the examination for a higher class. So all future radio amateurs go through the exams of class N, through E to class A. It should be possible to take all the exams in one day.
The previously unregulated remote operation has been included in the new amateur radio regulation. Holders of license class A may in future operate amateur radio stations remotely and also allow other radio amateurs to use class A. Another important innovation concerns the training radio operation, which will be possible in the future without a separate training call sign. Instead, adding the prefix “DN/” makes any Class E or Class A callsign a training callsign.
The RTA now has 4 weeks to comment on the draft regulation. The board and the departments of the DARC have already started to examine the text of the ordinance in detail and will report promptly.
Those of us who have had an interest in broadcasting over many years realize pretty soon that technology is constantly changing. The following relates to the situation where I live in Australia, but I suspect similar things are occurring in other parts of the world, and serve as a constant reminder that we live in a world of change.
When we were in our teens, we had radios that would tune AM and one or more shortwave bands. Hence many of us first heard interstate medium wave stations, and realised that signals there travelled further during darkness hours. Then we switched to SW1 or SW2 and often heard nothing. But persistence paid off and soon we were listening to stations that were in other countries! And when we connected a long wire to the antenna terminal signals improved dramatically. Wasn’t that amazing?
Somewhere in the 70s (I think) our TV stations brought in colour and that too was an amazing change to experience.
Then – somewhat belatedly for us in Australia – FM radio came along and gee the quality of the audio was outstanding! Even my late father was surprised by the clarity with which he could now listen to classical music on our nationwide dedicated ABC Classic FM station. FM also brought with it the introduction of “Community Radio” stations and in more recent years many other types of broadcasters.
Satellite TV came to us in the form of Foxtel: carrying so many different channels it was bewildering. When I realized that the events of 9-11 were telecast live on BBC World (and others), I too decided we should have Foxtel, as I have always been a “news nerd”.
By the late 1990s – having seen a hey day in probably the 60s and 70s – shortwave listening was rapidly becoming a thing of the past, and only hobbyists listened to SW: I remember being asked by another passenger when I was on a South Pacific cruise, what was that I was listening with out on deck? Was it some kind of computer? No, it was just a Sony SW55, and I was listening to Radio Australia.
Then, probably 5 years ago in Australia DAB+ radio was introduced, and whereas we previously had a choice of perhaps 10 to 15 AM & FM radio stations to tune to, suddenly we had a choice of these same stations on DAB radio (in major cities only), PLUS another 10 or 15! We have a phenomenal choice of what to listen to. From a technical view it was amazing to think that all the signals were coming from only one or two transmitters. For those of us with some technical interest it was for a while inconceivable that each station would not have its own transmitter.
Meanwhile, our TV systems have also become digitized in the last couple of years. Not just do we have perhaps three different channels for each commercial network, so 3 commercial networks are now providing probably 9 different programs. On top of that the Government broadcasters (ABC & SBS) have provided not just at least 3 TV channels each, but each of their numerous radio services is now also available on every TV set (eg BBC World Service is available 24/7).
About the same time, with higher internet speeds (ie better data transfers) being available, TV services and radio services are increasingly being streamed into our homes and to our mobile devices, with radio Apps promising they’re “free”, when in fact they do incur a data transfer impact/cost in whatever Internet plan one may have available. Many of the older generation probably don’t even realize what streaming video or sound means, but I think the younger generation is catching on.
Now, to my horror, my favourite DAB music station (“Buddha”) has been making announcements on air saying that the DAB service will be terminated from September 1st, and if I want to continue listening, I must tune in using that Company’s own “LiSTNR” app! Does this mean that listening to what comes over the ether will be a thing of the past? Will we be obliged to pay $x per annum to use a company’s streaming app just to be able to listen to their programs? Whatever is the world coming to?
Our country is, I suspect, very well catered for in terms of media services, and I wonder if we’ve done that too well. I also fear though, that those of us trying to push for reintroduction of shortwave services for remote Northern Territory areas (where streaming apps are a non sense), and for Australia to again broadcast into Pacific territories, may be fighting an uphill battle.
Anyone who has tried to find an AM/FM receiver in a big box retailer knows they are not as easy to find as they once were. It is little surprise then that the Consumer Technology Association expects fewer to sell this year. But at roughly five million units now sold each year, CTA expects that number to hold steady in the years to come, in part due to the role radio plays during emergencies.
“That category has stabilized,” said Rick Kowalski, Director of Industry Analysis and Business Intelligence at CTA. “It’s a low number relative to other categories, but there’s a steady demand, just in terms of people having an AM/FM radio for those situations where you might need a battery-powered radio as a backup.”
CTA forecasts 4.7 million traditional radio receivers will be sold this year in the U.S. That is six percent lower than the five million units sold in 2021. “Looking out in the next five years. It’s not going to get much lower than that,” Kowalski said in an interview.
CTA projects 24.5 million smart speakers will sell this year, or roughly five-times as many as traditional radio receivers. But in what may be a surprise to many, that estimate is actually two percent lower than the 25 million smart speakers that CTA says were sold last year. [Continue reading…]
ASHEVILLE, N.C. (WLOS) — The Asheville Radio Museum has added a new piece of history to its’ collection!
It’s a 1922 radio receiver built by an Asheville-based business.
The model HS2 radio the museum procured is only one of two known to exist.
Collector and restorer Robert Lozier found that it was the first name brand radio built in North Carolina.
News 13 spoke to the director of media communications Peter Abzug about why this radio is so significant.
“Having this radio here, in Asheville, where it was built is really significant,” he said. “It’s bringing it home. Although the company itself didn’t last for years and years, it did employ people and it was a significant part of Asheville’s history, and something we can be very proud of.”
Innovation is at the historic heart of Alabama Power, beginning with its founding in 1906 and Capt. William Patrick Lay’s vision of electrifying the state by harnessing the power of Alabama’s rivers.
But the company’s embrace of another cutting-edge technology, just 16 years after Alabama Power’s incorporation, is also historic.
One hundred years ago this year, on April 24, 1922, Alabama Power hit the airwaves with the state’s first operating radio station. WSY (an acronym for “We Serve You”) began broadcasting from rented space in a building on Powell Avenue in Birmingham.
The 500-watt AM station was initially designed as a company tool, to provide better communications among employees – especially those in the field and at remote generating plants. In fact, radio technology was so new – regularly scheduled radio programming in the United States started only in 1920 – Alabama Power engineers had to design and build most of WSY’s transmitting equipment.
“We began assembling the set … with intentions of using it for purposes of operation of the system exclusively,” wrote George Miller, the employee in charge of the station, in the July 1922 issue of the company’s Powergrams. “The broadcast feature came up, though, and materially changed our plans.”
Indeed, a month before the station went on the air, The Birmingham News published a do-it-yourself piece about “how to make your own radiophone receiving set” so local residents could pick up WSY when it began broadcasting.
Interest in the station was so strong that within weeks it began offering entertainment programs, according to “Developed for the Service of Alabama,” the centennial history of Alabama Power, written by noted historian Leah Rawls Atkins.
Dee Haynes, with the Alabama Historical Radio Society, recalled one story that underscores WSY’s popular embrace. Soon after WSY went on the air, earpieces began disappearing from the handsets of payphones all over Birmingham, apparently because people were swiping them to use in home-built receiving sets.

For 54 years, WCFW has been a beloved independently owned radio station on 105.7FM. But for lifelong Eau Claire resident Parker Reed, it has been more than that: it’s his family’s life, love, and legacy.
A catchy jingle – featuring the melody “WCFW, where FM means fine music” – came across a young radio station owner’s desk in 1969.
It was short, simple, and it worked. The owner paid $25 for it, and more than 50 years later that same jingle – which has aired thousands of times on 105.7FM radio – exemplifies the values of WCFW in Chippewa Falls and the couple who have owned it for over half a century: simplicity and consistency.
My grandparents, Roland and Patricia Bushland, have owned and operated WCFW since its inaugural broadcast on the airwaves on Oct. 20, 1968. Earlier this summer, they decided to end their 54-year stint in radio, selling the legacy station to Magnum Media – a Wisconsin-based media organization owned by Dave Magnum who now owns 25 radio stations across the state and will take over operations of the quaint, easy-listening station later this fall.
It’s a bittersweet moment – for the community, yes, but especially for our family, for whom the station has been an integral part of our lives for decades.
“It’s hard to not have mixed feelings about it, because it was our life for so long,” said my grandmother, Patricia Bushland. “When you start something, and you’re the only people who ran it all those years, you get attached to it. But after so many years, I’m thrilled to death that someone new is coming in, and we can finally take a break.”
When my grandfather, Roland, was young, he would draw pictures of radio towers during school – as his life too began with radio, front and center. My great-grandfather Roy Bushland owned and operated multiple Bushland Radio Specialties storefronts in Chippewa Falls and Eau Claire since the early 1930s – a business where my grandfather got his start in 1952 after he graduated Chippewa Falls High School as salutatorian.
