Rti secures top ranking in global popularity among Japanese-language shortwave broadcast (RTI)

Radio Taiwan International (Rti) has been recognized in the 2024 JARL Ham Fair by securing first place in both the popularity ranking for shortwave stations and the best regular Japanese language broadcasting service.

The JARL Ham Fair is an annual event held during the summer, celebrating radio and broadcasting activities. Rti’s top rankings in both categories mark a major shift from its pre-pandemic standing, where Rti consistently ranked third.

Rti’s President Chang Jui-chang , who led a delegation to Japan last month to foster bilateral exchanges, expressed that this victory not only reflects Rti’s continuous efforts to improve its Japanese-language programming but also underscores the long-standing support and affection from its Japanese listeners.

One of the key developments this year was the resumption of the Double Ten National Day shortwave broadcast in Japanese, which further enhanced Rti’s service to its Japanese audience. Chang stressed that listeners are the lifeblood of any radio station, and Rti will continue its commitment to excellence in its Japanese programming to strengthen Taiwan-Japan ties and deepen mutual friendship.

Vatican Radio, a reference point for international broadcasting. History, facilities and broadcasts (exclusive interview) (FM-World)

Designed personally by Marconi, Radio Vaticana has been a key player in international broadcasting since the early 20th century, particularly in terms of technology. FM-world discussed this with Costantino Pacifici, who was Technical Director of the station for many years.

As the centennial of the radio approaches, the director of this publication asked us to do a quick overview of amplitude modulation stations. We had the opportunity to interview Centrale Milano, AM Italia, and OMItaliane.

But we immediately had the idea to talk about the most prestigious of all European radio stations: the station of Radio Vaticana.

With the help of RAI, we managed to secure a direct contact that led to this exclusive interview, focusing on the peak “broadcast” years of Vatican Radio: when broadcasts from the Holy See were joined by those from Santa Maria di Galeria, and when stereo transmissions began on 96.3 MHz. Here’s the report of the interview with Dr. Costantino Pacifici, which took place in mid-October 2024. [Continue reading…]

NASA is now talking to Voyager 1 with a radio that hasn’t been used since 1981 (BGR)

NASA can’t catch a break when it comes to Voyager 1, apparently. That’s because the US space agency has now revealed that the only thing keeping Voyager 1 communications running at the moment is a radio that hasn’t been used since 1981.

If that sounds like a bit of a nightmare, well, you aren’t wrong. But, it also isn’t the first stop that NASA has had to make on the nightmare train that has been its attempts to keep Voyager 1 working as optimally as possible over the past year.

In fact, this is just the latest in several Voyager 1 communications hiccups. The last hiccup began to show its ugly head in December 2023, when NASA revealed that Voyager 1 was sending back garbled data in its daily communications. That issue persisted for months, with some even believing that Voyager 1 was lost to us as far back as February. [Continue reading…]

The Strategic Advantage of European-based Shortwave Stations (Nexus.org)

[Abstract] The evolution from traditional tube-based shortwave transmitters to modern systems with Carrier Controlled Modulation represents a significant leap in broadcasting technology. While the old tube transmitters laid the groundwork for global communication, modern advancements have greatly enhanced the efficiency, clarity, and reach of broadcasts. Technologies like CCM modulation, directional curtain array antennnas and modern digitally controlled transmitters are pivotal in today’s communication landscape, ensuring that broadcasters can deliver high-quality audio content across the digital divide and to interested targets more reliably and efficiently, especially across vast distances. This slow shift in technology not only preserves the integrity of the transmitted message but also optimizes the use of energy and bandwidth, setting the stage for further innovations in global broadcasting, energy conservation and sustainability.

Scientists Seeking Life on Mars Heard a Signal That Hinted at the Future (NY Times)

Please note: this article is behind a paywall and you will need a subscription to read. We include a link to this article in Radio Waves because of its relevance in radio history.

In 1924, a radio receiver built for the battlefields of World War I tested the idea that humans were not alone in the solar system, heralding a century of searches for extraterrestrial life.

At sunset on a late summer weekend in 1924, crowds flocked to curbside telescopes to behold the advanced alien civilization they believed to be present on the surface of Mars.
“See the wonders of Mars!” an uptown sidewalk astronomer shouted in New York City on Saturday, Aug. 23. “Now is your chance to view the snowcaps and the great canals that are causing so much talk among the scientists. You’ll never have such a chance again in your lifetime.”

During that weekend, Earth and Mars were separated by just 34 million miles, closer than at any other point in a century. Although this orbital alignment, called an opposition, occurs every 26 months, this one was particularly captivating to audiences across continents and inspired some of the first large-scale efforts to detect alien life.

Pi-Pico Software Defined Radio

Many thanks to SWLing Post contributor, Pete Eaton, who writes:

“A Homebrew Shortwave Receiver can not get much simpler than this:”

Pi-Pico RX – Breadboard Version

A couple of years ago, I built a basic yet capable radio receiver using a Pi Pico, and while I originally designed a custom PCB for it, this time I’m building an even simpler and cheaper version that can be built on a breadboard using (mostly) through-hole components.

I wanted to build a very minimal (but useful) design that I could use as a platform for experiments, tweaks and upgrades.

If you are interested in the original design or want to find out more about the technical details you can find all the info here. Most of the technical details are the same, so I will focus on the new features and improvements here. [Click here to continue reading…]

USAGM Cancels Lease for Saipan Site (Radio World)

Move is in line with letting its Marianas shortwave transmitters go dark

The U.S. Agency for Global Media has informed the Commonwealth of the Northern Mariana Islands’ Department of Public Lands that it will terminate its long-term lease on Aguiguan Point.

Aguiguan Point is home to the Saipan portion of the Robert E. Kamosa Transmitting Station, which the agency confirmed last week was being shuttered. The shortwave site has been used since the mid-1990s to beam Voice of America and Radio Free Asia broadcasts across the Pacific.

According to a report in the Saipan Tribune, Department of Public Lands Secretary Teresita Santos confirmed that USAGM had informed the department it would not seek renewal of the lease, but no timeline for terminating the lease was provided. Santos was quoted as saying that once the lease is terminated, the department would issue a request for proposals for the site. [Continue reading…]

Hungarian National Arrested on Charges of Conspiring to Export U.S. Military-Grade Radios to Russian Government End Users (Department of Justice)

The Justice Department unsealed a criminal complaint charging Hungarian national Bence Horvath with violations of U.S. export controls targeting Russia, including by conspiring with others to illegally export U.S.-origin radio communications technology to Russian government end users without a license. Horvath is charged by complaint with one count of conspiring to violate the Export Control Reform Act of 2018 (ECRA). He was arrested on arrival at San Francisco International Airport in San Francisco, California, on Aug. 23.

“As alleged, the defendant attempted to purchase military-grade radios for Russian entities using a multinational procurement chain to evade law enforcement,” said Assistant Attorney General Matthew G. Olsen of the Justice Department’s National Security Division. “The Justice Department remains committed to disrupting and holding accountable criminal networks that continue to fuel Russian aggression abroad and threaten our collective security.”

“Targeting illicit global procurement networks that operate in the shadows to equip the Russian government is of the highest priority to BIS,” said Assistant Secretary for Export Enforcement Matthew S. Axelrod of the Commerce Department’s Bureau of Industry and Security (BIS). “As Horvath’s arrest demonstrates, it doesn’t matter where in the world you operate – when the United States believes your conduct violates our export laws, we take action.” [Continue reading…]

Radio Apocalypse: HFGCS, The Backup Plan For Doomsday (Hackaday)

To the extent that you have an opinion on something like high-frequency (HF) radio, you probably associate it with amateur radio operators, hunched over their gear late at night as they try to make contact with a random stranger across the globe to talk about the fact that they’re both doing the same thing at the same time. In a world where you can reach out to almost anyone else in an instant using flashy apps on the Internet, HF radio’s reputation as somewhat old and fuddy is well-earned.

Like the general population, modern militaries have largely switched to digital networks and satellite links, using them to coordinate and command their strategic forces on a global level. But while military nets are designed to be resilient to attack, there’s only so much damage they can absorb before becoming degraded to the point of uselessness. A backup plan makes good military sense, and the properties of radio waves between 3 MHz and 30 MHz, especially the ability to bounce off the ionosphere, make HF radio a perfect fit.

SDR: The Next Level of Shortwave Radio Listening (Radio World)

Where have these things been all my life?

There is a new breed of RF receivers known as software-defined radios, and they are revolutionizing the way in which people listen to shortwave (SW) radio, or indeed any form of radio broadcast.

SDRs combine plug-in radio receiver dongles/boxes with personal computers, with the computer serving as the user interface. What makes this interface so useful is that the listener’s screen displays a wide swath of the bandwidth being tuned to, with each station’s signal shown as a visual vertical line that moves and grows/shrinks with its signal strength.

In other words, the listener can literally see what is happening across the band in real time, rather than having to turn the dial or push the Up/Down scanning buttons on a conventional shortwave radio, checking one station at a time. [Continue reading…]

FCC Hits 13 Landlords in NYC Metro Area With Pirate Letters
Enforcement sweeps allege illegal FM broadcasts within the last year (Radio World)

The FCC Enforcement Bureau’s New York Office has sent 13 different landlords in New York City, Rockland County, N.Y., and northern New Jersey the “pirate letter” after discovering alleged illegal FM broadcasts originating from their properties.

The NYC metropolitan area is notoriously known for pirate operators. Each of the 13 cases outlined below occurred within the last year.

According to FCC Rules, the landlords could face a fine of nearly $2.4 million if the commission determines that an illegal broadcast continued from a property they own or manage after receiving notice. [Continue reading…]

WBCQ: A One-of-a-Kind Shortwave Radio Station (Radio Waves)

A brokered programming business model has kept the station on the air for 26 years

There are all kinds of shortwave radio stations in the world, but WBCQ seems unique.

Allan Weiner at the foot of the rotatable antenna installed in 2018.
Located in Monticello, Maine, WBCQ is an up-to-500,000 watt shortwave powerhouse that covers the world via 7.490 MHz, 9.330 MHz, 5.130 MHz, 3.265 MHz, and 6.160 MHz — depending on the time of day, to maximize signal propagation by bouncing off the ionosphere.

The same rural broadcasting center and antenna/transmitter site is also home to local stations WXME(AM) — carrying talk and rock music on 780 kHz with a translator on 98.3 MHz — and WBCQ(FM), airing classic country on 94.7. [Continue reading…]

75 reasons to celebrate WCPO-TV’s 75th anniversary (WVXU)

From Uncle Al to Al Schottekotte, from Sports of All Sorts to recorded “Scrippscast” newscasts, and from Sherry Hughes and Paul Dixon, WCPO-TV has provided many memorable moments and innovations in Cincinnati TV history since 1949.

Cincinnati’s third television station, WCPO-TV, has many impressive firsts in local TV history dating back to its very first minutes on the air on July 26, 1949.

WCPO-TV debuted at noon on Channel 7 (before the federal government reallocation moved it to Channel 9) with WCPO-AM radio disc jockey Art Jarrett. WLWT-TV — the city’s first TV station then in its 16th month of operation — didn’t air programming until 4 p.m. WKRC-TV, which debuted in April 1949, was dark until 6 p.m.

The station’s official dedication was broadcast at 7:45 p.m. with Gov. Frank Lausche at Crosley Field before Channel 7 broadcast the Reds-Boston Braves game, a simulcast with Waite Hoyt’s radio call on WCPO-AM (now WDBZ-AM, 1230 “The Buzz of Cincinnati”). [Continue reading…]

An Antenna To Throw You For A Loop (Hackaday)

It is one of Murphy’s laws, we think, that you can’t get great things when you need them. Back in the heyday of shortwave broadcasting, any of us would have given a week’s pay for even a low-end receiver today. Digital display? Memory? Digital filtering? These days, you have radios, and they aren’t terribly expensive, but there isn’t much to listen to. Making matters worse, it isn’t easy these days to string wires around in your neighborhood for a variety of reasons. Maybe you don’t have a yard, or you have deed restrictions, or your yard lacks suitable space or locations. This problem is so common that there are a crop of indoor antennas that seem attractive. Since I don’t often tune in shortwave and I don’t want to have to reset my antenna after every storm, I decided to look at the Tecsun AN-48X along with a YouLoop clone from China. Let’s start with the Tecsun. [Continue reading…]

Ask Hackaday: Is Shortwave on Life Support? (Hackaday)

Between World War II and Y2K, shortwave listening was quite an education. With a simple receiver, you could listen to the world. Some of it, of course, was entertainment, and much of it was propaganda of one sort or another. But you could learn a lot. Kids with shortwave radios always did great in geography. Getting the news from a different perspective is often illuminating, too. Learning about other cultures and people in such a direct way is priceless. Getting a QSL card in the mail from a faraway land seemed very exciting back then.

Today, the shortwave landscape is a mere shadow of itself. According to a Wikipedia page, there are 235 active shortwave broadcasters from a list of 414, so nearly half are defunct. Not only are there many “dead” shortwave outlets, but many of the ones that are left are either not aimed at the world market or serve a niche group of listeners. [Continue reading…]

In 1924, a magazine ran a contest: “Who is to pay for broadcasting and how?” A century later, we’re still asking the same question (NiemanLab)

Radio Broadcast received close to a thousand entries to its contest — but ultimately rejected them all.

After yet another day reading about audio industry layoffs and show cancellations, or listening to podcasts about layoffs and show cancellations, I sometimes wonder, “With all this great audio being given away for free, who did we think was supposed to pay for it all?”

I find some consolation in the fact that that question is more than a century old. In the spring of 1924, Radio Broadcast posed it in a contest called “Who is to Pay for Broadcasting and How?”The monthly trade magazine offered a prize of $500 (more than $9,000 in today’s dollars) for “a workable plan which shall take into account the problems in present radio broadcasting and propose a practical solution.”

The need for such a contest more than 100 years ago is revealing enough, but the reaction of the judges to the prize-winning plan turned out to be even more so — and it says a lot about why business models for audio production and broadcast remain a struggle. [Continue reading…]

The Rich History of Ham Radio Culture (The MIT Press Reader)

Drawing on a wealth of personal accounts found in magazines, newsletters, and trade journals, historian Kristen Haring provides an inside look at ham radio culture and its impact on hobbyists’ lives.

Every night thousands of men retreat to radio stations elaborately outfitted in suburban basements or tucked into closets of city apartments to talk to local friends or to strangers on the other side of the world. They communicate by speaking into a microphone, tapping out Morse code on a telegraph key, or typing at the keyboard of a teletypewriter. In the Internet age, instantaneous, long-distance, person-to-person communication seems ordinary. But amateur radio operators have been completing such contacts since the 1910s. The hobbyists often called “hams” initially turned to radio for technical challenges and thrills. As the original form of wireless technology became more reliable and commonplace in the 1930s, ham radio continued as a leisure activity. Hams formed a community through the same general practices of other social groups. They set conditions for membership, established rules of conduct, taught values, and developed a specialized vocabulary known only to insiders. What made hams’ culture different was its basis in technology. In her book “Ham Radio’s Technical Culture,” excerpted below, historian of science and technology Kristen Haring draws on a wealth of personal accounts found in radio magazines and newsletters and from technical manuals, trade journals, and government documents to illustrate how ham radio culture rippled through hobbyists’ lives.

CarnationFM: A Decentralized Radio Playing Songs With Encrypted Hidden Messages (Coin Desk)

CarnationFM emerged from EthBerlin 2024 and won the award for Best Social Impact.

Berlin, Germany: A music-focused radio FM which allows songs to act as a transport vessel for hidden messages has emerged from EthBerlin 2024. CarnationFM was created by five hackers and a mentor as a defensive, decentralized and encrypted communication tool enabling private messaging that safeguards anonymity.

The project, which won the award for the Best Social Impact at EthBerlin 2024, is focused on creating real world use cases factoring in privacy in the aftermath of the Alexey Perstev verdict. Alexey Perstev, one of the co-founders of Tornado Cash, was sentenced to 64 months in prison in May.

The verdict rattled the decentralized community because it suggested that a coder could be held responsible for everything that happens using that code. Perstev was found guilty because his open-source mixer Tornado cash allowed North Korea’s infamous Lazarus group to launder millions in crypto. [Continue reading…]

Nation’s last Morse code station comes back to life on annual ‘Night of Nights’ in Point Reyes (The Mercury News)

KPH, established in Point Reyes and Bolinas in 1913, will exchange messages with Morse code enthusiasts around the world

On July 12, 1999, the nation’s final message in Morse code was sent out to sea from a remote Bay Area radio station. The end of an era, the room’s mood was mournful. Grizzled old men wept.

“We wish you fair winds and following seas,” it said, offering a seafarers’ traditional farewell in a staccato stream of dots and dashes. And then the station went silent.

But every July 12, the golden age of maritime radio comes back to life. [Continue reading…]

Navy researchers ask Envisioneering to support over-the-horizon radar that relies on HF radio signals (Military Aerospace Electronics)

Over-the-horizon radar typically uses HF radio signals at frequencies between 2 and 30 MHz to reach beyond the horizon in open-ocean areas.

WASHINGTON – U.S. Navy researchers needed to help develop a new prototype High Frequency (HF) over the horizon (OTH) radar system. They found a solution from Envisioneering Inc. in Alexandria, Va.

Officials of the Naval Research Laboratory (NRL) in Washington announced a $45.4 million contract to Envisioneering Inc. on Monday for design, development and integration of a mobile over-the-horizon radar (MOTHR).

Over-the-horizon radar typically uses HF radio signals at frequencies between 2 and 30 MHz to reach beyond the horizon in open-ocean areas. HF signals bounce off the ionosphere to achieve long distances and operate beyond the curvature of the Earth.

Envisioneering will work alongside the NRL research team to support key areas such as refinement of system requirements; system and subsystem design; mechanical analysis; specifying and procuring long-lead items; integration; testing; and signal processing. [Continue reading…]

Electric ‘Ripples’ in the Resting Brain Tag Memories for Storage (Quanta Magazine)

[Note: this is not a radio article, but mentions a connection to ham radio.]

György Buzsáki first started tinkering with waves when he was in high school. In his childhood home in Hungary, he built a radio receiver, tuned it to various electromagnetic frequencies and used a radio transmitter to chat with strangers from the Faroe Islands to Jordan.

He remembers some of these conversations from his “ham radio” days better than others, just as you remember only some experiences from your past. Now, as a professor of neuroscience at New York University, Buzsáki has moved on from radio waves to brain waves to ask: How does the brain decide what to remember? [Continue reading…]

Radio Sunshine – Niue (Now streaming)

SWLing Post Tracy Wood writes with the following note:

The Internet audio stream for Niue’s Radio Sunshine now appears to be active, albeit not 24×7. The station operates locally on FM but formerly was a top AM DX target.

Niue is a self-governing dependency of New Zealand.

On the technical side, the audio stream URL unfortunately appears to be somewhat dynamic as it’s using a “radioplayer” Javascript. The player (and stream) can be found at the tvniue.com homepage, the official radio/TV corporation of the island.

Fans of Oceania radio can add this one to other area countries that stream such as Nauru, Kiribati, and Samoa.

Switzerland to end 2024 with an analog FM broadcast-killing bang (The Register)

Time to upgrade that receiver if you’re one of the few Swiss that still don’t have one able to receive DAB+ signals

Swiss radio listeners will soon have to toss out their old sets, as the country plans to end analog FM broadcasting on December 31, 2024, in favor of a total conversion to digital.

The move has been a long time coming in Switzerland, which has largely already transitioned to Digital Audio Broadcasting (DAB+, an evolution of standard DAB that was designed to address early issues). More than 99 percent of the country have access to a DAB+-compatible receiver and fewer than 10 percent of radio signals in the country still being broadcasted in analog FM, according to the Swiss Broadcasting Corporation.

AM Radio for Every Vehicle Act to Receive Minor Technical Update (Radio World)

There will be no substantive changes to the legislation

A bill in the House of Representatives that would mandate AM capability in new vehicles is about to be revised, according to a person familiar with the developments.

New information indicates that one of the original co-sponsors of the bill, Rep. Frank Pallone (D-N.J.), plans to introduce an amendment to the bill (H.R. 8449). Changes would only include minor technical updates.

The planned amendment to the AM Radio for Every Vehicle Act comes on the heels of last week’s last-minute cancellation of a planned vote by the House Energy and Commerce Committee, which could have advanced the legislation to the full House for a vote. [Continue reading…]

Would AM Mandate Force Carmakers to Scrap Safety Features?

Opponents play up the possibility that carmakers would have to choose

If Congress requires AM radio in new cars, vehicle manufacturers might have to drop safety features instead.

That’s the message from opponents of the proposed law in Congress. A guest commentary published by Automotive News restates the key points that opponents have been making since the legislation was introduced; but their blunt emphasis on a possible tradeoff with important safety features seems notable.

“To accommodate analog AM radio as a primary design requirement, certain carmakers may need to scrap advanced safety features, with engineers having to prioritize outdated technology over current or future safety innovations,” they wrote. [Continue reading…]
