Discovery Dish Pre-launch: A Lightweight Dish And Feed For L-band Weather Satellites And Hydrogen Line Reception (RTL-SDR Blog)

For the past few years we have been working on finding the best way to help beginners get started with L-band weather satellite reception and basic radio astronomy. We have now come up with a solution that we’re calling the ‘Discovery Dish’ – a lightweight 65 cm diameter dish and active filtered feed set.

The Discovery Dish will be crowd funded, and we currently have a pre-launch page set up on Crowd Supply. So if you are interested, please visit the pre-launch page and click on the Subscribe button for updates.

Discovery Dish is a 65-cm diameter aluminum satellite dish and active filtered feed designed for receiving GOES HRIT, GK-2A LRIT, FengYun LRIT, NOAA HRPT, Metop HRPT, Meteor M2 HRPT and other weather satellites that operate around 1.69 GHz. The dish is designed to weigh under one kilogram, and it splits into three petals, making it easier to ship worldwide. The 1.69 GHz feed contains a built-in LNA right at the feed point, as well as filtering, which means that there is almost no noise figure loss from cables or connectors.

Note that the prototype images show an early non-petalized prototype with rough laser cut wind holes. The production version will obviously be a lot neater looking! […]

How China’s Propaganda Infiltrated Radio Stations in Europe (The Diplomat)

State-owned China Radio International is airing its content without attribution on commercial radio stations in Europe.

China has consistently and systematically pursued the dissemination of its narratives on the global stage, with the primary aim of shaping the international landscape to align with its strategic interests and ideological perspectives. These endeavors encompass a diverse array of tactics, including the acquisition of media enterprises, active engagement by Chinese ambassadors in both mainstream and fringe media outlets, the utilization of paid supplements, collaboration with pro-Kremlin media, and the steadily expanding presence of China across various social media platforms.

Recently, China Radio International (CRI), an official Chinese state media outlet broadcasting in multiple languages, has garnered attention for its establishment of partnerships with and provision of content to radio stations worldwide. Remarkably, CRI has effectively outsourced the production of China-related programming to local partners, often without transparently disclosing the sponsorship of content creation to the listeners. This strategy, known in Chinese as “borrowing a boat to go out on the ocean,” plays a pivotal role in laundering Beijing’s propaganda and fostering the acceptance of its messaging among local audiences.

One illustrative case of this approach within Europe involves two Czech radio stations, namely Radio HEY, a nationwide commercial radio station airing rock music, and Radio Color, which positions itself as “one of the last independent radios.” From 2019 to May 2023, these radio stations broadcasted a program titled “Barevný sv?t” (Colorful World), a nearly 30-minute segment aired six times a week, with the objective of acquainting Czech listeners with Chinese culture, language, and history.

Hackaday Prize 2023: A Software-Defined Radio With Real Knobs And Switches (Hackaday)

When cheap digital TV dongles enabled radio enthusiasts to set up software defined radio (SDR) systems at almost zero cost, it caused a revolution in the amateur radio world: now anyone could tune in to any frequency, with any modulation type, by just pointing and clicking in a computer program. While this undoubtably made exploring the radio waves much more accessible, we can imagine that some people miss the feeling of manipulating physical buttons on a radio while hunting for that one faint signal in a sea of noise. If you’re one of those people, you’re in luck: [Kaushlesh C.] has built a portable, self-contained SDR system with real knobs and switches, called SDR Dock 1.0.

The heart of the system is a Raspberry Pi running GQRX, an open-source SDR program that supports many different RF modules. [Kaushlesh] used an Airspy HF+ Discovery, a compact receiver that can work the HF and VHF bands, but it’s easy to modify the SDR Dock to accept other types like those ubiquitous RTL dongles. A seven-inch LCD screen with integrated speakers forms the main output device, with everything powered by a 10,000 mAh lithium-polymer battery. [Continue reading…]

Radio Nostalgia: Bob’s first radio

My Very First Radio

By Bob Colegrove

Sears and Roebuck Co., Silvertone, Catalog No. 8003, Model No. 132.818-1

I don’t remember much from 1949. I was seven years old and still in the first grade. I do remember being gifted a radio by my mom and dad on my birthday. It was a Sears and Roebuck Co., Silvertone, Catalog No. 8003, Model No. 132.818-1. I don’t really remember asking for it. I’m sure mom and dad did not have a clue as to how consumed I would become with radio over my lifetime. In truth, this was not the radio that got me totally absorbed, rather that function would be filled in 1958 by the Howard Radio Co. Model 308 combination MW/SW radio-phonograph console which had been relegated to the basement in favor of the TV set.

In 1949 television was on the cusp of success, and AM radio was still the one-way Internet of its time. I recall my mother listening to countless soap operas during the afternoon. The Howard was still in the living room and we listened to all the popular programs at night. Anyway, the Silvertone was mine. It took up residence in my room and I could independently explore the wonder of five local stations broadcasting in Indianapolis at that time. There were no parental guidance settings on the Silvertone, nor was there any need.

The Silvertone was not a world-class radio with all the sensitivity, bells and whistles I would later desire. Below WXLW, 950 kc it was deaf. It was, in fact, one tube short of an “All American Five.” However, one of its four tubes was dual function, if you counted the detector. It was what was called an “ac-dc” radio. This meant it could be powered by either 110 Vac or Vdc. Granted, there were a couple communities in the US which were still serviced by dc power at this late date, but that fact certainly did not warrant advertising. The whole thing always seemed to me no more than a marketing ploy on the part of manufacturers to cover for the lack of an expensive isolation transformer in the circuit. Given the fact that electrical standards of the time did not provide for polarized outlets and power cords, these things could be quite hot, and it’s amazing so many tinkers, myself included, are around to talk about it.

One Tube Short of an “All American Five”

The dial was very crude, and the tiny tuning knob swept all 107 available channels in a 180-degree twist of the variable condenser. My mom, always handy with a paint brush, took to marking favorite stations with a dab of nail polish. 1430 kc was WIRE and 1070 kc was WIBC. Perhaps she got the idea from Bill Halligan who used little red dots on the controls to indicate the setting that would likely produce some noise.

The printed media were sizeable and substantive in the 1940s. The Indianapolis Star’s morning edition for Friday, April 13, 1945 was particularly mournful as the U.S. woke up to the news that the president had died the day before. I was later given to understand that many stations broke from the normal schedule for a few days to play somber music. Notwithstanding, the first section still bore the quintessential hourly radio program schedule from 6 am to midnight for each of the four local stations. We always kept clippings of station logs for each day of the week.

My interest in baseball grew over the next couple years, and the Silvertone played an important role in my keeping up with the local AAA team. The static on a summer night was atrocious. Further, in those days, the broadcasters were not compelled to fill the air with chatter between pitches. There were no recitations of mindless statistics and no color commentators to describe the nuances of sliders and curve balls. Consequently, between pitches there were often long pauses of nothing but dead air. If you happened to tune in during a pause you had little idea where WISH, 1310 kc was on a hopelessly crude dial.

Most minor league broadcasters did not travel with the team. When the team went on the road, they used an old Model 15 clickety-clack Teletype machine in the studio. A local guy at the distant ballpark would observe a pitch or play, and quickly type a cryptic message on his Teletype. On the radio you would first hear the receiving Teletype spring to life in the studio as the message came in. The announcer would quickly interpret it, and then embellish the play with some excitement as best he could.

During those times, it was not too uncommon for the Teletype to suddenly go down during the game. What to do? An announcer was suddenly left to his own creativity to fill in airtime. Possible solutions were to describe the lengthy process of extricating a stray animal from the field, or a sudden cloudburst and consequential rain delay. An intrepid announcer went on as nothing happened, making up the play-by-play over the interval. Invariably, when the Teletype came back up, he found himself not quite in sync with the game and possibly a few runs behind. At that point the challenge was to patch in the necessary play and go on to complete the game to the satisfaction of an otherwise unsuspecting audience.

Well, after 73 years, I’ve seen my share of radios. In the meantime, the Internet has made it possible to DX the entire world at any time on a fifty-dollar Kindle – excellent fidelity, no interference, no noise, no fading. But, after all these years, I still cherish those static-filled ballgames and teletype machines heard on the Silvertone a long time ago.

Quietly Waiting for the Next Pitch

Radio Waves: Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Before There Was Radio: How Baseball Fans Followed Their Favorite Teams, 1912-1921 (SABR Century Research Committee)

If you were a major-league baseball fan in the 1910s, you were living at a time before commercial radio had come along. With no way to listen to the play-by-play at home (and no expectation that such a thing was even possible), you had to find other options when you wanted to know how your favorite team was doing. The best way, of course, was to go to the ballpark and watch the game in person, but not everyone could get the time off from work; there was no 40-hour workweek yet and putting in 50 or more hours a week was common in some jobs. And even if you had an understanding boss, there were still expenses to consider: By modern standards, tickets seemed cheap (even World’s Series seats ranged from 50 cents to $3), but keep in mind that the average worker’s salary was much less than what people earn today. For example, in 1915, the annual salary for teachers in most cities was less than $600,[1] and many other jobs paid no more than $700 a year.[2] Thus, attending a ballgame was reserved for special occasions.

Some fans who could not attend in person would go downtown and gather in front of the offices of the local newspaper, where they eagerly awaited the latest scores. The bigger cities often had a group of newspaper offices in close proximity to each other; in Boston and other large cities, this area was sometimes referred to as Newspaper Row. It became a place for fans to socialize, as everyone stood on the street in front of their favorite publication, hoping for good news about the game. When the newspaper received the latest scores from a telegrapher at the ballpark, a newsboy would write the information on a bulletin board, updating it every inning.[3] Some newspapers also had someone with a megaphone calling out the updates as they were received. In either case, the fans would cheer whenever the news was good, or express their disappointment when it wasn’t.[…]

VOA’s Bangla Service Ends Radio Broadcasts, Expands TV and Social Media Coverage (VOA)

Voice of America Bangla language service FM and shortwave radio transmissions officially end on July 17, 2021, after 63 years of serving Bangladesh and the Bangla-speaking Indian states of West Bengal, Tripure and Assam. Simultaneously, the service’s television and social media content will expand considerably, as these are platforms more heavily used by VOA Bangla’s 16 million weekly audience members.

“When VOA Bangla launched in January 1958, Bangladesh was known as ‘East Pakistan’ and it was a territory under martial law with no television or private radio,” said John Lippman, Acting VOA Programming Director. “VOA’s shortwave radio transmissions from outside the borders were a lifeline to the Bangla-speaking population for independent news and information.”

While the service’s shortwave radio audience is now less than one percent, VOA Bangla social media audiences have grown significantly in recent years. Engagement actions on the Twitter account have risen 54% over the previous year, while video views on Instagram are up 274% in the same period.

“Dozens of domestic television and radio stations compete for Bangla-speaking audiences, as well as an increasing number of digital sources,” Lippman noted. “As the demand for TV and online access to news in Bangladesh expands, VOA’s Bangla service program offerings need to be on the platforms its audience already is most active.”

“VOA Bangla radio broadcasts brought world events to its audiences since the days when radio was the primary news medium,” Acting VOA Bangla Service Chief Satarupa Barua told staff this month. “It was a staple in our upbringing, a household name. We will build on that reputation, increasing our presence on media that is now far more heavily used than short wave and medium wave radio.”

During the final days of its radio broadcasts, the service will broadcast retrospective programming, looking back at the changes in the country since 1958. “Because of our service’s history in Bangladesh, working at VOA has been the ‘dream job’ for many of us. With the coming changes, it will continue to be,” Barua added.

This change in radio programming will not affect broadcasts of “Lifeline”, a 30-minute daily radio program in the Rohingya language, spoken by Muslim refugees in Bangladesh who fled ethnic violence in Myanmar. Produced by the Bangla service, the program launched in July 2019.

Hatfield’s nearly 100-year-old broadcast station that revolutionised BBC radio (HertsLive)

Among its multiple accolades, Hertfordshire is home to one of the most important facilities in British broadcasting history – and it’s nearly 100 years old.

The Brookmans Park Transmitting station in Hatfield, Hertfordshire, was originally built by the BBC as the first of a network of regional dual transmitter stations, replacing the city-based ones from before.

The station has played a crucial part in the history of broadcasting in Britain. It was the first purpose-built twin transmitter station in the world that was capable of broadcasting two radio programmes simultaneously when it was completed in 1929.

The transmitter also played a role in the early development of television broadcasting.

This particular station was the first in the BBC’s adventurous scheme to bring existing radio reception to the whole of Britain.[…]

National Short Wave Listeners Club (Southgate ARC)

Ireland’s IRTS News report that meetings of the National Shortwave Club on Sunday evenings at 2000 on the Zoom platform will continue over the Summer months and they continue to attract around half of the membership of almost 120 most weeks.

A decision has been made to suspend the weekly Wednesday revision classes until it looks like an examination will be held within a reasonable time. Hopes are high that following next Thursdays Government announcement, an exam date will be published as soon as possible thereafter.

Interest in the new on-line classes which will begin in the autumn is already high and anyone interested is invited to reserve their place via email to ‘training at SWL.ie’
