BBC Bangla issues its final broadcast after 81 years (Global Voices)

The new year was bittersweet for many Bengali radio fans this year, as listeners learned that BBC Bangla Radio would stop airing on December 31, 2022, after an 81-year run. In the years leading up to its closure, two sets of half-hour programs were aired each day on shortwave and FM bands in the morning and evening. The webpage was archived as soon as the night programs finished on the last day, closing the chapter on the iconic British Broadcasting Channel segment.

In an effort to cut spending and follow media trends, BBC World Service will be pivoting toward increased digital offerings, leading them to shut down radio-wave broadcasts in several international languages. BBC Bangla will continue as a digital-only multimedia channel in a limited capacity.

Bangla (Bengali) is the seventh most spoken language by the total number of speakers in the world. Spoken by approximately 261 million worldwide, it is the primary language in the region of Bengal, comprising Bangladesh (61 percent of speakers) and the Indian state of West Bengal (37 percent of speakers).

Ham Radio’s Paper Trail (Disquiet)

A new book from Standard Manual

A trove of more than 150 such QSL cards, formerly owned by an operator who went by the call sign W2RP, was obtained by designer Roger Bova. Bova then collaborated with the book imprint Standards Manual (full disclosure: I’ve done some work with the publisher’s parent company, the design firm Order) to collect them into a handsome volume. I’m reprinting some of the images here, with the publisher’s permission.

W2RP, as it turns out, was no ordinary “amateur.” W2RP was the late Charles Hellman, who lived to the age of 106. The cards obtained by Bova are both a visual map and a physical manifestation of the numerous conversations he participated in over what is said to have likely been the longest continuously active ham license, more than 90 years. Hellman first obtained his license at the age of 15. Some historical context: he was born in 1910, one year after the Nobel Prize in Physics went to Guglielmo Marconi and Karl Ferdinand Braun for their pioneering work in radio. Hellman himself taught physics in Manhattan and the Bronx, and two of his students reportedly went on to win the Nobel in physics. (More on his remarkable life at qcwa.org.) [Continue reading…]

GUEST COLUMN: Vintage radios dial up a lesson in life (OrilliaMatters.com)

‘It would be the understatement of the year to say there were a lot of radios and radio-related paraphernalia’ at Chevy Halladay’s Orillia home

As I crossed the porch toward the side door of Chevy Halladay’s century home near Orillia, I had no idea what to expect. The door opened before I could knock, Chevy extended his arm to shake hands, and welcomed me into his home.

To my right was a small closet where I could hang my coat. I missed the hook, sending the coat to the floor. I was much too distracted to waste another second on hanging it neatly. To my left was a huge, free-standing mid-50s radio and TV tube testing machine stacked high with rare tubes, a six-foot-tall floor clock and radio with a built-in turntable, and a vintage Coca Cola vending machine. Each piece had been carefully restored for appearance and functionality.

A single step further into the room brought Chevy’s, and his wife Maggie’s, kitchen counter into view. Atop it were two partially restored radios, one a jumble of dusty tubes and a speaker early into the process, the other a spectacular and rare wood-cased Stromberg-Carlson, being prepared for final refinishing before being shipped to a friend in Bethesda, Maryland.

Don’t misunderstand. This was no hoarder’s enclave or home transformed into a ramshackle workshop. Their house is immaculate, and Maggie is on-side with Chevy’s mono-themed interior decorating style, yet it would be the understatement of the year to say there were a lot of radios and radio-related paraphernalia everywhere.

There was not an inch of wall that wasn’t shelved to display countless historic radios, or covered with hanging wall clocks that were used as promotional items by radio companies, steel promotional signs, framed advertising posters, or other memorabilia. [Continue reading…]

Voice from the East – an original hour long documentary from Monitor Production in Sound

Between 1970 and 1991 a woman, never named and with a sonorous antipodean accent, could be heard broadcasting some of the most extraordinary communist propaganda ever heard amongst the radio stations of the former socialist countries.

Radio Tirana broadcast from Albania – at one time Europe’s most secretive and closed country.

The transmissions were the source of enormous fascination for one 13 year old boy who listened to the programmes at bath time, with increasing amazement.

53 year old journalist John Escolme was that 13 year old.

We join his journey to track down the mystery broadcaster who not only recalls her life on-air, but her own extraordinary personal story – one that took her from remote New Zealand to an eccentric Stalinist regime rarely visited by anyone from the west. [Click here for original article.]

Radio Martí news: Migrants land by Keys broadcasting tower promoting Cuban democracy (Miami Herald)

Washington maintains a waterfront radio tower in the Florida Keys to broadcast programming aimed at encouraging democracy and press freedom in Cuba, and on Sunday that area in Marathon was the landing spot for a group of migrants fleeing the island. A boat of 25 migrants arrived on the shores of Sister Creek, home to a Radio Martí transmission station on Sunday morning, said Adam Hoffner, assistant chief patrol agent for U.S. Customs and Border Protection’s Miami operations. The landing was one of two known migrant arrivals in the Keys on Sunday, with another 28 Cubans arriving on private property in Key Largo. While the government-run broadcasting agency targets Cuban listeners with Spanish programming, Radio Martí reports typically discourage the kind of voyage that reportedly landed some Cubans on or near Martí property, said Tomás Regalado, the former Miami mayor who also recently ran the agency that oversees Radio and TV Martí. “Historically, the migrant situation was something that was treated as news,” Regalado said. “But with the caveat that it’s a very dangerous trip and not recommended.” [Read more here…]

Ukraine Uses Off-The-Shelf Electronics To Target Russian Communications (Forbes)

A nonprofit organization based in the U.S. is supplying Ukrainian forces with advanced electronic warfare gear assembled from simple off-the-shelf components. The secret is a new technology known as Software Defined Radio (SDR) which can locate Russian radio emitters, from command centers to drone operators. Previously this sort of capability required expensive, high-grade military equipment.

Serge Sklyarenko says his organization, American Ukrainian Aid Foundation, based in New York, is supplying Ukrainian intelligence with a number of the versatile SDR radio kits.

“The beauty of them is they are software defined, meaning they can be reprogrammed in the field to suit a multitude of use cases,” Sklyarenko told me.

In a traditional radio set, the signal from an antenna is processed by dedicated hardware – amplifiers, filters, modulator/demodulators and other components. This means that each radio set is dedicated to one particular type of radio signal, whether it is a 5G cellphone, AM radio, digital television or WiFi. In Software Defined Radio, the only dedicated hardware is the antenna. All the signal processing is carried out digitally with a computer. Simply by changing the programming, an SDR can extract the signal for cellphone, radio, Bluetooth, or any other defined waveform. One device can do everything. [Continue reading…]

Innovation on Morse Code for the US Military (SOFREP)

On January 10, 1991, the U.S. Army Intelligence School Devens (USAISD) introduced the Basic Morse Mission Trainer to the 98H Morse intercept operator and 98D emitter identifier/locator advanced individual training courses. This system revolutionized the training of Morse code copying skills for both students and instructors, reducing course attrition, and turning out better trained operators faster. Continue reading

A DXpedition to East Sandy

Many thanks to SWLing Post contributor, Don Moore–noted author, traveler, and DXer–for the following guest post:


A DXpedition to East Sandy

By Don Moore

When I was in college over forty years ago, seven of us had a small DX club in central Pennsylvania. A couple of times a year we would gather at the house of one of our parents for an all-night DX session. We shared tips and ideas, had fun, and always heard some new DX. Good DX can happen anywhere if conditions are right and most of mine over the past fifty years took place at wherever home happened to be at the time. But most of my best experiences and best memories of DXing were not made at home. They were made by getting together to DX with other hobbyists such as we did back in college.

Nowadays when I get together to DX with other hobbyists it’s to go on a DXpedition, which is nothing more than taking your receiver to a place where DXing will be better than at home because there’s less noise and you can erect better antennas. Simple DXpeditions can be done from cars. My old friend Dave Valko used to go on what he called micro-DXpeditions. He drove to a remote spot in the mountains not far from town, laid out a few hundred feet of wire, and then DXed from his car for a couple hours. He frequently did this around dawn and around sunset and got some great DX. I know several other DXers that do this today, either at countryside locations or in large parks.

I’ve done micro-DXpeditions a few times. It’s fun but it always lacks an important element: other DXers. For me, the best DXpeditions aren’t just about hearing interesting stuff (although that is very important). They are also about sharing the hobby with other interested friends. And the best way to do that is to go on a real DXpedition with them.

For three years in a row prior to the pandemic a group of eight of us had rented a lodge in rural central Ohio for an annual DXpedition. Covid shelved our plans for 2020 but by the summer of 2021 we were all looking forward to a fourth DXpedition in September. Then another wave of covid swept across the country and we canceled a few weeks before the event. Fortunately, the worst of those days are behind us and we finally had our fourth DXpedition the first week of October of this year. Unfortunately, only five of us could make it – Ralph Brandi, Mike Nikolich, Andy Robins, Mark Taylor and I.

For four nights our DXpedition home was the same place in western Pennsylvania that we had canceled at in 2021. The location was a rural house on the bluffs overlooking the Allegheny River near the old East Sandy railroad bridge (now a hiking trail). It’s always a gamble going to a new place chosen solely based on the AirBnB listing and other information found online. But this site had all the appearances of being a good place to DX from. The pictures and Google satellite view showed that there were trees around the house and large nearby open fields surrounded by woodland. The terrain was relatively flat when viewed on 3D satellite view. We would have plenty of space for a variety of antennas. Furthermore, it didn’t look to be a noisy location. The nearest neighbor was over a quarter mile to the south and because the house was the last one on the road that powerlines stopped at the driveway. I couldn’t have done much better if I had designed the location myself.

ANTENNAS

Good antennas are the most important part of any DXpedition and erecting them is usually the most time-consuming part of set-up. Still, you never really know what’s going to fit until you’re there. I arrived at 2 p.m. and Mark pulled in a few minutes later. We immediately walked the grounds and were pleased with what we saw. Ralph arrived while we were laying out the first antenna. Mike and Andy arrived later in the afternoon in time to help finish up.

Our DXpedition antenna farm consisted of two delta loops, a DKaz, and two BOGs. The delta loops used Wellbrook ALA-100LN units and are as I described a few years ago in my article on radio travel. These are easy to erect and are good all-around antennas for anything below 30 MegaHertz. The DKaz (instructions here) is a rather complex-to-build antenna designed for medium wave. Ralph uses one at home which he had taken down for the summer to make yard work easier. He brought the pieces and put it up by himself. The two BOGs (Beverage-on-the-ground) were a 300-meter wire to the northeast and a 220-meter wire to the north. Beverages are good for long wave, medium wave, and the lower shortwave frequencies.

Balazs spots vintage radios in film and in a Budapest pub!

Many thanks to SWLing Post contributor, Balázs Kovács, who writes:

Hi Thomas,

Happy New Year! Some pictures in two topics:

1.) First, a nice Zenith H511 Consoltone (MW) got a few seconds of screen time recently in the fourth episode of the third (final) season of “His Dark Materials” series:

 

2.) At the end of December in an old pub in Budapest (Helvecia) I ran into some more or less old radios as a part of the eclectic decoration. Since these are partly Eastern European, they may be less well known elsewhere (deep in the basement, so even if they were still functioning, not many radio signals would reach them anymore):

With best regards,
Balazs

Wow! I love those pub radios!  I especially love the dial markings on the R 926 A!

Thank you for sharing these images, Balazs!

Frans’ meditation at 198kHz with the Siemens REL 445 E311 b1b

Many thanks to SWLing Post contributor, Frans Goddijn, who writes:

Hi Thomas!

Yesterday was dark and rainy and as I switched on my old Siemens REL 445 E311 b1b there was an interesting snippet of program on BBC4 with a meditation that nicely fitted the afternoon’s atmosphere:

Best regards,

Frans

Wonderful–thank you for sharing that with us, Frans! A warm sound emanating from your Siemens receiver on such a rainy day. Beautiful.
