Long wave radio fans mourn fading frequencies (BBC News)

As he turned the dial gently but purposefully, the sound of people speaking in foreign languages and the lilt of unfamiliar music burst through a haze of crackle and buzz.

Clint Gouveia was only about seven years old at the time, listening to long wave radio in bed, late at night.

“I could hear all these voices from far away,” he recalls. “It inspired me to want to see the world when I got older, to travel, which eventually I did.”

Back then, in the late 1970s, there were dozens of long wave stations broadcasting. Now, only a handful are left. Among them are those in Denmark and Iceland – but they are due to shut by the end of 2023 and during 2024, respectively.

The BBC still broadcasts Radio 4 on long wave as well as on digital radio, FM, and online. However, separate scheduling of BBC radio programmes on long wave will end in March next year – for example Test Match Special will not be available on long wave. The long-term future of the BBC’s long wave output is far from certain.

The only other remaining broadcasters in the world using the long wave band are those in Romania, Poland, Algeria, Morocco and Mongolia.

“The band is basically almost dead,” says Mr Gouveia, who enjoys listening to radio stations from his home in Oxford. “It all feels a bit sad, really.” He adds that, when a long wave station shuts, he makes an effort to record its last moments. [Continue reading…]

The Return of the Prodigal Shack? (Sound and Vision)

I remember it like it was yesterday. I was consulting for a car company and I needed to A/B two tweeters. I dashed over to the nearest RadioShack and picked up a speaker-switching box. Crazy to think about it now – a brick-and-mortar store selling something like that. Of course, RadioShack is just a distant memory now. Or is it? Is RadioShack making a comeback?
Founded in 1921 to sell amateur radio gear, RadioShack grew to achieve genuine ubiquity. In its prime, there were over 5,000 stores in the U.S. and another 3,000 in other countries. The company boasted that it was the biggest seller of consumer telecommunications in the world. But times change. The internet came along, the company declined, and in 2015 it filed for Chapter 11 bankruptcy. Aside from a few stalwart independently owned stores, the brand disappeared in the U.S. The company was sold, bounced around with various owners and their revitalization plans, and generally went nowhere. Few noticed that an outfit called Unicomer Group, based in El Salvador, had bought the brand’s exclusive use in Central and South America, and the Caribbean. Price? $5 million.

Unicomer had been a franchisee of RadioShack since 1998 and by 2015 it had expanded to 57 physical stores in four countries. After its purchase from the bankruptcy court, things got even better. They added company-owned stores and picked up existing franchises in other countries. In fact, under its new management, RadioShack is doing pretty well.

Now here’s the really interesting part: In May of this year, Unicomer acquired the RadioShack brand in about 70 more countries – including the U.S., Canada, Europe and China. With a 25-year proven track record of successful retail management, could Unicomer bring RadioShack back to its brick-and-mortar global glory? [Continue reading…]

Future Salvaging Missions to the Titanic Are at Risk After the U.S. Government Blocked the Recovery of a Historic Artifact From the Wreck (Art Net)

The federal government has filed a motion to block a proposed mission to salvage the ship’s wireless telegraph.

The wreck of the Titanic has been a source of ongoing fascination since it was first discovered in 1985. As it continues to decompose, there has been a race against time to capture and preserve the ship and its contents, whether through high-tech scans or by salvaging artifacts.

Many fascinating items have been successfully recovered, including one passenger’s alligator purse, jewelry, vials of perfume, a bowler hat, sheet music, and a logometer. Their retrieval has been controversial because the wreck is not only a site of historical significance but also the resting place of over 1,500 passengers that sunk with the ship on April 15, 1912.

Now, the U.S. government is aiming to block a proposed mission to rescue the Marconi wireless telegraph. This important machine was used to transmit a distress call when the ship was sinking and helped save the 700 people who made it onto lifeboats. It has been located on the wreck and will eventually disintegrate if not salvaged, but its removal risks damaging the boat’s hull.

The recovery would be carried out by RMS. Titanic, Inc., a company based in Atlanta, Georgia that was handed exclusive salvaging rights to the wreck by a federal court in Norfolk, Virginia in 1994. Prior to this, U.S. Congress had discouraged disturbing or salvaging the wreck, but no formal, legally-enforced agreement had materialized. [Continue reading…]

Czech National Bank issues special coin to commemorate 100 years of Czech Radio (Czech Radio)

A special CZK 200 silver coin has been issued by the Czech National Bank to mark the 100th anniversary of Czech Radio. The coin’s design features images related to the history of the radio’s first broadcasts.

It was way back in 1923, specifically on May 18 at 8:15pm in the evening, that Czechoslovak Radio began broadcasting from what was a Scouts’ tent in Prague’s Kbely district. Czechoslovakia thus became only the second country in Europe to establish regular broadcasting. At first these were only hour-long broadcasts, but soon they grew into longer and more varied segments that even included broadcasting in English and Esperanto as early as 1924.

The popularity, size and resources of the country’s radio grew rapidly from that point onwards and Czechoslovak Radio would go on to also play important roles in the country’s history by providing vital information to its citizens during the 1945 uprising against Nazi occupation forces and the 1968 Invasion of Czechoslovakia.

No wonder then that the centenary the country’s public broadcaster is being celebrated in great style. Czech Radio itself has prepared a variety of events and shows commemorating the anniversary this year – and especially this week. Meanwhile, the Czech Post has issued special stamps marking the occasion.

Now, the Czech National Bank has joined in, by issuing its own special CZK 200 silver coin. On one side, it features pictures of a radio microphone, transmission masts and of the historic broadcasting facility in Kbely. The other side of the coin shows the tent from which the first broadcast was made and the logo of Czechoslovak Radio. The design is the work of academic sculptor Marie Šeborová, who has already created several commemorative coins and medals in the past. Continue reading →

Radio Waves: SpaceX Encrypts Falcon 9 After Ham Downloads Data, Postcard From Titanic Op at Auction, History of Sound Art, and WNYC’s Early Recording

Radio Waves: Stories Making Waves in the World of Radio

SpaceX Encrypts Falcon 9 Telemetry After Amateur Radio Operators Download Data (Extreme Tech)

SpaceX doesn’t operate like a traditional aerospace company. For one, the CEO is usually hamming it up on Twitter during launches and providing details that would usually go in a press release. SpaceX also live streams almost all of its launches, even the prototypes that have an unfortunate tendency to blow up lately. It wasn’t even encrypting the Falcon 9 telemetry feed… until now. Unfortunately, some digging by amateur radio tinkerers seems to have convinced SpaceX to step up its security.

It all started a few weeks ago when several Redditors managed to lock onto the 2232.5 MHz telemetry downlink from a Falcon 9 upper stage. Right away, they were able to pull out a few interesting plaintext snippets from the unencrypted feed. With a little more work, the radio enthusiasts were able to capture some amazing images from the spacecraft’s cameras.

After that discovery was public, other SpaceX fans tried to grab some data from the Starship during its prototype tests. However, SpaceX had chosen to encrypt that data. Even with the right wireless equipment, the decoded signal was just noise. Now, it appears the same thing is happening with the Falcon 9. When attempting to pull data from the most recent Falcon 9 launch, the original signal snoopers discovered it had also been encrypted. A series of tweets from SpaceX engineers suggest the decoding of the telemetry signal was the reason for the change.[…]

Postcard from Titanic’s radio operator is being sold at auction (Stars And Stripes)

BOSTON — A postcard written by the Titanic’s senior radio operator just weeks before the ocean liner sank in the North Atlantic in 1912 has been put up for auction.

The card, with a glossy image of the ill-fated ship on the front, was written by Jack Phillips to his sister, Elsie Phillips, in March 1912 while awaiting the ship’s first sea trials, according to RR Auction in Boston.

“Very busy working late. Hope to leave on Monday & arrive Soton Wednesday afternoon. Hope you quite OK. Heard from Ethel yesterday,” he wrote. It’s signed “Love Jack.”

It is postmarked Belfast, where the Titanic was built, and has a canceled halfpenny stamp.

“Soton” is a contraction of Southampton, the English port city from where the Titanic departed on its maiden voyage. It sank in the early morning hours of April 15.

Phillips, who turned 25 on board, stayed at his post after the Titanic struck an iceberg to send calls for assistance to other ships in the area until water was lapping around his feet, according to RR Auction.

He made it off the ship after being told by the captain that he had done his duty, according to his biography in the British National Archives, but died of exposure in the frigid North Atlantic, according to RR Auction.

The postcard is being sold by the estate of Vera and John Gillespie, longtime members of the Massachusetts-based Titanic Historical Society, said Bobby Livingston, executive vice president at RR Auction.[…]

Radio Survivor Podcast #292: The History of Sound Art (Radio Survivor)

What is sound art? And what do we know about its origin story? We explore this question and more with our guest this week, artist and educator Judy Dunaway. An adjunct professor in the History of Art Department at Massachusetts College of Art and Design, Dunaway’s recent article, “The Forgotten 1979 MoMA Sound Art Exhibition,” is a fascinating look at the history of sound art and highlights important contributions by female artists. In our wide-ranging discussion, we also hear about Dunaway’s own artistic practice, from her work with latex balloons to transmission art to a “phone improv” show over BlogTalkRadio a decade ago.

Overcoming the Limitations of Time (From the January/February 1940 WNYC Masterwork Bulletin)

A MATTER OF RECORD: Mighty useful gadgets are WNYC’s four new recording machines. They were used in a variety of interesting ways during the past year, so we decided that the how and the why of recording would be an appropriate subject for this, the third of our Behind the Microphone series dealing with the technical side of things at the Municipal Station.

One of the most valuable uses of the recording units is that they have partially enabled us to overcome the limitations of time — have made it possible to make available to our listeners important evening programs which we could not broadcast directly because of our fluctuating time allotment.

For instance, we could not pick up the ASCAP Music Festival Concerts from Carnegie Hall last Fall because WNYC was not on the air after 8:30 P. M.[1] What to do? The recorders to the rescue! The concerts were “broadcast” over our regular Carnegie Hall lines to the Municipal Building where they were transcribed on our two standard studio-type recording machines. Each transcription[2] was put on the air on the afternoon following the original perfor

Similarly, our two mobile recording units made possible an afternoon broadcast of the official opening of La Guardia Field which took place at midnight. Recording equipment is also used frequently to transcribe major programs “off the air” so that they may reach a larger audience through rebroadcast. There was the time, for example, when the Mayor’s office was the scene of a final report on the new Police and Fireman’s pension plan. Official reports on the balloting were recorded and rebroadcast at a time when the majority of the policemen and firemen affected could listen in.

We used to think recording an easy job: Just put the recording needle on the disk, turn a few buttons, and let ‘er go. After watching one of our expert recording engineers at work, we realized that it’s a delicate task, requiring special training and long practice.

Rebroadcasts of RFI programs halt over alleged “pro-China” stance (RTI)

Taiwan’s National Education Radio has decided to stop domestic rebroadcasts of Radio France Internationale’s programs. That’s after receiving listener complaints that the station’s news programs repeated Chinese talking points that praised Beijing, belittled Taiwan, and criticized the US.

National Education Radio had rebroadcast Radio France Internationale’s French and Chinese programs for Taiwanese audiences during two daily time slots under an agreement arranged by RTI.

During a meeting of the Legislature’s culture and education committee Wednesday, KMT lawmakers said that the education ministry should investigate whether the listener complaints were justified or not. They also expressed concern about what pulling the plug of the rebroadcasts might mean for freedom of speech and the press in Taiwan.

During the meeting, Education Minister Pan Wen-chung said that the rebroadcasting agreement had been intended to foster exchanges with France. Pan said the programs originally rebroadcast were mainly focused on educational and cultural topics. However, Pan said that RTI and National Education Radio have decided to temporarily stop the rebroadcasts, since the content of the re-broadcasted programs had begun to deviate from these non-political topics.

Pan said that he had not personally listened to the rebroadcast programs. He also said that the education ministry had not been informed about the decision to halt rebroadcasts until RTI and National Education Radio had already decided to do so among themselves. However, he said that the education ministry supports the decision.[…]

US court grants permission to recover Marconi telegraph from Titanic wreckage (ARS Technica)

But NOAA is fiercely opposed to the controversial salvage mission.

When RMS Titanic struck an iceberg on April 14, 1912, crew members sent out numerous distress signals to any other ships in the vicinity using what was then a relatively new technology: a Marconi wireless telegraph system. More than 1,500 passengers and crew perished when the ship sank a few hours later. Now, in what is likely to be a controversial decision, a federal judge has approved a salvage operation to retrieve the telegraph from the deteriorating wreckage, The Boston Globe has reported.

Lawyers for the company RMS Titanic Inc.—which owns more than 5,000 artifacts salvaged from the wreck—filed a request in US District Court in Alexandria, Virginia, arguing that the wireless telegraph should be salvaged because the ship’s remains are likely to collapse sometime in the next several years, rendering “the world’s most famous radio” inaccessible. US District Judge Rebecca Beach Smith concurred in her ruling, noting that salvaging the telegraph “will contribute to the legacy left by the indelible loss of the Titanic, those who survived, and those who gave their lives in the sinking.”

However, the National Oceanic and Atmospheric Administration (NOAA) is fiercely opposed to the salvage mission. The agency argues in court documents that the telegraph should be left undisturbed, since it is likely to be surrounded “by the mortal remains of more than 1500 people.” Judge Smith countered in her decision that the proposed expedition meets international requirements: for instance, it is justified on scientific and cultural grounds and has taken into account any potential damage to the wreck.[…]

Why Titanic’s first call for help wasn’t an SOS signal (National Geographic)

When RMS Titanic set sail in 1912, it was blessed and cursed with the latest in communication technology—the wireless telegraph. In the last hours after Titanic hit an iceberg, radio messages sent from the storied sinking ship summoned a rescue vessel that saved hundreds of people, but also sowed confusion with competing distress calls and signal interference. More than 1,500 people died that fateful night.

Now, a recent court ruling may pave the way to the recovery of Titanic’s telegraph, designed by Guglielmo Marconi, a telecommunications pioneer and 1909 Nobel Prize winner in physics who invented the first device to facilitate wireless communications using radio waves.

[…]Despite the limitations of the Marconi telegraph—and the fact that it wasn’t intended to be used as an emergency device—Titanic was outfitted with a radio room and a Marconi-leased telegraph machine. Two young Marconi-employed operators, chief telegraphist Jack Phillips and his assistant Harold Bride, sent Morse code “Marconigrams” on behalf of Titanic’s well-heeled customers 24 hours a day during its maiden voyage in April 1912.

Both Marconi’s technology monopoly and the torrent of personal messages conveyed through Titanic’s telegraph proved fatal on that April night. Phillips was so overwhelmed by a queue of incoming and outgoing guest telegrams —one Titanic passenger wanted to “notify all interested” about an upcoming poker game in Los Angeles—that he didn’t pass on messages about the ice threatening Titanic’s ocean environs. When a nearby vessel, SS Californian, telegraphed that it was already surrounded by ice, Phillips testily responded “Shut up! I am busy.”

Once Titanic hit the iceberg, Phillips tone shifted and he used the Marconi distress signal: “CQD.”[…]

Temporary Rule Waivers Announced for 2020 ARRL Field Day (ARRL News)

With one month to go before 2020 ARRL Field Day, June 27 – 28, the ARRL Programs and Services Committee (PSC) has adopted two temporary rule waivers for the event:

1) For Field Day 2020 only, Class D stations may work all other Field Day stations, including other Class D stations, for points.

Field Day rule 4.6 defines Class D stations as “Home stations,” including stations operating from permanent or licensed station locations using commercial power. Class D stations ordinarily may only count contacts made with Class A, B, C, E, and F Field Day stations, but the temporary rule waiver for 2020 allows Class D stations to count contacts with other Class D stations for QSO credit.

2) In addition, for 2020 only, an aggregate club score will be published, which will be the sum of all individual entries indicating a specific club (similar to the aggregate score totals used in ARRL affiliated club competitions).

Ordinarily, club names are only published in the results for Class A and Class F entries, but the temporary rule waiver for 2020 allows participants from any Class to optionally include a single club name with their submitted results following Field Day.

For example, if Podunk Hollow Radio Club members Becky, W1BXY, and Hiram, W1AW, both participate in 2020 Field Day — Hiram from his Class D home station, and Becky from her Class C mobile station — both can include the radio club’s name when reporting their individual results. The published results listing will include individual scores for Hiram and Becky, plus a combined score for all entries identified as Podunk Hollow Radio Club.

The temporary rule waivers were adopted by the PSC on May 27, 2020.

ARRL Field Day is one of the biggest events on the amateur radio calendar, with over 36,000 participants in 2019, including entries from 3,113 radio clubs and emergency operations centers. In most years, Field Day is also the largest annual demonstration of ham radio, because many radio clubs organize their participation in public places such as parks and schools.

Due to the COVID-19 pandemic, many radio clubs have made decisions to cancel their group participation in ARRL Field Day this year due to public health recommendations and/or requirements, or to significantly modify their participation for safe social distancing practices. The temporary rule waivers allow greater flexibility in recognizing the value of individual and club participation regardless of entry class.

ARRL is contacting logging program developers about the temporary rule waivers so developers can release updated versions of their software prior to Field Day weekend. Participants are reminded that the preferred method of submitting entries after Field Day is via the web applet. The ARRL Field Day rules include instructions for submitting entries after the event. Entries must be submitted or postmarked by Tuesday, July 28, 2020.

The ARRL Field Day web page includes a series of articles with ideas and advice for adapting participation this year.[…]

Radio Waves: ABC Wage Freeze, A Titanic Radio, FCC “Tweaks” LPFM Rules, and Digitizing a DX-160 Display

Radio Waves: Stories Making Waves in the World of Radio

Many thanks to SWLing Post contributors Michael Bird, Dave Zantow, David Korchin, and Alokesh Gupta for the following tips:

ABC must freeze wages, government warns (The Guardian)

The Morrison government has put the national broadcaster on notice that it expects the ABC to embark on a six-month wage freeze to bring it in line with other taxpayer-funded agencies during the Covid-19 crisis.

The warning follows the government’s decision in early April to defer general wage increases for commonwealth public servants for six months. The public service commissioner followed up that directive by writing to all non-public service agencies – including the ABC – informing them the government expected them to adopt the same practice.

With no clear response from the ABC to the 9 April missive, Guardian Australia understands the communications minister Paul Fletcher wrote to the national broadcaster this week flagging his expectation that the organisation would defer a 2% increase for all employees scheduled to take effect in October under the ABC’s enterprise agreement.[…]

Radio used by the Titanic to call for help can be salvaged, judge rules (CNN)

A federal judge has ruled that RMS Titanic Inc. can salvage the radio used to call for help by the fated ocean liner after it struck an iceberg in 1912.

To get to the radio, divers would need to remove a part of the ship’s deckhand to reach the room known as the Marconi Suite, which houses the device.

The ruling modified an order issued on July 28, 2000, that said that RMS Titanic Inc. could not cut into the wreckage or detach any part of it.

Virginia’s eastern district court amended that order “for a unique opportunity to recover an artifact that will contribute to the legacy left by the indelible loss of the Titanic, those who survived and those who gave their lives in the sinking,” Judge Rebecca Beach Smith wrote.

Experts in the case testified to the “significant deterioration” in areas above and around the Marconi room, according to the document, and photos showed the “increasing breakdown” in the deck above the suite.

The suite, made of steel, consisted of three areas: sleeping accommodations, an operator’s room and the silent room that housed the radio. Each area was separated by wood walls that officials believe have dissolved, according to court documents.

The Marconi device and the artifacts associated with it face “significant threat of permanent loss,” the judge said in her approval of the expedition.[…]

FCC Tweaks LPFM Technical Rules (Radio World)

The FCC in April modified the technical rules covering low-power FM stations. It expanded the permissible use of directional antennas; permitted waivers of protections of television Channel 6 by a specific group of reserved channel stations; expanded the definition of minor change applications for LPFM stations; and allowed LPFM stations to own boosters. Read more about the changes here.

Michelle Bradley, founder of REC Networks, is an engineer and longtime LPFM advocate.

Radio World: What’s your overall assessment of the outcome and the scope of its impact in the LPFM community?

Michelle Bradley: While the FCC did not address three major issues that are impacting LPFM stations right now —the ability to address building penetration issues, the ability to reach “local” listeners in rural areas and the disparity in how LPFM stations protect FM translators vs. how translators protect LPFMs — the changes will benefit current LPFM stations by giving them more flexibility in moving locations, reduce the need for waivers and improve LPFM service in the southern border region. It will also open some additional opportunities for new LPFM stations in the next filing window.[…]

RadioShack Shortwave Goes Digital (Hackaday)

If you spent the 1970s obsessively browsing through the Radio Shack catalog, you probably remember the DX-160 shortwave receiver. You might have even had one. The radio looked suspiciously like the less expensive Eico of the same era, but it had that amazing-looking bandspread dial, instead of the Eico’s uncalibrated single turn knob number 1 to 10. Finding an exact frequency was an artful process of using both knobs, but [Frank] decided to refit his with a digital frequency display.

Even if you don’t have a DX-160, the techniques [Frank] uses are pretty applicable to old receivers like this. In this case, the radio is a single conversion superhet with a variable frequency oscillator (VFO), so you need only read that frequency and then add or subtract the IF before display. If you can find a place to tap the VFO without perturbing it too much, you should be able to pull the same stunt.

In this receiver’s heyday, this would have been a formidable project. Today, a cheap digital display will do fine.[…]

Titanic radio may soon be recovered

Replica of the Titanic’s radio room at the Antique Wireless Museum (Source: Trip Advisor)

(Source: The Washington Post via Davud Iurescia, LW4DAF)

[…]“Lying two and a half miles below the ocean surface, the RMS Titanic is the subject of the most documented maritime tragedy in history,” British Transport and Maritime Minister Nusrat Ghani said in a statement. “This momentous agreement with the United States to preserve the wreck means it will be treated with the sensitivity and respect owed to the final resting place of more than 1,500 lives.”

A century later and the Titanic still fascinates

RMS Titanic Inc. argues that the wireless transmitter must be recovered soon, and ideally within the year, as expeditions to the site more than two miles below the ocean’s surface have noted deterioration over the years. The “Silent Cabin,” the soundproof room where it is housed, withstood years of damage and protected the transmitting switchboards and regulators, the company wrote in court documents.

But the deckhouse above the Marconi transmitter has been falling apart since 2005, and holes have been forming over the Silent Cabin. The overheard will probably collapse within the next few years, Titanic expert Parks Stephenson wrote in court documents, “potentially burying forever the remains of the world’s most famous radio.”

[…]RMS Titanic Inc. President Bretton Hunchak, however, has said the radio recovery mission would be limited in scope and undertaken in an effort to protect the important artifact before it’s too late.

“It’s not some kind of Trojan horse so that we can start grabbing suitcases full of diamonds from the wreck,” he said, according to the Telegraph. “This is a careful, surgical operation to rescue a historically significant item so it can teach future generations about the story of Titanic.”[…]
