Ham radio operators honor legacy of Mars Hill company (Citizen Times)

During the 1950’s and ’60’s, when the Hammarlund Manufacturing Company had a factory just west of Mars Hill College, the town could have been considered a world center of advanced electronic technology. With a company motto of “Quality Without Compromise,” almost 90% of American WWII wartime military electronic equipment employed Hammarlund capacitors. They also built U.S. Navy search radar installed on aircraft carriers, battleships and cruisers.

Hammarlund was one of the three leading brands of radio communications equipment at the time, along with Hallicrafters and Collins Radio. These three companies dominated in providing state of the art electronics equipment to the U.S. military, large and small corporations, and to private individuals who had the means and taste to own the very best.

Hammarlund Radio initially operated out of New York City starting in 1910, in the early days of radio. They began consolidating all of their operations in Mars Hill in 1951, in a newly constructed facility that spread out to over 100,000 square foot on Hammarlund Drive — now named Hickory Drive. The site employed hundreds from around the area and their work lives on today. []

FM Radio From Scratch Using An Arduino (Hackaday)

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive. That’s good enough for AM radio, anyway, but you’ll need to try this DIY FM receiver if you want to listen to something more culturally relevant.

Receiving frequency-modulated radio waves is typically more difficult than their amplitude-modulated cousins because the circuitry necessary to demodulate an FM signal needs a frequency-to-voltage conversion that isn’t necessary with AM. For this build, [hesam.moshiri] uses a TEA5767 FM chip because of its ability to communicate over I2C. He also integrated a 3W amplifier into this build, and everything is controlled by an Arduino including a small LCD screen which displays the current tuned frequency. With the addition of a small 5V power supply, it’s a tidy and compact build as well.[]

2016 Report Confirmed Problem of Political Bias At Voice of America (USAGM Watch)

by Dan Robinson

Trump USAGM CEO Michael Pack Was Attacked For Attempts to Focus on Problem

It was May of 2016 and Amanda Bennett was only a few weeks into what would become a nearly four year stint as director of the Voice of America, among the “plum” jobs in Washington, D.C.

Bennett was just getting her feet wet, and at the time was dependent on a group of longtime embedded VOA managers that she would at one point describe as a “fantastic leadership team.”

She had received fair warning, from former VOA employees and extensive reporting by the independent watchdog website BBG and USAGM Watch, of disturbing issues at VOA, located in what has long been one of the most dysfunctional of federal agencies.

Some VOA journalists were using their taxpayer-funded positions to engage in self-promotion and campaign for political causes, a fact little known to most Americans. VOA’s website and digital operations were plagued by failures in breaking news coverage, and inaccuracies in content.

Both VOA and what was then called the Broadcasting Board of Governors (BBG) were increasingly seen by U.S. lawmakers as moribund. A Republican-led and eventually bipartisan effort in Congress proposed major restructuring – there was little patience left on Capitol Hill where the agency was increasingly considered to be “broken,” “rudderless,” and “worthless.” President Obama signed the reform legislation in December 2016 to create a powerful agency CEO position and to make the BBG Board purely advisory.[]

ARISS Slow Scan TV event (Southgate ARC)

An ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS) for late December. This will be a special SSTV event to celebrate the 20th anniversary of ARISS.

The event is scheduled to begin on December 24 and continue through December 31.

Dates are subject to change due to ISS operational adjustments.

The Geminids – a reminder (Southgate ARC)

The Geminids are a prolific meteor shower caused by the object 3200 Phaethon, which is thought to be a Palladian asteroid with a “rock comet” orbit. This would make the Geminids, together with the Quadrantids, the only major meteor showers not originating from a comet.

They are the biggest meteor shower of the year, and normally occur between 4 December – 17 December.

The peak is expected on 14 December.

Expect FM “pings” and hopefully interesting dx opportunities.

The voice of Phil Irwin will be greatly missed (Rappahannock News)

Where wasn’t the presence of Phil Irwin felt in Rappahannock County?

A constant of virtually all proceedings of the Rappahannock County community and government, cherished innkeeper of Caledonia Farm – 1812, founding member of the Rappahannock League for Environmental Protection, regional director of the Virginia Farm Bureau, committee member for both Rappahannock County Farmland Preservation and the Agricultural Forestal District, Rappahannock tourism advisory member — for 25 years chief of morning broadcasts for Voice of America (VOA) — Irwin was found dead Thursday at his working cattle farm north of Washington.

“What a contribution Phil made to our county over his many years here,” Huntly friend Ralph Bates reacted upon learning of Irwin’s death. “He will live in our memories as we drive and see how well our viewshed and environment has been protected because of his commitment and work.”

Former Washington Mayor John Fox Sullivan recalled “a good man and such a part of the Rappahannock fabric. His love for this county, and commitment to it, was unmatched.”[]

Federal watchdog finds ‘substantial likelihood of wrongdoing’ by Trump appointees overseeing Voice of America (NBC News)

The federal watchdog’s findings mark the latest rebuke of the Trump-appointed CEO of the U.S. Agency for Global Media, Michael Pack.

WASHINGTON — A federal watchdog agency has found “a substantial likelihood of wrongdoing” by Trump administration appointees who oversee the Voice of America and other U.S.-funded media outlets.

The finding from the U.S. Office of Special Counsel, an independent government agency charged with safeguarding federal employees’ rights, marks the latest rebuke of Michael Pack, who President Donald Trump appointed to run the U.S. Agency for Global Media, the parent agency to VOA and other broadcasters.

A federal judge last month ordered Pack to stop interfering in the newsrooms of VOA and other media outlets and found that he had jeopardized the First Amendment rights of journalists that his office had targeted for investigation. Lawmakers from both sides of the aisle and press freedom groups have blasted Pack over his actions since he took over in June, accusing him of undermining the broadcasters’ editorial independence and defying congressional authority.

After reviewing allegations from current and recent employees, the Office of Special Counsel wrote to the whistleblowers Wednesday saying it had demanded Pack and the U.S. Agency for Global Media conduct an investigation into the allegations.[]

The December 2020 Eclipse Festival of Frequency Measurement (HamSCI)

Changes in ionospheric electron density caused by space weather and diurnal solar changes are known to cause Doppler shifts on HF ray paths. For example, see Figure 7 in Boitman et al., 1999. HamSCI’s first attempt at a measurement of these Doppler shifts was during the August 2017 total solar eclipse. We plan a careful measurement during the 2024 eclipse. As part of the WWV centennial, 50 stations collected Doppler shift data for the original Festival of Frequency Measurement, demonstrating the value of volunteer participation in collecting this data. During the June 2020 Eclipse Festival, we enlisted participants around the globe and experimented with different data collection protocols. This winter, we request that all amateur radio stations, shortwave listeners, and others capable of making high-quality HF frequency measurements help us collect frequency data for the December 14 total eclipse.[]

USAGM, VOA Testing Innovative Digital Radio Platform (Inside VOA)

A few weeks before the COVID-19 pandemic shut down much of the world, broadcast engineers in Greenville, North Carolina, launched a test of digital radio signals. The U.S. Agency for Global Media began aiming a digital broadcast at Cuba and Latin America, which included Office of Cuba Broadcasting and Voice of America content.

With this 2020 test, VOA embarked on a new phase of global innovation on a platform called Digital Radio Mondiale (DRM), a versatile digital signal not well known in the U.S., but the only one that can cover the entire spectrum: shortwave, mediumwave and longwave, as well as VHF (FM). As digital radio emerged in the 1990s, VOA was among the first broadcasters testing a signal that promised to even out shortwave radio signals that often faded in and out and were marred by static.

VOA tested the DRM signal in the 1990s at the agency’s Morocco transmitter site, one of five facilities opened in a period of expansion in the previous decade. However, other digital signals became the standard in various markets around the world. The U.S. standard audio digital platform is called HD.

Around the world, as other digital radio platforms were adopted, DRM was held back by the marketplace. Nobody was making commercially available receivers.

By the end of the 1990s, VOA innovation focused more on television, the platform that promised larger audiences, even in some places in the world where shortwave dominated. By the early 2010s, the rallying cry became “Digital First,” as VOA strived to attract readers for its language service websites and began tapping into the growing audiences on new social media sites like Facebook, Twitter, Instagram and YouTube.

By 2020, however, DRM had come full circle.

“You’re no longer limited to just reading the news or playing music,” says Gerhard Straub, supervisory director of the USAGM Broadcast Technologies Division.

Straub, along with Gary Koster, Broadcast Radio Technician and transmitter expert and Macon Dail, Chief Engineer at the Greenville Transmitting Station, set up the test broadcast in February of this year, not long before the COVID-19 pandemic grounded global travel. The trio put up a DRM signal with Radio Marti and VOA audio along with scrolling text messages and rotating images.

Engineers have received reports of a clear signal as far south as Brazil.

The USAGM test, says Straub, is “coasting along” in the pandemic, but additional content will be added when technicians can travel again. Straub says the VOA signal was taken off in the initial test to concentrate on the OCB digital content and to keep the signal robust. Now that there is good reception data, he noted, the digital bit rate can be increased and VOA content added back into the test in 2021.

Because DRM operates at lower power, more radio stations and digital signals can be broadcast on a single transmitter. The platform is starting to grow in countries of interest to Western international broadcasters. DRM signals will soon cover all of China, though its government is expected to attempt to control the stations accessed by its citizens. India built 39 transmitters and, more importantly, 2.5 million vehicles already are equipped with DRM radios. Indonesia, Pakistan, Brazil and North Korea all have nascent DRM operations.

Religious broadcasters, who sometimes target audiences similar to those sought by Western governments, are experimenting with the technology. For example, a missionary group, TWR.org, sent the Bible’s Gospel of Mark from Guam to Cambodia via DRM shortwave.

“You have to stop thinking of it as radio, because it’s not,” says USAGM’s Straub. “We are now broadcasting digital data. Just like we broadcast digital data on the internet, we can broadcast digital data over shortwave without being hampered by an internet firewall that maybe limits what we can send to a particular country.”

Reason enough, Straub believes, for VOA to continue leading innovation in a new-again technology.[]

Meet the guardians of the world’s earliest musical recordings (LA Times)

The voice seeps in as if from another dimension, hissy and distant, like an AM radio broadcaster transmitting through late-night static.

“‘The Ambassador March’ by Brown’s Orche-streee for the Los Angeles Phonograph Company of Los Angeles, California,” a man announces with a gentlemanly accent. After a moment’s scratchy pause, a violinist opens with a melody, and a small orchestra jumps in. Led by a Long Beach-based bandleader named E.R. Brown, the song dances along for two minutes.

The fidelity is primitive by today’s high-definition audio standards, a quaint toss-away. But “The Ambassador March” and the Coke-can-sized wax cylinder upon which it was etched into permanence in the late 1800s open a portal to another era.

That wax cylinder and others like it — rescued from rural estate sales and dusty attics — have survived earthquakes, heat waves, mold and indifference. They feature Mexican folk songs; military band marches; minstrelsy songs of the kind that preceded American blues, folk and country music; and the voices of former Lincoln cabinet members, Southern senators, popes, preachers and comedians. Their survival is emblematic of a revolution that allowed sound to be freed from its origins. Once untethered, the world would be forever changed.[]

US international broadcasting: Rebuilding the firewall in the new administration (The Hill)

by Kim Andrew Elliott

President-elect Joe Biden, who as a senator had a key interest in U.S. international broadcasting, is looking at its future.

He named Richard Stengel, former undersecretary of state for public diplomacy, to head the transition team for the U.S. Agency for Global Media (USAGM). Under USAGM are the Voice of America, Radio Free Europe/Radio Liberty Inc., Radio Free Asia Inc., Office of Cuba Broadcast (Radio/TV Martí to Cuba) and Middle East Broadcasting Networks Inc. (the Arabic-language Alhurra TV and Radio Sawa).

With government officials under President Trump instructed not to cooperate with Biden’s teams, the transition for the time being will have to be done from afar. The Trump-appointed USAGM CEO Michael Pack, whose leadership has fomented several controversies since he was installed in June, might decide to be a benign, if uncooperative, caretaker until the new management comes in. Or he could impose personnel changes and alterations in content that could diminish the credibility of the USAGM entities, a situation that could take years to repair.

During his campaign, Biden promised to fire Pack. Pack might try to serve out the three-year term stipulated in the legislation that replaced the bipartisan Broadcasting Board of Governors (BBG) with a politically appointed CEO (Pack being the first). If such an attempt ends up in court, a June Supreme Court decision overruling the fixed term of the director of the Consumer Finance Protection Bureau, a victory for the Trump administration, could, ironically, be the undoing of any plans by Pack to stay on at USAGM.

Pack has already left his mark by rescinding the firewall “rule” published in June by the outgoing BBG. The rule, however, was not an act of Congress or a presidential directive. It was simply language placed in the Federal Register “to codify and memorialize definitions and practices associated with the firewall.” On such shallow roots, this tree was easy to fall. In October, Pack issued a repeal, which waved away the firewall rule as readily as it was instituted.[]

A New HF Station that’s Similar, but Different (DRMNA.info)

On October 21, 2020, DPA Mac LLC filed a FCC license application for a new, DRM-based International Broadcast Station to be located in Maple Park, IL. The principal is San Francisco entrepreneur Seth Kenvin and its technical consultant is Tamir Ostfeld of Raft Technologies, an Israeli developer of low-latency HF systems for so-called algorithmic trading.

No station devoted to algorithmic trading has ever been authorized for regular commercial operation in the U.S., as there is no formal radio service or spectrum allocation for that purpose. Several such stations have been licensed in the Experimental Radio Service (ERS), which is ostensibly for scientific studies only.

If the FCC licenses DPA Mac, it will be the first such station to make the transition from the ERS to regular, non-experimental licensing. This station would be the successor to experimental station WI2XXG. Other than the license document, the FCC has withheld most of WI2XXG’s records from public disclosure since it was first licensed in 2017.

DPA Mac is similar to other DRM stations on which we previously reported: WIPE in Alpine, NJ, which is built and is waiting on its FCC license; and WPBC, proposed for Batavia, IL. With regard to their use for non-broadcast, private data transmissions, those stations made general and non-descriptive representations to the FCC. On the other hand, DPA Mac’s license application is fairly transparent. The station aims to transmit “investment data from points within the United States to locations outside the United States carried over a channel immediately adjacent to the HF broadcasts…a low-power, low-latency digital data transmission service provided to private investors, including small- and medium-sized firms.” [Continue reading…]

Sudbury sculptor’s latest work honours Fern Blodgett Sunde (CBC)

‘The wave she touches symbolizes the wave of social change that came for Canadian women in the storm of war’

A sculptor from Sudbury has unveiled his latest life-sized bronze statue in honour of the first woman to work as a wireless radio operator.

Canadian Fern Blodgett Sunde served on a Norwegian merchant ship, during WW II’s Battle of the Atlantic.

Tyler Fauvelle’s statue of Sunde also honours all Canadians who served during that time — and it was unveiled in Cobourg earlier this month, where Sunde grew up. Fauvelle’s work includes more than a dozen public art bronze monuments, four of which are military-themed.

“Fern’s clothing is very typical of what she wore as she carried out her duties as a wireless operator aboard the Mosdale,” Fauvelle said.

“The headphones slung around her neck symbolize her work and her profession. The pin on her lapel commemorate the sisterhood of Sparks who followed her to sea. The wave she touches symbolizes the wave of social change that came for Canadian women in the storm of war.”

In 1943, she was awarded the Norwegian War Medal, the first woman ever to receive the honour.

“It was a privilege to create this lasting tribute to Canadians of a monumental generation, the men and women who fought and supported a necessary war,” Fauvelle said.

“Thousands didn’t live to see the peace that their sacrifice bought, and they were on my mind as I sculpted the clay.”[]

U.S. Agency Targets Its Own Journalists’ Independence (NPR)

A regulatory “firewall” intended to protect Voice of America and its affiliated newsrooms from political interference in their journalism was swept aside late Monday night by the chief executive of the federal agency which oversees the government’s international broadcasters.

Michael Pack, a Trump appointee who assumed leadership of the U.S. Agency for Global Media in June, wrote that he acted to eliminate policies that were “harmful to the agency and the U.S. national interest.” And Pack argued they had interfered with his mandate “to support the foreign policy of the United States.”

Pack has already come under fire for revelations that his senior aides investigated the agency’s journalists for bias against President Trump and pushed for their dismissals and reassignments, in seeming violation of the rules he has now rescinded, effective immediately.

“The key to the credibility of any news organization is editorial independence and adherence to the professional standards of journalism,” said David Kligerman, whom Pack suspended as the agency’s general counsel in August.

Kligerman was the chief author of the regulation which Pack just killed. It was supported by the agency’s bipartisan board, which was dissolved upon Pack’s confirmation. Kligerman is also among a group of a half-dozen whistleblowers who have come forward to challenge Pack’s actions since he arrived in June.

“The firewall protects the networks by insulating their editorial decisions from political interference,” Kligerman said. “That is what differentiates the Voice of America and the other USAGM-funded networks from the state-sponsored propaganda of Russia, China, Iran and others.”[]

KDKA Centennial-The birth of Commercial Radio (Southgate ARC)

November 2, 2020 marks the centennial of radio station KDKA going on the air for the first time. Their first broadcast, considered by many to be the birth of commercial broadcast radio, was to report the election results of the Harding-Cox presidential race. KDKA has been on the air continuously ever since.

To celebrate this historic milestone, Pittsburgh area amateur radio operators, also known as hams, will take to the airwaves with a series of special event stations. Their goal is to contact as many other ham radio operators across the United States and around the world. They will be celebrating the centennial of KDKA for the entire month of November.

KDKA originally began operations in 1916 as an amateur radio station, call sign 8XK, operated by Dr. Frank Conrad, Assistant Chief Engineer of Westinghouse Electric and Manufacturing Company. During World War I, amateur radio operations were ordered to be suspended because of national security concerns. After the war, the operators reorganized the station as a commercial AM radio station. The first transmissions of KDKA were from a makeshift studio on a roof of the Westinghouse K Building in East Pittsburgh.

Ham radio clubs participating in the centennial special event include the North Hills Amateur Radio Club in Pittsburgh, which is planning to operate from II-VI Incorporated located in Saxonburg, Pennsylvania, the former KDKA transmitter site from 1931 to 1939. One of the original tower piers still stands on the property to this day. Another operating location is being planned at the Westinghouse Lodge in Forest Hills, located about ten miles east in suburban Pittsburgh, which was the former KDKA transmitter site from 1923 to 1930.

Other Pittsburgh area ham radio clubs planning operations include the Panther Amateur Radio Club in addition to a joint operation planned between the Steel City Amateur Radio Club and the Wireless Association of South Hills. Outside of Pittsburgh, other ham radio clubs planning operations are The Skyview Radio Society in New Kensington, Pennsylvania, which will operate from their clubhouse, in addition to the Butler County Amateur Radio Public Servce Group in Butler, Pennsylvania, and the Washington Amateur Communications Radio Club in Washington, Pennsylvania. Individual radio amateurs will also be operating from their home stations. In addition, there is a small group of ham radio operators planning portable field operations from South Park in suburban Pittsburgh.

“More than one hundred years ago, many experimenters started delving into a new technology known as wireless, or radio,” said Bob Bastone, WC3O, Radio Officer for the Skyview Radio Society in New Kensington, Pennsylvania. Bastone explained that many of those early pioneers were radio amateurs. “One hundred plus years later, many amateur radio operators are still contributing to wireless technology while also serving their communities and enhancing international goodwill. Congratulations to KDKA Radio, also known in the early years as amateur radio stations 8XK, 8ZZ, and W8XK.”

Bastone said that the special event stations will exchange post cards, called QSL cards, with hams who confirm radio contacts with them.
A commemorative QSL card has been produced with artwork designed by the graphic arts department at KDKA Radio. “We amateur radio operators look forward to contacting thousands of other hams around the world to celebrate this huge milestone in the commercial broadcasting industry,” said Bastone.

The KDKA amateur radio special event stations, operating with call signs K3A, K3D, K3K, and W8XK will be set up at several locations in Pennsylvania during November, inviting the public to come visit while observing the required social distancing protocols. “The special event stations will also help demonstrate ham radio to our communities while our volunteers practice operating skills and station readiness,” said Robert Mente, NU3Q, Emergency Coordinator for the Allegheny County Amateur Radio Emergency Service (ARES). He and his fellow volunteers log many hours each year providing public service and practicing their emergency communications capability. The group provides communication services for The Pittsburgh Marathon, Race for the Cure, the Pittsburgh Vintage Grand Prix, the Great Race, and the American Diabetes Tour de Cure in addition to providing communication support for the American Red Cross and the Pittsburgh National Weather Service office.

For more information about the KDKA centennial and a schedule for the ham radio special event stations including locations, operating frequencies, and how to obtain a commemorative certificate, visit www.kdka100.org and www.qrz.com/db/w8xk. Information is also available in the Special Events Station section both on the ARRL website and in QST Magazine.

We wish to thank II-VI (pronounced two-six) for the use of their corporate facilities in Saxonburg, PA, on the very site where KDKA used to broadcast from for most of the 1930s. II-VI is a global leader in engineered materials and optoelectronic components. For nearly 50 years, they have manufactured innovative products for applications in the industrial, communications, aerospace & defense, life sciences, semiconductor capital equipment, automotive, and consumer markets.

Radio Survivor: “Inside the ‘Little Known’ Voice of America and the U.S. Agency for Global Media”

View of the Capitol Building from the roof of VOA headquarters on Independence Avenue.

(Source: Radio Survivor)

Over the past few months, there’s been a flurry of media attention focused on the United States Agency for Global Media (USAGM). Some reports describe it as a “little-known” agency and, in fact, it may seem mysterious to many in the United States, since it oversees international broadcasting programs all over the world, including Voice of America and Radio Free Europe/Radio Liberty.

USAGM has been in the news following the appointment of new CEO Michael Pack, subsequent personnel changes, and even a congressional hearing on September 24. This week we explore the history of USAGM and talk about some of the recent changes at the organization. We are joined on the show by Jane Curry (Professor of Political Science at Santa Clara University), Mark Pomar (National Security Fellow at Clements Center for National Security at University of Texas, Austin) and Brandon Burke (Associate Archivist at the Hoover Institution Archives). Jennifer Waits and Eric Klein host this week’s episode.

Radio Waves: The “Weird Wide Web” of SW, VOA Whistleblower Complaint, KiwiSDR v RaspberrySDR, and the Portable Operations Challenge this weekend

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!

Many thanks to SWLing Post contributors Steve Lord, Michael Guerin, and the Southgate ARC for the following tips:


Propaganda, Pirates and Preachers: The Weird Wide Web Of Shortwave Radio (The Dork Web)

The world of Shortwave is a world of state-backed propaganda, cults, pirates, and spies. You’ll find every form of freakery and geekery on air. Digital, analogue, even stuff where you can’t tell if it’s digital, analogue, bad music or interference.

[…]In a world of constant connections Shortwave radio may seem anachronistic. But there’s something special in Shortwave and I’d like to show it to you. With a tiny bit of effort and at zero cost you can explore this world from the comfort of your own home.

How Shortwave Shaped Lives

Of all the things I expected to get into, Shortwave radio wasn’t one of them. As a kid I’d listen to my dad’s old valve radio. Strange voices from distant lands floated through the air. Shortwave’s audio quality was terrible even by early 80s standards. There was something magical in hearing distant voices from across Europe and beyond.

I got back into Shortwave listening earlier in the UK lockdown period. Over the past few months I’ve heard stations from as far as Florida, Cuba, Botswana, North Korea and China. I’ve heard signals broadcast from Ascension island in the Atlantic to Tinian island in the Pacific.

Some people will tell you that Shortwave is dead. While it’s passed a 20th century peak there’s plenty happening. In 2002 the National Association of Shortwave Broadcasters estimated that hundreds of millions of households around the world had Shortwave-capable receivers.[]

Six senior Trump admin officials file whistleblower complaint over Voice of America CEO (The Hill)

Six senior Trump administration officials filed a whistleblower complaint with the State Department’s inspector general over allegations that Michael Pack, CEO of the U.S. Agency for Global Media (USAGM), violated federal law and abused his authority, according to a copy of the complaint reported by Politico on Wednesday.

The 32-page complaint includes allegations from six members of the Senior Executive Services at the USAGM accusing Pack, who was confirmed as head of the agency which oversees the state-run network Voice of America in June, of engaging in conduct that “constitutes an abuse of authority and gross mismanagement.”

The six officials who filed the complaint were all placed on administrative leave Aug. 12.

The complaint alleges Pack, who was appointed by Trump, wanted to force out the complainants because they were part of the “Deep State” and had “played a role in the delay” of Pack’s confirmation to his position at the USAGM.

The complaint alleges Pack ordered a close aide to conduct research on the voting history of agency employees, including one of the complainants, Matthew Walsh, the deputy director for operations who was placed on administrative leave. The research “was to be utilized in evaluation of career civil servants’ abilities to carry out the duties of their positions,” the complaint states.[]

KiwiSDR vs RaspberrySDR— a tale of two SDRs (Hackaday via Southgate ARC)

Once you move away from the usual software defined radio (SDR) dongles, you have only a few choices unless you want to drop some serious cash. One common hobby-grade SDR is the KiwiSDR. This popular unit runs Linux and can receive up to 30 MHz. The platform uses a dedicated A/D converter, an FPGA, and BeagleBone computer. Success of course breeds imitators, and especially when you have an open source design like the Kiwi, you are going to find similar devices with possibly different end goals. That’s how the RaspberrySDR came to be. This is a very similar unit to the KiwiSDR but it uses a Raspberry Pi, along with a handful of other differences. What’s different? [KA7OEI] tells us in a recent blog post.

Other than the obvious difference of the computer and all that it entails, the RaspberrySDR has a higher speed A/D (125 MHz vs 66 MHz) and 16-bits of resolution instead of the Kiwi’s 14 bits. This combines to give the Raspberry a wider receive range (up to 60 MHz) and — in theory — better performance in terms of dynamic range and distortion.

[KA7OEI] measures a few key parameters on both devices and arrived at some surprising conclusions. The Kiwi appears to boost signals near its cutoff frequency to compensate for losses in the system. The Raspberry — using adapted software — looks as though it does the same trick, but does it around the Kiwi’s cutoff frequency, which is lower. Probably a software fix could take care of that, of course.

There are also tests of image rejection and front-end overloading. The tests revealed a few problems with signal strength measurement and some other problems with the RaspberrySDR. The biggest issue, though, was that the 16-bit A/D didn’t seem to have better performance. Without proper design, throwing more bits at a problem isn’t always helpful and this appears to be a good example of that.

In the end, the Raspberry looks like a cheap clone of the Kiwi with some benefits, but also some drawbacks. The blog post also covers some open source issues where Kiwi is now saying some parts of their code will only be binary in the future and there has been some difficulty finding all of the Raspberry’s files. If you are looking to buy one, you might not find the name “raspberrysdr” but [KA7OEI] suggests searching for “New 16bit 62M real-time bandwidth network shared SDR receiver” which does turn up some results.

Of course, you can always use a Pi with a more conventional dongle, and that works well enough. If you want to make a Pi just transmit, you can do that with little more than a wire, although the quality might not be perfect.

Portable Operations Challenge (Southgate ARC)

The final rules for the FMH Portable Operations Challenge are now posted on the POC webpage at foxmikehotel.com/challenge/. N1MM+ users, need to select FMHPOC as the contest and VKContest Logger users just POC.

The organisers wish all other contests taking place this weekend success and lots of fun – the bands will be busy again and we’re hoping propagation plays along.

We hope many amateurs give this new-style contest a go whether from a home QTH station or out portable.

Canadian radio stations and TV outlets risk closure (Southgate ARC)

As many as 40 local television outlets and 200 Canadian radio stations could be forced to close in the next three years as the financial pressures faced by media companies intensify under the COVID-19 pandemic, suggests a new study from an industry advocacy group.

The Canadian Association of Broadcasters issued a report on Wednesday warning of potential closures and widespread job cuts as private TV and radio broadcasters face a cumulative projected revenue shortfall of up to $1.06 billion by the end of 2022.

Most vulnerable are the country’s AM radio stations, the report said, as well as other independent private radio and TV operations in smaller markets across the country.

The study, titled “The Crisis in Canadian Media and the Future of Local Broadcasting,” was commissioned by the CAB, which represents the majority of private broadcasters in Canada, and conducted through Winnipeg-based independent media economics consultancy Communications Management Inc.

Bauer closes dozens of regional radio stations in England and Wales (The Guardian)

Replacement of stations with single national outlet described as act of ‘breathtaking cultural vandalism’

Dozens of regional radio stations have been replaced by a single national outlet, in the latest blow to an industry that has seen deep cuts in recent decades.

Outlets across England and Wales owned by Bauer Media – ranging from Wolverhampton’s Signal 107 to York’s Minster FM and Salisbury’s Spire FM – will now broadcast under the single brand Greatest Hits Radio.

Critics said the move was the death knell for traditional mid-sized commercial radio stations, with only a handful of truly independent local radio outlets remaining.

Most of the outlets affected had their own locally employed presenters and management and their own studios in the towns and cities they served. Now, most of the stations on the new network will carry national programming for 20 hours a day.[]

Born at The News: WWJ radio celebrates 100 years since launch as nation’s first commercial broadcaster (Detroit News)

For a behemoth that now dominates the local AM radio dial, its beginnings were surprisingly humble.

One hundred years ago Thursday, WWJ radio — Detroit’s very first station — was born when Detroit News publisher and radio enthusiast William E. Scripps had a 200-watt transmitter set up in a corner of the sports department. (Today? It’s 50,000 watts.) WWJ will air a special show, “WWJ at 100, a Century of News,” at 7 p.m. Thursday to celebrate.

WWJ wasn’t just first in Detroit. Depending on how you slice things, it was the first commercial broadcaster in the U.S., though when it went on the air that Aug. 20 a century back, it was probably picked up by only a few dozen households in possession of what was, at the time, shockingly high-tech radio equipment.

Asked where he’d locate WWJ in American broadcasting history, Specs Howard, founder of the School of Media Arts in Southfield that bears his name, said without hesitation, “Oh, right near the top.”

One-time WRIF program director Fred Jacobs, now head of Jacobs Media Strategies in Bingham Farms, agreed, saying, “It’s really been a remarkable run, especially in a world where brands come and go.”[]

At Voice of America, Trump Appointee Sought Political Influence Over Coverage (KPCW)

At the Voice of America, staffers say the Trump appointee leading their parent agency is threatening to wash away legal protections intended to insulate their news reports from political meddling.

“What we’re seeing now is the step-by-step and wholescale dismantling of the institutions that protect the independence and the integrity of our journalism,” says Shawn Powers, until recently the chief strategy officer for the U.S. Agency for Global Media, which oversees VOA.

Voice of America’s mission is a form of soft diplomacy: to embody democratic principles through fair reporting and to replace a free press in countries where there is none. VOA and its four sister networks together reach more than 350 million people abroad each week.

Since taking office in June, Pack has upended the agency. In a podcast interview last week with the pro-Trump website The Federalist, Pack said he had to take action because many executives and journalists were disregarding the agency’s ethical standards.

“My job really is to drain the swamp, to root out corruption and to deal with these issues of bias, not to tell journalists what to report,” Pack told host Chris Bedford. Pack has declined NPR’s repeated and detailed requests for comment.

But it appears that Pack is, in fact, interested in influencing which stories get told, and how. The senior news editor who oversaw VOA’s standards and practices was reassigned to a corporate position earlier this summer and has since played no role in guiding coverage or scrutinizing stories flagged as problematic.[]
