Radio Waves: New Ham Radio Store, SDR Market worth $14.5 billion by 2025, Retaining 87.7 FM, and Hard-Core-DX now on Slack

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 Tracy Wood, Bill Patalon, Dennis Dura, and Mike Agner for the following tips:


Amateur Radio Field Day synchronized with radio store’s Grand Opening (Ramona Sentinel)

Ham radio hobbyists will test their emergency preparedness skills alongside All Day Radios’ Grand Opening celebration in Ramona next weekend.

The Amateur Radio Field Day, a national emergency preparedness activity sponsored by the American Radio Relay League (ARRL), will be held in Ramona from 11 a.m. Saturday, June 26 and continues for 24 hours until 11 a.m. Sunday, June 27.

All Day Radios co-owner Peter Von Hagen will coordinate his Grand Opening in sync with Field Day from Friday through Sunday. The store is at 2855 state Route 67 between Dye Road and Hope Street, and Field Day will be held next door.

Von Hagen said the object of Field Day, held annually the fourth weekend in June, is to communicate on as many stations on amateur bands as possible to test the capabilities of communications equipment. Operators will be using backup sources of power such as solar power and batteries, he said.[]

Software Defined Radio Market worth $14.5 billion by 2025 (Markets and Markets Newsletter)

The demand for software defined radios, especially in the commercial applications, such as telecommunication, transportation, and commercial aviation, has been affected to a great extent. Due to precautionary measures undertaken by many countries to stop the spread of COVID-19, several public/private development activities have been stopped, resulting in a drop in demand for software defined radios. However, this trend seems to vary from country to country. For instance, the demand for software defined radios in Europe and the Asia Pacific has been affected by the pandemic owing to the stoppage of development activities.

Based on application, the commercial segment of the software defined radio market is projected to witness the substantial growth during the forecast period

In terms of application, the market is segregated into commercial and defense. The rising usage of SDRs in commercial applications including aviation communication, marine communication, transportation, telecommunication is supporting the segment growth. Software defined radios are predominantly used in Air Traffic Control (ATC), transportation, and telecommunication applications. They are easily upgradable and provide high data transmission rate that further enhances its usage for commercial segment.

Cognitive/ Intelligent radio sub segment of the software defined radio market by type is projected to witness the highest CAGR owing to increasing improvements in cognitive radio products.[…]

FCC Report 6/13: Has A STA Based Doorway Been Cracked Open To Retain 87.7 FM Operations? (Radio Insight)

The FCC has sent another reminder to licensees of analog low power television stations regarding the July 13 drop-dead date. If an analog LPTV has not applied for a digital CP by that date its license will be cancelled and those that have Construction Permit’s but will not be ready to broadcast digitally will need to file a waiver request but still will be required to turn off their analog signal on the 13th and cease operation until ready to begin operating with their digital facilities.

This will of course affect the thirty something LPTV’s on analog channel 6 operating as radio stations on 87.75 MHz. While some of these signals will be moving to other channels, many will be remaining on channel 6 and have spent the past few years seeking loopholes to continue to broadcast an analog audio signal past the digital conversion deadline. Venture Technologies Group, which owns five affected stations, threw the door wide open this week with the grant of a six month STA for its KBKF-LD San Jose CA. KBKF-LD, which is leased to Educational Media Foundation to air its “Air 1” network, will be permitted to continue to offer an analog audio signal on 87.75 FM in its ATSC 3.0 digital video signal.[]

Introducing: Hard-Core-DX Slack Chat (Hard-Core-DX)

From: Risto Kotalampi

Hi all,

Hard-Core-DX has been a pioneer in connecting shortwave listeners for nearly 30 years now. In its core it has been emailing lists and web sites and some other experiments which have either spun to become popular on their own (e.g. various ham related spotting sites or Online Log which is very popular in Finland) or not. Today we wanted to try to branch out into chat using Slack.

This is not the only chat there is… IRC, Facebook, Whatsapp etc have small circles for shortwave listeners but they have all been closed systems and not enabling an environment that can be used across devices and have conversations about any topics we choose. In the corporate world Slack has revolutionized communications amongst colleagues and partners in different companies. Much of work in U.S.A. small companies happens nowadays in Slack and not so much in emails.

Hard-Core-DX has signed up and created it’s very own Slack service.
If you want to join the HCDX Slack, please click this link and create your own HCDX Slack account:

https://join.slack.com/t/hard-core-dx/shared_invite/zt-rn83gamf-_UCfo9LYUVmoIBhb0~3cSg

Some basic rules of the Slack service:

  1. When you join it, you will see some channels that have been created already. You can join them or if you can’t find the topic you’d like to chat about, please create your own.
  2. HCDX will not be in the business of moderating what people are creating or discussing. If you create a channel, you will choose the policies of the discussion.
  3. This can naturally invite some abuse. We will deal with it with Slack’s policies as time comes.
  4. You are welcome to invite your DX friends to the HCDX Slack and grow the community. Invite happens from menu in upper left corner and link “Invite people to Hard-Core-DX”
  5. Let’s keep subjects within shortwave radio, broadcast, utility, pirate DXing & ham radio if possible to keep the service relevant to us
  6. This is an experiment… if it doesn’t gain popularity or becomes a burden, we will shut it down. But for now, if you want to experiment and see if this is where you want to chat with your DX friends, join the fun.

The silence of Radio Canada International (Open Canada)

The former head of CBC News laments the evisceration of CBC’s international service and Canada’s shrinking voice in the world

For a country that once regarded itself as one of the world’s leading middle powers, Canada’s voice on the international scene is a strikingly quiet one these days. It reminds me of the line from that famous “dead parrot” sketch in Monty Python: “bereft of life, it rests in peace.”

The latest sign of this is the decision by CBC/Radio-Canada to implement changes that have effectively smothered Radio Canada International (RCI), its fabled global audio and online service that has helped serve as “Canada’s Voice to the World” for more than a half century.

In a December announcement replete with CBC doublespeak, the CBC unveiled a “major transformation” of RCI that, it claimed, would ensure RCI remains “a strong and relevant voice” in this century’s media landscape. Not surprisingly, the practical impact of these changes is precisely the opposite.

Flipping RCI’s historic mission on its head, the service will now focus more on ethnic minorities within Canada rather than on continuing to produce programs tailored uniquely for international audiences. More than half of RCI’s beleaguered staff have been laid off.

This latest CBC battering of RCI — a pattern that has gone on for decades — triggered considerable criticism. In February, a group of 32 prominent Canadians sent an open letter to Prime Minister Justin Trudeau and other senior government ministers urging that the CBC scrap its planned strategy and appoint an independent committee to plan a rebuild of the international service: “In an interconnected world in search of truth, facts and honest journalism, countries like Canada cannot abdicate their role on the world stage.” Its signatories included former prime minister Joe Clark, former foreign affairs minister Lloyd Axworthy, former UN ambassador Stephen Lewis, actor Donald Sutherland and author Naomi Klein.

Live streams go down across Cox radio & TV stations in apparent ransomware attack (The Record)

Live streams for radio and TV stations owned by the Cox Media Group, one of the largest media conglomerates in the US, have gone down earlier today in what multiple sources have described as a ransomware attack.

The incident took place earlier this morning and impacted the internal networks and live streaming capabilities for Cox media properties, such as web streams and mobile apps. Official websites, telephone lines, and normal programming remained running but some live programming could not go on air as scheduled.

“This morning we were told to shut down everything and log out our emails to ensure nothing spread. According to my friends at affiliate stations, we shut things down in time to be safe and should be back up and running soon,” a Cox employee shared in a private conversation earlier today.

Asheville Radio Museum reopens to public after months-long pandemic closure (WLOS)

The Asheville Radio Museum reopened to the public Saturday, June 5, following a months-long closure due to the pandemic.

The museum, located on the campus of A-B Tech, and closed in November to follow the campus’s COVID-19 protocol to protect students and staff.

Asheville Radio Museum boasts a premier collection of vintage radios with the goal to educate, demonstrate and fascinate visitors about the importance of the radio, which was named the second most important invention of the twentieth century on the Science Channel.

Saturday’s reopening was highlighted by the addition of newly-procured radios as well as refreshed displays throughout the museum. Continue reading…

Aluminium-Ion battery development (Southgate ARC)

The Graphene Manufacturing Group in Brisbane, Australia together with the University of Queensland have according to the GMG website developed a Graphene Aluminium-Ion Battery energy storage technology that has up to three times the capacity of a lithium-ion battery and can charge up to sixty times faster.

The battery was created by inserting aluminium atoms into perforations made in graphene planes.
The company claims that because the batteries lack an upper Ampere limit that would otherwise cause spontaneous overheating, the batteries are also safer. The stable base materials also facilitate their recycling later.

The company hopes to bring these cells to market by the end of 2021 or early 2022

HF-START Web Tool: A new web-based, real-time shortwave radio propagation application

Many thanks to SWLing Post contributor, Tracy Wood, who shares the following journal abstract from EurekaAlert.com:

Commencement of shortwave propagation simulator (HF-START) service

Demonstrating radio wave propagation paths between any two points based on real-time space weather information

NATIONAL INSTITUTE OF INFORMATION AND COMMUNICATIONS TECHNOLOGY (NICT)

[Abstract]

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), in collaboration with Electronic Navigation Research Institute, National Institute of Maritime, Port and Aviation Technology (ENRI, Director General: FUKUDA Yutaka) and Chiba University (President: TOKUHISA Takeshi), has started the service of shortwave propagation simulator (HF-START). It provides real-time shortwave propagation that reflects real space weather information from ground-based observations and model calculations. The HF-START web system has been successfully developed and is now available at https://hfstart.nict.go.jp/.

The web calculation function of this system allows shortwave propagation between any two points in Japan based on real-time GNSS observations and between any two points on the Earth based on model-based space weather information. Real-time estimation is possible. The calculation in the past and up to about 1 day ahead in the future is also possible. In addition to amateur radio, HF-START is expected to benefit efficient frequency operation of aviation communications that relies on shortwave in the polar route.

[Background]

Communication and positioning technologies play an important role in social infrastructure in various fields today. The ionosphere has regular temporal cycles and fluctuates greatly every day associated with solar activity and space environment. Of benefit to us is the fact that ionosphere is good at refracting shortwave, which is why we can hop shortwave signals off the ionosphere to communicate with people over large distances.

Shortwave band has been used for communication and broadcasting for a long time, and are still widely used in radio broadcasting, aviation communication, amateur radio, etc. Ionospheric variation, however, has a great influence on the propagation of radio waves. Communication environment such as the communication range and usable frequency changes significantly due to the influence of the ionospheric fluctuation. Thus, fluctuations in the ionosphere affect the operation of shortwave broadcasting, aviation communications, and amateur radio.

There have been websites that provide estimated information on how radio wave propagation changes due to such ionospheric fluctuations. The problem is that it is based on a simple model and does not reflect realistic ionospheric fluctuations.

[Achievements]

We have developed a shortwave propagation simulator HF-START that estimates and provides shortwave propagation information in real-time under realistic ionospheric fluctuations based on ground-based observations and model calculations. We open real-time information estimated by HF-START, and the web application at https://hfstart.nict.go.jp/.

Figure 1 shows an example of visualization of shortwave propagation by HF-START. In this system, the user can check the radio wave propagation information that is updated in real-time. As shown in Figure 2, the user can also use the web application to estimate and visualize radio wave propagation by specifying any frequency in the range of 3-30 MHz, any two points on the Earth, and any transmission angle. The date and time can be set retroactively to the past (after 2016), to the real-time, and in the future (up to about 1 day ahead).

The system can be used to visualize the radio propagation path and clarify whether it is affected by space weather when the shortwave you are using does not reach the destination, or when you can listen shortwave broadcasted from the far source that normally you cannot hear. Furthermore, in addition to amateur radio, it is expected to benefit efficient frequency operation of the aircrafts that use shortwave in polar route.

[Future Prospects]

We are conducting research and development to extend the HF-START to estimate radio wave propagation not only in the shortwave band but also in other frequency bands. In addition, we will evaluate the simulator accuracy and improve it by comparing it with radio wave propagation observations.

NICT has been providing information related to communications, satellite positioning, and radiation exposure since November 2019 as a member of the Global Space Weather Center of the International Civil Aviation Organization (ICAO). With the HF-START service, we expect to improve the information provided to directly relate to communications, such as communication range information.

As the abstract mentions, you can use the tool online now via the HF-Start Web Tool.

With schools shut by pandemic, solar radios keep Kenyan children learning (Thomson Reuters Foundation)

Solar-powered radios have been distributed to the poorest homes that lack electricity access, with lessons broadcast daily during the COVID-19 crisis – and perhaps beyond

TANA RIVER, Kenya, Dec 23 (Thomson Reuters Foundation) – Deep in Tana River County, in southeastern Kenya, a group of pupils formed a circle around their teacher, jotting down notes as they listened to a Swahili diction lesson coming from the solar-powered radio sitting in their teacher’s lap.

The radio the children from Dida Ade primary school gathered around was one of hundreds distributed for free to the most vulnerable households in the semi-arid region east of Kenya’s capital, Nairobi.

The radios allow children without internet access or electricity at home to continue studying while schools are closed to slow the spread of COVID-19, in a project that could also help children stay in education after the pandemic.

Funded by the Zizi Afrique Foundation, a Kenyan non-governmental organisation that produces research to drive education policy, the solar-powered radios also come with bulbs for household lighting and slots for phone-charging.

When schools across Kenya shut in March to slow the spread of COVID-19, Zizi Afrique did a survey in Tana Delta sub-county and found that just over one-fifth of households owned a radio and only 18% had access to electricity.[]

Synchronous AM’s Long and Tortuous History (Radio World)

AM boosters repeatedly have been proven effective, but the FCC consistently has declined to allow their wide use

With AM improvement on the radars of broadcasters and the FCC, there has been renewed talk in recent years about the subject of AM “boosters,” the carrier frequency synchronization of multiple transmitters. The commission opened a comment period on AM boosters in 2017.

It wasn’t the first time the FCC has explored this topic and failed to act on it. In fact, AM boosters have been proposed and tested dozens of times since the early days of radio. But even though the technology has repeatedly been proven effective, the commission consistently has declined to allow the operation of AM boosters on anything more than an experimental basis, for a variety of reasons.

Let’s take a moment to look back at the history of this beleaguered technology.

BOSTON REPEATER
In 1930, crystal control of transmitter frequencies was still an emerging technology, and the allowable frequency tolerance of a broadcast transmitter was +/- 500 Hz. Two stations operating on the same channel, even if widely geographically separated, could generate a heterodyne beat note of up to 1 kHz, a disconcerting annoyance to listeners.

Consequently, only a few stations were allowed to operate nationwide evenings on any one channel at the same time. Further, there were 40 clear-channel stations, each one having exclusive nationwide use of its frequency. As most of these clear-channel stations were network affiliates, many channels were wastefully duplicating the same programs.

In 1929, the respected radio engineer Frederick Terman proposed that, if all stations of the two networks (NBC and CBS) could synchronize their carrier frequencies within +/- 0.1 Hz to eliminate the heterodyne beat notes, they could all coexist on a single channel per network, freeing up dozens of channels for new stations.

Synchronization was first proved successful by the Westinghouse station WBZ in Springfield, Mass. Broadcasting from the roof of the Westinghouse factory, WBZ failed to cover Boston, so WBZA was opened as a Boston repeater. The two stations were synchronized on the same frequency beginning in 1926, using a tuning fork as a frequency reference.[]

FM Radio on Jupiter, Brought to You by Ganymede (EOS)

Another first from NASA’s Juno spacecraft: the detection of radio emissions from the Moon Ganymede, over a range of about 250 kilometers in the polar region of Jupiter.

Louis et al. [2020] present exciting new observations of radio emissions on Jupiter from the NASA Juno spacecraft – the first direct detection of decametric radio emissions originating from its Moon Ganymede. These observations were made as Juno crossed a polar region of the Giant Planet where the magnetic field lines are connected to Ganymede.

The radio emissions were produced by electrons at relativistic energy (a few thousand electron volts) in a region where the electron’s oscillation frequency (“plasma frequency”) is much lower than its gyration frequency (“cyclotron frequency”). Such electrons can amplify radio waves very close to the electron cyclotron frequency very rapidly, via a physical process called electron cyclotron maser instability (CMI). They can as well produce aurora in the far-ultraviolet – which was also observed by the camera on Juno.

Juno was traveling at a speed of approximately 50 kilometers per second, and it spent at least about 5 seconds crossing the source region of the emission, which was therefore at least about 250 kilometers in size.

The observed decametric radiation on Jupiter is clearly the “shorter cousin” (in wavelength) of the auroral kilometric radiation on both Earth and Saturn: the CMI being responsible for their production on the three planets.

New WSJT mode Q65 (Southgate ARC)

WSJT-X 2.4.0 will introduce Q65, a digital protocol designed for minimal two-way QSOs over especially difficult propagation paths

On paths with Doppler spread more than a few Hz, the weak-signal performance of Q65 is the best among all WSJT-X modes.  Q65 is particularly effective for tropospheric scatter, ionospheric scatter, and EME on VHF and higher bands, as well as other types of fast-fading signals.

Q65 uses 65-tone frequency-shift keying and builds on the demonstrated weak-signal strengths of QRA64, a mode introduced to WSJT-X in 2016.  Q65 differs from QRA64 in the following important ways:
•A new low-rate Q-ary Repeat Accumulate code for forward error correction
•User messages and sequencing identical to those in FT4, FT8, FST4, and MSK144
•A unique tone for time and frequency synchronization.  As with JT65, this “sync tone” is readilyvisible on the waterfall spectral display.  Unlike JT65, synchronization and decoding are effective even when meteor pings or other short signal enhancements are present.
•Optional submodes with T/R sequence lengths 15, 30, 60, 120, and 300 s.
•A new, highly reliable list-decoding technique for messages that contain previously copied message fragments.

AM Radio Transmitter Sites Now Valuable Real Estate for Logistics Industry (Transport Topics)

The familiar real estate adage “location, location, location” rings true these days for huge tracts on the outskirts of major cities — sites that for decades housed AM radio towers but that today command top dollar as e-commerce fuels rising demand for new warehouses and logistics centers.

Look no further than the $51 million sale of a five-acre parcel in Queens, N.Y., where an AM radio station will eventually abandon its existing tower and transmitter site, and move it.

New York radio station WFME’s owner, Nashville, Tenn.-based Family Radio, sold its AM transmitter site to Prologis, a San Francisco developer that specializes in building warehouses for companies looking to expand final-mile capability.

This property is situated near the Long Island Expressway, the Brooklyn-Queens Expressway, the Queens-Midtown Tunnel, and La Guardia and JFK airports. The spot’s current value as a logistics hub far outstrips its importance to a broadcast outlet that didn’t register in New York’s most recent radio ratings book.

“Long term, we see this as a strategic move that adds to our growing footprint of high-quality logistics space that offers quick and easy access to consumers.” said Jeremiah Kent, Prologis senior vice president of value added investments. “In one of the most densely populated markets in the world where demand for logistics real estate is high and land is scarce, Prologis is well-positioned to respond to the acceleration of e-commerce and consumers’ expectation for same- and next-day delivery services.”

The rising value of these locations is being driven by changing consumer habits and rapid technological evolution. Sites on the edge of town that in radio’s heyday were cheap and plentiful can now house vital links in a supply chain propelled by technology that was hard to imagine back in AM’s early days.[]

USAGM CEO Names New Leaders for RFE/RL, OCB (VOA)

WASHINGTON – The U.S. Agency for Global Media announced that former VOA journalist Ted Lipien will return to run Radio Free Europe/Radio Liberty and Jeffrey Scott Shapiro, the current acting director at the Office of Cuba Broadcasting, will become director.

The appointments follow USAGM CEO Michael Pack’s December 9 announcement that former Voice of America director Robert Reilly would return to lead that network.

Lipien joined VOA in 1973 and worked as the chief of the Polish language service and later as a senior news and marketing executive until 2006. For 10 years, Lipien worked in Munich and Prague as the Eurasia regional marketing director, helping VOA and RFE/RL place programs on stations across the region. In an announcement sent to staff, he recalled listening to Radio Free Europe while growing up in communist Poland.

“I’m honored, and humbled, to be entrusted with helping this storied organization continue to break the hold of censorship and give voice to the silenced,” he wrote.

Since leaving U.S. broadcasting, Lipien has been a vocal critic of VOA’s and USAGM’s previous leaders. He has also defended Pack’s tenure as CEO, saying Pack has focused on correcting long-running issues of bias and mismanagement at the networks.

Radio Free Europe/Radio Liberty is a nonprofit multimedia broadcasting organization funded by U.S. Congress grants. Based in Prague, it serves as a surrogate media source in 27 languages, mostly in places where a free press remains either banned or not fully established.

Jeffrey Scott Shapiro has been with the Office of Cuba Broadcasting since July 2017. In announcing Shapiro’s new position, Pack cited his deep connections to local communities in South Florida and his track record in producing objective news.

“Transmitting objective news and information to the island plays a critical role in moving toward a free Cuba, and it is a privilege to be a part of such an important mission,” Shapiro wrote in a published statement.

The Office of Cuba Broadcasting oversees Radio and Television Marti, based in Miami, Florida. The network provides news, information and analysis to the people of Cuba via satellite television and shortwave radio, as well as flash drives, DVDs and text messages.

Pack was confirmed by the Senate as CEO in June with a three-year term and fired several news executives upon his arrival. He later declined to testify before a House of Representatives panel examining his decisions at the agency, including his decision to fire the heads of RFE/RL, Radio Free Asia and OCB, and replace their boards. The then-director of VOA, Amanda Bennett, resigned two days before Pack joined the agency.

Last month a federal judge granted a preliminary injunction prohibiting Pack and other USAGM officials from interfering with the editorial independence and First Amendment rights of journalists at VOA and other networks they oversee. The ruling still allows Pack to appoint leaders of those news networks to oversee them.

The November 20 court order prohibits the CEO and other defendants from communicating directly with journalists at the networks without the consent of their directors. The order is part of a lawsuit filed by five USAGM officials whom Pack placed on administrative leave in August. The suit accuses Pack and his political appointees of unlawful actions and of violating the First Amendment and a statutory firewall set up to ensure editorial independence. Pack has said the lawsuit is “without merit” and that all of his and his team’s decisions and actions are “correct and lawful.”

Earlier this month, a federal office set up to protect whistleblowers ordered USAGM to investigate allegations of wrongdoing by its own top officials.[]

All new car radios to have digital terrestrial radio (Southgate ARC)

From today, people purchasing new passenger vehicles across Europe will be able to benefit from the advantages of digital radio – greater choice, clearer audio and enhanced data services.

Article 113, Annex XI in the EECC states that “Any car radio receiver integrated in a new vehicle of category M* which is made available on the market for sale or rent in the Union from 21 December 2020 shall comprise a receiver capable of receiving and reproducing at least radio services provided via digital terrestrial radio broadcasting”.

The regulation applies to all EU member states – regardless of the status of DAB in each country.

Despite the impact of Covid-19, Germany, France, the UK, Italy and Denmark have already introduced laws mandating digital terrestrial radio in cars and other countries are expected to follow shortly.

In the first half of 2020, over 50% of new cars sold in Europe included DAB+ as standard – a number that is expected to reach 100% by the end of 2021 as DAB+ adoption continues to grow across Europe.

More information and regular updates on the EECC directive and its implementation across Europe is available on the WorldDAB EECC factsheet.

*Motor vehicles with at least four wheels designed and constructed for the carriage of passengers

North Korean fisherman publicly executed for listening to foreign radio (The New Daily)

A North Korean fishing boat captain has been publicly executed for listening to banned foreign radio stations while at sea.

The man, only known by his surname Choi and said to have been in his 40s, was killed by firing squad in front of 100 boat captains and fisheries executives, according to a Radio Free Asia report.

Choi, who owned a fleet of more than 50 ships, is thought to have been turned in by a crew member after they turned against him.

According to the RFA report, Choi ultimately confessed to authorities and was charged with “subversion against the party”.

“In mid-October, a captain of a fishing boat from Chongjin was executed by firing squad, on charges of listening to Radio Free Asia regularly over a long period of time,” a North Korean law enforcement official told RFA.

“They publicly shot him at the base in front of 100 other captains and managers of the facility’s fish processing plants. They also dismissed or discharged party officials, the base’s administration and the security officers who allowed Choi to work at sea.”

The network said the fishing boat captain began his habit of tuning into foreign radio stations, including RFA, while serving as a radio operator in the military. He had listened to RFA – a US-government funded network that broadcasts in Korean – for 15 years.

“The security authorities decided then that the time to re-educate him had long past, so they executed him by firing squad,” the source said.

“It seems that the authorities made an example out of Choi to imprint on the residents that listening to outside radio stations means death.”[]

SpaceX Launches Latest Satellite For SiriusXM Radio (Spaceflight Insider)

On Sunday December 13, a SpaceX Falcon 9 rocket successfully lifted off from SLC-40 at Cape Canaveral Space Force Station in Florida, carrying the SXM-7 satellite to a geostationary transfer orbit. The flight came two days after SpaceX’s first launch attempt on Friday, which was aborted at t-minus 30 seconds. The company tweeted the reason for the scrub, “Standing down from today’s launch attempt to perform additional ground system checkouts.” While SpaceX did not point to a specific reason for the hold call, it can be assumed that either the onboard computers or ground controllers found something off-nominal in the final seconds before liftoff.

[…]The payload, the SXM-7 satellite, is the latest addition to Sirius XM’s constellation of satellites aimed at delivering an extensive library of music and entertainment to most parts of the world. SXM-7, along with its sister satellite SXM-8 launching in 2021, are aiming to replace the company’s aging XM-3 and XM-4 satellites. Contracted and built by Maxar for Sirius XM, the 7,000 Kilogram satellite is based on the SSL-1300 Bus and utilizes a host of S band transponders to provide satellite radio to customers in North America.

“Maxar and SiriusXM have worked together for more than two decades to build world-class digital audio radio satellites that bring entertainment to almost every new car in America,” said Megan Fitzgerald, Maxar’s Senior Vice President of Space Programs Delivery. “We are proud to have built the latest addition to the SiriusXM constellation and look forward to the launch of their next Maxar-built satellite, SXM-8, next year.”[]

CHU, Canada’s Time Station (Radio World)

Look inside the facility that broadcasts voice time signals in two languages

It is nestled in a farmer’s field in southwestern Ottawa, Canada, in a protected area known as the Greenbelt, surrounded by miles of sprawling suburbia.

It is CHU, Canada’s own automated time station.

Operating from a 1940s-era transmitter building and three vertical antenna towers, CHU broadcasts automated voice time signals in both English and French 24/7.

Its broadcasts are transmitted on 3.33, 7.85 and 14.67 MHz, and are heard through central/eastern Canada and the eastern United States, plus many other areas of the planet on a regular basis.

CHU’s time service is operated by Canada’s National Research Council, with the station being remotely controlled from the NRC’s Montreal Road headquarters central Ottawa some 12 miles away. The time signals are based on CHU’s trio of atomic clocks on-site, which are constantly checked against the atomic clocks at NRC headquarters.

“We are equipped with 1960s-era 10 kW transmitters that have been highly modified over the years,” said Bill Hoger. He is the Research Council officer who maintains the unmanned station as part of his overall duties along with two other off-site technicians.[]

We sincerely apologize for the inconvenience caused to customers and retailers who are waiting for ID-52.

We will inform you about the timing of resuming production as soon as it is confirmed.

We are doing our utmost to resume production as soon as possible, and we appreciate your understanding.

New Type of Broadcast Receiver (LinkedIn Post)

There has been a lot of testing over last few month, with the new working prototype AM receiver. It has taking almost two years to get to this point with a lot of testing to find out what works and what does not.

The performance on Long wave and Medium wave is outstanding with the external loop configuration, this has many advantages over a ferrite rod antenna design. The Short wave performance is OK, where the front end RF transformers need to be improved with more testing. It out performs my Tecsun PL-398 that uses Digital Signal Processing (DSP), and comes close to what is possible within the high noise floor that you get in buildup areas.

The adaptive processing works very well, where you can set in software to work based on the signal level and if there is a pilot tone been detected (stereo indicator), this works for both the AM bands and for FM. As with the adaptive processing the noise reduction also works with both AM and FM bands, that has been use with Short wave and Long wave stations. The de-emphasis cave is design for 50 ?s, to pass a wider modulation bandwidth through up to 12.5 kHz.

The Denon TU-680NAB has been the reference receiver throughout all the testing to get to this test point. As this was designed for the high end audio market in the 1990’s, to provide the best possible performance for HiFi systems of the day.

[…]This will be marketed as a high end broadcast receiver, the aim is to stay well clear of low cost products from China, that are all too common these days. This is a Canadian product, showing that there are many new ideas and what possible in this area of development. With all these advancement it possible to provide a high quality music programming using AM radio that sounds as good as FM, with the advantages of larger coverage areas.[…]
