Radio Waves: Signals from Mars, Two More Hamstronauts, M17 Digital Voice Mode, and Climbing Trees for a Better Signal

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 Troy Riedel, LG, Ron and the ARRL News for the following tips:


Radio Signals from Mars (Spaceweather.com)

How close is Mars? Close enough for radio reception. On Oct. 4th, amateur radio operator Scott Tilley picked up a carrier wave from NASA’s Mars Reconnaissance Orbiter (MRO) circling the Red Planet. Turn up the volume and listen to the Martian Doppler shift:

Tilley is a leader in the field of satellite radio. Dead satellites, zombie satellites, spy satellites: He routinely finds and tracks them. “But this was a first for me,” he says. “A satellite around Mars!”

It’s not easy picking up radio signals from distant planets. NASA does it using the giant antennas of the Deep Space Network. Tilley uses a modest 60 cm dish in his backyard in Roberts Creek, BC. This week’s close encounter with Mars set the stage for his detection.

“MRO’s signal is weak, but it is one of the louder signals in Mars orbit,” says Tilley. “The spacecraft has a large dish antenna it uses as a relay for other Mars missions. With the proximity of Mars these days, it was the perfect time to try.”[]

Two More Astronauts Earn Amateur Radio Licenses (ARRL News)

Although the lockdown of Johnson Space Center (JSC) postponed amateur radio training and licensing over the past 7 months, NASA ISS Ham Project Coordinator Kenneth Ransom, N5VHO, was able to work with all of the new astronaut-class graduates, as well as offer some refresher courses with already-licensed astronauts. Licensed astronauts on the International Space Station (ISS) may operate the on-station ham radio equipment without restrictions.

Astronauts often participate in Amateur Radio on the International Space Station (ARISS) contacts with schools and groups on Earth.

NASA Astronaut Kayla Barron, who completed her introductory course in June and received basic ham radio operations training in late September, recently tested and received the call sign KI5LAL.

European Space Agency astronaut Matthias Maurer passed his amateur radio exam on July 30, and he got his basic ham operations training in July. He now is KI5KFH.

Astronauts Shane Kimbrough, KE5HOD, and Shannon Walker, KD5DXB, completed the refresher course earlier this year. Two other new astronauts are in the queue to take the Technician license exam. — Thanks to Rosalie White, K1STO[]

M17 Aims to replace proprietary ham radio protocols (Hackaday.io)

While M17 might sound like a new kind of automatic rifle (as actually, it is), we were referring to an open source project to create a ham radio transceiver. Instead of paraphrasing the project’s goals, we’ll simply quote them:

The goal here should be to kick the proprietary protocols off the airwaves, replace DMR, Fusion, D-Star, etc. To do that, it’s not just good enough to be open, it has to be legitimately competitive.

Like some other commercial protocols, M17 uses 4FSK along with error correction. The protocol allows for encryption, streaming, and the encoding of callsigns in messages. There are also provisions for framing IP packets to carry data. The protocol can handle voice and data in a point-to-point or broadcast topology.

On the hardware side, the TR-9 is a UHF handheld that can do FM voice or M17 with up to 3 watts out. The RF portion uses an ADF7021 chip which is specifically made to do 4FSK. There’s also an Arm CPU to handle the digital work.[]

Armed with a radio, Cambodian girl climbs tree to access education (SE Asia Globe)

When Cambodian schools closed due to Covid-19, poor internet access and a lack of minority language materials made distance learning in rural communities near impossible. But armed with a simple radio, children are rising above these obstacles to their education

Jumping down from the tree near her home, Srey Ka assumes her spot in the shade underneath as she adjusts the dials on her radio. Her pet piglet remains asleep at her feet, twitching his nose as he dreams, his belly full of leftover rice. Around her, cows meander by, their ringing bells competing with the sound of static from her radio.

While her school is still closed due to Covid-19 regulations, she still wears her Grade 3 uniform as she attempts to locate a signal. She’s listening out for distance learning programmes – six hours of educational radio broadcasts per week for children in Grades 1-3, some of which are in her ethnic minority language.

It was August and Srey Ka had just received a radio from international nonprofit Aide et Action, two weeks before her school reopened as pandemic measures eased in Cambodia in early September.

From the Phnong ethnic minority group, Srey Ka struggled to find learning resources in her language during school closures. Eager to cram as much as she can before returning to school, Srey Ka tied the antenna of her radio to the highest point of a tree to get the best reception. Even a clear radio signal is hard to come by in the small fishing village of Pun Thachea, located along a remote stretch of the Mekong river in Cambodia’s northeast Kratié province.[]

FCC Fines HobbyKing Nearly $3 Million for Marketing Unauthorized Drone Transmitters (ARRL News)

The FCC has issued a Forfeiture Order (FO) calling for HobbyKing to pay a fine of $2,861,128 for marketing drone transmitters that do not comply with FCC rules. An FCC Enforcement Bureau investigation stemmed in part from a 2017 ARRL complaint that HobbyKing was selling drone transmitters that operated on amateur and non-amateur frequencies, in some instances marketing them as amateur radio equipment. The fine affirms the monetary penalty sought in a June 2018 FCC Notice of Apparent Liability (NAL). The FCC said its investigation found that dozens of devices marketed by the company transmitted in unauthorized radio frequency bands and, in some cases, operated at excessive power levels. “Such unlawful transmissions could interfere with key government and public safety services, like aviation systems,” the FCC said.“We have fully considered HobbyKing’s response to the NAL, which does not contest any facts and includes only a variety of legal arguments, none of which we find persuasive,” the FCC said in the FO. “We therefore adopt the $2,861,128 forfeiture penalty proposed in the NAL.”[]

High School Marine Buoy Transmitter Now Active on 20-Meter WSPR (ARRL News)

Phil Karn, KA9Q; Randy Standke, KQ6RS, and members of the Mount Carmel High School Amateur Radio Club (MCHSARC) in San Diego have constructed and deployed an amateur radio marine buoy in the Pacific. The buoy, which transmits WSPR on 14.0956 MHz USB, has already been heard around the continental US, Brazil, Hawaii, Japan, Costa Rica, Australia, and South Africa.

“Over the past year, Randy and I have mentored the MCHSARC in designing and constructing a simple marine buoy that was deployed from the RV Sally Ride [on July 16], about 700 kilometers off the coast of southern California,” Karn said in a post on the AMSAT Bulletin Board. “It is up and transmitting WSPR on 20 meters using the call sign KQ6RS, and is being received all over the US and into Canada and Brazil.” Karn is blogging about the project with updates.

The electronics are the 20-meter WSPR version of the WB8ELK “pico tracker” that has been flown on long-duration balloons. “We removed the solar panels and substituted 21 ordinary alkaline D cells, wired to supply 4.5 V,” Karn explained. “We estimate battery lifetime will be 6 months.”

[…]The first reception report was on July 16 at 12:52:30 UTC from grid square CL89eu, although the current carried the buoy east into CL89fu at 20:32:30 UTC. The buoy (KQ6RS-1) can be tracked on the APRS and WSPRnet sites.[]

Stop Bad Laws Before They Start (Hackaday)

With everything else going on this summer, you might be forgiven for not keeping abreast of new proposed regulatory frameworks, but if you’re interested in software-defined radio (SDR) or even reflashing your WiFi router, you should. Right now, there’s a proposal to essentially prevent you from flashing your own firmware/software to any product with a radio in it before the European Commission. This obviously matters to Europeans, but because manufacturers often build hardware to the strictest global requirements, it may impact everyone. What counts as radio equipment? Everything from WiFi routers to wearables, SDR dongles to shortwave radios.

The idea is to prevent rogue reconfigurable radios from talking over each other, and prevent consumers from bricking their routers and radios. Before SDR was the norm, and firmware was king, it was easy for regulators to test some hardware and make sure that it’s compliant, but now that anyone can re-flash firmware, how can they be sure that a radio is conformant? Prevent the user from running their own firmware, naturally. It’s pretty hard for Hackaday to get behind that approach.[]

Radio Globe: A handy way to explore the world of Internet radio

Many thanks to SWLing Post contributor, Dennis Dura, who shares a link to this fascinating project on the excellent Hackday site:

[…]RadioGlobe lets the user tune in over 2000 stations from around the world by spinning a real globe. It works by using two absolute rotary encoders that each have a whopping 1024 positions available. One encoder is stuck into the South Pole, and it reads the lines of longitude as the user spins the globe.

The other encoder is on the left side of the globe, and reads whatever latitude is focused in the reticle. Both encoder are connected to a Raspberry Pi 4, though if you want to replicate this open-source project using the incredibly detailed instructions, he says a Raspberry Pi 3 B+ will work, too.[…]

Just check out this video of Radio Globe in action!

I love it. It’s like a physical version of the amazing Radio Garden website and app.

Hackaday notes that if you want detailed information about this project, the designer made a series of vlog posts about the build. Click here to check it out on his website. Click here to read through build details on Instructables.

Thank you for the tip, Dennis!

Radio Waves: FEBC at 75 Years, Radio Drama “With a Twist”, Remembering Rufus Turner, and Free Foundation Online Training course

Far East Broadcasting Celebrates 75 Years (Missions Box)

LA MIRADA, CA – Two students attending Southern California Bible College were given the vision to establish the Far East Broadcasting Company, which they incorporated in 1945.

Their initial broadcasting location was in Shanghai in the midst of the Chinese people whom the Lord had laid upon their hearts. The effort was short-lived, however, when China closed its doors to all missionary work in 1948.

Some people would have considered that to be the death of the vision. Not Bob Bowman, John Broger, or their supportive pastor, William Roberts. The vision remained the same, FEBC would have to find a different location.

On June 4, 1948, FEBC regenerated from station KZAS in Manila. By 1949, FEBC was equipped to air broadcasts from the Philippines, across the South China Sea, and into parts of China.

Now celebrating its 72nd year of continuous operations, Far East Broadcasting Company has expanded multiplied times and broadened its ministry to include AM, FM, shortwave, satellite, internet, and other digital technologies.[]

Theaters Return To An Old Art Form — The Radio Drama — With A Twist (NPR)

As theaters across the world have closed because of the coronavirus pandemic, they’ve scrambled to find ways get work to the public.

Some have made archival video of productions available, some have created Zoom plays and some have returned to an old art form — radio drama — but with a digital twist.

In the 1930s, with many people out of work, families huddled around radio receivers to listen to audio plays, like Orson Welles’ famous broadcast, War of the Worlds.

“Orson Welles began his career as a theater actor and director,” says Adam Greenfield, artistic director for New York’s Playwrights Horizons. “And I think he’s able to really utilize the full potential of what audio can do.”

Taking cues from Welles’ success, Greenfield commissioned a new series of audio plays for podcast called Soundstage. He planned to release them this summer, when the theater was dark, but because of the pandemic he hustled them online.

The first podcast released was Prime: A Practical Breviary by songwriter and performer Heather Christian. It’s based on the 6:00 a.m. rite, or breviary, of solo contemplation for nuns and monks.[]

Do you know Rufus Turner (Hackaday)

It is hard to be remembered in the electronics business. Edison gets a lot of credit, as does Westinghouse and Tesla. In the radio era, many people know Marconi and de Forest (although fewer remember them every year), but less know about Armstrong or Maxwell. In the solid-state age, we tend to remember people like Shockley (even though there were others) and maybe Esaki.

If you knew most or all of those names without looking them up, you are up on your electronics history. But do you know the name Rufus Turner?

W3LF

Turner was born on Christmas Day, 1907 in Houston, Texas. At the age of 15, he became fascinated by crystal diodes and published his first article about radio when he was 17. Rufus Turner was–among other things–the first black licensed radio operator (W3LF). He was building and operating radios in Washington D.C., where he was attending Armstrong Tech.

Turner became a licensed professional engineer in California and Massachusetts. You may have even used something that Turner worked on. In the 1940’s, working with Sylvania, he helped to develop the 1N34A germanium diode (you can still buy these if you look around for them).[]

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

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 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.[]

Radio Waves: AM/FM in Teslas, Odd Crosleys, CW Club Membership on the Rise, and 2020 Contest University is Free

Radio Waves:  Stories Making Waves in the World of Radio

“Infotainment Systems” In Cars Portend Safety, Privacy, And Competition Issues (Forbes)

Almost all new cars include so-called “infotainment systems,” which provide navigation and various sources for music and news. Most companies have begun to outsource these systems to the Silicon Valley mainstays such as Apple, Amazon, and Google. The electric car manufacturer Tesla, however, has developed its own infotainment system that is far more integrated with the car itself.

Tesla recently announced an “upgrade,” which would allow users to watch Netflix, Hulu, and YouTube (when the car is parked). This innovation has a flip side: it removes AM / FM radio capabilities. Tesla and other electric car manufacturers claim they have removed AM radio in many of their models due to concerns over interference. But Tesla’s announcement is peculiar because electric engines do not interfere with FM radio reception.

Former FEMA director Brock Long worries that Tesla’s decision could prevent the government from transmitting crucial information in emergencies. Long’s concerns are valid, particularly in a crisis like the ongoing pandemic, when broad communication with the public is necessary to protect national security. AM/FM radio reach places that television and broadband do not, and that is why the government has invested tens of millions of dollars to ensure radio stations can remain on the air during periods of widespread threat to the public – including the current one. As the coronavirus reminds us, our nation still has public safety needs that no amount of technical wizardry can obviate.

The public safety concerns are real, but Tesla decision to remove AM/FM radio also raise the perennial tech issues of privacy and competition.

Tesla has contracts with tech companies such as Spotify and Pandora, many of which are pay services. These tech companies are no doubt pleased that Tesla is contemplating taking out AM/FM radio, which is still the most listened to audio platform—and constitutes meaningful competition. However, these conflicting interests creates mismatched incentives for Tesla.

Because Tesla’s market share is small, and the upgrade is optional, this conduct likely does not rise to anything close to an antitrust violation. However, the vertically integrated model which Tesla is following raises the same type of concerns as when Big Tech firms pick and choose what apps and services customers can favor. If Google, Apple, and Amazon, which have their own podcast and streaming audio services, begin to demand that auto manufacturers carry their services exclusively, then more serious competition problems will arise.[]

Odd Crosley Radios from the 1920s (Hackaday)

You may sometimes see the Crosley name today on cheap record players, but from what we can tell that company isn’t connected with the Crosley Radio company that was a powerhouse in the field from 1921 to 1956. [Uniservo] looks at two of the very early entries from Crosley: the model VIII and the XJ. You can see the video of both radios, below.

The company started by making car parts but grew rapidly and entered the radio business very successfully in 1921. We can only imagine what a non-technical person thought of these radios with all the knobs and switches, for some it must have been very intimidating.

The model VIII had two large knobs, three small knobs, and a switch. Oddly enough there were very few markings on the knobs, as you were expected to know how to use a tuned RF radio. The large knobs were for tuning capacitors and the switch was for coil taps, while the three small knobs controlled the tube filament supplies.[]

Radio Waves: Tribute to Gene Pell, Dangerous AM Demonstration, White House Criticism of VOA, and Essex Online Classes Break Records

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 Troy Riedel, Dennis Dura, and Dan Robinson for the following tips:


Ernest Eugene “Gene” Pell 1937-2020 (Radio Free Europe)

As noted in this obituary published by his hometown newspaper, The Paducah Sun, Ernest Eugene “Gene” Pell, 83, died quietly on April 7, 2020, at his home near Syria, after a 3-year battle with cancer. Pell served as President and Chief Executive Officer of Radio Free Europe/Radio Liberty (RFE/RL) from 1985-1993, leading the Radios during the peaceful revolutions that occurred in Eastern Europe and the Soviet Union from 1989-1992.

In Tribute to Gene Pell

In 1989, we who were privileged to serve in the management of RFE/RL as Gene Pell’s colleagues watched the awesome professionalism of RFE/RL’s broadcasters as peaceful revolution swept from the Baltics to the Balkans, and the Radios helped each country share with others the power – even the slogans – of peaceful protest, and the wisdom of restraint by police and armed forces.

Romania was a tragic exception. Ceaucescu’s regime was doomed by RFE’s broadcast of a recording of the shooting of civilians protesting in Timisoara. As Ceaucescu fled Bucharest, and violence by unknown combatants erupted, Gene ordered a million watts of shortwave power from our transmitter stations across Europe diverted to the Romanian service. Before long, Romanian army commanders seeking to restore calm established phone contact with the service in Munich.

In the immediate aftermath of the liberation of Eastern Europe, and the 1991 collapse of the Soviet Union, Gene saw the need and found the resources to open bureaus across the region and begin on-the-ground reporting by talented local journalists – and local rebroadcasting of RFE/RL programming.

And he persuaded the U.S. government to allow RFE/RL for the first time to broadcast to the former Yugoslavia, during the Bosnian War, with a new, multi-ethnic service led by Nenad Pejic*.

On Gene’s watch, Lennart Meri, Foreign Minister of a newly free Estonia, nominated RFE/RL for the Nobel Peace Prize.

Gene’s leadership was crucial as another struggle soon ensued, this time in Washington, as efforts arose to save the federal government money by shrinking or closing the Radios, on the premise that if Europe was free, why did we need Radio Free Europe (and Liberty)? Support from new democratic leaders across the region, notably from Lech Walesa and Vaclav Havel, helped convince a Presidential Commission addressing this question that the Radios’ mission should not end but evolve, as it has.

The views of these freedom leaders were decisive in keeping RFE/RL on the air and positioned to win the enormous multi-media audience it enjoys today. Gene Pell’s vision is alive for future generations.

Two of my closest colleagues, Ross Johnson and Kevin Klose, join me, as I am sure many others would, in saluting Gene for his contribution to a freer world.

A Dangerous Demonstration of the Power of Radio (Hackaday)

Terrestrial radio may be a dying medium, but there are still plenty of listeners out there. What would a commute to or from work be without a check of “Traffic on the Eights” to see if you need to alter your route, or an update of the scores from yesterday’s games? Getting that signal out to as many listeners as possible takes a lot of power, and this dangerous yet fascinating demo shows just how much power there is on some radio towers.[]

White House Criticism of VOA, Unprecedented in its 78 year History (Public Diplomacy Council)

The Voice of America is the nation’s largest publicly-funded international broadcaster, reaching 280,000,000 multimedia users in 47 languages each week, many of whom access it daily for honest, balanced and accurate world news.

To most senior VOA officials, past and present, including this writer, an unsigned White House blog on April 9, 1600 Daily, omitted or misstated vital information about the scale and original date of the coronavirus outbreak in mainland China. That blog asserts in a bold headline: “Voice of America spends your money to speak for authoritarian regimes.”

But that attack was just the beginning.

President Trump went even further at his daily news briefing on April 15, largely devoted to the coronavirus. “If you heard what’s coming out of the Voice of America, it’s disgusting”. The President then assailed Congress for failing to take up his nomination of conservative Michael Pack as chief executive of all five U.S. funded multimedia organizations, the U.S.Agency for Global Media, until recently known as the U.S. Broadcasting Board of Governors.

The USAGM is the oversight body of five overseas multimedia U.S.-funded networks: VOA, Radio Free Europe/Radio Liberty, Radio Free Asia, the Middle East Broadcasting Network in Arabic, and Radio/TV Marti in Spanish to Cuba. Research in approximately 100 countries indicates that collectively, the five networks reach 350,000,000 people abroad every week.[]
