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 Marty, Dennis Dura, Dave Zantow, Al Holt, and Rich Cuff for the following tips:

Build a ham radio voice keyer for the backpack (Nuts and Volts)

I have an MFJ-434 voice keyer that has saved a lot of wear and tear on my vocal cords over the years. It has been a big asset during ham radio contests and when I’ve been calling CQs with reduced power (QRP) transceivers.

One of my new favorite pastimes has been operating QRP radios from remote off-the-grid locations. Most of the time, it’s important to pack only the bare essentials for these mini-DXpeditions. I have never taken the MFJ keyer, primarily due to its size. An “accessory” measuring 6-1/2 x 7 x 2-1/2 inches fills up a lot of backpack. It also weighs a pound and a half. On the other hand, I’m absolutely positive the lack of a keyer has resulted in fewer radio contacts. I always run out of voice before I run out of battery.

Last winter, I was packing a QRP “Go Box” for a trip to Florida. Since that stay was planned to last longer than my normal field trips, I decided to take my MFJ keyer for its first outing. What a difference that keyer made! In less than three months, I worked stations in 31 countries and five continents running a 10 watt transmitter and a dipole antenna!

The enormous number of contacts warranted a closer look at a keyer for shorter field trips. The MFJ-434 has 11 buttons to push, three potentiometers to turn, and two LEDs to show me the keyer is doing what I told it to do. Could I get by with fewer amenities and shrink the size, weight, and power requirements to something more backpack friendly? It was worth an investigation.

The MFJ keyer stores five messages. For field operation, I could live with a single CQ. I found a 20 second record-playback module on eBay for $2.59.

I also found a repeat-cycle timer (variable on and variable off delays) on eBay for $2.38. I could use it to “turn on” the playback message, then turn it “off” for a predetermined period of time before turning it on again.

A relay could be added to key the transmitter’s PTT circuit every time my CQ message was played. The receiver would automatically listen for any replies between messages. (This might actually work!) [Continue reading…]

Hong Kong Broadcaster’s Swift Turn From Maverick Voice to Official Mouthpiece (NY Times)

RTHK has often set the news agenda with its aggressive coverage of the city. But a Beijing clampdown has changed that, with pro-China coverage filling the void.

HONG KONG — Not long after Patrick Li took over as the government-appointed director of Hong Kong’s public broadcaster, a digital lock pad appeared outside his office entrance.

In the past, the director’s office had been where staffers at the broadcaster, Radio Television Hong Kong, gathered to air grievances with management decisions: programming changes, labor disputes. Now, the lock pad signaled, such complaints were no longer welcome.

For many employees, the closed room was an emblem of the broader transformation sweeping through RTHK, the 93-year-old institution venerated by residents as one of the most trusted news sources in Hong Kong’s once freewheeling media landscape.

RTHK was once compared to the BBC for its fierce editorial independence. But under a sweeping national security law that Beijing imposed last year to silence dissent, many say it now more closely resembles China Central Television, the propagandistic Chinese state broadcaster.[Continue reading…]

‘Gloria’: Netflix’s First Original Series From Portugal Is A Great Spy Thriller (Forbes)

Netflix has released its first Portuguese original series. Glória is on Netflix since November 5. Produced by the SPi production company of Grupo SP Televisão and co-produced with RTP, Glória is an intense historical spy thriller taking place during the Cold War. It is a high-quality series from Portugal with an intricate storyline.

Set in a small Portuguese village named Glória do Ribatejo in the 1960s, the ten-part series follows João Vidal (played by Miguel Nunes), a young man whose family has connections with the leaders of the Estado Novo, the authoritarian Portuguese Regime. João works as an engineer at RARET, a U.S. re-broadcasting office of Radio Free Europe. The series shows how this small village became “an unlikely Cold War stage where American and Soviet forces fought through dangerous sabotage maneuvers to achieve control of Europe,” the Netflix synopsis explains. João gets recruited by the KGB, and will find himself in the middle of the intricate webs of spy games at play in RARET.

An original series created by Pedro Lopes and directed by Tiago Guedes, Glória is a slow-burning series that is a mixture of historical drama based on real events and espionage thriller. The series paints a dark image of Portugal’s past, its violence toward women and its brutal colonial war. It is the highest budget series in the history of Portuguese production, according to The Portugal News. [Continue reading…]

“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.[…]

Switzerland ending RF terrestrial broadcasting of television

Switzerland Is Doing Away With Over-the-Air TV. Could the U.S. Do the Same?

Rabbit ears and other TV antennas could be useless in Switzerland before too long.

The Swiss government has given the country’s public broadcaster approval to turn off its digital terrestrial TV (known as over-the-air to most people) by the end of 2019. It will be the first nation in Europe to do so.

Most Swiss have high speed broadband internet connections and cable networks in their homes, so the move is unlikely to affect many citizens. Only 1.9% of the population, about 64,000 people, reportedly take advantage of the service that’s being discontinued.

Other European nations are expected to follow Switzerland’s lead in the next 10 to 15 years. And while many Americans believe the right to free, over-the-air broadcasts are protected, that’s not quite as cut and dry as it might seem.

Yes, the federal government licenses the airwaves to television stations (among other entities). […]But the government doesn’t license networks, only individual stations, as outlined by the FCC.

“We license only individual broadcast stations,”: the agency says in a 2008 report explaining its authority.

[…]Put another way: Networks are not required to broadcast their shows over the air.[…]

Some scientists believe sun may be crossing into “magnetic middle age”

I just received the following link to a Forbes article from my buddy Charlie (W4MEC).

If this research turns out to be correct–and time will only tell–it could mean very low solar activity from here on out (let’s hope not!):

(Source: Forbes Magazine via Charlie W4MEC)

The Sun has likely already entered into a new unpredicted long-term phase of its evolution as a hydrogen-burning main sequence star — one characterized by magnetic sputtering indicative of a more quiescent middle-age. Or so say the authors of a new paper submitted to The Astrophysical Journal Letters.

Using observations of other sunlike stars made by NASA ’s Kepler Space Telescope, the team found that the Sun is currently in a special phase of its magnetic evolution.

At time of posting (June 28, 2016) the Sun has no Sun spots at all, which means very low solar activity. Credit: SDO/HMI (Click to enlarge)

Heretofore, the Sun was thought to have been just a more slowly rotating version of a normal yellow dwarf (G-spectral type) star. These results offer the first real confirmation that the Sun is in the process of crossing into its magnetic middle age, where its 11-year Sunspot cycles are likely to slowly disappear entirely. That is, from here on out, the Sun is likely to have fewer sunspots than during the first half of its estimated 10 billion year life as a hydrogen-burning star.

“The Sun’s 11-year sunspot cycle is likely to disappear entirely, not just get less pronounced; [since] other stars with similar rotation rates show no sunspot cycles,” Travis Metcalfe, the paper’s lead author and an astronomer at the Space Science Institute in Boulder, Colo., told me.[…]

Forbes: “How To Make Music (And Money) From Shortwave Radio”

3 Replies

Two weeks ago, we posted a video of Evaton Technologies RF Nomad: a modular synthesizer that employs shortwave radio to create unique sounds. As someone who has always been fascinating with music and the sonic texture of the shortwaves, of course I find this product fascinating.

Forbes magazine does too. This morning, @UlisK3LU shared an article in Forbes where Russell Hoffman, who runs Evaton Technologies, explains why he believes using shortwave radio in new RF Nomad will be a hit:

“What’s interesting about shortwave radio is that it isn’t necessarily musical by design, but there are interesting sounds to be found when the station tuning is less than perfect,” he said. “You can hear all sorts of sounds on shortwave, from voice, to music, to Morse Code or encoded digital transmissions. In addition to the sounds that are transmitted intentionally, there are sounds that are artifacts of the medium itself like heterodynes, pops, crackles, hiss, static crashes, fading and the like.”

But here’s my favorite bit:

“Shortwave radio has a long and storied history, full of intrigue, espionage, piracy, rebellion, propaganda, and subterfuge,” he added. “It propagates around the world and can be received on inexpensive equipment. It is universal, because it can be heard anywhere; and yet at the same time, in a world of internet, TV, and satellite radio, it is also the underground — a hidden world parallel to that of our daily experiences. It offers an additional perspective.”

I couldn’t have said it better myself. Thank you, Mr. Hoffman.
