Radio Waves: First Microprocessors, Ocean FM, SWL Interviews, and NPR’s take on All-Digital AM

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’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Marty, Martin Butera, and the Radio Survivor for the following tips:

The Surprising Story of the First Microprocessors (IEEE Spectrum)

Transistors, the electronic amplifiers and switches found at the heart of everything from pocket radios to warehouse-size supercomputers, were invented in 1947. Early devices were of a type called bipolar transistors, which are still in use. By the 1960s, engineers had figured out how to combine multiple bipolar transistors into single integrated circuits. But because of the complex structure of these transistors, an integrated circuit could contain only a small number of them. So although a minicomputer built from bipolar integrated circuits was much smaller than earlier computers, it still required multiple boards with hundreds of chips.[]

Ocean FM Was Fire: How Local Radio Done Right Can Heat A Cabin | Radio Schmaltz (Part-Time Audiofile)

[…]The cabin on a rocky peninsula in Northwest Ireland might not have had all the letters for its Scrabble set or a microwave, but it did have another marvel of 20th century technology. It was a little CB/AM/FM radio crouching behind a box of matches on top of a kitchen cabinet.

I decided to put the switch on FM and started swirling the dial. As soon as I heard a lilting woman’s voice underneath a sheet of static, I began carrying it around the tiny room while adjusting the rabbit ears.

Now the signal was as clear as the peat-rich water was brown, a farmer was being interviewed about the economic downturn. It was a quick piece — just some brogue-ish assurances that one doesn’t choose agriculture for an easy life. Then came a trio playing an Irish ballad, and then came North West Hospice Bingo: a bingo game that allows listeners from across the broadcast range of Ocean FM’s two regional frequencies to play bingo, including the residents of the hospice.

I’d bundle up for walks outside where the wind was loud, blustery, and sacred. The ocean crashed against the rocks in a way I never conceived as being real outside of movies. But when I was inside, the radio might as well have been a Soviet relic with only a volume control and no tuner because I simply couldn’t touch that dial. I learned the schedule quickly, timing walks and firewood runs so that I’d be back in time for Country Jamboree, a boy-girl-boy-girl style line-up of Irish and American country tunes.

As I’d stand by the wood-stove, taking off my cold wet socks to put on the toasted, at time singed socks that I’d been roasting, I felt the fulfillment of the promise of radio. I could hear Fessenden making history with the first radio broadcast of music, Oh Holy Night transmitted on a rocky coast on Christmas Eve of 1906 and heard by ships at sea.[]

Coffee and Radio Listen

Coffee and Radio Listen is an investigation of Brazilian radio listener, by Martin Butera.

How they began listening to radio, the local or international stations that influenced them, the interests they have when tuning to a station, the languages they like to listen to, if they send listeners reports and collect QSLs, their antennas and receivers, and all aspects related to the radio listen both in shortwave and in other bands and modes.

Each month they will have in this blog, an exclusive interview with a Brazilian radio listen. At the end of this project, a free downloadable e-book will be available, which contains all the interviews and statistical references.

Every month there will be a new interview, this month of March launch month we start with 2 interviews

Martin is Argentinian, born in the city of Buenos Aires capital. He currently lives in Brasília DF, capital of Brazil. He is also a journalist, documentary maker and founding member of Radio Atomika 106.1 MHz (Buenos Aires, Argentina).

NPR Supports All-Digital on AM, With Caveats (Radio World)

National Public Radio “generally supports” allowing stations to transition, if they wish, to all-digital AM transmission using HD Radio in the United States. But it believes the commission needs to go further on how it would handle interference complaints from neighboring analog stations in the band.

About 80 AM public radio stations are affiliated with NPR or receive operational funding from the Corporation for Public Broadcasting, including WNYC(AM) in New York City.

NPR says it has significant interest in any measures to help AM broadcasters better serve the public by improving the listening experience.

“Facilitating the expansion of HD Radio and its additional functionality for program and public safety information and services would serve the public interest, provided the transition to all-digital HD Radio operation does not cause harmful interference,” NPR wrote in comments filed with the FCC this week.

“As it has in the past, NPR supports the expansion of HD Radio, but not at the expense of current analog AM service.”[…]

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’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Here’s the first Radio Waves story collection. Enjoy!

‘The Culling Has Begun’: Inside the iHeartMedia Layoffs (Rolling Stone)

The largest radio company in America cut a number of employees this week, dealing a blow to local radio across the country

“The largest radio conglomerate in the country, iHeartMedia, initiated a round of mass layoffs this week, cutting enough people that one former on-air host described Tuesday as “one of the worst days in on-air radio history.” The layoffs were concentrated in small and medium markets, where staffs had already been reduced, striking another major blow to local radio.”

AER (Asociación Española de Radioescucha) Radio JK FM

SWLing Post contributor, Martin Butera, writes:

“Proclaimed in 2011 by UNESCO member states, and adopted by the United Nations General Assembly in 2012 as International Day, February 13 became World Radio Day (WRD). This 2020, on World Radio Day, UNESCO calls on all radio stations to defend diversity, both in their newsrooms and on radio waves. Martin Butera, visited an important FM of Brasilia DF, capital of Brazil and anticipates this year’s motto that will be: “Pluralism, representation and diversity.”

Give radio pirates chance to go legit (The Boston Globe)

The massive fines levied last month against two unlicensed Boston stations that served the Haitian immigrant community went too far.

The Invisible War of the Cold War Airwaves (X-Ray Audio)

In the radio show below, an episode of our Bureau of Lost Culture series on Soho Radio, we meet with Russian journalist, broadcaster and writer Vladimir Raevsky to hear the fascinating story of the Soviet Radio Jammers. Vladimir tells of the extraordinary lengths people went to to listen to the music they loved and of the gigantic amount of money spent by both sides in this invisible war of the airwaves.

We also hear from BBC Russian Arts correspondent Alex Kan about the brave / foolhardy so-called Radio Hooligans – the technically savvy young Soviets who dared to risk punishment by setting up their own little pirate radio stations to broadcast themselves and the music they liked using bootlegged and adapted equipment.

And finally we hear the strange story of the signal emitted by The Duga a gigantic mysterious installation near the Chernobyl nuclear site.

Many thanks to SWLing Post contributor Martin Butera, founding member of the 15.61 Crew, for the following guest post:


The 15.61 Crew Radio Listeners, Martin Butera and Ivan Dias, give us a small video preview made in the first Dx-Camp on Marajó Island in the Amazon Rainforest, North of Brazil on November 2019.

There are more than 11 hours of SDR recordings and videos of the Ultralight radios, which will take much additional time to process, of course.

Crew is working on the report with a complete story that includes videos and photos of everything experienced during the DX-Camp–this will be published in several languages and the first LOG, which we estimate will be the first months of the South American summer 2020.

We recommend not forgetting to periodically visit the official site of the DX-Camp, to find updated information: https://dxcamp-marajo2019.blogspot.com/

Above, you’ll see a short stretch of the medium wave band with plenty of interesting content: 585 kHz, alternating between National Radio of Spain (Madrid), BSKSA (Saudi Arabia), 590 kHz, alternating with Poty Radio (Crateús / CE), Radio Diffuser (Boa Vista / RR) and Radio Continental (Buenos Aires), 594 kHz BSKSA (Saudi Arabia), 595.9 kHz SNRT (Morocco – operating off-frequency for years), 600 kHz Mirante Radio (São Luís / MA), Vale Radio (Barreiras) / BA) and Radio Gaucha (Porto Alegre / RS) and 603 kHz National Radio of Spain (Sevilla).

Videos

All of the following videos were captured during the November 2019 Dx-Camp:


Brazil is a country with vast continental distances. The following three videos showcase Brazilian radio from across the country.

Radio Diffuser Boa Vista (1408 km distance)

Radio Itatiaia 2191 (km distance)

Radio Band B (2747 km distance)

Dx-Camp Marajó Island: A small action to change our world

Many thanks to SWLing Post contributor Martin Butera who shares the following note:

A small action to change our world.

Fulfilling our commitment to get involved in causes of direct action, instead of only DX we decided to do something.

For this reason we planted in the Marajó island a small tree in the name of the European DX Council (EDXC) which we affectionately baptized with the name “Chrissy”, referring to our friend Chrissy Brand, Chief Editor of BDXC bulletin and European DX Council (EDXC) Secretary, who supported this DXcamp.

We are aware that planting a tree in the midst of the flames that are killing the Amazon rainforest will not be its salvation, but will leave a legacy and is a way to contribute to a better world.

Help the environment does not require big actions, but small ones, such as:

  • Separate out our waste for later recycling;
  • Turn off the lights. It seems obvious, but we don’t realize how many times we turn on the light of a room we will not stay in;
  • Eat organic fruits and vegetables. Organic products help the environment because in their production no fertilizers or other polluting products are needed;
  • Turn off the faucet correctly. When you do not need water, turn off the faucet and check for leaks;
  • Go by bicycle or public transport. Pollution in big cities comes largely from the excessive use of cars;
  • Take your own bags to the supermarket. More and more supermarkets are selling plastic bags to avoid their use and encourage recycling;
  • Take advantage of natural light. To reduce the electricity consumption, open the windows and curtains so that sunlight enters your home;
  • Recycle everything you can. Before throwing clothes, books or toys, think about whether you can give them a second chance to avoid spending and buying everything new. You will save money and protect the environment.

As you could read, they are small actions that help energy saving, recycling and conservation of these resources.

The report will be ready in January 2020,
Stay tuned for the official website https://dxcamp-marajo2019.blogspot.com/ and for the publications of SWLing Post and the BDXC (British Dx Club).

Crew 15.61 announces its first DXcamp in the Amazon rainforest

Crew 15.61 announces its first DXcamp in the Amazon rainforest of Brazil and launches its exclusive event site.


From today you can visit https://dxcamp-marajo2019.blogspot.com/ and find all the information about the first DXcamps of the 15.61 Crew.

The DXcamp, will be held between November 15-18 on Marajó island. It’s the first time that an event with these dimensions and characteristics is held in Brazil and maybe in South America.

This DXcamp got the attention of several sponsors who helped the 15.61 Crew, including: C.Crane, SDRplay, DS Antennas (Brazil), Heil Sound, COMPACtenna, Cross Country Wireless, Antennas4Less, NI4L Antennas, Radiwow, RTL-SDR, ELAD, SSB, RadioShack, Antennas Loop DZ by Denis Zoqbi (Brazil), Arrow Antennas and the SWLing Post blog.

“When the Last Tree Is Cut Down, the Last Fish Eaten, and the Last Stream Poisoned, You Will Realize That You Cannot Eat Money ” (Native American saying).

Vital to the planet weather, the Amazon region has suffered fires for several weeks and several organizations have denounced the silence of Brazilian President Jair Bolsonaro about what they consider a devastating environmental crime against Earth. Such disaster has caused worldwide shock and must be remembered, because as something that happened during September, unfortunately the media coverage is focusing probably another disaster.

Marajó is the largest island in Brazil and the largest river island in the world, where the Amazon and Tocantins rivers and the Atlantic Ocean meet. It’s located about three hours by boat from Belém, capital of Pará state.

The 15.61 Crew founders are Martín Butera, correspondent journalist in South America for the British DX Club and Ivan Dias da Silva Júnior, founder of the Regional DX group of Sorocaba/São Paulo.

The objective of 15.61 Crew is not just DX. We will take a direct and committed action to help the planet and raise awareness about the climate change that we are sadly living.

We will plant a tree on behalf of the European DX Council (EDXC). Planting a tree amid the flames that are killing the Amazon rainforest today will certainly not be your salvation, but it will leave a legacy and our contribution for a better world.

We will raise awareness that together we can change this situation with actions such like waste sorting, buying products that can be reused, lowering electricity consumption, eating more organic fruits and vegetables, moving on public transport and so on.

Martin Butera lives in Brasilia, the capital of Brazil, about 27 hours from Belém or 1982 km. Ivan, lives in Sorocaba,São Paulo state, 38 hours from Belém or 2893 km. Both will meet in Belém and then go by boat to the island.

A trip like this requires a lot of preparation. It’s not something cheap or easy to be done. It takes a lot of time, effort and personal expenses to go to these remote places in South America and then share our catches with you. Those who would like to collaborate with us can do by Paypal account, from our website.

Why do we ask your financial support? Airline weight limits and luggage size are a problem in South America and are increasing the costs for us. We also have a long boat trip of more than 3 hours and will rent a house in the island.

Everything is already paid, but your help can made everything easier on the next DXcamps of 15.61 Crew. All donations will be reported on our site, but whoever makes an anonymous donation will be kept anonymous, and we will report only the value. Please consider support our DXcamp camp in Marajó island!

Your contribution will help us take the best listening station we can gather and have more and better chances of getting good results.

The 15.61 Crew founders, have extensive experience in the hobby, both Martin, 29 years as a ham radio operator (LU9EFO-PT2ZDX), with many DXpeditions in several South American islands, as Ivan, started DXing 26 years ago, including contributions to several clubs and as utility stations professional monitor.

Everything we do during this DXcamp will be shared by texts, photos and videos of our correspondent Martín Butera and will be published as son as possible on the BDXC bulletin and SWLing Post blog.

This will be the first of many DXcamps in exotic places that we plan to carry out, always with a message and a proposal for direct action. We are living in a world in danger and our roles as a society can’t be limited only to be only radio listeners.

Thank you!
