BBC Crowd Science: “How does my radio work?”

Many thanks to SWLing Post contributor, Kris Partridge, for sharing the following story:

Crowd Science: How does my radio work?

How is a small budget pocket radio able to recreate all the atmosphere and sounds of a football match? CrowdScience listener Andy wants to know about the science enabling his radio listening, so presenter CrowdScience Geoff Marsh sets off – microphone in hand – to follow the journey of sound on the radio.

Starting with the microphone, Geoff learns how acoustic energy is converted into electrical signals. Then BBC World Service presenter Gareth takes Geoff to a little-known room in the BBC called the Radio Shack. Gareth demonstrates how these electrical signals are attached to radio waves before being sent over the airwaves and they take a radio kit apart to understand how these waves are received and converted back into sound waves.
Geoff talks to a speech and hearing specialist who, through the use of auditory illusions, shows Geoff that our brains are often filling in the gaps of lower quality audio.

Finally, Geoff visits an acoustic lab at Salford University where he hears a demonstration of ‘object based audio’. This technology could enable us to create our own bespoke mix of dramas and sports, such as heightening the commentary sound or choosing to hear just the crowd, just by using the everyday speakers many have lying around them, such as mobile phones.

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!

Experimental Radio News 3 (Experimental Radio)

This issue concerns High-Frequency Trading (HFT) transmissions, and three prospective stations seeking entry into the International Broadcast service.

Several stations licensed in the Experimental Radio Service (ERS) transmit data for automated trading to foreign exchanges in the shortwave or high-frequency (HF, 3-30 MHz) spectrum.

High-Frequency Trading (HFT) is a form of automated trading that employs low-latency, high-speed telecommunications to minimize response times. The term is not related to the shortwave or HF spectrum, but this article concerns transmission of HFT messages on HF frequencies.

HF signals can traverse great distances by refraction from ionized layers of the atmosphere, a phenomenon known as ionospheric propagation. Several ERS HFT stations have operated in the HF bands for years out of the public view. Bob Van Valzah blogged extensively about these stations starting in 2018.

These ERS stations’ licenses are public records, but the licensees typically ask the FCC to withhold access to station details and experimental plans. The Commission’s routine acceptance of these confidentiality requests makes public oversight difficult. [Continue reading at Experimental Radio…]

Radio Bulgaria back on shortwave

Many thanks to SWLing Post contributor, Richard Langley, who writes:

As I reported to Glenn Hauser’s group today, Bulgarian National Radio’s Radio Bulgaria is back on shortwave.

Their weekday roughly 22-minute podcast in English, called “Bulgaria Today,” is being aired by ShortwaveService from Kall, Germany, on 3985 kHz from 18:30 until about 18:52 UTC.

Today (30 January), the podcast dated Thursday, 27 January, was broadcast. The program consisted of news, COVID-19 information, weather, travel, and the “Music Slot.” Reception using the U. Twente SDR receiver was fairly good.

There is also a German broadcast before the English one beginning at 18:00 UTC. The ShortwaveService tuning signal is used to fill out the half-hour slot in each case.

All the best

Howard Hesseman, who played Johnny Fever on ‘WKRP in Cincinnati,’ dies at 81 (NPR)

NEW YORK — Howard Hesseman, who played the radio disc jockey Johnny Fever on the sitcom “WKRP in Cincinnati” and the actor-turned-history teacher Charlie Moore on “Head of the Class,” has died. He was 81.

Hesseman died Saturday in Los Angeles due to complications from colon surgery, his manager Robbie Kass said Sunday.

Hesseman, who had himself been a radio DJ in the ’60s, earned two Emmy nominations for playing Johnny Fever on CBS’ “WKRP in Cincinnati,” which ran for four seasons from 1978-1982. The role made Hesseman a counterculture icon at a time when few hippie characters made it onto network television. [Continue reading…]

Radio Waves: Stories Making Waves in the World of Radio

GPS Tutorial by Bartosz Ciechanowski

Check out this amazing, dynamic deep-dive into the world of GPS.

The BBC’s First Female Employee: Isobel Shields (The British Broadcasting Century with Paul Kerensa)

Episode 41 (aka Season 3 episode 2):

On January 2nd 1923, John Reith interviewed Miss Frances Isobel Shields for a job at the BBC, to be his secretary. At the time the BBC had four or five male staff members. Miss Shields started work on January 8th, instantly making the BBC a 20% female organisation. It’s been greater than that ever since.

This episode’s fab guest is Dr Kate Murphy: academic, former producer of BBC’s Woman’s Hour and author of Behind the Wireless: A History of Early Women at the BBC. Her book is brilliant and highly recommended for a deep dive into the subject.

Hear Isobel Shields’ tale, plus the women who broadcast before her: Britain’s first DJ Gertrude Donisthorpe, 2LO’s first children’s presenter Vivienne Chatterton, and one of our first broadcast comedians Helena Millais. (You can hear their fuller tales if you go back to the earlier episodes on this podcast.)

And hear about some of the women who joined the BBC soon after Miss Shields, like telephonist Olive May and women’s staff supervisor Caroline Banks. Plus hear about some of John Reith’s unusual management practices, from taking his secretaries to the cinema to his brutal firing criteria.

But we dwell on his hiring not firing, as well tell the origin story of British broadcasting. [Continue reading…]

Hidden Morse Code in Tubular Bells (Madpsy’s Palace)

The link between The Exorcist, Amateur Radio and Alan Turing.

A quick look at how the movie The Exorcist from 1973 has links to the late great Alan Turing via Mike Oldfield’s album Tubular Bells, Scotland and Amateur Radio. It’s Halloween so figured why not throw some horror in the mix.

When Mike Oldfield recorded Tubular Bells in 1973 he had no idea his first album on Virgin Records would be chosen as the soundtrack to The Exorcist later that year. Neither did he know that recording with Virgin Records would have an unintended consequence of hiding a secret message which dates back to 1926, shortly after World War One.

Tubular Bells was famously recorded at The Manor Studio which was owned by Richard Branston and used as a recording studio for Virgin Records. The building is located in Shipton-on-Cherwell, England. Mike was given one week to record the album, on which he played almost all the instruments himself.

The album initially struggled to sell. Then, later the same year, it was chosen as the soundtrack for the movie The Exorcist. It then experienced massive success and has since sold over 15 million copies worldwide. [Continue reading…]

Mystery radio in “Orphan Black”

14 Replies

Many thanks to SWLing Post contributor, Alan Lurie, who writes:

Hey, I’ve known your site for quite a while, ever since someone gave me Sony’s last portable world band radio, the ICF-SW7600 many years ago. Was wondering if maybe you or someone else who peruses your blog would recognize this set in the background of an episode of Orphan Black.

Hard to tell, but it appears to be a more conventional radio. Regardless, it is positively fierce! And since the imrdb seems to have died, I thought I’d ask you. Hope it’s not a bother. I’m still learning so please keep up the good work!

Alan

It’s not a bother at all, Alan! Indeed, many here in the SWLing Post community love solving our radio mysteries. Sadly, I can’t get enough detail from the image to determine the model, but I’m willing to bet someone else can! There are a couple good clues in there.

Readers: Please comment if you can ID this radio. Good luck!

Raspberry and internet radio

by Pavel Kraus

Raspberry and Volumio

I recently read an article about a Raspberry microcomputer here and I would like to introduce you to an idea that is easy to implement, not too expensive and does not require special computer knowledge due to the number of detailed instructions on the Internet. With Raspberry and the Volumio free software audiophile system, it is possible to design devices that allow you to play music files from connected or network storage or listen to Internet radio, etc. You can also play music from Spotify using the available plugins.

The system can be controlled by touch from the built-in display, from a mobile phone or tablet or by remote control. There are a huge number of internet radios, you can search them by genre or by country. For example, radio stations in the United States are categorized by state, in each state by city, and we can select individual stations in that city.

Volumio is the name for the project, which is presented at https://volumio.com/en/.

There is also the option to download this software and install it on a microSD card. Detailed documentation is available at https://volumio.github.io/docs/, so I will not describe it in detail here, the installation itself is not complicated. I used the following components to make this device: Continue reading →

Guest Post: Mark explores a 1983 Voice of America information pack

Many thanks to SWLing Post contributor, Mark Hirst, who shares the following guest post:

VOA Information Pack 1983

by Mark Hirst

Introduction

A recent guest post on this blog by Jock Elliott asked the question, ‘Why Listen to Shortwave?’

The comment I left at the time was my interest in how nations view themselves, and how they project that view to the world. This might be in the form of cultural exports like music, or teaching us about famous people or revered institutions in their country.

When I first started listening to shortwave in the early eighties, I never got into the habit of asking for QSL cards, being quite thrilled enough to receive programme guides in envelopes stamped with the postmark of other countries.

At the time, the primary stations for me included Radio Netherlands, Radio Sweden, Swiss Radio International, and the Voice of America. While most might send a small leaflet about their country with a frequency schedule, the information pack I received from the Voice of America stands head and shoulders above the others.

I thought readers might be interested in a brief description of this pack and with it a glimpse back into the world of 1983.

Please note that as you read the following sections, you can click on the images to view a larger version.

Package Contents

The package arrived in a manila envelope, with the logo and address of the VOA printed in the top left corner. In the top right corner is the logo of US Mail, with a declaration that postage and fees where paid for by the US Information Agency.
