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.[…]

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 Dennis Dura, Mike Terry and the International Radio Report for the following tips:
Streaming means we can tune into breakfast shows, travel bulletins and local gossip on every continent – and revel in radio’s ability to create a sense of community
I’d missed the joke about the three-legged chicken. It was causing a stir.
“That one about the chicken with three legs you told yesterday,” said a presenter on Ireland’s Midwest Radio’s afternoon show, “apparently Ronald Reagan told it first.”
“Did he, now?” the co-host replied.
“Yes. You stole a joke from Ronald Reagan.”
Jeez, I’m going as red as a tomato here.”
The conjunction of tripedal fowl, the 40th president of the United States and two men in a studio in Ballyhaunis, County Mayo, will never make a list of great radio moments but it was enough to coax me from between my four walls, even if it was via the imagination.
Radio has never been more popular: it’s seen off challenges, from television to the internet, to become stronger than ever. In 2017, according to industry ratings body Rajar, nine out of 10 people in the UK listened to the radio every week. Perhaps it succeeds because we have to conjure up our own pictures of events and places beyond our immediate surroundings. As a bored, lonely boy growing up in an anonymous south-east London suburb, I’d spend most evenings in my bedroom jamming a coathanger into the back of an old radio and scanning the airwaves, awestruck by the range of languages and music bursting out of the night through skirling static; each voice sending tantalising reassurance of a world beyond the dispiriting confines of my own.[…]
With the passing of Ronan O’Rahilly in April 2020, a colossus of radio broadcasting has left a legacy that will stand the test of time and has made a massive impression on radio broadcasting in Ireland. While his beloved Radio Caroline was a familiar sight off the South East of England, its influence on both radio and music in 1960’s Britain cannot be underestimated. It forced the British Government to enact new legislation outlawing the almost a dozen pirate radio ships that blasted pop music into Britain and it forced the BBC to reorganise and compete with the opening of a dedicated pop channel in 1967, BBC Radio One. In the month when Ronan passed onto the afterlife, both BBC Radio One and Radio Caroline still broadcast today. But while Caroline’s history focusses mainly on its influence on Britain, Ireland has played a key role in that colourful history and this is that story.
At the helm of Radio Caroline was Ronan O’Rahilly. He was born in Clondalkin, Dublin in 1940, his father Aodogan was a well-known and wealthy businessman, regarded as an influential ally of Eamon DeValera, while his grandfather Michael O’Rahilly was better known as The O’Rahilly, sacrificed his life during the 1916 Easter Rising having been shot dead while leading a charge on a British position at the end of Moore Street.[…]
ARISS News Release No. 20-03
April 28, 2020 —Amateur Radio on the International Space Station (ARISS) is pleased to announce the first use of a concept called Multipoint Telebridge Contact via Amateur Radio, allowing school contacts for Stay-At-Home students and simultaneous reception by families, school faculty and the public.
During the last several weeks, efforts to contain the spread of the COVID-19 virus have resulted in massive school closures worldwide. In addition, the Stay-At-Home policies invoked by authorities, initially shut down opportunities for ARISS school contacts for the near future.
To circumvent these challenges and keep students and the public safe, ARISS is introducing the Multipoint Telebridge Contact via Amateur Radio concept. First operation of this experimental system will occur during a contact scheduled with a group of Northern Virginia Students located in Woodbridge, VA on Thursday, April 30 at 13:35 UTC (9:35 EDT). During this event, an ARISS telebridge radio ground station will link to the astronaut on the International Space Station (ISS) ham radio station and each Stay-At-Home student and their teacher will be individually linked to the telebridge station. Under the teacher’s direction, each student, from their home, takes a turn asking their question of the astronaut.
Quoting ARISS Chair Frank Bauer, “This approach is a huge pivot for ARISS, but we feel it is a great strategic move for ARISS. In these times of isolation due to the virus, these ARISS connections provide a fantastic psychological boost to students, families, educators and the public. And they continue our long-standing efforts to inspire, engage and educate student in STEAM subjects and encourage them to pursue STEAM careers.”
During the contact, participants will ask as many of the following questions as time allows:
1. What does the sun look like from outer space?
2. How comfortable is it to sleep in space?
3. What is one thing you want to eat when you get back to earth?
4. I’ve heard that stars are red, yellow and blue. Can you see those colors in space when you look at the stars?
5. Besides your family, what do you miss most while being in space?
6. What are your thoughts on our Covid-19 situation right now? Does the Earth look differently over the last 3 months now that many people are inside and not creating pollution?
7. How often do you get to go out of the ISS? Have you been on any space walks?
8. Who makes the rocket that takes you to the ISS?
9. What does it feel like to float all the time?
10. Do you use flashlights on space walks?
11. How do you exercise in space?
12. How do you get out for space walks safely without the air from the ISS coming out into space? How does it feel to walk in space?
13. What do you wear in the space station?
14. How did it feel when you first got to space?
15. How is space different from Earth?
16. What do you study in school to become an astronaut?
17. What do you like the most about being in space?
18. Were you nervous when you launched into space?
19. How do you communicate with loved ones while you are in space?
Many thanks to SWLing Post contributors David and Monti who share a link to Radio Garden, a new web-based interface for exploring online radio stations across the globe.
[…]Radio Garden, which launched today, is a similar concept—a way to know humanity through its sounds, through its music. It’s an interactive map that lets you tune into any one of thousands of radio stations all over the world in real time. Exploring the site is both immersive and a bit disorienting—it offers the sense of lurking near Earth as an outsider. In an instant, you can click to any dot on the map and hear what’s playing on the radio there, from Miami to Lahore to Berlin to Sulaymaniyah and beyond.
The project, created for the Netherlands Institute for Sound and Vision by the interactive design firms Studio Puckey and Moniker, was built using an open-source WebGL globe that draws from thousands of radio stations—terrestrial and online-only streams—overlaid with Bing satellite imagery.
The result is the best kind of internet rabbit hole: Engrossing, perspective shifting, provocative, and delightful. […]
