Over-the-horizon communication on Mars

ARRL highlights a post by The Space Weather Woman, Dr. Tamitha Skov, that notes the role amateur radio technology could play in over-the-horizon radio communications on Mars

I am still smiling at the huge response I got to a post I put up on Twitter this week. A newbie to our Space Weather community dared to talk about Amateur Radio as if it were an outdated hobby– whoops, bad idea. I gently educated him.
In doing so, I roused many radio amateurs and emergency communicators, who added their own comments and talked about their own personal experiences in the field. It was very gratifying.

What I hadn’t expected, however, was the strong interest in the concept that amateur radio will be critical to establishing over-the-horizon radio communications on planets like Mars in the near future.

This idea brings me back to how we managed to communicate over long distances many decades before we had satellites, internet or cellular networks. In terms of wireless communications on Earth, we were very much in the same place back in the early 1900s that we find ourselves in now when we think about colonizing Mars.
Yet few people realize that despite all our advanced technology, we can’t bring a cell phone to Mars. We will need to fall back on our ‘old ways’ of doing things when it comes to communicating on other planets. Isn’t it funny how ‘old’ things become ‘new’ again?

Bruce discovers a bit of Morse Code in “Picnic At Hanging Rock”

(Image source: IMDB)

Many thanks to SWLing Post contributor, Bruce Fisher, who writes:

I recorded this short piece of the soundtrack from the 3rd episode of the Picnic at Hanging Rock mini series– it’s being used as a part of the music to an eerie scene, and there is no telegraph or radio related visual corresponding to it. It certainly sounds like Morse Code to me, but I haven’t decoded it. Anyone?

(If you can’t see the embedded player above, click here to listen.)

Many thanks, Bruce! You certainly have sharp ears and are correct in assuming this is Morse Code. The spacing and cadence are a little awkward and jittery, however. I did a decode myself, but I’m curious what others might have heard.

Post readers: Please comment with what you heard in this code!

Raspberry Pi Vintage Radio

This project was a winner in the Maker Share Mission May contest. While not strictly shortwave, of course, many of SWLing Blog readers enjoy, as I do, all things radio, and especially creative and new expressions of radio. Here is a brief excerpt from the MakerShare posting:

Vintage radios are fascinating. At one point the radio was the main method for mass communication of news and entertainment and was manufactured in a variety of styles to be prominently displayed in a home. Unfortunately, many vintage radios that have been physically preserved no longer function and it is impractical for them to be repaired. Described is the design and implementation of the Raspberry Pi Radio (RPiRadio), a device that bypasses the analog electronics of a vintage radio and digitally recreates the behavior of a vintage radio that is able to be tuned to vintage radio programming.

The whole posting may be found here, with extensive details on the building of the radio and how it was programmed for sound replicating the vintage radio era.

While I love tinkering with old radios and trying to bring them back to life, some radios are just beyond reasonable repair. This can bring old radios back to life in a way which seeks to honor their past – a very cool idea indeed!

Internet Radio and Global Time Travel

Many thanks to SWLing Post contributor, Kim Elliott, who shares this brilliant article from The Paris Review:

On The Radio, It’s Always Midnight

By Seb Emina

“Ultimately, we don’t belong in the world governed by time,” says Michael Cremo, a guest on KNWZ, a radio station in Palm Springs, California. “As beings of pure consciousness, we are essentially timeless.” It is around two thirty A.M. in Palm Springs and around eleven thirty A.M. in Paris, where I am tidying my apartment. Cremo is talking about the end-time, which he thinks could well be imminent, but his point is relevant to the experience of listening to local radio from somewhere I am not. I love listening to radio, but sometimes I don’t want to listen to a particular station, genre, or category. Sometimes I want to listen to a time of day. Which is, of course, entirely possible thanks to the rise of online streaming at the expense of older analogue broadcast methods. If I am feeling afternoony in the morning, I can leave the world that is “governed by time” and join whichever community of radio listeners—in Mumbai, Perth, or Hong Kong—is currently experiencing three P.M. The optimism of a morning show somewhere to my west offers a fresh beginning to a day that’s become lousy by midafternoon, whereas the broadcasts of early evening, burbling across the towns and cities to my east, can turn my morning shower into a kind of short-haul time machine past those hours in which I’m expected to be productive. But for the loosest and strangest of broadcast atmospheres, I am drawn most often to the dead of night, to the so-called graveyard shift. That low-budget menagerie of voices and music is concocted to serve an unlikely fellowship of insomniacs, police officers, teenagers, and bakers—and cheats like me, tuning in from afar to behold radio’s closest equivalent to the Arctic Circle.

“When you listen to radio, you are a witness of the everlasting war between idea and appearance, between time and eternity, between the human and the divine,” Herman Hesse writes.[…]

It’s rare that I read something in the press that so directly speaks to my own personal relationship with radio.

While, of course, I still prefer listening to shortwave radio, international broadcasts are designed with a global audience in mind; in a sense, they’re timeless and gloss over our global time zones.

Internet radio streaming brings in the local and actually provides more community context. And, of course, while a country might only have one international broadcaster, it could literally have hundreds of local stations–some catering to very small communities.

I’m certainly guilty of time zone surfing with WiFi/Internet radio, I just didn’t realize others did it too! Even in the mornings (since the demise of my shortwave staple Radio Australia), I typically listen to CBC St. John’s, Newfoundland. They’ve got an excellent morning show and they’re 1.5 hours ahead of my time. When I wake at 5:00 AM, I listen to the world report and the CBC local staff are pulling out some of their best morning programs.

Then anytime between 3:00 or 6:00 PM, I’ll tune through one of a number of New Zealand or Australian stations. Because it’s morning there, the presenters seem to have a spring in their step.

If you read the full article in The Paris Review, you’ll also note that the author Seb Emina and the artist Daniel John Jones created “a perpetual morning-radio aggregator” called Global Breakfast Radio.

You can stream Global Breakfast Radio at globalbreakfastradio.com. I highly recommend it!

School of the Air celebrates 60 years and a vision of independence

(Source: ABC News vi Kim Elliott)

Parents of children in South Australia’s outback are calling for the state’s School of the Air to become independent so it has more control over how students learn.

The school at Port Augusta in the state’s north has marked its 60th anniversary of delivering lessons to students in remote areas.

When the school began in 1958, lessons were given via high frequency (HF) radio, but are now done over the internet.

In 1991, the School of the Air amalgamated with the SA Correspondence School to become Open Access College, which is based in Adelaide.

At a recent meeting in Port Augusta, the Isolated Children’s Parents’ Association called for the School of the Air to become an autonomous education provider.

The association’s north-west branch president Lynly Kerin said it was “no longer beneficial or manageable” for the school to be part of the college, and that its 49 students were being overlooked in the college’s cohort of 5,600 students.

Ms Kerin said the School of the Air community felt “overshadowed by decisions being made by people who may not understand the needs of our kids out here in remote areas”.

“At the very least, we request that the Minister look at an investigation into the change that we’re proposing,” she said.[…]
