Many thanks to SWLing Post contributor, Ivan Cholakov, who writes:

Thomas, I did not see a story on the blog about the HF atmospheric heating experiments conducted by the Arecibo observatory a couple of weeks ago.

Thomas Cholakov N1SPY made a video about it but I am also sure a bunch of other listeners were able to tune to the super-strong signal on 5125 and 5095 kHz.

Great video, Thomas!

Indeed, I did miss posting this item. The event timing conflicted with my travel schedule in a bad way. Sadly, I only had one opportunity to tune in and I did too late (by just a couple of minutes!) that day.

Did anyone else catch the on-air experiments from Arecibo?

Radio Caroline at 50 years

Radio Caroline circa 1960’s.

Radio Caroline: Golden age of British pirate radio remembered, 50 years on

They were the pirates of the open seas — bringing rock and pop music to a new generation.

And the British government was furious.

Back in the 1960s, when pop and rock were taking over the music scene, British teenagers had to turn to pirate radio stations to hear bands like the Beatles and the Rolling Stones.

Barred from broadcasting from land, stations such as Radio Caroline and Radio London had taken to the water, using rusty old ships moored in international waters to broadcast to millions of eager listeners across the UK.

The government wasn’t happy and 50 years ago, on August 14 1967, the Marine Offences Act made it illegal to support the ships or broadcast from them.[…]

William note that this story can be found on multiple news sources, but the ABC has more photos.

Many thanks for the tips, William! Like many Post readers, I do love Radio Caroline!

Elettra: The story of Guglielmo Marconi through his daughter Princess Elettra Marconi

Many thanks to SWLing Post contributor, William Lee, who notes that the radio documentary Elettra is now available to rent (A$5.10) or download via Vimeo. Note that this program has geographic restrictions and may be limited to streaming in Australia:

ELETTRA from Ronin Films on Vimeo.

Encouraged by her friendship with Australian broadcaster, Ben Starr, the Princess opens her home and her heart to recall and relive her family’s saga.

Her own story is counter-pointed by her memories of her father and all he achieved. As a girl, Elettra watched her father create magic. For her, the use of radio technology to save the?lives of the Titanic survivors and to track down criminals was just part of her father’s wizardry. He had started a revolution. Wireless became the most fabulous invention of the 19th century: the public thought it was miraculous, and leading scientists of the day could not understand how it worked.

Elettra inherited the Marconi empire when she was seven years old. Having spent her life travelling the world to promote her father’s legacy, the Princess now plans to turn her crumbling family palace in Bologna into a radiant academy for the arts and science.
From the gardens of enchanted villas, to the corridors of the Vatican, we peek into the cracks of a new “Dolce Vita”, where nothing is quite what it seems.

For all her joyful enthusiasm, the Princess has found little support for her plan in Italy’s dysfunctional ministries and is searching far beyond. Can she make her dream come true?

Sangean TR-108 iTalker: Ante seeks more information

Sangean TR-108 iTalker

Many thanks to SWLing Post contributor, Ante Milisa, who writes:

I came across a new product from well known radio producer Sangean: the Sangean TR-108.

I believe this is a successor to Sangean’s well-known Sangean PR-D8, which I had and which was great.

The Sangean PR-D8

It seems like this one is currently only produced for the Asian market though. It would be great if they would produce a version for Europe/America as well.

I am sure it would sell well.

Anybody heard anything about this product?

From what I can see, it has FM/AM, radio recording with preset recording, and SD card capability. Everything I need. 🙂

Click here to view details on the Sangean website.

Thanks for your message Ante, especially since I was unfamiliar with either model.

The Sangean PR-D8 had a very unique design with split recording and radio functions on the front panel. Indeed, I don’t think I’ve ever seen anything quite like it. C.Crane sold them, but they now appear to be discontinued. There aren’t any currently on eBay, either (though one did recently sell for $100 shipped).

I read a Google Translate version of the Sangean TR-108 spec sheet. Sadly, I think the TR-108 lacks the AM (mediumwave) band–FM only–so it might not be a direct replacement for the PR-D8. Plus, the TR-108 recording function doesn’t appear to be as full-featured as that of the PR-D8.

Still, I like how the TR-108 buttons appear to have raised, tactile dots for those who are visually-impaired. Looks to be pretty compact as well!

Post readers: please comment if you have more information to share about the Sangean TR-108 iTalker.

Bill to restore shortwave rejected by Senate Committee

A Senate Committee inquiring into the possibility of restoring ABC Shortwave services has rejected proposed legislation to restore the international radio service.

Several members of the committee presented dissenting reports.

The ABC ended its shortwave transmission service in the Northern Territory and to international audiences from 31 January 2017, in line with the national broadcaster’s commitment to dispense with outdated technology and to expand its digital content offerings.

On 16 February 2017, the Senate referred the Australian Broadcasting Corporation Amendment (Restoring Shortwave Radio) Bill 2017 to the Senate Environment and Communications Legislation Committee for inquiry and report in May but an extension of time to report was granted, until yesterday, 9 August.

A close look at the Russian Woodpecker (Duga-3)

3 Replies

(Source: news.com.au via Ian P)

ON MAPS, this site was marked as a children’s playground. That couldn’t be further from the truth.

When the Chernobyl nuclear explosion happened in 1986, it shook the world in many ways. Not only did it put the now ghost town of Pripyat on the map for all the wrong reasons, it also exposed the world to what was really at this site in Ukraine — the dreaded Duga radar, also known as the Russian Woodpecker.

A Soviet engineering and scientific feat of its time, the Russian Woodpecker was an over-the-horizon radar system designed to provide early detection of an intercontinental ballistic missile attack.

[…]Air traffic controls, television and radio broadcasters would be irked by the mysterious pecking noises it emitted, hence its nickname, the Russian Woodpecker.

Built just outside the city of Pripyat, it was completely off limits and unknown to outsiders.
It was erected near Chernobyl due to its high power demands. On maps, it was marked as a summer camp for children hidden in the depths of the forest. Locals were told that the imposing skyscraper was a radio tower.[…]
