Radio Caroline at 50 years

Radio Caroline circa 1960’s.

Many thanks to SWLing Post contributor, William Lee, who shares this item from ABC News:

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.[…]

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?

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

(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.[…]

Seventy years ago, Thor Heyerdahl packed a National NC-173 and made history

The National NC-173

Many thanks to SWLing Post contributor, Kris Partridge (G8AUU), who sent the following feedback a few days ago. Sorry for missing the boat, Kris!

Kris writes:

Just under two weeks ago I was watching a Norwegian film on Polish TV (no, don’t ask) and knowing how the sight of old radio’s in films is of interest to you and your readers I was going to write but travel and work, Passendale100 commemorations in Belgium, got in the way. The radio in question was a National NC-173 receiver. And the film Kon-Tiki.

There is much written about the exploits of the voyage and the operators of LI2B. I give as an example from PA7MDJ http://pa7mdj.blogspot.co.uk/2016/10/the-kon-tiki-expedition-and-heroes-of.html?m=1 I leave it to PA7MDJ’s most excellent blog to tell more, he has some Nation Radio Company images from 1947 illustrating his piece and at the end there is a very extensive links listing.

But another reason for writing is that tomorrow, Monday, 07 August is the 70th anniversary of the end of the voyage as the raft landed on the reef. On the 67th anniversary the ARRL did an article on LI2B, why the 67th?

What happened on the 7th of August 1947, and in the 36 hours after, says much about the build quality of the National NC-173.

How many radios today would survive a dunking in seawater and after drying out still be working?

I’ve just been to my book shelves and after a small search found my copy of The Kon-Tiki Expedition published in 1950 given to me not too many years later.

You find LI2B in the book’s index twice. Once describing the operation of the radio ‘corner’ and a very QRP contact between the raft and Oslo Norway. 6 watts CW on 13990 kc. per second, the book being written in 1949 no kHz.

LI2B had been given permission to operate out of but adjacent to as well as in the 20 metre band. The second entry concerns what happen after the raft ends up on the reef and the radio shack and equipment got flooded.

They had been in contact before hitting the reef and there was a 36 hour window before the air search and rescue operations would begin. The drying out of the equipment took no little time and the writer describes how slowly the receiver came to life but no transmitter.

Finally they were able make contact, just before the 36 hrs ended,using a WW2 hand cranked resistance, the book says sabotage, transmitter.

Both the radio operators on the Kon-Tiki had been radio operators in the Norwegian resistance in WW2, only 2 years earlier.

If one puts LI2B into Google images quite an interesting assortment of radio related images are found (click here to view search), including QSL cards but the one I like best is this http://f6blk.net/photos/LI2Bshack_x1.jpg:

I’m sure I’ve seen an English language version, this one looks slightly cropped since the end of the ‘Earth’ wire is out of vision

How fascinating! Thanks so much for sharing this, Kris.

Again, apologies I didn’t get this posted prior to the 70th anniversary–I’m a tad behind (understatement alert) on email at the moment.

I have a particular affinity for The Kon-Tiki Expedition. I found a 1950s copy of the book while doing my undergraduate degree ages ago.

My 1950s copy of The Kon-Tiki Expedition in an archival cover.

The book played no small part in my fascination with anthropology–especially Heyerdahl’s version of “applied” anthropology. I went on to do my post grad work in anthropology at the London School of Economics. Indeed, I re-read that book before my finals to remind myself the significance of anthropology.

If you haven’t read The Kon-Tiki Expedition, I highly recommend you do so! Indeed, it’s about time I read it again.

I’m very curious how many SWLing Post readers have a National NC-173 sitting in their shack? Thor would tell you to take care of it, because it certainly took care of his crew!

Radio Fax: Christopher seeks more information about “Britain’s Number Two Short Wave Station”

Many thanks to SWLing Post contributor, Christopher Brennen, who writes:

I hope you’re keeping well. I stumbled across this site and thought you might be interested:

http://radiofax.org

I am a little too young to know anything about this; not only was I five / six when they first started but I also had no idea about shortwave radio at the time! 🙂

Do any of your readers know anything more about it (it is fairly detailed on this site, but perhaps someone reading was involved in some way?)

It seems to be a shortwave combination of the IBA Engineering Broadcasts for the trade that were shown on TV and something akin to the current InRadio (inrad.io).

Incidentally, the little IBA jingle at the start of that clip was also used – in a higher key – by Granada Television in the North West of England for some of their idents:

Granada was my ‘home’ ITV region so I’m very familiar with that jingle.

Thanks again for the SWLing Post!

Many thanks, Christopher!

I’m willing to bet SWLing Post readers can comment with more details about the Radio Fax service.

VOA museum marks 75th anniversary with gala

(Source: Journal News via Howard Bailen)

WEST CHESTER TWP. The National Voice of America Museum of Broadcasting will host “Celebrate the Voice of America under the Stars,” a romantic, Big Band dinner-and-dance party on Sept. 23 from 6 to 11 p.m. at the VOA museum.

The event will mark the 75th anniversary of the Voice of America and commemorate the Sept. 23, 1944 dedication of the VOA-Bethany Station.

Carmon DeLeone and his New Studio Big Band will provide entertainment and record a program for later broadcast on public radio station WVXU.

[…]For 50 years, the VOA-Bethany Station transmitted Voice of America broadcasts to countries worldwide that lacked a free press, first in Europe during World War II and to South America during the Cold War. It was decommissioned by the federal government in 1994.

The iconic art deco building has been developed into the National VOA Museum of Broadcasting with the help of the entire community, mostly with volunteer labor. Contributions and grants have been secured from local, regional and national companies and foundations.[…]
