From Wikipedia:

Radio Venceremos (Spanish; in English, “‘We Shall Overcome’ Radio”) was an ‘underground’ radio network of the anti-government Farabundo Martí National Liberation Front (FMLN) during the Salvadoran Civil War. The station “specialized in ideological propaganda, acerbic commentary, and pointed ridicule of the government”. The radio station was founded by Carlos Henríquez Consalvi (Santiago).

Despite the end of the war in 1992, the network continues to broadcast. The war years of the station and its national and international influence were documented in the Spanish-language book Las mil y una historias de radio Venceremos and its English translation, Rebel radio: the story of El Salvador’s Radio Venceremos, by the author José Ignacio López Vigil (translator: Mark Fried), a book recorded by the American Library of Congress. An exhibit honoring Radio Venceremos, including a studio room with original equipment, forms a prominent part of the Museum of the Revolution in Perquín, Morazán, El Salvador.

I also found this film on YouTube (The Radio Venceremos Story) which sheds a little more light on the station. The recording is low-resolution, but the subtitles are legible:

OTR: CBS Radio Workshop episode includes interval signal from “Radio Rhodesia”

Many thanks to SWLing Post contributor, Dan Robinson, who passes along this interesting radio show from the CBS Radio Workshop and a description from his friend, Art Chimes.

Art writes:

Airing in 1956-57, The CBS Radio Workshop was an anthology series that featured a wide range of productions, often in experimental formats. On Nov. 11, 1956, the program was “Report on the Weans,” an adaptation of a satirical article by Robert Nathan published in Harper’s Magazine, “Digging the Weans.”

It is 6,000 years in the future. The American continent is unpopulated, but archaeologists from Africa — apparently now the center of civilization — are digging in various sites, uncovering artifacts of the 20th century people who once lived there. In a gentle satire of anthropology, we find the experts completely mis- (or over-) interpreting their findings, such as Macy’s bargain basement, which they think is a tomb full of items to be used in the afterlife.

The magazine article [click here to download PDF] is a straightforward parody of an academic paper. The radio show, however is presented as a report broadcast on “Radio Rhodesia” on the mega-, micro- and strato-beams, complete with an interval signal used at the beginning and end that features bird chirping. (I can’t help you on the particular species, sorry.)

The Listeners: Members of the Women’s Royal Canadian Naval Corps who secretly monitored the airwaves

Many thanks to SWLing Post contributor, Fred Waterer, who shares the following fascinating video from the CBC and notes:

“The Listeners” Members of the Women’s Royal Canadian Naval Corps monitored the airwaves for German U-Boat traffic. Their participation was secret for decades.”

This is such an amazing story, Fred, and the CBC did a fine job putting it together. Thanks so much for sharing.

Editor’s note regarding WWII history: Regular SWLing Post readers know that I’m an avid WWII history buff, in that I read, view, and especially listen to many accounts of the Second World War era, the glory days of radio. I’ve traveled and lived in several of the countries that were, at that time, among the Axis Powers, some of my close friends are from or reside in these countries now, and feel much as I do about this history: that this was a devastating war which we must not forget or romanticize, and from which we can learn about ourselves as human beings, hopefully with the view of preventing such chilling events from ever being repeated.  As we have readers and contributors from all over the world in this radio community, I sincerely hope that WWII-related articles are regarded in this light of understanding. The takeaway? Times have changed.  I firmly believe that a deep understanding of our shared history makes us all better people.

D-Day: 75 years ago today, Operation Overlord initiated wall-to-wall news coverage

Today, as many know, is the 75th anniversary of the World War II battle in Normandy, France, known to history as D-Day. “Operation Overlord,” as D-Day was code named, without doubt, was one of the key turning points of World War II.

But many may not know that D-Day was also one of the first events that brought continuous news coverage via radio on the home front.

As mentioned in this excellent article from MyNorthwest:

“In addition to what it meant as a great turning point in world history, D-Day is also unique in how it was broadcast by American radio networks, as CBS, NBC, and what would become ABC pooled their reporters, engineers and other resources, and cooperated closely with military officials to present, for the first time, what would now be called “wall-to-wall” coverage of a developing major international news event for American audiences.

It’s something we take for granted now in the age of the internet and cable news, but this kind of media coverage can be traced back to D-Day.”

But the widely-covered event was originally top secret.  So secret, in fact, that news agencies in the US first learned about Operation Overlord via not Allied news, but Axis news sources. Thus the information was delivered with caution, since the source wasn’t the War Department of Allied Forces.

A little after 3:30 AM (Eastern War Time), the Supreme Headquarters of the Allied Expeditionary Force (SHAEF) in London produced Communiqué #1, a short statement read twice by Colonel R. Ernest Dupuy, confirming that Allied naval forces, with the support of the air forces, and under the command of General Eisenhower, began landing Allied armies that morning on the northern coast of France.

From the Post Archives: Honoring Memorial Day with Dame Vera Lynn

The following Memorial Day post was originally published on May 25th, 2015:


Dame Vera Lynn

Dame Vera Lynn

Today is Memorial Day, and I’m feeling humbly grateful to all of those who paid the ultimate sacrifice for their country. Since I’ve been reading a lot of WWII history lately, I’ve also been playing a lot of WWII-era music here in my sanctuary to all things radio.

Few songs sum up the yearning sentiment of World War II better than Vera Lynn’s 1942 rendition of “The White Cliffs of Dover.” It’s an iconic song, one that helped British soldiers see beyond the war while mourning its painful toll. It was written in 1941 when England was taking heavy casualties, just before American allies joined the effort.

Scott-Marine-Radio-SLR-M

This morning, seeking something with a little authenticity, I played “The White Cliffs of Dover” though my SStran AM transmitter, and listened to it through “Scottie,” my WWII-era Scott Marine radio (above). I made this recording by placing my Zoom H2N recorder directly in front of the Scott’s built-in monitor speaker.

So here you go: a little radio tribute to all of those who fell–on both sides–of that infamous second world war.

And thanks to all who serve and have served in the name of “peace ever after.”

Lavina Shaw: History of a Canadian railway brass pounder

Many thanks to SWLing Post contributor, Eric McFadden (WD8RIF) who shares the following post by James Wade (WB8SIW) from the QRZ.com forums:

The CBC recently interviewed Lavina Shaw, Past International President of the Morse Telegraph Club. In this biographical documentary, Lavina talks about her experiences working as a railroad and commercial telegrapher as well as her experiences as a woman working in a man’s world. Like many telegraphers of her era, Lavina had a front-row seat to history.

In addition to railroad and commercial operations (telegrams, cablegrams), the telegraph was widely used in a variety of applications such as stock brokerage operations, commodities and board of trade work, press operations, and so forth. Even the telephone company used Morse telegraphy extensively for its internal operations well into the post war era.

Radio amateurs in general, and CW operators in particular, will undoubtedly find this video interesting, not just for the human interest content, but for its insights into the antecedents of radiotelegraphy.

The Morse Telegraph Club is a non-profit historical and educational association dedicated to preserving the history and traditions of telegraphy and the telegraph industry. MTC members and chapters demonstrate telegraphy at historical events, design and construct historically correct museum exhibits and conduct presentations on the history of telegraphy. MTC also publishes an excellent quarterly journal entitled “Dots and Dashes, which includes articles on telegraph history and first-person accounts of telegraph industry employees.

Thanks, Eric, for sharing this fascinating piece about Lavina Shaw!

The Audimeter: A 1939 solution for measuring radio audiences

(Source: Gizmodo)

[…]The February 1945 issue of Radio-Craft magazine included an article titled “Radio Audience Meter” which looked at the machine that was revolutionizing audience measurement. First installed in homes on a trial basis in 1939, the Audimeter was placed next to a family’s existing radio.

The article included photo cutaways that showed how the Audimeter worked. Back in those days, radios had dials. Fitted with a series of gears, the Audimeter was a standalone device connected to a radio. It had an arm that moved whenever the radio dial was turned. So whenever the radio station was changed, the Audimeter’s arm would swivel along a long tape that was slowly rolling inside this gadget. The tape inside was about 100 feet long and three inches wide and reportedly lasted for about a month of recording.

The market researchers would collect the tapes by visiting each house monthly and shipping the tapes to a plant in Chicago. Once there, the tapes were processed by dozens of laborers feeding the tapes into tabulation machines.

“The Audimeter made it more scientific,” Buzzard noted about the measuring device. “They got automatic readings.”

And words like “scientific” and “automatic” were all the rage for gadgets of the 1940s, even if by today’s standards there was quite a bit of legwork involved.[…]
