National Radio Day 2012

Today in the US, it’s National Radio Day–a day to acknowledge the significance of radio technology and the way it has shaped our past, shapes our present, and continues to shape our future.

National Public Radio and its member stations typically celebrate with some fanfare. I especially love their vintage-inspired graphic this year, featuring Guglielmo Marconi.

In fairness, we should also acknowledge Nikola Tesla, whose 17 patents may have helped Marconi win his Nobel Prize as the father of radio.

Update: REE’s Cariari de Pococi transmitter

Yesterday, I posted that REE’s Cariari de Pococi transmitter has been causing significant spurious transmissions.

This morning, I received the following message from REE:

We are very thanked for your feedback about the reception in SW. We are certainly going to investigate […] and will send your report to the transmitter site.

They also indicated that it could be caused by a multiple harmonic, possibly local to my receiver. Since this problem has been documented by others, including Glenn Hauser, I know it’s a transmitter problem on their end.

Regardless, I’m very pleased they’re taking this seriously.

REE’s Cariari de Pococi transmitter malfunctioning

For several weeks, I have noticed that Radio Exterior de España’s Cariari de Pococi transmitter has been sending spurs up the band during broadcasts on 17.850 MHz.

I’m certainly not the only one who has noticed, either. Glenn Hauser has mentioned his frustration with this continuous band pollution on several episodes of GH’s World of Radio broadcasts. It seems that contacting REE is not improving the situation.

The spurs are actually travelling up as far as the 17 meter amateur radio band. Today, while on 18.118 MHz, I could hear the tell-tale signs–pops and crack sounds with a faint voice signature. I recorded what it sounds like in AM on 18.118 MHz–click here to listen.

When I turned on the spectrum display of my WinRadio Excalibur, I could see as well as hear that it was emanating from an REE sports broadcast on 17,850.

Below are some screen shots of what the spur looks like on a spectrum display. If you compare the two images it’s easy to see. (Note that spurs appear as flashes on the spectrum and are not constant, like noise level or other “clean” AM carriers.)

If a domestic AM broadcaster in the US was causing this type of harmful interference, a correction would be enforceable, and most likely, the station would be taken off the air until the problem was solved. The transmitter is harming other broadcasters and the amateur radio spectrum. It’s an embarrassment for REE, too–their signal is quite strong into North America and I would otherwise love listening to them. While their transmitter is malfunctioning, however, their fidelity is compromised with distorted, “splattering” audio.

If you have noticed this, please consider sending a message to REE’s main email address: [email protected]

Perhaps if they receive enough complaints, they will take action.

Shortwave Radio Recordings: Radio Kuwait and music variety

Any of you who’ve been following the SWLing Post for a while know how much I love recording music over the shortwaves. Lately, Radio Kuwait has been booming into my part of eastern North America with great vivacity.

Yesterday, I recorded several hours of their broadcast on my WinRadio Excalibur. I couldn’t help but notice, the last time I posted a recording, that their music had a great deal of variety. Their mix yesterday afternoon encompassed hip hop, country, pop, rock, R&B, and even a little Billy Joel and Donovan.

Though the hip-hop and boy bands don’t particularly hold my personal interest, hearing “Mellow Yellow” over 7,000 miles of ether certainly has appeal.

If you’re looking for music variety (well, a lot of variety), with some items of cultural interest thrown in, check out Radio Kuwait:

Shortwave Radio History: 50 years of transmitting at BBC Woofferton

Click here to download your copy.

Thanks to the efforts of a dedicated radio historian and author, Jeff Cant, you can download and read an excellent history of the first fifty years of the BBC’s Woofferton transmission station. Cant began his history as an internal document to the station; he later finished it in his retirement. I wish every shortwave transmitter station had such a well-documented history providing a perspective on the station’s broadcasting. We owe Mr. Cant a profound debt of gratitude.

To download the PDF, simply click here.

A special thanks to Jonathan Marks for finding and sharing this great bit of radio history.

Should the link to the PDF above ever become inactive, I’ve placed an archive copy available for download on the SWLing Post server.

VOA: Malian journalist attacked on air, listeners search and rescue

(Source: VOA News)

A Malian journalist who was hospitalized after being beaten by Islamist militants in the northern city of Gao Sunday says he was unconscious after the attack.

Speaking from his hospital bed Tuesday in Gao, Malick Maiga Aliou told VOA’s French To Africa service that men “armed to the teeth” entered the studios of radio Adar Koima during a live broadcast and dragged him into a car.

He says the gunmen beat him with rifle butts and other objects, accusing him of spreading lies about them.  Eventually, he says, they dumped him at a local cemetery where they stomped on him and left him for dead.

Local residents who heard the attack live on the radio organized a search for Aliou, who was found unconscious and taken to a local hospital.

The beating, Aliou’s third at the hand of Islamists, appeared to be punishment for reporting that local residents had prevented the amputation of a thief’s hand on Sunday.

The Malian journalist also contributes stories to the Voice of America.  VOA’s director David Ensor condemned the attack and applauded the local residents who came to Aliou’s aid.

The Islamist group MUJAO, which controls Gao, insists on imposing strict Islamist laws in the region under their control.  But local residents organized a protest Sunday to prevent the amputation of the young thief’s hand.

MUJAO and other Islamist groups took over control in northern Mali following the March coup in the capital Bamoko.

Last week, in the small Malian town of Aguelhok, another armed Islamist group, Ansar Dine, publicly stoned an unmarried couple.

Mali’s government has condemned the stoning as well as the attack on the journalist.

Malian interim President Dioncounda Traore has recently returned to Bamako after two months in Paris, recovering from a violent attack by opponents to his appointment.  He vowed the government will retake the north.

Fifteen-member regional group ECOWAS has proposed deploying more than 3,000 troops to help restore order in Mali.
