The new Degen DE1129 shortwave radio with MP3 recording and playback

(Photo source: TecsunRadio.com)

TecsunRadio.com has posted the new Degen DE1129 shortwave radio on their website. Though they have not yet posted pricing, it appears pre-orders are being taken.

The DE1129 looks like a decedent of the Degen DE1128 that has not exactly been a market success in North America. The DE1128 lacks medium wave (AM) 10kHz steps (spacing) that allows it to be useful in the North America AM broadcast market.  It also lacks English as a selectible language on the display. (The Grundig G2 Reporter, however, does have the features and is, in essence, the North American version of the DE1128).

The published features/specs of the new DE1129 do not reveal if AM spacing or English language will be an issue in the DE1129. I will try to contact the manufacturer. Until then, I would keep this in mind if pre-ordering. UPDATE: The DE1129 does have 10kHz spacing.

UPDATE: Vimal points out pricing is $102 US/each with shipping.

Thanks for the tip from the excellent Herculodge blog!

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.

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.

Tribute to Radio Netherlands Worldwide on the NRC’s DX Audio Service

The National Radio Club requested that I read and record my tribute to Radio Netherlands Worldwide for their audio service intended to benefit their visually-impaired readers. The broadcast is divided into sides A and B (of a cassette tape).

My narration begins about midway through side B.

Jeffrey revives an old friend, his Hallicrafters SX-110

SWLing Post reader, Jeffrey Fritz, sent me the following message and has kindly allowed me to share it with other readers. I’mthoroughly inspired!

Bottoms up! Considering how old this receiver is, the chassis bottom (still with the original power cord) really is clean. This is how the bottom of the chassis looked when I removed the receiver from its metal cabinet.

As a teenager in the 1960s I spent a considerable amount of time SWLing on a Hallicrafters SX-110 communications receiver. I collected QSL cards from all over the world and loved being an SWL.

The SX-110 was purchased on 9 September 1961 from Gem Electronics in Farmingdale, Long Island, New York. My parents bought it for me, probably after a great deal of whining and cajoling on my part. Although much of my gear has long since been sent to some landfill by my parents, like my precious Lionel trains, I would not allow them to trash the SX-110.

The top of the chassis, however, is not as clean. Some elbow grease will clearly be required.

The radio has been sitting in one basement or another, unused for the better part of 30 years.

Yesterday I decided to try bringing the radio back to life. Restoring this kind old receiver was a labor of love. The receiver was carefully looked over and tested with a VOM for bad components and the top of the chassis cleaned as best I could. The bottom was pristine. I just needed to clean out a few cobwebs and replace the power cord.

All eight tubes. Note the three original Hallicrafters tubes with the orange labeling.

After being cleaned up and several components tested, the SX-110 was slowly brought back to life on a Variac. I started at 10 volts AC and slowly increased the voltage every ten minutes by another ten volts. When I got to about 90 VAC, I could hear static and distorted audio coming out of the speaker. It was a good sign that the radio would come back to full operation once I reached the normal 110 VAC input–and that is exactly what occurred.

I am happy to report that, with a little patience and love (and a good cleaning) –and with three of the original Hallicrafters tubes still in place, my trusty old Hallicrafters SX-110 shortwave receiver is happily working today. I have it connected to its original Hallicrafters R-47 3.3 ohm speaker.

The top chassis is cleaned as much as possible. Not perfect, but a little cleaner than before. We now have about 110 volts applied through the Variac. No smoke but we do have lights!

Yesterday evening I listened to Radio Taiwan, Radio China International, Radio Havana Cuba, The Voice of Turkey and The Voice of Russia. The audio quality was rather decent without a hint of AC hum. The radio is probably due for a good alignment. I am running the radio on the Variac set at 110 volts AC and will probably keep it on the Variac because the AC voltages today in the U.S. are significantly higher than they were in 1961.

Even the XYL thinks that the radio sounds terrific! What better recommendation can there be for this old, vintage receiver?

The restored SX-110 sitting on the bookshelf in the shack. No one would mistake this for a new receiver, but it works just fine.

PS–Jeffrey also mentioned to me: “If you look closely at the chassis stamp photo of the SX-110, you can see a stamp that reads ‘199117 C.’ This is the manufacture date of the receiver. The fourth digit is the year, and the fifth and sixth digits are the week of the year. So, 199117 is the 17th week of 1961 or the week of 23 April 1961.”

Very interesting. Now I need to examine a few of my own Hallicrafters receivers…

Close up of the inspection stamps. Do modern rig manufacturers take time to do this now?
