Dan shares photos from journalist trip to Zanzibar in 1986

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

Here’s a blast from the past that might be interesting reading for the SWLing Post.

Back in 1986, just before ending my three year tour as VOA East Africa bureau chief, I had an opportunity to visit Zanzibar, with a group of journalists. Back then, Zanzibar was still under the socialist government in charge at the time, and was still attached to Tanzania’s socialist government.

Zanzibar town was full of old structures, and clay/stucco type buildings [see photo at top of page]–it was a wonderfully exotic place, with pristine beaches. The main hotel at the time was in poor condition — this was way before any of the extensive hotel development that the island has seen in recent decades.

One day we were traveling across the island, but I made a point of stopping at what was then still Radio Tanzania/Zanzibar. This was of course years before that station would become ZBC, which remains on the air today, and that time the power was still far lower than the station we know today that serves some fairly wide sections of East Africa and up into the Gulf region.

I hadn’t remembered snapping this photo, but found it recently while going through some old prints. This is what I believe to be Radio Tanzania/Zanzibar as it looked back in 1986 [see below].

Another photo [below] shows old Zanzibar town (shot taken from just off the shore).

Two other shots [below] show a graveyard on Grave Island, off Zanzibar, with one of the stones belonging to someone named Henry Bodley Carpenter (click here for more info) who served on the H.M.S. Briton and died in 1873.

Thanks so much, Dan, for taking the time to share these photos of Zanzibar with us. I imagine your work with the Voice of America took you to many corners of our wonderful planet!

I still get a small thrill when I put Zanzibar in the logs! Thank you again.

The history of Deutsche Welle’s interval signal and signature tune

(Source: Deutsche Welle via Mike Hansgen)

Beethoven on the air: the DW signature tune

When Deutsche Welle went on the air 65 years ago, the broadcaster opted for a melody from “Fidelio” for its signature tune. Ludwig van Beethoven’s opera is about an act of liberation.

A political prisoner is starved and nearly tortured to death because the prison’s military governor knows that the prisoner could incriminate him. The incarcerated man’s wife masquerades as a young man and, thus camoflaged, makes her way into the dungeon. When the governor attempts to stab the prisoner, the woman jumps between them and pulls out a pistol. At that very moment, trumpets sound out and the Minister, a higher authority, enters the scene. A friend of the prisoner, he recognizes what has been going on and sets the political prisoners free.

At this happy ending of the opera “Fidelio” by Ludwig van Beethoven, Minister Fernando sings the words “Es sucht der Bruder seine Brüder” (The brother seeks his brothers), and continues: “Und kann er helfen, hilft er gern” (And if he can help, he does so gladly.)

The melody to the words is anything but catchy; it is nearly ungainly in fact. Nonetheless, it was chosen as the signature tune when Germany’s international broadcaster began its shortwave radio transmissions on May 3, 1953.

The symbolism in the words

The choice not only had to do with the musical motif, but was also based on the symbolism in the words. Only eight years after World War II’s end, building new friendships and international relationships was no easy task for the new Federal Republic of Germany.

One sought to proceed in a “brotherly” manner with listeners and partners abroad through friendly exchange. Trust was to be built in a fair and impartial sharing of information.

For many years, the melody, played on a celesta keyboard, penetrated the constant ebb and flow of interference noise on the shortwave radio spectrum. It thus made its way to the speakers of shortwave radio sets around the world – often in endless repetitions leading up to the news at the top of the hour.

The broadcaster then had its headquarters in Cologne, and the Beethovenfest classical music festival took place only sporadically in Bonn, 30 kilometers upstream the Rhine.

The move from Cologne to Bonn, and the media partnership with the re-established and much bigger music festival, had to wait until the new millennium. Then it seemed only fitting that Deutsche Welle should once again associate itself with Beethoven.[…]

VOK shifts broadcast schedule due to North Korea time zone change

Many thanks to SWLing Post contributor, DanH, who writes:

I put up a couple of videos on my “Willow Slough DX” YouTube channel nine hours ago that may rate at least an Arte Johnson (Laugh-in) “verrry interestink”. These are two videos of the North Korean shortwave station Voice of Korea operating with their new time zone and on their new schedule.

These are the two most recent videos of SW station receptions that I have posted during the last couple of days.

[The first video] is the VOK shortwave sign-on recorded at the newly scheduled time of 04:00, May 5, 2018 UTC on 15180 kHz. Distance: 5600 miles. Receiver: Sangean ATS-909X. Antenna: suburban 83m horizontal loop. Receiver location: Davis, California, USA. North Korea has changed its time zone to match UTC +9 which is used by South Korea. I was accustomed to tuning in Voice of Korea at 38 minutes past the scheduled hour for the English language news. Now I tune in at 8 minutes past the same hour. VOK broadcasts that were scheduled for 04:30 UTC now begin at 04:00 UTC. At the time I write this VOK shortwave programs listed on Short-Wave.info still show the old times:

[The second video] is the VOK shortwave newscast at the new time of 04:08, May 5, 2018 UTC on 15180 kHz. Some interference is heard half way through the clip:

Thanks for sharing this, Dan!  It never crossed my mind that VOK would change their international broadcast time based on the fact they shifted their country’s time zone. From a North Korean perspective, though, I suppose this makes sense. Thanks for the tip!

“Burundi to suspend BBC and VOA radio broadcasts”

(Source: The Independent via Mike Hansgen)

Nairobi, Kenya | AFP | Burundi’s press regulator on Friday said it was suspending broadcasts by the BBC and Voice of America (VOA) by local radio stations ahead of a constitutional referendum on May 17.

The head of Burundi’s National Communications Council told journalists in the capital Bujumbura that a six-month ban would come into force on Monday.

Karenga Ramadhani accused the BBC and VOA of “breaches of the law governing the press and ethics”.

The BBC, he said, “damaged the reputation” of President Pierre Nkurunziza during a discussion programme and had “ignored” previous warnings.

Burundi’s government earlier this week urged the regulator to “take action” against the BBC which it accused of spreading “incendiary statements… hatred and subversion”.

VOA is accused of spreading “very tendentious” information and hiring a journalist “sought by Burundian justice”.

French broadcaster RFI also received a warning for disseminating “tendentious and misleading” information.[…]

Dan spots a rare Eddystone 40A HF receiver on eBay

Many thanks to SWLing Post contributor, Dan Robinson, who shares a rare Eddystone 40A find on eBay. Dan notes:

What is interesting also about this is the similarity to the Drake SW8 — notably the
carrying handle.

40A s are rarely seen on the used market, and in line with other older Eddystone
equipment, they are built like a tank.

I agree, Dan! This receiver is built like a tank! It would be a seriously fun (though relatively heavy) field radio–I love how even the chassis corners are rounded and the entire radio can be protected for transport. Obviously, these were designed with durability and stability in mind. Great find and thanks for sharing!

Sound Designer Ben Burtt Reveals Radio’s Influence in Star Wars films

Today is popularly known as Star Wars Day––and I’m reminded of one of my favorite posts, featuring Star Wars sound designer, Ben Burtt, who to my surprise, contacted me to answer a question I published here on the SWLing Post.  Once again, here it is. Enjoy!  And “May the fourth be with you!”


StarWars-LogoSWLing Post readers may remember a post I published in which I believed I’d identified a familiar shortwave time signal station in the Battle of Hoth scene from The Empire Strikes Back.

To recap, here’s the scene in The Empire Strikes back–listen carefully:

Now listen to the recording of Canadian Time Station CHU I made recently–note the tone and duration of the data pips:

Upon hearing this, I went so far as to muse that the Star Wars sound designer might be a radio listener. I asked our readers if anyone could confirm this–?

Well, we’ve got our answer!  I’m truly indebted to an SWLing Post reader who passed my post along to his friend, Ben, who could provide this definitive response:

“This is Ben Burtt, sound designer of the Star Wars films. A friend sent me a link to this blog thinking I would like to comment.

Ben and old recorders

Ben Burtt with his recording gear, circa 1980. The mike on the stand at Ben’s feet is one from his grandfather’s ham radio station in the 1950s, or possibly earlier.

“The answer is yes, I have always been a ham radio enthusiast.”

“My grandfather, Harold Burtt, operated W8CD out of his home in Columbus, Ohio 1930s-1960s. I was enthralled as a kid listening to the sounds on his receiver. I heard alien worlds and cosmic ‘voices.’

Harold Burtt, (Chairman of the Psychology Dept Ohio State) with his attic gear approximately 1935

“So not only did I record his radio, but continued to do so on the Star Wars series and Star Trek as well.

My memory of the Hoth transmission was that it was WWV but it could have been CHU since I was recording all that interested me on the dial.”

Terrific! Thank you, Ben, for taking the time to respond. As I said, you’ve certainly started off this radio enthusiast’s year on the right wavelength…no doubt some of our readers will agree.

Indeed, the powerful sonic experience of the Star Wars and Star Trek films has, in my estimation, helped shape many of us into the radio/sound enthusiasts we’ve become–myself certainly included. Thank you, Ben, for this!  You’ve sharpened my ear to a greater appreciation of sound, especially filmic sound, and your work in particular.    

For readers who are less familiar with Ben Burtt’s work, check out his Wikipedia page and IMDB profile–you’ll find he’s been the sound designer on numerous influential films including the recently released Star Wars: The Force Awakens.

A special thanks to Ben Burtt for sharing these wonderful photos and kindly giving me permission to use them here on the SWLing Post.  I must say, considering my love of radio in the thirties, I especially like that photo of Harold Burtt (W8CD) in his shack.

A full report from Gary DeBock’s Cook Islands (Aitutaki) Ultralight DXpedition

Many thanks to SWLing Post contributor, Gary DeBock, who shares the following notes from his Cook Islands Ultralight DXpedition:


“Frequent Flyer” FSL antenna – Lagoon beach DXing setup photo

Checking out transoceanic DX propagation at an exotic ocean beach site can provide the hobby thrill of a lifetime– if a DXer is lucky enough to choose the ideal time, place and gear to make the chase. All of these fell into place in an amazing way during a 5-day trip to Aitutaki Island (2600 miles due south of Hawaii) with Ultralight radio gear, resulting in the reception of MW stations in India, Bangladesh, Mongolia and Cambodia– all at over 6,800 miles.

Because of extensive QRM from Australia and New Zealand the total number of Asian stations received was limited, but it was definitely a case of quality over quantity. Phenomenal gray line propagation around sunrise shut down Japanese signals almost completely, but boosted up those from the exotic countries in east and south Asia. Korean station reception was limited to the big guns, which was also primarily true for Chinese signals. Except for the ANZ pest QRM, the conditions seemed custom-designed for a west coast DXer to go after the exotic stations which rarely– if ever– show up in BC, Washington or Oregon (even though the Cook Islands’ distance to them is greater).

7.5 inch loopstick C.Crane Skywave SSB Ultralight

Ocean beach propagation at sunrise was strong enough to bring in both 693-Bangladesh and 1431-Mongolia at S9 levels almost every morning on my Ultralight gear, and allow both 657-AIR and 918-Cambodia to break through ANZ QRM on April 12th. No doubt many more of these exotic stations could have been logged except for Australian QRM on 576, 594, 872, 883 and 1566, but this only added to the thrill of the chase. The overall results were exceptional for a DXer using only a 7.5 inch loopstick Ultralight radio and 5 inch “Frequent Flyer” FSL– all designed to fit within hand-carry luggage, and easily pass through airport security inspections. Thanks very much to Alokesh Gupta, Hiroyuki Okamura, Jari Lehtinen, Chuck Hutton and Bruce Portzer, who all assisted in the identification of these stations!

657 All India Radio Kolkata, India, 200 kW (8,075 miles/ 12,995 km) Recorded by accident during a sunrise check of the Korean big guns at 1641 on April 12, reception of this longest-distance station went unnoticed until file review after return to the States. The female speaker (in the Bengali language) is the third station in the recording, after the female vocal music from Pyongyang BS and the Irish-accented male preacher from NZ’s Star network. Her speech peaks around 40 to 50 seconds into the recording. The isolation of the Star network at the 55 second point was done by the Ultralight’s loopstick, not by the propagation. Thanks to Alokesh Gupta for the language and station identification:

657 Pyongyang BS Pyongyang, N. Korea, 1500 kW Like most east Asian signals the N.K. big gun sounded pretty anemic in the Cook Islands. Its female vocal music at 1641 on April 12th shared the frequency with NZ’s Star network (Irish-accented preacher) and AIR’s female Bengali speaker:

693 Bangladesh Betar Dhaka, Bangladesh, 1000 kW (7,960 miles/ 12,810 km) Probably the biggest surprise of the DXpedition, with S9 signal peaks on 4 out of 5 sunrise sessions. Frequently snarling with the Oz pest 3AW, it usually managed a few minutes on top of the frequency each morning from 1630-1700 UTC. Exotic South Asian music was the usual format, and was very easy to distinguish from the talk-oriented format of 3AW (and other Oz co-channels). This first appearance at 1652 on 4-10 featured a “Bangladesh Betar” ID by a male speaker at 8 seconds into the recording (thanks to Chuck Hutton for listening):

This was followed by a lot of exotic music until 3AW claimed the frequency just before the 1700 TOH:

774 JOUB Akita, Japan, 500 kW Oddly enough, this was the only Japanese signal making it to the island during the entire trip. Mixing with a goofy-sounding 3LO announcer at 1613 on 4-11, the Japanese female speech concerns a “doobutsuen” (a “zoo” in Japanese, similar to what the frequency sounded like with the 3LO announcer):

819 KCBS Pyongyang, N. Korea, 500 kW The N.K. big gun managed a potent signal for its 3+1 pips across its “TOH” at 1630 on 4-12 but never could shake off RNZ’s Tauranga transmitter:

909 CNR6 Quanzhou, China, 300 kW Strong signal with CNR ID (1:08) and Mandarin speech by male and female announcers. NZ’s Star network was apparently off the air at the time, since it was a real blaster when transmitting:

918 RNK Phnom Penh, Cambodia, 600 kW (6823 miles/ 10,981 km) Breaking through the Shandong and Oz QRM at an ideal time to dominate the frequency, its sign off transmission with the National Anthem peaked just before the 1700 TOH on April 12. Female speech in the Khmer language and exotic music are featured just before the anthem (thanks to Hiroyuki Okamura and Jari Lehtinen for listening, and identifying the National Anthem):

918 Shandong RGD Synchros (Multiple) The dominant Asian signal on the frequency, it rarely allowed Cambodia to sneak through. Here it is with female Mandarin speech at 1647 on 4-11:

Shandong RGD’s transmitters were poorly synchronized, resulting in the two-tone time pips at the 1700 TOH on 4-12 (during Cambodia’s National Anthem at 1:40, in the MP3 linked below). Although actually from two different transmitters, the sound effect sounds similar to that of a “cuckoo clock,” resulting in some initial confusion about their source:

981 CNR1 Synchros Changchun/ Nanchang, China, 200 kW/ 200 kW The first of three CNR1 frequencies which usually produced strong signals, this music // 1377 was received at 1624 on 4-12:

1377 CNR1 Synchros (Various) Overall this was not only the strongest Chinese frequency on the band, but was the strongest Asian station on the band as well. Awesome S9+ signals were typical each morning, as with this male speech and music at 1622 on 4-12:

1431 Mongolia (Relay Station) Choibalsan, Mongolia, 500 kW This station was easy to receive on the first attempt, with very little competition on the frequency. It typically managed an S9 signal after 1630 daily with the BBC’s Korean service, which seemed to be broadcast during the peak sunrise enhancement time in Aitutaki’s ocean-boosted propagation. Here is BBC’s Korean male announcer at an S9 level at 1632 on 4-11, with the BBC interval signal at 47 seconds into the recording:

1566 HLAZ Jeju, S. Korea, 250 kW A very poor signal was typical during this trip, with the Chinese service barely showing up under 3NE and two other DU English stations (probably 4GM and Norfolk Island). Whenever 3NE was in a fade it had a chance, since other two co-channels were running very low power. Here is the latter situation, with the weak Chinese barely audible under the DU English snarl at 1641 on 4-12:
