Ham radio activation of North Korea

The ARRL reports the first amateur radio operation from Pyongyang, N.Korea in 13 years took place on December 20.

In an unexpected turn of events, Polish DXer Dom Gryzb, 3Z9DX, who has been visiting North Korea this week in advance of a planned Amateur Radio operation early next year, came on the air from the most-wanted DXCC entity around 0000 on December 20. P5/3Z9DX has been active on both 20 meters and 15 meters SSB only, and a few hundred stations have been fortunate enough to work him.

Propagation was unfavorable due to a geomagnetic storm that seems to have affected his efforts on 20 meters. He also reported that he faced extremely high ambient noise levels in Pyongyang. He ran 100 W to a vertical antenna mounted on a metal fencepost some 7 feet above the ground among government high-rise buildings.

Time station CHU in The Empire Strikes Back

Fullscreen capture 12202015 40448 AM

Earlier today, I published a post noting that I thought I heard the time station WWV in a scene of The Empire Strikes Back.

SWLing Post reader, RadioGeek, quickly corrected me: that’s Canadian time station CHU‘s data pips I’m hearing, not circa-1980s WWV.  Cool!

Listen for yourself

Here’s the clip from The Empire Strikes Back, Battle of Hoth

Now listen to the recording of CHU I made only moments ago–note the tone and duration of the data pips:

No wonder I mixed up CHU and WWV; I’ve listened to both for propagation since I was a kid.

I wonder which of the Lucas Film sound engineer(s)/artist(s) chose CHU for this scene? Anyone know, by chance? Or can anyone find out?

No doubt, that sound designer is an SWL or ham radio operator. Perhaps this may also explain the SSB-esque radio dialog between fighter pilots throughout the Star Wars films:

Jonathan shares archived Media Network Christmas and New Year shows

Many thanks to SWLing Post contributor, Jonathan Marks, who shares the following from his Media Network Vintage Vault.

“Picking up on the idea of revisiting archive Christmas and New Year shows, here are some from Radio Netherlands for the SWL Blog.

Seasons Greetings, Jonathan”

Media Network 26.12.1996 Boxing Day Show

A radio Christmas spent in the Media Network studio way back in 1996. Sounds like we were having fun! I look back on this period as perhaps one of the golden years for Dutch external broadcasting, producing a range of documentary productions in English and Spanish and recording great concerts, both classical and jazz.

This programme focussed on answering listeners’ letters on subjects like satellite television in Australia (DW was organising a bouquet of signals) and the major changes to the commercial radio scene in New Zealand. The auction of FM frequencies in the Netherlands and shortwave stations that sold radios were also topics for discussions. RBI archives have, for the most part, been destroyed. Swiss shortwave listeners were quizzed on their listening habits. The 410 ft tower formerly used by AFN has been dynamited out of existence. Capital Radio in South Africa is in trouble.

MN.28.12.1995 Rhodesia – Answering Back From Francistown

I met the late Harold Robin a couple of times at his home in Tunbridge Wells, UK. He was a brilliant Foreign Office engineer who built the wartime Aspidistra transmitter famous for its clandestine work out of Crowborough. Have a listen to the programmes Wartime Deception and you’ll see what I mean.

Although his work during the war is well documented in books like “The Black Game”by Ellic Howe, I think we managed to capture the other stories from later in his life. For instance, how he invented the “Picolo” modulation system as used by the diplomatic service to communicate text over shortwave between embassies. He also built the BBC Overseas relay station in Oman, and the external service of UAE Radio from Dubai. This edition, recorded after Christmas in 1995, looked at the story of the British response to the declaration of independence by Ian Smith in, what was then, Rhodesia. Harold talks about setting up a mediumwave transmitter in a matter of weeks in the town of Francistown, in the Bechuanaland Protectorate, now called Botswana. Thanks also to Colin Miller for some of the recordings of the RBC. It seems that one of the two transmitters was sent to Cyprus after the World and Rhodesia operation ended, the other ended up in Ordfordness for some experiments on 648 kHz. You might also want to check out the video of Margaret Howard, who refers to a special programme transmitted over this MW sender. It was called the World and Rhodesia and was more of a UK government editorial than any programme the BBC would make. The programme concept didn’t work although it seemed to have taken the British government a couple of years to find out. Harold refers to staying in the Tati Hotel River Lodge, about 8 kms outside of Francistown. Sure enough, it’s still there.

MN.23.12.1982: Christmas Review 33 years ago

I picked this recording out of the archives because it has a nice capsule summary of the major media stories from 1982. The highlight was, of course, the Falklands-Malvinas “conflict”. This programme contains clips from the FIBS, RAE Argentina and the BBC’s Calling the Falklands Programme. We also looked in some detail at the short-lived Radio South Atlantic which broadcast in May and June 1982 from a requisitioned BBC transmitter on Ascension Island. We asked the British Ministry of Defence to explain how the station was operated. We also analyzed a transmission broadcast on May 20th 1982 (the second night of transmission).

But it was also the last programme in which Wim van Amstel appeared as RNW Frequency Manager. It was certainly not the last time he was heard on the programme, though. Again it is striking to hear some of the predictions – and how they were spot on. The call with Arthur Cushen in New Zealand is rather like making contact with the moon. Cannot believe how fast time has flown.

At the time of publishing this podcast, I was also sad to hear of the passing of BBC correspondent and broadcaster Brian Hanrahan, who famous line when broadcasting under censorship from the Falklands Fleet was brilliant. Unable to reveal how many British aircraft had been involved in the conflict, he reported that after one sortie he “counted them all out and I counted them all back.

MN.26.12.1991.Year End Review

This was a news show 1.6 million tune in to Radio Netherlands in Dutch during their summer holiday. WWV and WWVH have had problems with their automated time announcements. Drum recorders are back on line. Victor Goonetilleke has news about Cambodia. VOA is having challenges building its transmitters at a new site 50km North of Colombo.

Why did we broadcast all these numbers? People forget none of the listeners had access on-line and only a fraction of the audience had access to printed DX bulletins. Andy Sennitt reports on what is in the 1992 World Radio TV Handbook. James Robinson reports that several UK local radio stations are leaving mediumwave. WLS 890kHz is scrapping its FM format. A new Catholic SW station WEWN was being built in Birmingham, Alabama. (The late) Dave Rosenthal reports on an experiment in McMurdo. Remember this show is 24 years old!

Vasily Strelnikov signs off at Radio Moscow World Service and recommends people to tune into Radio Netherlands. Radio Moscow staff watch the red flags of the USSR being lowered.

Thanks so much for sharing these, Jonathan–and Season’s Greetings to you!

I’m looking forward to several hours of listening over the coming days.

The Empire Strikes Back: Is that WWV I hear?

Fullscreen capture 12202015 40448 AMWith all of the Star Wars: The Force Awakens hype going on, I remembered that, as a kid, I thought I heard WWV in a scene from The Empire Strikes Back.

I looked through some video clips of the movie online and discovered it again this morning: I heard the WWV-like sound in the Battle Of Hoth scene. [Update: RadioGeek suggests this may actually be CHU’s date pips.]

This video clip will start around the :23 second mark; start listening for the metronomic tick in the background around :25 seconds and then again at :40 seconds:

I may be mistaken, but I believe that sounds like 1980s era WWV. Has anyone else noticed this?

Avo’s review of the Digitech AR1946 shortwave portable

digitech-AR1946-front

The Digitech AR1946

Digitech has released their latest shortwave portable: the Digitech AR1946.

If you live in Australia or New Zealand, you’re probably familiar with the Digitech brand which is sold at JayCar Electronics. If you live in other parts of the world, you may never run across a Digitech (branded) portable.

Digitech-AR1946-box

SWLing Post reader, Avo, purchased the new AR1946. He commented with the following brief review (I inserted a few product photos from JayCar):

[The] AR1946 is now out. Had one for a day but ended returning it as shortwave was full of garbage. Fully DSP based according to the box.

Digitech-AR1946-Front-Handle

I do have to say that FM performance is superb. Sensitivity and selectivity is better than any previous radio I have used and RDS is very usable even on weak signals. 10 kHz steps with a very smooth non muting dial make it a pure DX machine in my books for FM.

Digitech-AR1946-R-sdie

Digital [DAB+] is ok but kept cutting out even with good signal strengths. AM modes have 7 bandwidths that work very well. MW is a bit dull but no images.

Digitech-AR1946-Left-s

If only SW was good I would recommend it as a good all rounder but at $219 for just a great FM tuner I think it’s expensive.

Digitech-AR1946-Back-S

Saying all this, the unit feels good quality wise and in my opinion is a better attempt than the [Digitech] AR1945.

Digitech-AR1946-Front-1

I think a revision can sort out SW and if so, I am definitely repurchasing….

Many thanks for your assessment, Avo!

It sounds like your unit suffers from the same problems many recent DSP portables have experienced: a high noise floor. This was the issue affecting the recently released Degen DE1103 DSP.  I’m not sure why this is happening more in some of the most recently released receivers, but I assume it has to do with poor engineering and internal shielding.

I bet that the noise level may vary unit to unit. Avo, you might ask for another to test before getting the full refund (if Jaycar’s return policy allows).

Have any other readers put the Digitech AR1946 on the air? Please comment!  Click here to view the AR1946 at JayCar Electronics.

Ukraine to launch radio station for troops

Disputed Ukraine Map via Wikimedia CommonsMany thanks to SWLing Post reader, David Iurescia (LW4DAF), who shares this article via Sputnik News:

Ukraine plans to launch a new radio station for the military in 2016.

Alexei Makukhin, an advisor to the Ukraine’s Defense Minister, said during a press briefing that a new Ukrainian radio station for military personnel will begin operating on March 1, 2016.

“It’s no secret that our troops on the frontline often suffer from an information vacuum,” Makukhin said. “So we need a radio station. Seventy percent of its content will be music; there will also be news broadcasts and programs for the troops – where soldiers can say hello to their friends and relatives, request songs and share stories live on air.

There will also be programs featuring interviews with experts and military personnel.”

The new radio station will be reportedly funded by Spirit of America, a non-profit company which assists US military personnel deployed in Iraq, Afghanistan and Africa.
