An unusual 1990s reception report from North Korea

Many thanks to SWLing Post contributor, Richard Langley, who spotted this fascinating account in The Mayo News:

Michael Commins on his remarkable communication from inside North Korea

THE Korean peninsula dominates world news coverage this week.

[…]Around 1988, after becoming engrossed in the hobby, I also bought the acclaimed Sony 2001D shortwave radio from Padraig Gilmore of Gilmore Electrical in Claremorris. Padraig was a genius when it came to radios and he also had a huge interest in shortwave listening.
I recall listening to the last broadcast of Radio Berlin and tuning in on a weekly basis to some favourite shows on The Voice of America, Radio Netherlands, Radio Havana (still broadcasting on 6000khz), Radio Prague, Radio Moscow (with their powerful transmitters on numerous frequencies), Radio Canada International, HCJB from Quito in Ecuador, Vatican Radio, and a host of the stations from around the world.

[…]On a few occasions, I managed to pick up the English language broadcast of Radio Pyongyang from North Korea (Democratic People’s Republic of Korea). I posted some reception reports to them and got back their radio schedules and QSL cards as well as some cultural material.

One day in the 1990s, I received an extraordinary letter from a person at the international radio station in North Korea. It was smuggled out of the country and posted in Japan. There was no internet and no Facebook back then. Shortwave radio was the only way to get news broadcast across thousands of miles.

Today, for the first time I reveal some of the contents of the letter but am still reluctant to state the date I received the letter (which I wrote on the back of it) … just in case.

Here are some extracts:
“I am writing this letter to tell you we are tired of repeating the same programs all the year round. We may deal with fresh information when we air the news about foreign countries, but when we are told to air radio commentaries we in most cases try to search similar programs we had once aired previously.

“This is the safest way to be faithful to our duty because we are told to quote some phrases from the remarks of our Great Leader Kim II Sung or Dear Leader Kim Jong II whenever we draft the manuscript of the commentaries. This is why we have been repeating the same tones for years.

“No freedom of speech nor of association exists in my country. You will never notice any dark side of our society when you listen to our radio programs.

“The reality of my country is that the people, especially those living outside of Pyongyang are suffering from the severe shortages of food and daily commodities. They are urged to engage in the campaign to take two meals, instead of three meals, a day.

“I don’t think our closed-door policy will last forever, and sometime, in the future and all of a sudden the people will rise up against the government. I think now is the time for the intellectuals to come to the rescue of our fatherland”.

This letter has been kept safe and sound over the years, between the covers of ‘The Moscow Correspondents’, a fine book by Whitman Bassow, former Moscow Bureau Chief of Newsweek, which provides wonderful insights into the USSR over generations.[…]

Guest Post: Backpack Shack 3.0 – Part 2

Many thanks to SWLing Post contributor, TomL, who shares the following guest post as a his Backpack Shack 3 evolves:


Backpack Shack 3 – Part 2

by TomL

Wanting MOAR options for my recent amplified whip antenna experiment, I decided to add a second antenna input to the kitchen cutting board (can I call it a “Breadboard”? – Ha, that’s an electronics joke!).  The idea behind it came from realizing that I might not want to spend all my time outside at a picnic table or on the beach, especially if it is drizzly and windy. And I still wanted a better ground for the antenna.  So, I thought I could use more Trucker Parts and put an antenna on top of the roof of my vehicle so I could listen in the relative comfort and safety of my small SUV (or even a friend’s car).

Breadboarding

Here is the crowded “Breadboard” with some extra items added.

I thought of the vertical antenna as a short longwire and had an old, original RF Systems Magnetic Longwire Balun.  That device allows for an improvement in signal/noise ratio (in theory) if used on a longwire. Perhaps it works on this, too??  You can see the gray cylinder connected right beneath the trucker mirror mount on the left (this will not be tested at this time, see External Antenna below).  The output goes to a greenish Daiwa switch on the right.

A large amplified antenna has the real possibility of overloading the amplifier.  With the Magnetic Balun, I am hoping the VHF band is attenuated enough to preclude any problems because its response naturally tapers off past 40MHz.  But Mediumwave is well within its bandpass. I remembered an old Kiwa Electronics Broadcast Band Rejection filter not being used for a long, long time, so I connected that right after the Daiwa switch (the metal box with red plate).

This output then goes to an RF choke just before entering the pre-amp.  I figure I will be using my SDRPlay RSP2 and noisy laptop and wanted to try to reduce any interference traveling on the outside coax braid before it gets amplified.

External Antenna

OK, now for the other Daiwa switch selection.  The external antenna will be connected and disconnected as often as I use it.  I attached two right-angle coax adapters to be the connection point for the antenna.   This is so that the physical switch threads do not have to handle that wear-and-tear. You can see it as the fuzzy out of focus thing sticking up out of the left side switch position.

The wire going out the top of the Breadboard goes to a Firestik K-11 magnetic mount placed on top of the roof of the SUV.  I also wanted this to be connected to a magnetic balun. I just happened to have a nearly unused Palomar Engineers Magnetic Longwire Balun.  It has its own ground lug for use with a counterpoise. Temporarily, I left the 18 feet of wire that came attached to the K-11 Mount and attached an adapter and BNC test lead; on the other end is connected the spade lugs to the Balun (red wire to the lanyard nut, black wire to the ground lug).  It all fits neatly inside a Sistema 3 liter container.

The magnet and box self-clamp easily onto the roof of the vehicle.  I added a new 18 inch section to the Trucker Antenna Shafts creating a full 72 inch antenna, complete with mag mount, ground plane (car body), and magnetic balun.  It is very easy to put up and take down and the box helps keep everything contained.

I am pushing things a bit here.  Magnetic Baluns are not really meant to be used on vertical antennas.  It probably breaks some sort of Cosmic Electrical Law somewhere that causes electromagnetic waves to get very confused and die a horrible, twisted, circular death.  But I figure that it is an unbalanced “line” similar to a longwire antenna; it’s just a little short and goes straight up instead of horizontal! I like the idea, so I am going to run with it.

Warnings!

It goes without saying that the Antenna Shafts, magnet mount, and magnetic balun are weatherproof (but NOT lightning proof!).  Take proper lightning precautions and take it down.  Even so, I might add a small drainage hole to the box since it did rain a tiny bit during testing.

Secondly, this setup is ONLY FOR STATIONARY VEHICLES!!!!  DO NOT TRY TO DRIVE DOWN THE ROAD OR HIGHWAY!!!! The magnetic mount will NOT stay on the car and will damage your vehicle and maybe a vehicle travelling next to you!

Performance

As you can see from the picture, my new Tecsun S-8800 is getting a workout while connected to the Cross Country preselector (not shown behind it) and to the backpack next to the back seat window.  The Tecsun S-8800 is a nice radio. My copy has a couple of quirks that I might have to send it back (the AM band tunes incorrectly 2 kHz lower than it should and the SW SSB tunes 140 Hz higher than indicated and I have to compensate using the fine-tuning dial for these modes–FM seems correctly tuned).

Other than this, the actual performance is really quite good!  DSP does have sharp cutoffs to the IF bandwidth (especially resolving strong station interference when selecting 3 kHz vs. 4 kHz).  With all my filters/balun/choke, I did not notice any MW or FM breakthroughs and signals on those bands were nicely contained and “normal”.  Interference from my cell phone while looking up internet frequency listings was minimal – seems like the cable shielding, choke, and car roof are doing a good job.

The audio output jacks have very thin clearance between the jacks and the housing of the radio. So for the second time, I will not have recordings since the cable I wanted to use has home theater style construction with very thick plug outer connectors and will not fit!

From an RF-quiet “Forest Preserve” (County park), there were a variety of stations received from the 25 through 19 meter bands (Local time 11am-1:30pm). A few stations I have never heard before until now:

  • Radio Free Asia in Korean on 11985 KHz (Tinian Island)
  • Radio China International in Esperanto on 11650 KHz (Xian China)
  • Radio Farda in Persian on 12005 KHz (Wooferton England) – broadcast opposite my direction
  • Radio Bible BCI in Somali on 15310 KHz (Nauen Germany) – Strange sounding but interesting  Christian Somali music
  • Radio Free Asia in Chinese on 13675 KHz (Dushanbe Tajikistan)
  • Voice of Hope Africa in English on 13680 KHz (Lusaka Zambia) – had to use ECSS USB to get away from strong interference from RFA on 13675, fairly good intelligibility (including music)!  I wish there was a 6 KHz option for SSB mode since the audio was slightly muffled and could not compensate much with the tone controls. That kind of feature usually comes with radios costing 3X more, however.
  • Voice of Korea in French (Kujang North Korea) being squashed by Radio China International (Kashi China) in English on 13760 KHz

It was so nice not to be on a beach and have people walk by STARING at me with my weird radio/antenna setup.  And I was dry and comfy sipping a cool drink while there was a drizzle of rain pelting the windshield. Downside might be that the car setup cannot always be located optimally if I want to be next to that Very Large Body of Water (Lake Michigan) to help enhance reception but this is not a bad alternative.   The next test will have to be during early evening when signals are booming into my location and see if performance holds up under those conditions!

Happy Listening,

TomL

Self-powered shortwave radio spotted in Battlestar Galactica


Many thanks to SWLing Post contributor, Bruce F, who writes:

Here is a photo of a radio from the 2004 – 2009 TV series “Battlestar Galactica“. This radio is perhaps unique and worthy of careful study! Why? Because not only was it NOT MADE on Earth, but there is no connection in its design with any other known radio ever.

The reason for this is quite simple. This sci-fi TV series takes place in a distant future when all humans had left the Earth generations ago and migrated throughout the galaxy. The humans in this series have lost all touch with humanity’s origin planet. They do not know where Earth is, or even if it still exists, or if it ever actually existed.

“Earth” is an important part of their religion and mythology. So here is a totally un-Earthly radio. Odd though. it does closely resemble a Grundig wind-up radio I owned sometime in the 2000’s…

Ha ha! Yes indeed, Bruce. And I can confidently say that I’ve personally distributed hundreds upon hundreds of this particular radio model for Ears To Our World. Grundig used to market it as the Grundig FR-200, and Tecsun still offers it as the Tecsun Green-88 (or GR-88). It’s a brilliant receiver, although I’m not sure how effectively one can monitor shortwave while in a spacecraft! 🙂

I also grabbed some screenshots from BSG with a number of radios some time ago. I’m not sure I ever posted it, though. I’ll have to look through my (rather deep) drafts folder.

Thanks for sharing, Bruce. I’ll add this post to our growing archive of radios in film!
