Tom’s field portable HF antenna snags VOK’s summit broadcast

Tom’s field portable car roof HF antenna.

Many thanks to SWLing Post contributor, TomL, who shares a recording he made of the Voice of Korea on June 14, 2018. This English broadcast focuses on the Singapore summit and is, no doubt, historic in its content. [Note that we’ve posted other recordings on the Shortwave Radio Audio Archive.]

TomL notes:

Recorded on my noisy Lenovo laptop, SDRPlay RSP2, and an unamplified 18.5 foot antenna on the roof of my SUV.

I’m most impressed with the quality of his recording–VOK is not the easiest station to snag in the US midwest:

Thank you for sharing, Tom! I love your field portable vertical–obviously, it’s doing a fine job and your car must make for a decent ground plane!

NSS Annapolis QSLs for SWLs

3 Replies

Front of the NSS QSL card–the back has contact info an excellent explanation of NSS with photos.

Many thanks to SWLing Post contributor, Ulis Fleming (K3LU), who writes:

I wanted to pass along some information regarding the NSS Annapolis radio station.

Last year’s cards were sent out for Armed Forces day with one generic card with all the callsigns. This year the ops at NSS will be sending cards direct on their own to ALL amateur stations who worked NSS without solicitation via their address posted in QRZ.com.

SWLs can send a full SWL report with station worked, time to K3LU via the QRZ.com address or email me for my address at [email protected]. A SASE is helpful but not necessary.

Thanks so much, Ulis! What a great service to the SWL community!

Help record the 2018 BBC Antarctic Midwinter Broadcast

3 Replies

Every year, the BBC broadcasts a special program to the scientists and support staff in the British Antarctic Survey Team. The BBC plays music requests and sends special messages to the small team of 40+ located at various Antarctic research stations. Each year, the thirty minute show is guaranteed to be quirky, nostalgic, and certainly a DX-worthy catch!

After successful listener events from years past, I’m calling on all SWLing Post readers and shortwave radio listeners to make a short recording (say, 30-60 seconds) of the BBC Antarctic Midwinter Broadcast today and share it here at the Post (frequencies and time below).

The recording can be audio-only, or even a video taken from any recording device or smart phone. It would be helpful to have a description and/or photo of your listening environment and location, if possible.

Audio should be in the MP3 format and videos either hosted on YouTube or Vimeo so that I can easily embed them without having to convert and upload myself.

If you submit your recording to me, I will post it here on the SWLing Post–and insure that the British Antarctic Survey receives the post, too. The recordings will be arranged by geographic location.

Frequencies

This year, there have been few details about the broadcast announced in advance–I’ve seen no test broadcast announcements as in years past–so my fingers are crossed that it’ll take place on the air, on schedule.

Please note that the broadcast begins at 2130 UTC on (Thursday) June 21, 2018. The following frequencies were provided by Mauno Ritola who sourced them from a German SWL list serve:

From ASCENSION

7360 kHz

From DHABAYYA

6035 kHz

From WOOFFERTON

7230 and possibly 5985 kHz

I’m sure there will be live reports in the SWLing Post chat room during the broadcast. Please sign in and share your report as well!

I hope I’ll be able to receive the broadcast this year–I’m traveling again, but will have a receiver in tow. Worse case, I’ll snag the broadcast from a WebSDR in Europe (which is a pretty easy catch).

Listening for the Midwinter test transmissions last week with the Elecraft KX2.

The Midwinter broadcast is one of my favorite programs of the year. I suppose, in part, this is because it happens on June 21–the Summer/Winter solstice–which also happens to be my birthday! Woo hoo!

DRM feeds RNZ Pacific relays

RANGITAIKI, New Zealand — Radio New Zealand Pacific, the official international arm of Radio New Zealand, is using Digital Radio Mondiale digital radio transmission/reception equipment to feed studio-quality audio to some of its 20 relay stations in the Pacific Ocean region. The others use satellite feeds or web downloads.

The locations being served by DRM include the Cook Islands, where RNZ Pacific’s programs are rebroadcast locally in analog mode by Aitutaki 88FM, the islands’ only broadcaster. RNZ Pacific also serves Tonga, Samoa, and the Solomon Islands using DRM; among others. Previously, RNZ Pacific had fed its relays using analog AM shortwave radio, with that transmission mode’s limited audio range and interference issues.

“When DRM became available to us in 2005, we saw it as a great opportunity to provide high quality audio to Pacific radio stations that relayed our news broadcasts from our AM transmitter,” said RNZ Pacific’s Technical Manager Adrian Sainsbury. “As a platform to deliver good quality audio to remote island FM stations, it has been a great success.”[…]

As the article points out, RNZ has been using DRM as a feed for quite a few years. I think this is a brilliant use of the technology. Of course, those of us in the rest of the world can snag RNZ DRM broadcasts as well.

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.[…]
