The Rarest DX?

By Don Moore

In mid-October I received an invitation to attend the annual DXpedition in Cappahayden, Newfoundland with Jean Burnell, John Fisher, and Jim Renfrews. It didn’t take long for me to say yes. Newfoundland is one of the best places in the world to DX from and all kinds of amazing stuff has been heard there. I was excited at the prospect of great medium wave DX and being able to log low-powered European private and pirate shortwave broadcasters.

But something else was at the top of my try-for list. One of my many DX interests has always been logging coastal marine stations in the 1600 to 3000 kHz range. In preparation I started checking online sources to update my spreadsheet of schedules. In going through a recently added section on Marine Broadcasts in the DX Info Centre website I came across listings for twice-daily weather broadcasts from Hopen Island on 1750 kHz and Bjørnøya (Bear Island) on 1757 kHz.

I didn’t remember ever seeing anything about broadcasts from these remote islands in the Norwegian Arctic before. Were these stations actually on the air, I wondered. And if they were, could I hear them in Newfoundland? Continue reading

Radio Preservation Task Force announces partnership with the Shortwave Radio Audio Archive and Radio Spectrum Archive

I’m honored to announce that the Shortwave Radio Audio Archive and the Radio Spectrum Archive are now partners of the Radio Preservation Task Force.

Click here to read the official press release.

To say that I’m enthused would be an understatement:  the Radio Preservation Task Force has, as of today, officially partnered with the Shortwave Radio Audio Archive and Radio Spectrum Archive.   

When I learned that the Library of Congress’s National Recording Preservation Board created the Radio Preservation Task Force (RPTF) in 2014, I became an enthusiastic contributor early on, having started a modest preservation project myself only a few years prior.  Then, a partnership like the one created today would have been one of dreams.

As many of you here know, I’m not only passionate about technologic innovations in our radio space, but also preserving our past.

Shortwave Radio Audio Archive

It was in 2012, in response to a round-table discussion at the Winter SWL Fest, that I created the Shortwave Radio Audio Archive (SRAA). Many of us in the radio community were concerned about the number of original, made-from-home, off-air shortwave radio recordings (airchecks) that we knew were in existence, yet were simply disappearing with the passage of time. We were well aware of members of our community who had either passed away or downsized, and many of their recordings––some of pivotal world events––were being tossed out by well-meaning loved ones or friends who simply didn’t understand their relevance. In addition, many of these recordings were captured on magnetic tape, which becomes brittle with time; we knew these recordings were literally turning to dust.  I felt I had to do something.  The SRAA was that something.

Fortunately for me, the SRAA’s mission has really resonated within our radio community. Today, we have thousands of off-air recordings, all freely available to everyone. The recordings can be downloaded directly from the archive, but many listeners simply subscribe to the SRAA Podcast and receive each recording automatically, as it is published.

Turns out, the archive also attracts the interest of individuals outside of our radio world including historians, musicians, and filmmakers. Indeed, the archive has even been reviewed in The Wire Magazine by a music critic as an audio resource for electronic musicians. At time of posting, the SRAA is the inspiration for artists in the latest Cities and Memory project Shortwave Transmissions.

The archive is not, nor has ever been, monetized; it has no commercial sponsorship, and is completely funded by its contributors. It is free and open to everyone.

I’m exceedingly grateful to our many contributors who continue to unearth absolutely amazing off-air recordings. Our SRAA contributors are true champions of preserving our radio heritage in a space that will long outlast us.  We’ve taken measures to ensure that multiple archivists have full access to the site, so its existence isn’t dependent on any one individual. We also actively seek organizations and educational institutions who can house redundant copies of the Archive.

And still it grows.

Radio Spectrum Archive

Compared with the SRAA, the Radio Spectrum Archive (RSA) is still in its infancy.  But it, too, is growing, and the reason for this steady and growth is the existence of its contributors and other supporters.

Of course, while audio recordings––like those in the SRAA––are relatively small (often between 2 – 120 MB), spectrum recordings are larger by orders of magnitude.

As you might imagine–even in 2021/2022–it is not a simple task to digitally archive and share/move 20GB to 2 TB collections. We are incredibly fortunate in that the Internet Archive supports the RSA and gives us valuable real estate on their servers to preserve and share recordings.

With time, this collection will grow and become a resource for everyone. Our hope is that we may even be able to built a web interface (much like those used by Web SDRs) to play back recordings without having to physically download them.

My wholehearted thanks…

Of course, none of this would have been possible without the many contributors from within our radio community. Thank you all so much for being a part of a movement that archives our amazing, and amazingly diverse, radio history. You have made this possible.

Finally, I’m so grateful to the Radio Preservation Task Force––not just for this empowering partnership and what it means to us today, but for the future potential it represents.  It’s clear that we’ve only just begun.

Thank you––thank you––thank you, all.

SRAA: Remembering September 11, 2001 through off-air recordings

Today marks the 20th anniversary of 9/11; a day where we honor all of those who were lost, their families/friends, and all of those who who served during and after the attacks.

This morning, I’ve been listening to a number of off-air shortwave radio recordings made on September 11 and 12, 2001. Many thanks to the amazing contributors at the SRAA who shared these with us over the years. For this radio enthusiast, these recordings brings back memories even more vividly than video coverage.

Recordings:

If you have off-air recordings of 9/11coverage that you would like to share, please contact us at the archive.

Short recording of BBC World Service in DRM

Many thanks to SWLing Post contributor, Mangosman, who shares the following off-air recording via the KiwiSDR network and notes:

Attached is a diagram showing the path and the receiver data, the end of a one hour daily broadcast is in the other file. They switched the transmitter back to AM before the end of the station promo.

I listened to the same broadcast on the previous day. It did not have any disturbances over that time. The quality was identical.

That’s a great decode of the BBC in DRM. Thanks for sharing! DRM is such an amazing mode when you get consistent and stable reception. Here in North America, that can be very difficult to achieve, but it’s fascinating when it does happen! Thanks for sharing!

Five Beeps: Can you identify Carlos’ mystery signal?

Many thanks to SWLing Post contributor, Carlos Latuff, who writes from Brazil:

[Please check out this] audio sample of a signal I heard today (July 20, 2021) around 07h17 UTC on (at least) 4 different frequencies, simultaneously:

– 16166 kHz
– 16716 kHz
– 16747 kHz
– 16839 kHz

Always the same. Five beeps repeating in intervals of 30 seconds. 
Another mystery to be solved by your readers.

Thank you for sharing this, Carlos. Hopefully, a reader can comment and ID these beeps for us!
