Radio Panik injects shortwave audio into mixes

1 Reply

I recently discovered that the radio show L’etranger, on Radio Panik, 105.4 in Brussels, used shortwave radio recordings of pirate radio and numbers stations, from the SWLing Post and other sources, in one of their mixes of eclectic music and sound clips.

The end result is a splendid piece of sonic art.

Note that their audio is only available on archive.org until May 23, 2013. Click here to download the show, or listen via the embedded player below. You can also hear the show on the L’etranger website.

Thoughts after the Canadian RCI/CBC Senate hearing

4 Replies

Last night, I listened to a live stream of the Canadian senate hearings regarding last year’s Radio Canada International cuts to shortwave radio. CBC president Hubert LaCroix and RCI director Michelle Parent met remarkably little criticism or resistance in the hearing, and it appears the report to the senate will be nothing short of cheerleading for the CBC. Indeed, the hearing’s tone overall was one of self-congratulation.

The decision to cut RCI in this manner is a prime example of a few officials with all-too-limited knowledge making decisions in the absence of experts’ input. The business decision seemed to them essentially sound, and yet the impact of the decision has far-reaching negative consequences–for Canadians and as well as the rest of the world–that these officials may never fully comprehend.

Notes from the hearing:

All but one senator patted CBC and RCI management on the back for becoming more innovative in the wake of devastating budget cuts; only one suggested that such innovation could have been achieved prior to them
No one asked if the CBC explored the possibility of scaling back shortwave services without closing the Sackville, NB transmitter site and eliminating shortwave broadcasts altogether, which would have been a much better use of funds as well as maintaining foreign relations and domestic security
Hubert LaCroix basically suggested that people living in oppressed regions could gain access to RCI via mobile platforms (sadly, this is not the case)
When asked how cuts to shortwave have effected their listenership and demographic, LaCroix basically shrugged his shoulders and pointed out how difficult it is to judge how many people listen on shortwave. (My response: What areas of our world lack a power grid infrastructure? Fully 1/4 of our planet. These are the underserved who rely heavily on shortwave)
No one inquired about the impact upon their Chinese audience, as RCI’s website is blocked in China; meanwhile, shortwave continues to be comparatively impermeable to firewalls and is untraceable in restrictive countries

Monsieur LaCroix made it clear that the primary CBC mandate is to be a creative, innovative media force within Canada. For him, and most of CBC management, Radio Canada International must have felt like a leech to their dwindling budget. Were I in his position, with limited information and a mandate to protect his main “client” set (Canadians living in Canada)–I might have made the same decision. And yet…it was the wrong one.

What would have solved the problem in the first place? Radio Canada International should have been its own entity, with its own budget to manage, however modest–and if anything, funded through the foreign office rather than the domestic public news/entertainment body. After all, what RCI accomplished on shortwave was far more humanitarian and diplomatic in nature.

I’ve written at length about the RCI cuts and will not go into them further on this post. But I do believe RCI Sackville could have been a more efficient and productive operation if it employed some sensible changes. Sackville had just finished installing a (paid-for) technology infrastructure to remotely operate the entire transmitter site. Moreover, Sackville management told me they had planned to cut their staff to a skeleton crew (of three people, if memory serves), only to be there if something mechanical on site needed service. These new adjustments were not even tried.

Additionally, using a market model, RCI/Sackville could have offered their relay services to more broadcasters at competitive (even market) rates. Their hourly rate to broadcast on shortwave was simply too high, thus potential customers sought more efficient cost-effective transmission sites. Sackville was never given the tools to become a self-funding operation like so many private broadcasters have become.

Sackville’s infrastructure was an incomparably valuable resource in which many millions in taxpayer money was already invested and paid in full; sadly, these cuts have destroyed this investment. The Sackville site, moreover, had the potential of a sleeping army, both in foreign affairs…and in Canadian security. But it’s gone. Simply because a few politicians doing their near-best didn’t have all the relevant information.

For what it’s worth

RCI still has some great talent on board. Canadian expats living abroad, and those who are connected to the web, can still enjoy RCI via the website or on mobile platforms. That is an audience that may actually expand through a social media presence–something they could have done more effectively prior to the budget cuts last year.

I was also encouraged to hear that there is a serious effort to distribute RCI’s online audio content–free of charge–to broadcasters in local radio stations around the world. This is very positive: FM, though not as accessible as shortwave in Africa, has a strong community following and stations are appearing everywhere. I hope RCI has a dedicated employee whose sole focus is to identify and build connections with these local outlets for their content.

Barring a takeover or drastic re-organization, it sounds like Radio Canada International over shortwave is now destined for the history books. To honor this history, I sincerely hope the new RCI innovates and penetrates new markets. And I hope RCI employees, many of whom have long memories, find challenge and renewed confidence going forward. We certainly appreciate all of the years during which they graced the shortwaves, and wish them all the best.

Confessions of an SDRaholic: when 4.5 terabytes is not enough

4 Replies

Alas, ever since I started using Software Defined Receivers (SDRs) last year, I’ve found that I fill up hard drives faster than I can buy them. As you may have noted, I like to make spectrum recordings–especially during the night-time hours, as I slumber. The following morning, upon waking, I’ll “tune” through, say, the 31 meter band as if it were live. What makes it even more amazing for me, is that I can fast-forward through time and scan for DX stations even more quickly. Great fun–highly addictive. And did I say, space-consuming?

On my WinRadio Excalibur, I find that I use about 4 gigabytes of hard drive space for a one-hour-long spectrum recording, 100 kHz wide. Of course, if I were to record a 2,000 kHz (2 MHz) chunk of spectrum, it would chew through 4 GB in, roughly, 3.5 minutes.

Fortunately, I rarely ever record spectrum that wide. I find that the maximum width I ever record is 1.25 MHz, which I reserve for occasions once in a blue moon. Most of the time, I stick to 100 kHz-160 kHz widths.

After I record a chunk of spectrum, I usually listen to it, create an AF recording of anything of interest, then delete it from my drive. You’d think this would effectively keep my hard drive cleared out, ready to receive the next installment? Not so. Well, at least, not in my undisciplined SDR beginnings.

The flaw in my logic

Quite often, I make spectrum recordings while traveling, and do so remotely (using TeamViewer to control my PC). In the past eight months, I’ve done a lot of traveling. When I return from a trip, I find that I’ve often amassed a sizable collection of spectrum recordings. Upon returning from travel I also find (not surprisingly) that I’m typically busier than normal, catching up with email, phone calls, and delayed appointments. Thus, I never quite get around to reviewing–and therefore deleting–these files. Most of the spectrum recordings taking up space on my internal drives are those I’ve recorded remotely.

Last year, I thought I’d solve the space problem on my ailing laptop by purchasing a dedicated tower PC (Core i5) maxed-out with RAM and with a 1TB internal (7200 RPM) hard drive. This particular Gateway PC also has a bay that accepts cheap internal SATA drives; I simply insert an internal SATA hard drive in the ejectable bay, load the drivers, and it’s good to go. When I purchased an additional 2 TB SATA drive for spectrum recordings, I thought I would be set for years to come…Ah, how the mighty crumble…

As I write this today, I find I only have a total of 350 GB available on my PC. I’ve also filled an entire 1.5 TB external hard drive with recordings I plan to archive and share with a fellow SWLer.

The Tandy Color Computer 2 (or, "CoCo 2") was my first personal computer. (Image: Wikimedia Commons)

My, how times have changed

Reverse to the 1980s: When I was ten years old, I thought my Tandy Color Computer 2 was the best thing since sliced bread. Its 16 kB was surely plenty of memory for whatever I wanted to do, and the cassette tapes I used as a form of external hard drive gave me the certainty of a virtually limitless supply of memory.

Today, I doubt I could make an intelligible MP3 recording, even with aggressive compression, that would fit a 16 kB file size.

Facing the truth

The frank fact is that I’ve gotten much better at managing hard drive space, now that I’ve been doing spectrum recordings for more than a year. I shouldn’t need to buy additional hard drive space unless it’s specifically for archiving/sharing purposes. I just need to regularly face the music (or static)–dig through spectrum recordings made last year, and delete those I no longer need.

How do I manage space now? Here are my tricks for staying on the wagon, and saving both space and time:

Use the minimum amount of bandwidth possible while making recordings
If possible, have your SDR parse files into 2GB chunks. This makes it easier to delete sections of recording that are no longer needed without having to delete the entire recording. Happily, the WinRadio Excaliber allows for this.
Each time you create a new spectrum recording, have it saved into a specific directory with a label that will help you identify the contents. For example, “Saturday Night Pirates” or “31 M Tues AM.”
Use Notepad or any simple text application and create a log sheet for the spectrum recording; make notes, then save it in the same directory as your spectrum recording.
When saving MP3/WAV files, use a standard file-naming convention to help you quickly ID a recording (you’ll notice all of my recordings do this). Mine follow this pattern: “StationName-Fequency-Date-StartingTimeInUTC.mp3” –e.g., “RadioAustralia-9580kHZ-05Feb13-1000Z.mp3”
Delete unwanted spectrum recordings as soon as you decide they are not worth keeping. If you wait a few days, you may forget that they’re okay to delete.
I also use my Bonito RadioJet for narrow IF recordings (of, say, one station). It allows me to adjust filters and “tune,” but takes very little hard drive space. The same can be achieved by narrowing your SDR spectrum width to 20-48 kHz.

Are you an avid shortwave/medium wave audio archivist (aka, audio addict)? What are your tricks of the trade? Please comment!

Boards Of Canada puzzle: shortwave numbers?

SWLing Post readers: I received the following email request today. Sounds fun and intriguing. Perhaps you can help solve this mystery…

Boards of Canada (Source: Last.fm)

Hello, readers of The SWLing Post, and please forgive the intrusion. I admittedly know very little about shortwave radio, but there has been a bit of a puzzle going on for fans of the band “Boards of Canada” recently, and there is the distinct possibility that its solution could involve shortwave radio. A message I posted over on Reddit was forwarded to Thomas, who very graciously offered to post the plea here.

Some background — Boards of Canada is an instrumental electronic music duo from Scotland who are, to put it mildly, somewhat private and aloof, in all the right ways. Their references tend to be very math-heavy and their music has some innovative and fascinating-sounding tape loops, synths, etc. This puzzle has been going on for the better part of a week, and we fans been very impressed with the complexity of it, though we are not even certain of the meaning of it — though we hope and suspect it is a lead-up to a new release by the band.

Someone (presumably the band) has been currently leaving these (for lack of a better word) “clues” in several key places in the media. First, a single album was sold to one person on National Record Store Day in the US — an album containing a “numbers station” style reading of a series of 6 numbers. Then a cryptic YouTube video with another series of 6 numbers also being read like a voice on a numbers station. 6 additional numbers were played (unannounced and without explanation) over a commercial radio station in England. Then on April 25, the band stealthily released 6 more numbers by encoding a link hidden in a gif — a link to two soundfiles that had to be played simultaneously in order to cancel out the phase and reveal — you guessed it — another numbers station-style broadcast.

We have reason to believe that there are 1 or 2 more series of numbers out there — and given the nature of the broadcasts, plus the picture of a radio tower on the band’s Facebook page and the different media by which the band has released some clues, there is at least some reason to believe that perhaps there is another series of numbers being broadcast somehow over shortwave radio.

Here is where I’m hoping the expertise of your readership might come in — as I say, I apologetically have no idea how the world of shortwave radio works. But I’m wondering: in your journeys across the frequencies recently, have any of you stumbled across anything that sounds like this:

http://youtu.be/Qe4UCjjyr8U — specifically something with that same chime pattern at the beginning and then the 6 numbers? (This is obviously not a “real” numbers station broadcast, but something made to sound like it). I would not put it past Boards of Canada to transmit a signal somehow and expect their listeners to find it.

And/or does this series of numbers mean anything to you in the shortwave world:

xxxxxx/628315/717228/936557/xxxxxx/519225

The Xs are gaps where we’re waiting to fill in the numbers, but we have yet to discover them — though one of the series might likely be 699742.

If you’re curious, here is a summary of most of the events that have happened so far: http://2020k.wordpress.com/2013/04/20/boards-of-canada-distribute-new-vinyl-releases-out-for-national-records-day/

Thanks so much, and apologies if this is a waste of your time — this may end up having nothing to do with shortwave transmissions — I just figured it might be worth a shot, and also an opportunity to learn more about this particular passion.

Numbers station HM01…and Ana Montes

7 Replies

Wednesday morning, I suppose I had number stations on the brain. It was no surprise, as I had just watched The Numbers Station the previous night. Nonetheless, I experienced a rather strange coincidence: I was reading an intriguing article about Ana Montes, “one of the most damaging spies in U.S. history,” when my shortwave radio–parked on 5,855 kHz–suddenly began to fire out an eerie series of numbers and data bursts from the Cuban numbers station, HM01. It was, unquestionably, the perfect accompaniment to the words I was reading.

A reader sent Montes’ story–written by Jim Popkin for The Washington Post Magazine–which made for fascinating reading. And as I read the account of Ana Montes’ rise in the ranks of the DIA, while simultaneously becoming one of Cuba’s most important spies, I remembered that it was actually Montes’ case that reader Dirk Rijmenants’ referred to in his paper, and that we posted earlier this year.

A “cheat sheet” provided by Cuban intelligence that
Ana Montes used to help her encrypt and decrypt
messages to and from her handlers. (Source: FBI)

Popkin’s account of Ana Montes’ life, character, promotions within the Defense and Intelligence Agency, and the sequence of events that led to her FBI investigation and imprisonment, are the stuff of spy novels. And of course, he mentions numbers stations:

[Montes’] tradecraft was classic. In Havana, agents with the Cuban intelligence service taught Montes how to slip packages to agents innocuously, how to communicate safely in code and how to disappear if needed.[…]

Montes got most of her orders the same way spies have since the Cold War: through numeric messages transmitted anonymously over shortwave radio. She would tune a Sony radio to AM frequency 7887 kHz, then wait for the “numbers station” broadcast to begin. A female voice would cut through the otherworldly static, declaring, “Atención! Atención!” then spew out 150 numbers into the night. “Tres-cero-uno-cero-siete, dos-cuatro-seis-dos-cuatro,” the voice would drone. Montes would key the digits into her computer, and a Cuban-installed decryption program would convert the numbers into Spanish-language text.[…]

On a side note, as Rijmenants points out, using a computer to decipher a numbers station was both unnecessary and risky.

The story continues:

Ana Montes

[…]On May 25, 2001, [an FBI team] slipped inside Apartment 20. Montes was out of town with Corneretto [her boyfriend], and the FBI searched her closets and laundry bins, paged through shelves of neatly stacked books and photographed personal papers. They spotted a cardboard box in the bedroom and carefully opened it. Inside was a Sony shortwave radio. Good start, Lapp thought. Next, techs found a Toshiba laptop. They copied the hard drive, shut down the computer and were gone.[…]The documents, which Montes had tried to delete, included instructions on how to translate numbers-station broadcasts and other Spy 101 tips.[…][…]Later that day, an FBI evidence team scoured Montes’s apartment for hours. Hidden in the lining of a notebook they found the handwritten cipher Montes used to encrypt and decrypt messages, scribbled shortwave radio frequencies and the address of a museum in Puerto Vallarta, Mexico, where she was meant to run in an emergency. The crib sheets were written on water-soluble disappearing paper.[…]

The story Popkin recounts, though, paints the picture of a very complex operative. One who, until discovered, was very successful at her craft. She pulled the wool over the eyes of the DIA and spied for the Cuban government for many years.

The story is complex, and Popkins’ account somehow maneuvers through the twists and turns.

If you want to experience what I did–if a little less coincidentally–click here to read Popkin’s full article, and meanwhile play this recording I made of the Cuban numbers station HM01, below:

Note that the year Montes listened to the Cuban numbers station on 7,887 kHz, it only contained numbers–unlike the recording here of HM01 (Hybrid Mode 01) which contains both voice and RDFT data bursts (which you can also decode, but not necessarily decipher).

This recording of the Cuban numbers station HM01 was recorded on April 24, 2013, at 10:00 UTC on 5,855 kHz in AM. Click here to download the recording as an MP3.
