Radio Panik injects shortwave audio into mixes

LetrangerI 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

CBC-RCI-HearingLast 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.

RCIFor 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

WinRadioExcaliburFullScreen 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.

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.
