The Mighty KBC broadcast again early this morning (from 00:00-02:00 UTC) on their new summer frequency of 9,925 kHz. Their signal from Nauen, Germany was packing 125 kW–it was amazingly strong into North America. As we’ve come to expect, the KBC’s Giant Jukebox of music has a lot of rock-n-roll and Euro-pop variety, spanning the decades; DJ, “Uncle Eric” knows how to entertain and spin the tunes!

You can listen to the full recording below in the embedded player, or simply right click this link and save the MP3 file to your computer:

You’ll notice that Kim Elliott has another installation of digital text modes in this broadcast. Decode these digital modes using Fldigi from www.w1hkj.com. Be sure to check out Dr. Elliott’s VOA Radiogram website for full details about this broadcast.

All Africa: Digital Did Not Kill the Radio Star

ChildSWRadioUgandaThis is a brilliant article on the importance and relevance of radio by David Smith with All Africa.  Below you’ll find some quotes, but it must be read in its entirety:

(Source: All Africa)

By David Smith

Radio threatens many of Africa’s big men.

Thugs working for Zimbabwe’s President Robert Mugabe have recently been confiscating and destroying receivers. Eritrea’s President Isaias Afewerki stopped issuing import licenses. Other iron-fisted rulers such as Swaziland’s King Mswati III and Sudan’s President Omar al-Bashir rarely hand out frequencies, thus reducing the range of independent radio.

The actions taken by these big men merely confirm radio’s supremacy in Africa. It may be old technology, but it is still relevant and appropriate. While not everybody owns a radio, most people have access to one.

[…]A number of radio stations based outside of Zimbabwe’s borders rely on reports from in-country correspondents who use mobile phones and the internet, particularly social media, to send their reports to distant studios.

[S]hort-wave has the advantage of sending signals over vast distances, irrespective of borders and local broadcasting restrictions.

[…]Zimbabwe is not the only country where short-wave is used to bypass restrictive broadcast legislation. Pirate, or clandestine short-wave stations, often staffed by members of the target country’s diaspora, use high-frequency transmitters to send uncensored programming to dozens of countries, including Libya, Madagascar, Sudan, Western Sahara and all the states in the Horn of Africa.

[…]Radios no longer simply transmit. They also receive. The convergence between these two communications devices has created a new community and international platform for lone, isolated voices.

The list of radio stations that do not have an SMS or social network relationship with their listeners, despite their location, is getting increasingly shorter. Any station that fails to interact with its public risks going the way of the dodo.

[…]Video and digital did not kill the radio star. Radio is stronger than ever in Africa, thanks largely to its ability to absorb and adapt to changing technology.[…]

Thanks to author David Smith and All Africa.

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.

Shortwave Radio Recordings: Rádio Nacional da Amazônia

Rio_de_JaneiroLast night, Rádio Nacional da Amazônia had a booming signal into North America on 11,780 kHz. Rádio Nacional’s AM signal was very wide; I actually opened up the filter on my SDR to 16 kHz to record this broadcast. In truth, that’s probably too wide, but it certainly made for great audio fidelity.

So, if you’re in the mood for some Brazilian music and commentary today, this 168 minute recording of Rádio Nacional da Amazônia should satisfy.

This was recorded on Sunday, April 28–starting around 22:15 UTC–on 11.78 MHz. Click here to download the full recording as an MP3 file, or listen in the embedded player below:

VOA Radiogram for April 27/28 includes Thor50x2, PSK63F, and Flamp

VOARadiogram(Source: VOA Radiogram)

Apologies for not updating this website since the April 20/21 VOA Radiogram. I have been diverted by deadlines connected to my other full-time job, audience research analyst for the International Broadcasting Bureau.

Thanks to all who sent reception reports, screenshots, audio samples, and other materials from the past weekend’s program. MFSK held off a challenge from the Thor modes and remains the most successful of the modes we have tested.

However, because your producer omitted the Thor 50×2 mode — a mode that might prove to be robust — from that program, VOA Radiogram on April 27/28 will include a “make good” transmission of Thor 50×2. And a transmission of Thor 50×1 for comparison.

There will also be a transmission of the PSK63F mode. This rather slow mode performed well during VOA Radiogram 1, but we only gave it a minute. There will be a longer transmission of PSK63F this weekend to allow a better evaluation.

The last text transmission this weekend will be in the Flamp format. If you don’t already have it, please download Flamp from www.w1hkj.com. Flamp divides a text file into several blocks, each with a specific number of characters. If any block is received without the correct number of characters, that block is rejected. The missing block can be picked up during the repeat transmission. Flamp might be useful for those text transmissions that are received at about 90% copy, when occasional deep fades prevent 100% copy. In Flamp, under Configure, check both of the Auto sync boxes.

Here is the lineup for the April 27/28 VOA Radiogram:

MFSK16 (58 wpm) program preview
PSK63F (55 wpm), 2:50
MFSK32 text (120 wpm) and image, 4:28
Thor50x1 (180wpm), 1:48
Thor50x2 (180wpm), 1:46
MFSK64 (240 wpm), 2:16
MFSK128* in Flamp X2 format, 3:46
MFSK32 image

*Probably a good idea to set the MFSK128 mode manually rather than depend on the RSID

All modes will be centered on 1500 Hz.

Each mode will be introduced by a brief MFSK16 transmission, same as last weekend.
