List price of Bonito 1102S RadioJet for US

Universal Radio has published the “List Price” of the Bonito 1102S RadioJet at $784.00 US.

This could make the RadioJet a very strong competitor to other SDRs on the market in North America. The list price (not necessarily the final price Universal will announce–which could be lower) is $216 less than that of the Microtelecom Perseus ($999.95 US) and the $116 less than the WinRadio Excalibur ($899.95 US).

After reading Fernando’s review of the RadioJet–where he compared it to the Perseus–this may be one of the best SDR performers for the price. We will be reviewing the Bonito 1102S RadioJet in the near future as well.

CDNSE Newstar DR111 First Review

The DR111 DRM Radio (Photo: Chengdu NewStar Electronics)

Based on this initial review, it appears that the CDNSE Newstar DR111 is an improvement over the company’s last portable DRM radio, the DiWave.

[T]he unit is quite sensitive. RNZI evenings at 17675kHz and 13730kHz can be received various places within my house with only the internal whip. REE at 9630kHz using an external ham vertical antenna was similar copy on Pappradio (with a slight edge given to the Pappradio.)

DRM Audio while adequate, seems narrow and compressed in comparison to DReaM on my PC. I verified this by switching A to B between the Newstar and the Pappradio with DReaM using my JBL headphones. I’m beginning to wonder if the DRM audio is being processed by the DSP, just like the analogue audio. The DSP in analogue is a tad too aggressive. A real bonus in analogue is the adjustable bandwidth (1-6kHz) however. That and the DSP make analogue quite enjoyable even in the crowded 49M (6MHz) band. I have been listening to BBC on 5875kHz in the early AM with armchair copy and great audio using only the whip (throughout the house).

China blocks foreign websites for one hour

China’s internet users have been cut off from accessing all foreign websites for around an hour in an unexplained incident that sparked speculation the country’s censorship system was being tested or further tightened.

The “great firewall” already blocks many sites hosted from other countries, but users in Beijing, Shanghai and other parts of China reported that they could not reach any foreign sites whatsoever on Thursday morning – although it was not clear whether the problems were universal.

Meanwhile, users abroad and in Hong Kong – which is part of China but not subject to Beijing’s net censorship – said they were unable to reach any sites on the Chinese mainland.

Some believed it was purely a technical failure, with several suggesting that Wednesday’s massive earthquakes had hit an undersea cable, disrupting services. In 2007, a tremor hit a major cable and dramatically slowed access to overseas sites for months.

Xu Chuanchao, an executive at Sohu, one of the country’s biggest internet portals, wrote on his microblog: “This malfunction is caused by the failure of China’s backbone network and is under renovation.”

But one company, Data Centre for China Internet, posted: “Latest news: most foreign websites can’t be accessed. Analysis: for commonly known reasons, a large number of foreign URLs are blocked. It is possible that the great firewall is undergoing some readjustment, mistakenly adding many foreign websites to the blocking list. The details are unclear.” (Continue reading article…)

What is clear is that we know China actively blocks foreign websites that criticize their government. The Chinese website of the Voice of America and Radio Canada International have been blocked for years. China also censors search engine results.

I believe this incident was most likely a fault in their “great firewall” rather than any network backbone. International broadcasters should take note: as you pull shortwave services targeting China, how will your audience there hear you?

The Gazette: CBC cuts gut cherished international service

More attention to the cuts at RCI from The Gazette of Montreal. This article features quotes from my friend, Sheldon Harvey of the CIDX and the International Radio Report:

(Source: The Gazette)

MONTREAL – Lost amid the auditor-general’s report last week on the F-35 fighter planes and Canada raising the retirement age to 67, was news of the impending demise of Radio Canada International – the CBC’s international service, for many a lifeline to Canadian culture and politics, from as far away as Hanoi or Rio de Janeiro.

While CBC, like other crown corporations and government departments, has to cut 10 per cent of its overall budget as a result of federal cutbacks, RCI, which is administered by the CBC but has long been its poor cousin, was told more than 80 per cent of its budget would be slashed, or $10 million of $12.3 million.

[…]“Upsetting,” “absolutely dreadful,” “shocking.” Those were the words listeners from Bulgaria to Missouri used to describe the end of RCI’s shortwave broadcasts after more than six decades on the air.

[…]Sheldon Harvey, the president of the Canadian International DX Club, and a longtime shortwave enthusiast, said the international service, over the decades, has gained a stellar reputation, ranked just behind the BBC World Service – despite its relatively tiny budget – for its balanced, neutral perspective.

It was never a propaganda tool, like the Voice of America, he said.

“They have table scraps thrown at them, yet are able to put together such high-quality broadcasts for people around the world,” Harvey said. “To see that tossed aside is really sad.”

[T]he idea that listeners in other countries can all go online is farcical, Harvey said. Only 22 per cent of the population in the developing world has access to the Internet, whereas anyone with a wind-up or solar-powered radio can receive shortwave transmissions. What’s more, governments can block the Internet – as they have in Iran, China and parts of the Arab world – all part of today’s Iron Curtain. But as was seen during the Cold War, it’s almost impossible to block shortwave frequencies. If the Soviet Union jammed some frequencies, broadcasters could simply switch to others, Harvey said, and the cat and mouse game continued.

Up till now, RCI also has served to introduce people to Canada during peacetime, whether as potential visitors, trading partners or immigrants, Harvey said. Shutting down its broadcasts is like closing down embassies and trade missions. “It’s waiting for people to come to us, as opposed to knocking on their doors … I don’t think the government realizes how much of the world they are cutting off by doing this.”

[…]“CBC’s mandate is to inform Canadians. But it’s important to have a broader perspective here. … If you believe this country has something to say, you can’t support these cuts.”

Censorship in Djibouti: International broadcasters, take note

1 Reply

I just caught wind of a now all-too-familiar story in international broadcasting–this time, via Reporters Without Borders.

While I encourage you to read the full press release below, the summarized story is that Reporters Without Borders has launched a mirror web site for La Voix de Djibouti, an independent news source in Djibouti. Why? Because the regime in power in Djibouti, in an effort to stifle the free press, have decided to block the primary website of La Voix de Djibouti.

The article states (we add the boldface):

A Europe-based exile radio station that supports the opposition Renewal and Development Movement (MRD), La Voix de Djibouti, began by broadcasting on the short wave and then switched to being a web radio, but the authorities have blocked access to its website from within Djibouti.

The decision to move off of shortwave has, in essence, severely limited their freedom of the press and their listeners’/subscribers’ access to information. Reporters Without Borders is addressing this censorship by actively creating mirror sites of La Voix de Djibouti that are hosted outside of the blocked domains.

This is admirable, and we strongly support their worthy efforts in creating mirror sites. However, this solution is, at best, full of holes:

How do those who wish to follow the news find each new mirror site after it has been blocked? And presuming they can do so, how long will this take to figure out?
Will the website reader be tracked by the government and/or punished for attempting to circumvent imposed blocking? (Hint: Most regimes now have tools to do this: read this and this.) Has anyone considered these consequences to any individual caught for circumventing a blocked site?
What if the regime decides to simply turn off the internet? Can they do this? Sure they can…and frustratingly, they may.

As we’ve stated here many times before, the Internet is a wonderful information resource and it is proliferating across the planet. But with the Internet, as with FM radio, cable TV and terrestrial TV, repressive regimes can and do hold the power button, as well as the ability to control the content, or even take it over.

Shortwave radio is comparatively immune to this, and moreover, is untraceable. When we eliminate the infrastructure that supports shortwave broadcasting (as is happening at RCI Sackville) we are throwing the baby out with the bathwater.

Poor child.

(Source: Reporters Without Borders)

4 April 2012–Reporters Without Borders has today launched a mirror site of radio La Voix de Djibouti’s website, http://lavoixdedjibouti.com, in order to help circumvent the government’s censorship and allow the population to have access to a news sources to which it is being denied.

The media freedom organization invites Internet users to go to http://lavoixdedjibouti.rsf.org in order to access an exact copy of the original site.

“As this is a country without media freedom, where only government propaganda is tolerated, we think it is crucial to help the population to gain access to other news sources,” Reporters Without Borders said. “While it is true that the level of Internet use is still low in Djibouti, it is not negligible, and use of social networks in particular is growing. The population will now be able to read critical news bulletins online.”

A Europe-based exile radio station that supports the opposition Renewal and Development Movement (MRD), La Voix de Djibouti began by broadcasting on the short wave and then switched to being a web radio but the authorities have blocked access to its website from within Djibouti.

So that independent news websites that are targeted by cyber-attacks and government blocking can continue posting information online, Reporters Without Borders has started mirroring sites. The first sites to be mirrored were those of the Chechen magazine Dosh and the Sri Lankan online newspaper Lanka-e News. The organization has also been urging Internet users all over the world to create more mirrors of these sites in a chain of solidarity.

Mirror sites can be used to circumvent blocking by governments. Although the government of Djibouti is blocking access to La Voix de Djibouti’s site, http://lavoixdedjibouti.com, by blocking the site domain name or the hosting server’s IP address, Internet users can still access the Reporters Without Borders mirror site, http://lavoixdedjibouti.rsf.org, because it is hosted on another server with another domain name.

The mirror site will be regularly and automatically updated with all the new content posted on the original site. If the mirror is itself later also blocked, the creation of further mirror sites together with a regularly updated list of these mirrors will continue to render the blocking ineffective in what is known as a Streisand effect.

Reporters Without Borders urges Internet users who want to help combat censorship and have the ability to host a site on a web server to follow suit. Send the URL of the mirror site you have created to wefightcensorship [at] rsf.org. The next mirroring operations launched by Reporters Without Borders will be reported on the @RSF_RWB and @RSFNet Twitter accounts with the #RSFmirror hashtag.
