AOR introduces the AR6000: the 40 kHz to 6 GHz receiver

The AOR AR6000

The AOR AR6000

AOR has announced their latest (very) wide band receiver, the AR6000 last month at the 2013 Dayton Hamvention.

As with most AOR equipment, the AR6000 comes at a premium price–$6,500 US–but this receiver is quite unique in that it covers most of the radio spectrum 40 kHz to 6 GHz. I imagine AOR sells most of these to commercial and government entities; indeed it’s only available for export or government purchase here within the US.

Details below:

The AR6000 delivers continuous tuning from 40 kilohertz to 6 gigahertz in a wide variety of modes for professional monitoring performance that’s nothing short of amazing in terms of accuracy, sensitivity and speed. Standard modes include AM, FM, WFM, FM Stereo, USB, LSB and CW. An optional module can add the capability to receive APCO25 digital communications plus an optional I/Q output can be added to capture up to one megahertz of bandwidth onto a storage device for later listening or signal analysis.

Designed for the monitoring or technical service professional, there are no interruptions in the AR6000’s tuning range. With exceptional tuning accuracy and sensitivity throughout its tuning range, the AR6000 begins at the floor of the radio spectrum and continues up through microwave frequencies so it can be used for land-based or satellite communications. It works as a measuring receiver for those seeking a reliable frequency and signal strength standard. To support its broad spectrum, the AR6000 has two antenna ports, with the added capability of an optional remote antenna selector from the front panel of the receiver.

With its popular analog signal strength meter and large easy-to-read digital spectrum display, the AR6000 is destined to become the new choice of federal, state and local law enforcement agencies, the military, emergency managers, diplomatic service, lab technicians, news-gathering operations and security professionals

The new Tecsun R-2010D

TecsunR2010D

[UPDATE: Click here to read my full review of the R-2010D.]

I just ordered the Tecsun R-2010D–a SiLabs DSP-based shortwave radio with an analog dial and tuning mechanism–on eBay.

The Tecsun R-2010D is very similar to the Degen DE321, DE32 and the Kchibo KK-9803. I hold out hope though that the Tecsun will lead the pack of these small radios as Tecsun tends to do a better implementation of the SiLabs DSP chip.

Honestly, I had only recently decided that the R-2010 would never come to fruition.  I first was tipped off about it in 2009; then in 2011, a Tecsun representative told me that they were planning to re-design the R-2010. I suppose that’s how the R-2010D came about.

As soon as I receive this little radio, I’ll share my first impressions and a full review.

Thanks for the tip, Paul!

WiNRADiO introduces the Excalibur Pro WB (WR-G35DDCi): an SDR with 32 MHz bandwidth

The new WinRadio WR-G35DDCi will reecord 32 MHz of simultaneous bandwidth; in other words, the entire MW and HF bands.

Of course, you’ll need a Petabyte hard drive to store that data!

The Australian manufacturer WiNRADiO, well known for their pioneering work in the

field of software-defined radios, will be showing their latest new product development, the WR-G35DDCi, also called “Excalibur Pro WB”, as a world’s first at this year’s Ham Radio show in Friedrichshafen, Germany. This direct-sampling shortwave
receiver with a tuning range from 9 kHz to 45 MHz boasts a real-time processing bandwidth of 32 MHz, the world’s widest for a receiver of this class. This is further matched by other excellent parameters such as high frequency stability (0.5 ppm),
superior dynamic range (107 dB), excellent sensitivity (0.10 ?V) and very high IP3 (+31 dBm). Also on offer is a 45 MHz wide real-time spectrum analyser with waterfall display.

The “Excalibur Pro WB” comes as a PCI-e card, which is fully shielded for operation inside a computer, and employs a high-grade 16-bit 100 MSPS analog-to-digital converter, together with highly integrated FPGA circuitry. This combination enables
the WR-G35DDCi receiver to perform exceptionally well across an extremely wide range of signal levels and at the same time offer an instantaneous bandwidth of 32 MHz. The user can therefore continually process, record and replay the entire
shortwave band in real-time. The receiver’s robust front-end is equipped with an ultrahigh linearity amplifier which offers exceptional strong signal performance. This is further optimized by a switchable low-noise preamplifier together with a configurable multi-band pre-selector.

By employing innovative direct-sampling digital down-converter techniques and a choice of leading-edge components and design concepts, the WR-G35DDCi introduces numerous special features that are usually not available with other
receivers, irrespective of their price, including a suite of  measurement and test functions. There is also an external reference clock input and a FPGA interface bus provided, which allows this receiver to be used in advanced phase-coherent multichannel systems.

Amongst other special features, there are three demodulator channels, ranging in bandwidth from 1 Hz to 64 kHz each, which can operate concurrently within the 32 MHz wide DDC bandwidth. This allows independent and simultaneous
demodulation, recording and further digital processing within each demodulator, offering in essence three fully-fledged HF receivers within the one unit.

The WiNRADiO WR-G35DDCi will be available after the Ham Radio show, at a recommended sales price of Euro 4,197.50, plus any applicable local sales taxes.

The Gezi Park Protests: don’t look to the Voice of Turkey for information

On shortwave, sometimes it’s what’s not heard that speaks volumes.

Gezi protest in K?z?lay Square, Ankara (Source: Wikimedia Commons)

Turkey has been in the world headlines now for well over a week. In case you’re not up-to-date, here’s a summary of what has happened:

On May 28, 2013,  about fifty environmentalists led a small protest in Istanbul to oppose the replacement of Taksim Gezi Park with a reconstruction of the Taksim Military Barracks.  The protests escalated when the group occupying the park was attacked with water cannons and tear gas by the Turkish police. This event led to riots, which were soon widespread; the protests, meanwhile, broadened their scope into full-fledged anti-government demonstrations across the country and even into the Turkish diaspora across the globe.

Yesterday, I turned to the Voice of Turkey on shortwave radio to hear about the active protests currently ongoing throughout the country…

But what did I hear? The only mention I heard of the Gezi Park protests in the Voice of Turkey’s English language service were in a passing Turkish press report on the reaction to the protests by the US Secretary of State, John Kerry. The item, moreover, was completely buried in their broadcast and certainly not something upon which they elaborated in the least (listen, beginning at 12:50 below).

I’ve always loved listening to the Voice of Turkey, but events like this remind me of the simple fact that many international broadcasters are still very much the mouthpieces of their governments.

Of course, Turkey certainly would not win an award for press freedom; not even close. Reporters Without Borders list Turkey as a country with a “Difficult Situation” with regards to press freedoms, ranking them 154th out of 179 countries in their 2013 Press Freedom Index. To put this in perspective, Finland and the Netherlands occupy the top two spots as models of press freedom, the USA is number 32, and North Korea and Eritrea occupy the bottom spots (numbers 178 and 179, respectively) obviously countries without press freedoms.

I’d like to think that the news readers at the Voice of Turkey would rather give this news the attention it deserves, or at least offer the Turkish government’s perspective on the demonstrations. Instead, what we heard was…nothing.  And we heard that loud and clear.

Indeed, the world is paying attention to the lack of news coming out of Turkey right now. Time Magazine posted this article article yesterday, which begins:

As epic clashes between anti-government protesters and riot police turned downtown Istanbul into a battle zone last weekend, the country’s two main news channels had, well, not much to report. One ran a documentary on penguins. The other, a cooking show. To many Turks, their silence was symptomatic of the self-censorship Turkey’s media have practiced under Prime Minister Recep Tayyip Erdogan’s tightfisted 10-year rule. Penguin T-shirts, penguin jokes and penguin costumes now abound — the bird has become a symbol of protesters’ frustration with the mainstream media.

VoiceOfTurkeyOne of the most amazing things about shortwave radio is that by really listening, you can hear the unfiltered voices of regional broadcasters, the clandestine organizations, and the media representatives of their respective countries.

If this story had broken twenty years ago, moreover, I would have heard it as a headline from every respected international broadcaster. Then, upon turning to the in-country “news source,” as I attempted to do yesterday when I tuned in the Voice of Turkey and was subjected to a total lack of news, I would therefore be instantly made aware of what the Turkish government didn’t want me to hear.

Unfortunately I feel we’ve lost a bit of this comparative news consumption, not just because of the exodus of many trusted radio broadcasters from the field, but because we’ve been trained to consume news in (palatable) bites. Our attention spans and interest seem to have diminished to the point that we now often rely on our news sources to interpret for us.  A sad fact…especially considering politically-evolving countries like Turkey still need our attention, interest, and thoughtful support.

SWLing Post Readers,

I am very happy to announce a project to share and archive our shortwave radio recordings: The Shortwave Radio Audio Archive.

Many of you probably already know that I believe archiving our shortwave radio broadcasts is vital now.  Many broadcasters are leaving the air, and many target areas are being removed altogether. Meanwhile, over the past two years there have been new broadcasters coming on the air, often doing test transmissions before beginning broadcasting in earnest. These, too, are significant in radio history.

I have already populated the site with more than eighty recordings, most of which I’ve posted here over the past two years. I still have thirty or more to add. Already in the archive: Radio Bulgaria (now silent), Radio Netherlands Worldwide, The BBC WS special broadcast of the Diamond Jubilee, and a very interesting Vatican Radio broadcast announcing the selection of the new pope.

If you subscribe to the SW Radio Audio Archive’s podcast, you’ll be able to see and download the entire existing collection and new recordings as they are added.

To make this project work, we need your participation!   You can help in two ways:

  1. Share your shortwave radio recordings! Simply create an Archive.org account, upload your recording, and share the link with us (we have a nifty web form for submissions). Full details are available on this page.
  2. Simply subscribe to the podcast, download the recordings…and save them.  By doing this, you’ll be making an archived copy of all of the recordings. Here are two ways to subscribe to the podcast:

Donations and radio-related, commercial sponsorships are also welcome.

On the site, we state that “Multiple archives in multiple storage locations ensure the integrity of this collection over time.”  This is very true of all archives: the more forms of back up, the better. Especially since archive-quality digital storage does not yet exist. Safety and integrity come with redundancy.

Remember, this project is a collective, community effort, so I hope you will consider sharing your recordings with the rest of the world!

Feel free to share this post and the site http://shortwavearchive.com via social media, your radio groups and message boards. Thank you!
