Shortwave Radio Recordings: Radio Australia

CRI-bandwidthLike most Friday mornings, yesterday at 11:00 UTC, I tuned to 9,580 kHz to listen to Radio Australia news and ABC National’s technology program Download This Show.

While the signal out of Shepparton, Australia was as strong as ever, I heard adjacent interference from China Radio International.

Indeed, looking my WinRadio Excalibur‘s spectrum display (see image on right), you can see that CRI’s signal on 9,570 kHz was actually producing noise 15 kHz on either side of their AM carrier (for a total bandwidth of 30 kHz!). Radio Australia’s signal was much cleaner, sticking to their allotted 10 kHz bandwidth limit.

The recording of Radio Australia was still quite good, despite the interference, because I was able to run the Excalibur’s AM sync detector locked on the (less noisy) upper side band.

All India Radio publishes a tender for 800 DRM receivers

drmlogoThe DRM Consortium has posted an All India Radio (AIR) tender for 800 DRM AM/FM/Shortwave receivers.

AIR is seeking a DRM receiver with a feature set that would include:

  • DRM decoding on both shortwave and medium wave (AM broadcast) bands
  • 1 kHz tuning increments on DRM bands (with DRM auto lock)
  • Stereo speakers and headphone jack
  • Four line mono/color digital display
  • Built-in stereo recording of DRM broadcasts–including a scheduling feature
  • Upgradable firmware
  • Built-in rechargeable battery pack with 6 hour playback time

There are more specs/features, of course–click here or here to download a scanned copy of the actual AIR tender.

Document radio interference via the Ofcom Spectrum Management Survey

PLT devices can produce broad spectrum noise on the shortwave/amateur radio HF bands

Nige (G7CNF) recently contacted me regarding a survey he has created to help document and fight radio interference from power line technology and other sources.

If you live in the UK and can create an Ofcom case reference number, please consider contributing.

I have created a new forum (or rather relaunched my old one but with some rebranding) […] dedicated to discussing and curing [radio] interference.

I was contacted recently on one of my PLT YT videos by a SWL who was suffering PLT interference and it reminded me that since 2010, SWLs have had no ‘right to complain’ in the UK after Ofcom delegated domestic broadcast interference to the BBC. Frankly I think that is unacceptable and I want to address that imbalance.

I have created a new survey, the ‘Ofcom Spectrum Management Survey.’ Unlike the previous incarnation which was aimed at radio amateurs alone, this time I have opened it up to all radio users, regardless of type; the only qualification needed to fill this survey is an Ofcom case reference number. […]

Like the RSGB noise floor monitoring campaign which has just been stepped up to incorporate the use of the Cross-Country-Wireless Sentinel SDR noise monitor, I believe that my Ofcom survey will offer insights into the regulator’s performance over over time – and highlight its deficiencies by placing Ofcom spectrum abuse cases in the public domain.

Many thanks for your time and the best of luck with the hobby.

Nige, thank you for organizing this survey and campaign–best of luck moving forward!

The BBC has today announced development of a brand new news programme, Outside Source, hosted by Ros Atkins, to be broadcast across its international platforms – BBC World Service Radio, BBC World News TV and BBC.com.

This innovative new show will link the BBC’s global network of journalists with a worldwide audience using the latest in broadcast technology.

Broadcasting live from the BBC’s new state-of-the-art newsroom in the redeveloped Broadcasting House, London, the programme is launching initially on World Service Radio. It is then planned to develop the format to provide audiences with a fully integrated web, radio and TV experience.

Outside Source aims to open up the news process, enabling people to discover the latest on the stories that matter to them. An hour-long World Service Radio show is the first element of the pan-Global News format to be brought to air. Outside Source will be broadcast weekdays between 11am and 12pm GMT.

The programme will then be developed to include an online element, encouraging audiences to share their knowledge and experience of that day’s stories, no matter where they are in the world, via social media.

The online roll-out will be followed by the TV offering, due early in 2014 – a half-hour programme on BBC World News, the BBC’s international 24-hour television news channel – broadcast in the early evening GMT.

Using the latest technology means, Ros won’t be tied to a studio for the live broadcasts. He’ll be moving around Broadcasting House so listeners are getting the latest information on stories from our reporters, whether they are in one of the 27 language services or part of the BBC’s team of correspondents. Plus there will be ample opportunity for the audience to comment and add insight about stories happening where they are.

Sharing the ethos behind Outside Source, Editor Mark Sandell comments: “Outside Source is an exercise in open journalism. It aims to open up the news process and involve the audience in understanding the news. It will be technologically advanced and ambitious but also transparent and accessible. We want it to be ‘in the moment’ as we and the audience are discovering the news.”

Introducing the new programme, Ros Atkins says: “We are all incredibly excited about the new show. Such an innovative programme is only possible because of our new facilities here at Broadcasting House. While our starting point will be the expertise we have in the building, such as our language services and our bureaux teams, we’ll also be using social media and story communities to complement what we are discovering and to find out what our audience is making of the news. Outside Source will show we really are the world’s newsroom.”

Outside Source will launch first on BBC World Service on Monday 28 October at 11am GMT weekday mornings.

With the FCC in shutdown, pirates hit the air

pirateI noted at least seven pirate radio loggings here in North America on Wednesday, October 1–the first day of the US government shutdown. This is a remarkable number of pirate loggings for a weekday night.

I then saw a message from Ragnar Daneskjold, pointing to the FCC’s printed plan for an “Orderly Shutdown Due to Lapse of Congressional Appropriations” and this quote, in particular:

“FCC activities other than those immediately necessary for the protection of life or property will cease.”

So I’m sure, as one SWLing Post reader pointed out, pirates will “play while the (FCC) cat is away.”

During the US government shutdown, expect extra pirate activity weekday nights between 6920-6970 kHz.

US Shutdown: AFN Diego Garcia reduces broadcasts

AFN-Diego-GarciaThe American Forces Network’s Pacific transmitting site, Diego Garcia, will have reduced radio broadcasts due to the US government shutdown. The following is a statement from their Facebook page:

“In light of the government shutdown, because of mandatory staff reductions at the AFN broadcast center, AFN will reduce television services to the news and pentagon channels only. AFN radio will carry some football games live on the voice. We’ll keep you updated as the situation progresses.”

AFN Diego Garcia broadcasts on 12,579 kHz and 4,319 kHz . Many thanks to Sudipta Ghose for the tip!
