International Day for Disaster Reduction 13th October

On Friday 13th October, the United Nations Office for Disaster Risk
Reduction, explores how communities around the world are reducing their
exposure to disasters. In a recent blog “When digital is more than
just radio”, the DRM Chair, Ruxandra Obreja, outlined the considerable
benefits to be realised if Governments and manufacturers were to fully
exploit the emergency warning feature embedded in DRM and digital
radio technology. Read more.

Digital Radio Mondiale Delivers at IBC 2017

Participants in the four DRM events organised at IBC by Gospell, Thomson Broadcast, Nautel and Ampegon between 15th-17th of September have had an insight into a wide range of DRM activities, from big projects in Morocco (Thomson Broadcast), India and Hungary (Nautel), to the progress of DRM in South Africa. And DRM used not just for broadcasting but for other vital activities was demonstrated by Rfmondial involved in a wide-ranging application for the US Coast Guard.

One constant for all events, each unique and so different from the other, was the positive messages about DRM in both AM and VHF and the increasing availability of new receiver and receiver solutions, many always on display. The first event on Friday the 15th (Gospell) saw the launch of GR-227 the multi-standard (DRM/DAB/DAB+) car adaptor that is compatible with any car stereo with USB port and able to work with Android Smart Tune App. As the manufacturer explained, this after-market solution can be a significant development allowing digital reception in cars initially fitted with analogue receivers.

Of equal major interest was also the Titus II multi-standard digital radio receiver produced by Titus SDR, a division of PantronX. The consumer software-defined radio digital receiver platform, which is the result of collaboration between Titus SDR/Patron X, Jasmin-Infotech, TWR, and Fraunhofer IIS, supports multi-standard radio reception, including DRM, DAB and DAB+ and core data applications. The representatives of PantronX and TWR received lots of questions about this receiver system based on a custom Android tablet platform, featuring multipoint touch, WiFi/Bluetooth and stereo sound.

Other receiver possibilities: the tablet solution presented by Fraunhofer IIS, the Indian receiver Avion, and a new concept DRM receiver produced in South Africa all enforced the idea that the excellent work done by transmitter companies like Thomson Broadcast, Nautel and Ampegon in providing a digital transmitter infrastructure in many parts of the world can link now with the innovative receiver solutions.

The Thomson event came alive with the presentation about the huge project in Morocco and the Nautel event attracted lots of guests already familiar with the big projects of this established transmitter manufacturer recently in India and now in Hungary.

The last of the DRM events, hosted on the 17th by Ampegon was a moment of celebration. First of this company (now 75 years old) displaying solid-state transmitters of all capacities successfully used globally, as well. As Ampegon has been also involved in Africa and supported the first DRM trial in South Africa two years ago, they were the natural hosts of a special DRM award moment. The DRM Enterprise Award 2017 (Africa) has been awarded to 3 pioneering experts in promoting DRM digital radio in South Africa. The winners are Dr Roelf Petersen on behalf of Radio Pulpit (member of the Pulpit Media Group) and Broadcom International involved in the trial of DRM in mediumwave. The other two winners Thembeka Khaka (Thembeka Khaka and Associates) and Johannes von Weyssenhoff have been very active in getting the legal framework and conducting the current trial (DRM for local coverage) that is taking place in conjunction with a community station in Johannesburg. (This event was streamed on Twitter click here to view.)

As Ruxandra Obreja, Consortium Chairman, remarked: ”All those who have hosted successful DRM events, the new and old supporters and specialists interested in digital radio and DRM, all the other companies supporting DRM and present at IBC (BBC, Babcock, Becil, RFI, Riz, NXP, Rfmondial, Sentech, to mention just a few) all the guests from countries as far apart as India, Argentina, the Netherlands, Belgium, Pakistan, the Philippines have seen how much effort goes so that DRM can deliver for all, globally.”

The GR-227: Gospell introduces a new SDR digital radio car adaptor

Many thanks to SWLing Post contributors Ed and Richard Langley for sharing information about the latest receiver from Gospell: the GR-227 digital radio car adaptor.

According to Radio World:

[…]The compact GR-227 can be added to car stereos, via a USB cable, in order to receive digital radio programs and corresponding data. Based on software-defined radio technology and using the xHE-AAC audio codec, the GR-227 is compatible with both modes of the Digital Radio Mondiale standard as well as the DAB/DAB+ digital radio standards.

According to Gospell, the GR-227 works with car stereos that are fitted with a USB port. Using the firm’s patent-pending technology, the adaptor behaves like a thumb drive when plugged into a USB port, making it compatible with most in-car receivers.

In addition, the GR-227 also features the Gospell Smart Tune App for Android. When partnered with an Android-powered car stereo, this lets users play back the broadcast audio program or benefit from data services.[…]

Read the full article at Radio World.

Richard comments:

“They call it an adaptor but perhaps it’s just an Android-controlled SDR receiver supplying audio output via a USB port, which could be connected to a computer or any other audio device with a USB audio input capability.”

I think he may be correct in that assumption because it may be the only way to get cross-manufacturer compatibility in a device like this.

The product information sheet noted that the receiver is supplied with a “triple band active antenna.” No doubt, the GR-227 will require adding a small external antenna to your car.

Still: an interesting product for sure! Perhaps the price point will be more reasonable that of previous DRM receivers? We’ll post updates from Gospell with the tag: GR-227

North Korea now broadcasting in DRM

Many thanks to SWLing Post contributor, Mark Fahey, who writes:

A message to contacts in North Asia (Japan / Korea etc)…

North Korea is currently (right now 1430UTC) broadcasting in DRM format on 3560KHz. Listening to remote receivers in Japan I can see the signal is very strong in the Tokyo and Yokohama areas – I assume it will be strong in other parts of Japan as well. I have NOT been able to decode the DRM successfully, I have tried piping the audio to me here in my Australian location and demodulating it with a software DRM decoder – I just can’t get a lock on the signal. Do you have a DRM receiver – could you please try? If you do manage to receive the signal please don’t forget to record it!

I’m particularly interested to know if the transmissions are relays of KCBS Pyongyang, Pyongyang Pangsong or some other service. If you get a demodulated signal could you check to see if the program is parallel to KCBS Pyongyang on 2850KHz or Pyongyang Pangsong on 6400KHz.

I have a WinRadio Excalibur with DRM here in Australia, but the signal is very weak here – far too weak to lock.

Later, Mark shared the following video by “2010DFS” on YouTube:

Mark also notes that DRMNA.info is following this story very closely and suspects that the content server and or transmitter may be Chinese in origin:

NOTE: Same frequency and bitrate as the 2012 broadcasts so this may represent “Chinese assistance”. Can anyone confirm DRM equipment in Kujang?

20170902 Update: I have received anonymous details that indicate that at least the content server is of Chinese origin. Still no word on actual transmit location. Several other Japanese (and Terje in Japan) have successfully decoded these transmissions.

Click here to read full details at DRMNA.info.

Being a North Korean propaganda specialist, Mark added:

At the Freeman’s Reach monitoring station the bandwidth and microwave paths in are really being tested this afternoon with the full on activity.

All plans for the afternoon and evening now cancelled! YTN (South Korea) via Intelsat, KCTV Pyongyang via Thaicom, CNN International via Foxtel, CNN USA Domestic via Sling, Korean Central Radio and Pyongyang Pansong via KiwiSDRs – Busy!

All spectrum being captured, tonight the servers will be working hard, it will keep this place warm!

Post readers: please comment if you’re able to decode any of these North Korean DRM transmissions, and/or if you have further information about these DRM broadcasts from North Korea.

UPDATE: Mark has at least confirmed that the DRM signal is a relay of the KCBS Pyongyang national service (domestic) broadcast.
