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.”

FCC: A detailed application for a new 10KW DRM transmitter

Many thanks to SWLing Post contributor, Ed, who writes:

Thomas, did you see this? It’s a detailed application to the FCC for the construction of a 10KW shortwave transmitter for DRM on 9.65 MHz and 15.45 MHz.

Click here to download the application (PDF).

Thanks, Ed! I know nothing about Turms Tech other than on their FCC application, they list their business is “broadcast and data.”

Another SWLing Post reader forwarded the following from this article in Radio Mag Online:

“Of interest in the U.S. is the recent application of Turms Tech LLC to broadcast DRM from New Jersey toward Europe and the Middle East. Specifically, they plan on using the Armstrong tower, just west and north of New York City, with yagi-type antennas, generating an ERP of 10 kW on 9.65 and 15.45 MHz.”

The Radio Mag article is worth reading in full as it includes a number of DRM news items.

CDNSE Newstar DR111 First Review

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).

Could the DR111 DRM Radio be the portable we’ve been waiting for?

One of the reasons DRM (Digital Radio Mondial) has struggled to gain global popularity is that there has yet to be a portable radio solution with universal appeal.

Perhaps the future Chengdu NewStar Electronics DR111 DRM Radio will change that? According to their website, the company is certainly setting out to make an affordable receiver that is simple to operate. Hopefully, CDNSE has learned from this radio’s predecessor; ergonomics, affordability and overall ability to receive and decode DRM signals are the keys to its success.

We have added the DR111 to our Shortwave Radio Index. Check back as we will post updates.

Modify a Realistic DX-394 for DRM

Do you have a Realistic DX-394? If so, you can modify it to become a DRM (Digital Radio Mondial) receiver. Simply follow these very well documented instructions.

Thanks to Mike on the DRMNA email list for bringing this cool mod to my attention.
