Gospell in-car SDR DRM adaptor - GR-227

Here is a press release supporting the new product to be unveiled at IBC. Looks like another game-changer from Gospell. SDR for the car!

"Gospell announces the imminent release of GR-227 digital radio adaptor 
Chengdu, China, September 04, 2017  - A new adaptor  specifically designed for  in-car use  that simplifies digital radio on the road will be introduced at IBC by Gospell. 

GR-227 is a small, low-cost adaptor  that acts as an aftermarket add-on to car stereos receiving high-quality digital broadcast programs and data application, and serving it to the car audio system over a USB cable. Based on software defined radio technology, GR-227 is compatible with DAB, DAB+, DRM and is DRM+ ready. It is also powerful enough to support digital audio decoding such 
as extended HE-AAC (xHE-AAC).   

GR-227 literally works with any kind of car stereos with a USB port. Our patent pending technology allows the adaptor to behave like a thumb drive when plug into a USB port and makes it compatible with most of the music players not only in car but also for home use. 

To make the most of GR-227, the Gospell Smart Tune App for Android has been included to add more features. When partnered with an Android powered car stereo, the App not only allows for playback of the broadcast audio program but data application which brings much fun to car entertainment.   

By connecting the supplied triple band active antenna which can be attached to the windscreen through the SMA antenna connector, the reception in DRM, FM and DAB bands can be significantly improved, offering maximum flexibility between different broadcasting standards. 

Installing the plug-and-play GR-227 adaptor to your car is easy and doesn’t require changing your car  stereo. It  is one of the easiest ways to upgrade your car  radio  to digital without replacing anything. 

The Gospell’s aftermarket car adaptor range starts with USB model but more will follow to support more car stereo types. 

Haochun Liu,  DRM director, Gospell, said: “By leveraging SDR, we can now combine multiple broadcasting standards together to offer flexibility and cost advantages, coupled with easy installation without the necessity of buying a new car stereo as in traditional solutions.”

This was posted by a Japanese DRM enthusiast. Anyone know more about it?

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.

20170902 #2: Check out this link to the ECDAV page on DRM. Google Translate says it is this: Digital AM (DRM)

China is a large-scale broadcasting power, radio station, a large number of users, the use of the latest digital technology, according to China's actual situation and the development of 30MHz amplitude modulation band below the digital sound broadcasting technology, China's traditional analog AM broadcast industry will have a huge impact, Promote China's sound broadcasting industry, technological progress, industrialization prospects are very broad, with significant social and economic benefits.

Digital Engineering Center Through several generations of academic leaders and their research team's joint efforts, the research direction in the digital sound broadcasting theory and system has laid a solid academic foundation, the research work in the leading domestic level, especially in the digital AM broadcast (ETSI ES 201 980), between China's Qiqihar and Beijing, Xinjiang Kashi and Europe between the two countries, the research and development of the theory, system and application development research in the international advanced level, developed by the short-wave amplitude modulation digital broadcasting system technical indicators fully in line with DRM standard Conducted a number of system experiments demonstration, testing and pilot are a complete success. Compared with the world's leading Thales system, its main technical indicators are consistent, can replace the EU similar products.

At present, our school is our country in the digital sound broadcasting major scientific and technological projects in the main commitment unit, mainly in the research project has the national 863 project, the State Administration of Radio, a major science and technology special projects and the Ministry of education key projects. Our research work has also been recognized by foreign counterparts, our center was invited to become a member of the DRM organization, and with the German and French well-known research institutions and experts to assume the EU's next generation of digital sound broadcasting research program - DRM PLUS.

Project 863 is further defined:

National 863 Project Subproject

Offshore engineering high-resolution to shallow detection technology - high-resolution signal acquisition and real-time processing system
High - resolution multi - channel shallow stratigraphic detection technology for offshore engineering Digital audio broadcasting application demonstration system.

and here:

...the "863" Project, the National Natural Science Foundation of China, the National Science and Technology Support Program Published a number of ministerial-level key projects of the SARFT. Has made a number of important basic research and applied research results, developed China's first short-wave digital radio transmitter, and solve the analog broadcast transmitter digital transformation of a series of key technical issues, identified to reach the leading domestic level; The first 30MHz following digital audio broadcasting national industry standards; in the country for the first time to build a short-wave video transmission system, applied in various departments of the country, has made important social benefits...

Here, a Japanese enthusiast reports the CUC-ECDAV on 15280-15285 kHz in DRM broadcasting CNR-1 audio earlier this year. I'm going to temporarily rest on the notion that China is broadcasting DRM for DPRK, until we can find out more. This could mean more DRM from China soon, as we have heard from other international broadcasters that are in-the-know!
