Russia to test DRM over FM

(Source: Radio World via Michael Bird)

Russia will begin testing the Digital Radio Mondiale digital radio standard in the FM Band in July in St. Petersburg.

Russian firms Digiton and Triada TV are working with Fraunhofer IIS, RFmondial, chipmaker NXP and others to carry out the pilot.

The organizers will install a DRM-capable transmitter mid-July and begin regular simulcast broadcasts (DRM for FM) immediately after site acceptance checks are complete. The transmitter will reportedly be on air for six months and have an analog transmitting power of 5 kW and a digital output power of 800 W.[…]

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

Hi Thomas,

This month’s DRM Newsletter from the Digital Radio Mondiale Consortium has announced that a chip has been developed and introduced to make DRM receiver manufacturing easier and cheaper. It’s to be made available soon in a module with a header connector for developers, radio manufacturers and radio experimenters. This might be the tipping point for the development of high-quality, low-cost multiband DRM-capable receivers!

(Source: DRM newsletter)

At the MBT conference, the Consortium representatives had a chance to update participants with the latest DRM developments across the world showing DRM in action and new receiver solutions.

On May 23, at the meeting, a new DRM module (W102) with integrated hard coded baseband decoder was launched by Starwaves. The module will be suitable for applications such as consumer radios or aftermarket automotive solutions. The module contains a high-quality tuner frontend and audio DAC as well as a digital input for external audio sources e.g. from an external MCU to provide Bluetooth or USB audio. It measures only 40x40mm and covers all bands from LW, MW, SW to the FM Band (64-108 MHz) in DRM and analogue radio. All data services such as Journaline or MOT Slide Shows can be extracted from the data stream for further processing in the target device. The module will be available for order in the 3rd quarter of 2019.

Inntot Technologies focuses on SDR based DRM+ Receivers

[…]Inntot Technologies provides software-enabled IP solutions for Digital Radio Mondiale (DRM for AM and FM band, a set of digital audio broadcasting guidelines) enabled receivers, DAB/DAB+ (digital audio broadcasting) enabled receivers and ISDB-T (A technical standard for digital TV broadcast) Digital Television paving way to digital radio transmission.

Though the transmission side in India is almost ready, next-generation digital radio receivers are expensive (can go upto INR 14K), which is posing as a hurdle in the common man from benefiting from the features offered by digital radio.

[…]Inntot Technologies is facilitating software-defined radio (SDR) based DRM+ Receiver solution, wherein the software can be embedded directly to the fixed receivers, automotive/in-car radios, smartphones, as well as USB dongles.

[…]Inntot solution is different from using a separate hardware demodulator which adds to the overall cost of the digital radio receiver.

Inntot’s software solution can also help OEMs, radio receiver manufacturers, and semiconductor chip manufacturers in:

  • Doing away with the recurring cost of the demodulator chip, which, in turn, will reduce the bills of material (BoM) cost — ideal for a high-volume market like India
  • Easy portability on platforms like Android
  • Reusable, fully standard, and specifications-compliant complete stack and no external dependency on any vendor
  • System integration and field testing

[…]Inntot is not the only company looking to offer cost-effective DRM receivers. Launched in 1993, the New Delhi-based OEM manufacturer Communications System Inc., has also put up its digital radio for sale on online websites like Amazon, and IndiaMart.

As of May 2018, the company has put up a notice for being in production for the second batch of digital radio receivers. However, despite tracking for weeks, its status remains ‘currently unavailable’ on Amazon, while we were not able to place an order from Indiamart.[…]

Encompass (BBC content) Encompass DRM tests from Woofferton are planned for March 26th and 27th:

  • 1200-1300 UTC 11780 kHz
  • 1500-1600 UTC 11790 kHz”

Very strong signal on 11780 kHz now.

Thanks for the tip, Mauno!
