More great DRM news from Asia

Several fine bits of news...

WINB reports via Twitter: "CNR 6030 DRM service is now 24 hours." 

and Brother Alokesh reports:
"All India Radio, Bangalore has re-commissioned its 500 KW DRM SW transmitter with effect from 3rd August, 2018. DRM transmissions were off air since 27th Feb 2017 as the main tube failed.

Tentative schedule in DRM mode :

DRM car radio in India

Watch this videoI want one!

I hear a little drop-out, but the audio is nice and the display is clean and simple for a dashboard. I have no details about the unit or specs yet, but will post some when I have them.

Looks like Ruxandra (DRM Consortium Chair) is the passenger. From what I can tell, this was taken recently at BES (early February 2016) in New Delhi.

Here is to hoping India's roll-out has the ability to break-free the hardware situation for DRM.

UPDATE: 20160223 - DRMNA reader Oliver in Brittany, France writes:

"If it may help, the car with the integrated DRM receiver is the new TUV300 from MAHINDRA
launched september-october 2015 (with AM/FM only for the moment).

Sorry, don't know which is the unit manufacturer (Panasonic ? as they work close with NXP on the SAF360x chip).

Best regards from Brittany (France) where a new AM radio (Bretagne 5 on 1593 khz, which means Brittany 5) tries to convince the french regulator to authorize them to transmit in DRM mode, and to ad the DRM norm along the DAB+...

Merci Oliver! We greatly appreciate the details.
