AIR has acquired 37 DRM transmitters, in talks to get cheaper radio sets

NEW DELHI: All India Radio (AIR) has introduced digital radio technology in the AIR Network by installing new state of the art Digital Radio Mondiale (DRM) Technology transmitters by replacing old outlived 37 Medium Wave/ Short Wave transmitters.

Minister of State for Information and Broadcasting Rajyavardhan Rathore told Parliament however that the provisions contained in Policy Guidelines on expansion of FM Radio broadcasting services through private agencies (Phase-III) do not provide for private FM broadcasters to adopt digital radio technology.

He said Digital Radio allows significant improvements in service reliability, audio quality, more radio services and higher efficiency.

The new AIR transmitters include 35 new state of art technology Medium Wave (MW)/ DRM transmitters as a replacement of old technology valve based MW transmitters. Additionally, two new state of the art technology Short Wave (SW) DRM transmitters have been approved for installation as a replacement of old SW transmitters.[…]

PantronX Titus II update

Many thanks to Mike at PantronX who has provided the following update on the Titus II portable SDR:

As you can imagine the response to Titus has almost been overwhelming! Pre-orders far exceeded our imagination and excitement from broadcasters has been very loud. DRM and digital broadcasting seems to be reinvigorated with Titus in 2017. I think we really broke the price barrier that most everyone has been dreaming of and provided the flexibility
that has held back the cause.

As posted on http://hfcc.org/delivery/receivers.phtml

‘Update on availability received from PantronX: “We have been overwhelmed with the response to Titus with orders and request – coupled with an early Chinese New Year that the pre-production date has slipped a bit. Please be patient as we work with our suppliers and add more functions.” ‘

We are doing all we can to push – Chinese New Year is a crazy time – the factories are shut down for 3 to 4 weeks and as you can imagine the stress prior to and the performance after.

Hopefully in the next couple of weeks our http://titusradio.com/ website will undergo a much needed update. So much to do – but we are making good headway.

Thank you, Mike! I’ve had a number of readers asking about progress on the Titus II, so I appreciate the update!
