All India Radio tender notice for DRM digital transmitters.
India's public service broadcaster All India Radio (AIR) is putting into practice its plans for digitalisation of radio and has placed a global tender notice for the procurement of several DRM digital transmitters. AIR has invited bids for the supply of 34 new MW transmitters, for the upgrade of 36 MW transmitters and purchase of 5 SW transmitters and other associated equipment. The Research Department of AIR is also going ahead with the purchase of a 500 watt DRM shortwave transmitter for conducting trials on 26 MHz SW DRM transmissions for local coverage. The details of the tender advertisement can be found on the official AIR website:
http://www.allindiaradio.org/NIT/Tenderenquiry-13/18006010.html
This procurement process is the start of the AIR's digitalisation plan of ensuring DRM Digital radio coverage for the entire country, thereby providing better and more robust radio services to the listeners.
Earlier this year, AIR had placed orders for the purchase of two 1000 KW DRM capable transmitters which are now being made ready for inspection and delivery. These MW transmitters can be operated in DRM mode, in analogue or in simulcast mode and provide coverage to very large areas in the Indian subcontinent. The transmitters have been manufactured by Thomson Broadcast & Multimedia, A.G.
And recently All India Radio has also confirmed the purchase of 6 mobile DRM transmitters of 10 KW each which are AM/DRM ready. These containerized transmitters are meant to be used in disaster management CASES as they can be easily transported to the affected areas by air/rail/road. A 60 meter medium wave mobile mast goes in another container which can be easily erected together with the transmitter and start broadcasting as and when required. These transmitters are being supplied by M/S Riz, Croatia.

DRM broadcasters' user guide released
The DRM Consortium has produced a new up-to-date Broadcasters' User Guide
intended to provide a source of relevant and authoritative information on
the full DRM Digital Radio broadcasting system.
It is aimed at broadcasters considering the transition from analogue to
digital broadcast in the AM and VHF broadcasting bands using what many
believe to be the most advanced and flexible digital radio broadcast system
today. It will also be of interest to manufacturers, service-planners,
administrations and regulatory bodies involved with broadcasting systems and
policy.
The document is intended to explain how and why a broadcaster might go
digital, from both technical and commercial perspectives, describe the basic
operation of the DRM system (DRM30 and DRM+), provide a definitive source of
references to key technical standards, including regulatory, co-ordination
and planning information for DRM broadcasting.
The Broadcasters' User Guide also provides detailed information on other
useful features, such as bespoke commercial applications designed to run on
the DRM platform. The Guide has eleven chapters with illustrations and clear
explanations on themes such as the DRM technology and content, the network
infrastructure, receivers, IPR and references to DRM system related papers
and published articles.
"The Broadcasters' User Guide is a reference document for anyone interested
in understanding and implementing this complete global, digital radio
standard. It addresses the specialists and enthusiasts in equal measure and
as such it is the free contribution that the DRM Consortium would like to
make to the broadcast industry and the revitalisation of audio broadcasting
in the digital age", said Ruxandra Obreja, DRM Consortium chair.
The Broadcasters' User Guide is available in booklet format from the DRM
Project Office and also on the DRM website where it can be downloaded in
PDF format.

INDIA
AIR to get 2 MW DRM transmitters for Gujarat, W Bengal
All India Radio (AIR) has placed an order for the supply of two 1000 kilowatt DRM capable medium wave transmitters. These will replace old analogue transmitters of same capacity at Chinsurah (West Bengal) and Rajkot (Gujarat), with state-of-the-art solid state transmitters.
The new Megawatt transmitters can be operated in analogue, in simulcast or in DRM mode with automatic change-over between these three operational modes. The transmitters shall provide coverage to very large areas in the Indian sub-continent as well to the West, North, East and Southeast Asia.
This significant purchase was revealed at the recently concluded Broadcast Engineering Society (BES) India’s conference in New Delhi, attended by exhibitors and participants from all over the world. The need for cheaper digital radio sets and content innovation was highlighted by speakers during the event.
All India Radio has already chosen DRM as the technology for converting its vast analogue network to digital. This is part of its digital radio switchover strategy where more than 40 transmitters are to be made DRM capable in the near future. AIR is already broadcasting in DRM from one of its high-power shortwave transmitter located at Khampur near Delhi that covers an area of approximately 800 kilometre radius.
The DRM Consortium says the development underlines the commitment made by India to new technology in general and the DRM standard in particular.

SPAIN
Things seems no to be very clear at RNE about the Arganda-1359 operation.
After starting the 24h. DRM operation recently, the whole past week they were
broadcasting in noise mode only from 1900z to @0700. During daytime the frequency was empty. This morning (Nov. 23rd 2009) they switched off the DRM tx. at 0657z and in some moment along the day they started in AM again. Now, at 2034z I can hear the Arganda tx. in AM. The past week the DRM operation did not contain the scrolling text announcing 24h. operation but only "RNE DRM ARGANDA-1359 Khz".

SPAIN
After several years the medium wave DRM broadcast of RNE (Arganda 1359) has passed its testing phase and has become a regular one on the air 24 hours a day. The ID is "E7C238" and the program is labeled as "RNE DRM Arganda". I think the power isthe same: 10kw.

Spain via mwcircle yg (3/11-2009)
I wonder how large its audience is? Are there any DRM receivers for sale in
Spain?
73 Steve Whitt via mwcircle yg (3/11-2009)
Well, as in many other places... no receivers=nobody listening to. It is a toy for engineers. And I suspect that few people will be fooled by "DRM, The Intermitent Radio" to buy a new and expensive receiver. Let´s see!
Mauricio Molano via mwcircle yg (3/11-2009)
Does this also mean there are no more analogue transmissions from Arganda Del Rey on 1359 kHz?

DRM
RECEIVER PROFILES
released at IBC 2009.
The DRM Digital Radio Receiver Profiles, which define minimum functionality for different classes of digital radio receivers, have been released in Amsterdam at IBC today. The Profiles aim to help manufacturers build stand-alone DRM or multi-standard receivers and stimulate digital radio markets across the world.
The Receiver Profiles offer significant benefits to all stakeholders in the radio market; for broadcasters they provide assurance that their services will be receivable and for manufacturers that their technology investments will be supported by a wide choice of services. For consumers the Receiver Profiles ensure that the products they purchase have the necessary features to offer consistent quality and assured levels of interoperability
across their region and beyond. Regulators can use the Receiver Profiles to develop strategies and policies for digital radio broadcasting within national boundaries or with reference to trans-national and harmonised markets.
The Profiles have been developed by the DRM Consortium with the aid of its member experts representing silicon chip manufacturers, consumer device manufacturers, radio broadcasters and other experts from across the industry. The development of the Receiver Profiles has taken into account important market considerations
including the consumer experience, manufacturing issues and broadcaster requirements.
Lindsay Cornell, Chairman, DRM Technical Committee and BBC’s Principal Systems Architect, says: “Products conforming to the DRM Receiver Profiles will provide a step change in usability over analogue radios. The Profiles are composed of mandatory features which must be implemented and recommended features which offer enhancements with wide appeal. Manufacturers may offer additional features in order to differentiate their product from others.”
Ruxandra Obreja, Chairperson DRM and Controller Business Development, BBC World Service, says: “The DRM Consortium will actively encourage its members to adopt the DRM Digital Radio Receiver Profiles. With ETSI approval of our system enhancement to include DRM+, DRM offers a total solution for digital switch over. The Receiver Profiles should stimulate the receiver manufacturing industry paving the way for full DRM roll-out”
