The Ardic DX Club, Chennai conducted an awareness programme among public and shortwave listeners in Chennai about Digital Radio Mondiale (DRM) on September 2, 2018.
The meeting started with T. Jaisakthivel, President of the Ardic DX Club welcoming members of the club and the public, who had gathered at Nageswara Park, Mylapore, venue of the meeting. He explained about the activities of the club and introduced the topic of the meeting—DRM.
N. Arun Kumar, one of the Ardic DX club member narrated his experience about buying "NewStar 111" DRM receiver from China in 2013. He explained in detail how DRM technology works and the advantages of the technology.
"A listener will be able to listen to his favourite DX station without any atmospheric noise or fading, in other words, one can listen to the programme in FM stereo quality, even a distant radio station which use to sound noisy in Shortwave can be heard with crystal clear audio, which is one of the biggest advantages of DRM," he said.
Listing out the other benefits of DRM he said that broadcasters would be able to send data such as text, pictures and Journaline to listener's DRM receiver.
Arun Kumar also said that All India Radio (AIR) has implemented DRM technology in most of its transmitters. "India is one of the countries which pioneered DRM when the technology was in its nascent stage. The Indian Government has invested several hundreds of crores for upgrading/replacing its transmitters to DRM," he said.
Dr. N. Mohan, one of the listeners who tunes into distant DRM radio stations using his Software Defined Radio (SDR) presented a demonstration of receiving DRM signal using his computer, which several of the onlookers watched with keen interest.
"I have been listening to several DRM stations using my SDR for longtime, I enjoy tuning to DRM stations and I have also been in touch with several radio stations broadcasting their programmes in DRM mode," he added.
On this occasion a book authored by N.Arun Kumar about radio titled "You are listening to" in Tamil was also released.
The meeting ended with members requesting the DRM Consortium to conduct an awareness programme in Chennai for the benefit of larger public.
