He underlined the energy-efficient broadcasts on several channels while using one frequency, and the valuable emergency warning functionality (EWF), vital during disasters. He also made references to the broadcast of information using the advanced text feature application called Journaline, as well as to multimedia possibilities on the radio’s screen (like slide shows). Dr. Mohan also demonstrated the quality of DRM broadcasts by AIR Chennai (711 KHz and 783 KHz) and by the BBC (15620 KHz) using an SDR based device.

Dr., Mohan’s presentation was well-received by the students. They showed their support for the DRM standard as demonstrated by the feedback given at the end of the event.

Dr.T. Jaisakthivel, the organiser of the seminar, emphasized also that the students need to take and make available the various forms of digital communication to the rural population using the written and radio media platforms.[/vc_column_text][/vc_column][/vc_row]
