DRM+ to be tested in Germany

November 24th, 2007 | by Andrew Ó Baoill |

Enda O’Kane pointed me towards an announcement of the first field trials of DRM+ on the FM band. DRM (Digital Radio Mondiale) is being touted in Europe as a digital radio system that would replace current FM broadcasting, being preferred to DAB by many observers. It’s described as “the universal, openly standardised, digital radio system for short-wave, medium-wave and long-wave – digital radio for the radio frequencies below 30MHz” and DRM+ is the extension to bands up to 120MHz. Interestingly, it’s described as “near-FM quality” which raises questions as to why one would wish to move from FM to DRM+. Not fading and allowing limited text – something we already have with RDS – seem limited benefits. The main benefit would seem to be the relatively narrow bandwidth of channels – from 4.5 to 20kHz, with 9 or 10kHz being most common.
