How cost-effective is a digital radio DRM radio set up compared with traditional terrestrial model? What is the minimum equipment needed and is there anyone who subsidises the enablement of digital technologies?

Three interesting questions in one so here are very brief answers to all. Digital transmissions are clearly more cost-effective as they can save energy of up to 90% in FM and between 40-80% in AM (as well as spectrum, while delivering more services in audio and text in better quality than FM). Digital is net superior to analogue and brings radio into the digital age. This can more than compensate for the extra equipment (to be acquired) needed to digitise a DRM transmission: a content server and a modulator (sometimes the latter is already included in modern transmitters). DRM is the only standard where existing analogue equipment broadcasting, if not too old, can be upgraded so that no completely new equipment is required. Radio digitisation is often a political, governmental, and commercial decision and the costs will always be borne by public or private companies and bodies. The DRM Consortium (www.drm.org) is a not-for-profit organisation promoting the standard and its clear and significant benefits for the listeners, manufacturers, and regulators.
