O HD não funciona na Europa? Na Suiça funciona

«With respect to digital radio, Europe is known as a 100 percent DAB Eureka-147 area, and the image of in-band, on-channel digital in Europe is very poor. Unproven arguments against IBOC are disseminated, like “technically not feasible in Europe because of many differences in the FM system,” and there is confusion of FM with AM HD Radio questions. Based on large DAB investments and a European digital FM system (DRM+) on its way to finalization, it is understandable no one is really interested in a “foreign” FM digital alternative. However, not even one European country has a commercially profitable DAB operation yet (with the eventual exception of the United Kingdom, where there is the chance to become profitable some years from now; CGap, the biggest U.K. operator predicts “digital break even” for 2010). Moreover, some thousands of local and regional (single-program) broadcasters are no longer so sure that a multiplex technology is the proper solution for them; perhaps more feasible and economically viable systems with a slow evolution path to digital should be found. That’s why the Swiss Federal Office of Communications (OFCOM) and the Association of Private Broadcasters (VSP) started to support our initiative to do some HD Radio field trials, and to follow any other kind of FM digital system that could be an alternative. The Swiss OFCOM granted the first European HD Radio test license at the end of 2005 for two years to Ruoss AG/Radio

. This license was extended until the end of 2008, and a total of three different frequencies are now allowed to be tested simultaneously.

Since field testing began, and especially after the successful HD Radio days in Lucerne in October 2006, HD Radio has begun to gather a lot of positive interest in Europe. The “false statements” about HD Radio have started to fade away, piece by piece. A good example of such false statements was that European FM deviation will have to be reduced below 50 kHz peak deviation, and the audio multiplex power to –6 dBr, to make it work. This argument has now completely disappeared. »
