Juan San Ildefonso, director and presenter of the programme "Amigos de la Onda Corta", on Radio Exterior de Espa?a, speaks to the journalist, consultant and trainer Gorka Zumeta. "Radio has to decide what it wants to be when it grows up", says Zumeta in reference to the two paths that are currently being considered to guarantee the future sustainability of the medium: the traditional broadcast channel, broadcasting via radio waves, and the digital content distribution channel represented by the Internet. "RNE is leading a process of implementation of DAB+, although it recognises the delay that has been incurred, but its current commitment is absolutely determined, just as it also led, in the 1960s, the arrival of FM in our country," recalls Zumeta.
