In November 1965, RNE launched a second network that used FM transmitters and specialised in music. The channel was branded Radio Clasica and inaugurated at Noblejas in Toledo. The Noblejas transmitter was built especially for the external services of the RNE. Later, the Arganda del Rey transmitter was built, but was less powerful. In 1975, the external services underwent a radical reform and all RNE channels were rebranded to only broadcast Spanish language programs.
