Line 81:

Ireland's public service broadcaster and owner of the sole national transmission network, [[RTÉ]], launched its DAB service to the East and North-East on [[November 30]], [[2006]], using Channel 12C.<ref>[http://www.rte.ie/radio/dab.html RTÉ.ie Radio: Information<!-- Bot generated title -->]</ref> It initially began with six stations (four live), consisting initially of the RTÉ radio stations. Currently, it carries the four RTÉ stations, an occasional simulcast of the [[Mediumwave]] version of [[RTÉ Radio 1]], and four new RTÉ digital-only services, as well as some trial services.

Nearly a year previously, on [[December 20]], [[2005]], RTÉ announced that DAB trials would begin along the east coast on [[January 1]], [[2006]]. This date was 80 years after Radio Éireann (RTÉ's predecessor) began. By [[January 5]], two transmitters, [[Clermont Carn]] and [[Three Rock Mountain]], were transmitting a single multiplex on channel 12C, carrying 6 channels - [[RTÉ Radio 1]], [[RTÉ 2fm]], [[RTÉ Lyric FM]], [[Raidió na Gaeltachta]], [[Today FM]] and the [[World Radio Network]], all at 192 [[kbps]]kbit/s. In May, this was reduced to just RTÉ Radio 1 and RTÉ 2FM at 160 [[kbps]]kbit/s. These test DAB transmissions ceased on [[July 13]] and DAB remained off-air until the public commencement that November.

A second multiplex appeared in Dublin (Three Rock Mountain transmitter) on block 12A in March 2007 carrying [[Today FM]], [[Q102]], [[Phantom 105.2]], [[FM104]] and [[98FM]]. Today FM was removed from the RTÉ mux on 12C at this time.

=== Spain ===

Spain has a DAB population coverage of 60%.

There are three national multiplexes: public (192 [[kbps]]kbit/s each, but the public classical music radio station has 224 [[kbps]]kbit/s stereo, REE has 160 [[kbps]]kbit/s mono), and commercial (160 [[kbps]]kbit/s stereo) radio stations, with 6 services each. Two radio stations are DAB exclusive but have poor programming (music jukebox).

==== Catalonia ====

Catalunya Ràdio the Catalan public broadcasting station broadcasts four simulcast radio stations in DAB with a bitrate of 192 [[kbps]]kbit/s. It broadcasts two exclusive radio stations in DAB: Catalunya Digital 1 and 2 with 192 [[kbps]]kbit/s each. Catalunya Digital 1 offers music in Catalan and Catalunya Digital 2 offers varied music with the inclusion of the name of the artist and the title of the song that is being listened to.

The public Catalan broadcaster has 85% of population coverage but it has three broken DAB transmitters (Rocacorba, Alpicat and la Mussara) that reduce the coverage.
