Cadena SER Bilbao broadcasts debates, sports coverage and news to the Basque Country from a station whose lineage stretches back to a Bilbao broadcaster that predates the Spanish Civil War. It carries the SER name, the acronym for Sociedad Española de Radiodifusión, a network built on top of one of the oldest continuously operating radio brands in Europe.
A Network Born in 1924, Reshaped by War
SER's origins trace to Radio Barcelona, which went on air on November 14, 1924, under the call sign EAJ-1, and to the founding of Unión Radio in Madrid weeks later on December 19, 1924, under the direction of Ricardo Urgoiti. Unión Radio grew into Spain's dominant commercial network by chaining regional stations together starting in 1927, but the Civil War interrupted everything: its Madrid station was seized in July 1936, broadcast Republican propaganda including Dolores Ibárruri's "No pasarán" speech, and was finally captured by Franco's forces in March 1939. Out of that upheaval, the network was reorganized as SER on September 25, 1940.
Bilbao's Own Station Predates the SER Merger
Bilbao's local station has its own separate origin story. Radio Emisora Bilbaína, broadcasting under the call sign EAJ-28, went on air on October 31, 1933, in a city that had come relatively late to radio compared to Madrid and Barcelona. After the Civil War it was renamed Radio Bilbao, and the station joined the SER broadcasting network in December 1943, folding a decade of independent Basque broadcasting into what was becoming Spain's largest radio group.
Debates and Deportes in a Football City
Cadena SER Bilbao's current format, built around debate programming and sports coverage, lands in a city where sports talk carries real weight. Bilbao is home to Athletic Club, one of Spanish football's most historically significant clubs and the only La Liga side that has never fielded a player who wasn't developed through Basque academies, a policy that makes matchday commentary here less about transfer gossip and more about regional identity. A station built on debates and deportes fits naturally into a city where the local team's philosophy is itself a constant subject of conversation.
A Century of the Same Network, Still Local
What makes Cadena SER Bilbao worth tuning into isn't novelty, it is continuity. The parent network has now run for a century under one name or another, weathering a civil war and a dictatorship along the way, while the Bilbao station itself has carried Basque news and sport on the same frequency lineage since before Spain's democratic era even existed. Few stations anywhere can claim that kind of unbroken institutional memory, let alone one still delivering live debate and match commentary every day.
