Cadena SER Radio San Sebastián

One word in the name is ordinary Spanish rather than branding: Cadena is network. Worth a line for anyone reading a list of stations in a language they do not have.

This is one of the quieter entries in Spain's listing, at 417 of 487. Stations at this depth are usually community, religious or single genre broadcasters rather than national networks, and the country's numbered pages are the only route to them.

The directory records no opens at all for Cadena SER Radio San Sebastián. That is a fact about the directory rather than about the station: a stream nobody has opened through radio-browser can be perfectly healthy and well listened to on its own site or on a radio. It does mean this page is where the station's directory history starts.

The audio comes from playerservices.streamtheworld.com, and 57 other stations in Spain are served from the same address. That is a streaming platform carrying many broadcasters rather than a station running its own server, which is worth knowing for a practical reason: when a platform has a bad night, a whole block of Spain's listing stops answering at once and nothing is wrong with any of the stations in it.
