Phoenix Radio, a FM pirate station which ran from 1979-1984 in London has launched a website. The station played indie/alternative music and built up quite a following in London. The website includes a history of the station, some audio recordings, a clip from a 1984 Channel 4 feature.
EDIT: Updated 4/8/25, the website seems to be offline but I have included the link to their Facebook page should they sort it out or launch a new website.
