" I only knew 'Roger Tate' (real name Bob Tomalski) through listening to his programmes on the radio. He was a DJ on 'Radio Invicta', London’s first soul music radio station, launched in 1970. Invicta was a pirate radio station. Back then, there were no legal radio stations in the UK other than the BBC.

The notion of a campaign for a soul music radio station for London had been a little premature, given that no kind of commercial radio had yet existed in Britain. But that is exactly what Radio Invicta did. As Roger Tate explained on-air in 1974:

“Who are Radio Invicta? You may well be asking. Well, we’re an all-soul music radio station. We’re more of a campaign than a radio station, I suppose. We believe in featuring more good soul music on the radio.”
