In January 2004, a message arrived from 'J', who was in the process of constructing a new website featuring important locations in the history of The Who. J said:

"Radio London was obviously fairly important in that it featured heavily on the band's 'Sell Out' album from 1967. Now, here's my (probably utterly stupid) question! Would you please possibly be able to tell me roughly whereabouts Radio London was located offshore? I don't need exact co-ordinates (though that'd be nice!) just something so I can stick an 'X' on a map. Thanks for your time, and thanks in advance!"

J's question prompted us to realise that this vital piece of information was missing from the Radio London site, so we sprang into action to rectify the matter.

The Galaxy was anchored 3.5 miles off Frinton-on-Sea, Essex and her exact position was broadcast daily. In 1965, the Managing Director of Radlon Sales, Phillip Birch, was so impressed with a suggestion received from a listener that the ship's position of should be broadcast as a navigation aid to aircraft and shipping, that he sent a memo instructing staff to do this every morning at 08.00.

A recorded announcement of the Galaxy's position as "fifty-one degrees, forty-seven point nine minutes north; zero-one degree, twenty point five-five minutes east" was then broadcast daily from April 1965.

The map is based on one included in Brian Long's privately-published book, The London Sound, with many thanks. Clint has a map showing stations located throughout Europe on his excellent 'Sixties City' site. J's website about significant Who locations seems to have disappeared, but Googlemap has one showing locations in the city of London.
