actually, it was radio caroline that started pirate radio in 1969from a vessel in the channel - hence the term pirate radio, radio luxemburge started shortly after. Kiss were the one of the first major london pirates to get a long term broadcast licence, but they did have the advantage of being on dry land and were able to use fm stereo in the 70's
I live in aldershot, about 30 miles from london where there can be 100+ pirate transmissions at the weekend. with the right kit i can pick most of them up.
The stations i mentioned are not "computer" or net stations - they actually broadcast over much of london and surrounding areas on FM frequencies by normal people who have a geniune interest in music. Music is the whole reason they do it
Mark, i'm not sure how far away you live from london, but for me to pick these people up on the radio, 30 miles requires the Galaxy 23 on this page- http://anas.worldonline.es/ronsmith/fm.htm
