I've tracked it down via Google this morning, it is Resonance FM, it seems to be in trouble, and there is a Real Audio stream at http://www.resonancefm.com/audio/resonance-realaudio.ram.
Nick Cohen, discovered it earlier:
To Resonance, London’s most endearingly eccentric radio station. From a cramped studio above a Soho Tandoori it broadcasts the weirdest playlist on the planet. If you are yearning for the best of Germany’s “electronic krautrock utopia” or “the different forms of Albanian music, art and culture,” then all that – and much, much more – is there for you at 104.4 FM or on-line on the Net. I was on its political programme and afterwards I asked if it was Resonance’s most popular talk show. “Oh no,” said the interviewer. “Our number one show investigates UFOs. I say ‘investigates’ but we do nothing of the sort. Last week the potty presenter put this killer question to his equally bonkers guest: “OK we agree that 11 forms of alien life are circling the world, but tell me: how many of them are reptilian?’”
