"There's not a lot written about 2BP," says our guest Tony Currie, radio historian, author and presenter. And yet for episode 48, we've wrung a whole 40mins out of it!

In January 1923, the BBC had sole right to broadcast in Britain, and yet a couple of experimental radio stations existed in Glasgow. 5MG had been on the air since October, operated by shop-owners Frank Milligan and George Garscadden, just to sell some wireless sets. And Daimler wanted to sell something too - in-car radios. So they set up a temporary station, 2BP, at the Glasgow Motor Show.

Pull over and hear all about it. Plus from Scotland to Somerset: hear Neil Wilson's tour of his wonderful Radio Museum in Watchet.
