We had some people around last night and one of them started dripping on about Electro Magnetic Pulse. He was saying that anything with a transistorised circuit of any sort, no TV, no radio, my MP3/MP4 with all my "art" collection etc. I didn't know enough to argue and, quite frankly, wasn't that interested at the time. When I got to thinking about it, was he right? I always understood that micro electronics would be permanently damaged but how would radio communication be maintained if only to get the Government announcement of "Good luck everyone"
