Many years ago, when I was staying in Letchworth, Herts. whilst on my Electronics training course, during an atmospheric 'lift', French TV sound broke in over BBC1, whilst the pictures were disturbed by interference from the French transmissions. This of course was back in the analogue days, when BBC & ITV were using 405 lines on VHF Channels, and French TV used 819 lines.
