I don't remember any particular incident, but I wouldn't regard it as particularly unusual. When there's unusually high atmospheric pressure over Western Europe it's not unusual for domestic radio and TV signals to suddenly disappear under signals received from France, Germany and further afield.
Also, solar flares on the sun's surface can sometimes lead to what radio enthusiasts call a 'lift'. When this happens, there can be very brief periods when radio signals carry much, much further than usual. (e.g. a taxi company in London could suddenly hear transmissions from, say, another company using the same frequency in Canada).
If a solar flare occurs during a period of abnormally high pressure, radio and TV signals across a vast area could "go crazy" for a short while, with 'mysterious voices' and noises being heard from TV and radio sets. (You might, for example, be watching BBC1 in Leeds and suddenly hear a guy on a building site in Latvia using his walkie-talkie. Such effects usually only last for only a few seconds or, at most, for a few minutes, but they're not particularly rare).
