    If have a decent "long wire", you can in the right conditions pick up stations anywhere on the planet but you are more likely to pick up taxi just outside your window

    The reason you pick it up in the first place, is that cheap power supplies and cheap audio circuits often do not have any filtering and a set of powered speakers can just act as a radio receiver. e.g Mobile Phone noises when your phone is trying to connect to a Cell Tower.

    For more info check out. Harmonics, "Skip" and the Ionosphere.
    Mobile (or Cell Phone) interferance with audio equipment has always been an issue regardless of quality (though higher quality items seem to reduce the effect somewhat).

    I am surprised that if it is a quality issue, to pick up LW, MW and SW stuff from around the world on something made by Logitec which I thought was a decent company is a surprise.

    Though I do think the radio stuff is helped by living in a part of the UK nearest to France.

    Thanks for the responces guys, is clear now why I got this issue, I find the signals quite interesting actually.

    I wonder if they still have those exceptions for certain stations...
