I think the effect that you describe is due to 'tropospheric ducting' which typically occurs over large bodies of water. I guess it is the same effect that allows you to pick up FM radio signals from across the sea when there are just the right atmospheric conditions. |
yeah, my sentence was a bit messed up. Of course Malta is always 1000km away - but you can not always pick the signals. Only if there is a duct as you already described.
