![]() "david" napisał w wiadomości ... On Thu, 24 Mar 2011 10:53:09 +0100, Szczepan Bialek rearranged some electrons to say: " It was known that different frequencies travel with different speeds on a long cable". Is the same in air and space? S* No, how many people have to tell you that? And what they tell: "Because of the low signal-to-noise ratio, as with amateur-radio practice, EME signals can generally only be detected using narrow-band receiving systems. This means that the only aspect of the TV signal that could be detected is the field scan modulation (AM vision carrier). FM broadcast signals also feature wide frequency modulation, hence EME reception is generally not possible. There are no published records of VHF/UHF EME amateur radio contacts using FM." From: http://en.wikipedia.org/wiki/TV_and_FM_DX Could you explain it? S* |

You quote has absolutely nothing to do with the speed of propagation, you babbling moron. -- Jim Pennino Remove .spam.sux to reply. |
