electrons to say:


" It was known that different frequencies travel with different speeds
on a long cable".

Is the same in air and space?

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:

Could you explain it?
