frequency dependent dispersion in the ionosphere can affect sidebands

causing differential fading and distortion.

One could also consider selective fading.

that's just another name for it... i threw in the big words because
i'm sure that mr.b will look them up out of context and find all sorts
of hilarious ways to recombine them.

I am sure that the all my questions will be explained with the ionosphere.

Hardly.

At some frequencies the ionosphere is transparent, at some it is reflective,
at some it is absorptive.

And the iononsphere has little to nothing to do with ground wave propagation,
which predominates at AM broadcast frequencies.

But you haven't a clue what any of that means, do you?

The first my question was on the frequency doubling.
But yours selective fading means for me "distance itself does affect
sidebands". So you are very helpfull.

Correct conclusion but for totally wrong reasons, much like noticing ice
cream is cold therefor the sky is blue.

For me all names are clear.

Babble.

Ampere discovered the electrons and give them name "current elements".

You are wrong as usual.

Richard Laming came up with the concept, the name was by George Johnstone
Stoney, the particle itself was identified by Sir John Joseph Thomson.

Maxwell used "electric particless". But you all admire Heaviside's fluid
(massles and incompressible). Do you see the difference?

More mindless, word salad babble.
