please keep mr. B on topic!

This babbling moron has been posting his nonsense for years on the physics
and physics.electromagnetic groups.

When I first read his posts years ago I thought his gibberish was because
English wasn't his native language but soon came to realize that the issue
isn't language, the issue is brain chemistry.

Recently he has moved to the amateur groups, I guess in hopes that the
people here won't be as "harsh" as they are in the science groups.

You can give him facts and links all day long, but since he doesn't seem
to have more than two synapses that fire properly, he will never
understand
any response and just continue to babble on.

So there are a few choices to answering his posts:

Don't

Remind him he is a drooling mental case

Respond with some facts that may be of interest to others when he
accidently
hits on something, such as the history of broadcasting, then remind him he
is a drooling mental case.

Do not be angry that you do not know if " did distance affect the
sidebands???? ". It is nothing wrong.
The effect is obvious in light of physics laws. Such obvious that fathers of
the radio did not write about this.
Young people can measure it if it is interesting for them.
S*

distance itself does not affect sidebands.

frequency dependent dispersion in the ionosphere can affect sidebands
and the mark/space tones of rtty differently over short periods
causing differential fading and distortion.
