came out almost dead on 300m/microsecond. Used .wav file recording of
transmit and echo and a good sound file editor with sub-millisecond
resolution when zoomed.

I have checked the Moon history and now I know that on Oct. 28 2007 was
"full Moon" at perygeum. So the speed was close to 300m/microsecond.


Well that's a nice bit of trivia you bring up, but that was not the
correct date, and not even the correct decade.

So why did you bring it up?

On Oct. 28 2007 radio echo appeared after 2.4s.

But I am steel loking for the evidences that the speed of radio waves is
temperature and wave lenght dependant.

You won't see it except when it's not in vacuum and then it's very
difficult for people like you to detect it. You actually have to do
something.

Are many people who detect physical phenomenon. I am looking for the
description.
