I don't really get what you're after. What form should the example be in?
The example should show that people are doing this alone, and see signals from the Moon at the required delay. You have provided material for children.
The instructions are so simple, if you are a licensed HAM radio operator with the equipment listed, that even a student could do it. Are school-aged kids incapable of performing experiments? Yours is a very odd argument, if you could even call it that.
Yes, it's a European Science Teachers site. So what? And yes, it says, "If the radio amateur sends the signals from the amateur radio station, the returning signals can be streamed via the internet to be viewed at your school." So what? The actual bounce and measurement doesn't NEED the internet. (Remember, HAM's have been doing this for decades, long before the "Internet"). All they are saying is that the HAM operator can send the results to your school. If you read the instrux again, a single operator can perform this, no streaming, no delays. Just log your oscilloscope results and do a little math. Done.
The internet has existed for "decades". You have no further material to provide and must insist on this material written for children that you found.
Yes, the internet has been around for decades. And HAM Earth-Moon-Earth transmissions are decades older than the internet. In fact, from an article published by The National Association of HAM Radio (ARRL):
"
A team of folks at the Signal Corps Engineering Laboratories accomplished the first attempt at bouncing signals off the Moon on January 10, 1946 on a frequency of 111.5 MHz...The return echoes from the Moon were both visually and audibly recorded.
The first amateur work at receiving one’s own echoes was accomplished back in 1953 on 144 MHz by W4AO and W3GKP... It was not until after many years of work that the first 2304 MHz EME QSO took place between W4HHK and W3GKP on October 19, 1970."
https://www.arrl.org/files/file/Technology/tis/info/pdf/0210028.pdfRegarding W4HHK and W3GKP moon bounce transmission (and others), here is what their transmission looked like:
From the same article, here's what W5LUA had to say about his first attempt at an EME, "
On a cold winter night in December, I was poised and ready to “bleep” at the Moon. My four 14 element Swan antennas, 500 W at the antenna and my 1.5 dB highly optimized homebrew LNA were ready. At the sight of the Moon coming across the horizon in Richardson, I sent out three dashes and upon returning to receive, I heard dah-dah-dah! I could not believe it. I did it again and again. Every time I heard my echoes. Boy, was I in heaven! "
And, btw, he was a solo operator. In other words, he transmitted and received his own signal. I don't know why you're hung up on this 'you need the internet' thing, because you don't. And this 'you can't do it alone' thing, because you can. And this 'kids can't do it' thing, because it's pretty straight forward with the right gear and license a kid could do it.
