Not all know that:
""The necessity or utility of the earth connection has been sometimes
questioned, but in my opinion no practical system of wireless telegraphy
exists
where the instruments are not connected to earth."

And those who do are WRONG!!

The trouble is that you keep taking old outdated quotes, out of context,
and do not understand that theories and knowledge have moved on.

Is even one textbooks where is wrote that Marconi was WRONG?

Yes, every modern textbook on electromagnetic theory.

See Electromagnetics by Kraus and Carver, Chapter 14, Antennas and Radiation
as but one example.

Are your transmitters without any earth?

Yes, some of them are, some of them aren't.

I am checking from time to time if your knowledge have moved on.

You are just babbling because you can not accept the fact that a lot was
learned after Marconi died, some of which is in direct contridiction to
some of the things he thought were true at the time.

It is still true?

It was NEVER true; Marconi was wrong.

Here's a news flash for you:

A lot has been learned about radio since Marconi.

The radios on Pioneer 10 worked just fine 12,000,000,000 km from the Earth.

Such a question would only be asked by someone who is unaware of radio
communications by handhelds or by radios in vehicles, aircraft or
spacecraft. In other words, no sentient person should ask it.

I'm plonking this troll, this goon, this rimless zero.

Of course, you can play with him if you wish ... but serious discourse? Ha!
