Without the earth the static build up and radio stop working.

How would you know that when you don't even have a transmitter?

But my "friend" Marconi had a lot. He wrote:
"but in my opinion no practical system of wireless telegraphy
exists
where the instruments are not connected to earth."

You will transmit just fine if you have the ground/chassis/counterpoise.

And without it, fine as well.

It is not true. You know that.

Hello chaps.
Several of you have said that Szczepan seems unable to accept new ideas.

I see that he persists in believing Marconi's comment that an earth
connection is necessary. Those of us who use Yagi , loop or dipole aerials
know, through experience, that an earth connection is not necessary.
I am undecided why he prefers to believe the opinion of someone who worked
in the early days of radio rather than those of us who use radio in modern
times.

I feel it is awkward to say that Marconi was wrong even though we now know
this is the case. Personally, I'd say that Marconi's opinion that "no
practical system of wireless telegraphy exists where the instruments are not
connected to earth" obviously related to his own use of wireless. As I
understand it, Marconi's aerials were not resonant at the frequency he was
using. They would therefore be a mis-match to his radios and this situation
was alleviated by using connections to earth.

I find it puzzling that Szczepan feels happy to ignore our comments and
continue to accept Marconi's opinion given that he (Szczepan) said that a
transmitter is a "black box" to him. I've speculated that his English may
not be very good but I shall be amused if we find out that his first
language is English despite his non-English name.
He never answered my question about resonant / non-resonant aerials so I
guess his technical knowledge is limited.

Kindest regards to all,
Ian.

ps: If Szczepan is happy to constrain his knowledge to the days of Marconi
then I wonder how come he is using a computer. Didn't have those in the days
of Marconi.
