Szczepan - do you hold an amateur radio licence, please?

I have even never seen a transmitter.
For me it is a "black box".

I only want to know if the box is connected to the earth/chassis.

Your the first answer was Yes ("The "static to earth" in my HF aerial is
merely to get the static to bypass my receiver).

Hello Szczepan.
It seems that you totally misunderstood my answer.
A ground connection is NOT necessary in order to receive a signal.

You tell me that you have not seen a transmitter and regard it as a black
box. I recommend that you get a modern textbook on radio technology so that
you can understand how radios and aerials work.

Kindest regards, Ian.
