No, you babbling moron.

A Tesla coil specifically refers to a resonant transformer
specifically
designed to produce high voltages, typically much higher than 10,000
volts.

The coils in radio transmitters and receivers are part of resonant
circuits
specifically designed to provide either bandwidth limiting or
impedance
matching or sometimes both.

Who was the inventor of this "coils in radio transmitters"?
S*

The first person to NOTICE that resonance exists in a capacitor and
inductor
circuit, thus forming a tuned circuit, was Felix Savary in 1826.

The first patent for a spark-gap transmitter and a receiver with tuned
circuits in them was filed by Oliver Lodge in 1897.

But the transmitter was very weak. To be efficient it must has "the
resonant
transformer specifically designed to produce high voltages".
Who was the inventor of the "the resonant transformer specifically
designed

When you are so obsessed with history, why don't you do your own research?

Asking questions here will never be useful for you because you are not
the type of man to accept any answer.

I am not "obsessed with history".

"My question was:
"Now is 2012. Is " this curious apparatus" the "fundamental part of modern
radio"? Of course in form of the " variations of Tesla coils and Tesla
coil circuits".

In 1924 Marx invented the High Voltage Generator without coils.
Tesla Coil is also HVG.

So I modify may question: "Are in today transmitters the "variations of
Tesla
coils" or the "variations of Marx generators".
Or "is possible to do the transmitter without coils"?
If Yes, when was the first?

I have never seen a transmitter (even that in a mobile phone).

Neither, some of Tesla's equipment may have made use resonance, but they
are not the root of resonant circuits used in modern equipment.
ie Tesla coils did not turn into the circuits used today.

Yes.

Microwave transmitters routinely use resonant devices other than coils and
capacitors.

Yes. It was impossible to "make" the microwave frequency using coils.
Magnetrons are for it.

But are the modern radio waves (ham) transmitters without any coils?

No, it is not "impossible", just more difficult the higher in frequency
you go.

At lower microwave frequencies it is a coin toss whether to use coils
and capacitors or other things.

Magnetrons are for it.

Magnetrons are not relevevant to the question.

But are the modern radio waves (ham) transmitters without any coils?

It is possible, at least at low HF, but not practical in general.

You are babbling.

Generally they have coils, but NOT Tesla coils, it would be possible to
not use coils, but it not usual. (Depending on what you call a coil,
inductance would be a better word, as this can be generated in ways other
than what would normally be termed a 'coil'.)

A coil is made of a wire.
Are "magnetrons" or simmilar device for yours transmitters?

Well, usually but not necessarily.

Magnetrons are microwave oscillators and impractical to build much below
1 GHz.

Magnetrons have nothing to do with coils of any kind.

You are babbling.

Jeff is right, inductance would be the correct term but you want a coil made
of wire...Well what do you call a strip line used in VHF & UHF & beyond in
Ham Transmitters...I'm referring to a straight piece of wire (strip line)
that is not a coil & has no turns....Now you have your answer, it is
possible & is done with no coils...Howard K0ACF

The word is inductor. At certain frequencies inductors take the form of
coils. At high UHF the inductors take the form of hairpins (aka Bobby
pins) a half of a loop.
