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

Marconi.

So this:

"A Magnifying Transmitter is an advanced version of Tesla's tesla coil, a
high power radio transmitter. Often cited as Tesla's greatest invention,
the
Magnifying Transmitter consisted of three coils: an air-core transformer
plus a third coil operated as a grounded-base quarter-wave waveguide. In
Colorado Springs, Nikola Tesla constructed the first "Magnifying
Transmitter". From:

is not true?

That may or may not be a true account of a particular transmitter, but
has no bearing on the question that you asked, not being the first
transmitter to incorporate a coil.

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 todays transmitters "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?

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".

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".

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.

None of the above.

Modern recievers and transmitters contain coils but by no stretch of the
imagination could they be called Tesla coils.

No, that is utter nonsense that shows you know nothing about anything you
are talking about.

Tesla, you babbling idiot, and it is called a Tesla coil.

Yes.

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

Dunno.. Transmitting electricity through the air strikes me as
quite lossy, and if using a broad pattern to enable many people to use
it, the amount of recoverable energy vs what is transmitted would be
fairly small. A large amount would go off into space totally wasted.
If his method were actually practical, I suspect someone would be
using it by now on some scale.
There are enough loss just using a direct connection with wire.
I can light a florescent light bulb using the energy from my
HF mobile antenna. But only if I have the tube right next to
the antenna. Five feet away, fugettaboutit..

Exactly why the idea isn't used for anything much heavy duty than charging
a cell phone or a cordless toothbrush.

But system efficiency and losses were not something Tesla took into
concideration, nor was much thought put into how one whould charge
customers when they could have built the "receiver" end themselves
and obtained his electricity for free. Not a viable bussiness model.
