A radio transmitter changes most of the electricity that it gets from a wall outlet or a battery to heat. A small portion of it becomes energy that radiates out from the transmitting antenna and can be detected by receivers some distance away.

Carrier power is the power that comes out of a transmitter and goes to the transmitting antenna at the moment when no information is being added to the transmission ... no music, voice, sound, picture, data, noise, hum, no nothing. Only what they call a "bare carrier". There are different methods of adding information to the carrier, called "modulation". Some of them change the instantaneous power of the transmitter, others don't. Examples: AM rapidly varies the transmitter power. Properly adjusted FM doesn't.
The radio transmitter is the electronic device that generates a radio signal, adds information to it (sounds of music, news , sports, weather etc.), amplifies it to a comparitively high power, and couples it to an antenna so that it can be radiated out to receiving devices at considerable distance. Exactly the same basic functions as the section in your cellphone that connects your called number and your voice to a cell tower some miles away.

that depends mostly on the transmitter power and the square of the distance from the transmitter.
The output of a radio transmitter is ac power at a radio frequency, designed to run into a load with a specified resistance, often 50 ohms.

Mühlacker radio transmitter was created in 1933.
Mühlacker radio transmitter ended in 1945.
Vakarel radio transmitter was created in 1937.
Ingøy radio transmitter was created in 2000.
Raszyn radio transmitter was created in 1949.
There are three main properties that make electricity work: voltage, current and resistance. Toys are controlled by Radio active element such transmitter, receiver, motor, power source and antenna.
Because a pager is just a radio receiver and not a radio transmitter. A cell phone is both a receiver and a transmitter. A receiver uses much less battery power than a transmitter does. And because a pager's disposable alkaline battery holds more power than a cell phone's rechargeable battery.
