Why are radio signals not transmitted directly by electromagnetic waves?
The question's meaning is mysterious. Radio signals AREelectromagnetic waves,specifically those in the band of frequencies/wavelengths known as "radio waves".That's exactly what is physically transmitted. Between the transmitting antennaand the receiving antenna, the energy of the radio signal, and the informationencoded in it, travels in the form of electromagnetic waves.
How are radio television signals added to EM radio wave?
The process of adding information onto a bare radio wave is called "modulation". It means changing something on the wave ... either its amplitude, frequency, or phase, or actually turning it on and off ... according to a pattern that the transmitting person and the receiving person have worked out and agreed to, so that when the transmitting person makes changes to the wave, the receiving person can figure out what those changes mean.
Telemetering is a method of?
Transmitting the readings of instruments to a remote location by means of wires, radio waves, or other means. Also known as remote metering; telemetry.
Does a wireless router broadcast or transmit radio waves when no computers are connected or does a router wait for a signal from the computers wireless adaptor before transmitting and radio waves?
It has to always be broadcasting radio waves otherwise no devices will ever find the router.
What are radio waves and what are they used for?
Radio waves are generated and modulated with the transmitted information at the transmitting station and radiated by its antenna. These radio waves are picked up by the receiver antenna, filtered from all the other transmitted signals, detected and demodulated by the receiver to recover the transmitted information.
What is a palindrome transmitting radio waves?
radar
What type of energy transfers information from a radio station to the radio?
RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.

Is the radio a source of the waves?
The source is the RF current in the transmitting antenna.

Who invented Radio Waves transmission and receiving phenomenon?
Nikla Tesla in 1881.

What is space wave propagation Give two examples of communication system which use space wave mode?
In which radio waves travels in earth's troposphere from transmitting to receiving end is space way propogation Eg: television channels, VHF,UHF
What does a antenna do?
its collects data from space. It is a device that converts electrical energy into Radio waves or TV waves sending them out or receiving them.
Which type of electromagnetic radiation is useful in communications technology?
Mobile phones use electromagnetic waves with frequencies in the microwave range.
