In AM broadcasting, the amplitude of the carrier wave is modulated to encode the original sound. In FM broadcasting, the frequency of the carrier wave is modulated to encode the sound. A radio receiver extracts the original program sound from the modulated radio signal and reproduces the sound in a loudspeaker.

A receiver that picks up waves that carry sound is called a radio. A radio sends the electric signal through speakers so the sound can be heard. Each radio station sends out radio waves of a certain frequency. A person changes a radio from one frequency to another to hear different stations.

Radio works by transmitting and receiving electromagnetic waves. The radio signal is an electronic current moving back and forth very quickly. A transmitter radiates this field outward via an antenna; a receiver then picks up the field and translates it to the sounds heard through the radio.

4 Golden Rules for Radio Communication: Clarity. Your voice should be clear. ... Simplicity. Keep your message simple enough for intended listeners to understand. Brevity. Be precise and to the point. Security. Do not transmit confidential information on a radio unless you know the proper security technology is in place.

RF is generated by a transmitter and detected by a receiver. The transmitter antenna turns electrical signals into radio waves, giving it the ability to travel long distances. The receiver antenna catches the radio waves and turns them back into electrical signals, which feed into a radio, television, telephone, etc.

Daniel Vecchiolla says the five C's of radio communication - conciseness, clarity, confidence, control and capability - also apply to leadership.

Radio waves from many transmitters pass through the air simultaneously without interfering with each other and are received by the antenna. These can be separated in the receiver because they have different frequencies; that is, the radio wave from each transmitter oscillates at a different rate.
