Radio is a special kind of long-distance electrical communications. It makes pos-

sible to send different signals such as dots and dashes of the Morse code (radio-te-

legraphy), speech and music (radio telephony), images of objects and films (televi-

sion). Radio helps us to maintain contact with ships, with aircraft in flight or a spa-

cecraft. Radio helps us to detect an aircraft flying high above the clouds (radio lo-

cation, or radar) and measure the distance to it. Space stations photographed, on a

command transmitted by radio from the Earth, the hidden side of the Moon and sent its pictures back to the Earth.

Daily radio programmes include lectures, reports and concerts. Radio is a powerful means of spreading knowledge.

1. Long-distance electrical communications c) The Morse Code

2. Radio Programmes d) Radio Today

Radio communication is the transfer of high-frequency energy from the transmit-

ter to the receiver without wires.

Radio is a device that transmits and receives signals and programs by electro-

magnetic waves. Since the process of radio communication includes transmission and reception of signals, the necessary components of radio are a transmitter and a

receiver.

The transmitter is a device that produces radio-frequency energy. The main parts of a transmitter are a high-frequency oscillator including an oscillatory circuit and

one or more amplifiers. In modern transmission electron tubes are used to amplify

currents and give greater transmitting range and better reception.

The receiver is a device that receives waves sent out by a transmitter. Radio rece-

iver demodulates these waves and they are heard as speech, music and signals.
