Radio astronomy - Radio astronomy is the study of celestial phenomena through measurement of the characteristics of radio waves emitted by physical processes occurring in space. Radio waves are much longer than light waves.
Static (radio) - Static is unwanted background radio noise or jumbled waves that interfere with the detection of the desired waves. Radio waves from the background radiation of the universe were at first thought to be random interference, until their origin was discovered.
Microwave radio relay - Microwave radio relay is a technology for transmitting digital and analog signals, such as long-distance telephone calls and the relay of television programs to transmitters, between two locations on a line of sight radio path. In microwave radio relay, radio waves are transmitted between the two locations with directional antennas, forming a fixed radio connection between the two points.
Radio spectrum pollution - Radio spectrum pollution is the abundance of waves in the radio spectrum that cause problems for some activities. It is a form of light pollution, and of particular concern to radio astronomers.
Medium Wave Circle - MWC is the only UK-based club specially for radio enthusiasts interested in medium wave and long wave radio. Includes services provided, membership details, audio and video clips, photographs and information about publications.
Radio Transmission - Learn about the different stages of radio transmission, how radio waves are emitted, and the difference between AM and FM radio.
The Medium Wave Circle - United Kingdom based club specially for radio enthusiasts interested in medium wave and long wave radio.
