Here we will look at the characteristics of radio waves as far as is required for the design of radio communication equipment. We will explain the methods of processing radio waves and the thinking behind it, and gain an perspective on the subject. As of technology has developed, equipment that utilizes radio waves such as television, mobile phones and so on has been introduced, and now radio waves are present all around us.
Amateur television ATV is the transmission of broadcast quality video and audio over the wide range of frequencies of radio waves allocated for radio amateur Ham use. Ham TV stations were on the air in many cities before commercial television stations came on the air. ATV includes the study of building of such transmitters and receiversand the study of radio propagation of signals travelling between transmitting and receiving stations.
Wait a minute. Everybody with a CB radio is automatically deemed to have one. Including the FCC, which long ago got tired of licking stamps to send out actual licenses.

In electronics and telecommunications a transmitter or radio transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating currentwhich is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves.
Hams use a variety of frequencies for communications. Non-hams can " listen in " via their own receivers or radio scanners. Hams are able to use many frequency bands across the radio spectrum -- these frequencies are allocated by the FCC for amateur use. Hams may operate from just above the AM broadcast band to the microwave region, in the gigahertz range.
Includes RF from broadcast antennas, portable radio systems, microwave antennas, satellite, and radar Kelly Classic, Certified Medical Physicist. Electromagnetic radiation consists of waves of electric and magnetic energy moving together that is, radiating through space at the speed of light. Taken together, all forms of electromagnetic energy are referred to as the electromagnetic spectrum.
I'm happy to answer any ATV questions from licensed Radio Amateurs so please always include your call letters in the email. Licensed Amateur Radio operators can transmit live action color video and sound to other hams easily on the MHz and up Amateur bands. Check out all the fun applications and technical info on our web site.
