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 receivers , and the study of radio propagation of signals travelling between transmitting and receiving stations. ATV is an extension of amateur radio. SSTV is a method of transmitting still images over radio, when it is not possible to send video. In North America , amateur radio bands that are suitable for a television signal wide enough to fit such a signal are higher in frequency than VHF broadcast TV.
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. For higher power and greater DX add a linear amp - see the transmitting section below.

We see very few if any picture artifacts using our current format. I plan to share more on signal formats in a future article on our blog. We are both using HD Digital Camcorders as our primary video signal sources and p monitors to display our received signals. Early on, I decided to build a Transceiver like a setup.
