The transmission of broadcast-quality video and audio over the wide range of frequencies of radio waves allocated for radio amateur (Ham) use.

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. ATV is used for non-commercial experimentation, pleasure, and public service events. Ham TV stations were on the air in many cities before commercial television stations came on the air. Various transmission standards are used, these include the broadcast transmission standards of NTSC in North America and Japan, and PAL or SECAM elsewhere, utilizing the full refresh rates of those standards. ATV includes the study of the building of such transmitters and receivers and the study of radio propagation of signals traveling between transmitting and receiving stations.

ATV is an extension of amateur radio. It is also called HAM TV or fast-scan TV (FSTV), as opposed to slow-scan television (SSTV). SSTV is a method of transmitting still images over the radio when it is not possible to send video.
