Fast-Scan Television (ATV)

Fast-Scan Television, often known simply as Amateur Television and abbreviated ATV, allows amateur operators to send and receive live-action TV images very similar to those of broadcast TV.

Because ATV requires substantial bandwidth, it is only permitted at UHF and higher frequencies. This means that ATV is strictly a local communications medium, and DX is not possible. Amateurs wishing to exchange images with operators thousands of miles away should investigate Slow-Scan Television (SSTV).
