Fast scan TV (FSTV) and slow scan TV (SSTV) are modes used to send pictures or images over the radio. SSTV is generally used on the HF bands and can only send a still picture due to its low data rate and bandwidth. FSTV on the other hand is generally used on the UHF bands and can send a moving picture. Recently several HT manufacturers have produced handheld radios with built-in cameras and screens for use in this mode.
