amateur television has gained popularity as hobbyists adapt inexpensive consumer video electronics like camcorders and video cards in
PCs. Because of the wide
bandwidth and stable signals required, amateur television is typically found in the 70 cm (420 MHz–450 MHz) frequency range, though there is also limited use on 33 cm (902 MHz–928 MHz), 23 cm (1240 MHz–1300 MHz) and higher. These requirements also effectively limit the signal range to between 20 and 60 miles (30 km–100 km). The use of linked
repeater systems, however, can allow transmissions across hundreds of miles.
