[2] This allows for many more channels, accommodating fast scan television , wideband digital modes, and point-to-point linking, which may not be permitted on 2-meter and ...
ATV operation in the 70 cm band is particularly popular, because the signals can be received on any cable-ready television. Operation in the 33 cm and 23 cm bands is easily augmented by the availability of various varieties of consumer-grade wireless video devices that exist and operate in unlicensed frequencies coincident to these bands.
