Who radios on 70 cm?

Licensed amateur radio operators are primarily active on the 70 cm band, which covers frequencies in the 430 to 440 MHz range. This band is used for a variety of communication types, including voice communications, digital modes and satellite connections. It is popular for local and regional exchanges, particularly with handheld radios and mobile facilities, as it provides good penetration in urban areas. Radio amateurs who focus on technical experiments, such as building their own antennas or exploring digital transmission methods, also regularly use this band.
