The Transpeater III, from Transcrypt Int'l. fits in the palm of a user's hand and can convert portable or mobile radios into a temporary repeater system in minutes, benefiting users by extending the range of radio operations. It can also be used to connect two or three normally incompatible radio groups when used in relay mode.It is ideal for military, police, fire, and rescue personnel in situations when tactical operations move outside of normal operating range, to remote or isolated locations, or when the terrain interrupts radio communications. Range extension can be critical in situations such as earthquakes and forest fires or even in cities where tall buildings can interrupt communications,
