PRC-120/E portable radio communication system is a HF (1.6 ~ 30 MHz) radio with the AME, USB, LSB, LSB-CW, and USB-CW modulation types. This radio includes an internal automatic impedance matching unit capable to operate with rod, wire, and wideband antennas.
Mission of the system is establishing the Morse/ voice/data communication in long distances using the ionosphere reflections. This type of communication can be established between moveable radios or with a fixed radio.
In addition, the radio can establish communication with various types of HF radios. Due to easy operation, proper keypad and display screen, and 100 preset channels, operator can control the radio easily and synchronize it with active networks.
PRC-120/E includes three power levels of 5W, 10W, and 20W to establish communication in short and medium distances considered for battery consumption management and radiated power control.
