What frequency do two way radio use?
They are not always different. If the communication is between two radios directly, only one frequency is used. This is called simplex operation. It works fine because only one radio is transmitting at a time. When two radios communicate through a repeater to increase the distance, the repeater must simultaneously receive from one radio while retransmitting the signal to the other radio. A single frequency would not work because the repeater would only hear its own output. So, two frequencies are used. This is called duplex operation. The above information is partially incorrect. Simplex and duplex do not refer to how many frequencies are used. They refer to the way traffic (data and voice) are sent and received. The reason for different receive and transmit frequencies is for retransmitting (like stated above) and for satellite communications. Satellites receive on one frequency, then modify, amplify, and retransmit the signal on a different frequency to prevent bleedover.
