Duplex radio headset

What is Duplex ?

Duplex is that the radio has two frequencies per channel, often called a frequency pair.  One frequency transmits while the other receives. It is a concept used to help explain Half Duplex and Full Duplex.

Half Duplex – operates as duplex with two frequencies, but in this mode the radio must switch between transmitting on one frequency and receiving on another.  It can only do one at a time.

Full Duplex – full duplex uses two frequencies – one for transmit and one for receive – simultaneously.
