What is the difference between WALKIE TALKIE and TWO WAY RADIOS? Of course, there's a difference between a two way radio and a walkie talkie that's somewhat universal. Technically speaking, the 2 aren't an equivalent thing, although in some cases, they will be. to know the difference, we'd like to define the terms. A two way radio may be a radio which will operate two ways, that is, it's the power to both transmit and receive a radio wave , as against a radio which will only receive. A two way radio can either operate during a half-duplex or full duplex mode. Half-duplex allows the radio to transmit or receive successively but not both simultaneously. Full-duplex allows the radio to transmit and receive at an equivalent time. A two way radio is additionally commonly called a transceiver, because it can both transmit and receive radio communications. In either case, the radio operates two ways; it can send and it can receive. A walkie talkie may be a portable two way radio, particularly one which will be held within the hand. this sort of radio, also referred to as a handy talkie, handheld transceiver or HT, allows you to speak on the radio while walking around, hence the name walkie talkie.
