About two way radio
Clicks: 1218          Author:Anysecu
  • A two-way radio is a machine that can transmit and receive, unlike a broadcast receiver which only receives content. A two-way radio (transceiver) allows the operator to have a conversation with other same frequency setting users on the same radio frequency (channel).

    Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called two-wat radios, 2 way radios, FM transceiver, Handheld radio, walkie-talkies, handie-talkies, or just hand-helds.

    Two way radio systems usually operate in a half-duplex mode; that is, the operator can talk, or he can listen, but not at the same time. A push-to-talk or Press To Transmit button activates the transmitter; when it is released the receiver is active. A mobile phone or cell telephone is an example of a two-way radio that both transmits and receives at the same time (called full-duplex mode). It uses two different radio frequencies (channels) to carry the two directions of the conversation simultaneously.
