Two-way radios, just like standardradios, receive radio waves (RW) over the air. Radios convert RW into sound.The defining characteristic of a 2WR, however, is the ability to also convertsound back into RW for transmission to another radio-receiver. A 2WR cantransmit and at the same time can receive a radio signal. It uses to differentradio frequencies to carry the two directions of the conversationsimultaneously.The antenna in a 2WR contains a setof electrons. When a radio transmission is received, the RW excite theelectrons and cause them to produce electrical impulses. For transmission, theradio's processor notes sound vibrations created by speaker's voice, itconverts them into an electronic signal which is then ready for transmission tothe radio transmitter. When the modulated frequency is sent to the antenna andthe proper electrons are excited, outgoing RW are generated; these RW can thenbe picked up by other radios within a small area determined by such factors asthe size of the antenna, the battery power of the radio, and atmosphericconditions.Some of today's radios also allowscanning. Scanning is the process where several channels can be checked to seeif anyone is transmitting on any of the scanned frequencies. When the scanningprocess detects that a channel is receiving a transmission with the same P.L.tone or Private line tone (In P.L. Mode, the radio's speaker will activate onlyif another radio is transmitting on the same P.L. Tone.) the radio will stopscanning, lock on that active channel and open up the speaker.Most modern 2WR allow use ofmultiple channels. To broadcast on different channels, the transmitter of theradio must be able to generate RW in several different frequencies, with veryminute fluctuations in each available frequency.It remains so in-demand because evenin the face of mobile phones and laptops, people still realize the great easeand accessibility of instant communication with a group of people. This defeatspushing in several phone numbers and waiting for everyone to either answer ornot accept the call.Whether it is for home, work, orplay; everyone and their grandmother will be happy if they were to find theirnew 2WR waiting. No matter what reason you or your family and friends have tocommunicate with one another, you will find that a 2WR is the best optionavailable. They come in handy in a wide variety of situations and their easecan never be replaced even by the more popular communication tools of today.
