What is a two way radio? Two way radios are communication devices that are designed with half duplex channel. This restricts each radio to transmit frequencies and signals one at a time. You cannot switch on both radios in a set and attempt to transmit at the same time. The mechanics of using the walkie talkies to speak to each other is done by pressing a button, which is known as the PTT switch, and then you start talking. Once you are done, the button is released to end the transmission.
What are other uses of two way radios that will encourage one to buy and use them? Very often, they are compatible with each other across brands or makes. You can even communicate with similar radio devices that are mounted on vehicles or in radio base stations. If you do not wish to carry them in your hand and have to hold onto them while speaking, modern technology has also allowed add-on transmission devices such as microphones and ear pieces. And as such products cost very little money nowadays, using two way radios has greatly reduced the cost of communication in places and industries which rely on them.

Not only is communication between two parties served well with such a device, it also makes use of the general shortwave range that is not as expensive in terms of the gadgets available that take advantage of the spectrum. It can thus be a cheap alternative to other similar forms of contact radios that might rely on a broader range.
