The Basic Elements of Radio Signals and Modulation
The purpose of a radio signal is to carry information. In radio communications, two essential components make the propagation of a radio wave (which carries the signal) happen: a transmitter and a receiver. It is these elements that provide the signal the means to go from one place to another. Signals are modulated into radio

Two Way Radios : A Beginner’s Guide
A two-way radio is a device which transmits and receives voice signals through the air. They work somewhat like a telephone, but since they do not require a central network they can be used anywhere! With two way radios, two or more people can have a discussion no matter where they are — sometimes while

Using Broadband Technology for Mission Critical Train Radio Communications
If you live in or around a big city like Sydney or Melbourne, you will have traveled by train at some point in time. Most people would understand the basic concepts, like the signal is at green, the train arrives turning the signal red for a short period of time until the first train has

Ham and CB Radio Communication – A Basic Primer to Two-Way Radio
Radio communications have come a long way from the original concept derived by Marconi’s discovery of electro-magnetic radiation (radio waves). Marconi conceived that an electro-magnetic pulse, sent through the air, would create an electron flow (flux) when it passes through a non-ferrous metal source. Such an electron flow can then be amplified to create sound
