![]() ![]() The repeater must be within the range of the transmitting node, only then the repeater may be able to re-broadcast the signal to multiple nodes. The repeater station is place on top of hills, so that it can receive maximum signal from a node and re-transmit to single or multiple nodes with less distorted signal. In other words a repeater extends the range of the signal being transmitted. A radio repeater repeats the transmitted signal to wider range, even over several 100 KM, which ensures that the receiving party will receive a clear signal. To avoid this kind of issues we go for a radio repeater. These obstacles could potentially reduce the range of the propagated signals, thus the person at the receiving end may hear broken signals. For example: Person ‘A’ can talks through walky-talky to person ‘B’, but person ’B’ can’t reply simultaneously and vice versa.ĭuring propagation of modulated signal from walky-talky ‘A’ to walky-talky ‘B’, there could be obstacles between them, such as mountain, buildings, trees, etc. A walky-talky is a half-duplex communication device, which means the communication takes place in one direction at an instant. ![]() Here we are taking walky-talky as an example. NOTE: Follow the strict rules and regulation implemented by your local and country government before proceeding with this project. This may be used for short distance communication when you are on a camp or use as an intercom or some similar applications. ![]() In the end you would be able to build a micro repeater station for the proposed full duplex communicator design in this article. Word Repeater Audio how to#In this article we are going to see what radio repeater is, how it works and how to build one in a hobby lab. ![]()
