![]() Calls to any ham are routed to their last known D-STAR repeater and you will not have to know the location of the person you want to contact. Ham radios establish links between D-STAR repeaters by entering call signs into their D-STAR radios. D-STAR repeaters are connected to the D-STAR system through gateways. Therefore, it is not possible to transmit D-STAR signals through the regular FM voice radios and vice versa. ![]() The voice signals can be shared or relayed easily over digital networks because it is already digital during the transmission time. The repeater receives the digital stream of data and retransmits it as digital data. Communication occurs through streams of digitized audio over the air to another D-STAR radio or a D-STAR repeater. D-STARĭ-STAR is a complete set of digital communication protocols for individual radios on its own. You can use EchoLink whenever you cannot access a radio or when you are far from your home repeater. For EchoLink systems, users don’t have to have a radio because it can be accessed from the computer using the internet. When you are done, a disconnect message ends the sharing. The code will help identify the specific repeater system you want to use and the system in turn will set a connection and route your audio. If you want to connect to a system beyond your local repeater, you must manually enter the access code. In the IRLP and EchoLink systems, the links between repeaters and individual stations are controlled manually by system users. Repeaters can be connected over wide areas and long-distance using the internet through three primary ways: 1. This allows communication throughout the system without having to retransmit information from one receiver to another. Since the signal from the source station (called the “input”) has been strengthened, the signal can cover more territory with greater clarity.Ī repeater is a “duplex” in that it can simultaneously transmit and receive signals on the same frequency. The repeater then transmits the signal out over its coverage area on a different frequency. Since the repeater station is listening for its own frequency, it can distinguish between signals intended for it and signals that aren’t. The repeater itself receives a weak incoming signal, amplifies it, and sends it back to the same frequency on which it was received. The repeater network is an important building block in a larger network.
