No special hardware or software is required to relay a transmission via an EchoLink node. Before using the system, it is necessary for a prospective user's callsign to be validated. The EchoLink system requires that each new user provide positive proof of license and identity before their callsign is added to the list of validated users. There is no cost for this service, and it ensures that this system is used only by licensed amateur radio operators. The software is written to run on 32-bit and 64-bit versions of Microsoft Windows. Another edition of the software runs on Apple mobile devices (iPhone, iPod touch, and iPad), and is available from the Apple App Store. Qtel is an opensource version of the software available in many Linux repositories. An Android version is available on Google Play and several other Android app repositories. In late...
