In a nutshell, echolink is amateur radio software that utilizes voip (voice over internet protocol) to relay amateur radio communications from one node to another, anywhere on earth. Communications are established between a computer terminal or radio to another computer terminal or radio. The Pella Amateur Radio Club has chosen to have access to echolink through our repeater. The repeater is linked to a computer (below) at the n0mpm qth and can be accessed by any amateur radio operator who can connect to our repeater.
