Here is a nice little link for the basics of EchoLink. This covers the basics and explains how it works and for those that have heard of it but were not sure what it is, this is a great place to start!! I think EchoLink has it's benefits, especially for new hams and those that do not have a radio. It takes a little effort to get it set up and comfortable navigating but if you have not yet, give it a try. They have free apps for both Apple and Android devices as well as software to load on to your pc.
