Echofriends by EI4JR, for Echolink
EchoFriends is a simple to use Windows XP utility that allows 10 of your favourite friends to be just a click away.
There is a Stay Connected function which is quiet handy if you have a poor internet connection as the selected station will be re-connected.
Try it, it's very good not only for poor connections but for a major links that need to have all its stations connected 24/7.
