Quick view of my 2 node single system Allstar and Echolink Ham Radio VOIP setup. This wasn't to hard to setup as long as you have some experience with Linux and can follow directions.
VOIP is a very low cost way to make contacts all around the world. No need to buy fancy radios (I know we all will anyway) or large antennas. A single radio setup can be up and running for less than $150.00 and internet connection.
