i would like to try it, but the nearest node is over 50 miles away from my apartment, and I'm in a low spot.
I'm around 700 feet above sea level and hills all around me are 1000 to 1200 feet.
David I don't think you quite know what echolink is.
Echolink is SOFTWARE you install on your PC and it allows you to connect the software to amateur radio stations all over the world via INTERNET. The most popular activity is logging into echolink and then connecting to a REPEATER SYSTEM somewhere in the world, and essentially you become just another voice user of that repeater system.
Here's an example. Where I live, we have a repeater on 147.375 mhz that has a 75 mile radius. There are about 40 to 60 active users on it locally via their 2 meter radios. But we also have ECHOLINK connected to it, so no matter where ever you are in the world, you can login to ECHOLINK and then connect to our repeater which is N5UCF-L once you connect your echolink software to our repeater you become an active user. You'll hear all conversations taking place on the repeater, and likewise, you'll be able to press the PTT button in echolink and talk to US LOCALLY through your PC's microphone. Your voice will go out on the repeater (147.375) and everyone in a 70 mile radius of Gulfport, MS will hear you talking, from wherever you may be.
That is how echolink works, and its all free.
Introducing EchoLink all you have to do is register to become a user and prove that you have a valid amateur license. Once that's complete you will be able to connect to stations (both repeaters, and simplex links) all over the world.
You do not need to be anywhere near a repeater that has echolink on it in order to use it.
