Echolink Block Diagram
Echolink is a way for you to talk to amateur radio operators around the world using your PC. You connect to the Echolink server and it will bring up a list of the stations currently on-line and which ones are busy. Clicking on one of the listings will connect you to the station. If you connect to a repeater then your PC will act just like a mobile unit. You can use a dail-up line or DSL connection. Echolink software is free to download. You will have to get your license verified before you can start using it.
Here I'm sitting in my office in Hong Kong operating (operating as VR2LB) over Echolink on a repeater in The Woodlands, Tx. Due to the time change (9:00 in the evening) I'm talking to my friends going to work in the morning. Using Echolink you can keep in touch with your buddies back home if there is an Echolink Repeater near.
Echolink listing, there are currently 1843 stations on-line (it changes during the day etc.). It also indicates which stations are BUSY. There are different categories that are listed (repeaters, operators, etc.). Clicking on a listing will connect you with the Node (station or repeater).
Above is the Echolink screen indicated that I'm connected to W5MET-R (repeater in The Woodlands, Tx). It also has information about the connection etc. (this is programmed into the connection - some repeaters have little to no information).
I'm connected to NH7M repeater and there is also another link (WH6CYB). At the bottom is an bar graph which indicates audio levels. Use the bar graph to adjust your TX mike gain.
