Echolink

A program designed by Jonathan Taylor, K1RFD to allow amateur radio stations to communicate with one another over the Internet, using voice-over-IP (VoIP) technology. The program allows worldwide connections to be made between stations, or from computer to station, greatly enhancing Amateur Radio's communications capabilities.

There are several different ways amateur operators can use the EchoLink software. They can set up a "simplex link" in their shack, with a VHF or UHF transceiver connected to their PC, to allow anyone in range of their station to communicate by voice with any other EchoLink station around the world.

Or, they can use the PC's microphone and speakers and remotely connect to any of more than 2,000 different repeaters that have EchoLink capability.

In System Operator (sysop) mode, EchoLink connects to a conventional FM transceiver using either the custom-designed linking interface boards from WB2REM and VA3TO, or general-purpose digital-mode interfaces such as the RIGblaster from West Mountain Radio. Hams can even build their own interface from junk-box parts. The board connects the computer's sound card and serial port.
