|For licensed hams, EchoLink®
software opens up new possibilities for communicating around the world with
other amateurs. Your PC links you or your local repeater to any of
thousands of other stations over the Internet.
There are several different ways you can use the EchoLink software. You can set
up a "simplex link" in your shack, with a VHF or UHF transceiver
connected to your PC, to allow anyone in range of your station to communicate
by voice with any other EchoLink station around the world.
Or, you can use the PC's microphone and speakers and remotely connect to any of
more than 2,000 different repeaters that have EchoLink capability.
The station-list screen keeps running tabs on who's currently on the
system. Stations which have recently come on or off are noted
separately. Sort the list any way you like. You can set up any
number of "alarms" which will sound when your favorite stations come
In Sysop mode, EchoLink connects to a conventional FM transceiver using either
custom-designed linking interface boards, or
general-purpose digital-mode interfaces. You can even build your own interface from
junk-box parts. The board connects to your computer's sound card and
Virtually any type of Internet connection may be used with EchoLink.
Custom settings allow you to tailor EchoLink to
compensate for older computers or slower Internet connections.
The program includes a number of important security features, such as the
ability to restrict access by country, to help comply with your nation's
third-party traffic or reciprocal operating rules.
