EchoLink is software which allows 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, from computer to station, or from computer to computer.
The program runs on Microsoft™ Windows® 95 or above. It is offered as freeware and may be downloaded.
EchoLink is a full-featured software package with many important and useful features.
A Tour of EchoLink For licensed hams, EchoLink 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.
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 ring when your favorite stations come online.
In Sysop mode, EchoLink connects to a conventional FM transceiver using either the custom-designed iLINK interface boards from WB2REM and VA3TO, or general-purpose digital-mode interfaces such as the RIGblaster from West Mountain Radio. The board connects to your computer's sound card and serial port.
Virtually any type of Internet connection may be used with EchoLink, from dial-up to DS3. Custom settings allow you to tailor EchoLink to compensate for older computers or slower Internet connections
The program includes a number of important new 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.
If the bandwidth of your Internet connection permits it, EchoLink allows up to 10 different stations to be connected at once. This is especially useful in Sysop mode for running a roundtable on your local repeater, or allowing "listening" stations to be connected without blocking out others.
Extended DTMF commands allow stations to be searched or connected by callsign, or the status of any station to be queried. The program also includes a built-in Web server for remote control of EchoLink from any Web browser on the Internet .And can also be setup to accept DTMF commands via voice modem.
Floating" pop-up windows keep track of how many stations are on the system, along with detailed status about the current connection.
The toolbar allows quick and
easy access to frequently used
The four system setup screens are easily configured. Most everything is Automatically filled in except your personal information.
The Preferences settings allow how the listings are displayed, the connections that are allowed and your personal info file, the security settings as to the connections allowed the call signs locked out or the country prefixes accepted or denied and the signals menu designates the sound played when activity is detected
The receive audio is able to be controlled in many ways the easiest is the default VOX.
But the most reliable is COR / COS.
The transmit control on the standard interfaces is via the serial connection.
The DTMF commands allow a number of different operations. These are listed on the Echolink Control Sheet.
The Identification allows the default computer voice, internal CW, or a .wav file for your Connection Identification.
The options settings are for voice announcements of connecting stations or conferences and the time out settings.
The Web tab allows for remote control via the internet and/or voice modem.
Interfaces: If you are expecting to set up EchoLink in "sysop" mode, you will need a special interface device which connects your radio equipment to your computer. This device allows the computer to control the PTT function of your transceiver, and (optionally) to accept and process DTMF commands from the receiver. For maximum flexibility, EchoLink is designed to work with several different types of interfaces. Below is a partial list of high-quality interfaces which are specifically recommended for use with EchoLink.
WB2REM & G4CDY'S iLINK Board
This interface is available fully-assembled, or in kit form. The circuit was described in QST for March, 2002. VA3TO Enhanced iLINK Controller
This interface is also available fully-assembled, or in kit form, and can be used with other digital-mode software such as PSK31. RIGblaster from West Mountain Radio
Several models of these general-purpose digital-mode interfaces are available, all of which are compatible with EchoLink. Use EchoLink's internal DTMF decoder when using a RIGblaster. G3VFP iLINK / EchoLink Interface Controller
Fully assembled and enclosed, fully isolated interface designed expressly for iLINK/EchoLink. Can be used with other digital-mode software such as PSK31.
Here are some other interface options for EchoLink.
PY2JF Interface (from Brazil)
Hookup is very easily done with Shielded wires and mini phone plugs on the interface side and the proper connecter for your Microphone Jack and external speaker. There is even an option for a control receiver to control the system remotely.
And the Short Case just left and under the monitor is the link computer
