Please see EchoLink and the URI for more information.One nice feature of the WB2REM board is the second input for a control receiver. The URI is a USB-powered interface with a built-in sound chip that lets you connect a transceiver to your PC, with both sound and signalling, over a single USB connection. The custom-designed linking interface boards from WB2REM and VA3TO.1 EchoLink User s Guide Version 1.8 Jonathan Taylor, K1RFDBelow is a partial list of high-quality interfaces which are specifically recommended for use with EchoLink. The GPIO ports can be used as radio port PTT and COS signals to interface with the connected radio and also to radio port PL (CTCSS) detection signal from an EchoLink software allows licensed Amateur Radio stations to communicate with one. TheLinkBox software delivered with the R.Net Raspbian Linux is compiled with special Raspberry Pi GPIO support. Raspberry Pi R.Net node GPIO PTT.

The program enables worldwide connections to be made between stations, from computer to station, or from computer to computer. I also have an Ultimate Linking Interface ULI from WB2REM & G4CDY Soundcard to.4 Introducing EchoLink Congratulations on installing EchoLink! EchoLink is software that allows Amateur Radio stations to communicate with one another over the Internet, using voice-over- IP (VoIP) technology. 70We shall see how these buttons are used during ECHOLINK operation.

This option is appropriate if you do not expect to connect radio equipment to your PC to operate a repeater or link node. User Mode Choose User mode if you expect to use your PC to connect to other EchoLink stations over the Internet, using your PC's microphone and speaker to communicate. Mode The first choice you will need to make is whether you want to run EchoLink in User mode or Sysop mode. Each screen of the Setup Wizard is described in detail below. The Setup Wizard gathers enough information about your system to get you started using EchoLink. All of the information in this document is also available in the Help file provided with the EchoLink software package.5 Getting Started Initial Setup The first time you run EchoLink after installing it, the Setup Wizard will appear to step you through the basic setup.

Unless you have a specific reason to begin with different settings, choose the 'Import these settings' option. Import If you have previously used ilink on the same computer, the Setup Wizard offers you the option of setting up EchoLink the same way by 'importing' your ilink 26 settings. For more information about the types of interfaces EchoLink supports, see Interfacing (p. Be sure to select the correct port, and verify that the port is not already in use by another application. The list of COM ports shows COM1 through COM8, although not all 8 ports may be installed on your machine.

If you are planning to run in Sysop mode, put an -L or -R at the end of your call to indicate a 'repeater' or 'link', respectively (for example, K1RFD-L). The callsign must be at least 3 characters long and may not contain spaces or punctuation, except as part of a -L or -R suffix. If you have already registered, use the same callsign you used previously. Region Callsign: Set the callsign exactly as you wish to be registered with EchoLink. Settings If you have not previously used ilink, or chose not to import the original settings, you'll be asked to enter some information about your station.

Be sure to make a note of it, in case you need to re-install the software. Otherwise, select a password you can easily remember, and it will be assigned to you as you register. Password: If you had used EchoLink previously, type your original password here. If you are expecting to run in User mode, do not use a suffix after your callsign.

Examples: 'Ridgefield, CT', or 'Link to W2ABC/R, NYC'. This will appear in the list of available users. Location: Enter the location of your station, or a description of its function. Enter the name by which you wish to be called.

This information is used to select the nearest set of 'addressing servers' for EchoLink to use. You will be asked to indicate in which general region of the world you are located. This address will be used only if EchoLink Support needs to contact you, and will not be published or displayed anywhere.

During this time, the Station List area of the screen will be blank, or may display a message indicating that your callsign is being validated. This process may take several minutes or several hours, since each call is individually validated by hand. Callsign Validation If you have never used EchoLink before, the callsign you entered will need to be validated by the system before you will be able to access it. As you read this section, you may find it useful to refer to the section EchoLink Screen on page 37, which shows the layout of the EchoLink screen and the names of each of its parts. 37 Basic Operation This section describes how to use the basic functions of EchoLink.

Use the tabs at the bottom to select either Index View or Explorer View, depending on your preference. Connecting to a Station To connect to another station, find the station's callsign in the Station List. For more information about guidelines for callsign validation, see the Support section of the EchoLink Web site.

Another possibility is that a network 'firewall' problem is preventing your PC from receiving data from the remote station. The other station may have already established a contact with someone else, or may have just logged off the system. This can happen for several reasons. If, after about 30 seconds, you see the message 'Cannot connect' instead of 'Connected', it means that the attempt to connect to the other station failed. You are now in direct contact with the other station and you can begin conversing. After a few seconds, you should see the station's callsign and name appear near the bottom of the screen, and you should hear the 'connected' signal.

The space bar works as a locking 'push-to-talk' switch. Speaking Back and Forth Once you're connected, you can converse with the remote station as in an ordinary QSO. You may also be able to find solutions in the Support section of the EchoLink Web site.

See Preferences for details. You can also change the software so that the spacebar is held down to transmit and released to receive, more like a push-to-talk switch. If you prefer, you can click the 'lightning bolt' icon near the upper left corner of the screen, instead of using the spacebar. A red TX indicator appears on the screen whenever EchoLink is 'transmitting', that is, sending audio over the Internet to the connected station.
