Echolink information “VR2VRT-L”

             Introduction

             Regularly radio amateurs around the world using Echolink possibilities of the link VR2VRT in Hong Kong.
             Thereby however connections remain to stand open, or do users not know which codes must be used. This  site will
             give explanation concerning Echolink and the codes used at VR2VRT-L.

             If there are still questions should remain, then I’m glad to give answers by e-mail: vr2vrt@yahoo.com or of course
             via my link (if I’m QRV).

             Echolink

             Echolink is a system that can exist with the following components:

             . The Echolink software.
            
. A computer. A server.
            
. An Internet connection between PC and server.
            
. A transceiver

             Echolink is a protected network. Access is only possible by sending a copy of your amateur license to the Echolink
             organization. Because of this, abuse is prevented.

             The “Echolink”' software must be installed on the PC.

             Each station has an unique number (the node number), these are linked with the Internet.

             The PC can make with this Node number a connection to a central server (there are servers in the US, in Europe and
             in Asia).

            These central servers working as a “ switchboard “ to make the connection with other PC's.

             Radio amateurs connect their transceiver to the PC with an interface (See the site “projects’ for the interface), and are
             working as local stations
(for example as a LINK or REPEATER, using mobile or portable rigs) with the possibility to
             make network connection via a transceiver with Echolink.
 

             Misunderstandings

             A broadly spread misunderstanding is the term “ Internet “ at Echolink. We only use echo link as a medium. Echolink has
             nothing to do with E-mail, WWW or whatever. The term “ Internet “ is used here only for the protocol (TCP/IP) which
             is only used for the digitalization of the speech.

             An “ Internet “ connection can be therefore also be wireless, for example by means of two 23 cm or 10 GHz routers.

             However, in practice, ADSL connections or cable connections are frequently used for international contacts.

             Why is Echolink a supplement?

             There are several arguments, digitalization of radio communication takes place everywhere. It is an application of modern
             techniques in combination with existing techniques for radio transmitting amateurism.

             This of course only applies if there are also transceivers in the game, if it concerns only connections between PC users,
             VR2VRT-L doesn’t like to use these kind of possibilities of Echolink.

             There are local “support transmitters” or “ needs “ with which portable or mobile users can come in the network.

             Radio transmitting amateurs who do not have HF equipment or don’t have the possibility to place an antenna, can make
             with their 2 meters or 70cm rigs world wide connections with amateurs, via a local repeater or a link station (gateway).

             What do you need?

             First of all, you need a transceiver with DTMF possibilities. With these DTMF codes you can dial the Node number
             (a type of Echolink phone number) from the amateur were you like to talk to.

            Furthermore it must be possible for you of course to make a contact with the gateway in your neighborhood
            (VR2VRT-L) to complete your connection.

             How do you make the connection?

             Let we start at the beginning, you didn’t make any connection with Echolink and with the station you want to make a
             connection. You know the Node number of the station, with whom you want to make the connection.

             You take your handheld or rig and press first “08” to check or VR2VRT-L is not already in connection with a other
             station, if the gateway is busy with an other station you can break in any time or wait till the QSO is finished.

             If the QSO is ended, and nobody is in QSO anymore, you can disconnect everybody by pressing “##” if needed.

             No you can dial the Node number of the station with whom you will make the contact, after dialing, Echolink will say,
             “connected”.

             Wait a couple of second’s before transmitting.

             Now you can start transmitting and give a CQ to the station you want to talk to, if this station is not QRV Echolink will
             tell you that it is not possible to make an connection. If he is QRV he will come with an answer on your CQ.

             After your QSO is finished you press “#” and the connection will be canceled.

             If you have friends somewhere in the world who like to talk to you, they can make contact with you via
             VR2VRT-L with dialing the Node number
405006, if he call you it is to hear on the frequency 144.887.5 Mhz.

             And hopefully you are also QRV at this moment on VR2VRT-L.

             What if I don’t know the Node number not?

             Try retrieving it from http://www.echolink.org

             What if I don’t want to speak with a non-fixed station, but will call an ordinary CQ?

             You can make also with random Echolink stations, Links or repeaters a connection.

             This can be:

        . Repeaters (recognizable with ' - R ' behind the call).

        . Link stations (these are simplex stations, frequency on 2 meters or 70 cm, recognizable with

        . " - L " behind the call (for example VR2VRT-L).

        . PC- users (these are people who make QSO's only via their computer).

             PC users have no suffix behind the call (example VR2VRT). Because you don’t know the Node number you also don’t
             have to key it in, only you have to press “00” for all Echolink stations or “01” for link stations or repeaters.

             At the end of your QSO press “#” and you are disconnected again from Echolink.

             Of course there are much more possibilities with Echolink as here described, you like to need more information about
             Echolink or will download the software than go the website link for a complete tour.
