Echo Link

KARS Echolink

Echolink® allows licensed Amateur Radio operators to communicate with one another using Voice-over-IP (VOIP) technology. The program allows for worldwide connections.®

You can access the KARS gateway through our 2 meter Repeater on 147.375 Mhz +, using a PL of 156.7. The KARS node is 249466.

Echolink® is configured to accept commands thru the local repeater using DTMF tones (Touch Tones). These commands are used to enable or disable the link and to connect or disconnect from another node or repeater.

To establish an Echolink® connection, perform the following steps:

– It is recommended that you first identify your station on our repeater and that you are attempting an Echolink® operation.

– To activate the DTMF pass thru; key a 1802, drop the carrier, listen for the controller to announce “Echolink Active”.

– You can determine if the Echolink gateway is operational by keying a * DTMF tone. The gateway node will respond with status information.

– once active, key the transmitter, then key in the node number of the station to which you want to connect. Now drop the carrier and listen for Echolink® to announce the connection. If the link was not successful, key a ** to disconnect the gateway node.

– Following a successful connection, announce your presence on the linked node by calling CQ, etc.

– During a QSO using linked repeaters, let our repeater tail completely drop before transmitting to avoid any timeout problems.

– At the end of the QSO, disconnect the link by keying a *** DTMF tone. The Echolink gateway will respond with confirmation that the link has been disconnected.

– The following is a table of basic commands to use on our Echolink® node.
