EchoLink software is a "Voice over Internet Protocol (VoIP)" application that enables licensed amateur radio operators to connect repeaters and individual stations via the Internet using a basic computer and a simple radio transceiver.   The program allows worldwide connections to be made between stations, or from computer to stations.  According to the latest information on the Echolink website, there are more than 170,000 registered users in 158 nations worldwide!

In situations where an amateur's installation of outdoor antennas is restricted by HOA convenants, Echolink is a viable alternative to enable amateur operation and still keep the HOA animals in their cage.   

There are Four Types of Echolink Nodes:

Node Type



Does not require a radio to link.  Uses a computer with soundcard, microphone, speaker, Echolink software and Internet connection


Uses the same equipment as the user node but adds an interface device and radio to link to other users or repeaters


Uses the same equipment as the link node to interface with a repeater.  This enables amateurs to use a repeater without the use of a radio.


The conference is a server function that enables the user, link or repeater node to connect to multiple nodes simultaneously.

N3CMH operates "Echolink Node Number 20273" through which, amateurs can connect by radio or computer to other Echolink nodes or repeaters around the globe.  

Connecting to the N3CMH echolink node is accomplished through the N3CMH UHF repeater.  The N3CMH repeater operates on 443.975 MHz (+5 Offset) using a CTCSS tone of 100.0Hz.  Licensed amateurs are welcome to use it provided they adhere to good operating practices.

If you are out of range from the N3CMH repeater, you may connect to the repeater by using another Echolink emabled repeater or through the use of the echolink application on your smart phone.
