EchoLink is a computer-based amateur radio system that allows licensed amateur radio operators to communicate with one another over the internet. Here are some details about EchoLink:
Function: EchoLink allows licensed amateur radio operators to communicate with each other using their computer, smartphone, or tablet. It can be used to connect to other amateur radio operators around the world or to local repeaters.
System Requirements: To use EchoLink, you will need a computer, smartphone, or tablet with an internet connection. You will also need a microphone or headset to speak into, and speakers or headphones to hear the other person.
Registration: To use EchoLink, you will need to register with the system and provide proof of your amateur radio license. Once you are registered, you can download the software and start using the system.
Modes of Operation: EchoLink can operate in several modes, including simplex, repeater, and conference modes. In simplex mode, you can communicate directly with another amateur radio operator. In repeater mode, you can connect to a local repeater and communicate with other operators through that repeater. In conference mode, you can join a group conversation with multiple operators.
Call Sign Validation: To ensure that only licensed amateur radio operators are using the system, EchoLink uses call sign validation. When you register for EchoLink, you will need to provide proof of your amateur radio license, such as a copy of your license or a call sign authorization.
Node Numbers: Each EchoLink user is assigned a node number, which is a unique identifier that is used to connect to other users. To connect to another user, you will need to know their node number or call sign.
Restrictions: While EchoLink allows licensed amateur radio operators to communicate over the internet, there are some restrictions on its use. For example, you cannot use EchoLink to contact non-amateur radio users, and you must abide by the regulations and guidelines set forth by your local amateur radio organization.
