What is required before using the EchoLink system?

Because EchoLink allows users to transmit over amateur radio frequencies via internet-connected repeaters, it is legally required that all users hold a valid amateur radio license. To enforce this, the EchoLink system requires new users to register their call sign and submit digital proof of their license before their account is activated. This verification process ensures that unlicensed individuals cannot use a smartphone or computer app to illegally broadcast over amateur radio airwaves. The software itself is free, meaning there is no license to purchase, and it is available to all license classes, including Technicians. Therefore, options suggesting fees, specific license classes, or mandatory training courses are incorrect.
