Internet linking connects amateur radio stations and repeaters over the internet, extending the reach of local VHF/UHF signals globally. This technology allows hams to make QSOs with operators far beyond their radio's normal range, using Voice over IP (VoIP) to bridge distances. It’s particularly useful for mobile operators, those with antenna restrictions, or for linking nets across different geographic areas.

Operators can find various software tools for internet linking, including clients for popular systems like EchoLink and IRLP, which connect individual stations or repeaters. There are also specialized applications such as Winlink and PSKmail for sending email and data over HF bands, even without a direct internet connection at the radio site. Programs like AllScan provide web-based control and monitoring for AllStar nodes, while EchoMac offers Mac users access to the EchoLink network.
