Internet linking in amateur radio

Reviewed by • Digital Modes & Software Editor • March 2026

Internet linking connects amateur radio stations and repeaters over the internet, extending the reach of local amateur radio activity far beyond the typical range of a single repeater or simplex frequency. This technology allows hams to make QSOs with operators across continents, using their local radio equipment to access a global network. It bridges the gap between traditional RF communication and modern internet infrastructure, enabling worldwide amateur radio communication.

Operators use various Voice over IP (VoIP) applications and protocols to achieve this linking. Systems like the Internet Radio Linking Project (IRLP) allow repeaters to connect, forming wide-area networks for nets and casual contacts. Beyond voice, some internet linking applications, such as PSKmail, even enable email and basic internet data access over HF bands, providing valuable communication options, especially during emergencies. These tools expand the possibilities for hams to connect and communicate, regardless of propagation conditions or geographic distance.
