P25Link is an amateur radio project originally created to let you connect Quantar repeaters and/or DIU 3000s to multiple amateur radio networks such as P25Link, P25NX, P25-MMDVM, etc. It use the v.24 port on Quantar/DIU 3000, a Cisco router 28xx or 29xx series and a Raspberry Pi 2/3/4. It use the same router setup as for P25NX.

The main goals is to allow P25 amateur radio users to be able to connect to existing networks with full interoperability between them as one only network (when network admins allow it).
