About

P25Link is an amateur radio project originally created to let you connect Quantar repeaters Astro TAC comparators and/or DIU 3000s to multiple amateur radio networks such as P25Link, P25NX, P25-MMDVM. It use the v.24 port on Quantar/ASTAC/DIU 3000, a Raspberry Pi 2/3/4 and a DVM-V24 USB Converter for V24 Equipment or a Cisco router 28xx or 29xx series as used for P25NX.

The main goals is to allow P25 amateur radio users to be able to connect to existing networks.

Due the Talk Groups limitation found on P25NX and because there seems to be no more development on it, P25Link was coded under Perl, being able to add more features. It is now possible to connect to P25NX talk groups and/or P25-MMDVM talk groups. Repeater owners can choose they want to connect using P25Link, P25NX network or P25-MMDVM for every TG.
