P25Link

History

  • P25Link was first conceived around December, 2017.

By the end of January, 2018 a sync HDLC to async HDLC board begin to be developed by Bryan W9CR and Juan Carlos KM4NNO. An ambitious project that will be the evolution form P25NX.

  • On October 10, 2019, a Bridge code between P25NX and P25-MMDVM was released for testing on talk group 10203. The bridge is based on Perl. Later, by April 2020, a dashboard and more talk groups were added.
  • During June 2020, the first public release for code that replaces the old P25NX C# Code been uploaded to github. The code was completely written from scratch using Perl.
  • By October 24, the first .deb package was released.
  • On March 29, 2021, Juan Carlos KM4NNO made an attempt to relocate the Bridged TGs from 10100-10303 to the 1050x range, which was not aceptable for Jonathan G4KLX who decided he does not want any crosslink to P25NX so there are no Bridged TGs in the P25Clients/P25Gateway/P25Hosts.txt file on github as he denied to update his github repo.

P25Link in a nutshell

P25Link Perl code talks to Quantar repeater by a HDLC card Or a Cisco router using STUN (serial tunneling). It also connects to P25NX network using a VPN managed by the Cisco router and exchange data with other systems running P25Link code or P25NX code. All this data is exchanged using Multicast UDP frames. To connect to P25-MMDVM reflectors, it establish an UDP connection with the linked reflectors.

Cisco configuration

The best way to go for P25Link is to follow W9CR wiki: Allstar®_and_P25_on_Quantar

For those that prefer to go with P25-MMDVM features only, here is an example configuration. Please don't copy this blindly, it is not a turn-key/copy-paste solution.
