No, a GRE PSR-800 cannot be upgraded to P25 Phase 2; while it was once capable of Phase 2 through an experimental firmware update, it only supports Phase 1, and later firmware developments indicated it lacks the hardware and firmware capability for Phase 2 digital trunking.
Why the PSR-800 cannot be upgraded to Phase 2:
- Outdated Capability:
Although there were beta firmware versions that added experimental P25 Phase 2 support, these were for a limited feature set (e.g., not supporting full TDMA voice, radio IDs, or priority talkgroups).
- Lack of Modern Features:
The PSR-800, as a legacy scanner, does not have the firmware or hardware to handle the advanced features required for P25 Phase 2 and other newer digital modes like DMR or NXDN.
