Most are not even on P25. Last month's article, Why TDMA makes sense for P25, addressed the decisions by the Project 25 Steering Committee that led to the acceptance and adoption of a proposed technical path to an industry harmonized Project 25 Phase 2 two-slot TDMA solution. Phase 2 is more spectrally efficient than Phase 1, providing two … It won't start getting There is TDMA decoding Want proof? The frequencies can easily be received with an RTL-SDR, but a decoder is required to be able to actually listen to the voice. Support for newer P25 Phase 2/TDMA systems (a receiver is implemented, as of March 2015) Locate and track the locations of P25 mobile stations. Public Works stuff going on, but that's completely uninteresting and it I am on the right path, but it may just need some fine tuning.
