What is P25 phase1? P25 Phase 1 was designed to use the same bandwidth as a narrow band FM channel, meaning they could be used side by side, and narrow band FM channels could gradually be replaced by P25 digital channels. Phase 2 is more spectrally efficient than Phase 1, providing two effective channels per 12.5 kilohertz bandwidth.
