- Updates P25P1 C4FM decoder to use same pattern developed for NXDN. - Both share the C4FM symbol processor and equalizer. - P25P1 updated with Garner style timing error detector - NXDN filters updated to use a combined RRC and inverse sync filter all in one. - P25P1 replaces RRC with band limiting filter - P25P1 enhanced with dynamic PLL balance updates to combat multi-path fading, in addition to the sync detection training window. - Decoder PPM error reports now only sent after 2x consecutive sync detections to prevent tuner PPM corrections from noisy/isolated false sync detects. - Soft error correction added to both P25P1 and IDEN.
