Denny Sheirer	0d886c272e	#1067 P25 Phase 1 C4FM/LSM decoder redesign. (#2294) ... C4FM now uses SIMD differential decoding and soft sync detection. LSM updated with soft sync detector and retains original Gardner error detector. Adds new QPSK symbol view in the now playing channel tab. Restores PLL error driven tuner Auto-PPM feature. Deletes the demod viewer GUI application and all instrumented decoders Updates DMR to send soft symbols to new symbol view in Now Playing.

Denny Sheirer	b3b2e74688	Resolves #663. Updates P25 phase 2 Decoder to detect PLL lock errors for +/-90 and 180 out-of-phase. Adds support for broadcasting phase 2 channel frequency error calculations to support tuner auto-correction for frequency errors. Removes adaptive PLL bandwidth support from Phase 1 and uses a fixed PLL bandwidth for both phase 1 and phase 2 decoders. Updates the Phase 2 symbol timing gain with results from extensive testing of PLL bandwidth and symbol timing combinations. (#666)	2020-02-22 20:09:24 +00:00
