and auto-correction for R820T tuners. -Updated TunerModel and TunerViewPanel to add 2 new columns to display the current tuner's PPM setting and (when available) the measured frequency error averaged over 5 second intervals provided by certain decoders (e.g. P25 C4FM and LSM). Frequency error value from P25 decoders is provided from the Costas Loop PLL once 2 or more P25 message sync events have been observed in a short period. -Updated R820T tuner to auto-correct PPM when measured frequency error exceeds the +/- 0.4PPM threshold for a period of 30 seconds or more. Feature can be enabled/disabled by user in the tuner editor panel. Resolved several issues with P25 C4FM/LSM decoders that was impacting performance related to channel misalignment from tuner PPM offsets.
