specifically for P25 C4FM frequency tracking.
-Clarifies frequency change event naming and adds request/notitification
events for channel frequency correction type events
-Removes DC offset filter from P25 C4FM demodulator which was operating
independently of the AFC tracking component within the C4FM symbol
filter.
-Changed FCD tuner center DC spike buffer size after detecting that the
DC center spike was influencing the P25 C4FM filter frequency tracker
whenever the tuner's center frequency was changed to bring the channel
boundary within 3 kHz of the center spike -- set it to 5 kHz to provide
a better buffer.
-Updated spectral channel display to provide better indication of
automatic frequency control (yellow line) versus channel frequency
actions.
-Updated LJ1200Message to return proper address, reply code and site ID
aliases.
-Update LJDecoderState and LJDecoderPanel to properly reset after a
successful decode and to correct issues with gui label coloration.
-Improved handling of channel grants and call event logging
-Prevent traffic channels from changing to control channel state
-Change text on PDU Alternate Multi-Block to reflect trunking message
type
-Added interface for Adjacent Site messages and improved logging
overlay.
Minor edits to MPT and P25 config editors
Resolved issue with channels not accepting channel config changes
between restarts (processing chain was not being deleted)
Minor edits to P25 decoder state
Updated p25 decoder state to better track calls and call detects from
a trunked channel
Fixed issue with false detects on LDU2 encrypted call messages
Fixed Airspy channel allocation ... will allocate channels across the
entire bandwidth, minus 50 kHz on either end, and will not adjust the
center frequency if it's not needed.
Fixed traffic channel teardown -- traffic channels are immediately
removed now, without a fade delay.
AudioMetadata - updated flag is now reset upon copying the metadata
component.
-Airspy supported with 10 and 2.5 MSps sample rates. Additional
decimation may be added later.
-Spectral display updated to include smoothing and filtering options.
Note: the decimated output of a tuner channel from the airspy is
48,076.9 samples per second, versus the normal 48 kHz decimated rate.
This is 1.0015 times the normal rate and doesn't appear to impact the
decoders or audio processing. Therefore, no fractional resampling has
been added.
per-call recording and accurate state tracking.
Resolved issue with ThreadPoolManager limiting total number of scheduled
tasks (removed limiter - original intent is now OBE)
Updated ChannelState to better handle auxiliary decoder decode events,
so that when a fleetsync ident is at the end of the transmission, the
decode doesn't kick the channel back into a call state after it has
faded, causing static bursts and additional empty recordings.
Updated recording file name to include millisecond level precision, to
further avoid duplicate recording names
from Module so that Decoder can function independent of DecoderSTate and
DecoderState can more cleanly interface with other modules.
Resolves issue with LTR-type decoders where the AudioModule was
filtering demodulated audio buffers before the decoder received the
audio - demodulated audio buffers are now copied before creating
AudioPackets.
Note: Several of the decoders are currently non-functioning in this
commit. If you want the latest functioning codebase, please checkout
the commit prior to this one. All decoders will eventually be updated
with this new architecture.
Currently broken:
- Logging and recording
- Aux decoders (Fleetsync/MDC/LoJack/Tait)
- LTR/Passport decoders
Changes in this commit:
- Module architecture for decoders and components with central
provisioning by the DecoderFactory
- Transition from Complex sample stream processing to float buffer
processing for improved memory management
- Redesigned filter structures - to support buffers and streams
- Resolved several memory leak issues
- Universal sharing of the thread pool manager
- Added centralized audio management with call/user prioritization and
new gui with mute/volume controls
- Embedded audio metadata for eventual streaming support
- Redesigned ProcessingChain to support independent re-use
- Added new TrafficChannelManager to handle traffic channel allocations
- Traffic Channel pool size and Call timeout available in P25 and
MPT1327 configs
- Redesigned channel and decoder gui components
