Changes to model, view and controller components and updates all gui
editors. Removes the configuration panel and tree and replaces with 3
new panels. Updates playlist.xml to a new playlist_v2.xml format.
Removed frequency change listener framework from tuner so that the tuner
controller handles all frequency change interaction.
Updated tuner view to allow selecting tuners for main spectral display
and/or launching a new spectral display by clicking in the tuner table
cell.
configuration and tuner configuration assignment editors. Beginning of
tuner editor panel rework. Removes most of the remaining JTree
configuration pieces. Updates the settings manager to load and save
tuners and refactors all of the tuner configuration management out into
the tuner configuration model.
saturation.
Each tunerchannelsource was sharing a thread pool and as the processing
load increased, the thread pool was not expanding and the processing
tasks were backing up, causing the buffers to grow with unprocessed
data.
Changed so that each tuner channel source is handed a thread pool to use
for processing incoming sample data. Processing chain maintains the
thread pool and starts the channel source. This allows traffic channels
to reuse the thread pool across multiple iterations.
-Started work on new channel editor channel viewer/controller
-Removed a number of unused buffer package classes
-Moved automatic frequency control to be a module and removed special
handling
-Added IUnfilteredRealBufferListener & Provider interfaces
-Completely removed the ResourceManager class
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
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.
Changed C4FM symbol filter to reset frequency tracking values when the tuner's frequency or PPM values change.
Moved all frequency control pieces into the source.tuner.frequency package.
Converted to use float primitives and to keep samples in buffer format until the sample rate is decimated to 48kHz.
Added new non-recursive, CIC decimation filter -- untested
Updated sound card/mixer input source management. Now testing for mono/stereo support for each card and limiting channel choices accordingly. Separated the mixersource into a ComplexMixer and and SimplexMixerSource. The ComplexMixer is used for sound card based tuners like the funcube. The SimplexMixerSource is used for demodulated sound card inputs.
Interfaces for sample handling - standardized on using 'Complex' to indicate I/Q samples and 'Simplex' to indicate demodulated float samples. The processing chain now accepts either a decimated (48k) list of complex samples from a tuner channel source, or a 48k simplex buffer (array of demodulated float samples).
Resolved issue with HackRF tuner not applying tuner configuration information.
NOTE: only the gui components and settings handling have been implemented. Actual recording playback is not yet implemented.
Partial checkin of initial P25 decoder development.
NOTE: P25 decoder is not yet functional.
