functionality so that the editor starts up without a channel displayed
and as each channel row is selected in the channels table, the editor is
updated with the channel configuration.
Likewise, the channel editor is now a channel event listener on the
channel model and will maintain channel state if the user changes
channel configuration in any of the external channel controllers like
the spectral display or the channel list.
-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
Resolves issue in tuner controller where controller was not releasing
sourced tuner channels, preventing re-tuning to other frequencies.
Resolves issue with channel timeout on MPT1327 monitored traffic
channels
Redesigned audio manager handling of audio outputs to ensure that only
one channel's audio can be routed to an audio output at a time.
Changed audio outputs to use the shared thread pool manager for
scheduled tasks, instead of creating a thread pool for each audio
output.
calculation when additional channels are allocated.
Incorporates tuner specific definition of overall usable bandwidth, so
that tuners like airspy can specify 90% of 10 MHz (ie 9 MHz) is truly
usable and the fringe 10% is unusable rolloff.
Also includes tuner-specific defining of the width of the central spike,
or a value of 0 indicates that the entire range is usable (ie airspy).
when tuner channels are allocated by the airspy. New method determines
the min/max requested frequency range and sets tuner center to the
center of that range, while limiting the total usable bandwidth to 90%
of the bandwidth, to account for rolloff of 5% at the upper/lower edges.
When a new channel is requested, if the channel fits within the current
center frequency and usable bandwidth, the center tune frequency is not
adjusted, to minimize the number of retunes on a busy system.
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
Adds Spectral/Waterfall display zoom feature with mouse dragging and
zoom window indicator.
Resolves issues with correct display and spacing of frequency labels and
tick lines display in the overlay panel.
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
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
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.
The CQPSK decoder is starting to take shape, but needs more tweaking and testing. It's not keeping a good lock on strong P25 signals. I have to add some more features to the intrumentation package to allow me to visualize the internals of the CQPSK decoder so that I can get a better sense of what needs fine tuning.
The CQPSK decoder may work for anyone that wants to sync the repo and run the build script.
Memory Fixes
Decreased the decimation process repeat timing so that it runs smaller work chunks more often
Decreased scheduled thread pool to 2 hot threads
Wrapped all scheduled thread pool runnables in try/catch blocks so that an exception doesn't kill the sample buffer processing thread and cause the buffer to grow unbounded.
P25 updates
Moved TSBK crc checks into the message framer so that message corrections don't occur after the message is constructed.
Added more functionality to the channel state for handling registrations and call events.
