318e6f3586 #39 WIP - changes tuner controllers to expose the frequency controller
and the channel manager in preparation for polyphase.

6e94d9ce51 #108 [WIP] Created new ThreadPool class with a static ScheduledThreadExecutor that is now shared by all components. Removed ThreadPoolManager from all classes. Consolidating into 1 pool seems to have reduced CPU usage by ~15-20%. Overall memory usage is also reduced. 2017-01-22 09:33:47 -05:00

218eeb1848 WIP #34 - more work on tuner model and view. Includes new tuner
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.

4be63d4b95 Work in progress.
-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

0951277915 Tuner Controller update to better handle automatic center frequency
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).

f4d8ea281d Initial commit of redesigned internal processing and audio management.
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

5f4e7652bd HackRF - final check-in. Changed all tuners to use the low-level API of the usb4java library to resolve limitation in high-level API that constrains maximum sample rate to ~2.0 MHz. Added console logging to logback. 2014-10-20 23:09:50 +00:00

fe8612b68f R820T Tuner Controller - expanded tunable frequency range to cover 3.18 MHz to 1782.03 MHz, although I don't currently have an antenna to test the lower HF frequencies.
- Resolved major issue where the tuner was only tuning half of the frequencies in a non-contiguous manner.

35a2cebe03 Converted frequency to long primitive type (from integer) in anticipation of HackRF support which requires frequencies greater than 2.147 GHz, which is the max hertz value that can be represented by an integer primitive. 2014-07-08 14:40:11 +00:00

a994611a4b Resolves Issue #13 - R820T tuner was not accurately tuning requested frequencies. Updated the setPLL() method use PLL divider and integral enums to do away with the rounding errors being induced by Java that were inconsistent with the same method in the C++ librtlsdr code.
Discovered that the setTunerFrequency() method was not using the IF Frequency offset when tuning -- corrected.

f0c2868cd4 R820T Tuner support added.
-Refined sample rate values for 2016 and 960 MHz rates, which were running much slower than advertised.
