* #576 Updates P25 activity summaries to list values in hex and decimal. Resolves issue with P25 explicit channel uplink frequency calculations. Resolves issue with Motorola base station id messages and traffic channel messages. Resolves issue with RFSS link control message control channel frequency calculations. Resolves issue with error when using recording tuners.
Resolves issue with the multi-frequency tuner source and P25/MPT1327 (#603) rotating channel frequency configurations failing to maintain lock
on the channel.
Converted the ChannelRotationMonitor from using identifier updates to
now using DecoderStateEvents so that the ChannelState can supply a
steady stream of channel state events to the monitor.
* Stores minimal main application window location and size/layout settings
to allow application to be restored to the same size/location on
restart.
* Adds column width monitor to all tables in application that stores the
column width settings in the user preferences so that on restarting
the application the table column widths are restored to the previous
widths.
* Initial work on add support for rotating control channels.
* Creates multiple frequency editor control.
* Updates channel source editor to allow user to select multi-frequency
configuration and add multiple frequencies.
* Adds full support for rotating control channels to the P25 channelizer.
Users define multiple frequencies in the channel source configuration.
The decoder monitors the state of the channel for a CONTROL state. If
the state does not stay in the CONTROL state for a user-specified delay
value, then the decoder rotates to the next frequency in the list. This
behavior continues until the decoder state once again changes to CONTROL.
This is NOT a 'scanner' feature.
* WIP on new P25 message framer.

* Adds new 1/2 and 3/4 rate trellis decoders. Still trying to chase
down why there is a sync pattern mismatch in the NID buffer queue.
* WIP - new p25 message framer works correctly now. PDU's are dectected
and decoded using the 1/2 and 3/4 rate trellis decoders. Packet
Sequences are assembled. Need to add a new packet sequence message
factory that can detect Motorola Auto Registration Service (ARS)
formatted UDP/ID packets and SNDCP command packets.

* WIP - finished updating most of the TSBK ISP and OSP messages. Converted
all messages to no longer include the NID (nac + dataunitID) so that
each message can simply hold the parsed values. Removed AliasList as
an argument to each message and updated all messges to use the new
IIdentifer and IAPCO25Channel interfaces.
Removed legacy TDU and LDU link control messages and replaced with a
single LinkControlWord class hierarchy.
P25 decoder state is not yet updated for the new message structure.
PDU message parsing is not fully implemented.

for moto link control messages for patch groups. Adds support for moto
ARS service, IPV4 decoding, and UDP/IP packets.
* WIP - finishes SNDCP packet data with header parsing. Compressed IP or
UDP headers are not yet supported, but are logged as such.
* WIP - converts all talkgroup identifiers to integers and updates
alias list to create a per-protocol map of talkgroup id's to alias.
Inserts a legacy talkgroup (ltr, p25, passport, mpt1327, mdc, etc.)
conversion utility to convert existing legacy (string) talkgroups to
new integer talkgroup format.
Creates an audio packet manager to insert metadata into audio packets
before streaming packets for playback, recording, and/or streaming.

the channel and decoder states.
Creates simplified channel metadata to maintain the now playing display.
Moves channel attributes (alias list, system, site, name) as configuration
identifiers in the channel state.
Many other refactoring and updates.
* WIP - numerous updates to push use of identifier collection throughout
the system. Updates the channel metadata and audio packet processing
logic. Implements a large portion of the P25 decode state processing.
Updates traffic channel management. Adds user preferences for timestamp
and identifier formatting, however doesn't add a user interface yet.
* WIP - initial implementation of user preferences editor window.
* WIP - updates preferences editor window to close and dispose window but
retain javafx event thread running.
* WIP - fully updates p25 decoder state and traffic channel processing to
use the new identifier framework.
Cleans up channel event processing and removes channel model as the sole
broadcaster of channel events. Channel processing manager now listens
for all start/stop events and requestors dispatch event directly to the
channel processing manager.
Resolves issue in airspy that was causing user interface to lock-up. The
issue appears to occur when the dongle is plugged into a usb port that
can't fully support the data rate. sdrtrunk now recognizes these errors
and warns the user that they should use another usb port.
* WIP - updates alias action manager and adds new talkgroup range alias identifier.
Updates playlist to incorporate a version number so that the playlist
updater only runs when needed, to update a playlist to the correct
version format.
Updates user preferences to use the google event bus to broadcast
preference update notifications to remove the need for listeners to
register directly on the user preferences instance.
* WIP - updates alias id editors to flag invalid values and moves legacy
alias ids to legacy package.
Updates event logging configuration to add traffic channel decode events
and decoded message logging. Removes binary message logging since that
is now replaced with demodulated bitstream recording.
* Removes system properties from user preferences. Preferences are stored
in the OS-dependent settings store (windows - registry)
* Updates MapService to use new PlottableDecodeEvent instead of monitoring
all of the decoded messages.
Updates Fleetsync decoder and related messages to identifier framework.
* Updates LTR-Net, Fleetsync and LJ1200 decoders to new identifier
framework and adds support for user preferences for formatting of
LTR-Net and fleetsync talkgroup identifiers.
Breaks LTR-Net messages into various message types and uses a new
message factory.
Removes alias list from message processing for ltr-net, fleetsync and
lj1200.
* Updates LTR-Standard messages to Identifier framework.
* Removes Plottable and IPlottable from codebase.
* wip
* WIP on MPT-1327 messages.
* Updates MPT1327 decoder to identifier framework and new traffic channel
manager. This decoder still needs to be updated with a new message
parser factory and a sync detector like what is now used for P25.
* Updates MDC1200 decoder and message to identifier framework.
* Updates Tait1200 and Passport decoders to identifier framework.
* Merges changes from master branch.
* Removes legacy alias support classes. Updates passport message processor
to only pass valid messages. Adds support to playlist updater for
converting passport mobile ids to become passport talkgroup values.
* Updates P25 decoder state and channel state to better track allocated
traffic channels. Resolves issue in timestamp manager for trackig
message timestamps. Resolves issue in airspy tuner that was causing
the tuner to stop sending samples to the application.

the transition of SystemProperties over to user preferences and consolidate
file preferences in one location.
Updates playlist manager to use the new file preferences and to use
default.xml as the new default playlist name, following conversion of
a playlist_v2.xml format to the new format.
In the near future, the user will be able to edit file locations and to
create/use other playlists.
Resolved an issue with all decoder states where not all identifiers were
being included in decode events.
only update the center frequency when needed and to place the set of
decoding channels adjacent to the right side of the tuner's center
frequency when the complete set of channels fit into the usable half
bandwidth of the tuner.
Adds 500 ms delay to initial registering for samples from all tuners to
feed the spectral display/waterfall. The existing approach of immediately
registering for samples was causing the airspy tuner to lockup
aperiodically. Investigation via debugger didn't show any application
thread locks ... usb master processor was continuing to service libusb
timeouts. Unable to debug internal airspy processes. Adding the delay
to startup seems to be a usable solution.
Updates decoder types to specify channel sample rate and pass/stop
frequencies for requested channels. Updates tuner channel source
managers to accept a channel specification for channels that are
allocated.
channel manager so that channel source requests can have a start
timestamp specified and the channel can be preloaded with samples from
the delay buffer. If no timestamp is specified, current time is assumed.
This feature requires corresponding updates to any decoder that wishes
to implement the timestamped sample preloading functionality.
buffers. None of the decoders currently support this yet, but the P25
will be updated to provide bitstream output for recording.
Renames the ReusableBuffer class to ReusableFloatBuffer for
consistency.
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.
Resolves an issue with the previous implementation where the tuner
editor was being refreshed repeatedly to update the lock state for the
tuner, rendering the editor almost completely unusable.
Now updates only the frequency control and the sample rate control to
reflect the tuner's lock state.
Adds capability to disable spectral display.
Adds right-click context
menu items to disable display and/or reenable display by selecting
another tuner.
Adds view menu items to disable spectral display or show a tuner.
Persists spectral display enabled state across application run sessions.
The C4FM and LSM decoders were issuing a PLL reset with each new
channel that was allocated, causing any existing decoding channels to
be disrupted. Decoding re-sync delays or inability to recapture the
signal for decoding would likely result as the tuner's overall PPM
caused misadjustment in the channel.
Resolved a NPE that was occurring in the FrequencyController for
sample rate changes.
sample rates.
Resolves issue in PolyphaseChannelManager responding to sample rate
changes in the tuner. The manager now recreates the channelizer when
needed if the tuner's sample rate has changed since the last time the
channelizer was used.
Updates the Tuner selection view to reflect tuner lock state. Updates
the tuner editors to enable/disable frequency controller and sample
rate controls according to the tuner's lock state.
Refactors a MixerReader instance from the RealMixerSource so that it
can be reused for both real and complex data outputs.
Updates RealMixerSource to use refactored MixerReader and use a default
sample rate of 8 kHz.
Updates the ComplexMixer to use the refactored MixerReader.
Updates the FCD 1/2 tuners for compatibility with the new ComplexMixer.
Removes several unused classes.
channelizer sub-system is functionally complete.
Updated the channelizer and synthesizer filter design methods to use a
Kaiser windowed Nyquist filter. Updated the synthesizer filter design
to use a new cutoff frequency of 105% of the channel bandwidth to
resolve a slight dip in the synthesized channel gain at the channel
union region.
Updated the 2 channel output processor to use a low-pass filter that
is designed for the runtime channel sample rate versus hard-coded 12.5
khz.
Testing and redesign continues ...
that is currently up/down converting the signal of interest, but the
synthesizer is not correctly combining the original two channels.
Some experimentation with the tap count for the channelizer indicates
that we can cut the tap count in half and still have decent decoding
on the P25 decoder when paired to an aligned channelized output. The
2-channel synthesized output decodes partially, but needs more work.
Resolved issue with channel gain in the channelizer that was making the
sample values so small that they were registering as zero when converted
from float to 16-bit int value in the complex wave recorder.
