Features and Improvements

General

• HDU added as a new product option including integration in the GUI, ResultViewer and the result database. FHSS emissions are displayed in all GUI components, stored in the database and displayed in the ResultViewer
• Triggered wideband recordings as a new task type in AutoMon. The recording can be triggered based on modulation type recognition, modem classification or signal energy
• Added FHSS emissions as possible triggers in AutoMon
• Wideband recordings in AutoMon tasks can be parametrized with multiple time ranges, including “daily” recording times
• Manual wideband recording can now be started/stopped manually in automatic mode
• Added new result field, “Transmission type”, containing information about sender transmission type (USB, LSB, FHSS,…)
• Database/Result storage location changed from version-dependent user directory to the version-independent user directory so that the results are not lost after software update
• Automatic database upgrade function added. Starting from the next release, each new software version will automatically update the database and the result data
• Removed version name from the installation directory name
• System requirements for Windows OS changed: Windows 10 or a certain patch level is needed in order to use the applications (see user manual for details)
• AutoCoverage functions is now included if the AMT option is enabled. It will work in configuration with only one receiver.
• Added various new predefined modem lists for specific use cases

GUI

• Stations View completely removed and replaced with the new Frequencies View
• Frequencies can be displayed as an overlay in the wideband spectrogram, ResultViewer Signal View and in the ResultViewer Time/Frequency display
• Displaying matching frequencies for one result in ResultViewer/Detail added
• New list of frequency ranges and a new demo database with HF frequencies (from Klingenfuss 2018, 8-10MHz)
• New “Select all/Unselect all” options in all Multi-select-combo-boxes (Advanced filter, Frequency overlays etc.)
• Entering frequency restrictions in the AutoMon wizard is not mandatory anymore
• Signal file import function added to import external signals to the result database
• Removed 3MHz Bandwidth limitation for the file/stream input (warning if real-time processing is not possible)
• Added check for the max. number of modems selected in a narrowband processing AutoMon task (warning if more than 20 modems have been selected, to prevent sub-optimal use)
• Map display component updated to the latest Marble version. Displaying overlays with custom place marks is now possible
• Improved GUI performance in case a decoder delivers results with high data rates (e.g. for TETRA, DMR)
• Removed obsolete decoder result display function “Text only”
• Automatic parametrization of audio demodulator takes also the modem recognition result into account (until now only classification result). For example, if APCO-25 is recognized, “Digital codec” audio output will be turned on.
• Improved performance for displaying other results as overlay rectangles in the ResultViewer, Signal View
• Simplified usage of audio player for demodulated audio files in ResultViewer
• Improved Advanced filter layout by adding collapsible frames for each filter group
• Improved AutoMon wizard, modulation type trigger layout by adding vertical scrollbars
• Improved Frequencies view performance for imports/deletes/group membership (2-3x faster)
• New parameter added for StreamSources.conf entries to decide if streams will be delivered through GUI or directly from streaming source to the components
• Improved validity check for time activation ranges in AutoMon wizard

APC

• Integration of patented DVSI vocoders: improved voice output quality for APCO25, DMR, dPMR and NXDN

  • Motorola SmartNet: added modem for signals with 4 kHz shift
• Support for FM modulated USB/LSB voice signal with nominal offset (e.g. “FM2” or voice inversion and FDM signals)
• DDL performance improvements for commands using the Viterbi algorithm
• Modems with invalid nominal frequency were not activated on input bandwidth change
• Fixed calculation of FSK2 energy scheme to avoid exclusion of some FSK2 signals (e.g POCSAG 512 Bd)

Remote Control Interface, Integration

• Changed TCP ports used for communication with the host or between components:
  • Main CMAS (as_controller) control port 51811 -> 36811!
  • SignalServer control port: 51814->36814
  • RCM control ports, 60000->36940, 60100->36950
  • RCM streaming ports: Range 61001-… -> 36400-…
  • APC-Controller control port: 51812->31812 (All APC ports moved correspondingly with -10000 offset)
  • For other internal port assignment, see ICD
• New remote control functions for easy-to-use implementation of streaming signals I/O
• Some field names changed without losing binary compatibility (FLD_IFSTREAM_IP_ADDRESS, FLD_IFSTREAM_IP_PORT)
• MSG_IF_STREAM message extended to support new capabilities and renamed in MSG_SIGNAL_STREAM (name change only, binary compatible)
• Changed cardinality for FLD_USE_TASK_ID in IF-Server Task-Info message
• Added new SignalInput type, “UDP”
• Changed behavior if FLD_APC_ID is missing in MSG_TASK_ADD for production tasks. Instead of taking the first object, the system will take the object with the most free re-sources (channels)
• New example, “OfflineAPC”, to demonstrate the usage of APC functionality from a command line interface

Bugfixes

• Fixed problems with running tasks if the IF-Server is almost full and no old data can be deleted. IF-Server will now stop all depending tasks in order to be able to free the storage space.

• Problems with GUI freeze during audio output on some computers solved
• Modems not suitable for usage in auto mon tasks are now disabled in AutoMon Task-Wizard, depending on the selected action type (decoding only or modem search)
• Fixed problems with missing classification result in GUI, narrowband channel, if the se-lected processing bandwidth is exactly equal to the channel bandwidth.

• Fixed problem with updating object name in the Resource-View if it was changed in the system
