release news – Go2signals 23.2
go2key - DMR ARC4 key finder
Digital mobile voice radios (PMR) are currently of great interest due to their worldwide use, especially in security-relevant environments. Most radios are able to use encryption methods to protect their user groups. In order to be able to listen to encrypted voice, go2signals offers the possibility of decryption in its decoders.Depending on the used encryption method, the required keys are automatically detected (e.g. DMR Motorola Basic, Alinco, Hytera Basic) or can be manually entered by the user. As one of the fi rst providers, PROCITEC now offers with this new release 23.2 the possibility to automatically detect the keys for ARC4 (e.g. Motorola Enhanced) encryption of DMR radios.
SIGNAL ANALYZER ENHANCEMENTS
SIGNAL INFORMATION DATABASE
In order to quickly access existing knowledge during the analysis and to compare the results with known signals, Signal Analyzer now offers an integrated database. Measured parameters are automatically used with this new feature, the Signal Information Database.Measured parameters are automatically used with the next new feature, the Signal Information Database. Filtering the database with the parameters
provides a quick indication of the signal type, its parameters and usage.
NEW ANALYZING TEMPLATE FOR MULTITONE (MFSK)
AUDIO PLAYER FUNCTION
SIMULATE DOPPLER SHIFT WITH SOMO SIGNAL GENERATOR
In the case the sender or receiver of a signal are moving, the center frequency of the signal shifts according to the difference speed (Doppler shift). SOMO is now able to simulate this effect with different parameters to each generated signal for a maximum of flexibility. Shape type, period, amplitude and initial phase are parametrizable.
MARK CELLS USING USER-DEFINED RULES IN RESULTVIEWER
Cells in ResultViewer result table can now be colored based on user-defined rules, depending on the column and values in each field. This gives the operator the opportunity, for example, to highlight important content and thus make it easier to see.
RESULTS ARCHIVE WITH LONGER STORAGE TIME
go2MONITORs database stores different types of results like classification parameters, demodulated bits, decoded content (e.g. text, voice, files), post-processed results etc. To avoid storage overflow, automatic deletion can be parametrized. Marking results with an “archive” flag, they are now stored in a result archive with different, longer storage time.
BULK-EDITING WITH RESULTVIEWER
For manual post processing and signal parameter adapting, ResultViewer has the possibility to edit automatic generated result. With this new release it is now possible to edit multiple results at once using general details tab (bulk-editing).
SETTING A HIGHER LIMIT OF LINES PER TABLE PAGE
To keep the time for a display update short and thus the usability high, the number of results shown in one table page in the ResultsViewer is limited to 1000 lines as default. On computers with sufficient performance and a fast database connection, this default can now be set to higher values in the settings dialog.
The signal classification in the go2signals software works both in the wideband input with many parallel concurrent emissions and in the narrowband channel, processing only one emission. In both cases the classifi er is able to track signal behavior, measure modulation type and its parameters and even detects known modem types.
With the previous version we started to support signals with very large bandwidths not only in the modem classification but also in the modulation classification. With this release, OFDM classification has been extended to work on signals with a bandwidth of up to 12.5 MHz.
- Add new modem classifier for CIS 60
- Add new modem classifier for CIS Akula
- Add new modem classifier for Link 22
- Enhance classification of OFDM signals up to 12.5 MHz bandwidth
DECODER AND DEMODULATOR ENHANCEMENTS
One of the core functions of go2signals is the demodulation and decoding of different modem signals. With over 350 modems and modes, a wide range is already available to the user today. To keep up with the evolving signal world, we have also added new functions with this release.
FSK discr.: Parameter shift is now interpreted as distance between neighboring frequencies instead of distance of the outer tones

UPDATED DECODERS TO PYDDL
- Clover II / 2000
- „Source“ result field now contains information if the result originates from a manual channel, including the user name of the user who created it, in the form of „[Manual:username]“
- New function allows NB-channels to be assigned to AMT tasks. In that case, all results from those NB-channels will be marked as results from the assigned AMT-Tasks
- Matching results with recordings is no longer an internal function of the ResultViewer. The whole process is automated and performed in the system for all results. Result flag „Result matching“ is provided to check if this matching has been performed or not
