go2MONITOR ENHANCEMENTS
NEW FUNCTION: MULTI CHANNEL AUDIO PROCESSING
A common task is the parallel monitoring of analog voice signals on a large number of fixed frequencies. With this new release, go2MONITOR offers significant improvements in audio handling for this type of usage.

16 channel live audio listening and 30 min buffering for playback
For example, in addition to live listening, each audio channel has its own playback buffer for several minutes, which makes it possible to playback the audio in a specific area or from a specific position during further processing.

Replay selected channels at a selected position or in a defined time range
During replay from the audio buffer you get some new features like an additional squelch function, change replay speed (slower and faster) or activate skipping of silence.

New features like replay speed or additonal squelch
NEW OPTION: 32 AUDIO CHANNELS
With the new audio functions, there is now an additional article for go2MONITOR, the “32 Audio channels” option, which extends the software by 32 channels (select n times for more than 32 channels). These additional channels support the demodulation of LSB, USB, AM, FM or WFM with squelch function and are optimized for manual monitoring of audio signals on fixed frequencies. The demodulated audio signals are buffered for playback and can be recorded automatically or manually and saved in the results database.
NEW FUNCTION: TIMELINE VIEW IN RESULTVIEWER
With the ResultViewer in go2MONITOR, the user has the option of analyzing, editing or merging results and forwarding them accordingly to other systems.
A new feature for result analysis is the now available Timeline View. This view shows the temporal behavior of individual results and their relationship to each other, e.g. to recognize patterns of typical communication behavior or to identify frequencies used.

This enables a wide range of different analysis options, especially since the user can extend the structuring with his own scripts (editor in go2MONITOR included).

Example: Short customer script structuring communications
NEW: DARK MODE
In addition to light is now a new color theme dark available.

ENHANCED: GO2MONITOR OPERATOR
Since release 22.2, go2MONITOR offers the possibility to share the results and resources of a central used core software with additional configurable user workstations. This makes it possible to divide user tasks among different workstations (e.g. special workstations for special signals) or to configure small systems with multiple operators sharing a more powerful core go2MONITOR software.

Work with go2MONITOR and multiple workstations
The Operator workstation now include several Master UI features: Resource View, Emissions View (without Classify button) and recording symbols from narrowband channels.

SIGNAL ANALYZER ENHANCEMENTS
NEW: MSK ANALYSIS FEATURES
This new template enhances the FSK analysis template with additional measurement features specialized on MSK modulation. New features are differential phase I/Q display, the spectrum of the 4th power of the signal and an eye diagram of the instantaneous frequency.

DECODER AND DEMODULATOR
ENHANCEMENTS
With this release, there are once again lots of new features for demodulating and decoding. The list of decoders continues to grow, with new decoders like LoRa and DPRK ARQ 600/1200Bd and new features in digital voice communication signals like APCO 25 and DMR

CLASSIFIER Enhancements
Step by step, we use AI-based classification to implement new modulation types or improve existing ones. With this release, we implement classification based on neural networks which greatly improves the probability of intercept for:
- FSK 2
- FSK 4
- FSK 8
- GMSK
- MSK

Classification of FSK 2 modulated signals in disturbed environments
RECEIVER SUPPORT
We follow the wishes of our customers, which is why more and more receivers are supported directly in go2signals products as signal inputs. Your receiver already supports VITA49 - so much the better - then the functional diversity of the go2signals products is directly available to you.
- Added support for IZT R5010 and R5040 receivers
- Added support for CRFS RFeye Node 40-8 receiver

Noteworthy Changes
- Added a mute function in narrowband and task watch channels to silence audio from all other channels.
- Narrowband channels can now be assigned keyboard shortcut focus, with numerous
configurable shortcuts added to support this functionality. - Added support for bulk playback of wideband IQ files, including directory monitoring and automatic playback of new files.
