go2MONITOR, an advanced concept for HF-VHF-UHF data protocol decoding. A smart solution including SDR control, recording, classification and decoding. Manual processing of relevant, intercepted communication is too expensive, too slow, insecure and incomplete. In this situation an automatic, flexible and expandable approach must be used at reasonable size and cost.

At a Glance
The option “Wideband classifier and Input 20 MHz“ extends the signal input bandwidth and the continuous, real time wideband classifier up to 2 MHz on HF or 20 MHz on V/UHF.
It is possible to automatically detect, measure and determine modulation type for all signals in the available frequency range. The results are displayed in the GUI and can be used as an input for further processing
- Wideband input 2.4 MHz (HF) / 20 MHz (VUHF)
- Wideband classification 2.4 MHz (HF) / 20 MHz (VUHF)
- Wideband waterfall display 2.4 MHz (HF) / 20 MHz (VUHF)
- Signal detection in receiver scanning mode
- Continuous classifcation and signal traqcking
- Snapshot Mode
Two operating modes for wideband classification are provided:
This mode can be used with all supported wideband receivers. All frequency ranges required by all active tasks are processed in a round-robin algorithm. The wideband receiver stays on each fixed frequency range for a defined period of time, performs detection, classification and task actions and then proceeds to the next frequency range.
This mode is possible only if the wideband receiver can provide fast panorama scan function (e.g. IZT R3xxx).
First, a wideband scan is performed in the range covering all frequencies required by all active tasks and fast energy detection is performed. The system checks whether any of the detected frequencies with energy fit to any of the active tasks.
If the task contains a trigger based on a complex wideband classification result like modulation type recognition or modem detection and the energy found, the wideband receiver would return after the energy detection to stay longer on that frequency range so that the requested calculation can be performed (typically about 3 s). A classification is only performed in case the energy detection was positive. This prevents the system from spending time on signal-free frequency ranges.
