Abstract
A highly versatile Digital Analysis System (DAS) for spectrum monitoring applications has been developed by the Communications Research Centre of Industry Canada. The system is made from commercially available VXI-based hardware and can be used in both fixed and mobile spectrum monitoring stations. The software control of the equipment, coupled with the use of personal computer for digital signal processing, allows the DAS to be easily reconfigured to address the specific requirements imposed by the modern wideband and narrowband digital systems as well of those of nondigital transmissions. The DAS software measures technical parameters such as power, carrier frequency, S/N ratio, channel and band noise level, modulation type, modulation level, baud rate, signal bandwidth and performs high speed channel occupancy (>20,000 channels/s). The DAS also provides "instantaneous" Line Of Bearing (LOB) for transmitters in a 4.5 MHz band using the Butler matrix technique.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
