Scan, investigate, and share with your team.
Across your ATAK network.
The investigation workflow
A spectrum trace and waterfall show received activity over time. Sweep a range, then focus on the frequencies that need a closer look.
The recorded workflow shows the model selecting signals for investigation and making five-second I/Q captures for closer analysis.
Review captures and automatically catalog frequency observations. Revisit the evidence as your understanding of the RF environment develops.
Spectrum
See received activity across the spectrum, then focus your investigation. The local model can select candidates for a closer look.
Waterfall
Frequency runs across the display. Each new row adds received activity to the history below it. This screenshot shows a 1.024 MHz window centered at 424.786 MHz, captured with the USB HackRF.
I/Q captures
The recorded workflow makes five-second I/Q captures for analysis. Review saved captures and retain the evidence behind each investigation.
Signal catalog
Keep observations organized by frequency and review the supporting captures. A catalog entry records activity; it does not establish a unique transmitter identity.
The recorded analysis returns Unknown / inconclusive and recommends narrowing the capture. That result stays visible, alongside the measurements that informed it.
05 / Team
RF investigation is a team capability. Share what you find across the ATAK network and visualize your teammates’ SDR activity on your own screen.
Share findings with teammates across your ATAK network so the signals you investigate become part of the team’s shared picture.
Visualize a teammate’s SDR on your screen. See what their receiver is observing alongside your own investigation, wherever you are working on the ATAK network.
Receiver support
SPECTRUM supports HackRF and RTL-SDR. Frequency coverage and reception capabilities depend on the connected hardware.
A real sweep, model-selected candidates, five-second I/Q recordings, a waterfall, tentative analysis, and an automatic frequency catalog. The eight-second hero is a motion-graphics preview using real app footage; the screenshots below show individual views.
This recording does not establish confirmed protocol or transmitter identification. It does not demonstrate transmitter geolocation or map-marker tagging. Frequency buckets are observations, not unique transmitter identities.
