Field notes
The app asks users to choose a listening interest, such as aircraft or amateur radio, and says it handles band plans, channel widths, and modes. Its page also describes per-receiver gain and PPM settings, custom ranges and exclusions, and spectrum and waterfall views. Several receiver integrations are explicitly still awaiting hardware checks.
