Flags

Only signatures that look hotter than ambient, saturate the stick, sit on an ISM heating frequency, or match a published directed-energy watch band. Broadcast FM is not a weapon.

Why flagged

  • Well above typical ambient for this allocation.

Human health at harmful levels

At harmful levels: deep tissue heating (centimetres), core-temp rise, cataract risk only at extreme chronic occupational microwave. A leaking industrial heater is the realistic local threat. Public whole-body reference at this frequency is 4.57 W/m² (f/200, ICNIRP 2020).

Directed-energy relevance

915 MHz ISM and 800–900 MHz are inside published high-power-microwave research ranges. Saturated, persistent, or pulsed energy here is a primary watch condition for this app.

Power density is an uncalibrated 0 dBi estimate from received power. A USB stick is not an ICNIRP field probe. Saturation means “too strong to measure,” not “weapon confirmed.”
