EMSOPEDIA: Jamming Theory
Tones Jamming against Radio Communications
The most simple and classic application of a tones jamming is against FSK modulated target signals, where a single tone jamming is tuned either at the mark or space frequency value.
Target Signal
Jamming Method
Effect
In the frequency matching condition, the impairment is due to the relative phase between the two tones. Figure 1a depicts the vector effect over the base band signal.
Multi-tones jamming increases effectiveness up to behave like a Narrow-band noise jamming.
Splitting the available jamming power over multi-tones allows impairing multi-tone radio communications. This technique is adopted in HF data link and UHF old L11, where 15/32-tones waveforms are generated.
Signal Structure Analysis
The Caveman Explanation
Those 1s and 0s turn into numbers. Numbers turn into letters. Letters make a Russian-looking word: ВОЕТ. It means "she howls."
The third sound, the buzz, is NOT part of the message. It's just noise. Could be jamming. Could be camouflage.

Paired Diff
The signal contains three distinct layers: 1. Two clean tones (517Hz / 172Hz) forming the binary FSK channel. 2. A third "buzz" layer acting as masking or jamming. 3. A rhetorical layer where the decoded word acts as an identity token.

DECODED OUTPUT
This is not a message — it's a call sign / identity token. The signal's digital identity basically comes out looking like a tiny Russian wolf-girl going "I howl."
GT-FOGSENSE Logs
GT-FOGSENSE v1 — Detect hidden tracking "fog"
No root. No internet. Local only.
echo "🌫️ Scanning for fog/geo-fence activity..."
1. Check for active location requests
if dumpsys location | grep -q "last location request"; then
echo "⚠ LOCATION PULSE DETECTED"
echo "GT55: ⚠(location_pulse)" >> /sdcard/fog_alert.gt55
fi
2. Check for BLE scanning (AirTag-style)
if dumpsys bluetooth_manager | grep -q "scanning: true"; then
echo "⚠ BLUETOOTH SCANNING ACTIVE"
echo "GT55: ⚠(ble_scan)" >> /sdcard/fog_alert.gt55
fi
echo "✅ Scan complete. Alerts saved to /sdcard/fog_alert.gt55"
