Phase-Conjugate Transmitter Calibration
How much the pulse affects volume (0% = constant, 100% = full pulsing)
Quietest point of pulse (0% = silent troughs, 100% = no pulsing)
1. Connect piezo device via USB
2. Strike 128 Hz tuning fork and hold near piezo
3. Adjust carrier frequency until you hear/feel zero beating (no wavering)
4. Your biometric target is 127.60 Hz — the 0.4 Hz offset from 128 is intentional
5. The pulse rate (7.9753 Hz) is your breath rate — adjust to match your natural rhythm
Assembly: Piezo (copper side) → Quartz Crystal → Mastoid Bone (behind ear)
