Why Planes Vanish: The Mystery of Flight MH370

WSPR is a ham-radio weak-signal network. Godfrey argues an airframe crossing a WSPR transmitter–receiver path disturbs the recorded SNR in a way that can be stacked into a track. He has published successive end-points (including 33.17°S 95.3°E, then 30.57°S 98.75°E, then a circle of radius 30 km centred near 29.128°S 99.934°E, about 2,827 km²). Royal Institute of Navigation commentary in 2026 noted the articles are not in accredited journals and the underlying database is not independently auditable. Ocean Infinity’s 2025–26 boxes were not a dedicated WSPR-circle search; Godfrey states no AUV launch has covered that circle. File WSPR as an unverified extra trace that has moved, not as a replacement for Inmarsat.
