He had the trifecta:
1) sidebars around his main signal
2) second and third harmonic of his audio frequency
visible on the waterfall (600, 1200 & 1800 Hz)
3) drifting just enough during and between transmissions
for fldigi to lose track trying to copy his signal
The only thing missing were background noises from his
