Long analysis of Earhart’s radio signals:

I read it all. Not sure I understood it tho.
I recall reading some book about the screw-up with the time zones. Earhart was to use radio on the hour and half-hour, and telegraph(?) (morse code) on the quarters. Well the power was out on the island and messed things up. And the time zones were messed up as the ships in the harbor were still on the time zones for their port of origin. Something in there as well about the switch to go from radio to telegraph was installed backwards, and earlier trips Noonan had been on the wrong frequency. IIRC, Noonan was fairly new as her navigator.
I don’t recall it exactly - but pretty messed up. The screw up led to establishing Greenwich Mean Time so planes and ships would all be on the same time.
I have not heard of this theory either. The physical evidence of the tag seems pretty compelling, although the distances seem quite far. I can just imagine the conversation in the cockpit, the reasoning, the calculations, the odds, the risks.
Head to the Marshal Islands? Well then we have the Japs to deal with. Keep doing a grid search for Howell? Head back?
