Wow! It certainly looks like SSB communications from Niku to the mainland is quite successful, at least listening late at the night. But most of the credible post-lost signals heard in the States were heard during daylight hours (e.g. Betty, listening after school). And of course, on AM, not SSB.
If this portion of the project is intended to test the harmonic theory, will the group attempt AM communication to the mainland, during daylight hours (in the States)? And, perhaps, at somewhat reduced power to mimic the harmonic generation of Earhart's transmitter and antenna?
