I would caution anyone against using this demonstration as definitive proof of anything. There are too many variables in the mix for TIGHAR to make any claims that this bolsters, or detracts, from the Nikumaroro hypothesis.

Well, that was actually kind of where I was heading....
Although my brother is a ham, I myself actually know precious little about it. (Other than a brief dalliance over 40 years ago when CB went berserk. And comparing those is apples and oranges.) However, I DO know that the propagation properties of a signal at 3105kc and one at 20-meter SSB are hugely different.
As such, I'm afraid we're not really proving very much, are we? (...sad as it is to say that.)
However, my brother and I have been tuning in these past few days and the whole thing is really quite a gas. (...still don't understand what any real difference there is between contacting someone on an island and someone on a boat moored offshore of that island. After tens of thousands of miles....is the last 700 meters really that big a deal?)
