The "100-miles out" comment is suspected to have been an estimate by the radio Operator, not something said by AE.  See Note 3 at http://tighar.org/wiki/Transmissions_heard_from_NR16020 If so, then it can't be used for our navigation analysis, other than to assume AE was at her closest approach to the island.

Also, in discussions about loop antennae, keep in mind that they have frequency limits.  AE seemed to have a fuzzy understanding of how to use the antenna to obtain a minimum, but specified a frequency that would not work with that antenna.

dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah dit dah

   10     20     30    40    50    60    70    80    90   100   110   120   130   140   150   160   170   180   190   200   210   220   230   240

Can you find the minimum?  Neither could she.  Her loop antenna was only sensitive to different directions much lower frequencies.
Cheers,
