Firstly: I really hope they find her aircraft. I would love to be on the expedition that finds it. I'm also surprised it took so long to perform (or at least, publicly announce) an RF path/propagation analysis on the distress signals. It is likely that hard information on the received signals was/is low, but it seems crazy that no-one tried. As an ICT/RF Engineer myself, I'd be interested in seeing the raw data they used to triangulate her approximate position. I can't imagine there being a ton of transmitters on the frequencies she could broadcast to in 1937 (the article states 120 possible signals; which is very low compared to today!).
