Speedboats and RDF
A random thought about the Persian speedboat cat-n-mouse game. Surely our Navy ships have directional antennas on their receivers? They did in WW2. With directional antennas on two ships, you can locate a transmission quite accurately. And if the transmission is coming from a speedboat zipping back and forth, you should be able to distinguish such an extreme side-to-side movement even without triangulation.
Thus the Navy's seeming uncertainty about the source of the Darth Vader voice is puzzling. Has George W. Gandhi ordered the Navy to abandon radio direction finding because it gave us an unfair advantage? Or is the whole thing a fraud?
