I mentioned the possibility of convergence zone detections but at such high frequencies, if it does occur, I would be surprised if it extended beyond the first zone and barely conceivable to reach the second. Assuming 30 mile spacing that would limit the range to 120 miles.
Now if the two detections could be time synched and identified as the same source you could construct a hyperbolic line and match this with the ping arc . . .
argh!
