I would suppose you would have to plot the azimuth from two different array sites (separated by hundreds or, preferably, thousands of miles) and triangulate. Can't think of any way to do it from a single point on the earth. You could approximate it by having some knowledge of how long the HF skip distance appears to be over the path in question at the time the signal is heard, but that sure wouldn't pinpoint it for you. Might put you in the right (large-ish) country... Bill W5WVO > > I did think PA0SIM's phase coherent K2's was kind of cool.
