IIRC, quite some years ago, QST had a photo & description of a FCC "signal locator" (for lack of a better description) consisting of several remote receivers that were linked together.
Anyway, these could instantly locate the origin of a skywave signal with a resolution of a city block(!!) using a precise timing equipment/technique. I looked for the article using the ARRL's periodical search...no luck. Does anyone remember reading/seeing that article...perhaps in the "Strays" column of QST?
