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?
