No, sah....it's Sub-Audible Heterodyne, the pulsating heterodyne
between stations, that is, well, sub-audible, being below, often well
below, the recognized lowest frequency humans can hear . As to its
origins as an abbreviation, that I couldn't say, though I remember it
being used in the medium wave clubs in the seventies, when precision
frequency measurement (PFM, another acronym of limited scope?) was
being investigated by such as this list's own C. Taylor. Possibly
"SAH" originated there, and never moved very far beyond? Don't
believe I've seen it used elsewhere.
And...the magazine, Dan...EDN? (another acronym...) Honored to meet
you in any case, but especially if you are the Mr. S. from that publication.
best wishes,
Nick
