An interesting theory, but I suspect that it's incorrect as far as the actual origin of the word is concerned. When Armstrong invented the superheterodyne technique, the most "refined" receiver type available was called the "super-regenerative" (which, I assure you, had nothing to do with regenerating supersonic frequencies - although the "regeneration" *did* take place in the RF stages). I suspect that he simply picked up the "super" prefix from this as a Good Marketing Move. Bob Myers KC0EW HP Graphics Tech. Div.| Opinions expressed here are not Ft.
