I don't agree at all. 73 had more homebrew articles. However, QST's projects were selected for suitability; constructed and tested in ARRL's laboratory; and carefully edited. 73's projects were none of the above.
Exactly! I forget the details, but I recall one project published that was actually dangerous to build. It was sent in in the 1970's as a gag (or test) of sorts. And amazingly, 73
actually printed it.
Ask W8JI about it. I remember him talking about it on the 147.375 repeater in Toledo, OH many years ago. IIRC, he actually called Wayne Green about this, and Wayne's defense was "Why would anybody [who sends in technical articles to be published] want to lie to us?". Amazing.
Look at the page of editors' names, etc. in some 73 magazines of that era. The lack of a technical editor was glaringly obvious.
QST was better back then, yes. But no ham magazine published in the USA were better than Ham Radio
before Jim Fisk, W1HR, died.
