QST Recognized Error on Sideband Inversion, But Continued to Make the Same Mistake


I don't really know if this is good news or bad news.  It's good that in November 1985 they recognized the error, but then they allowed the same error to be repeated by the same author in the 1989 article "A Four-Stage 75-Meter SSB Superhet," and again in 1990 in W1FB's Design Notebook.   It also made it into the 2002 ARRL Handbook.  

Thanks to Chuck WB9KZY for alerting us to this Feedback piece.
