December 2004 QST Feedback

Clarification: As a follow-up to the October Feedback item involving the schematic of "A Simple Well-Behaved Crystal Oscillator" [Technical Correspondence, Sep 2004, p 67], we should also point out that both FET sources connect to resistor R2. Although the text did specify that the oscillator used "...source coupling between stages," some readers were confused because the FET source position was unconventional; it was at the top rather than at the bottom of the FET symbol (when the FET is drawn vertically).
