Low-drift solid-state design for 40-meter band has maximum change of only 25 Hz from cold start to full warm-up at 25?. After stabilization, maximum hunting is 5 Hz. Drift is minimized by paralleling two or more capacitors in critical parts of circuit. Series-tuned Colpitts oscillator is followed by two buffer stages, with second providing enough amplificati..
