Phase‐Lock System for the General Radio 1209‐B Oscillator

Design parameter and performance of a simple automatic phase‐control system for a GR 1209‐B triode oscillator are described. The frequency modulation of the oscillator was achieved by varying the B+ voltage of the oscillator tube, so that the resonance circuit does not have to be modified, and the d...

Zusammenfassung:Design parameter and performance of a simple automatic phase‐control system for a GR 1209‐B triode oscillator are described. The frequency modulation of the oscillator was achieved by varying the B+ voltage of the oscillator tube, so that the resonance circuit does not have to be modified, and the described system will change neither the frequency range nor the calibration of the GR 1209‐B oscillator.
