The lock-in condition of the phase-detector reactance tube-controlled oscillator afc system has been investigated. For the case of RC coupling between phase detector and the reactance tube, an explicit relation is obtained for the lock-in condition which involves the filter time constant, the initial frequency error, the phase detector constant and the reactance tube controlled oscillator sensitivity constant.
