(under subclass 14) Subject matter in which the variable reactance tuner is provided with control means for automatically tuning the resonant circuit to its optimum operating point and to maintain the circuit at that point by regulating the adjustment of the variable reactance tuner to compensate for variations in the tuned circuit or in the frequency of the signal wave to which the circuit is tuned.
