Uses two different crystals, with frequency being changed by reversing supply voltage，Transistor then inverts itself and gain reduces to about 2, which is adequate for oscillator operation Provides two frequencies from single stage with minimum of switching.-Circuits, 73 Magazine, Feb. 1974, p 101.
