Connected to a shortwave receiver, this circuit is intended to enable the decoding of signals in SSB (Single Side Band). Adjusts the small IF transformer used as oscillator for best performance. The circuit is powered by a 9 V battery and the transistor may be the BC558. The circuit is from an old Argentine publication of the 70's. (Obs: connect a 100R resistor between the emitter and earth, if the circuit does not oscillate)
