The antenna receives the emission signal and makes the signal get through the filter that is composed of the L1 and C1, so the 315Hz signal gets the maximum gain. The receiving signal is amplified by the high frequency amplifier which is composed of VT1, so the receiving signal has the larger signal amplitude. The signal of VT1 gets into the super-regenerative detector circuit which is composed of the VT2, L0, C7 and C7, C10.etc to be detected. The output detection signal of the VT2 is amplified by the two-stage amplifier which is composed of the LM358 dual op-amp circuit, then it is sent out to the digital decoder from the output port.
