Product Title :	Frequency conversion circuit
Pattern
Feature
End Use
Product Description	Frequency conversion circuit, oscillation and mixing together referred to as the inverter circuit. Frequency conversion tx1 circuit based on VTl as the center, its role is to through the different radio frequency signal input circuit receives (high frequency signal) to transform the fixed intermediate frequency signal of rxb9 465 KHZ. VTl, T2, CB and other components of the local oscillation circuit, its task is to produce a constant amplitude is higher than the input signal frequency, 465 KHz high frequency tx1 oscillation signals. Due to Cl quite short circuit with high rxb9 frequency signal, Tl and inductance of the secondary Lcd is small, provided the pathway of the high frequency signal, so the local oscillation circuit is common base circuit, oscillation frequency controlled by T2, cB, cB is double the other in a row of the capacitor, adjust it to change the local tx1 oscillation frequency. T2 is oscillation coil, the first round on the same core, they are magnified the VT1 electrode, such as the output of the coupling oscillation signal in the form of positive feedback to the oscillator circuit, rxb9 voltage from the T2 primary tap local oscillation, derivation by C2 coupled to VT1 emitter.

Product Title :	The AGC control voltage by R3 to VT2 is the base
Pattern
Feature
End Use
Product Description	The AGC control voltage by R3 to VT2 is the base, the control process is: Outside rxb11 signal voltage and write Vb3 write - Ib3 - the Ic3 write - vc33 left, by R3, Vb2 left - > Ib2 left - > Ic2 left left - > tx3 signal voltage. The detection level is the main task of the intermediate frequency modulation rxb11 signal back into audio signal, C4, C5 filter to the remnants of the role of intermediate frequency components. Lead low circuit, detection of audio signal after filtering by potentiometer RP to lead low pipes VT4, through low voltage amplification dozens to hundreds, tx3 audio signal but audio signal after amplification on load ability is very poor, rxb11 also can not directly promote the speaker work, power amplifier is also required. Rotating potentiometer RP can change VT4 base on the size of tx3 signal voltage, can achieve the purpose of the control volume.

Product Title :	Input circuit is composed of double variable rxb3 capacitor of CA
Pattern
Feature
End Use
Product Description	Input circuit is composed of double variable rxb3 capacitor of CA and T1 Lab primary coil, a parallel resonant circuit, Tl is magnetic antenna of rxb15, from the antenna in the high frequency signal, through the input circuit resonance choose need radio signal, radio frequency signal is f = l / 2 PI LabCA, when change the CA, will be able to receive radio signals of different frequency. Power rxb3 amplifier (OTL circuit), the task of the power amplifier is not only the output voltage, and can output the larger current. This circuit USES no power amplifier output rxb15 transformer, can eliminate the distortion of the output transformer caused and loss, good frequency characteristic, can also reduce the volume and weight of the amplifier. VT5, VT6 push-pull circuit, of the same type transistor R7 and R8, and R9, R10 VT5, VT6 deviator resistance. Do inverter coupling transformer T5, C9 is blocking capacitance and coupling capacitance. In order to reduce the rxb3 frequency distortion, the better the greater the capacitance C9 selected. No output transformer of power amplifier's output impedance rxb15 is low, can drive a speaker work directly.
