IRCUITS MAIN UNIT The 1st mixer circuit converts the received signal to a fixed frequency of the 1st IF signal with a 1st LO VCO output fre quency By changing the 1st LO frequency only the desired frequency will be passed through two crystal filters at the next stage of the mixer e 2ND IF AND DEMODULATOR CIRCUITS Squelch level adjustment pot R16 C26 AF signal DET C25 The signals from the RF circuit are mixed with the VCO sig nals at the 1st mixer circuit Q1 to produce a 21 7 MHz ist IF signal The ist IF signal is applied to two crystal filters F12 to suppress out of band signals and is then amplified at the IF amplifier Q2 The amplified signal is applied to the 2nd mixer circuit IC1 4 1 4 2ND IF AND DEMODULATOR CIRCUITS MAIN UNIT The 2nd mixer circuit converts the 1st IF signal to a 2nd IF signal A double superheterodyne system which converts receive signals twice improves the image rejection ratio and obtains stable receiver gain The FM IF IC IC1 contains the 2nd local oscillator 2nd mixer limiter amplifier quadrature detector and noise detector circuits etc The 1st IF signal from Q2 is applied to the 2nd mixer section of IC1 pin 16 and is mixed with a 21 25 MHz 2nd LO sig nal generated at the PLL circuit using the reference fre quencv 21 25 MHz to produce a 450 kHz 2nd IF signal The 2nd IF signal from IC1 pin 3 is passed through the ceramic filter FI3 wher
