FCC caution: Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. FCC 15.21 Modifications not authorized by the manufacturer may void users authority to operate this device. FCC 15.19 This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Circuit Description I.Transmission section. 1. Audio frequency amplifying section. MIC signal input @pin9 of U8, through amplification and compressor of U8 , The output signal @pin16 goes to FM modulation. 2. VCO section. Q301, Q302 work as VCO, the varactor D302 value i3 controlled by PLL Part of U8 . 3. Power amplifying section. Q11 is a buffer, Q4 is a driver transister,Q1,Q2,Q3 work together as power amplifier. When the signal has been amplified , it will be passed to a switch diode D2 and send out from antenna. II.Receiving section. 1. RF section. The signal received by antenna passed to filter network, then amplified by Q6, via band-pass filter network, then goes into mixer Q8. 2. Local oscillator and Mixer. Q7 is frequency mixing transistor, the VCO act as local oscillator , the frequency is controlled by PLL, after mixing, the IF(21.4MHZ) signal selected by CF1, then output via L12 and C54 to U8. 3. IF section. CF1 is 21.4MHz crystal filter, second IF is 450KHz, U8 works as second mixing, second local-oscillator, second IF amplifier, demodulation etc. 4. Audio section: The demodulated audio signal goes to U4 and is amplified, and then U8 drives Speaker. III.Others. The PLL circuit is embedded in U8, X202 is a local oscillation crystal, CT201 is a trimmer, the U8 pin 46 output constant current to control D302 oscillation frequency.
