4 OPERATION INSTRUCTIONS Having properly installed your batteries and hooked-up the antenna, you are now ready to operate your radio for optimum reception and voice transmission. Turn the power ON with ON/OFF switch. Set the desired channel. Adjust the squelch control knob to reduce any undesirable background noise when no signal is being received. To do this, select a channel where no signal are present, or wait until signals cease on your channel. Then, rotate the squelch control knob clockwise to a point where the background noise disappears. Note: When the squelch is set properly, the speaker will remain quiet until a signal is received. In order to receive weak signals, do not set the squelch too high. Adjust the volume to the desired listening level. To Transmit Press and hold the push-to-talk button. Speak slowly and clearly in a normal voice two to three inches from the microphone. A buit-in modulation control circuit will automatically adjust the microphone input level. There is no need to speak loudly. To Receive Release the push-to-talk button. For Stage: Release Date: Page: 4 Of 57
5 THEORY OF OPERATIONS TRANSMITTER A. RF Amplification The output of double AMP Q201 is fed through tuning T203 and T204 to the base of pre driver AMP Q202. The output is then supplied to RF driver AMP Q203. The output of Q203 is supplied with tuning circuit L204 and C214, C215, C216 and goes to the base of final RF AMP Q204. The output of Q204 is supplied to the antenna through L-C tuning circuit. B. Circuit for Suppression of Spurious Radiation The tuning circuit between the output of final AMP Q204 and antenna, 5-stage PHI network C221, C219, C220, L206, C223, C245, L207, C241, C228, C240, L208, C242, C230, C229, L209, C234, C233, C232, L210, C243, C235, C236 serves as a spurious radiation suppressor. This network also serves to match the impedance between TX power AMP Q204 and the antenna. C. Circuit for Limiting Power After finished all alignment, the constant voltage supply circuit limits the available power 4 W or slightly less. RV501 and corresponding three transistors Q509, Q502, Q501 control supply voltage of RF amplifier and other circuits. Tune all the trimmer parts for maximum indication of RF power meter and adjust RV501 to make 4 w indication of RF power meter. The tuning is adjusted so that the actual power is from 3.8 to 4.0 W. There are no other additional controls for adjusting the TX output power. D. Modulation Control a. FM The mic input is fed to audio amplifier IC KIA324 which drives modulation varicap diode D302 in the VCO circuit. RV701 limits the incoming modulation audio levels to inhibit over modulation. While reading the modulation factor on the modulation analyzing equipment, adjust RV701 shall not exceed +/-1.6 KHz/Dev. After 20 db up from 1.25 KHz/1.2 KHz/Dev. Audio level b. AM For Stage: Release Date: Page: 5 Of 57
6 Modulation signal is fed to audio amplifier IC KIA324 and goes to TX voltage regulate circuit Q509, Q502, Q501 to make nominal signal level to achieve wanted modulation. To control incoming audio signal, R272 and corresponding ALC circuit limits the modulation shall not exceed +/-60% adjust RV702 +/-60% modulation under 1.0 KHz AF 60% mod plus 20 db of audio signal. E. Receiver CB receiver is dual conversion supper-heterodyne type with the first IF MHz and second IF 455 KHz. Receiver is separated two blocks, 1 st IF section and 2 nd IF section. The PLL synthesizer supplies first local frequency ~ MHz.(for EU) and MHz ~ MHz (for UK) With the provided first local frequencies Q102,Q103 mixes the incoming RF signal to generate first IF signal. Mixed signals were filtered with the CF101 ( MHz) crystal filter and other tuning circuits. Output signal of mixer is filtered with CF102 (455 KHz ceramic filter). The 455 KHz signal from the 2 nd IF filter was amplified and limits internally. After amplification the signals fed the quadrature detector loop T104. Then we can see the recovered audio signals on Pin 12 for FM and Pin 13 for AM of IC1. For Stage: Release Date: Page: 6 Of 57

16 PLL CIRCUIT BLOCK DIAGRAM 1. INTRODUCTION The frequencies for transmitter and receiver first local frequencies are all derived from a single MHz crystal by means of a phase locked loop. The first local oscillator frequencies are MHz (CH 1) to MHz (CH 40) for EU and MHz (CH 1) to MHz (CH 40) for UK. The second local frequency is fixed at MHz to generate second IF 455 KHz. During transmit, The VCO of the PLL operates MHz (CH 1) to MHz (CH 40) for EU, MHz (CH 1) to MHz (CH 40) for UK the VCO frequency goes to the double circuit Q201, T203, T204 which doubles the frequency to generate MHz (CH 1) to MHz (CH 40) for EU and MHz (CH 1) to MHz (CH 40) for UK Q 201 VCO T203,T204 Doubler To Transmitter MHz (CH 1) EU MHz (CH 1) MHz (CH 40) EU MHz (CH 40) MHz (CH 1) UK MHz (CH 1) MHz (CH 40) UK MHz (CH 40) The VCO operating frequency for the receiver is , MHz (CH 1) to , MHz (CH 40) as the first local oscillator, injected through the buffer AMP Q302 into the first fed balanced mixer Q102, Q103. For Stage: Release Date: Page: 16 Of 57
17 2. BASIC SYNTHESIZER SCHEME The crystal frequency (10.240MHz) is divided by 1800 times to make 2.5 KHz which is fed to one side of the phase detector. The VCO output is divided by a programmable divider, and fed to other side of the phase detector Pin 11 of IC302. The feedback loop is closed by passing the phase detector output through an active low pass filter and using the output to control the VCO frequency through varicap diode D301. Under locked conditions, both of phase detector input signal must be indential at 2.5 KHz. The VCO frequency is then given by: FVCO / N = MHz or FVCO = x N MHz Since N is an integer, the VCO frequency can be stepped up with 2.5 KHz increments. By suitable choice of N the desired output frequency can be obtained.

18 The VCO frequency goes to the double circuit, which doubles the incoming signals. Transmit Transmit CH 1, MHz CH 1, MHz CH 40, MHz CH 40, MHz Double output Frequency MHz MHz MHz MHz Since all frequencies are obtained from the crystal controlled PLL oscillator, all outputs are coherent with the crystal oscillator frequency and maintaining the same percentage accuracy.

21 3. DESCRIPTIONS OF EACH BLOCK A. Introduction The synthesizer is implemented with the following Components: - PLL IC (IC302) - X-TAL (X302) - VCO, VARICAP DOIDE (D301) IC302 is a cmos LSI that includes most of PLL block and driver, the Q301, C305, C306, C304, C301 and T302, Varicap diode D301 are clapp oscillator circuit to operate as a VCO of the IC302. Q301 is a switching transistor to connect or disconnect the tuning capacitor in the VCO oscillator tank circuit for transmitter or receiver. Q304 works as a buffer AMP for RX local frequencies (16 MHz) and TX generating frequencies (13 MHz). B. Reference frequency The crystal, X302 (4.50 MHz) and other components of IC302 can make a reference frequency oscillator with internal amplifier. C. VCO Q301 and surrounding parts are consisting a clapp oscillator works as a VCO of IC302. the VCO can be oscillate over the required of MHz to MHz D. Phase detector and VCO control The detector is a digital phase comparator which compares the phase of the reference signal with programmable divider output square waves and develops a series of pulses whose DC level depends on the phase error of each signal. E. Transmitter/Receiver buffer AMP Output signal of Q301 is fed into buffer AMP Q302, F. Transmitter doubler The output signals of Q302 goes to an amplifier with tuning circuit Q201, T203, T204 which doubles incoming 13 MHz signals. G. Switching of tuning capacitor in VCO The VCO circuit must tune with a wide rang of frequencies ~ MHz (EU), ~ MHz (UK) for transmitter and ~ MHz (EU), ~ MHz (UK) for receiver. To comply above range of VCO, the tuning capacitance should switched for transmission or reception. For Stage: Release Date: Page: 21 Of 57
22 H. Receiver local oscillator outputs First Mixer: The secondary output signals is injected to the sources of 1 st mixer Q102, Q103 in the 1 st IF mixer section Second Mixer: The output of MHz oscillator circuit with X101 is injected into the IF IC internally. Incoming IF signal and MHz are mixed inside the IF IC to extract 2 nd IF signal 455 KHz. FM,AM audio signals are recovered with the way of quadrature detector, AM signals are recovered with envelope detector. 4. FREQUENCY STABILITY LET: Fo = Crystal oscillator frequency Fr = Phase detector reference frequency Fvco = VCO frequency Ft = Transmit frequency Then: Fr = Fo/1800 And under locked conditions: Fr = Fvco / N THEN: Fvco = N X Fr WHERE, N is the programmable divider divide ratio. From which it can be seen, the percentage error in Ft is the same as the percentage error in Fo. The stability of the crystal oscillator is determined primarily by the crystal itself and having lesser deviation by the active and passive components of the oscillator. The choice of crystal and component is such that the required frequency stability is maintained over the required voltage and temperature rang. For Stage: Release Date: Page: 22 Of 57
