Users Manual

operation on GMRS frequencies requires an FCC license, and such operation is subject to additional rules specified in Part 95 including prohibited communications in Section 95.183. For hand held operation, the radio device should be held at least 2.5cm from the user’s face. To maintain compliance with FCC RF exposure requirements, body worn operations are restricted to supply belt clip. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements and should be avoided.

Operational Description

- 1 - CIRCUIT DESCRIPTION 1. RECEIVER SECTION Radio Frequency signal received by the antenna (ANT1), passing through the Low Pass Filter (L1,L3, C2-C5). The RF signal is then amplified by Low Noise Amplifier Q1 and passes through a Band Pass Filter of L6,C511,522,523,C509. The filtered signal within the range of 462MHz is then mixed with the first local oscillator signal from the Voltage Controlled Oscillator (VCO) circuit (Q11,Q10, D7, L18) through Q3, a portion of VCO signal is then feedback to the PLL IC (IC2) for phase comparison generating a stable RX frequency, the output signal is filtered by FL2 (21.7 MHz) which is the first Intermediate Frequency (IF) and is then amplified by Q4. The IF signal is fed to the discriminator IC1 pin 16 which is then mixed with the second local oscillator supplied by crystal X1 (21.25 MHz) to produced a reduced second IF signal which is then filtered by FL1 (KTM450HTW). Demodulated signal is recovered through correct adjustment of IF tank coil (IFT1) and the internal discriminator circuit of IC1. The recovered Audio signal is outputted at pin 9 of IC1 and then processed through filtering done by Q20, the fully recovered audio signal is then further amplified by Power Amplifier IC101. An audible sound is therefore produce by the speaker SPK1 which can be varied digitally from the CPU pins 29,20,31 and the corresponding series of resistors R4,R16,R66. 2. TRANSMITTER SECTION PTT switch (SW1) when pushed triggers the Transmitter Circuit “ON”, the voice signal generates by the surrounding noise passes through the microphone MIC1 where mechanical to electrical transformation occurs, the electrical transformed signal is then filtered by Q18. The output signal is Modulated by a modulator circuit with a varactor diode D7 and L18. The external components from Q10,Q11 form a VCO Circuit which generates the required oscillating frequency for transmission, a portion of this signal is feedback to the PLL IC2 pin 14 for phase comparison in order to produce a stabilized TX frequency. The modulated signal is then amplified by a Cascaded Amplifier Circuit Q7 and Q8 and again amplified by Q2,Q5 ,Q6 to produce a sufficient Radio Frequency signal emitted by the Antenna (ANT1). 3. CALL TRANSMISSION By pushing the PTT/CALL key, a signal is detected by the CPU (IC105), a CALL data is then produced by the CPU. This data passes through the Low Pass Filter Q18 and modulated by the varactor diode D7 and L18. The signal follows it’s conventional transmission section path through the antenna. - 2 - 4. BATTERY LOW DETECTION Battery Low Detection is controlled by the CPU pin 20 as detected on the LCD 1, however a voltage divider circuit R57 and R64 serve as the stabilize reference voltage for the CPU to process its detection. 5. SQUELCH DETECTION Supported by the linear IC circuit (IC1), a resistor R21 sets the level of detection and Diode D3 acts as a comparator circuit interface with the CPU. 6. POWER SUPPLY Supply voltage of 6 Volts dc is needed to power “ON” the whole circuitry, by four (4) batteries “AAA” size.
