Midland Radio Corporation subscribes to the same safety standard for the use of its products. Proper operation of this radio will result in user exposure far below the Occupational Safety and Health Act (OSHA) and FCC limits. DO NOT transmit for more than 50% of total use time (50% duty cycle). Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. • This radio is NOT approved for use by the general population in an uncontrolled environment. This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control the user’s exposure conditions for satisfying the higher exposure limit allowed for occupational use. • When transmitting, hold the radio in a vertical position with its microphone 2 inches (5cm) away from your mouth. • The radio is transmitting when the red LED on the front of the radio is illuminated. You can cause the radio to transmit by pressing the PTT bar on the radio. • When using VOX mode the radios transmitter is automatically activated with your voice by speaking into the microphone. Use caution when using VOX mode. • These are required operating configurations for meeting FCC RF exposure compliance. Falure to observe these restrictions means violation. This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference. 80-106/80-406 User manual Page. 3 In this book...

Page 2 of 41 2 CIRCUIT DESCRIPTION 2.1 General information The 80-406 has three printed circuit boards. Circuitry is divided in the following sections: • Microprocessor/Control • VCO/Synthesizer • Transmitter • Receiver • Signalling • Battery Refer to the Block Diagram and the Schematics. 2.2 Microprocessor/control The microprocessor Q17 is constantly operating when the radio is turned ON. It is continuously monitoring the keyboard, the PTT line and other internal inputs such as the squelch detect, etc. When a change occurs, the microprocessor makes the appropriate response. The microprocessor is used for control. The Radio emits a beep on channel change and the synthesizer is loaded with the correct frequency information. The microprocessor runs off a 8 MHz oscillator which is composed of X1, C30, C31 and R48. When the radio is first turned on, the microprocessor reads the radio status from the EEPROM Q8. The microprocessor determines the receive frequency codes, then loads the synthesizer via its pins 42 (PLL LE), 46 (PLL CLK) and 43 (PLL DATA). The microprocessor is fitted with an internal program flash memory as well, therefore functions can be customised, if necessary, upon specific request from the customer (fees may apply). 2.3 VCO / Synthesizer (PLL) This section consists of the Temperature-Compensated Crystal Oscillator (TCXO), Voltage Controlled Oscillator(VCO), Synthesizer and the Loop Filter. 2.3.a Temperature-Compensated Crystal Oscillator (TCXO) The reference oscillator (X401) is a temperature compensated crystal- oscillator, RV402 is used to adjust the oscillator on frequency (14.4 MHz) at room temperature (22 Ž). The reference oscillator is held within the specified ±2.5 PPM from -30 to +60°C. 2.3.b Voltage-Controlled Oscillators Only one of the VCOs runs at a time, which is controlled by Q420 and Q17. When the PTT is pressed, Q17 pin 34 goes low (approx. 0V) disabling the receive VCO by the Q420 and biases on Q419 to enable the transmitter VCO. The receive VCO consists of C989-C994, CV901, L926-L428, L933, and Q922-Q923. This VCO oscillates at 45.1 MHz below the programmed receive frequency. The VCO’s oscillating frequency is tuned by the varactor Q923. The tuning voltage is supplied from the output of the Loop Filter. The output of the VCO is AC coupled to the output buffer Q914. The buffered output is coupled to the synthesizer by R558, C530, and C505. The transmitter VCO consists of C980-C985, C987, CV901, L924, L925, L929 and Q916, Q917. This VCO oscillates on the programmed transmit frequency. The VCO’s oscillating frequency is tuned by the varactor Q417. The tuning voltage is supplied from the output of the Loop Filter. The output of the VCO is AC coupled (C979) to the output buffer Q915. The transmit voltage controlled oscillator is directly frequency-modulated and operates on the carrier frequency. In the receive mode, the transmit VCO is disabled and the receive VCO is enabled, producing the receive local oscillator signal at a frequency 45.1 MHz below the incoming receive frequency. The synthesizer is tuned in 5.00 KHz or 6.25 KHz step. 80-106 Service Manual Page 3 of 41 2.3.c Synthesizer The frequency synthesizer is a large scale monolithic synthesizer integrated circuit Q429. The synthesizer IC contains a dual modular prescaler, programmable divide-by-N counter, prescaler control (swallow) counter, reference oscillator, reference divider, phase detector, charge pump and lock detector. Also, included in Q429 are shift registers and control circuits for frequency controls and general device control. RF output from the active VCO is AC coupled to the synthesizer Q429 prescaler input at Pin 8. The divide-by-N counter chain in Q429, consisting of the dual-modulus prescaler, swallow counter and programmable counter, divides the VCO signal down to a frequency very close to 5.00 KHz or 6.25 KHz which is applied to the phase detector. The phase comparator compares the edges of this of this signal with that of the 5.00 KHz or 6.25 KHz reference signal from the reference divider and drives the external charge pump (Q425 and Q426). The synthesizer unlock detector circuit prevents the operation of the transmitter, when the phase lock loop (PLL) is unlocked. The following discussion assumes the unit has been placed in the transmit mode. Q429 lock detector Pin 7 goes high when the PLL is locked. This high level is applied to Pin 21 of the microprocessor Q17. A software timing routing brings the RX/TX line low (Pin 29 of Q17), feeding this signal through the switch/buffer Q15. With the RX/TX line low, Q223A is cut off and Q223B is biases on passing +5VTX to Q431B, it biases on Q430 to pass switched TX B+ to the transmitter amplifier string which enables transmission. When the PLL become unlocked, the lock detector at Q429 Pin7 will begin pulsing low. A RC circuit converts pulsing low to a low level for the microprocessor. The microprocessor then changes the RX/TX line to a high, thus signalling the other transistor switches to drive Q430 into cutoff which disable transmission. Therefore, the transmitter remains disabled while the loop remains out of lock. 2.3.d Loop Filter The Loop Filter, a passive lead-lag filter consisting of R461-R464 and C493-C495, integrates the charge pump output to produce the DC turning voltage for the VCO. One parasitic pole, consisting of R461/C493 and RF chokes L428/L429, prevent modulation of the VCOs by the 5.00 KHz or 6.25 KHz reference energy remaining at the output of the loop filter. Direct FM is obtained for modulating frequencies outside the PLL bandwidth by applying the CTCSS/DCS signals and the pre-emphasized, limited microphone audio to the VCO modulation circuit. The modulation circuit consists of R452, Q421 and C487. 2.4 Transmitter 2.4.a RF Power Amplifier After the PTT is pressed, the +5VTX line switches to approximately 5V. Q919 is turned on enabling transmit VCO. The VCO buffer, pre-driver, driver and power amplifier are biased …
