    HP106 Service Manual 2 CIRCUIT DESCRIPTION 2.1 General information The HP-106 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 IQ9 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.

  • Page 6: Synthesizer

    HP106 Service Manual The synthesizer is tuned in 5.00 KHz or 6.25 KHz step. 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.

  • Page 7: Power Control

    HP106 Service Manual 2.4.c Power control Output power is controlled via the dual Op-Amp (Q408) , which is used as a differential amplifier and comparator. Current is sensed by the voltage drop across R421 and R422. This voltage is compared to the one set by the 2- watt Adjustment RV401.

  • Page 8: Receiver Audio Circuit

    HP106 Service Manual The output on IC6 Pin 14 signals the microprocessor IQ9 with a low level (～0V) to unmute the radio. The audio is unmuted by the microprocessor IQ9 Pin 27 switching to a high value (～5V on SQL MUTE) thus biasing on Q206.
  • Page 9 HP106 Service Manual The battery voltage status is monitored by the microprocessor IQ9 Pin 61 which senses the battery voltage through the BATT+SW line by means of IR51/IR49. When the battery voltage is approximately 5.8V, the microprocessor considers the battery discharged and switches off the circuits of the radio.
