    1.2.1 FLASHport® The ASTRO Digital Spectra and Digital Spectra Plus radios utilize Motorola’s revolutionary FLASHport technology. FLASHport makes it possible to add software that drives the radio’s capabilities both at the time of purchase and later on. Previously, changing a radio’s features and capabilities meant significant modifications, or buying a new radio.

    Chapter 2 Basic Maintenance Introduction This section of the manual describes preventive maintenance, handling precautions, and some basic repair procedures and techniques. Each of these topics provides information vital to the successful operation and maintenance of your radio. Preventive Maintenance Radios are shipped from the factory with a worst-case frequency error of ±200 Hz for VHF, ±300 Hz for UHF, and ±500 Hz for 800 MHz.

  • Page 48: Cleaning External Plastic Surfaces

    • Disconnect all power from the unit before ESD-sensitive components are removed or inserted unless otherwise noted. • Use a static-safeguarded workstation, through the use of an anti-static kit (Motorola part number 01-80386A82). This kit includes a wrist strap, two ground cords, a static-control table mat and a static-control floor mat.

  • Page 49

    • Make skin contact with a conductive work surface first and maintain this contact when the device is set down or picked up. • Always wear a conductive wrist strap when servicing this equipment. The Motorola part number for a replacement wrist strap that connects to the table mat is 42-80385A59.

  • Page 51: Chapter 3 Basic Theory Of Operation

    Chapter 3 Basic Theory of Operation Introduction The following theory will help isolate the problem to a particular board. Using circuit board replacement as the basic service approach maximizes the working time of the radio. General Overview The ASTRO Digital Spectra and Digital Spectra Plus radios are wideband, synthesized, fixed-tuned radios.

  • Page 52: Analog Mode Of Operation

    Basic Theory of Operation: Analog Mode of Operation Analog Mode of Operation 3.3.1 Receive Operation When the radio is receiving, the signal comes from the antenna/antenna-switch on the power amplifier board to the front-end receiver assembly. The signal is then filtered, amplified, and mixed with the first local-oscillator signal generated by the voltage-controlled oscillator (VCO).

    Basic Theory of Operation: Power Amplifier 3.5.8 Vehicle Interface Port (VIP) 3.5.8.1 Remote-Mount The VIPs allow the control head to operate outside circuits and to receive inputs from outside the control head. There are three VIP outputs that are used for relay control. There are also three VIP inputs that accept inputs from switches.

  • Page 55: Power Control

    Basic Theory of Operation: Front-End Receiver Assembly 3.6.2 Power Control A directional coupler and detector network controls power. It senses the forward power from the last gain stage and feeds the detected voltage back to the command board control circuitry, where it is compared to a reference voltage set during power-set procedures.

  • Page 56: Voltage-controlled Oscillator (vco)

    Basic Theory of Operation: Voltage-Controlled Oscillator (VCO) Synthesizing for the first and second VCO is performed by the prescaler and synthesizer ICs. These ICs are programmed through a serial data bus from signals generated on the VOCON board. A dc voltage, generated on the command board, sets the synthesizer’s reference oscillator frequency of 16.8MHz.

  • Page 57

    Basic Theory of Operation: VOCON (Vocoder/Controller) Board The regulator and power control circuits include an unswitched +5V discrete circuit and the regulator/ power control IC, which produces both switched +5V and 9.6V. The unswitched +5V source is used as a reference for its switched +5V source. Filtered unswitched +5V is used for the microcontrol circuits.

  • Page 58

    Basic Theory of Operation: VOCON (Vocoder/Controller) Board The VOCON board controls receive/transmit frequencies, the display, and various radio functions, using either direct logic control or serial communication to external devices. The connector J801 provides an interface between the encryption module and the VOCON board for encrypting voice messages.
