Chapter 1 Introduction This manual contains information needed for Levels One and Two radio servicing. Level One servicing consists of radio programming, radio alignment, and installation and removal of the antenna, belt clip, battery, and universal connector cover. Level Two servicing covers disassembly and reassembly of the radio to replace circuit boards.
Introduction: Radio Description Radio Description The ASTRO APX 3000 radio provides improved voice quality across more coverage area. The digital process, called embedded signaling, intermixes system signaling information with digital voice, resulting in improved system reliability and the capability of supporting a multitude of advanced features.
General Maintenance In order to avoid operating outside the limits set by the FCC, align the ASTRO APX 3000 radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first. (See Reference Oscillator Alignment).
Page 32
Never touch the equalization vent. Ensure that no oily substances come in contact with this vent. • The APX 3000 radio is designed to be submerged to a maximum depth of 1 meter, with a maximum submersion time of 30 minutes. Exceeding either maximum limit may result in damage to the radio.
Chapter 3 Basic Theory of Operation This chapter discusses the basic operational theory of the ASTRO APX 3000 radio, which is a wideband, synthesized radio available in the UHF1 (380–470 MHz), UHF2 (450–520 MHz), VHF (136–174 MHz) and 764–870 MHz frequency bands. All ASTRO APX3000 radios are capable of both analog operation (12.5 kHz or 25 kHz bandwidths), ASTRO mode (digital) operation (12.5 kHz...
Basic Theory of Operation: Analog Mode of Operation Analog Mode of Operation This section provides an overview of the analog mode receive and transmit theory of operation. 3.2.1 Receiving The RF signal is received at the antenna and is routed through the Harmonic Filter, followed by the Antenna Switch and finally the 15dB Step Attenuator IC.

Both filters are discrete and tunable designs and are used to band limit the incoming energy and suppress known spurious responses such as Image and the ½...
Basic Theory of Operation: Analog Mode of Operation 3.2.2 Transmitting When the radio is transmitting, microphone audio is digitized and then processed by the DSP and sent to the Trident IC (see Figure 3-7, Figure 3-8 Figure 3-9) via the SSI interface. The Trident IC processes the SSI data for application to the voltage controlled oscillator as a modulation signal.

Basic Theory of Operation: Digital (ASTRO) Mode of Operation Digital (ASTRO) Mode of Operation In the ASTRO (digital) mode of operation, the transmitted or received signal is limited to a discrete set of frequency deviation levels. The receiver handles an ASTRO-mode signal identically to an analog-mode signal, up to the point where the DSP decodes the received data.
Page 40
Basic Theory of Operation: Controller Section The ARM controller core of the OMAP processor handles the power up sequence of all devices, including firmware upgrades, and all operating system tasks that are associated with FLASH and SDRAM memories and user interface communication. The FLASH memory (64 MB) is required to store the firmware, tuning, and Codeplug settings, which upon initialization get read and stored into SDRAM (32MB) for execution.
The “Characteristics” column is included so that equivalent equipment may be substituted; however, when no information is provided in this column, the specific Motorola model listed is either a unique item or no substitution is recommended.
These kits and/or parts are available from the Radio Products and Solutions Organization offices listed in Replacement Parts Ordering. While all of these items are available from Motorola, most are standard shop equipment items, and any equivalent item capable of the same performance may be substituted for the item listed.
Chapter 5 Performance Checks This chapter covers performance checks used to ensure that the ASTRO APX 3000 radio meets published specifications.

5.2.2 RF Test Mode When the ASTRO APX 3000 radio is operating in its normal environment, the radio's microcomputer controls the RF channel selection, transmitter key-up, and receiver muting, according to the customer codeplug configuration. However, when the unit is on the bench for testing, alignment, or repair, it must be removed from its normal environment using a special routine, called RF TEST MODE.

Chapter 6 Radio Alignment Procedures This chapter describes both receiver and transmitter radio alignment procedures. Test Setup A personal computer (PC) and tuner software are required to align the radio. Refer to the applicable manual for installation and setup procedures for the software. To perform the alignment procedures, the radio must be connected to the PC and to a universal test set.
Radio Alignment Procedures: Tuner Main Menu Tuner Main Menu › › › Select Tuner from the START menu by clicking Start Program Files Motorola › › ASTRO 25 Products ASTRO 25 Tuner. To read the radio, use the File Read Device menu or click on Figure 6-2 illustrates how the alignment screens are organized.
Radio Alignment Procedures: Softpot Figure 6-3. Typical Softpot Screen Adjusting the softpot value sends information to the radio to increase (or decrease) the voltage in the corresponding circuit. For example, left-clicking the UP spin button in the New Softpot Value scroll box on the Reference Oscillator screen instructs the radio’s microcomputer to increase the voltage across a varactor in the reference oscillator, which increases the frequency.
Radio Alignment Procedures: Radio Information Radio Information Figure 6-4 shows a typical Radio Information screen. This screen is informational only and cannot be directly changed. Figure 6-4. Radio Information Screen Transmitter Alignments 6.5.1 Reference Oscillator Alignment Adjustment of the reference oscillator is critical for proper radio operation.

Disassembly/Reassembly Procedures: Ensuring Radio Submergibility 8-25 8.7.7 Immersibility Test Immersibility testing the radio is necessary only if the radio has failed the vacuum test. Do not perform the test until the vacuum test has been completed. Immersibility test involves creating sealed condition inside the radio, submerging the radio in water, and observing the radio for a stream of bubbles (leak).
8-26 Disassembly/Reassembly Procedures: Ensuring Radio Submergibility 8.7.8 Troubleshooting Leak Areas Before repairing any leak, first read all of the steps within the applicable section. This will help to eliminate unnecessary disassembly and reassembly of a radio with multiple leaks. NOTE: All disassembly and reassembly methods can be found in Section 8.4.

FLASHcodes are only applicable for radios which are upgradeable through the FLASHport process. FLASHport A Motorola term that describes the ability of a radio to change memory. Every FLASHport radio contains a FLASHport EEPROM memory chip that can be software written and rewritten to, again and again.
