1.3 Radio Description

The ASTRO APX 7000 radios are among the most sophisticated two-way radios available. These dual band radios are capable of operating in both VHF (136–174 MHz) and 764–870 MHz frequency bands, UHF1 (380–470 MHz) and 764–870 MHz frequency bands, VHF (136–174 MHz) and UHF1 (380–470 MHz) frequency bands, UHF2 (450–520 MHz) and 764–870 MHz frequency bands, and, VHF (136–174 MHz) and UHF2 (450–520 MHz) frequency bands.

The ASTRO APX 7000 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.

ASTRO APX 7000 radios are available in two configurations – Top Display and Dual Display.

The ASTRO APX 7000 radio utilizes Motorola’s 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. But now, similar to how a computer can be loaded with different software, the radio’s features and capabilities can be upgraded with FLASHport software.

Chapter 2 Basic Maintenance

This chapter describes preventive maintenance and handling precautions. Each of these topics provides information vital to the successful operation and maintenance of your radio.

2.1 General Maintenance

In order to avoid operating outside the limits set by the FCC, we recommend that you align the ASTRO APX 7000 radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first. (See Section “6.5.1 Reference Oscillator Alignment” on page 1:6-4). Periodic visual inspection and cleaning is also recommended.

For APX 7000 R (Ruggedized) Radios – Radio submergibility should be checked annually by qualified service technicians.

2.1.1 Inspection

Check that the external surfaces of the radio are clean and that all external controls and switches are functional. A detailed inspection of the interior electronic circuitry is not needed.

2.1.2 Cleaning

The following procedures describe the recommended cleaning agents and the methods to be used when cleaning the external surfaces of the radio. External surfaces include the housing assembly and battery case. These surfaces should be cleaned whenever a periodic visual inspection reveals the presence of smudges, grease, and/or grime.

The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild dishwashing detergent in water.

The effects of certain chemicals and their vapors can have harmful results on certain plastics. Aerosol sprays, tuner cleaners, and other chemicals should be avoided.

The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should be used to remove the solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices.

2.2 Handling Precautions

Complementary metal-oxide semiconductor (CMOS) devices, and other high-technology devices, are used in this family of radios. While the attributes of these devices are many, their characteristics make them susceptible to damage by electrostatic discharge (ESD) or high-voltage charges. Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special precautions must be taken to prevent device damage during disassembly, troubleshooting, and repair. Handling precautions are mandatory for this radio, and are especially important in lowhumidity conditions.

Page 32

Sec 1: 2-2 Basic Maintenance: Handling Precautions

• The APX 7000 radio has a vent port that allows for pressure equalization in the radio. Never poke this vent with any objects, such as needles, tweezers, or screwdrivers. This could create a leak path into the radio and, in the case of APX 7000 R radios, the radio’s submergibility will be lost.

• The pressure equalization vent is located under the main speaker grille near the top left side. Never obstruct or cover the small opening on the top left with any object, including a label. Ensure that no oily substances come in contact with this vent.

•(APX 7000 R Radios Only) The APX 7000 R radio is designed to be submerged to a maximum depth of six (6) feet, with a maximum submersion time of 2 hours per U.S. MIL-STD. Exceeding either maximum limit may result in damage to the radio. For specific U.S. MIL-STD details, see Section “8.10 Ensuring Radio Submergibility” on

page 1:8-39.

2.2.1 APX 7000 R Radios Only

If the radio battery contact area has been submerged in water, dry and clean the radio battery contacts before attaching a battery to the radio. Otherwise, the water could short-circuit the radio.

If the radio has been submerged in water, shake the radio briskly so that any water that is trapped inside the speaker grille and microphone port can be removed. Otherwise, the water will decrease the audio quality of the radio.

Page 33

Chapter 3 Basic Theory of Operation

This chapter discusses the basic operational theory of the ASTRO APX 7000 radio, which is a wideband, synthesized radio available in the VHF (136–174 MHz), UHF1 (380–470 MHz), UHF2 (450–520 MHz), 764 to 870 MHz, VHF/764 to 870 MHz, UHF1/764 to 870 MHz and VHF/ UHF1, UHF2/764 to 870 MHz and VHF/UHF2, frequency bands.

3.2 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 Auxiliary and Multi Switch (SP3T) ICs. The latter contains a switchable attenuator that is enabled at predetermined RF power thresholds present at the antenna port. The output of the Multi-switch IC is applied to the first SPST band select switch to select the either the VHF or 700,800 bands (see Figure 3-3), UHF1 or 700,800 bands (see Figure 3-4), VHF/UHF1 bands (see Figure 3-5), UHF2 or 700,800 bands (see Figure 3-6) and VHF or UHF2 bands (see Figure 3-7).

The GPS signal is tapped at the antenna port via a series resonant network which provides a very low capacitive load to the transceiver. The signal is routed though a GPS LNA and it's output is applied to the RF-Controller interface connector where it is eventually routed to the expansion board for processing by the GPS IC.

The GPS receiver is setup in an autonomous one track always (OTA) mode, also known as continuous navigation. This means the GPS will continuously track satellites for as long as the radio is powered to ensure the best possible accuracy. In the event the radio loses visibility of the satellites due to terrain or environmental factors such as driving through a tunnel or entering a building, the GPS will temporarily lose its position fix. A power savings algorithm will then cycle the GPS in and out of a sleep mode at approximately 90 second intervals until the radio has moved back into an environment where GPS signals are present.

The user will be able to view the current latitude, longitude, and time/date stamp on the radio’s display. The radio can also be configured to send its’ location to the system at predetermined intervals (LRRP). Depending on system options, the user may be able to enable/disable the GPS receiver.

3.2.1.2 VHF Front-End

From the first band select switch, a VHF signal is routed to the first pre-selector filter followed by an LNA and a second pre-selector filter. Both filters are discrete and fixed designs and are used to band limit the incoming energy and suppress known spurious responses such as Image and the ½ IF spur. The output of the second pre-selector filter is applied to the RF port of the Mixer IC via a second VHF/700,800 band select switch. The Mixer IC is also excited by a Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz intermediate frequency (IF). The down converted IF signal is passed through a crystal filter and IF amplifier which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).

3.2.1.3 700/800 MHz Front-End

From the first band select switch, a 700 MHz or 800 MHz band signal is routed to a second band SPST switch which selects the 700 or the 800 band signal and routes it to the appropriate first pre-selector filter. A third band select switch selects the output of the appropriate filter and applies it to an LNA followed by a similar pre-selector filter/ band-select switch circuit. The signal is then routed to second LNA whose output is applied to a discrete image filter. Both preselector filters are Surface Acoustic Wave designs used to band limit the received energy and suppress known spurious responses such as Image and the ½ IF spur. The output of the discrete image filter is applied to the RF port of the Mixer IC via a second VHF/700,800 band select switch. The Mixer IC is also excited by a Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz intermediate frequency (IF). The down converted IF signal is passed through a crystal filter and IF amplifier which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).

3.2.1.4 UHF1 Front-End

From the first band select switch, a UHF1 signal is routed to the first pre-selector filter followed by an LNA and a second pre-selector filter. Both filters are discrete and tunable designs and are used to band limit the incoming energy and suppress known spurious responses such as Image spur. The output of the second pre-selector filter is applied to the RF port of the Mixer IC via a second UHF1/700,800 or UHF1/VHF band select switch. The Mixer IC is also excited by a Local Oscillator (LO) signal at the LO port to down-convert the RF signal to a 109.65 MHz intermediate frequency (IF). The down converted IF signal is passed through a crystal filter and IF amplifier which drives the input of the Abacus 3 Analog to Digital Converter IC (AD9864).

3.2.1.5 UHF2 Front-End

From the first band select switch, U1122, a UHF1 signal is routed to the first pre-selector filter followed by a Low Noise Amplifier (LNA) and a second pre-selector filter. Both filters are discrete and tunable designs and are used to band limit the incoming energy and suppress known spurious responses such as Image spur. The LNA active device is an NPN transistor (U1932) with active bias provided by transistor pair Q1922. The output of the second pre-selector filter is applied to a discrete Low Pass Filter (LPF). The output of the LPF is applied to the RF port of the Mixer IC via a second band select switch, U501. The Mixer IC, U506, is driven by a Local Oscillator (LO) signal generated by the Trident synthesizer IC, U702, at the LO port to down-convert the RF signal to a 109.65 MHz intermediate frequency (IF). It is a passive, high linearity design with balanced inputs at the RF and IF ports and internal LO buffer. The down converted IF signal is passed through a 3-pole crystal filter, FL501, and an IF amplifier, Q503, which drives the input of the Analog to Digital Converter IC, U601.

Page 39

Basic Theory of Operation: Analog Mode of Operation Sec 1: 3-7

3.2.1.6 Analog To Digital Converter

The ADC IC's front end down converts the first IF to a second IF, a 2.25 MHz signal. The second IF is sampled at 18 MHz, a signal generated by an integrated clock synthesizer. The sampled signal is decimated by a factor of 900 to 20 kHz and converted to SSI format at the ADC's output. The Serial Synchronous Interface (SSI) serial data waveform is composed of a 16 bit in-phase word (I) followed by a 16 bit Quadrature word (Q). A 20 kHz Frame Synch and a 1.2 MHz clock waveform are used to synchronize the SSI IQ data transfer to the Digital Signal Processor IC (OMAP) for post-processing and demodulation.

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 3-9 to Figure 3-13) via the SSI interface. The Trident IC processes the SSI data for application to the voltage controlled oscillator as a modulation signal.

3.2.2.1 VHF Transmit

Once a VHF frequency for transmit has been selected, the Trident IC and its accompanying logic circuitry enable the correct voltage controlled oscillator which then generates the desired transmit frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the signal. An RF switch then routes the signal to the VHF Driver amplifier and then to the discrete final stage. The signal is then filtered by a harmonic filter and passed through a RF switch into a directional coupler. The Log Amp power detector monitors the output of the directional coupler and adjusts the control voltages to the driver amplifier and the discrete final. Finally, the RF signal comes to a Single Pole double throw (SP2T) RF switch which can route the power to the main antenna or to the Universal Connector port of the radio.

3.2.2.2 700/800 MHz Transmit

Once a 700/800 MHz frequency for transmit has been selected, the Trident IC and its accompanying logic circuitry enable the correct voltage controlled oscillator which then generates the desired transmit frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the signal. An RF switch then routes the signal to the 700/800 MHz Driver amplifier and then to the discrete final stage. The signal is then filtered by a harmonic filter and passed through a RF switch into a directional coupler. The Log Amp power detector monitors the output of the directional coupler and adjusts the control voltages to the driver amplifier and the discrete final. Finally, the RF signal comes to a SP2T RF switch which can route the power to the main antenna or to the Universal Connector port of the radio.

3.2.2.3 UHF1 Transmit

Once a UHF frequency for transmit has been selected, the Trident IC and its accompanying logic circuitry enable the correct voltage controlled oscillator which then generates the desired transmit frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the signal. An RF switch then routes the signal to the UHF1 Driver amplifier and then to the discrete final stage. The signal is then filtered by a harmonic filter and passed through a RF switch into a directional coupler. The Log Amp power detector monitors the output of the directional coupler and adjusts the control voltages to the driver amplifier and the discrete final. Finally, the RF signal comes to a Single Pole double throw (SP2T) RF switch which can route the power to the main antenna or to the Universal Connector port of the radio.

3.2.2.4 UHF2 Transmit

Once a UHF frequency for transmit has been selected, the Trident IC and its accompanying logic circuitry enable the correct voltage controlled oscillator which then generates the desired transmit frequency. This transmit signal is then routed to the TX buffer amplifier which amplifies the signal. An RF switch then routes the signal to the UHF2 Driver amplifier and then to the discrete final stage. The signal is then filtered by a harmonic filter and passed through a RF switch into a directional coupler. The Log Amp power detector monitors the output of the directional coupler and adjusts the control voltages to the driver amplifier and the discrete final. Finally, the RF signal comes to a Single Pole double throw (SP2T) RF switch which can route the power to the main antenna or to the Universal Connector port of the radio.

3.3 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. In the ASTRO receive mode, the DSP uses a different algorithm to recover data.

In the ASTRO transmit mode, microphone audio is processed identically to an analog mode, with the exception of the algorithm the DSP uses to encode the information. Using this algorithm, transmitter FM deviation is limited to discrete levels.

Basic Theory of Operation: Controller Section Sec 1: 3-11

3.4 Controller Section

The controller section (see Figure 3-14) comprises of five functional sections that are split among three boards, which are the VOCON, EXPANSION and OPTION boards. The main functional section consists of a dual core ARM and DSP controller, an encryption processor (MACE), Flash memory, and a Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM). The Power and Clocks section includes a power management IC (MAKO) and various external switching regulators, and two clock sources (12 Mhz and 24.576 Mhz) from which all other controller digital clocks are derived. The Audio section has a CODEC and a class-D audio power amplifier that provides the radio with a multiple microphone, multiple speaker design. The User Interface section provides communication and control to the top and main Liquid Crystal Displays (LCD) on the radio, as well as a keypad and a side connector interface conforming to Universal Connector specifications. The Expansion Memory, GPS and Option section comprises of a Micro SD memory interface, Global Positioning Satellite (GPS) processor, and an Option Board for radio feature upgrades.

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 (32 MB) for execution. The ARM and DSP core jointly control and configure audio, wireless and RF devices linked to the Serial Peripheral Interface (SPI) and Synchronous Serial Interface (SSI) buses to enable radio FM and optional wireless communication protocols. For encryption, a separate ARM processor is used (MACE) to encode and decode encryption packets coming in from the main OMAP processor through the SSI interface. Its firmware is flashed via the main processor during an upgrade request to its internal FLASH memory.

Figure 3-14. Controller Block Diagram

Page 44

Sec 1: 3-12 Basic Theory of Operation: Controller Section

The power and most clocks to the controller devices are provided by the MAKO IC and external switching and linear regulators on board. A Complex Programmable Logic Array (CPLD) IC divides the 24.576 Mhz clock from MAKO to source OMAP's 32 kHz Real Time Clock, and MACE's 4 Mhz main clock. OMAP's main clock is supplied externally from an on board 12 Mhz crystal.

The radio has two internal microphones and two internal speakers, as well as available microphone and speaker connections for external accessories. The main external speaker is located opposite to the main display and keypad of the radio. It can deliver a rated power of 1W on a ~4 Ohms speaker, while the smaller "data" speaker can only deliver 0.5 W of power on a load of 16 Ohms. Both internal and external microphones use the CODEC's AD to deliver digital audio samples to the DSP controller. The main speaker is driven by the class D PA on the expansion board, while the data and external speakers are driven by the AB type PA on MAKO. Both speaker paths use the CODEC for volume control and to convert audio from digital to analog.

The user interface block consists of a top and main or "data side" display, a keypad, top controls and the accessory side connector. The side connector (Universal Connector) provides audio, USB, RS232 and RF communication for accessories. All signals to and from the connector go through the internal expansion board before reaching the microcontroller and other devices on the main board.

The radio also has an expansion bay for a Micro SD memory card, a Global Positioning System (GPS) interface, and an option slot for radio feature upgrades. The memory card can be inserted on the bay near the battery connector of the radio. The option slot of the radio is available internally to the radio, and it is not hot swappable by the user. The option slot is available through a connector directly linked to the main controller board.

order from top to bottom

DO NOT switch radios in the middle of any alignment procedure. Always left-click the Close button on the screen to return to the Main Menu screen before disconnecting the radio. Improper exits from the alignment screens might leave the radio in an improperly configured state and result in seriously degraded radio or system performance.

Page 63

Radio Alignment Procedures: Softpot Sec 1: 6-3

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.

In ALL cases, the softpot value is just a relative number corresponding to a digital-to-analog (D/A) generated voltage in the radio.

Perform the following procedures in the sequence indicated.

NOTE: Some of the following screens may vary depending upon the radio under test and the version

of tuner software you are using. Refer to the software’s online help.

When keying the radio during a test, always dummy load.

6.5.1 Reference Oscillator Alignment

Adjustment of the reference oscillator is critical for proper radio operation. Improper adjustment will result not only in poor operation, but also in a misaligned radio that will interfere with other users operating on adjacent channels. For this reason, the reference oscillator should be checked every time the radio is serviced, or once a year, whichever comes first. The frequency counter used for this procedure must have a stability of 0.1 ppm (or better).

NOTE: Reference oscillator alignment is required after replacing (or servicing) the transceiver board.

This test can be done with either the R-2670 Communication Analyzer or the 8901_ Modulation Analyzer.

• Initial setup using the R-2670 Communication Analyzer:

- RF Control: MONITOR

-B/W: WB

- Freq: CPS frequency under test

- Attenuation: 20dB

- Mon RF in: RF I/O

- Meter: RF Display

- Mode: STD

- Input Level: uV or W

- Display: Bar Graphs

- Squelch: Mid-range or adjust as necessary

6.5.5 Transmit Deviation Balance Alignment

This alignment procedure balances the modulation contributions of the low- and high-frequency portions of a baseband signal. Proper alignment is critical to the operation of signalling schemes that have very low frequency components (for example, DPL) and could result in distorted waveforms if improperly adjusted.

This procedure needs to be performed at multiple frequencies to allow for proper alignment across the entire RF band. The RF band is divided into frequency zones with a calibration point (value) in each zone.

NOTE: This alignment is required after replacing (or servicing) the VOCON board or the transceiver

board.

Proper alignment requires a modulation analyzer or meter with a frequency response to less than 10 Hz modulating frequency. The modulation analyzer settings during this test should be set for average deviation, a 15 kHz low-pass filter, no de-emphasis, and no high-pass filter, if these settings are supported.

This alignment can be done with either the R-2670 Communication Analyzer or the 8901_ Series Modulation Analyzer. The method of choice is the R-2670 analyzer.

1. Initial setup using the R-2670 Communication Analyzer:

- Connect a BNC cable between the “DEMOD OUT” port and the “VERT/SINAD DIST/DMM COUNTER IN” port on the R-2670.

-Press the SPF key on the R-2670 to display the “SPECIAL FUNCTIONS MENU.” Move the cursor to “High Pass,” and select 5 Hz on the soft key menu. Select 20 kHz for the “Low Pass” setting.

- In the “RF Control” section of the R-2670, move the cursor to the “B/W” setting and select “WIDE +/- 100 kHz” on the soft key menu.

- Place the R-2670 cursor in the “Display” zone. Select “AC VOLTS” on the soft key menu. Move the cursor to the “Range” setting and select “AUTO.”

2. Initial setup using the 8901_ Series Modulation Analyzer:

-Press the FM MEASUREMENT button. (The “Error 03-input level too low” indication is normal until an input signal is applied.)

- Simultaneously press the Peak – and Peak + buttons. Both LEDs on the buttons should light.

- Press the 15 kHz LP filter key.

3. Select the TX Deviation Balance alignment screen. The screen indicates the transmit

frequencies to be used. See Figure 6-23, Figure 6-24, Figure 6-25, Figure 6-26 and

Figure 6-27.

4. In the "RF Control" section of the R2670, set the service monitor to the desired frequency (as shown in the frequency list in the TX Deviation Balance alignment screen).

5. Left-click the PTT Tone: Low button.

6. Left-click the slider of the frequency selected (should be the same frequency as step 4).

7. Left-click the PTT Toggle button on the screen to make the radio transmit. The screen indicates whether the radio is transmitting.

Chapter 7 Encryption

This chapter provides procedures for using the encryption capability of your radio. The following procedures are outlined:

• Loading an encryption key

• Selecting an encryption key

• Selecting an Index (only applicable to Dual Display configured radios)

• Erasing an encryption key (only applicable to Dual Display configured radios)

7.1 Load an Encryption Key

Keys will be loaded from the KVL to the radio in either clear or encrypted form depending on the configuration of the CPS parameter "KVL – FIPS Level 3 Approved Mode". If the parameter is disabled, keys will be sent in clear form; if the parameter is enabled, keys will be sent to the radio in encrypted form.

NOTE: A KVL3000 Plus with software version R03.52.45 or greater must be used to load keys to a

radio with "KVL – FIPS Level 3 Approved Mode" enabled.

To load an encryption key:

1. Refer to the key-variable loader (KVL) manual for equipment connections and setup.

2. Attach the KVL to the radio. The top display shows “KEYLOAD” whereas “KEYLOADING” is

shown on the front display of a Dual Display configured radio. All other radio functions, except for power down, backlight, and volume, are locked out.

3. Refer to the KVL manual for how to load the encryption keys into the radio.

4. When the key is loaded successfully, you will hear:

• On single-key radios – a short tone.

• On multikey radios – an alternating tone.

7.2 Multikey Feature

This feature allows the radio to be equipped with multiple encryption keys. It can support two or more encryption algorithms simultaneously (e.g., AES and DES-XL).

• Conventional Multikey – The encryption keys can be tied (strapped), on a one-per-channel

basis. In addition, the radio can have operator-selectable keys, operator-selectable indices, and operator-selectable key erasure. If talkgroups are enabled in conventional, then the encryption keys are strapped to the talkgroups.

• Trunked Multikey – If the radio is used for both conventional and trunked applications, strap

the encryption keys for trunking on a per- talkgroup or announcement group basis. In addition, a different key can be strapped to other features; for example, dynamic regrouping, failsoft, or emergency talkgroup. The radio can have operator-selectable key erasure.
