Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed or otherwise congured for electromagnetic compatibility. FACILITIES To avoid electromagnetic interference and/or compatibility conicts, turn off your radio in any facility where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy. FIXED SITE ANTENNAS Transportable Repeater equipment is transported to and then set up at a xed location and operated as a xed control station or repeater. The antenna installation must comply with the following requirements in order to assure optimal performance and make sure human exposure to radio frequency electromagnetic energy is within the guidelines set forth in the above standards:
The antenna must be mounted outside the building. Mount the antenna on a tower if at all possible. The lowest point of the antenna must be elevated a minimum of 10 meters above the ground. This may require the use of a coaxial cable extension for the antenna. If the antenna is to be mounted on a building, then it must be mounted on the roof. If the antenna supplied with the repeater is used and the repeater cannot be located within the 12 ft. cable length, then a coaxial cable extension should be used. As with all xed site antenna installations, it is the responsibility of the licensee to manage the site in accordance with applicable regulatory requirements and may require additional compliance actions such as site survey measurements, signage, and site access restrictions in order to insure that exposure limits are not exceeded. 2-2 68P81093C75-A Introduction General 3

, and Station Control Module The Station Control Module is microprocessor-based and features extensive use of ASIC and digital signal processing technology. The module serves as the main controller for the station, providing signal processing and operational control for the station modules. 68P81093C75-A 3-1 Wireline Circuitry The station wireline circuitry provides a wide variety of telephone interfaces, including analog,
, SECURENET Tone Remote Control, and DC Remote Control. Telephone line connections are easily made to the wireline circuitry via connectors on the top panel.
, ASTRO CAI ASTRO Switching Power Supply The station features a switching-type power supply, accepting a wide range of AC inputs (85-265 VAC, 49-61 Hz). The power supply generates 13.8 VDC for the station modules.

The station is identical in operation to the Quantar station, hence there is no local control capability. There is no digital-to-audio translation within the station. Local control style operation can be accomplished in several ways:
a. A portable radio may be used as an RF control station talking to the repeater. b. The station may be equipped with the wireline and the modem options and routed through a DIU to a tone remote console. The Tone remote console controls the station via wireline through the DIU. The wireline in this case is a local 4-wire cable. External Duplexer Operation The PDR 3500 must be used with an external duplexer when frequency spacing is less than 3 MHz. The duplexer isolation required for proper operation is approximately 60 dB. Double-
shielded coaxial cables must be used from the repeater to the duplexer. Repeater RA or Cross Band Repeater Operation The PDR 3500 can be congured for Repeater RA or cross band repeater operation by adding the wireline card and the Astro modem to the each repeater. The repeaters are connected together using the wireline port on each repeater. The cables are terminated in RJ-45 connectors. Repeater 1 Wireline A Wireline B Repeater 2 Wireline A Wireline B NOTE:

For a complete description of the Hardware Conguration elds, please refer to the Quantar RSS Users Guide
(68P81085E35). 68P81093C75-A 7-3 Channel Information From the Main Menu, press F4. Press F4 again to arrive at the Channel Information Screen. From this screen, the user may congure the TX and RX frequencies, RF power out, modulation type, and the various channel traits for up to 16 channels. 1. In this screen, rst set the Rx1 and Tx frequencies to the proper values. NOTE:
The Rx2 frequency is set to 0.00000 MHz and cannot be edited. This is because the PDR 3500 does not support 2 receivers. The station will automatically calculate the Tx Idle Frequency based on the TX-RX spacing for the channel. In most applications, the TX Idle Frequency will be the same as the Tx Frequency. However, in case of portable or mobile radios unsquelching near the PDR 3500, adjust the Tx Idle Frequency to the Tx Frequency -6.25kHz. 2. Set the modulation type to either Analog, ASTRO, ASTRO CAI, Analog/ASTRO CAI, or CAI RX WIDE DEV. 3. Move to page 2 of the Channel Information Screen by pressing Normal Tx Power Out the Page Down key. Set the desired power level, unless the station being programmed is UHF R3 or UHF R4. If the station transmitter is UHF R3 or UHF R4, the power output must be translated using Table 6 due to a difference between the power range in RSS and the actual power range of the station. to the All bands except UHF R3 and UHF R4 use the low power Quantar station prole, meaning the station is RSS programmed as a low power station, and the actual output power of the station matches what is programmed in RSS. For UHF R3 and UHF R4, however, there is no low power Quantar prole, so the high power prole is used. Thus, all power settings in RSS for those bands are based on a range of 20-120W for R3 and 20-110W for R4. Since the actual output power of the PDR 3500 is 5-30W for R3 and 5-25W for R4, Table 6 must be used to translate actual power into RSS power. The Actual Power column corresponds to the power out of the PDR 3500 while the RSS Power column corresponds to power levels to be entered in RSS during the alignment process. For example, to set a UHF R3 station to transmit at 15 watts, 60 should be entered in the eld of RSS, as specied in Table 6. Normal Tx Power Out 7-4 68P81093C75-A Table 6.

(Threshold depends on station Tx frequency band.) Alarm is cleared when DC voltage returns to normal. Alarm is reported when PA fails to keyup to full ouput power. Alarm is cleared upon successful keyup to full power. Alarm is reported when either Tx or Rx synthesizers fail to lock. Alarm is cleared when both sythesizers lock. Should not occur in PDR 3500. 68P81093C75-A 9-9 Verifying Transmitter Circuitry Introduction While most module faults can be detected by running the station diagnostics provided by the RSS, the following procedure provides a more traditional method of troubleshooting the transmitter circuitry. This procedure is useful in the event that the RSS is not at hand or for some reason cannot be utilized (PC malfunction, etc.) This procedure allows the service technician to make minor adjustments and verify the proper operation of the station transmit circuitry, including:
Exciter Module Power Amplier Module Intermediate Power Amplier Module (800 MHz stations only) Power Supply Module 2.1 MHz Reference Oscillator Circuitry Transmitter-related circuitry on the Station Control Module (SCM) and Backplane board In general, the transmitter circuitry is exercised by injecting and measuring signals using a Motorola R2001 Communications Analyzer (or equivalent). Measured values outside the acceptable range indicate a faulty module; values within range verify proper operation of the above listed modules and circuitry. Required Test Equipment The following test equipment is required to perform the procedure:
Motorola R2001 Communications Analyzer (or equivalent) Telephone-style handset with PTT switch (TMN6164, or equivalent) In-line Wattmeter (Motorola Model S-1350, or equivalent) Dummy Load (50

Intermediate Power Amplier Module failure
(800 MHz stations only)
- Exciter Module failure
- Loose or bad Exciter-to-PA RF cable
- DIP switches on backplane are set for incorrect station frequency band. DIP switches should be set as described in the backplane portion of the Module Replacement section.
- Faulty forward voltage, control voltage, or temperature voltage translation circuitry on backplane. If TX Lock LED is off, suspect the following:
- Faulty Station Control Module
- Faulty Exciter Module
- Faulty backplane Step 4. Measure output power by pressing the PTT button and observing the reading on the in-line wattmeter. If the PA output is not at the proper power (as set for the particular station), align the output power as described in the Setup and Connections section of this manual. If the station will not output the rated power, and the output is being measured through a duplexer or antenna relay, the duplexer could be set for the incorrect frequency, or it could be malfunctioning, or the antenna relay could be faulty. Connect the wattmeter directly to the transmit port (UHF connector) on the station top panel, bypassing the duplexer or antenna relay. If the station generates rated power directly from the PA, suspect the following:
- Faulty duplexer or transmit frequency mismatch
- Loose or faulty PA-to-duplexer/antenna relay cable
Improperly connected or faulty antenna relay 9-12 68P81093C75-A If the station still does not generate rated power, suspect the following:
- Power Amplier Module failure
Intermediate Power Amplier Module failure
(800 MHz stations only)
- Exciter Module failure
- Loose or faulty Exciter-to-PA RF cable
- Faulty forward voltage or control voltage translation circuitry on backplane Step 5. If the PA power out is okay, setup R2001 for spectrum analyzer display. Press the PTT button and observe the display. The display should look similar to:
If the display shows multiple carriers, evenly spaced about the station transmit frequency, suspect a faulty PA module or IPA module
(800 MHz stations only). If the display shows a solid carrier, but off frequency, suspect the following:
- Faulty Exciter or Station Control Module If the display shows a single carrier moving erratically, suspect the following:
- Faulty Station Control Module
- Faulty Exciter Module
- Faulty PA Module Step 6. If the display is okay, setup R2001 to display modulation. Using the handset, push the PTT button and speak into the mouthpiece. Verify that the display shows:
If the proper display is not obtained, suspect faulty SCM or Exciter Module Step 7. Set the R2001 for GEN/MON MTR. Press the PTT button and speak loudly into the mouthpiece to cause maximum deviation. Display should read 5 kHz maximum. 68P81093C75-A 9-13 Verifying Receiver Circuitry If the proper display is not obtained, suspect faulty SCM or Exciter Module Step 8. This completes the Verifying Transmitter Circuitry test procedure. If all displays and measurements are correct, the transmitter circuitry may be considered to be operating properly. Remove test equipment. Restore the station to normal service. Return to the trouble shooting ow chart to resume the troubleshooting sequence. Introduction While most module faults can be detected by running the station diagnostics provided by the RSS, the following procedure provides a more traditional method of troubleshooting the receiver circuitry. This procedure is useful in the event that the RSS is not at hand, or, for some reason, cannot be utilized (PC malfunction, etc.) This procedure allows the service technician to make minor adjustments and verify the proper operation of the station receive circuitry, including:
Receiver Module Power Supply Module 2.1 MHz Reference Oscillator Circuitry Receiver-related circuitry in the Station Control Module (SCM) In general, the receiver circuitry is exercised by injecting and measuring signals using a Motorola R2001 Communications Analyzer (or equivalent). Measured values outside the acceptable range indicate a faulty module; values within range verify proper operation of the above listed modules and circuitry. Required Test Equipment The following test equipment is required to perform the procedure:
Motorola R2001 Communications Analyzer (or equivalent) Telephone-style handset with PTT switch (TMN6164, or equivalent) RJ-11 to BNC cable Dummy Load (50, station wattage or higher) 9-14 68P81093C75-A IMPORTANT!
If the station operates as a repeater, the transmit output from the station must be connected to a dummy load to prevent over-the-air broadcast during receiver testing. Verifying Receiver Circuitry Procedure Step 1. Connect test equipment by performing Step 1 through 3 shown in Figure 5. NOTE: The cover plate over the SCM side of the chassis must be removed to perform these tests. Step 2. Disable PL and carrier squelch by repeatedly pressing the PL/CSQ/Off button until receiver noise is heard through the handset (or external speaker). Refer to Figure 3 for the location of the PL/CSQ/Off button. If no audio is heard, suspect the following:
Faulty Receiver Module Faulty Station Control Module R2001 is outputting a carrier signal Step 3. Set R2001 to generate a 0.5 V (-13 dBm) FM signal at the PDR 3500 receiver frequency, modulated by a 1 kHz tone at 3 kHz deviation. The 1 kHz tone should be audible through the handset (or external speaker). If no audio is heard, suspect the following:
Faulty Station Control Module (2.1 MHz reference) Faulty Receiver Module Faulty antenna-to-Receiver preselector RF cable Faulty R2001-to-station RF cable Duplexer/station receive frequency mismatch, or faulty duplexer 68P81093C75-A 9-15 1 Disconnect cables from top panel transmit and receive ports.

Audio level should measure approximately 0.75 to 1.5 V p-p. If not, suspect faulty SCM. Step 6. Change R2001 injection signal to VHF: 0.25 V (-119 dBm) UHF: 0.35 V (-116 dBm) 800 MHz: 0.30 V (-117.5 dBm). Step 7. Measure the receiver 12 dB SINAD sensitivity. The value should read 12 dB, or greater. If not, tune the preselector (VHF and UHF only) and re-check 12 dB SINAD. If 12 dB SINAD cannot be achieved, suspect the following:
Damaged cable from top panel receive port to preselector Faulty receiver Excessive loss in the R2001-to-station RF cable NOTE: To measure 12 dB SINAD, the station must be programmed for mixed mode Analog/Digital operation. Incorrect reading will result if programmed for Digital Only operation. NOTE: For VHF and UHF stations only, refer to 5. Preselector Field Tuning Procedure in this section. Procedures for tuning the receiver preselector are described. Step 8. If the station is congured with a duplexer, continue with Step 9 to test the duplexers performance. If the station is not congured with a duplexer, go to Step 16. Step 9. Steps 9 through 13 describe a method of measuring the effect of insertion loss from the duplexer on receiver sensitivity. Connect the dummy load to the stations top panel receive port through a capacitive coupler (isolated T). Connect the R2001 to the isolated side of the coupler.

Disable the transmitter by holding the Shift button and then pressing the Access Disable button on the Station Control Module, as shown in Figure 7. When the transmitter is disabled, the yellow Access disable light on the SCM will ash. This step is very important. With the transmitter disabled, the PA Full LED on the Exciter Module should not light, even when the station is receiving. 9-18 68P81093C75-A Station Control Module 1 Press and hold Shift Button. 3 Intcm/Acc D LED should Flash yellow. 2 Press Vol Down/

This level will serve as a baseline for the receiver sensitivity. If 12 dB SINAD cannot be achieved, suspect the following:
Test conguration used does not match that shown in Figure 6B. Excessive loss in the coaxial cables or coupler. Step 12. Remove the cable connecting the coupler to the top panel receive port. Connect the coupler to the duplexers antenna port. Connect the duplexers receive port to the stations top panel receive port, as in normal station operation. (See Figure 6B.) Step 13. Measure the 12 dB SINAD once again, and note the result. The difference between this 12 dB SINAD level and the level measured in Step 11 reects the insertion loss of the duplexer. The difference should be no greater than approximately VHF: 1.3 dB UHF: 1.6 dB 800 MHz: 1.5 dB If the difference is greater, suspect the following:
Duplexer receive and transmit ports are reversed Loose or damaged cables between the duplexer and the station 68P81093C75-A 9-19 Station receive frequency does not match the duplexer receive frequency. Use a different frequency or replace the duplexer. (Field tuning of duplexers is not recommended.) Step 14. Steps 14 and 15 will test the effect of duplexer quieting on receive sensitivity. Re-enable the transmitter by holding down the Shift button again and pressing the Access Disable button on the SCM. The following lights should indicate that the station is now operating as a repeater:
Yellow Access Disable light stops ashing PA Full LED on the Exciter Module lights when the station is receiving. Step 15. Test the 12 dB SINAD sensitivity. Depending on the duplexer frequency spacing, this level should be no more than 1 to 2 dB greater than the Step 13 reading
(with the transmitter disabled). If the reading is greater than 1 to 2 dB, the station and duplexer transmit frequencies do not match. Use a different frequency or replace the duplexer. (Field tuning of duplexers is not recommended.) Step 16. If the station is not digital-capable, the Verifying Receiver Circuitry test procedure is complete. The receiver circuitry is considered to be operating properly if all displays and measurements are correct. 1. Remove the test equipment. 2. Restore the station to normal service. 3. Return to the troubleshooting ow chart to resume the troubleshooting sequence. If the station is digital-capable, continue with the Digital Only portion of the Verifying Receiver Circuitry test procedure. Introduction While most module faults can be detected by running the station diagnostics provided by the RSS, the following procedure provides a more traditional method of troubleshooting the receiver circuitry. This procedure allows the service technician to make minor adjustments and verify the proper operation of the station receive circuitry, including:
Receiver Module Verifying Receiver Circuitry (Digital-
Capable Stations) 9-20 68P81093C75-A Power Supply Module 2.1 MHz Reference Oscillator Circuitry Receiver-related circuitry in the Station Control Module (SCM) The transmitter circuitry is exercised by injecting and measuring signals using a Motorola R2670 Communications Analyzer (or equivalent), and analyzing the Bit Error Rate using the RSS. Measured values outside the acceptable range indicate a faulty module; values within range verify proper operation of the above modules and circuitry. Required Test Equipment The following test equipment is required to perform the procedure:
Motorola R2670 Communications Analyzer with ASTRO CAI Option (or equivalent) PC running Radio Service Software (RSS) program Female N-type to Female N-type coaxial cable Dummy Load (50, station wattage or higher). Required for repeater stations only. IMPORTANT!
If the station operates as a repeater, the transmit output from the station must be connected to a dummy load to prevent over-
the-air broadcast during receiver testing. Step 1. Proceed to ASTRO Bit Error Rate Report (located in Chapter 4 of the RSS Users Guide, part number 68P81085E35). Follow the instructions for setting up the test equipment and initiating a BER report using the RSS. Step 2. If the BER reading is above 5%, suspect the following:
Faulty Station Control Module (2.1 MHz reference) Faulty Receiver Module Faulty top panel-to-preselector RF cable Faulty R2670-to-station RF cable Step 3. If you are injecting RF directly into the top panel receiver port, change the R2670 injection signal level to:
VHF: 0.25 V (-119 dBm) 68P81093C75-A 9-21 UHF: 0.35 V (-116 dBm) 800 MHz: 0.30 V (-117.5 dBm) If you are injecting RF through a duplexer, change the R2670 injection signal level to:
VHF: 0.29 V (-117.7 dBm) UHF: 0.43 V (-114.4 dBm) 800 MHz: 0.35 V (-116 dBm) Step 4. Note the receiver BER reading. The BER reading should be 5% or less. If not, and if a duplexer is being used, repeat the BER test, bypassing the duplexer. If the BER is 5% or less after bypassing the duplexer, the station frequencies do not match the duplexer frequencies, or the duplexer-to-top panel cables are faulty. If the BER, as tested straight into the top panel, is greater than 5%, tune the preselector and re-check the BER reading. If a reading of 5%, or less, cannot be achieved, replace the Receiver Module. NOTE: For VHF and UHF stations only, refer to 5. Preselector Field Tuning Procedure in this section, for procedures to tune the receiver preselector. Step 5. This completes the Verifying Receiver Circuitry test procedure. If all displays and measurements are correct, the receiver circuitry may be considered to be operating properly. 1. Remove test equipment. 2. Restore the station to normal service. 3. Return to the trouble shooting ow chart to resume the troubleshooting sequence. Please refer to Figure 10 for a conceptual line drawing of the motherboard, modules, and other components set at outside of the chassis and properly interconnected.

The following procedures provide instructions for replacing each of the station modules and performing any required post-replacement adjustments or programming.
WARNING: When wearing a Conductive Wrist Strap, be careful near sources of high voltage. The good ground provided by the wrist strap will also increase the danger of lethal shock from accidentally touching high voltage sources. Anti-Static Precaution The station circuitry contains many C-MOS and other static-
sensitive devices. When servicing the equipment, you must take precautionary steps to prevent damage to the modules from static discharge. Complete information on prevention of static protection is provided in Motorola publication number 68P81106E84, available through the Accessories and Aftermarket Division. Some additional precautions are as follows:
A wrist strap (Motorola part number RSX4015A, or equivalent) should be worn while servicing the equipment to minimize static buildup. CAUTION: DO NOT insert or remove station modules with power applied. This may result in damage to the modules.
Care of Gold-Plated Connector Contacts Do not insert or remove modules with power applied. Always turn off the station by unplugging the AC and DC cords from the top panel before inserting or removing modules. All spare modules should be kept in a conductive bag for storage and transporting. When shipping modules to the repair depot, always pack them in conductive material. The connectors between the modules and the station backplane board are made with gold-plated card edge connector contacts to provide maximum reliability. Gold-plated materials do not form a non-conductive oxide layer and therefore should not require cleaning under normal conditions. When the modules have been subjected to many extraction/insertion cycles, or if the station is operated in a dusty environment, the contacts may require cleaning. Do not use an eraser or any type of abrasive substance to clean either the module card edge connectors or the backplane connector contacts. 68P81093C75-A 9-25 Power Down Station Before Removing/
Inserting Modules Validating Repairs If the cleaning of gold-plated contacts is required, use a soft cloth dampened with alcohol to lightly wipe the contacts. Be sure not to touch the contact surfaces with your ngers; nger oils and salts can contaminate the contact surfaces. Before removing or inserting a module into the station chassis and engaging the backplane connector, be sure to turn off the station power by unplugging the AC or DC power cord, or both. After replacing a faulty module with a module that is known to be in good condition, perform the following tests to validate the repair. If the faulty module was detected as the result of running station diagnostics via the RSS, run the diagnostics again after the repair is made to ensure that the replacement module passes all diagnostic tests. If the faulty module was detected by an operational failure, perform the operation to ensure that the repair corrected the reported or detected failure. Module Replacement This section discusses the replacement of each of the PDR 3500s modules and related requirements and considerations. Station Control Before Removing the Old Station Control Module A new SCM contains settings in a codeplug (EEPROM). Those settings can be congured, using the RSS, after the module has been installed. If the old SCM is capable of communicating with the RSS, the old codeplug can be read from the SCM and saved to disk to be programmed into the new SCM. This is described in the Setup and Connections section of this manual, and in the RSS Users Guide
(68P81085E35). If the old SCM is incapable of communicating with the RSS, an archival codeplug (one saved on disk) can be used to program the new SCM. If an archival codeplug is unavailable, the new codeplug will have to be manually congured after installation. Physical Replacement of the Station Control Module 1. Turn off the stations power by unplugging the AC and DC power cords from the top panel. 2. Remove the 8 Phillips screws from the edges of the stations top panel and lift the chassis out of the case. 9-26 68P81093C75-A 3. Remove the cover plate on the left end of the front of the station by removing the two screws from the front of the plate, then removing the four Phillips screws from the side and bottom edges of the plate. 4. Pull out the old Control Module by gripping behind its DB-9, RJ-11, and RJ-45 connectors, distributing pressure equally among the connectors. 5. 6. Insert the new module. Make sure it is in the cardguides; push it rmly into the chassis until it seats into the card-edge connectors on the backplane. (Do not slam the board against the backplane or push any harder than necessary to seat the connectors.) If desired, power up the station while it is still out of the case to make sure the module is securely in place. If the LEDs do not light, are dim, or ash rapidly, one or more modules are not seated properly. Unplug the station before continuing to the next step. 7. Reassemble the station by reversing Steps 2 and 3. After Installing the New Station Control Module 1. If the codeplug from the old SCM was saved to disk, or if an archival codeplug exists on disk, it should be programmed into the new SCM. If no preexisting codeplug is available, the new codeplug must be congured manually using the RSS. See the Setup and Connections section of this manual or the RSS Users Guide
(68P81085E35) for details. 2. Perform the following alignment procedures as described in the RSS Users Guide (68P81085E35) or the Setup and Connections section of this manual, or both.

Remove the eight Phillips screws from the edges of the stations top panel and lift the chassis out of the case. 3. Remove the cover plate on the left end of the front of the station by removing the two screws from the front of the plate, then removing the four Phillips screws from the side and bottom edges of the plate. 4. Pull out the old Wireline Module by gripping its front, right corner (where there are no parts on the board). 5. Set all jumpers on the replacement board to match those on the faulty board. These include the following:
Input/ouput impedance matching jumpers Two-wire/four-wire select jumper DC remote control selection jumpers 6. 7. Insert the new module. Make sure it is in the cardguides; push it rmly into the chassis until it seats into the card-edge connectors on the backplane. (Do not slam the board against the backplane or push any harder than necessary to seat the connectors.) If desired, power up the station while it is still out of the case to make sure the module is securely in place. The LEDs on the Wireline should blink rapidly, indicating that rmware is transferring from the SCM to the Wireline Module. When the blinking stops, the transfer is complete. If any of the LEDs do not light or are dim, one or more of the modules are not seated properly. Unplug the station before continuing to the next step. 8. Reassemble the station by reversing Steps 2 and 3. After Installing the New Wireline Module Perform the following alignment procedures as described in the RSS Users Guide (part number 68P81085E35):

Unplug the faulty ASTRO Modem Card or the V.24 Interface Card from the Wireline board by pressing the mounting posts through the back of the board. Install the replacement card by pressing it onto the Wireline board and locking all mounting posts and connectors. 3. Re-install the Wireline Module as described above. After Installing the New Card No alignments or adjustments are required. The card is congured by the Station Control Module on power-up. Receiver Physical Replacement of the Receiver Module 1. Turn off the stations power by unplugging the AC and DC power cords from the top panel. 2. Remove the eight Phillips screws from the edges of the stations top panel and lift the chassis out of the case. 3. Remove the cover plate on the left end of the front of the station by removing the two screws from the front of the plate, then removing the four Phillips screws from the side and bottom edges of the plate. In VHF and UHF stations only, remove two more Phillips screws from the bottom of the chassis under the preselector. 4. A coaxial cable runs from a mini-UHF connector at the front of the receiver, through the center wall of the chassis, and to the top panel UHF connector. Disconnect the cable from the receiver and push the loose end of the cable through the center wall so that it is completely clear of the receiver. 5. If the station is 800 MHz, pull the receiver mounting plate from its position on top of the receiver out of the chassis. 6. Pull the old receiver out by gripping the tabs protruding past each end of the preselector for VHF and UHF stations, or by gripping the mini-UHF connector for 800 MHz stations. 7. Insert the new module. Make sure it sits at against the bottom of the chassis. Push it rmly into the chassis until it seats into the card-edge connector on the backplane. (Do not slam the board against the backplane or push any harder than necessary to seat the connectors.) 68P81093C75-A 9-29 8. Reinsert the receiver mounting plate and reattach the receiver coaxial cable by reversing Steps 4 and 5. 9. If desired, power up the station while it is still out of the case to make sure the module is securely in place. If any of the LEDs do not light, are dim, or ash rapidly, one or more of the modules are not seated properly. 10. For VHF and UHF stations, tune the preselector using the procedure in the Maintenance subsection, Preselector Field Tuning Procedure. Before continuing to the next step, be sure to unplug the station. 11. Reassemble the station by reversing Steps 2 and 3. After Installing the New Receiver Module Perform the following alignment procedures as described in the RSS Users Guide (part number 68P81085E35), or in the RSS section of this manual, or in both:
Squelch Adjust RSSI Calibrate Preselector tuning is required for proper performance of the Receiver Module and it should have been performed when installing the module, as described under Physical Replacement of the Receiver Module. If the tuning was not performed when the module was installed, perform it now. When replacing the Exciter Module, it is important to remember the frequency-sensitive nature of the Exciter/Power Amplier combination. The Exciter and the PA must match according to the model breakdown table in this manual. If an Exciter with a new frequency band is being installed, the corresponding PA must be installed, as described in the Power Amplier subsection of Module Replacement. Exciter Frequency Band Considerations Physical Replacement of the Exciter Module 1. Turn off the stations power by unplugging the AC and DC power cords from the top panel. 2. Remove the eight Phillips screws from the edges of the stations top panel and lift the chassis out of the case. 3. Disconnect the coaxial cable running to a mini-UHF connector at the front of the Exciter. For 800 MHz stations, also unplug the SMB connector at the left end of the IPA (output to the PA) and the 3-pin connector at the rear of the IPA module. If there is not enough room to disconnect this cable, it may alternatively be disconnected in the next step when the Exciter mounting plate has been partially extracted from the chassis. 9-30 68P81093C75-A 4. Tilt the chassis up on its back edge; then, from the bottom of the chassis, remove the six Phillips screws holding the Exciters mounting plate. Slide the mounting plate out of the front of the chassis. 5. Pull out the old Exciter Module by gripping behind the mini-
UHF connector and pulling gently. 6. 7. Insert the new module. Make sure it is at on the bottom of the chassis. Push it rmly into the chassis until it seats into the card-
edge connectors on the backplane. (Do not slam the board against the backplane or push any harder than necessary to seat the connectors.) If desired, power up the station while it is still out of the case to make sure the module is securely in place. If the LEDs do not light, are dim, or ash rapidly, one or more modules are not seated properly. Unplug the station before continuing to the next step. 8. Reassemble the station by reversing Steps 2 through 4. After Installing the New Exciter Module Perform the following alignment procedures as described in the RSS Users Guide (part number 68P81085E35):
Tx Deviation Gain Adjust Reference Modulation For ASTRO Simulcast systems only:
ASTRO/Simulcast Launch Time Offset Intermediate Power Amplier (800 MHz Stations only) Physical Replacement of the IPA 1. Turn off the stations power by unplugging the AC and DC power cords from the top panel. 2. Remove the eight Phillips screws form the edges of the stations top panel and lift the chassis out of the case. 3. Tilt the chassis up on its back edge; then, from the bottom of the chassis, remove the six Phillips screws holding the Exciters mounting plate. 4. Disconnect the coaxial cables running to each end of the IPA module. Also disconnect the 3-pin connector at the rear of the IPA module. The Exciter mounting plate may need to be partially extracted from the chassis in order to remove the cables. 68P81093C75-A 9-31 5. Slide the Exciter mounting plate out of the chassis with the IPA module still attached. 6. Remove four Phillips screws from the corners of the IPA module, and lift the module off of the Exciter mounting plate. 7. Set the new IPA module in place on the plate, making sure the 3-pin header is towards the rear of the station. 8. Slide the Exciter mounting plate back into the chassis, reattaching the 3 cables removed in Step 4. 9. At this point, the station may be powered up while it is still out of the case to make sure the new IPA module is functioning properly. Unplug the station before continuing to the next step. 10. Reassemble the station by reversing Steps 2 and 3. After Installing the New IPA Module Perform the following alignment procedures as described in the Setup and Connections section of this manual:
Power Output Power Amplier Frequency Band Considerations When replacing the Power Amplier, it is important to remember the frequency-sensitive nature of the Exciter/Power Amplier combination. The Exciter and the PA must match according to the model breakdown table in this manual. If a PA with a new frequency band is being installed, the corresponding Exciter must be installed, as described in the Exciter subsection of Module Replacement. Of equal importance, the PDR 3500 motherboard contains circuitry which translates between the Exciter from the original Quantar and the PA from the Spectra mobile radio. Since the translations depend upon the frequency band of the Exciter and the PA, this circuitry is also frequency-sensitive. The DIP switches on the motherboard must be set according to the frequency of the station in order for the proper translation path to be selected. The DIP switch settings can remain intact if The band of the new PA matches the one being replaced, and The Exciter is not being changed. If the PA band or the Exciter band is being changed, the DIP switches must be congured to match the new frequency of the PA and Exciter. Detach the motherboard from the chassis and set the switches as described in the Backplane subsection of Module Replacement. 9-32 68P81093C75-A Physical Replacement of the Power Amplier 1. Turn off the stations power by unplugging the AC and DC power cords from the top panel. 2. Remove the eight Phillips screws from the edges of the stations top panel and lift the chassis out of the case. 3. Remove the backplane as described in the Backplane replacement subsection, but disengage only the PA ribbon cable connector (P10) and the red and black power leads (two tab connectors closest to the bottom edge of the backplane). All other cables can remain connected. 4. Remove the four Phillips screws from the front, right quadrant of the top panel to release the PA. When removing the fourth screw, support the PA inside the chassis to prevent it from falling. 5. Disconnect all four cables between the PA and the station:
a. Unplug the red and black power cable from the PA. b. Unscrew the mini-UHF connector from the PA. c. To remove the PA ribbon cable connector, remove the two Torx screws holding the metal clip over the connector. Pull the connector loose from the PA. d. For VHF and UHF stations, unscrew the mini-UHF connector on the remaining cable from the front of the Exciter. For 800 MHz stations, unplug the SMB connector on the cable going to the left end of the IPA module. To access the connector, it may be necessary to partially slide out the Exciter mounting plate as described in the Intermediate PA replacement subsection. 6. Reconnect all four cables removed in Step 4. The ribbon cable connector is keyed so it cannot be attached incorrectly. Remember to reattach the metal clip over the ribbon cable connector. 7. Take the sheet of black thermal conductive lm that was between the old PA and the chassis and place it on the new PA. 8. Place the PA in the chassis and line up the screw holes in the PA and the thermal lm with the holes in the top panel of the chassis. (It may be useful to insert a pencil, pen, or small screwdriver through the screw holes in the top panel to aid in aligning the holes in the conductive lm with those in the PA.) 9. While holding the PA with one hand, start two or more Phillips screws in the top panel to hold the PA in place. Insert the remaining screws and tighten all four. 68P81093C75-A 9-33 10. Reconnect the PA ribbon and power cables to the backplane, making sure the ribbon connector latches securely. Make sure all other cables are attached and reattach the backplane as described in the Backplane replacement subsection. 11. If desired, power up the station while it is still out of the case to verify the PA is connected properly. Unplug the station before continuing to the next step. 12. Place the chassis back in the case and secure it with the eight Phillips screws around the top panel. After Installing the New Power Amplier Perform the following alignment procedures as described in the Setup and Connections section of this manual:

Remove the four Phillips screws holding the Power Supply to the top panel of the chassis. 4. Disconnect all ve wires from the Power Supply, then pull the Power Supply out of the chassis. NOTE: To access the wires, it may be necessary to remove either the PA or Exciter module as described in the respective Module Replacement subsection. 5. Reconnect the wires to the new Power Supply as follows:
Green to GND Orange to the H INPUT Brown to the N INPUT White to the POS OUTPUT Black to the NEG OUTPUT. 6. While holding the PS with one hand, start two or more Phillips screws in the top panel to hold the Power Supply in place. Insert the remaining screws and tighten all four. 7. Finish reassembling the station as described in Steps 11 through 18 of the Backplane subsection of Module Replacement. 9-34 68P81093C75-A Backplane Before Installing the New Backplane The PDR 3500 motherboard contains circuitry which translates between the Exciter from the original Quantar and the PA from the Spectra mobile radio. Since the translations depend upon the frequency band of the Exciter and the PA, this circuitry is also frequency-sensitive. For the proper translation path to be selected, the DIP switches located on the motherboard must be set based on the frequency band of the station. Before installing the new Backplane, set its DIP switches according to Table 12. Table 12.

Ensure the wires from the backplane do not bind against the Power Supply or Exciter modules. Slide the top of the board toward the chassis top panel, making sure the two RJ-45 connectors t into their cutouts in the top panel, and push the backplane at against the back of the chassis. 13. Start the six Phillips screws with lock washers to hold the backplane in place, but do not tighten them. 14. While applying opposing pressure to the backplane on the back of the chassis, push the Receiver, Exciter, Station Control, and Wireline (if applicable) modules back into the chassis until they snap into the card edge connectors on the backplane. (Do not slam the modules against the backplane or push any harder than necessary to seat the connectors.) 15. Reattach any cables which were removed from the Receiver, Exciter, or IPA. 16. Tighten the six Phillips screws holding the backplane to the chassis. 17. At this point, the station may be powered up while it is still out of the case to make sure the new backplane is correctly attached and functioning properly. If any of the LEDs do not light, are dim, or ash rapidly, one or more of the modules are not seated properly. Unplug the station before continuing to the next step. 18. Reassemble the station by reversing Steps 2 through 4. 9-36 68P81093C75-A After Installing the New Backplane Perform the following alignment procedures as described in the Setup and Connections section of this manual:
Power Output Using the RSS, run a complete battery of diagnostics to exercise all boards and modules. Preselector Field Tuning Procedure The VHF and UHF Receiver Modules comprise a circuit board and a preselector assembly. Both are secured in a slide-in module housing. The preselector assembly is a 3-pole (UHF) or a 5-pole (VHF) bandpass lter, equipped with tuning slugs to adjust the passband corresponding to the operating frequencies of the station. The preselector assembly must be eld-tuned if replaced in the eld, or if the station operating frequency (or frequencies) is (are) modied. The tuning procedure follows. Tuning for best SINAD response DOES NOT result in optimum tuning of the preselector assembly. You must use this eld-
tuning procedure to obtain optimum preselector performance. IMPORTANT!
Required Test Equipment The following test equipment is required to properly tune the preselector assembly:
RF Signal Generator: Motorola R2600 Communications Analyzer, R2001 Communications Analyzer (see note), or HP8656A signal generator (or equivalent) Dip/Peak Monitor: HP435B Power Meter (or equivalent) with HP8484A sensitive power head, Boonton Model 92E with BNC input, or R2001/R2600, using the spectrum analyzer function. Torque Driver, capable of delivering 12 in. lb. of torque, and 10 mm deep well socket. Tuning probe: Motorola Part number 0180763D22, part of TRN7799A tuning kit. Flat-blade screwdriver NOTE: The R2600 Communications Analyzer can both generate and measure simultaneously. The R2001 may be used for either the generator or monitor function, but not both simultaneously. When using the R2001 as a signal generator, RF signal must be taken from the antenna port. 68P81093C75-A 9-37 VHF Tuning Procedure Calculating Proper Alignment Frequency Use one of the following two methods to calculate the alignment frequency to be generated by the signal generator. For stations with a single receive frequency, calculate the frequency of the alignment signal as follows:
Step 1. From the site documentation or the RSS, determine the station receive frequency. Step 2. If the frequency is 148 MHz (Range 1) or 156 MHz (Range 2), subtract 250 kHz. Otherwise, note the actual frequency. Example: If the station receive frequency is 134.575 MHz (Range 2), subtract 250 kHz, since the frequency is less than 143 MHz. 134.575 MHz - 250 MHz = 134.325 MHz Step 3. If Receiver Module is Range 1, determine the alignment frequency as follows:
If the frequency (from Step 2) is < 134 MHz, then the alignment frequency = 133.75 MHz. If the frequency (from Step 2) is > 152 MHz, then the alignment frequency = 152 MHz. Otherwise, use the actual frequency from Step 2. Step 4. If the Receiver Module is Range 2, determine the alignment frequency as follows:
If the frequency (from Step 2) is < 152 MHz, then the alignment frequency = 151.75 MHz. If the frequency (from Step 2) is > 172 MHz, then the alignment frequency = 172 MHz. Otherwise, use the actual frequency from Step 2. For stations with multiple receive frequencies, calculate the frequencies of the alignment signal as follows:
Step 1. From the site documentation, or the RSS, note the receive frequency for each channel supported by the station. 9-38 68P81093C75-A Step 2. Calculate a midpoint frequency as follows:
Fmid = (Fhighest + Flowest) 2 Step 3. Using Fmid in place of the station receive frequency, perform Step 2 through Step 4 above. Preparing Equipment Step 1. Make sure the Receiver Module (with the Preselector Assembly) is installed in a functional PDR 3500. Step 2. Remove the chassis from its case by removing the eight Phillips screws from the edges of the stations top panel. Step 3. Remove the two Torx screws from the Receiver Module front panel and remove the four Phillips screws. Remove the panel. Step 4. De-tune the preselector as follows:
If the alignment frequency (calculated in the previous section) is greater than 148 MHz (Range 1), or greater than 156 MHz (Range 2), turn the ve tuning screws in (clockwise) until 1/8" protrudes past each of the tension nuts. If the alignment frequency is less than, or equal to 148 MHz (Range 1), or 156 MHz (Range 2), back out
(counterclockwise) the ve tuning screws until 3/4"
protrudes past each of the tension nuts. Step 5. Using the torque driver and deep-well socket, tighten the ve tension nuts on the adjustment screws to 6 in. lb. Step 6.

Otherwise, use the actual frequency from Step 1. Step 3. If Receiver Module is Range 2, determine the alignment frequency as follows:
If the frequency (from Step 1) is > 468 MHz, then the alignment frequency = 468 MHz. If the frequency (from Step 1) is < 452 MHz, then the alignment frequency = 452 MHz. Otherwise, use the actual frequency from Step 1. 68P81093C75-A 9-41 Step 4. If the Receiver Module is Range 3, determine the alignment frequency as follows:
If the frequency (from Step 1) is > 492 MHz, then the alignment frequency = 492 MHz. If the frequency (from Step 1) is < 472 MHz, then the alignment frequency = 472 MHz. Otherwise, use the actual frequency from Step 1. Step 5. If the Receiver Module is Range 4, determine the alignment frequency as follows:
If the frequency (from Step 1) is > 510 MHz, then the alignment frequency = 510 MHz. If the frequency (from Step 1) is < 496 MHz, then the alignment frequency = 496 MHz. Otherwise, use the actual frequency from Step 1. For stations with multiple receive frequencies, calculate the frequencies of the alignment signal as follows:
Step 1. From the site documentation, or the RSS, note the receive frequency for each channel supported by the station. Step 2. Calculate a midpoint frequency as follows:

For a more thorough functional description of a particular module, refer to the appropriate section of the Quantar Users Guide in Figure 17 for the following functional theory of operation.
(68P81095E05). Refer to the block diagram Transmitter Circuitry Operation Introduction The Transmitter Circuitry consists of the following:
Exciter Module Operation Exciter Module Intermediate Power Amplier (IPA) Module (800 MHz stations only) Power Amplier (PA) Module These modules combine to produce the modulated, amplied RF signal. The RF signal is transmitted via the station transmit antenna. The Exciter Module is a microprocessor-controlled module, generating a modulated RF signal at the desired transmit frequency. It sends this signal to the Power Amplier for amplication or, in 800 MHz stations, to the Intermediate Power Amplier. The circuitry operates as follows:
1. The Synthesizer/Voltage-Control Oscillator (VCO) accepts frequency programming data from the Station Control Module
(SCM) via the Serial Peripheral Interface (SPI) bus and generates an RF carrier signal at the specied frequency. The modulation audio signal from the SCM modulates the carrier, resulting in a modulated RF signal at approximately +13dBm. The modulated signal is routed to the Power Amplier, or, in 800 MHz stations, to the Intermediate Power Amplier. 2. The TX Power Control Circuitry accepts an output power detect voltage from the Power Amplier and compares this signal to a reference voltage representing the desired output power. 68P81093C75-A 10-1 Intermediate Power Amplier Module Operation (800 MHz stations only) Power Amplier Module Operation Based on the comparison, a power control voltage is generated to control the output power from the PA. This feedback and control loop continually monitors the output power. It adjusts the control voltage to maintain the proper output power from the PA. The 800 MHz PDR 3500 uses a custom, 50 variable-gain Intermediate Power Amplier to boost the RF signal from the Exciter Module to the nal Power Amplier Module. The RF input to the IPA from the Exciter can vary from +13 to +16 dBm, and the IPA is factory-tuned to provide an RF output of approximately +21 dBm to the PA. input and output, The IPA contains an RF amplier IC, a voltage regulator and potentiometer used to provide a control voltage to the IC, and impedance-matching circuitry. A 3-wire cable carries +5V, ground, and PTT signals from the backplane to the IPA. The IPA is mounted on top of the Exciter bracket and is RF shielded. The PDR 3500 uses the mid-power Spectra RF power amplier (RF PA) board, housed in a heavy-duty, shielded, aluminum heat sink. The gain of the RF PA board is controlled by the power control voltage from the Exciter Module. The modulated RF signal from the Exciter or IPA (in 800 MHz stations) is amplied by the RF PA and sent to the site transmit antenna. The transmit path inside the RF PA contains a directional coupler
(calibrated at setup), which feeds a DC voltage (proportional to the output power) to the TX Power Control Circuitry in the Exciter Module. This signal serves as the feedback signal in the power control loop. Receiver Circuitry Introduction The Receiver Circuitry performs the following functions:
Receiver Module Operation Accepts receive RF signals from the site receive antenna Filters and dual conversion Outputs a digitized receive signal to the Station Control Module. The receive signal is generated from the site receive antenna to a multi-pole, preselector lter which provides highly selective bandpass ltering. In VHF and UHF stations, the preselector is tunable and is mounted to the front of the main Receiver module. In 800 MHz stations, the preselector is xed and is internal to the Receiver. 10-2 68P81093C75-A Station Control Module Introduction Station Control Module Operation The ltered signal is then amplied and fed to the RF input of the 1st mixer. The 1st mixer combines the ltered signal with an injection signal generated by the Synthesizer/VCO. This results in a 21.45 MHz
(VHF), or 73.35 MHz (UHF and 800 MHz) 1st IF (intermediate frequency) signal. VHF and UHF receivers use high-side injection;
800 MHz receivers use low-side injection. (The injection signal is determined by frequency programming data from the Station Control Module via the SPI bus.) The 21.45 or 73.35 MHz 1st IF is ltered and routed to a custom receiver IC. This component contains the following circuitry:
2nd injection and mixing Amplication A/D (analog to digital) conversion This results in a digitized receive signal. This signal is routed to the Station Control Module as differential data. The Station Control Module (SCM) is the microprocessor-based controller for the station. Major components include the following:
MC68360 microprocessor, 56002 Digital Signal Processor (DSP) Two Application Specic Integrated Circuit (ASIC) devices
(host and DSP). The Host Microprocessor (P) serves as the controller for the SCM, operating from the station software stored in FLASH memory. This software determines the system capabilities of the station (analog,
, ASTRO SECURENET
, etc.). The Host P communicates with the station modules and the SCM circuitry via address and data buses, a High-Level Data Link Control
(HDLC) bus, and a Serial Peripheral Interface (SPI) bus. External communications is accomplished using a serial port on the top panel. 68P81093C75-A 10-3 The DSP and DSP ASIC perform the necessary digital signal processing for the station audio and data signals. The DSP circuitry interfaces with the Receiver Module (receive audio), the Exciter Module (modulation signal), and the Wireline Interface Board
(wireline audio). The 2.1 MHz Reference Oscillator generates the reference signal used by the Receiver and Exciter Modules. The Wireline Interface Board (WIB) serves as the interface between the customer telephone lines and the station. In general, the WIB processes and routes all wireline audio signals between the station and the landline equipment (such as consoles, modems, etc.). Landline-to-station and station-to-landline audio signals are connected to the WIB via RJ-45 connectors on the top panel of the station. The WIB contains the following:
A microprocessor Two FLASH memory ICs (which contain the WIB operating software downloaded by the SCM) An ASIC device to process and route the various audio signals Wireline Interface Board Introduction Wireline Interface Board Operation Analog, SECURENET
, and ASTRO signals are processed as follows:
Analog signals are converted to digital signals and routed to the Station Control Module via the Time Division Multiplex (TDM) bus. and ASTRO CAI data signals are processed by an ASTRO ASTRO modem card (the daughter board is plugged into the WIB) and sent to/from the SCM via the HDLC bus. (The station operates in transparent mode only, and does not perform encryption or decryption of the ASTRO CAI signal.) ASTRO or encoded signals are processed by the ASIC, sent SECURENET to/from the microprocessor via the data bus, and sent to/from the Station Control Module microprocessor via the HDLC bus. (The station operates in transparent mode only, and does not perform encryption or decryption of the SECURENET signal.) NOTE:
The WIB is offered in the 4-wire conguration only. 10-4 68P81093C75-A Power Supply Module Operation The Power Supply Module is a switching-type power supply which accepts an AC input (85-265 VAC, 49-61 Hz) and generates the 13.8 Vdc for the station modules and the power regulation circuitry on the motherboard. The Power Supply Module is capable of 12 A continuous load and 18 A maximum load. 68P81093C75-A 10-5 Notes 10-6 68P81093C75-A Block Diagram, Schematics, Electrical Parts List, Circuit Board Detail, and Chassis Parts List 11 68P81093C75-A 11-1 11-2 68P81093C75-A Receive Antenna RF Input/Output

Control Voltage Translation: Vo = 1.38 Vi + 3.46. When the Exciter is not present, Q6 grounds the control voltage to prevent the PA from keying. When the Exciter is present, J9-73 is grounded, turning Q6 off and enabling the control voltage. Q4 and Q5 provide keyed 9.6V to the PA when PTT is detected. R61 biases Q5 to turn off at a lower gate voltage. Power Supply feedback A/D converter. Low DC voltage detection circuitry with hysteresis. With switch 4 OFF, U16 pin 8 goes low when VDC drops below 11.0V and goes back high when VDC returns to 11.36V. With switch 4 ON, the thresholds become 12.1V and 12.5V, respectively. R99 through R102 are necessary because U22 operates at 9.6V. Power Supply SPI bus address recognition. Address is 011001. Power/Tx LED driver circuit. The operational amplier acts as a comparator to detect forward voltage from the PA. If forward voltage is present, the red LED is turned on, otherwise the green LED is turned on. Circuit to OR the PTT signals from the Station Control Module and the top-panel PTT/reset switch. C107, in concert with R55, serves to debounce the switch. Forward Voltage Translation. U12, U19, and peripheral circuitry translate the Forward Voltage (Vfwd) from the PA to the Exciter. The appropriate translation circuit is selected by the positions of switches 1, 2, and 3 of S1. The equations implemented are as follows:

PDR 3500 SchematicPart I (Sheet 1 of 2) 10 11 12 These op-amps are part of the forward voltage translation. They subtract 0.6V from the forward voltage and serve as buffers. PA Identication. U11 and U17 select the PA ID resistors read by the Exciter to determine the frequency band of the PA and the backplane DIP switch settings. Do-not-place resistors are included for possible future use and should not be placed in normal applications. Temperature Voltage Translation: U13, U18, U3, and peripheral circuitry translate the Temperature Voltage (Vtemp) from the PA to the Exciter.

(500kHz) from reaching A+ and getting out of the station on AC or DC power wires. The lter is necessary for the station to meet FCC guidelines for line conducted emissions. R86 and R87 allow the lter to be bypassed if necessary in future designs, but in normal use, R86 should not be placed, and R87 should be a 0 jumper. R56 and R57 are included to provide for a unidirectional crosspatch between stations using a single RJ-45 cable. In normal use, the resistors should not be placed. W1 is a connection for Ethernet. The ground on W1 should remain isolated from chassis ground. M1 through M25 are for future addition of a MRTI connector. A+
