INTRODUCTION AND OPERATION • 1.14.7 HOME REPEATER CHANNEL Data can be modulated as in '1' and then sent over the voice path using a Blank and Burst technique. Only one 4-wire link is then needed between each repeater and the Switch. All LTR-Net mobiles have one of the Locality repeaters assigned as their "Home Repeater". This repeater handles the data and audio unless a failure causes the Status Repeater to take over.
PAGE 29
INTRODUCTION AND OPERATION 1.15 LTR-Net FEATURES 1.14.11 TELEPHONE INTERCONNECT AND DATA TRANSMISSION 1.15.1 STANDARD AND SPECIAL CALLS Mobile transceivers can be used to access the PSTN (Public Switched Telephone Network). However, this interconnect operation must be on a secondary basis to dispatch operation. An exception is when the trunked system or channel is assigned exclusively to one user. There are two types of calls with LTR-Net signaling; Standard Calls and Special Calls.
PAGE 30
INTRODUCTION AND OPERATION 1.15.5 MONITOR BUSY Unique IDs also permit individual mobile units to be called using the special calls described in the preceding section. Calls can also be made to individual transceivers using standard call Group IDs 1-239 if an ID is assigned to only one transceiver. This is used in UHF repeaters only. The Monitor Busy feature checks the receive channel frequency for activity before allowing the repeater to transmit.

INSTALLATION SECTION 2 INSTALLATION 2.1 INTRODUCTION NOTE: If the Repeater is installed in an area that exceeds these environmental conditions, the site should be equipped with air filters to remove dust and dirt that could cause the equipment to overheat. Information in this section tells how to set up the repeater for operation in an LTR-Net system. It is assumed that the repeater has been previously aligned at the factory or as described in the alignment procedure in Section 7.
PAGE 34
INSTALLATION A switch is provided for charging the battery or can be off if a separate battery charger is used. A battery temperature sensor connection is also provided. The temperature sensor cable is shown in Figure 2-2. LED indicators are provided to show Reverse Battery connection, Charger On/Off and Battery Fault.The temperature sensor is required to adjust the charging voltage over temperature. The 120V AC cord is a standard 3-wire grounded cord used with a standard AC wall outlet.

INSTALLATION 2.7 GROUNDING RF protectors are selected by calculating the maximum instantaneous voltage at the output of the combiner. Do this by using the following equation. CAUTION PROPER SITE GROUNDING AND LIGHTNING PROTECTION ARE VERY IMPORTANT TO PREVENT PERMANENT DAMAGE TO THE REPEATER. VP = 1.414 (X) (√P(50)) As in any fixed radio installation, measures should be taken to reduce the possibility of lightning damage to the Viking VX equipment.
PAGE 37
INSTALLATION • With surge protectors, ensure that ground wires go directly to ground, and not through other equipment. • Run the ground wire for RF coax protectors directly to ground. • With coax protectors, ensure maximum instantaneous voltage does not exceed the rated voltage. • Do not run ground wires parallel to any other wiring (e.g. a ground wire parallel to a telephone line), except other ground wires.

INSTALLATION 2.10 CONNECTING RECEIVE AND TRANSMIT ANTENNAS Connect the voice link to terminals 1-2 and 3-4 (see Figure 2-8 and 2-4). Receive and Transmit antenna connector locations are shown in Figure 2-7. Although each transmitter and receiver could be connected to a separate antenna, this is usually not done because of the large number of antennas required by a multiple repeater installation. Therefore, an antenna combining system is usually used.

CIRCUIT DESCRIPTION The VCO frequency of A401 is controlled by a DC voltage produced by integrating the phase detector output pulses of U401. The phase detector senses the phase and frequency of the two input signals (fV and fR) and causes the VCO control voltage to increase or decrease if they are not the same. When the frequencies are the same the VCO is "locked" on frequency. 6.25 kHz. Since the VCO is on frequency (receive frequency plus 52.

Q409 sinks current to discharge the loop filter capacitors C450/C451 thereby decreasing the VCO control line voltage. The source current from Q408, when it is on, equals the sink current from Q409, when it is on.

This forces the +15V and +5V converters to run at the same frequency and is slightly delayed from the +26.5V converter. In operation, the power MOSFETs Q116, Q118 are on for approximately one-third of the period providing current to the primary side of T107. During that time CR121 is forward conducting and charging L101.

SERVICING SECTION 8 SERVICING 8.1 INTRODUCTION 8.2 SYNTHESIZER SERVICING 8.1.1 PERIODIC CHECKS 8.2.1 INTRODUCTION This repeater should be put on a regular maintenance schedule and an accurate performance record maintained. Important checks are receiver sensitivity and transmitter frequency, modulation, and power output. It is recommended that repeater performance be checked regularly even though periodic checks are not specifically required by the FCC.
PAGE 138
SERVICING 8.2.2 TCXO MODULE Modulus Control Signal Check the signal at TCXO, pin 5. It should be 17.5 MHz for Y201 and Y401 at a level of approximately 3V P-P. If the TCXO is defective, it is not serviceable and must be replaced with a new unit as described in Section 8.1.5. 1. The frequency of the modulus control signal on TEST 1, pin 9 should be equal to the N counter output frequency (either in or out of lock). When the VCO is in lock, this frequency should be 6.25 kHz. 2.
PAGE 139
SERVICING Measure the prescaler input frequency at fin, pin 11. Then measure the output frequency at TEST 2, pin 13 and calculate the divide number. If the VCO is not locked on frequency, the divide number should still be correct. The measured frequencies may not be exactly as calculated due to counter accuracy and resolution limitations. EXAMPLE: 450.250 MHz (transmit) NOTE: The counter should be connected to a high stability reference oscillator.

SERVICING Standby Battery Jack Uses a letter to indicate the value followed by a number to indicate the multiplier. This provides a connection point for a +24V DC standby battery. Current is drawn from the battery only when the repeater enable line is on and AC has failed, or no AC is connected. A trickle charger can be jumpered in to charge the battery when AC returns. The charger jumper is removed when a separate battery charger is used (see Figure 8-4).

SERVICING 8.6.4 CHIP RESISTORS Table 8-1 CERAMIC CHIP CAP IDENTIFICATION The value of chip resistors is indicated by a number printed on the resistor. A 3-digit number is used to identify ±5% and ±10% resistors, and a 4-digit number is used to identify ±1% resistors. The 3-digit number used to identify ±5% and ±10% resistors corresponds to the last 3-digits of the E.F. Johnson part number. This number is derived as shown.
