SECTION 1 INTRODUCTION

1.1 DESCRIPTION

The Voter System is an additional feature of the Conventional Repeater System that allows receiver voting. The voter system is used in Wide-Area Systems that require simulta neous RF coverage over an area not capable of coverage by a single repeater site. The Voter System is also used to assist the RF coverage of a system using portables where a single receiver cannot c over the area, but a sin gle transmitter site is sufficient for outgoing coverage.

1.2 MAIN COMPONENTS

The Voter System consists of at least one or more of the following modules. See Figures 1-1 and 1-2 for a Local Site and Figure s 1-1 a nd 1-3 f or a Remot e Sit e and Figure 1-4 for a 5-channel voter system block diagram.

1.2.1 CONVENTIONAL VOTING RECEIVER

The CVR (Conventional Voting Receiver) is the Receiver and Interface board. The CVR decodes the condition of the squelch line, open or closed, from the receiver. In the Remote site the audio is then passed to the Voter Module. In the Local Site, the CVRs are hard wired to the Voter Module.

1.2.2 VOTER POWER SUPPLY

Each Voter Power Supply (VPS) has th e capa ci ty to handle two VSHs (see Section 8). The maximum total of VSHs is 27, divide this by 2 and the total number of VPSs needed is 14. There are two VPSs per power shelf, therefore, 7 power shelves are the maximum number per system.

This menu is used to create new files and set or change the CVR operating parameters. The filename for the CVRs in this file is shown in the lower left corner of the sc reen.

Setup Parameters

This programs the Receiver parameters and options of each CVR at a Site. The following paragraphs explain the parameters that are set by this screen (see Figure 2-7) and give a brief description of each.

NOTE: The parameters are shown in the lower left of the pop-up screen for reference.

Figure 2-7 SETUP P ARAMETERS

Repeater Number

Each CVR is programmed with a repeater number from 1-30 for reference. Number selection can be arbitrary as long as each CVR is assigned a different number.

Receiver Frequency

Each CVR is programmed with the freuqency that it is operating on.

VHF Frequency Step

Using the space bar , sel ect eit her :

5000 Hz or 6250 Hz for allowable frequency spacing.

EXAMPLE 1:

A receive frequency of 163.05 5 MHz would have

a local oscillator (LO) frequency of

163.055 MHz + 52.95 MHz = 216.005 MHz.

Divide 216005000 by 5000 = 43201.00 Divide 216005000 by 6250 = 26088.80

Since 43201 is an integer, select 5000.

EXAMPLE 2:

A receive frequency of 163.0625 MHz would

have a local oscillator (LO) frequency of

163.0625 MHz + 52.95 MHz = 216.012500 MHz.

Divide 216012500 by 6250 = 34562.00. Divide 216012500 by 5000 = 32612.50

Since 34562 is an integer, select 6250.

To eliminate the chance of incorrect synthesizer settings arising from ambiguous frequencies, make sure this se tting is correct.

3.1 RECEIVER PROGRAMMING

3.1.1 2004PGMR PROGRAMMER

When the program is loaded into the computer and executed, the menu shows the files available from the directory. The program is used to Create, Edit, Transfer and Receive the repeater and channel parameters described in Section 3.2.

I M P O R T A N T

The commands and displays r e ferred to in this Section are for the IBM PC and may differ from IBM compatible. Refer to the computer’s operating system manual for command explanations.

3.1.2 ALIGNMENT SOFTWARE

The software for the CVR programs the Interface Board to open and close the audio/data gates necessary for t he alignment selected fro m the Test-Full Rptr/Station/CVR menu. Under the menu heading Test are the alignment procedures for the Receiver, overall Full CVR (see Section 3.4) including the Interface Board (see Figure 3-1).

Refer to Section 3.3 for Alignment Procedures as shown in the program, alignment points diagrams and test setup d iagrams.

Setup Parameters

This programs the Receiver parameters and options of each CVR at a Site. The following paragraphs explain the parameters that are set by this screen (see Figure 3-7) and give a brief description of each.

NOTE: The parameters are shown in the lower left of the pop-up screen for reference.

Repeater Number

Each CVR is programmed with a repeater number from 1-30 for reference. Number selection can be arbitrary as long as each CVR is assigned a different number.

Receiver Frequency

Each CVR is programmed with the frequency that it is operating on.

Select Repeater

Select the repeater number to be programmed or edited from the pop-up menu (see Figure 3-8). Move the cursor with the arrow key s to highlight the repeater number and press Enter.

Revision/Version

The Revision/Version is dis played fo r the repea ter modules. The format for all modules is R.V. (revision.version). The MPC information also includes the software release date and the repeater serial number (see example in Figure 3-19).

Figure 3-19 REVISION/VERSION

Mode Select

The Mode Select scr ee n places the repeat er either in the norma l mode or the test mode. In the Normal mode the repeater operates as a normal repeater.

In the Test mode the repeater transmit s a test word. This test word is the Test Mode ID set up in the Setup Param eters (see Table 3-1). Whil e in the test mode the repeater is “busy”, therefore it is important to place the repeater in Normal mode when the test mode is no longer required.

SECTION 4 800 MHz RECEIVER

4.1 RECEIVER PROGRAMMING

4.1.1 2000PGMR PROGRAMMER

When the program is loaded into the computer and executed, the menu shows the files available from the directory. The program is used to Create, Edit, Transfer and Receive the repeater and channel parameters described in Section 4.2.

I M P O R T A N T

The commands and displays r e ferred to in this Section are for the IBM PC and may differ from IBM compatible. Refer to the computer’s operating system manual for command explanations.

4.1.2 ALIGNMENT SOFTWARE
