Described are the intended use of the mounting hardware and the electrical connections that should be made. 2.2.2 PERFORMANCE TESTS Although each transceiver is carefully aligned and tested at the factory, shipment can alter these settings or damage the transceiver.
Figure 2-2 Standard Remote Mount Installation Components Dual Control - The remote control unit is connected to a front-mount transceiver. This allows the transceiver to be controlled from both the transceiver front panel and the remote control unit. The displays on the transceiver and control unit indicate identical information. Dual Remote - Two remote control units are connected to a remote mount transceiver. This allows the transceiver to be mounted remotely from both control units.
2.3.2 SELECTING A MOUNTING LOCATION Front-mount transceivers are designed for mounting in a location near the operator such as the dash, console, or transmission hump. Remote-mount transceivers are designed for mounting in an out-of-the-way location such as the trunk. WARNING The mounting location of the transceiver or control unit can affect safe operation of the vehicle.
2.4 POWER CABLE INSTALLATION NOTE: As described in Section 2.1,connect the power cable directly to the vehicle battery, and to an unswitched power source so that it de-affiliates when power is turned off. 2.4.1 STANDARD MODELS Refer to Figures 2-1 or 2-2 and proceed as follows: 1. Disconnect the negative cable from the battery to prevent damage from accidental short circuits. 2. Route the red and blue power cables to the battery.
Figure 2-5 Accessory Jack 2.5.2 IGNITION SENSE INPUT (PIN 6) NOTE: As previously described, the ignition sense line must be connected to a switched or unswitched power source for the transceiver to power up. This ignition sense line is Pin 6 of the accessory connector, and it is connected using an included wire assembly. When the ignition sense input is connected to a source switched by the vehicle ignition switch, it provides the following functions. 1. 2.
Horn Alert To use the horn alert, a Horn option switch, Cadence Style, and Auxiliary B Horn output must be programmed. Refer to Section 4.7 of the operating manual (see Section 3) and the programming manual referenced in Section 4 for more information. (The Aux B output is programmed on page 2 of the Global screen.) When the horn alert sounds, Pin 4 of the accessory connector goes low. If a relay is used, a diode should be connected across the relay coil with the cathode toward the battery side.
External Emergency Switch When this function is programmed, an emergency condition can be triggered using an external emergency switch such as a foot-operating type.

SECTION 5 CIRCUIT DESCRIPTION 5.1 GENERAL TRANSCEIVER DESCRIPTION 5.1.1 INTRODUCTION The E.F. Johnson 4300 is a microcontroller-based radio that uses a Digital Signal Processor (DSP) to provide the following modes of operation: Narrowband Analog - FM modulation with a maximum deviation of 2.5 kHz. This mode is usually used in systems where the channel spacing is 12.5 kHz. Call Guard (CTCSS or DCS) subaudible squelch signaling can be used in this mode.
5.1.3 CIRCUIT PROTECTION (FUSES) Circuit protection is provided as follows: • • • An 8- or 10-ampere fuse in the power cable provides overall transceiver protection. A 2-ampere fuse on the RF board protects circuits on that board. F700 (2-ampere) on the display controller board protects the Sw B+ output of the microphone connector. • F1 on the logic board protects the Sw B+ output of universal interface connector J5.
In Project 25 Digital Mode, the carrier is modulated with four discrete deviation levels. These levels are ± 600 Hz and ± 1800 Hz. Digitized voice is created using an IMBE™ vocoder. (IMBE™ voice coding technology embodied in this product is protected by intellectual property rights including patent rights of Digital Voice Systems, Inc.) Receive Mode The signal is processed in the same way as an analog mode transmission until after the squelch function is performed.
Front End LNA and Bypass Switching The Low Noise Amplifier (LNA) is critical in determining the overall noise figure of the receiver chain. An MGA-71543 amplifier (U39) provides optimum noise figure, gain, intercept point, and power consumption. Post-LNA Bandpass Filters An additional bandpass filter is located after the LNA. This filter is identical to the front end filter previously described and provides additional image rejection.
A two-pole 64.455 MHz crystal filter (U2) is used to provide the desired level of adjacent channel rejection while providing minimal amplitude and phase distortion within a 25 KHz bandwidth. Shields are installed around the crystal filter to provide sufficient isolation to meet the second image response specifications and to minimize noise pickup by the impedance-matching inductors (L1, L2, L3, L4 and L7.
The transmit PLL phase locks a transmit oscillator that is operating at an output frequency of 138 to 174 MHz. The RF signal into the PLL chip is created by mixing the transmit frequency with the receive PLL frequency to generate a mix frequency of 374.4 MHz. This provides low frequency modulation of the VCO by modulating the transmit PLL reference frequency.
The power amplifier (U3) is a Mitsubishi RA07M1317M module. This PA module provides the desired RF power output level and is stable over a wide range of VSWR conditions. The PA is driven by a SGA-6589 driver (U20) that typically provides +21 dBm output power. The PA is turned on and off by switching the power to this driver via transistor D10. ALC To maintain the specified transmitter output power level, Automatic Level Control (ALC) is used to control the drive level to the PA.
