UHF (403-470MHz) Tuning Procedure 5A.2 1.0 UHF (403-470MHz) Tuning Procedure 1.1 General The recommended hardware platform is a 386 or 486 DX 33 PC (personal computer) with 8 MBytes RAM, MS-DOS™ 5.0, Windows™ 3.1, and RSS (Radio Service Software). These are required to align the radio. Refer to your RSS Installation Manual for installation and setup procedures for the required software; the user manual is accessed (and can be printed if required) via the RSS.
PAGE 14
UHF (403-470MHz) Tuning Procedure CAUTION: DO NOT switch radios in the middle of any Service procedure. Always use the Program or Cancel key to close the tuning window before disconnecting the radio. Improper exits from the Service window may leave the radio in an improperly configured state and result in seriously degraded radio or system performance.
PAGE 15
UHF (403-470MHz) Tuning Procedure 1.2 PA Bias Voltage Adjustment of the PA Bias is critical for proper radio operation. Improper adjustment will result in poor operation and may damage the PA FET device. For this reason, the PA bias must be set before the transmitter is keyed the first time. Note: For certain radio models there are two bias voltage settings. For these radios both ‘ Bias 1 Voltage ’ and ‘ Bias 2 Voltage ‘ need to be adjusted when aligning the PA Bias.
PAGE 16
UHF (403-470MHz) Tuning Procedure 1.4 Transmitter Power The radio has two power level settings, a high power level setting, and a low power level setting. IMPORTANT: To set the transmitter power for customer applications use the Per Radio window under the Edit menu and set the “Power 1” and “Power 2” powers to the desired values.

UHF (403-470MHz) Tuning Procedure Table 2-2 Reference Oscillator Alignment. 1.6 RF-Band Target All bands ±150 Hz Front-End Filter Alignment of the front-end pre-selector is normally not required on these radios. Only if the radio has poor receiver sensitivity or the pre-selector parts have been replaced the following procedure should be performed. The softpot value sets the control voltage of the pre-selector. Its value needs to be set at 7 frequencies across the frequency range.
PAGE 18
UHF (403-470MHz) Tuning Procedure 1.7 Rated Volume The rated volume softpot sets the maximum volume at normal test modulation. 1.8 1. Set test box (GTF180) meter selection switch to the “AUDIO PA” position and the speaker load switch to the “MAXAR” position. Connect an AC voltmeter to the test box meter port. 2. From the Service menu, select Rx Alignments. 3. Select Rated Volume to open the rated volume tuning window. The screen will indicate the receive test frequency to be used. 4.
PAGE 19
UHF (403-470MHz) Tuning Procedure 1.9 Transmit Modulation Balance (Compensation) Compensation alignment balances the modulation sensitivity of the VCO and reference modulation (synthesizer low frequency port) lines. Compensation algorithm is critical to the operation of signalling schemes that have very low frequency components (e.g. DPL) and could result in distorted waveforms if improperly adjusted. The compensation value needs to be set at 7 frequencies across the frequency range.
PAGE 20
UHF (403-470MHz) Tuning Procedure 7. Click the Toggle PTT button to dekey the radio. 8. Repeat steps 4 - 7 for the remaining test frequencies. 9. Click the Program button to store the softpot values. . Table 2-5 Transmitter Deviation. 1.11 Channel Spacing Deviation 12.5 kHz 2.2-2.3 kHz 20 kHz 3.4-3.6 kHz 25 kHz 4.3-4.6 kHz 5 Tone (SELECT 5) Transmit Deviation The 5 Tone (SELECT 5) Deviation Softpot is used to tune the SELECT 5 signalling deviation. Tuning is performed at one frequency.
PAGE 21
UHF (403-470MHz) Tuning Procedure 1.12 DTMF Transmit Deviation The DTMF Deviation Softpot is used to tune the DTMF deviation. Tuning is performed at one frequency. The radio generates the required tones while the tuning window is open. Values for other frequencies are calculated by the radio software. If the radio supports 20 or 25 kHz channel spacing selection, the procedure must only be performed for 25 kHz channel spacing. Values for 20 kHz channel spacing are calculated by the radio software. 1.

Overview 5A.3 1.0 Overview This section provides a detailed theory of operation for the radio and its components. The main radio is a single board design, consisting of the transmitter, receiver, and controller circuits. The main board is designed to accept one additional option board. This may provide functions such as secure voice/data or DTMF decoder. The control head is mounted directly on the front of the radio or connected via an extension cable in remote mount operation.
PAGE 26
Open Controller Regulator U0601 is used to generate the 9.3 volts required by some audio circuits, the RF circuitry and power control circuitry. Input and output capacitors (C0601-C0603 and C0604/C0605) are used to reduce high frequency noise. R0602/R0603 set the output voltage of the regulator. If the voltage at pin 1 is greater than 1.3 volts the regulator output decreases and if the voltage is less than 1.3 volts the regulator output increases.
PAGE 27
Open Controller 2.4 Emergency The emergency switch (J0400-9), when engaged, grounds the base of Q0441 and pulls the line EMERGENCY CONTROL to low via D0441. EMER IGN SENSE is pulled high by R0441. When the emergency switch is released the base of Q0441 is pulled high by R0442. This causes the collector of transistor Q0441 to go low (0.2V), thereby setting the EMER IGN SENSE line to low.
PAGE 28
Open Controller To start SBEP communication this voltage must be above 6V. This condition generates a µP interrupt via VR0102, Q0105, Q0104, Q0106 and enables the BUS+ line for communication via Q0122, Q0121. 2.8 Microprocessor Clock Synthesizer The clock source for the microprocessor system is generated by the ASFIC (U0201). Upon powerup the synthesizer U5701 (UHF) / U3701 (VHF) / U2701 (MB) generates a 2.
PAGE 29
Open Controller When the µP needs to program any of these IC’s it brings the chip select line for that IC to a logic 0 and then sends the proper data and clock signals. The amount of data sent to the various IC’s are different, for example the FRAC-N can receive up to 21 bytes (168 bits) while the DAC can receive up to 3 bytes (24 bits). After the data has been sent the chip select line is returned to a logic 1.
PAGE 30
Open Controller 2.11 General Purpose Input/Output The Controller provides one general purpose line (GP I/O) available on the accessory connector J0400-12 to interface to external options. The software and the hardware configuration of the radio model defines the function of the port. The port uses an output transistor (Q0432) controlled by µP via ASFIC port GCB3 (pin B3) and an input transistor (Q0431) read by µP port PA7 (pin 4). To use the GP as input the µP must turn off the output transistor.
PAGE 31
Open Controller The K1µP provides an address bus of 16 address lines (A0-A15), and a data bus of 8 data lines (D0D7). There are also three control lines; CSPROG (U0101-29) to chip select U0102-30 (FLASH EEPROM), CSGP2 (U0101-28) to chip select U0103-20 (SRAM) and PG7_R_W to select whether to read or to write. All other chips (ASFIC/PENDULLUM/DAC/FRACN/LCD/LED/optional EEPROM/ OPTION BOARD) are selected by 3 lines of the µP using address decoder U0105.
PAGE 32
Open Controller 2.13 FLASH Electronically Erasable Programmable Memory (FLASH EEPROM) The 256 KByte FLASH EEPROM (U0102) contains the radio operating software. This software is common to all open architecture radios within a given model type. This is, as opposed to the codeplug information stored in EEPROM (U0104) which could be different from one user to another in the same company. In normal operating mode, this memory is only read, not written to.
PAGE 33
General 2.15 Static Random Access Memory (SRAM) The SRAM (U0103) contains temporary radio calculations or parameters that can change very frequently, and which are generated and stored by the software during its normal operation. The information is lost when the radio is turned off. The device allows an unlimited number of write cycles. SRAM accesses are indicated by the CS signal U103-20 (which comes from U101-CSGP2) going low.
PAGE 34
Transmit Audio Circuits 4.0 Transmit Audio Circuits Refer to Figure 3.1 for reference for the following sections. 4.1 Mic Input Path The radio supports two distinct microphone paths known as internal (from Control Head) and external mic (from accessory connector J0400-2) and an auxiliary path (FLAT TX AUDIO). The microphones used for the radio require a DC biasing voltage provided by a resistive network.
PAGE 35
Transmit Audio Circuits 4.2 External Mic Path The external microphone signal enters the radio on accessory connector J0400 pin 2 and is routed to the ASFIC (U0201-A7) through resistor R0414, capacitor C0413 and line EXT MIC, with DC bias provided by R0415 / R0416. R0415 and C0417 provide a 1kΩ AC path to ground that sets the input impedance for the microphone and determines the gain based on the emitter resistor in the microphone’s amplifier circuit.
PAGE 36
Transmit Signalling Circuits 5.0 Transmit Signalling Circuits Refer to Figure 3.2 for reference for the following sections. From a hardware point of view, there are three types of signalling: 1. Sub-audible data (PL/DPL/Connect Tone) that gets summed with transmit voice or signalling, 2. DTMF data for telephone communication in trunked and conventional systems, and 3. Audible signalling including Select 5, MPT-1327, MDC, High speed Trunking.
PAGE 37
Transmit Signalling Circuits 5.2 High Speed Data High speed data refers to the 3600 baud data waveforms, known as Inbound Signalling Words (ISWs) used in a trunking system for high speed communication between the central controller and the radio. To generate an ISW, the µP first programs the ASFIC (U0201) to the proper filter and gain settings. It then begins strobing U0201-G1 (TRK CLK IN) with a pulse when the data is supposed to change states.

Receive Audio Circuits CH ACT is routed to the µP pin 25 (pin 40 from version 0102726B09_Cntl on) while SQ DET adds up with LOCK DET, weighted by resistors R0113, R0114, and is routed to one of the µP´s ADC inputs U0101-43. From the voltage weighted by the resistors the µP determines whether SQ DET, LOCK DET or both are active. SQ DET is used to determine all audio mute/unmute decisions except for Conventional Scan. In this case CH ACT is a pre-indicator as it occurs slightly faster than SQ DET. 6.
PAGE 40
Receive Audio Circuits The audio PA is enabled via AUDIO PA ENABLE signal from the ASFIC (U0201-B5). When the base of Q0401 is low, the transistor is off and U0401-8 is high, using pull up resistor R0406, and the Audio PA is ON. The voltage at U0401-8 must be above 8.5VDC to properly enable the device. If the voltage is between 3.3 and 6.4V, the device will be active but has its input (U0401-1/9) off. This is a mute condition which is not employed in this radio design.

PAGE 42
Receive Signalling Circuits The allowable internal alert tones are 304, 608, 911, and 1823Hz. In this case a code contained within the SPI BUS load to the ASFIC sets up the path and determines the tone frequency, and at what volume level to generate the tone. (It does not have to be related to the voice volume setting). For external alert tones, the µP can generate any tone within the 100-3000Hz audio band. This is accomplished by the µP generating a square wave which enters the ASFIC at U0201-C3.

Receiver Front-End 5A.3 UHF SPECIFIC CIRCUIT DESCRIPTION 8.0 Receiver Front-End The receiver is able to cover the UHF range from 403 to 470 MHz. It consists of four major blocks: front-end, mixer, first IF section and IF IC. Antenna signal pre-selection is performed by two varactor tuned bandpass filters. A double balanced shottky diode mixer converts the signal to the first IF at 45.1 MHz.
PAGE 44
Transmitter Power Amplifier (PA) 5-25W 8.3 IF IC (U5201) The first IF signal from the crystal filters feeds the IF IC (U5201) at pin 6. Within the IF IC the 45.1MHz first IF signal mixes with the second local oscillator (LO) at 44.645MHz to the second IF at 455 kHz. The second LO uses the external crystal Y5211. The second IF signal is amplified and filtered by two external ceramic filters (FL5201, FL5202).
PAGE 45
Transmitter Power Amplifier (PA) 5-25W 9.2 PA Stages The bipolar transistor Q5520 is driven by Q5510. To reduce the collector - emitter voltage and in turn the power dissipation of Q5510 its collector current is drawn from the antenna switch circuit. In transmit mode the base of Q5520 is slightly positive biased by a divided K9V1 signal.
PAGE 46
Transmitter Power Amplifier (PA) 5-25W A high impedance resonant circuit formed by D5551 in off state and L5554, C5559 prevents an influence of the receive signal by the PA stages. The high impedance of D5631 in off state doesn´t influence the receiver signal. 9.5 Harmonic Filter The transmitter signal from the antenna switch is channelled through the harmonic filter to the antenna connector J5501.The harmonic filter is formed by inductors L5552, L5553, and capacitors C5557,C5552 through C5555.
PAGE 47
Frequency Synthesis Loop frequency response is controlled by opamp feedback components R0712 and C0711. Opamp U0701-3 compares the power control voltage PWR CNTL divided by resistors R0717 to R0719 with the voltage limit setting VLTG LIMIT SET from the D/A converter (U0731-13) and keeps the control voltage constant via Q0711 if the control voltage, reduced by the resistive divider (R0717 to R0719), approaches the voltage of VLTG LIMIT SET (U0731-13).
PAGE 48
Frequency Synthesis 10.2 Fractional-N Synthesizer (U5701) The FRAC-N synthesizer IC (U5701) consists of a pre-scaler, a programmable loop divider, control divider logic, a phase detector, a charge pump, an A/D converter for low frequency digital modulation, a balance attenuator to balance the high frequency analogue modulation and low frequency digital modulation, a 13V positive voltage multiplier, a serial interface for control, and finally a super filter for the regulated 9.3 volts. A voltage of 9.
PAGE 49
Frequency Synthesis 10.4 Synthesizer Operation The complete synthesizer subsystem works as follows. The output signal of the VCO (Q5741) is frequency doubled by doubler D5751 and, buffered by Common VCO Buffer Q5751. To close the synthesizer loop, the collector of Q5791 is connected to the PREIN port of synthesizer U5701 (pin 20). The buffer output (Q5751) also provides signals for the Mixer Buffer Q5771 and the PA Buffer (Q5781).
