1 GENERAL

1.1 Introduction

The OS-3A/H Synthesizer Module produces a low distortion, high stability, FM modulated (FM

transmitter) or unmodulated (receiver LO, AM transmitter) RF signal covering the frequency bands

of 29 - 50 MHz, 118 - 159.4 MHz, 118 - 174 MHz and 406 - 470 MHz. It achieves ±1 ppm

frequency stability from -40°C to +60°C with its own internal reference, or it can be slaved to an

external 10/9.6 MHz reference signal of desired stability. The OS-3H Synthesizer Module is

provided in eleven models covering three primary frequency bands (see section 1.2). A synthesizer

module can be easily removed for programming, calibration, or repair. Each synthesizer module

contains two circuit boards providing digital and analog functionality. The analog RF circuitry is

fully isolated in a shielded compartment. Three inter-board filtered wire connections provide signal

and power interface. Digital signal and power control is provided through five photo-logic optical

transceivers, further enhancing electrical noise isolation.

1.2 OS(R/T)-3(A/H) Enhanced Synthesizer Family Models

The OS-3A/H Synthesizer module family forms an integral component of the MT-3 receiver and

transmitter product line. In transmitters, the OS-3A/H synthesizer provides a modulated low level

RF signal to the Power Amplifier module. In receivers, the OS-3A/H synthesizer provides a low

noise local oscillator signal that either directly drives the mixer circuitry or drives a buffer amplifier

in order to achieve higher LO mixer drive required for enhanced intermodulation capability. There

are eleven distinct models in the OS-3H Enhanced Synthesizer Family. Note that this manual

provides service and operating information for

all eleven synthesizer family members. It is

important to establish the correct synthesizer model number of interest in order to direct attention to

specific documented information. The specific model number is printed on the synthesizer module

top cover.

The eleven models are described as follows:

The OS-3A/H Enhanced Synthesizer models are very similar; all models use the same digital board

and mechanical construction. The significant differences between the models relate to the analog

board. There are four different analog boards covering the four frequency bands of 29 - 50 MHz,

118 - 159.4 MHz, 128 - 174 MHz and 406 - 470 MHz respectively. Each model’s specific sub

band of operation in a given frequency band is determined by select components on the

corresponding analog board.

1.4 Printed Circuit Board Numbering Convention

To ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted a

printed circuit board (PCB) numbering convention in which the last two digits of the circuit board

number represent the circuit board version. For example:

• PCB number 43-9120

10 indicates circuit board version 1.0;

• PCB number 50002-

indicates circuit board version 2.0.

All PCB's manufactured by Daniels Electronics are identified by one of the above conventions.

2 THEORY OF OPERATION

2.1 Internal Power and Control (Digital Board)

Refer to "OS(R/T)-3(A/H) Digital Board Schematic Diagram" in section 4 page 19. The

synthesizer operates from +9.5 Vdc applied to connector pin P1-2. Total current drain is

approximately 160 mA (65 ma for AM). Power Down control (P2-4) controls the +5.0 Vdc

microcontroller regulator U2 through power MOSFET switch U1. For receiver applications, the

synthesizer is always operating with the enable line P2-4 permanently connected to +9.5 Vdc. In

transmitter applications, pin P2-4 is controlled by MT-3 Transmitter Board jumper J18 which

selects the synthesizer's standby mode. In low current standby mode (< 16/4 mA) approximately

50 ms of transmitter turn on delay from PTT activation must be tolerated (lock time of

synthesizer). For transmitter applications requiring less than 10 ms of turn on delay, the

synthesizer can be made to run continuously. This capability comes at the expense of an additional

160 (65 mA for AM) of transmitter standby current.

2.2 Synthesizer Analog Circuitry (Analog Board)

There are four separate analog circuit boards covering the four frequencies bands of 29 - 50 MHz,

118 - 159.4 MHz, 128 - 174 MHz and 406 - 470 MHz respectively. All four analog boards are

similar in operation and circuit topology with the VCO, Loop Filter, and Output Lowpass Filter

sections being band specific. Refer to "OS(R/T)-3(A/H) Analog Board Schematic Diagram” in

section of this manual.

2.2.1 Common Analog Board Circuitry

This section describes the circuitry common to all versions of the FM Synthesizer Analog Board.

The Analog Board utilizes four optical receivers (U1 - U4), and one optical transmitter (U5) to

provide an isolated data interface to the digital board. In normal operating modes, +9.5 Vdc

Regulator IC U8 provides continuous +5.0 Vdc to the internal TCXO and power control optical

receiver U1. This results in a standby current level of ≈ 10 mA for FM and 4 mA for AM. Primary

power is controlled through activation of optical receiver U1 under control of the digital board

micro controller U4. Regulator U6 provides switched +8.0 Vdc with regulator U7 providing

switched +5.0 Vdc to all analog supply points. Power MOSFET IC U9 works as a clamping

circuit to quickly discharge VCO filter capacitors C32 and C33 when powered down, resulting in

immediate suppression of RF output from the VCO.

The OS-3H enhanced synthesizer is formed around a low power, single chip MC145190

(MC145191) synthesizer IC U10. A 9.6 MHz reference signal is provided from either the internal

TCXO (JU1-B Analog Board), or an external source via SMB connector J1 with jumper JU1-A

DE DANIELS

ELECTRONICS

2-2 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz

(Analog Board) and jumper JU2 (AM Analog Board only) installed. The external reference source

may be 9.6 MHz or 10.0 MHz through selection of jumper JU2 (Digital Board); install jumper

JU2 (Digital Board) for 10.0 MHz reference selection. If an external signal is used for the

reference source, it must be of low phase noise, high stability, with a level of 0 dBm ± 3 dB. A

sinusoidal signal shape is required for an external reference source. A poor quality reference

source will degrade receiver/transmitter performance to unacceptable levels. Transistor Q2 forms a

buffer amplifier having 50Ω input impedance at 10.0 MHz. The internal 9.6 MHz TCXO provides

better than 1 ppm frequency stability from -30°C to +60°C. Fine frequency adjustment is made

through frequency control potentiometer RV1, which is accessible through the synthesizer top

cover.

The 9.6 MHz reference source is divided down to establish a channel selection step size of

5.0/6.25, 12.5, or 25.0 kHz depending on the particular synthesizer model type. A third order

passive loop filter comprised of C37, C38, C39, C45, C49, R36 and R32, is employed to achieve

the required noise performance, modulation, and worst case switching time of 50 ms. A small

sample of RF energy is coupled from the VCO output buffer U16 on the FM analog board or from

Q6 on the AM analog board to the synthesizer IC U10 prescaler input (pin 11). FM modulation of

the VCO from ≈ 100 Hz to 3 kHz, is provided through the baseband input pin P1-1 on Digital

Board. A 1 kHz sine wave with a level of approximately 400 mVrms at P1-1 provides FM

deviation of 3.0 kHz. SMB connector J2 provides an RF output level of approximately +5 dBm

into a 50Ω load.

An optional modulation input is provided through connection P1-18 (Digital Board) and routed to

the Analog board via connection P3. This connection must be coupled to a low impedance, dc

coupled source and provides a phase modulated bandwidth from 0 (DC) to ≈ 50 Hz (PLL loop

filter bandwidth) allowing for specialized applications such as paging or trunking where a separate

low frequency digital/analog modulation channel is required. Phase modulation input pin P1-18 is

routed to the transmitter audio processor spare pin P4-2 via JA4-2 on the MT-3 transmitter main

board. It should be noted that any application of the direct TCXO modulation port transfers the

control of the synthesizer steady state frequency setting to the external modulating source.

Frequency control potentiometer RV1 is effectively removed from the frequency adjust circuitry.

A lock detect LED (LED1) indicates an unlocked PLL condition. An unlocked PLL condition

normally indicates that the VCO is not tuned within the lock in range of the desired channel

frequency. When used in a transmitter, the loss of lock will prevent PTT from keying the power

amplifier module. This prevents transmission of a spurious, unlocked output signal. Adjustment of

tuning capacitor C24 will normally reestablish frequency lock within the synthesizer design

frequency range. Optical transmitter U5 is additionally activated in unlocked conditions and

enables the micro-controller (digital board) to respond to the unlocked PLL state. Note that the

118 – 159.4 MHz and the 406 - 470 MHz Analog Board does not incorporate a VCO tuning

capacitor; the VCO covers the full frequency range without tuning. An unlocked condition in this

case would indicate an attempt to synthesize an invalid channel frequency outside the installed

VCO frequency range.

2.2.2 29 - 71.4 MHz Analog Board Circuitry

Refer to the "OS(R/T)-3H 29 - 71.4 MHz Analog Board Schematic Diagram" located in section 4

page 3 of this manual.

Field effect transistor Q5 provides a VHF negative resistance amplifier/oscillator that is tuned on

frequency by the combination of resonator L5 and a total capacitive reactance presented across L5

through capacitors C62, C63, C64, C23 (Select), variable capacitor C24, and varactor diodes D1

and D2. Fine frequency adjustment is provided by multi-turn trimmer capacitor C24 in conjunction

with coarse frequency jumper selections JU2, JU3, and JU4. Select capacitor values are chosen to

position the operating frequency in one of three bands; 29 - 38 MHz, 38 - 50 MHz, and 50.4 -

71.4 MHz. Varactor diodes D1 and D2 provide oscillator frequency control. PLL voltage feedback

control from the output of the lowpass loop filter controls the VCO frequency through the reverse

biasing of varactor diodes D1 and D2. The PLL control voltage can range from ≈ +1.0 Vdc to

+7.0 Vdc and is normally set to ≈ +4.5 Vdc for the nominal programmed synthesizer center

frequency. Setting the PLL control voltage set point (TP4) is made by adjusting fine frequency

variable capacitor C24 combined with binary weighted lumped capacitor coarse frequency jumpers

(JU2, JU3, JU4). External baseband frequency modulation is provided through connection P1

and a voltage divider network formed by R21 and R22. A large signal division ratio, established

by the resistive dividers R21 and R22, allows low deviation (less than 5 kHz) direct frequency

modulation of the VCO output signal.

The PLL lowpass filter is formed from select component values C37, C38, C39, C45, R32, and

R36. The loop filter response is optimized for switching time, noise, and modulation requirements

specific to each sub-band within the 29 - 71.4 MHz frequency range. The select component values

(including the loop filter) can be found in tabular format as part of the VHF OS-3H 29 - 71.4 MHz

Analog Board Schematic diagram.

RF output power is taken from the source of Q5 and amplified/buffered by U11. U15 provides

further amplification and isolation while delivering ≈ +10 dBm to a six pole lowpass/notch output

filter formed from C53, C57, C58, C59, L11, and L13. The six pole output filter provides a 50

MHz (OST-3H035, OST-3H045 TX) or 80 MHz (OSR-3H061 RX) cutoff frequency which

reduces harmonic output to acceptable levels. SMB connector J2 provides interconnection to the

companion transmitter or receiver with an output level of ≈ +5 dBm.

2.2.3 118 - 159.4 MHz Multichannel AM Analog Board Circuitry

Refer to the "OS(R/T)-3H 118 - 159.4 MHz Analog Board Schematic Diagram" located in section

4 page 7 of this manual.

Field effect transistor Q5 provides a VHF negative resistance amplifier/oscillator that is tuned on

frequency by the combination of tapped resonator L5 and a total capacitive reactance presented

across L5 through capacitors C40 and/or C23 (Select), varactor diodes D6, D7, and varactor

DE DANIELS

ELECTRONICS

diodes D1 and D2. Coarse frequency adjustment is provided by varactor diodes D6, D7. Select

capacitor values C40 or C23 are chosen to position the operating frequency in one of two bands;

118 - 138 MHz, and 139.4 - 159.4.MHz. Varactor diodes D1 and D2 provide fine oscillator

frequency control. PLL voltage feedback control from the output of the lowpass loop filter controls

the VCO frequency through the reverse biasing of diodes D1 and D2. The PLL control voltage can

range from ≈ +1.0 Vdc to +4.7 Vdc and is normally set to ≈ +3.3 Vdc for the whole range of

synthesizer frequencies. Setting the PLL control voltage set point (TP4) is made by adjusting the

capacitance of varactor diodes D6, D7, which are controlled by a microcontroller U18 through a

digital to analog converter U17. The microcontroller U18 controls the test point TP4, the output of

the PLL Low Pass Filter, and adjusts the output voltage of D/A converter so that the TP4 voltage is

approximately is 3.3Vdc at any frequencies. The microcontroller than goes sleep in order to keep

the power consumption at the low level.

The PLL lowpass filter is formed from select component values C37, C38, C39, C45, R32, and

R36. The loop filter response is optimized for switching time, noise, and modulation requirements

specific to each sub-band within the 118 - 159.4 MHz frequency range. The select component

values (including the loop filter) can be found in tabular format as part of the VHF OS(R/T)-

3(A/H) 118 - 159.4 MHz Analog Board Schematic diagram.

RF output power is taken from the source of Q5 and amplified/buffered by Q6. U11 provides

further amplification and isolation while delivering ≈ +10 dBm to a five pole lowpass output filter

formed from C53, C58, C59, L11, and L12. The five pole lowpass output filter provides a 190

MHz low pass cutoff frequency which reduces harmonic output to acceptable levels. SMB

connector J2 provides interconnection to the companion transmitter or receiver with an output level

of ≈ +5 dBm.

2.2.4 128 - 174 MHz Analog Board Circuitry

Refer to the "OS(R/T)-3(A/H) 128 - 174 MHz Analog Board Schematic Diagram" located in

RF output power is taken from the source of Q5 and amplified/buffered by U11. U15 provides

further amplification and isolation while delivering ≈ +10 dBm to a five pole lowpass output filter

formed from C53, C58, C59, L11, and L12. The five pole lowpass output filter provides

a 190 MHz low pass cutoff frequency which reduces harmonic output to acceptable levels. SMB

of ≈ +5 dBm.

2.2.5 406 - 470 MHz Analog Board Circuitry

Refer to the "OS(R/T)-3H 406 - 470 MHz Analog Board Schematic Diagram" located in section 4

page 15 of this manual.

The UHF OS(R/T)-3H 406 - 470 MHz synthesizer employs integrated surface mount VCO

modules (designated U17) for full frequency band coverage. Two VCO modules are used to cover

406 - 470 MHz (TX) and 427.4 - 451.4 MHz (RX) for transmitter and receiver UHF applications

respectively. The receiver VCO module is optimized for low phase noise, while the transmitter

VCO is configured with modulation input capability. PLL voltage feedback control from the output

of the lowpass loop filter controls the VCO frequency through Mod I/P (pin 2). The PLL control

voltage can range from ≈ +1.0 Vdc to +7.0 Vdc depending on the selected operating frequency.

External baseband frequency modulation is provided through connection P1 and VCO Mod input

pin 6.

The PLL lowpass filter is formed from select component values C37, C38, C39, C45, R32, and

R36. The loop filter response is optimized for switching time, noise, and modulation requirements

specific to each sub-band within the 406 - 470 MHz frequency range. The select component values

(including the loop filter and VCO type) can be found in tabular format as part of the UHF

OS(R/T)-3H 406 - 470 MHz Analog Board Schematic diagram.

RF output power is taken from the VCO RF output and amplified/buffered by U11. U15 provides

further amplification and isolation while delivering ≈ +10 dBm to a five pole lowpass output filter

formed from C53, C58, C59, L11, and L12. The five pole lowpass output filter provides

a 530 MHz low pass cutoff frequency which reduces harmonic output to acceptable levels. SMB

connector J2 provides interconnection to the companion transmitter or receiver with an output level

of ≈ +5 dBm.

2.3 Synthesizer Digital Circuitry (Digital Board)

Refer to the "OS(R/T)-3(A/H) Digital Board Schematic Diagram" on page 4-19. Microcontroller

U4 provides control of the synthesizer module. It communicates with synthesizer IC U10,

monitors the synthesizer lock detect, manages PTT input/output, and determines the operating

frequency from either four rotary BCD switches or four externally driven channel select lines. The

rotary BCD channel switches are located on the main MT-3 Transmitter or Receiver circuit board.

The Microcontroller U4 also communicates with an external factory programmer through I/O lines

TX DATA (P1-17), RX DATA (P1-9), and BOOTSTRAP (P2-2). The external programmer

places the operating program in non volatile microprocessor memory. It is also used to program 15

user defined channel selections. An internal "watchdog" timer provides robust software protection

in all operating modes.

Data communication between the digital and analog circuit boards is provided by four optical

transmitters (U5 through U8) and one optical receiver (U9). The optical interface provides a fully

isolated inter-board data link designed to eliminate digital noise from disturbing sensitive PLL

circuitry.

2.4 Frequency Control

2.4.1 BCD Switch Frequency Control

Selection of the desired synthesizer output frequency is straight forward. If all four of the channel

select lines CHAN SEL3 - CHAN SEL0 are pulled low (grounded), the synthesizer will scan four

BCD switches connected to SW1 COM - SW4 COM and PC4 - PC7 to establish the operating

frequency. The BCD switches are located on the receiver and transmitter main circuit boards.

* Note: The four channel select lines, CHAN SEL3 - Chan SEL0, are connected via the MT-3

transmitter or receiver main board module connector to the M3 motherboard subrack. These lines

may be used for external frequency control. They are normally pulled low via jumper sets located

on the M3 motherboard subrack.

If the channel select lines are pulled high to +9.5 Vdc in any combination resulting in a binary code

greater than 0000 (all low), then the frequency is established as the preprogrammed entry in a table

containing 15 separate frequency settings. For example; if all the channel select lines are pulled

high then a binary code of 1111 results which selects the frequency entry from the 15th table

position. CHAN SEL3 is the most significant bit of the binary channel selection code. The channel

table is normally programmed at the factory for those applications requiring specialized remote

control of frequency. These programmed channel assignments are stored in non-volatile

microprocessor EEPROM and are not susceptible to inadvertent erasure.

In transmitters, the synthesizer operating frequency is the transmitter operating frequency;

however, for receivers, an IF Offset correction factor (21.4 MHz typically) must be added to or

DEDANIELS

ELECTRONICS

Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz 2-7

subtracted from the synthesizer operating frequency in order to determine the actual receive

frequency. Refer to the channel designation table documentation provided with the transmitter or

receiver modules for simplified channel number and frequency information.

2.4.2 Frequency Select Handle Frequency Control

For operation in this mode the external channel select must be set to channel #16. Channel

selection is achieved by pushing the buttons Frequency Increase Ø and Frequency Decrease Œ on

the Frequency Select Handle. The Frequency Select Handle is located on the Front Panel. The user

interface consists of an 8 digit display and 3 pushbuttons. On power up or key press, the

synthesizer is interrogated for the current channel number and channel frequencies. This

information is used to generate the display, and update the synthesizer itself. The module

communicates with the synthesizer using a standard 2 wire serial interface (9600 Baud, 8 bits, no

parity, 1 stop bit). The command protocols are simple ASCII, both to and from the synthesizer.

The frequency value and the channel are displayed on the Front Panel for several seconds only, in

order to conserve power. Another dedicated line allows the handle to temporarily wake up the

synthesizer if it has been powered down. (This is currently only used on the transmitters)

For the detailed information about changing frequency see the "Frequency Select Handle

Instruction Manual".

2.5 Synthesizer Base and Frequency Increment Table

The OS-3A/H Synthesizer operates in frequency increments of 5.0 / 6.25 kHz, 12.5 kHz, or 25

kHz depending on the particular model and band of operation. The Base Frequency is the lowest

frequency of any given synthesizer model.

The operating frequency is determined as follows for Synthesizers having 5.0/6.25 kHz channel

increment capability;

• for BCD switch settings (in the range of 0000

4999 , multiply the switch

setting by 5.0 kHz and add it to the synthesizer base frequency.

Example: An OST-3H141 synthesizer has a base frequency of 128 MHz. The

selected channel number is 0988. The

synthesizer

output frequency is:

((988 x 5 kHz) + 128 MHz) = 132.940 MHz

• for BCD switch settings in the range of

5000

9999 , subtract 5000 from the

switch setting, multiplying the result by 6.25 kHz and add it to the synthesizer

base frequency.

Example: An OSR-3H162 synthesizer has a base frequency of 150 MHz. The

selected channel number is 7205. The

synthesizer

output frequency is:

((7205-5000) x 6.25 kHz) + 150 MHz) = 163.78125 MHz

The key point to remember is that 5.0 kHz channel increments are selected with BCD

channel switch settings in the range of #0000 through #4999 and 6.25 kHz channel

increments are selected with BCD switch settings in the range of #5000 through #9999.

The operating frequency is determined as follows for Synthesizers having 8.333 kHz channel

increment capability;

• Multiply the BCD switch setting by 8.333 kHz and add it to the synthesizer

base frequency.

Example: An OST-3A128 synthesizer has a base frequency of 118 MHz. The

selected channel number is 0231. The synthesizer output frequency is:

3 SYNTHESIZER ALIGNMENT

3.1 General

OS(R/T)-3(A/H) enhanced synthesizer alignment is simplified by using a Type 84 subrack and RF

extender card/cable to provide receiver or transmitter power and signal interconnection.

Alternatively, +9.5 Vdc may be applied directly to a receiver or transmitter module through

positive connection to pins B6 / Z6, and negative connection to pins B30 / Z30 / B32 / Z32.

Receiver balanced audio (600 Ω) is available at pins B26 and Z26.

3.2 Repair Note

The OS(R/T)-3(A/H) synthesizer employs a high percentage of surface mount components which

should not be removed or replaced using an ordinary soldering iron. Removal and replacement of

surface mount components should be performed only with specifically designed surface mount

rework and repair stations complete with Electro Static Dissipative (ESD) protection.

When removing Surface Mount Solder Jumpers, it is recommended to use solder wick braid in

place of vacuum type desoldering tools. This will help prevent damage to the circuit boards.

3.3 Recommended Test Equipment

Alignment of the synthesizer requires the following test equipment or its equivalent.

Power supply - Regulated +9.5 Vdc at 2 A. Phillips PM 2811

Oscilloscope / Multimeter - Fluke 97 Scopemeter

Radio communications test set - Marconi Instruments 2965A

It is recommended that the radio communications test set be frequency locked to an external

reference (WWVH, GPS, Loran C) so that the internal high stability local oscillator may be

accurately set to within its ±1 ppm frequency tolerance.

3.4 OS(R/T)-3(A/H) Synthesizer Factory Configuration

The OS(R/T)-3(A/H) Synthesizer is factory configured as follows:

• Internal 9.6 MHz reference selected.

• VCO modulation by audio processor enabled (OS

TX versions only)

3.5 OS(R/T)-3(A/H) Synthesizer Alignment

3.5.1 General

Under normal circumstances, synthesizer alignment is accomplished without removing the

synthesizer from the MT-3 Receiver IF/Audio Board or the MT-3 Transmitter Main Board.

Alignment simply involves setting the internal TCXO reference frequency (if one is installed and

the internal reference option enabled). This step is described in "Reference Frequency Alignment"

of section 3.5.5.5. A change in synthesizer operating frequency greater than the maximum tuning

range for a particular model (Refer to Specifications section 1.3) from an initial factory setting

requires a slightly more involved alignment procedure as described in sections 3.5.2 to 3.5.5. To

convert a synthesizer with an internal reference source to a synthesizer requiring an external

reference signal or vice-versa is done through the appropriate selection of jumper JU1 A or B, and

JU2 (Refer to section 3.5.6).

3.5.3 Synthesizer Removal and Installation

The synthesizer module is fastened to the main board (MT-3 Receiver IF/Audio Board or MT-3

Transmitter Main board) with a single counter sunk Phillips machine screw accessible from the top

cover. Remove this screw to remove the synthesizer module. Using a plastic coated lifting tool,

such as a small screwdriver with the tip covered in heat shrink material, gently lift the synthesizer

module from the main circuit board by applying pressure in a rotating fashion about four corners

of the synthesizer module. It is

important

to gently remove the synthesizer module "straight out" in

order to prevent damage to the connector pins. Installation of the synthesizer is performed in a

fashion reverse to the above procedure. It is important to emphasize the importance of connector

pin alignment prior to any application of reinsertion force. Four corner locating pins assist in

connector pin alignment during installation and removal.

Note: Complete synthesizer alignment can be made without removing the synthesizer. The

alignment procedure starting in section 3.5.5 may now be performed.

3.5.4 Circuit Board Removal

Note: Circuit board removal is not required for tuning purposes.

Using a vacuum desoldering station, desolder connections P1, P2, and P3. Remove SMB

connectors J1 and J2 by desoldering the center pins and removing four M2.0 machine screws.

These connection points are shown in the "OS(R/T)-3(A/H) XXX - XXX MHz Analog Board

Component Layout (Top)" diagrams. Remove seven M2.0 machine screws and carefully remove

the analog circuit board. Removal of the analog circuit board will expose three interboard wire

connections. Carefully remove three ferrite beads and six Teflon washers from the inter-board

connection wires. Attempt to maintain the position of the three interboard wires in order to simplify

re-assembly. The digital board may now be extracted by removing four M2.0 machine screws.

Follow a reverse procedure to re-assemble.

3.5.5 Frequency Adjustment and Channel Selection

Connect a radio communications test set through a short section of low loss 50 Ω coaxial cable to

the synthesizer module SMB RF output jack (J2). Select the desired channel number through the

BCD frequency selection switches on the MT-3 Transmitter Main board or the MT-3 Receiver

IF/audio board (or through .the Frequency Programming Module). Turn the power off and on and

wait a few minutes for the oscillator to completely stabilize. It should be noted that the internal

synthesizer TCXO, if installed, operates continuously (regardless of the TX PTT state) when

installed in a transmitter. This continuous operation results in approximately 10 mA of additional

standby current.

The measured RF output signal should be within ± 1.0 ppm of the specified oscillator frequency at

an output level of +5 dBm. Note that unlocked synthesizer operation will be indicated by an

DE DANIELS

ELECTRONICS

3-4 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz

unstable or spurious RF output signal. The "Unlocked" red LED will also be illuminated when the

PLL is unlocked. Check that the requested channel number is within the frequency range of the

particular synthesizer model. An unlocked condition may be rectified by adjusting the VCO tuning

elements as described in the following procedures (no adjustment requires for the multichannel AM

Synthesizers). Note that there are variations in alignment procedures between the three synthesizer

family members as described in the following sections.

3.5.5.1 VHF OS(R/T)-3H 29 - 71.4 MHz VCO Alignment

Refer to the "OS(R/T)-3H 29 - 71.4 MHz Analog Board Component Layout" diagrams and the

"OS(R/T)-3H 29 - 71.4 MHz Analog Board Schematic Diagram" located in section 4 on pages 1, 2

and 3.

Using a high impedance (10 MΩ) DC Voltmeter, measure the PLL control voltage at TP4 located

on the synthesizer module analog board (top). Access to TP4 is available through the synthesizer

top cover. Using a small standard blade screwdriver, carefully adjust the VCO fine frequency

"TUNE" trimmer capacitor C24 until a test point (TP4) voltage of approximately +2.3 Vdc is

obtained. Measured PLL loop control voltages below approximately +0.5 Vdc and above

approximately +4.5 Vdc indicates an "out of lock" synthesizer condition.

If a test point (TP4) voltage of approximately +2.3 Vdc is unattainable through adjustment to C24,

then the coarse frequency jumpers, JU2-JU4 require modification in order to pull the VCO tune

range within the adjustment range of fine tuning capacitor C24. The top synthesizer cover must be

removed in order to gain access to the coarse frequency jumpers. The coarse frequency jumpers

(JU2-JU4) may be considered to be a selectable binary weighted capacitor element with JU2 being

the most significant "bit" and JU4 being the least significant "bit". The tuning resolution size is

≈12 pF (JU4). If the tuning voltage remains higher than +2.3 Vdc, decrease the tuning jumper

setting by 1 "bit" position and re-adjust C24 in an attempt to achieve +2.3 Vdc at TP4. For

example, if coarse frequency jumpers JU2-JU4 are all installed and represented by 111 then a

decrease by 1 "bit" position (12 pF) is represented by a binary jumper selection of 110; jumper

JU4 is not installed and jumpers JU2, JU3 are installed. Continue to decrease the jumper position

one "bit" at a time until the synthesizer regains lock with TP4 adjusted (C24) for +2.3 Vdc. If the

tuning voltage remains lower than +2.3 Vdc, increase the jumper setting by 1 "bit" position and re-

adjust C24 in an attempt to achieve +2.3 Vdc at TP4. Repeat this procedure until +2.3 Vdc at TP4

is achieved.

It is important to check the loop control voltage at TP4 when multiple synthesizer channels have

been programmed. All channel selections should result in a TP4 voltage within a +1.0 to +4.0 Vdc

range. Adjust the fine tuning capacitor C24 to center multiple channel voltages symmetrically about

+2.3 Vdc. Channel selections beyond the tuning range capability of the synthesizer will result in

unlocked operation. The tuning range capability of all synthesizer models is listed in the

Specifications section (1.3) of this manual.

microcontroller having no frequency adjustment capability. The OST-3A128 and OSR-3A149

models cover 118-138 MHz, and 139.4 - 159.4 MHz respectively and provide full band coverage

without tuning adjustment.

All channel selections might result in a TP4 voltage within the +3.1 to +3.5 Vdc range. Channel

selections beyond the tuning range capability of the synthesizer will result in unlocked operation

over the temperature range - 40C to + 60C. The tuning range capability of all synthesizer models is

listed in the Specifications section of this manual.

10 and 11.

Using a high impedance (10 MΩ) DC Voltmeter, measure the PLL control voltage at TP4 located

on the synthesizer module analog board (top). Access to TP4 is available through the synthesizer

top cover. Using a small standard blade screwdriver, carefully adjust the VCO fine frequency

"TUNE" trimmer capacitor C24 until a test point (TP4) voltage of approximately +2.3 Vdc is

obtained. Measured PLL loop control voltages below approximately +0.5 Vdc and above

approximately +4.5 Vdc indicates an "out of lock" synthesizer condition.

It is important to check the loop control voltage at TP4 when multiple synthesizer channels have

been programmed. All channel selections should result in a TP4 voltage within the +1.0 to +4.0

Vdc range. Adjust the fine tuning capacitor C24 to center multiple channel voltages symmetrically

about +2.3 Vdc. Channel selections beyond the tuning range capability of the synthesizer will

result in unlocked operation. The tuning range capability of all synthesizer models is listed in the

3.5.5.5 Reference Frequency Alignment

Adjust the synthesizer TCXO fine frequency potentiometer RV1 until the correct output frequency

is achieved. Access to this potentiometer is made available through an opening in the synthesizer

top cover. An RF power level of approximately +5 dBm should be measured at the synthesizer

module output connector and the frequency should be within ±1 ppm from the desired operating

frequency. Reference frequency adjustments should be made at room temperature (+20°C) after ten

minutes.
