1.1 INTRODUCTION

The Strider Link Series RPU&STL, Reportage Link System, Studio Transmitter Link and Auxiliary

Link System is a simple system designed to convey FM program material from a studio site to a

transmitter site like STL use. Also, it can be used like Reportage link when exists the need to

transmit parties, games, events and too many others applications. The Strider Link Series also

simultaneously conveys control and secondary programming subcarriers through MPX inputs.

This equipment may also be used to provide high-quality program transmission in intercity relay

service.

The Strider Link Series of equipment is a family of equiment that can operate in sveral bands from

170MHz through 450MHz. Strider STL Professional Link Series can operate up to 2,5GHz. This

operate manual covers the 170MHz, 200MHz, 300MHz and 400MHz bands of operation and the

various configurations in those bands.

Cards available to 2 different configurations:

The Strider Link system can be configured through cards that can be introduced by the customer

or even configured of it already manufactures internally with these cards. The customer can

choose in working with the basic system without additional card and according to need the cards

can be supplied.

The Strider Transmitter Link can work with a Stereo Generator Card to transmit programs in

Stereo operation. This card is very easy to install when the Strider Link package is bought without

any card.

Also, the second option is the Audio Processor Card, the user can choose to work with this card

and the Stereo Generator Card, the transmittion will have excellent audio quality with these two

cards.

Main Features:

In all of versions there is a LCD Display. RF, audio level, channel and other parameters are shown

on this LCD display. This display offers a very easy method of transmitter parameter monitoring

and a new level of easy for setup and installation, with metering accuracy normally only found on

expensive test equipment.

The FM modulator section in the Strider transmitters employs a fast PLL system and an excellent

VCO for extremely low audio distortion and high stereo performance.

A built in audio modulator provides crystal clear stereo sound and combined with the internal

compressor/limiter a fully compliant “plug and play” all in one link system on the Strider Multiplexx

with cards.

For future compatibility all settings are switchable with on board jumpers. The stereo and/or limiter

settings can be switched in and out to suit the requirements of any external broadcast equipment

you may have now and in the future (in the Strider Multiplexx - all cards installed)

The lightweight universal mains input design ensures a high reliability efficient design compatabile

with any mains system in the world.

1.3 System Features

In addition to establishing a new industry standard for performance, the Strider Link Series incorporates

many new and innovative features to aid in the installation, operation and maintenance of a system. Some of

the new features are:

* Very low distortion ceramic IF Filters offering unprecedented selectivity.

* Peak reading meter for all major functions.

* Decade logarithmic true signal strenght meter

* Channel marker and easy channel change.

* Important status functions implemented with LED indicators

* Designed to have a minimum of adjustments for trouble-free operation. Very easy to use.

* Modular construction that provides excellent shielding and at the same time allows easy access to

components.

* Multichannel Option: The Strider Link Series offers a large band of channels, in some models there are 40

Channels.

It is recommended that the manual be studied at least through Section 5 before

attempting to install the system.

1.4 Safety

1.4.1 Mains Voltage

This equipment operates from an AC power source of between 85 and 265V. There are hazardous voltages

present internally. PLEASE OBSERVE CAUTION WITH THE COVER REMOVED.

1.4.2 Swithed Mode Power Supply Hazard

Please note that the power supply units in this equipment is of the switched mode variety and have lethal

voltages present internally. The switched mode supplies are universal input fully approved type. They are non

serviceable modules and should be fully replaced should they fail.

1.4.3 Fuses

Only use fuses with the specified voltage and current ratings as stated on the back panel or pcboard. Failure

to do so may increase the risk of equipment failure, shock and fire hazard.

1.4.5 Radio Frequency

The N type RF power output socket contains RF voltages which may burn or present a shock. Please make

sure that the equipment is connected to an adequately rated load or antenna system while in operation.

1.4.6 Toxic Hazard

This equipment includes RF components that may contain Beryllium Oxide which is a highly toxic substance

that could be hazardous to health if inhaled or ingested. Care should be taken when replacing or discarding

such devices. Seek expert advice from the manufacturer should you physically damage a device that

contains Beryllium Oxide.

The main RF output power module contains Beryllium Oxide.

1.4.7 Other Safety Considerations

Do not operate this equipment in the presence of flammable gases, fumes or liquids

Do not expose this equipment to rain or water.

3-1 System Description - Strider Transmitter Link

Strider Link Series

SRFStrider-161004A-REV.A

Sinteck Sistemas Eletrônicos Ltda.

3.1 Strider Transmitter Link - Multiplexx - Audio processor and stereo generator

cards

The Strider Transmitter Link is a high fidelity broadband FM transmitter with a power output

of 8 Watts. It is capable of transmitting the program signal and two multiplex subcarriers with

little degradation of signal quality over one link. The linearity and FM noise characteristics of

the direct FM oscillator are exceptional. The transmitter is modular in construction and

operation, and the system description given below follows the signal flow through the varios

modules and its cards.

The system assembly drawings are located in Section “ Schematics” along with the

module schematics and system schematics are at the end of this manual.

Fm Synthesizer

The baseband signal from the audio inputs modulates the frequency modulated oscillator

(FMOSC) in the VCO Block. The FMOSC consists of a 170-450MHz ultralinear, very low

noise VCO which is phase locked to a crystal-controlled reference oscillator. The phase lock

loop contains the frequency programming mode which allow the synthesizer to be changed

in frequency steps of 250kHz (standard) 25kHz or 100kHz in some models. The RF signal

will deviate +-75kHz (composite) or +-50kHz (mono) from the carrier. The output power of

the VCO is approximatelly 5 milliwatt.

RF 50mW amplifier

In to the VCO block, there is a smaller RF amplifier section, that amplifiers 5mW from the

VCO output to 50mW through of 2 transistors.

RF 8W amplifier

The RF amplifier module internally consists of a two-stage MOSFET design, which

amplifies the input signal (50mW typ.) To the nominal 8W transmitter output. The output is

filtered to attenuate all higher order harmonics to a level of at least -60dBc. The output is

sampled via a dual directional coupler with detectors that provide an indication of the

forward and reflected power of the RF amplifier.The final stage current and voltage is

sampled and metered in this module.

Transmitter Control

The Transmitter Control section of the audio and power supply board has several functions.

One of these is to sense the PLL LOCK detect signal from the RF module. If this module

goes out of lock, then the radiate control logic circuit provides a signal to the power supply to

turn off the +7,2 VDC supply to the RF power module, causing the transmitter to stop

radiating. Also, this section detects if the VSWR level is more than permised, so the

transmitter control turn off the DC level to the RF power module.All of these parameters can

be view through the LCD on the front panel.

Metering and Status

The Metering and Status circuitry on the audio, Power Supply and RF sections conditions

the various system parameter samples for accurate meter indications, and drives the status

LEDs on the front panel.
