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 inthose 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 extremelylow audio distortion andhigh stereo performance.
A built in audio modulator provides crystal clear stereo sound and combined with the internal
compressor/limiter a fully compliant “plugand play”all in one link systemon theStrider Multiplexx
with cards.
For future compatibility all settings are switchablewith 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 havenow and in thefuture (in theStrider Multiplexx - allcards installed)
The lightweight universalmains input designensures a highreliability efficient designcompatabile
with any mainssystem in the world.

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 iscapable of transmitting the programsignal andtwo multiplex subcarriers with
little degradation of signal qualityover one link. The linearity and FMnoise characteristics of
the direct FM oscillator are exceptional. The transmitter is modular in construction and
operation, and the system description givenbelow follows the signalflow through the varios
modules and itscards.
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 whichis phase lockedto a crystal-controlledreference oscillator. The phaselock
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 isapproximatelly 5 milliwatt.
RF 50mW amplifier
In to the VCO block, there is a smaller RF amplifier section, that amplifiers 5mW from the
VCO output to50mW through of2 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 meteredin this module.
Transmitter Control
The Transmitter Control section of the audio and powersupply 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, thenthe radiate control logic circuitprovides asignal tothe 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 controlturn offthe DClevel to the RF power module.Allof these parameters can
be view throughthe LCD onthe front panel.
Metering and Status
The Metering and Status circuitry on the audio, Power Supply and RF sections conditions
the varioussystem parameter samples for accurate meterindications, and drives the status
LEDs on thefront panel.

Strider Link Series
SRFStrider-161004A-REV.A
Sinteck Sistemas Eletrônicos Ltda.
Power Supply (AC)
The Power Supply board located out of the main PC board of the Strider Transmitter Link
converts anyof AC voltages (full-range 85up to 265VAC)into the 12V regulatedand filtered
voltage.
In the main PC board of the Strider Transmitter Link, exist others four DC regulators that
supplies the voltages required for the operation of the transmitter. The outputs are: +10V, 10V and +5V for the most of the system electronics. A high current +7,2V supplies the RF
power module. +5Vsupplies only themetering section.
External Power Supply (DC)
The Strider Transmitter Link can be configurated for DC operation too. There is In the rear
panel a connector to connecting a +12V battery. Internally the transmitter has a switching
power supplies to provide the system voltages. The RF power module is supplied of +7,2V
through an auxilliary switching power supply that sure maximum power until the battery
presents low charge. This external battery can present 10,8V at minimum and 14V at
maximum voltages.
Audio Processor Card
Optional, the user can obtaincards forsimple connectionto the Strider Transmitter Link, the
first card is an audio processor dual-band, that processes independently low and high
frequencies, always maintaininghigh the dynamicsof the transmission.This processor can
be enabled or disabled in the front panel. The audio processed is limited and it won't
produce over-modulation inthe transmitter, in additionthe sound qualitywill be exceptional.
Stereo Generator Card
The Stereo Generator Card consists in an AMDSB/SC stereo generator of excellent audio
separation. Also, the user can choose if the transmittion will be in stereo or mono. The
parameters of thiscard can beviewed on theLCD of theequipment.
Digital 15kHz Low-pass Filter
The digital 15kHz filter card is indicated for who needs to transmit programming that the
audio frequency does’t pass of 15kHz. Is most important to place this card when is installed
the stereo generator card, because the high frequencies is not important to transmit in this
case.

3-3 System Description - Strider Receiver Link
Strider Link Series
SRFStrider-161004A-REV.A
Sinteck Sistemas Eletrônicos Ltda.
The Strider Link Receiver series has two different types of receivers which are designed for
different RF environments. The most popular version is the “Link Receiver” that is a singleconversion receiver that provides maximum performance in all but the most demanding
environments. The model “Triple-C Link Receiver” is triple-conversion receiver which
provide maximum out-of-band and adjacent channel protection. The Triple-C exhibits
superior front end performance in the presence of extremely strong RF fields, as it uses
modules from thetime-proven Sinteck Next.
Both systems are selectable to support mono or composite operation. The receivers are
single in construction and operation, just one PC board, and the system description given
below follows thesignal flow inthe block diagramsreferenced above.
The model “Triple-C Link Receiver”is not explainedin this manual.
The system assembly drawings are located in section “schematics” along with the
module schematics and assembly drawings. The system block diagrams and system
schematics are at the end of this manual.
Preselector/Preamplifier - Front End
The Preselector/Preamplifier is located out of the main PC board of the receiver. The
antenna input signal is first passed through the preselector filter section, which is a threeelement helical bandpass filter with a 5MHz bandwidth with very low insertion loss. The
output of the preselector filter is fed to the preamplifier providing low-noise gain. The
postselector filter providesfurther filtering aswell as imagenoise rejection.
Preselector Filter and Booster
A second filter located on the preselector filter consists in other RF filter and amplifier
presenting high gainand low distortion.
Preamplifier
The output of the Booster is fed to the preamplifier on the RF section of the receiver. This
preamplifier incorporates an adjustable gain circuit and schockty barrier diodes attenuators
for user-adjustable front end protection and isolation. The low noise, high-intercept point
preamplifier is followedby the imagenoise filter.
Local Oscillator
The Local Oscillator 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 or100kHz in somemodels.
Mixer and IFDemod
The mixer and IF Demod are located together the same component. A modern IC does the
both functions with the best performance. The carrier frequency provenient from the
Oscillator is mixed into the IC with the antenna signal to provide down direct-convesion to
the 10,7Mhz IntermediaryFrequency.TheIF is buffered to overcomemixer conversion loss.
The IF Demodmodule provides downconversion to the 10,7MHz,sets system selectivityin
this IF, extracts the baseband information from the carrier, provides the logarithmic RF
signal strength voltage for metering, and establishes the mute threshold point of the
receiver.

Sinteck Sistemas Eletrônicos Ltda.
Audio/Baseband section
The main functions of the Audio/Baseband section on themain PC board ofthe receiver are
to split the baseband signal into three outputs: 30Hz to 75kHz to the MPX output BNC
connector.
For mono, the split is 30Hz to 15kHz to the Mono XLR connector.The usercan chooseif this
active filter inthis output isdisabled or enabledthrough internalljumpers. So, itis possible to
transmit 30Hz to 75kHz through this XLR connector. This module contains a mute switch,
controlled by the main processor and the mute comparator output of the Mute and Transfer
circuitry. The signal is then passed through a high frequency amplitude corrector, which
compensates for the baseband high-frequency roll-off caused by the 10,7MHz IF bandpass
filters, to restoreproper amplitude responseto the basebandsignal.
The signal level is adjusted by the processor, beetwen 0% and 100% (normally 0V to 4Vpp)
in both outputs,MPX and Mono.
For Stereo demod operation, 2 XRL connectors was placed, the Stereo demod section
provides an excellent stereo separation through a modern IC. In this point, the signal level
has not adjust and a fix level of 0dB normally is found in the 2 XLR outputs (left and right). To
mute the stereo demod, the user have to accede the internal jumpers, that originally come
no-muted (See “jumperssection - configurations”).
Mute and Transfer Section
The Mute andTransfer circuitry locatedin the mainPC board ofthe receiver mutesthe audio
signal during periods of insufficient RF signal strength orfor transferingoperation to another
receiver. This function is only available to the XLR connectors selectable by internal
jumpers, not forMono (XLR connector) and MPXoutput ( BNCconnector).
Metering and Status
The Metering and Status circuitry, located in the front panel PC board, condition the
metering samples and drives the status LEDs on the panel, also is possible to change any
parameter of the receiver, like choose channel and volume level. Remote status functions
are also provided.
Power Supply (AC)
The Power Supply section of the main PC board converts any AC input voltages
(110V/220V) into the three regulated voltages, required for the operation of the receiver.
The outputs are +12V,-12V and +5V for the most of thesystem electronics.Aregulated +5V
supply the mainprocessor and LCDdisplay backlight.
Remote Control
The Remote Control section in the receiver is a circuitry responsible to change the state of
the relay. This function is possible to connect auxiliary systems in the receiver, that will
change the state when the RF signal in the antenna is more than 10% of the maximum
signal. This parametercan be viewedthrough the LCDon the frontpanel.

ALARM FAILSVIEW
1) PLL Unlocked
This fail can happen in the case that PLL system doesn't reach enough voltage to get lock
the VCO . The principal cause of this fail can be the initial moment when the Strider
Transmitter Link is turned on, in this case, observe that the second led that corresponds to
the “PLLLocked” doesn't light. This fail type can happen in less than 1% of the cases when
the equipment is altered the frequency out of the factory. Coming of it manufactures, the
equipment is adjusted among 1/2 VCC that means that the restraint bow is quite big and this
warning won't surelybe exhibited inany case.
3
This view indicatedare “readings”, andtherefore cannot bemodified.
2) VSWR PROTECTION
The Strider Transmitter Link is equipped with a modern and intelligent circuit to protect it for
any kindof antenna fail. Ifin the case that the antennais disconnected, the transmitterautoprotect itself automaticallyreducing the RFlevel to 0W.
Also, if the coax cable has not good impedance or fail in any connection, simplest the
equipment reduces thepower and worksin fold-back mode.
This circuitry isvery fast, allowingthat the transmitterhas a longlife.
Note that in the front panel exists a led to show if the RF power is operating, in this safety
mode, this ledwill be turnedoff.
This view, like the“PLLUNLOCK” are only“readings”and therefore cannotbe modified.

STRIDER RECEIVER LINK -QUICK START GUIDE FORINSTALLATION ANDUSE
This chapter contains the necessary instructions for the installation and use of the
equipment Strider Receiver Link. In case some aspects are not totally clear, for instance
when a user is using this equipment for the first time, we advise the new user to read
carefully the entiredescription contained inthis manual.
PREPARATION
Unpack the Strider Receiver and check, before making any operation, that the unit has not
suffered from any mishandling during the transport. In particular check that all the
connectors are inperfect conditions.
Check that thesupply voltage coincideswith the AC voltageavailable.
The input supplyfield is of:
STRIDER RECEIVER LINK: 110V or 220Vswitchable
Check that the switch located in the rear panel of the equipment is in position equivalent to
the available voltage.
Check thatthe switch located in the front panel of theStrider Receiver Link is in the position
“OFF”
The Strider Receiver Link has this switch which interrupts completely the AC supply of the
unit.
Connect the antennainto the RFinput connector.
Connect the AC cableto the corresponding VDE socket.
REMARK: It is essential that the AC network has an accurate grounding system in order to
ensure both thesafety of theusers and thecorrect functioning ofthe unit.
USE
Switch onthe receiver by puttingthe selector on the position “ON”the switch situated onthe
front panel.
The following messagemust be viewed:

Note that this moment if possible to change the frequency of operation on the Strider
TransmitterLink.
REMARK: Make sure that the antenna can respond to all frequencies of the Strider Link,
that has 5MHz bandwidht at minimum. The Strider Receiver Link has a dual cavity system
with highgain, if the antennais outof the central frequencythe user will note that thelevel of
RF-in is lessthan “MAX” ifthe Strider Transmitter link is operatingnear from thisreceiver.
