III — TRANSMITTER INSTALLATION
To ensure long and reliable trouble-free service from the UTX3KW-A transmitter the following steps for
installation are recommended.
1. MECHANICAL INSTALLATION: The UTX3KW-A was designed to be installed in a building
protected from the weather. The building should have a hard-surface oor such as concrete with a
moisture barrier. This barrier could be pressure-treated wood sub ooring which could be anchored
to the concrete and to the transmitter to make the installation earth quake resistant.
Allow a minimum of three feet around the transmitter cabinet for service access. The top of the
transmitter should be clear, for three feet above to allow the air to exhaust from the transmitter.
Air ow thru the transmitter is approximately 2500 CFM. Provisions for air inlet and exhaust from
the room must allow air ow with minimal obstruction. In the event that the room temperature
exceeds 35 degrees Celsius, cooling air must be provided so that the room temperature will not
exceed 35 degrees Celsius under worse case conditions.
Notice: This equipment is HEAVY and must be handled by professional movers with proper
equipment. Any damage caused by the installers is not covered under warranty. Check to ensure that
installing crews have proper insurance coverage.
2. GROUNDING: Transmitter grounding is VERY IMPORTANT and must be done correctly for
safety and operational reasons. A typical installation may be done as follows:
Use a heavy gauge wire such as #2 AWG strained copper or solid copper buss one (1) inch wide
by 1/8 inch thick for connections. The bonding between the transmitter and the ground rods must
be good quality and protected from corrosion. The ground wires should run over the oor and
connected to the ground rods located outside the building. The wire should not go thru the concrete
oor but over and around it.
3. AC WIRING: A ten (10) foot cable has been provided with the transmitter to facilitate the
connection to the AC Main power source.
Connections to the AC Main should be made as follows:
— RED, BLACK, AND ORANGE are connected to the 208 VAC 3-PHASE terminals
— WHITE WIRE is connected to the NEUTRAL terminal
— GREEN WIRE is connected to the SAFETY GROUND
NOTICE: All wiring of this type must be done by A QUALIFIED ELECTRICIAN and must
conform to LOCAL and NATIONAL wiring CODES.
Consult with your electrician to ensure that the proper breaker size is selected for the main circuit.
4. ANTENNA CONNECTION: The transmitter is equipped with 1 5/8 EIA Flange connector located
at the top of the rack. Conditions vary from site to site so some engineering may be required to
ensure that the antenna is receiving the correct amount of power to comply with FCC licenses and
to ensure safety from lighting etc.

IV— TRANSMITTER TURN ON PROCEDURE
Before applying AC Power to the transmitter for initial turn on and check out, the installation should
be approved by a qualied broadcast engineer. The turn on procedure that follows is recommended by
Pineapple Technology, Inc. engineering staff:
1. Check transmitter load or antenna for proper installation and connection to the transmitter.
2. Open the transmitter and inspect all cables and wires for loose connections or broken wires in the
rack assembly.
3. Check for damage to the equipment mounted in the rack.
4. Check all AC breakers and on/off switches to ensure that all are OFF.
5. TURN ON THE MAIN AC BREAKER LOCATED IN THE SUB-PANEL WHERE THE AC
POWER CORD WAS CONNECTED.
6. TURN ON THE MAIN AC BREAKER LOCATED ON THE ACDIS3 POWER DISTRIBUTION
PANEL LOCATED ON THE FRONT OF THE TRANSMITTER. A GREEN LIGHT SHOULD
COME ONE INDICATING POWER IS ON.
7. TURN ON THE AC SWITCH LOCATED ON THE FRONT OF THE ADP500. THE INDICATING
LIGHTS SHOULD BE ON AND READY FOR OPERATION
8. TURN ON THE AUX BREAKER LOCATED ON THE ACDIS3 FRONT PANEL. THE PA FANS
AND THE RACK EXHAUST FANS SHOULD COME ON.
9. TURN ON THE POWER SUPPLY BREAKERS LOCATED ON THE FRONT OF THE ACDIS3.
CHECK THE RR6000 POWER MODULES — six (6) EACH — TO SEE IF THE GREEN LIGHTS
ARE INDICATING NORMAL OPERATION.
10. USING THE ADP500 & PAS10 CHECK THE IDLING CURRENTS ON EACH PA TO ENSURE
THAT THE CURRENTS ARE IN THE CORRECT RANGE. TYPICAL RANGE IS 1.5 TO 2.5
AMPS. SEE ADP500 OPERATING SECTION FOR DETAILS.
11. TURN ON THE DRV100 DRIVER AMPLIFIER — THE GREEN LIGHT SHOULD COME ON.
NOTICE: The Modulator/Upconverter has been set at the factory so that the output power indication
on the ADP500 will show 100% or 3 KW p-sync power level. It is important to read the instruction
manual supplied with the modulator to locate key adjustment devices on the front panel. The output
level adjustment will be necessary for the next step in the turn on procedure.
12. Locate the level adjustment on the modulator/upconverter and turn the level down to minimum
or CCW.
13. Turn on the power switch located on the modulator rear panel.
PINEAPPLE TECHNOLOGY, INC.
UTX3KW-A Operating and Service Manual
14. Apply a video signal (1 volt P-P) to the video input terminal.
15. Slowly increase the output level adjustment while watching the RF Output level on the ADP500.
When the output gets up to 50% indicated power stop the adjustments.
16. Using the ADP500 reected power indication check the LOAD reected power. This should be
less that 5% reected.
17. Return to the PA current readings on the ADP500 to verify that all the currents are approximately
the same.
18. With successful performance thru step 17, the transmitter output power can be increased using the
output level adjustment on the modulator to achieve 100%. The aural power can be added at this time
not exceeding 10% of output p-sync power as indicated on the ADP500.

UTX3KW-A Operating and Service Manual
V— THEORY OF OPERATION
A. INTRODUCTION
The UTX3KW-A transmitter was designed to meet or exceed all FCC applicable specications for TV
Broadcast Equipment. Special attention was given to the selection of sub-assemblies and components to
achieve maximum reliability and minimum down time. The construction of the UTX3KW-A is BASIC
and MODULAR with most components eld replaceable. Special emphasis was placed on “KEEPING
IT SIMPLE” and returning to more traditional transmitter layouts and instrumentation.
This transmitter was designed for Analog (NTSC) transmission with provisions and options available to
convert to Digital Service when necessary.
Refer to the UTX3KW-A block diagram (page 15) for an overview of the transmitter architecture. This
will give the technician basic information needed to understand the operations of the transmitter and the
function of each subassembly.
SEE SECTION VI.A (Page 16) FOR PARTS LIST.
B. ACDIS3 AC DISTRIBUTION
The ACDIS3 is the primary AC power inlet module. The UTX3KW-A transmitter was designed to except
208 to 230 V AC 3-PHASE using a FIVE (5) wire connection. The ve wires are:
— 3 wires for 208-230V AC 3-Phase
— 1 wire for neutral connection
— 1 wire for safety ground connection
CAUTION: Connection to the AC Primary Source must be made using all ve wires listed above. Follow
the wiring instruction given in the AC WIRING (page 5; section III. 3.) If not followed, severe damage to
the transmitter and or electrical shock is possible.
The ACDIS3 performs the following functions:
1. Provides a primary AC power breaker point to shutdown the transmitter.
2. Provides 208 VAC power to each of the 2 KW DC power supplies with individual breaker points
for added safety.
3. Provides 110 VAC circuits for Modulator, ADP500, ABS (auxiliary power source), and AUX Power
where needed.
SEE SECTION VI.B (Page 17) FOR SCHEMATIC AND PARTS LIST
C. RR6000 POWER SUPPLY
The UTX3KW-A transmitter is designed with over 12 KW of DC power available to the transmitter. To
achieve this level, the power supply is made up of six (6) RR6000 power modules mounted into two (2)
main frame assemblies which are capable of managing three (3) 2 KW modules each.
The power modules are “HOT PLUGGABLE” and can be removed or installed without turning off the
transmitter.
Each power supply module has OVER VOLTAGE, OVER CURRENT, AND OVER TEMPERATURE
protection as well as a fault signal in the event of a failure.
REFER TO MANUFACTURER’S MANUAL PROVIDED WITH THE UTX3KW-A.
V — THEORY OF OPERATION

UTX3KW-A Operating and Service Manual
D. ADP500 & PAS10 PERFORMANCE MONITOR
The ADP500 & PAS10 (PERFORMANCE MONITOR) provides the following functions:
1. Monitors FORWARD AND REFLECTED POWER to the antenna and presents it as a percentage
of power rating. The transmitter comes set to 100% P-Sync power based on the ratings of the
transmitter.
2. Monitors Aural Power as a percentage of P-Sync rating (5-10 % typical)
3. Provides a HIGH ANTENNA VSWR MONITOR in the event of an antenna or coax failure where
the reected power exceeds 25% the transmitter will shutdown. Front panel LED will change from
green to red in case of a fault.
4. Provides current monitoring of all the pallets used in the six (6) U600LDV-2 power amplier
assemblies. The current levels can be read directly from the multi-meter on the front panel.
Individual pallets are selectable on the ADP500 and the PA assemblies are selected using the PAS10.
In normal operations, a PA FAULT is indicated by going from green to red. RED indicates that the
current level is below 500 ma and a transistor could have failed. To read the actual current, select the
appropriate PA Bank using the PAS10. The ADP500 will now display status of each pallet in that
PA. The multi-meter will read the actual current.
5. A PA INHIBIT switch is provided for failure diagnostic purposes. When activated, this switch allows
the technician to monitor the bias currents for each pallet. These readings should be recorded when
the transmitter is rst installed and used as a reference. This is the best way to trouble shoot possible
transistor problems. When in the PA INHIBIT mode, the RF PWR OFF LED will change from
green to red indicating that the “SHUTDOWN LINE” is at a TTL 0 state and the output power
has been reduced to near zero.
6. An RF MONITOR port (BNC) is available to connect a spectrum analyzer for monitoring the
output signal.
METER SELECTOR SWITCHES
The PAS10 is used to select the appropriate PA Module (U600LDV-2) for performance display on the
ADP500. PA designations are PA1 starting from the top row going left to right with PA6 being on the right
side in the third row down when viewed from the front of the transmitter.
The Rotor Switch on the ADP500 is the detail selector for the multi-meter. The various positions are
dened as follows:
PA1 THRU PA5 ................................................... Reads PA pallet currents as selected
Typical reading in INHIBIT MODE 1.5 TO 2.2 A
Typical reading SMPTE BARS 5-7 A for PA1 thru PA4
Typical reading SMPTE BARS 2-3 A for PA5
PA6 .....................................................................NO CONNECTION
PS VOLTS............................................................ Reads DC voltage applied to PA stages
Typical reading would be +29 to 32 VDC

E. REMOTE MONITOR AND CONTROL WITH ABS
This equipment is OPTIONAL and can be used to satisfy FCC remote control requirements.
The Remote Monitor is used to monitor the operational status of the transmitter and will allow the
operator to turn RF on or off and adjust power levels. The following items are monitored or controlled:
1. Transmitter on/off function
2. Power output level monitor and adjust
3. AC Line voltage status — With ABS you can be notied if there is a power failure at the side.
4. Various other custom options are available. Specify these at the time the transmitter is purchased
and they will be included if possible.
Remote monitoring requires a phone line connection. Information can be accessed via a PC Terminal or
via a “VOICE COMMAND LINE.” Either option is standard with this system.
The Auxiliary power unit requires a battery connection. A common car battery (12 VDC) can be used
with a charger as an ABS. This will run the Monitor and provide access to transmitter status for several
hours.
A manual for this equipment is provided by the Manufacturer and is included in the UTX3KW-A package
shipped with the transmitter. This manual is only included if this option was purchased for delivery
with the transmitter.

K. UC3KW-DC40 COMBINER/DD COUPLER
The UC3KW is a 6-way in phase combiner with built in 40 dB dual directional coupler. The combiners
are designed for the channel designated for the transmitter. This is a closed unit and cannot be serviced.
SEE SECTION VI.G. (Page 38) FOR PARTS LIST
L. BPU3KW UHF BAND PASS FILTER
This Band Pass lter was designed to meet FCC Certication requirements with minimum loss of RF
Power. The BPU3KW comes tuned and tested to the operating frequency of the transmitter and should
not be adjusted without proper equipment. Replacement lters are available as P/N BPU3KW UHF
(+CHANNEL NUMBER).
M. AUX5 MONITOR PANEL
The auxiliary monitor panel provides analog meter measurements for the primary DC supply. The total
power supply current and voltage are displayed on these meters. These measurements serve as a good
indication of the operations of the transmitter nal power ampliers.
Each power supply has a current monitor output. These outputs are accessible on the AUX5 Front panel.
Each ( PS I SHARE ) test point will indicate a relative amount of current being supplied from the power
supply. This is not a calibrated or accurate measurement that is scaled from the current capability of the
power supply. This is also a second-level diagnostic tool for use by qualied technicians.
In the event of an EMERGENCY, a SHUTDOWN SWITCH located on the AUX5 will shut down the
transmitter and remove all power starting from the MAIN 3-P BREAKER. To turn the transmitter on,
it is necessary to RECYCLE the SHUTDOWN SWITCH before the transmitter MAIN BREAKER can
be turned on.
N. FP6 FUSE AND SHUNT PANEL
The FP6 serves as a DC SUMMING POINT for all current coming from the power supplies. After being
summed the current passes through a 500 AMP precision shunt which is used for measuring the total
supply current and voltage being applied to the transmitter power ampliers. At this point, the DC Power
is distributed to each U600LDV-2 amplier assembly thru a series 80 amp fuse.
NOTICE: BEFORE ANY SERVICE WORK IS PERFORMED ON THE FP6 ALL POWER TO
THE TRANSMITTER MUST BE TURNED OFF FOR SAFETY.

VII — ROUTINE MAINTENANCE
VII — ROUTINE MAINTENANCE
The following KEY MAINTENANCE AND PERFORMANCE CHECKS should be made monthly or more
frequently in some environments where dust is a problem:
TRANSMITTER
• Remove and clean the air lters with a light detergent and DRY COMPLETELY before re-installing. Dirty
lters will cause PA amps to shutdown resulting in a loss of RF Power. Spare lter P/N 990199 is
available from Pineapple Technology, Inc.
• Check and record the voltage and current meter readings on the ACDIS3 (AC AND DC DISTRIBUTION
UNIT LOCATED NEAR THE POWER SUPPLIES). NOTE: current readings will vary with picture content,
Therefore a standard video waveform such as SMPTE BARS should be used.
• Using the ADP500 & PAS10 — record the bias level settings on each PA Pallet by selecting the appropriate
PA with the selector switch. To make this measurement of BIAS ONLY it is necessary to activate the PA
INHIBIT switch momentarily for each reading.
• Using the ADP500 — check and record the RF Output power level to ensure that it is still reading 100%
+/- 10% from the previous settings.
• Using the ADP500 — check and record the VSWR (Reected power) to ensure that it is still reading only a
few percent indicating normal load operations.
• Using the ADP500 — check and record Aural power readings. This is normally set at 10% of P-sync. Expect
this to vary only a few percent from reading to reading.
• Carefully inspect RF Output coax and coaxial ttings for excessive heating or discoloration.
• Check DC power connections on shunt panel and power supplies for over heating and tighten as needed.
• Check DC connections on PA rear panel.
FACILITIES
• Clean all air inlet lters and exhaust outlets to ensure that the transmitter is getting clean unobstructed
air ow.
• Perform recommended service on air condition systems.
• Rodent traps or baits should be renewed to keep the facilities clear of these pests which can cause damage
to the transmitter.

VIII — ADJUSTMENTS AND TUNING
VIII — ADJUSTMENTS AND TUNING
The UTX3KW-A is basically an FCC Type Certied broadband transmitter with a few frequency selective
sub-assemblies. A list of these sub-assemblies are listed below and followed by general instructions where
applicable:
A. MODULATOR — Instructions for making adjustments to the modulator are included in the
Manufacturer’s Instruction Manual.
B. BPU3KW Band Pass Filter comes adjusted to the channel as purchased. To change frequency
would require a tuning adjustment to the lter. To perform this adjustment it is necessary to use a
NETWORK ANALYZER and a signal generator with necessary I/O Adaptors to connect to the lter.
The Technician performing this adjustment should be skilled in tuning Band Pass Filters. If the target
frequency is outside of the tuning range of the lter, it becomes necessary to purchase a new lter.
Replacement lters and service is available from Pineapple Technology, Inc.
C. U600LDV-2 POWER AMPLIFIER MODULE — The U600LDV-2 has three areas where adjust-
ments may be necessary over time or in the event of a frequency change. These areas are:
1. Bias adjustments: The LDMOS FET devices used in these pallet ampliers are set to 500ma/device
side or a total of 1 amp/device. This adjustment can be made on the bench by rst terminating the
input and output with 50 ohm terminations. Apply 31 volts DC to the PA using a power supply that
can provide a minimum of 15 amps. Note: a cooling fan will be necessary to cool the amplier
during this adjustment.
To adjust the bias’ it is best to turn all the bias adjust resistors CCW or to minimum on the pallet
being adjusted. Using a clamp on the AMP Meter connected to the DC Feed terminal — located
on the DC ISOLATION AND CURRENT MONITOR BOARD — measure the current levels. The
rst resistor is increased to 500ma indicated on the Amp meter. Repeat this adjustment for each
additional resistor for reading of 1.0 A, 1.5 A, and 2.0 A. This will indicate that each device half
is set to 500 ma.
This concludes the bias adjustment procedure. This adjustment should be made at any time when a
device has to be replaced. Normal bias ranges from 1.5 amps to 2.3 amps per pallet as indicated on
the ADP500/1000. DO NOT USE THE ADP500/1000 CURRENT READINGS FOR MAKING
BIAS ADJUSTMENTS.
2. PA PALLET RF circuit tuning: These circuits are broadband and xed tuned providing no adjust-
ments. Any tuning at this level is performed by the factory.
PINEAPPLE TECHNOLOGY, INC.
UTX3KW-A Operating and Service Manual
Page 57
VIII — ADJUSTMENTS AND TUNING
3. GAIN & PHASE MATCHING: Each U600LDV-2 comes with a circuit for making Gain and Phase
adjustments. This adjustment is xed tuned for the channel of this transmitter. Adjustment to these
circuits require the following equipment:
• HP 8508A VECTOR VOLTMETER
• BIRD THRU LINE WATT METER
• SPLITTER
• 2ea DIRECTIONAL COUPLERS
• 2 ea. 500 watt terminations
• Component selection charts for resistors
• Component selection chart for capacitors
Component selection charts and setup block diagram provided as needed. Recommended tuning
should be within +/- 0.15 dB and +/- 3 degrees as measured on the HP 8508A.
D. PHASE MATCHED CABLES: The cables used to connect the splitter to the PA Amplier inputs
and those provided to connect the PA Ampliers to the combiner are phase matched. If a cable
is damaged and needs to be replaced, additional cables are available from Pineapple Technology,
Inc. The customer may manufacture additional cables, however the same coax type with the same
connector types should be used. The phase matching procedure listed above may be used for
adjusting the lengths. Matching should be within +/- 2 degrees.
E. ADP500/1000 WATT METER: This unit comes calibrated from the factory for the rated power
level of the transmitter. Adjustments are not recommended in the eld.

to contact Pineapple Technology, Inc. for assistance. If it is necessary to perform eld service on the
transmitter, most parts are available from Pineapple Technology, Inc. for next day shipment.
The failure analysis of the transmitter starts off with the following assumptions:
A. The transmitter is connected to an AC source which is within the specied voltage range and has
ample power to run the transmitter. This would normally be 208-230 V AC 3-phase with a minimum
of 75 Amps available.
B. The antenna has been checked out and veried to have a VSWR of 1.2:1 or better.
C. The room temperature is < 35 degrees Celsius.
D. There are no restrictions on the air ow in or out of the building.
E. The video and aural signals, to the Modulator, comply with stated specications.
CHECKING THE WARNING LIGHTS
MFA1KW: This unit has dual performance indicator lights located above the air inlets. One set of lights
for each PA assembly located inside the unit.
HS OVER TEMP GREEN NORMAL
RED FAULT
+28 VDC GREEN NORMAL
RED FAULT
FAN SUPPLY GREEN NORMAL
RED FAULT
HS OVER TEMP FAULT could indicate one of the following problems:
a. Room temperature is too high and the heat sinks are over heating
b. High VSWR on PA output port will cause the Dump-load sensor to fault.
c. Air lters are dirty and need to be cleaned.
d. Exhaust fan failure (located in the top of the rack).
+28 VDC FAULT could indicate a power supply failure. Check the ADP500 & PAS10 for PA voltage and
current readings. The power supply modules will also indicate a loss of power.
FAN FAULT indications could mean that the PA blower has failed or there has been a loss of AC power
to the fan. There is also a fuse located just inside of the front panel in case there is a locked rotor failure

condition. To access the fuse, the MFA1KW must be removed from the rack and the top cover removed.
This is a 5 AMP 3 AG type fuse.
ADP500: There are a number of fault indicator lights on this unit that can be used for trouble shooting
possible problems with the transmitter.
With normal operating conditions, all the LEDs located on the front panel should be green. Red lights
could indicate a fault in normal operations of the transmitter. Fault indicators are listed below:
a. ANT VSWR HIGH light is RED. This indicated that the antenna reected power exceeds the set
point in the equipment which is normally set to 10 %. When this LED is on, the transmitter shutdown
line is pulled down to ZERO and the transmitter RF PWR OFF LED will also light RED indicating
that the transmitter has been shutdown at the driver level. This condition will automatically reset
when the problem is corrected. CHECK THE ANTENNA FOR POSSIBLE FAULTS.
b. RF PWR OFF light is RED. This will occur anytime the “SHUTDOWN LINE” is pulled to ZERO.
This control line is pulled to ZERO with any of the following faults:
1. ANT VSWR HIGH
2. PA INHIBIT SWITCH IN THE INHIBIT MODE
NOTICE: ONLY THE PA INHIBIT SWITCH OR THE ANT VSWR HIGH WILL SHUTDOWN
THE TRANSMITTER DRIVE CAUSING THE RF OUTPUT TO FALL TO NEAR ZERO.
c. PA1 THRU PA5 LEDs RED would indicate that the PA Pallet current level has fallen below
the set point and could indicate a transistor failure. The normal current with the “inhibit” switch
activated is 500 ma.
RR6000 POWER SUPPLY MODULES
The Power Supply module has two warning lights located on the front panel. Normally these lights are
GREEN indicating that the AC Line voltage and the Over voltage circuits are within their normal range.
Should either go out of range, the lights will turn RED and the power supply module will shutdown. This
will reduce the available power to the RF Stages and could result in lower RF Output Power from the
transmitter. If this happens, turn off the transmitter for about one (1) minute and then turn it back on. If
this warning continues, the modules should be removed from the rack and returned for service — a spare
module should be installed to maintain normal operations.
NOTICE: The UTX3KW-A transmitter has six (6) each 2 KW power modules. Under normal conditions,
this is enough head room to allow the removal of one power supply module with little or no reduction in
output power. In the event it becomes necessary to remove a module and the RF Output power drops,
the RF Drive level from the Modulator can be reduced to a point where the DC Volt meter on the
ACDIS3 reads 31 volts. This is the maximum output level obtainable with one power supply module
removed. On this transmitter that could be a reduction of less than 500 watts in operational output power.
This will keep the station on the air until the new power supply module arrives. DON’T FORGET TO
TURN THE DRIVE LEVEL UP AFTER INSTALLING THE NEW SUPPLY TO RETURN TO
100% OPERATION.
