Its power output is continuously adjustable from 10W to 150Winto a 50 Ohm load.The XT150 incorporates a stereo coder which guarantees excellent stereoseparation together with low harmonic distortion (only for Stereo version). Italso accepts two SCA signals. A front panel switch allows stereo operation (onlyfor stereo version) or "mono/mpx" operation which excludes the stereo encoderand uses the "right" input as the mono input and the "left" input as the widebandcomposite input. The specification features low audio distortion andintermodulation figures (typically 0.03%) and a high signal-to-noise ratio(typically -80 dB). A voltage selector on the transformer primary allows a varietyof supply voltages to be used.1.3 METERS AND INDICATORS1.3 METERS AND INDICATORS1.3 METERS AND INDICATORS1.3 METERS AND INDICATORS1.3 METERS AND INDICATORSThe operating parameters of the exciter can be monitored using the analogmultimeter (12 Fig.1A and 8 Fig.1B) situated on the front panel. The parameterto be measured is selected by the rotary selector (11 Fig.1A and 7 Fig.1B). Thefrequency control (10 Fig.1A and 14 FIg.1B) allows frequencies to be selectedin steps of 10KHz. Three red alarm leds indicate VCO unlock (15 Fig.1A and 11Fig.1B), excess VSWR on the output and the excess of temperature (4 Fig.1A and8 Fig.1B), and the shutdown condition, programmed by a remote command (10 Fig.1Aand 6 Fig.1B). Three green leds (7 Fig.1A and 3 Fig.1B) indicate the presenceof +12V, +15V and +28V voltages which are used to power the various cards insidethe exciter. A selector (2 Fig.1A) allows selection between Mono/MPX and Stereofunctions and another selector (6 Fig.1A and 2 Fig.1B) is provided to choosethe level of the input signal. Trimmers are provided for adjustment of left andright channels (5 Fig.1A and 1 Fig.1B) and a switch allows the stereo subcarrierto benabled or disabled (3 Fig.1A).1.4 AUTOMATIC FREQUENCY CONTROL1.4 AUTOMATIC FREQUENCY CONTROL1.4 AUTOMATIC FREQUENCY CONTROL1.4 AUTOMATIC FREQUENCY CONTROL1.4 AUTOMATIC FREQUENCY CONTROLThe operating frequency is governed by a thermally-compensated, reference

To aid understanding, the unit has been subdivided intoblocks, each of which is fully described below. The block diagramis shown in Fig.3.2.2 POWER SUPPLY2.2 POWER SUPPLY2.2 POWER SUPPLY2.2 POWER SUPPLY2.2 POWER SUPPLYThis circuit comprises a board, mounted on a heat sink, which is fixedto the central part of the lower section of the unit (2 Fig.5). The powersupply generates the various stabilized voltages necessary for each ofthe various modules that make up the XT150. The transformer has aselectable input from 110 V to 240 V and two outputs A +18V (6.3A) andB +32V (10A). This power supply is composed of two main parts: afterhaving undergone filtering for mains-borne interference, the supply istransformed into four lower voltages, rectified, smoothed andstabilized to the following values: +12V, +15V and 10 to 28V variableto obtain the high efficiency (85-90%). The +15V supplies the encodermixer, the PLL card, the VCO card, the meter 100 card and the alarm card.The +12V supplies the input of RF power amplifier driver (BGY33) andthe 10-28V variable supplies the output of RF power amplifier driver(BGY33) and the final power stage of the same module (two MRF317 or twoSD1480).The variable voltage of the final stage is controlled by the PWR ADJcontrol which determines the R.F. power output of the exciter. Theautomatic control of output power guarantees the power level set by thePWR ADJ control right across the frequency range and independantly ofother variables such as temperature, load variations etc. The systemworks by comparing the value set by the PWR ADJ control with the actualpower output of the unit and compensating accordingly. The final stagedriveris composed of two separate parts, the input part is supplied with+12V voltage, and the output part is supplied by the switching powersupply with 4-12V variable voltage obtained dividing the 10-28Vvariable voltage. A power limiting circuit intervenes in the eventof excess SWR on the output, thus protecting the final stage.2.3 AUDIO INPUT CARD2.3 AUDIO INPUT CARD2.3 AUDIO INPUT CARD2.3 AUDIO INPUT CARD2.3 AUDIO INPUT CARDThis card is situated on the rear panel of the exciter (1 Fig.4 and 3Fig.5). The card filters all audio signal inputs to the unit, removingRF interference, before supplying them to the encoder mixer or Mono\MPXcard. The main operating parameters of the exciter are available forremote monitoring via a telemetry connector.

The function may be selected by acontrol situated on the front panel. In stereo encoder mode, the 19KHzpilot tone is derived from a quartz crystal reference oscillator. Sotoo is the samplingfrequency which allows the L and R signals to be separated from themultiplexed signal, plus the suppression of the 38KHz frequency. Thelevel of the left and right signals is set by the corresponding selectorsituated on the front panel. The signals are then filtered at 15KHz andpre-emphasized (50µS CCIR, 75µS FCC) before being sent to the multiplexcircuit. The audio signals from the two SCA inputs are mixed in to providethe output. In mixer mode (Mono MPX) the stereo encoder is bypassed,the right input accepts a mono signal and the left input accepts amultiplex signal upto 100KHz. The SCA inputs remain unchanged. Threerectifiers allow the peak levels of the two inputs "Left/MPX" and "right/mono" to be displayed on the analog meter, and provide the audio detectorcircuit with the deviation level.2.5 PLL CARD2.5 PLL CARD2.5 PLL CARD2.5 PLL CARD2.5 PLL CARDThe PLL card is situated internally, in the upper part of the unit (6 Fig.5). The circuit includes a reference cristal oscillator (optionalhigh stability), a logic section that includes the frequncy dividersand comparator. The reference cristal oscillator generates a 4MHzfrequency that is divided to generate a 1KHz fixed signal. This signalis compared to the operating frequency generated by the VCO dividedopportunely on the ground of the frequency setted on the Contraves. Anindicator situated on the front panel signals the "unlocked" condition.The comparator output (AFC signal) is sent to the varicap diodes situatedon the VCO Card.2.6 VCO CARD2.6 VCO CARD2.6 VCO CARD2.6 VCO CARD2.6 VCO CARDThe VCO card is situated internally, in the upper part of the unit(4 Fig.4). This module includes an audio input stage at low frequency,a voltage controlled oscillator at low noise (VCO) and a driver stage.The audio signal supplied by the encoder mixer is amplified and theninjected into the VCO to provide class F3 modulation. The voltagecontrolled oscillator (VCO) generates the signal on the frequency settedon the Contraves. This signal is amplified to 300 mW level (25dBm) todrive the final stage and to be sent to PLL circuit situated on the PLLcard. The operating frequency genereted by the VCO is divided down before
XT150 and XT150S Technical and Maintenance ManualPag. 11being compared to a reference frequency, generated by a high stabilityoscillator (standard 5ppm). The error voltage is filtered and used tocompensate the VCO frequency and guarantee its stability. A trimmer ispresent on this card for adjustment of deviation.2.7 R.F. POWER AMPLIFIER2.7 R.F. POWER AMPLIFIER2.7 R.F. POWER AMPLIFIER2.7 R.F. POWER AMPLIFIER2.7 R.F. POWER AMPLIFIERThe final power stage is mounted on a heat sink to dissapate waste heatand is enclosed in a totally screened, metal container, fixed to theupper-middle part of the central section of the unit (1 Fig.5). The RFsignal coming from the Stereo Decoder or Mono\MPX at a power level ofabout 300 mW, reaches the driver stage (BGY33) and is amplified to alevel from about 1W to 20 W before being further amplified by the finalstage (two MRF317 or two SD1480) to a level of upto 150 W. The resultantsignal is then filtered by a low-pass filter (2 Fig.5) which removesany harmonic content.A directional coupler allows the direct andreflected power levels to be measured and displayed on the analogmultimeter and also fedback to the power supply for automatic controlof the output power (see Power Supply description). A BNC connectorsituated on the rear panel provides a power signal at -40 dB of theamplifier output power.2.8 METER CARD2.8 METER CARD2.8 METER CARD2.8 METER CARD2.8 METER CARDThis card is situated centrally on the front panel (5 Fig.4 and 7 Fig.5).The card receives direct and reflected power signals from the powersupply which, in turn, come from the final power stage. The Stereoencoder card supplies deviation and left and right signal levels.These signal levelsare then displayed on the analog meter according tothe position of therotary selector situated on the front panel.2.9 CONTRAVES CARD2.9 CONTRAVES CARD2.9 CONTRAVES CARD2.9 CONTRAVES CARD2.9 CONTRAVES CARDThis card is fixed to the left-hand side of the front panel (5 Fig.5).The operating frequency selected by the frequency control is representedby a signal which is supplied to the frequency dividers that form partof the PLL circuits found on the PLL card.2.10 ALARMS CARD2.10 ALARMS CARD2.10 ALARMS CARD2.10 ALARMS CARD2.10 ALARMS CARDThis card is fixed in the lower part of the unit (7 Fig.4). This circuitallows to adjust, through 7 trimmers, the threeshold of the externaland internal output level, internal and external VSWR level, temperatureand to preset the maximum value of the output power. In case of faultthere isn't an automatic reset, because the transmitter provides todecrease the output power to continue the transmission withoutstops,even if at minimum power.

The two figures to the right of the decimal point rep-resent (from left to right) hundreds of KHz and tens of KHz.Eg: 098.45 = ninety eight megahertz and four hundred and fiftyKilohertz.Eg: 103.94 = one hundred and three Megahertz and nine hundred and fortyKilohertz.Furthermore, if a frequency is selected beyond the two limits of the87.5-108 MHz band, the amplifier will continue to work even through thedisplayed frequency no longer corresponds to the operating frequencyof the unit.Note: Transmitting outside the legal band (87.5-108 MHz) is an offenceNote: Transmitting outside the legal band (87.5-108 MHz) is an offenceNote: Transmitting outside the legal band (87.5-108 MHz) is an offenceNote: Transmitting outside the legal band (87.5-108 MHz) is an offenceNote: Transmitting outside the legal band (87.5-108 MHz) is an offenceand may lead to prosecution.and may lead to prosecution.and may lead to prosecution.and may lead to prosecution.and may lead to prosecution.8)After having verified that the UNLOCK led is switched off and thatthe unit is therefore locked to the selected operating frequency, switchthe switch connected to the REMOTE connector so as to remove the shortcircuit between the central conductor and ground. The RF output is nowenabled and should correspond to a power level of about 10W. To checkthis reading, select FWD on the meter selector and read the power fromthe 200 W FSD scale.9)Using a small screwdriver, rotate the PWR ADJ control clockwise; thepower output should increase progressively to a maximum of 100W.Check the value with the bypass wattmeter which should be within ±10%.
XT150 and XT150S Technical and Maintenance ManualPag. 2610)With the power output at 150W, select a new operating frequency wellaway from the current value. Eg: 107 MHz: the UNLOCK led should switchon and the power output should fall to zero at the same time. Only whenthe UNLOCK led switches off (unit locked to new frequency) should thepower output resume its previous level.11) Automatic power control checkIt is advisable to start this procedure with the operating frequencyset to 87.50 MHz. When locked to this frequency, the PWR ADJ controlshould be adjusted for an output power of 50 W. Now, with no furtheradjustment of the PWR ADJ control, change the operating frequency insteps of 4-5 MHz, ensuring that the output power remains constant at50 W.12) SWR alarm checkFor this test, adjust the PWR ADJ control for a power output of 10W.Disconnect the output load and check that the S.W.R. led switches on.Now adjust the PWR ADJ control to check that the unit switches on againat a reflected power level of about 20 W. Turn the PWR ADJ control formaximum power and check that the reflected power does not exceed 50 W.Re-connect the output load and check that REF falls to zero, the SWRled switches off and that PWR FWD jumps to 150 W.13) Now short circuit the central conductor of the REMOTE input to groundand the output power should drop instantly to zero. Removing the shortshould cause the power output to return, gradually, to its previouslevel.14) Deviation reading checkThe maximum input sensitivity is determined by the position of the INPUTLEVEL control. In the -12/+9 position, the sensitivity will d e -pend on the L/mpx and R/mono controls. Put the selector in the DEVposition. Connect a low-distortion audio generator to the LEFT and RIGHTinputs. Inject a 400 Hz tone at a level of 0dBm (775mVRMS= 2.2Vpp).Put theINPUT LEVEL control in the 0dBm position. Select stereo mode (thecorresponding led will switch on). Enable the PILOT using the relevantswitch (the green led will switch on). With the selector in the R/MONOposition, check that the reading is 0b, measured on the +3dB FSD scale.Repeat the operation for the L/MPX. Check that the deviation readingis 100%.3.33.33.33.33.31) Inject the pilot tone checking that the corresponding led switcheson.3.43.43.43.43.4 OPERATION USING THE INTERNAL STEREO ENCODER (Only for Stereo Ver.)OPERATION USING THE INTERNAL STEREO ENCODER (Only for Stereo Ver.)OPERATION USING THE INTERNAL STEREO ENCODER (Only for Stereo Ver.)OPERATION USING THE INTERNAL STEREO ENCODER (Only for Stereo Ver.)OPERATION USING THE INTERNAL STEREO ENCODER (Only for Stereo Ver.)1) Inject the pilot tone checking that the corresponding led switcheson.
