The SE Series Dual transmitter system features a completely redundant RF power, Monitor and Control structure. With dual Transmitter Control microprocessors and dual RF power sections there is always a secondary system in standby mode to assume operation should a failure occur in the primary system. A third microprocessor, the Master Control, serves as the system’s user interface via a key pad, LCD and embedded Ethernet server. The Master Control also monitors the status of the primary transmitter and forces a shutdown and subsequent transfer under faulty conditions, which enables the secondary system to continue seamless operation. 2. The SE Series transmitter also features a DC power backup to provide seamless operation should the primary AC voltage source experience a brown out or lose power. A DC Auto Disconnect protects the external batteries should they reach a critically low value. Safety: 1. The SE Series transmitter has been designed, manufactured and tested in order to offer a safe working environment in both normal and degraded modes of operation. This is primarily achieved through system design and manufacturing to the health and safety requirements contained in “Safety of information technology” IEC 60950:1999. Safety designs include proper grounding to reduce shock hazards, danger labels in appropriate areas and descriptions of hazards and warnings in the User’s Manual. 2. Specifically the SE Series Transmitter was tested by Retlif Testing Laboratories per the requirements of the Low Voltage Directive 73/23/EEC. Under 73/23/EEC the SE Series Transmitter was reviewed to the safety requirements of EN 60950-1, EN 60950-22 and EN 60945.

The SE Series Transmitter utilizes an outside enclosure rated to Ingress Protection (IP) 66, which was tested to the international standard IEC 60529 Edition 2.1, 2001-02. 3. The SE Series Transmitter is intended to be used in ambient temperature conditions between -30 and +70 degrees Celsius. 4. The SE Series Transmitter is intended to be used in a non condensing relative humidity environment with humidity ranging from 0 to 95%. 5. The IP66 rated SE Series Transmitter is suitable for use in high salinity environments as encountered in offshore conditions.6. The SE Series transmitter should not be used above 10,000 feet (3048 meters). Principles governing the logical architecture of systems: 1. The SE Series Transmitter system is designed on a fully redundant platform based on an architecture used by Southern Avionics Company, which has been sold in the EU for many years. As an option the SE Series design employs an embedded server using an Ethernet protocol for ease of local and remote interface via Ethernet or the Internet.Description of Procedure followed in order to declare suitability of use Principles governing the construction of systems: 1. The SE Series Transmitter is designed to maximize modularity of critical printed circuit boards in both the Master Control and RF Transmitter sections. This concept allows the fastest upgrade of failed boards without the need for special tools. The design also affords high availability due to its solid-state design and full system redundancy.

SOUTHERN AVIONICS COMPANYSE125 Installation and Setup 4-1Master Control Panel Description4 Master Control Panel Description The Master Controller Panel is the main control panel for the SE series transmitters. Thefollowing gives directions on how to operate the SE transmitter using the Master Controller Panelkeypad. The Master Controller keypad consists of 30 keys, 23 LEDs, a 4 line by 40 characterLCD display and dual analog meters.SDE33011 Rev AFigure 4-1. SE Master Control Panel
SOUTHERN AVIONICS COMPANYSE125 Installation and Setup4-2 Master Control Panel Description4.1 MetersThe upper analog meter monitors the following three functions•Forward Transmit Power - Indicates how much radio frequency transmit power the SEtransmitter is sending to the ATU•Reflected Transmit Power - Indicate how much, of the forward power, is being reflectedback to the transmitter from the ATU because of mismatches in the antenna impedance•Modulation - Indicates the modulation index The lower analog meter monitors the following two functions•Power Amplifier Voltage (PAV) - This gives an indication of the voltage applied to the finalFETS in the Switching Power Amplifier•Power Amplifier Current (PAI) - This gives an indication of the current flowing through thefinal FETS in the Switching Power AmplifierTaking these two values and multiplying them together will give an indication of the power input tothe final FETS.SPA Power Input = PAV * PAIThe efficiency of the Switching Power Amplifier is calculated by taking the forward transmit powerfrom the upper meter and dividing this number by the calculated SPA power input to the finalFETS.Efficiency (%) = (Forward Transmit Power)/(SPA Power Input) * 100%4.2 Keys/LEDsFrequency Key (FREQ) - This key sets the transmitting frequency of the transmitter. Thetransmitter can be set to the desired frequency by pressing the FREQ key, then entering thedesired frequency using the numeric keys and then pressing the ENTER key. Although thetransmitter can cover any frequency from 190.0 KHz to 1800.0 KHz, the Filter/Monitor modulemust be configured for the desired frequency.Tone Key (TONE) - This key sets the tone frequency of the Identifier. The frequency can betoggled to either 400 Hz or 1020 Hz using the tone key.
SOUTHERN AVIONICS COMPANYSE125 Installation and Setup 4-3Master Control Panel DescriptionCall Sign Key (Call Sign) - This key allows the user to enter the identifier of the station. Analphanumeric identifier up to 8 characters may be used. The default call sign is "SAC". Usingthe numeric part of the keypad, the user may enter the identifier. This type of entry is identical totext messaging on a cell phone. To begin this procedure, the operator presses the call sign key.The present call sign, if present, will clear to all blanks. The most significant character is enteredfirst. For example, by pressing the "1" key the first time produces an “A” for the character.Pressing the key again, changes the character from an “A” to a “B”. If the user continues to pressthe "1" key, they would see the character "C" next, then the number "1", and then the character"A" again. To keep the desired character, wait for 2 seconds and the character place will shiftover. This process continues until the entire identifier is in place. The user presses the enter keyand the identifier is stored into memory. An example of this procedure is as follows for anIdentifier “SAC”. The user would perform the following:•press "CALL SIGN" key•press the "7" key once•wait 2 seconds•press the "1" key once•wait 2 seconds•press the "1" key 3 times•wait 2 seconds•press "Enter" key.This completes the operation.Mode Key (MODE) - This key toggles between 3 modes of operation the SE transmitter willoperate in. They are as follows:•Ident - In this mode the transmitter will send out the identifier of the transmitter. Thisprocess repeats continuously.•CARR - In this mode, the transmitter simply sends out a dead carrier with no modulation.•CONT. - In this mode, the transmitter sends out a continuous tone.Output Power -This key sets the RF output power of the transmitter. Press Output Power, entera power level between 0 and 125 Watts and then press Enter.Modulation Level (Mod Level) - This key sets the amplitude modulation level of the transmitter.Press Mod Level, enter a modulation level between 50% and 100%, and then press Enter.Alert Tone - This key turns an audio alert tone ON or OFF. An LED (Alert Tone ON) on the lefthand side of the keypad indicates the status of Alert Tone.
SOUTHERN AVIONICS COMPANYSE125 Installation and Setup4-4 Master Control Panel DescriptionDO NOT PRESS THIS KEY WITHOUT CONNECTING A DUMMY LOAD ON THEOUTPUT OF THE TRANSMITTER NOT CURRENTLY OPERATING. DOING SO WILLDAMAGE THE COAXIAL RELAY AND POSSIBLY ONE OR BOTH TRANSMITTERS. Test Mode - This key allows both transmitters to operate at the same time. This mode is fortroubleshooting one transmitter while the other transmitter is still on the air. AN LED (TX1TX2ON) on the left hand side of the keypad indicates whether both transmitters are activated.Special Function (SPCL FCTN) - This switch is discussed under the special function section4.3 on page 4-5.LCD DATA - This switch allows the user to select the type of data that is seen on the LCDDisplay whether it is operating parameters or special parameters including observed frequency,modulation index, forward and reflected power. The LED's (TX1 TX2) below this switch indicatewhich transmitter the data relates to.UP/DWN Switches above LCD Data - These switches allow the user to scroll up and downthrough the data observed or data selections.Main TX Select (Main TX) - This switch allows the user to select which transmitter is selected asthe main transmitter - TX1 or TX2. The LED's (TX1 TX2) above the switch indicate which TX isselected.Monitor Enable (Enable) - This switch enables the transmitting monitoring circuitry. Thisfunction monitors for a number of faults. These are: VSWR, Power, Continuous and No Tone.RF Meter Select - This switch toggles through forward power, reflected power and modulationindex indicating which parameter is currently being viewed on the RF meter. An LED indicatesthe selected parameter.PA Meter - This switch toggles between PA voltage and PA current indicating which parameter isdisplayed on the PA meter. An LED indicates the selected parameter.4.2.1 Alarm Conditions:VSWR Overload - This alarm occurs when the VSWR exceeds a preset limit.Power Output OVER/UNDER - This alarm occurs when the output power either goes below orabove the preset limits set in the transmitter.No Tone - This alarm occurs if the monitoring circuitry detects a No Tone Condition where thetransmitter is producing a dead carrier.Continuous Tone - This alarm occurs when the monitoring circuitry detects a continuous toneand not an identification sequence or low modulation (<70%).These alarms are indicated by LED’s for each transmitter in the upper middle of the keypad.These are indicated by
SOUTHERN AVIONICS COMPANYSE125 Installation and Setup 4-5Master Control Panel DescriptionV = VSWR, P = Power, N = No Tone, and C = Continuous ToneThese alarms will cause a transmitter transfer in the case of a dual transmitter and a transmittershutdown in the case of a single. Two other alarms that are indicated on the LCD, but not by LED, areObserved Frequency - This alarm occurs when the built in frequency counter detects themeasured frequency is out of tolerance with the desired frequency.Incorrect Identification - This alarm occurs when the monitoring circuitry detects a differentIdentifier from the desired Identifier. The LED's above the monitor enable switch indicate thepresent status of the transmitters. The PRI LED indicates the primary transmitter selected by themain TX select key is the operating transmitter. The SEC LED indicates failure in the Primarytransmitter and the monitoring circuitry has commanded the transmitter to switch to thesecondary transmitter. The fail LED indicates that both transmitters have failed and the systemhas shut down. When testing the SE transmitter, Monitor Enable must be turned OFF.4.3 Special Functions on the (SPCL FCTN) KeyAll Functions are SPCL FCTN Key + NumberSPCL FCTN +1This function stores all data into the onboard EEPROM. Once data is stored, the transmitter willcome back to the original settings if AC and DC power are lost. SPCL FCTN +5This function configures the Remote Control Unit.SPCL FCTN +6This function is a special test mode. In this mode the Master Controller will test for improperidentification. The Master Controller commands the Transmitter Control to add 32 to the asciivalue of every ID chararter. After the transmitter changes identification, it is still sending backdata on all of the parameters associated with that transmitter including identification. Once theidentification changes, the Master Controller will institute a transmitter changeover and shutdownof the offending transmitter.SPCL FCTN +7This function is a special test mode. In this mode, the Master Controller will test for under powershutdown. The Master Controller commands the Transmitter Controller to decrease the outputpower by over 50%. As the transmitter changes power level, it is still sending back data on all ofthe parameters associated with that transmitter. Once the power level drops below anacceptable level, the Master Controller will institute a transmitter changeover and shutdown ofthe offending transmitter.
SOUTHERN AVIONICS COMPANYSE125 Installation and Setup4-6 Master Control Panel DescriptionSPCL FCTN +8This function calibrates the modulation power, antenna current and frequency for eachtransmitter. This offset compensates for the error that exists between the Transmitter Controldigital to analog converter and the measured output. SPCL FCTN +9This function configures the DCAD or network for SE systems. SPCL FCTN +0 (Software not available at this time)This function puts the Master Controller into a logging mode. It stores all pertinent data for agiven interval. SPCL FCTN + “Down Arrow Key” (Software not available at this time)This test function tests the linearity of the forward/reflected power and modulation meter. Firstthe Master Controller commands the Transmitter Control to increase the RF output power inincrements of 5 Watts starting at 10 Watts and increasing to 125 Watts. It then reverses anddecreases by 5 Watts until the transmitter returns to 10 Watts output. It then will start increasingthe modulation level by 5% from 0 to 95%. The modulation then returns to 0% and the unit goesback to power increase and decrease.

SOUTHERN AVIONICS COMPANYSE125 Installation and Setup 9-15Coupler Setup9.4 Antenna TheoryThe range of a beacon and antenna depends on many variables and cannot be guaranteed. Thefield strength can be calculated if the ground conductivity is known, but the field strength neededdepends on background environmental noise which depends on location. A field strength of70uV/m is generally adequate in the United States and Europe but may not be sufficient inlatitudes between 30 degrees N and 30 degrees S.9.4.1 Symmetrical “T” AntennaA Symmetrical “T” Antenna is recommended for use with a 125 - 250 Watt transmitter if sufficientland is available. This antenna requires a plot of ground approximately 150 feet by 400 feet for a60 foot high antenna to 150 feet by 500 feet for a 120 foot high antenna.The standard Symmetrical “T” Antenna is supported by 60 foot above ground level towers orpoles placed 300 feet apart and has a 55 foot vertical radiator and a 2 wire 280 foot horizontal tophat. Range depends on the field strength required, the ground condition, and the power radiated.The power radiated increases with frequency, however, the propagation loss due to groundcondition decreases with frequency. For a 70 uV/m field strength, the range over “good” groundvaries from approximately 60 miles at 190 KHz to 70 miles at 535 KHz with a 50 watt transmitterand approximately 80 miles at 190 KHz to 90 miles at 535 KHz with a 100 watt transmitter.A Symmetrical “T” Antenna supported by 90 foot towers has a 85 foot vertical radiator and a 2wire 280 foot horizontal top hat. Range with this antenna over “good” ground varies fromapproximately 90 miles at 190 KHz to 95 miles at 535 KHz with a 50 watt transmitter and fromapproximately 105 miles at 190 KHz to 115 miles at 535 KHz with a 100 watt transmitter.9.4.2 Tower AntennaA Tower Antenna can be used if sufficient land is not available for a Symmetrical “T” Antenna. Aportion of the top set of guy wires is used to form the top hat for this antenna. A Tower Antennais electrically inferior to a Symmetrical “T” Antenna of the same height due to the decreased toploading. Top loading serves two purposes; decreasing the input reactance and consequently thevoltage on the antenna and increasing the effective height.A 50 foot tower requires a plot of ground with a radius of 60 feet. Range over “good” groundvaries from approximately 40 miles at 190 KHz to 50 miles at 535 KHz with a 50 watt transmitterand from approximately 60 miles at 190 KHz to 65 miles at 535 KHz with at 100 watt transmitter.

SOUTHERN AVIONICS COMPANYSE125 Installation and Setup 10-110 Antenna Tuning and Matching for PC1000C/3 The objective of this section is to setup the coupler to present a 50 Ohm, minimally reactive loadto the SE Transmitter. To ensure this, the inductance of the coupler should be adjusted so thatthe measured PA current and voltage matches the values recorded in step 7.5.11 on page 7-3 asclosely as possible.10.1 The SE Series transmitter is shipped with the default turn on power output set to Zero Watts. Ifthe power output has been changed, then connect the SE Transmitter’s RF output to a dummyload.Turn the system ON and verify that:TX1 is set as Primary transmitter The MODE is set to CARRThe OUTPUT POWER is set to Zero (0) watts into a DUMMY LOAD.MONITOR is disabled10.2 After verification, connect the Transmitter RF output coax to the Coupler’s input RF N connector.(It is assumed here that the coupler control cable has already been connected to the SETransmitter according to installation instructions.)10.3 On the coupler front panel, set the Sense and Speed controls fully clockwise temporarily.10.4 Set the RF Power Level to approximately 20 Watts, making sure the Coupler TX ON/OFF switchis ON.10.5 Check the Reflected Power reading to determine the antenna’s state of tune. A value of 0, ornearly 0, indicates the antenna is tuned. If it is tuned, go to step 10.10 on page 10-2 to ensure thatthe best tap combination has been selected. If not, continue to step 10.6 on page 10-2.
SOUTHERN AVIONICS COMPANYSE125 Installation and Setup10-210.6 Rotate the coupler’s INDUCTANCE from one limit to the other by using the CCW/CW switchwhile in manual mode. Monitor the coupler meter tune reading during this process for a change inreflected power. If a change is seen, place the switch in auto to allow the Autotune to makeadjustments freely and go to step 10.7 on page 10-2.10.7 Turn the Coupler TX ON/OFF Switch OFF, change the FINE TAPS selector wire to the next lowersetting and repeat step 10.4 on page 10-1 through step 10.6 on page 10-2. If the antenna doesnot tune, change the FINE TAPS selector wire to the next higher setting and repeat step 10.4 onpage 10-1 through step 10.6 on page 10-2. Continue this bracketing procedure until theAutotune motor starts to tune the antenna.If the FINE TAPS selector is at its lowest setting and it is necessary to decrease the inductance,change the Coarse Tap to the next lower tap and change the FINE TAPS selector to the highestsetting. If the FINE TAPS selector is on the highest setting and it is necessary to increase theinductance, change the Coarse Tap to the next higher tap and change the FINE TAPS selector tothe lowest setting. Due to overlap, it may be necessary to change the FINE TAPS selector a fewpositions before the inductance will be the same as it was before the Coarse Tap was changed.10.8 Set the RF Power Level to the transmitter’s maximum rated level. Verify the measured ForwardPower level agrees with this setting. Adjust the Coupler’s front panel Sense controlcounterclockwise for autotune stability as necessary. It will be fine set later in this procedure.10.9 Record the measured Reflected Power level and, then ,turn the Coupler TX ON/OFF SwitchOFF.10.10 Increase the coupler’s IMPEDANCE selector wire setting by one position, the, turn the CouplerTX ON/OFF Switch ON. Set the RF Power Level to the transmitter’s maximum rated level, andverify the measured Forward Power level agrees with this setting.10.11 Record the current measured Reflected Power level and compare it with the level recorded instep 10.9 on page 10-2. If the current level is greater than the recorded level, turn the CouplerTX ON/OFF Switch OFF and decrease the IMPEDANCE selector wire setting by two positionsthen turn the Coupler TX ON/OFF Switch ON. If the current level is less than the recorded level,
SOUTHERN AVIONICS COMPANYSE125 Installation and Setup 10-3turn the Coupler TX ON/OFF Switch OFF and increase the IMPEDANCE selector wire setting byone position.10.12 Repeat step 10.9 on page 10-2 through step 10.11 on page 10-2 until the IMPEDANCE selectorsetting is found that gives the lowest Reflected Power level and results in a PA current andvoltage close to that recorded in step 7.5.11 on page 7-3.Normal voltage and current readings at 50 Ohms for each specific transmitter can be found in thetransmitter’s Factory Acceptance Test (FAT) procedure.10.13 Set the transmitter to operate in Morse Code Identifier (IDENT) Mode.10.14 Adjust the sense adjustment potentiometer on the coupler Autotune PCB counter clockwise(CCW) until the Autotune motor begins to chatter, then adjust it back clockwise until all chatteringstops.10.15 Reduce the Output Power to 0.10.16 Turn the transmitter OFF (Switch the AC and DC switch to the OFF position.)10.17 Remove the coupler’s RF output lead where it is attached to the coil.10.18 Remove the clip from the lead end and trim the wire to the proper length. Ensure at least 3in(7.6cm) separates the wire from both the coil and the coupler enclosure.10.19 Dress the wire to avoid sharp bends that may lead to high voltage corona discharge, and solderthe lead to the selected coarse tap on the coil.

SOUTHERN AVIONICS COMPANYSE125 Installation and Setup 12-1Optional Equipment12 Optional Equipment 12.1 Audio - SLP1002012.1.1 General DescriptionThe Audio PCB is an OPTIONAL addition to the standard system which allows the user tobroadcast AWOS announcements. The option is implemented as a daughter board to the DigitalI/O PCB and consists of four sections as follows:•Audio Input Amplifier•Automatic Gain Control (AGC)•Chebyshev Passband Filter•Voice DetectorThe Voice amplifier takes the nominal -17 dBm signal level and amplifies it to a level usable bythe AGC section. The amplifier is common mode balanced with adjustable gain.The AGC circuit is responsible for modulation limiting. It is adjusted to "capture" the level at -17dBm and output a constant modulation level to the Digital I/O PWM section up to levelsexceeding +10 dBm. This section prevents inadvertent over modulation of the voice signal. It isnecessary since the Controller has no control over user input.The Chebyshev Passband filter is designed for 300 to 3000Hz. The output at 4000Hz is downmore than 45 dB, ensuring any out of band audio signals from the operator will not causeadjacent channel interference.The Voice Detector has two functions. It detects the presence of an announcement sequenceand automatically attenuates the keying tone level down to 20% modulation. The announcementlevel is summed with the keying tone level and set to achieve 95% composite modulation. Thisaction prevents over modulation and allows the announcement to be heard over the beaconMorse code IDENT tones. The Voice Detector signals the Controller to temporarily suspendmodulation alarms, since the IDENT tone level is dropped below the alarm threshold.12.1.2 Detailed Circuit AnalysisGeneral OperationThe Audio PCB is an option that plugs into the Digital I/O PCB allowing an externally appliedsignal, usually AWOS, to modulate the transmitter. The plug in provides amplification, automaticgain control, audio pass-band filtering, and input detection and control.
SOUTHERN AVIONICS COMPANYSE125 Installation and Setup12-2 Optional EquipmentInput AmplifierThe input differential amplifier takes a 600 Ohm or high impedance input depending on thesetting of JP1 and is made up of U2A, U2B, and U3A.VOICE+ and VOICE- come in through R7, C5 and R21, C10 to develop a balanced voltage dropacross R13 and R18. R8 and R22 couple this voltage to U2A and U3A. R15, R19, andpotentiometer R24 provide common mode rejection to be fine tuned for minimal line noise. JP2is used when making this adjustment, and R16 and R25 set the gain of this stage. U2B, alongwith the C7, R17 network, and R20, C10 network, provide a flat audio band response. Theoutput of this stage continues on to the AGC circuitry.AGC section The signal AGC_IN is coupled via network C14, R27, and C15 to input calibration potentiometerR26 where it is coupled, via C16 and R30, to U1C. R28, R33, C18, and R29 provide midpointbias for U1C whose gain is set by R36, C21 and R38, C25. A sample of this signal is fed via C22to AGC circuit U1C, Q2, Q3, and Q4. Q12 acts as a variable resistor at the input of U2A, U1C.The resistance is controlled by the signal level fed back from U1C pin 1. As the signal levelincreases, the gate voltage on Q2 decreases and the resistance decreases, thus lowering theaudio input level to U1C pin 10 and holding the average audio output level constant. U1D booststhe level of the audio signal, which is output through modulation level adjustment potentiometerR31 and C19 as VOICE_FLTR_IN. A constant level output is also sent toVOICE_DETECTOR_IN.Pass-band Filter section VOICE_FLTR_IN is coupled into a Chebyshev active pass band filter consisting of U4, U5, andassociated components. Its low end 3dB roll off point is 300Hz, and its high end 3dB roll off pointis 3000Hz, with sufficient attenuation to meet or exceed FCC requirements. The detailed theoryof operation of multi-stage active filters is beyond the scope of this manual and best left to atextbook on the subject. The output of this stage is called VOICE_FLTR_OUT.Voice Detector SectionThe voice detector’s purpose is to notify the Controller that a voice announcement sequence isbeginning. This process automatically attenuates the normal IDENT output to allow clearreception of the message and prevents over modulation. A sample of the AGC output is routedas VOICE_DETECTOR_IN via C2 to buffer U1A. CR1 and C3, R4 convert the audio to a DClevel. When this level is enough to over come the bias on U1B pin 6, the output goes highcausing Q1 to virtually short one end of potentiometer R2 to ground. The adjustable leg of thepotentiometer leaves the board as VOICE_DETECT and connects to the TONE input line on theDigital I/O PCB. Therefore, R2 becomes a shunt to ground, which is adjusted to lower the tonelevel appropriately when an AWOS announcement is input. Buffer U3B provides an additionallevel shifted output called VOICE_ON, which notifies the Controller external modulation is beingapplied.
