Description of the constituent
Southern Avionics Company’s SE series Transmitters with PC1000C/3, PC1000M/3,
PC1000H/3 or PC3000 Antenna Tuning Units (ATU) and Remote Control Unit (RCU)
have been designed and tested to operate as a standalone Non Directional radio Beacon
system for airplane navigation as part of the Air Traffic Management network. The SE
series Transmitter may also be used as an Inner or Outer Marker Beacon utilized during
an aircraft’s approach to land. This system has been designed to operate on land,
offshore platforms or maritime vessels. The system develops an output power of 10-125
Watts (SE125) or 50-250 Watts (SE250) with a frequency range of 190kHz to 1250kHz.
The system is intended to operate up to an Amplitude Modulation level of 100% while
communicating an alpha numeric Morse Code identifier via on/off keying. The
transmitter’s input voltage requirements are 100-264VAC at 47-63Hz or 48VDC. The
ATU’s operating voltage, +12VDC, is provided by the SE Transmitter or local power
supply. The RCU’s input voltage requirement is +12VDC provided by a wall mounted
power supply or a customer provided +12VDC backup.

Description of Procedure followed in order to declare suitability of use
Self Declaration to Essential Requirements
Seamless Operation:
1. 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 workin
g
environment in both normal and de
g
raded 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.

Description of Procedure followed in order to declare suitability of use
Self Declaration to Essential Requirements (continued)
Environmental Constraints:
1. The SE Series Transmitter meets or exceeds the requirements of 2002/95/EC on
the restriction of the use of certain hazardous substances in electrical and
electronic equipment. Design and construction to the requirements of this directive
minimizes or eliminates the concentration of lead, mercury, cadmium, hexavalent
chromium, polybrominated biphenyls or polybrominated diphenyl ethers used in
the SE Series Transmitter system.
2. 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.

1Introduction
The SE Series transmitters are computer controlled systems designed around an embedded
microprocessor. These systems are capable of remote monitoring and maintenance via Ethernet
(optional).
All aspects of transmitter setup and operation, with the exception of main power application,
come under the direct control of the Controller/Monitor. Setup and control of the Transmitter is
performed at the local control panel or by a separate personal computer (PC)/laptop connected
locally or remotely via Ethernet. Options are available for control remotely using phone lines or
other carrier, which can handle leased line or dial up modems. The PC or laptop uses custom
software to generate a graphical user interface (Web Watch) which allows monitoring of system
parameters and provides setup and control of the following:
•Direct Digital Synthesis (DDS) generated RF carrier frequency and Audio Tone
Frequencies
•Identifier Morse Code (up to eight (8) characters or numbers)
•Standard alarms, view and reset
•Additional fault handling based on multipoint voltage, current, and temperature monitoring
•Transfer criteria (dual transmitter only)
•Power levels
•Modulation levels
An optional Remote Control Unit (RCU) is available which uses RS-485 communication lines
between it and the transmitter. The RCU allows full monitoring and basic control of the
transmitter from up to 4000ft (1220m) away.

1.2 Model SE125 General Description
The SE series non-directional beacon is a microprocessor controlled Amplitude Modulated (AM)
transmitter with output power adjustable from 10 - 125 Watts. The radio frequency (RF) section uses
field effect transistor (FET) switching technology in the power amplifier (PA), modulator, high voltage
(HV) and low voltage (LV) regulator modules resulting in a highly efficient system.
The front control panel utilizes membrane switches and an easy to view 40 line by 4 character
LCD with white characters on a blue background. Front panel controls include Desired Carrier
Frequency, Tone Frequency, Call Sign/Identifier, Output Power, Modulation Level, Main
Transmitter select, Mode of Operation, Monitor Enable, and controls for monitoring critical
transmitter parameters and test modes.
The Master Control and Transmitter Control sections utilize the Renesas M16C/29 microprocessor,
which was designed specifically for efficient embedded systems. The Transmitter Control utilizes
modern direct digital synthesis (DDS) technology to create the precision audio and radio frequencies
needed by the RF section. Beacon operation is program controlled and monitored. Most of the
operational parameters are user-definable thus facilitating customized equipment configurations.
Using an Ethernet connection, the user has complete control of the SE transmitter. In addition, a
personal computer (PC) running an Internet Browser and connected to the Transmitter’s IP address
can communicate with, configure, and monitor the system.
SOUTHERN AVIONICS COMPANY
SE125 Installation and Setup1-14 Introduction
All standard fault conditions such a Low Power, No-Tone, VSWR, and Continuous Tone are
monitored. Additional fault conditions designed to protect the equipment are reported via an interrupt
request (IRQ) to trigger an immediate response from the controller.
Other important system parameters such as PA current, PA voltage, AC and DC current and voltage,
high voltage, and RF current are also monitored.
RF frequency is monitored with an independent counter and is correctable beyond the stated base
frequency accuracy. RF Power and Modulation percentage readings are also corrected to yield near
test equipment quality measurements.
System configuration includes discreet control Morse Code entry as well a maximum of eight (8)
character ID sequences. Dual system operation is available in a totally redundant system including
two independent Transmitter Controllers, RF sections and Power Supplies.
Optional emergency battery power is supported with battery voltage and both charge and discharge
current being monitored. The DC automatic disconnect (DCAD) feature, which protects the battery
stack from excessive discharge, is user-definable, and allows the system to be optimized for whatever
battery type the user chooses.
Optional automated weather observing system (AWOS) voice operation is supported with
automatic gain control (AGC) ensuring proper operation over a wide range of user inputs. Band
pass filtering limits the audio output to satisfy Federal Communications Commission (FCC)
bandwidth requirements.
The transmitter is provided in an IP66 rated enclosure or a 19 inch rack mountable
configuration.
Qualifications: Transmitter is designed to meet applicable requirements of International Civil
Aviation Organization (ICAO), Federal Communications Commission (FCC), Federal Aviation

SE125 Installation and Setup 4-1Master Control Panel Description
4 Master Control Panel Description
The Master Controller Panel is the main control panel for the SE series transmitters. The
following gives directions on how to operate the SE transmitter using the Master Controller Panel
keypad. The Master Controller keypad consists of 30 keys, 23 LEDs, a 4 line by 40 character
LCD display and dual analog meters.
SDE33011 Rev A
Figure 4-1. SE Master Control Panel
SOUTHERN AVIONICS COMPANY
SE125 Installation and Setup4-2 Master Control Panel Description
4.1 Meters
The upper analog meter monitors the following three functions
•Forward Transmit Power - Indicates how much radio frequency transmit power the SE
transmitter is sending to the ATU
•Reflected Transmit Power - Indicate how much, of the forward power, is being reflected
back 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 final
FETS in the Switching Power Amplifier
•Power Amplifier Current (PAI) - This gives an indication of the current flowing through the
final FETS in the Switching Power Amplifier
Taking these two values and multiplying them together will give an indication of the power input to
the final FETS.
SPA Power Input = PAV * PAI
The efficiency of the Switching Power Amplifier is calculated by taking the forward transmit power
from the upper meter and dividing this number by the calculated SPA power input to the final
FETS.
Efficiency (%) = (Forward Transmit Power)/(SPA Power Input) * 100%
4.2 Keys/LEDs
Frequency Key (FREQ) - This key sets the transmitting frequency of the transmitter. The
transmitter can be set to the desired frequency by pressing the FREQ key, then entering the
desired frequency using the numeric keys and then pressing the ENTER key. Although the
transmitter can cover any frequency from 190.0 KHz to 1800.0 KHz, the Filter/Monitor module
must be configured for the desired frequency.
Tone Key (TONE) - This key sets the tone frequency of the Identifier. The frequency can be
toggled to either 400 Hz or 1020 Hz using the tone key.
SOUTHERN AVIONICS COMPANY
SE125 Installation and Setup 4-3Master Control Panel Description
Call Sign Key (Call Sign) - This key allows the user to enter the identifier of the station. An
alphanumeric identifier up to 8 characters may be used. The default call sign is "SAC". Using
the numeric part of the keypad, the user may enter the identifier. This type of entry is identical to
text 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 entered
first. 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 press
the "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 shift
over. This process continues until the entire identifier is in place. The user presses the enter key
and the identifier is stored into memory. An example of this procedure is as follows for an
Identifier “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 will
operate in. They are as follows:
•Ident - In this mode the transmitter will send out the identifier of the transmitter. This
process 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, enter
a 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 left
hand side of the keypad indicates the status of Alert Tone.
SOUTHERN AVIONICS COMPANY
SE125 Installation and Setup4-4 Master Control Panel Description
DO NOT PRESS THIS KEY WITHOUT CONNECTING A DUMMY LOAD ON THE
OUTPUT OF THE TRANSMITTER NOT CURRENTLY OPERATING. DOING SO WILL
DAMAGE 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 for
troubleshooting one transmitter while the other transmitter is still on the air. AN LED (TX1TX2
ON) 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 section
4.3 on page 4-5.
LCD DATA - This switch allows the user to select the type of data that is seen on the LCD
Display 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 indicate
which transmitter the data relates to.
UP/DWN Switches above LCD Data - These switches allow the user to scroll up and down
through the data observed or data selections.
Main TX Select (Main TX) - This switch allows the user to select which transmitter is selected as
the main transmitter - TX1 or TX2. The LED's (TX1 TX2) above the switch indicate which TX is
selected.
Monitor Enable (Enable) - This switch enables the transmitting monitoring circuitry. This
function 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 modulation
index indicating which parameter is currently being viewed on the RF meter. An LED indicates
the selected parameter.
PA Meter - This switch toggles between PA voltage and PA current indicating which parameter is
displayed 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 or
above the preset limits set in the transmitter.
No Tone - This alarm occurs if the monitoring circuitry detects a No Tone Condition where the
transmitter is producing a dead carrier.
Continuous Tone - This alarm occurs when the monitoring circuitry detects a continuous tone
and 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 COMPANY
SE125 Installation and Setup 4-5Master Control Panel Description
V = VSWR, P = Power, N = No Tone, and C = Continuous Tone
These alarms will cause a transmitter transfer in the case of a dual transmitter and a transmitter
shutdown in the case of a single.
Two other alarms that are indicated on the LCD, but not by LED, are
Observed Frequency - This alarm occurs when the built in frequency counter detects the
measured frequency is out of tolerance with the desired frequency.
Incorrect Identification - This alarm occurs when the monitoring circuitry detects a different
Identifier from the desired Identifier. The LED's above the monitor enable switch indicate the
present status of the transmitters. The PRI LED indicates the primary transmitter selected by the
main TX select key is the operating transmitter. The SEC LED indicates failure in the Primary
transmitter and the monitoring circuitry has commanded the transmitter to switch to the
secondary transmitter. The fail LED indicates that both transmitters have failed and the system
has shut down.
When testing the SE transmitter, Monitor Enable must be turned OFF.
4.3 Special Functions on the (SPCL FCTN) Key
All Functions are SPCL FCTN Key + Number
SPCL FCTN +1
This function stores all data into the onboard EEPROM. Once data is stored, the transmitter will
come back to the original settings if AC and DC power are lost.
SPCL FCTN +5
This function configures the Remote Control Unit.
SPCL FCTN +6
This function is a special test mode. In this mode the Master Controller will test for improper
identification. The Master Controller commands the Transmitter Control to add 32 to the ascii
value of every ID chararter. After the transmitter changes identification, it is still sending back
data on all of the parameters associated with that transmitter including identification. Once the
identification changes, the Master Controller will institute a transmitter changeover and shutdown
of the offending transmitter.
SPCL FCTN +7
This function is a special test mode. In this mode, the Master Controller will test for under power
shutdown. The Master Controller commands the Transmitter Controller to decrease the output
power by over 50%. As the transmitter changes power level, it is still sending back data on all of
the parameters associated with that transmitter. Once the power level drops below an
acceptable level, the Master Controller will institute a transmitter changeover and shutdown of
the offending transmitter.
SOUTHERN AVIONICS COMPANY
SE125 Installation and Setup4-6 Master Control Panel Description
SPCL FCTN +8
This function calibrates the modulation power, antenna current and frequency for each
transmitter. This offset compensates for the error that exists between the Transmitter Control
digital to analog converter and the measured output.
SPCL FCTN +9
This 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 a
given 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. First
the Master Controller commands the Transmitter Control to increase the RF output power in
increments of 5 Watts starting at 10 Watts and increasing to 125 Watts. It then reverses and
decreases by 5 Watts until the transmitter returns to 10 Watts output. It then will start increasing
the modulation level by 5% from 0 to 95%. The modulation then returns to 0% and the unit goes
back to power increase and decrease.

Logging Requirements:
•FRAM device, U27, on the Master Control board SLP43300
•Use of the Real Time Clock device on the Master Control board
•Latest firmware installed in both the Master Control and Embedded Ethernet Server.
In either a dual or a single SE Transmitter system, the SE Master Control panel firmware records
Date & Time stamp, Transmitter fault/shutdown and any Operator changes using U27’s 32K
bytes of FRAM on the Master Control board. The standard format follows:
nnn YYYY-MM-DD hh:mm:ss dddddddddddddddd
nnn = logged line number (3 characters)
YYYY = year (4 chars)
MM = month (2 chars)
DD = day of month (2 chars)
hh = hour (2 chars)
mm = minutes (2 chars)
ss = seconds (2 chars)
d… = data type. Either TX fault/shutdown or User changes (16 chars)
6.13.1 Local Logging
The user has the option to view, on the Master Control panel, logged data containing Faults,
Shutdowns and User Changes recorded for TX1 and TX2 for dual systems. When the LCD DATA
key is set for TX1’s data display, logged data represents only TX1’s activity. Alternately, when the
LCD DATA key is set for TX2’s data display, logged data represents TX2’s activity. A total of 300
lines of logged data for TX1 and another 300 lines logged for TX2 is available for the customer to
scroll through at any given time. Once the 300 line limit is reached the oldest entry will fall out of
the history. There are 40 bytes (characters) maximum on each line (row) on the LCD display as

At the heart of the SE series system is a class D Power Amplifier that operates through a low pass
filter, with RF sourced from a Direct Digital Synthesizer (DDS). The embedded microprocessor
lends itself nicely to automatic adjustment of system operating parameters. However, to ensure
proper operation, verification with calibrated test equipment is required.
7.1 Test Equipment Required
3 1/2 digit digital multi-meter (DMM), calibrated
dual trace oscilloscope, calibrated
frequency counter, calibrated (± 1 Hz accuracy)
250 Watt, 50 Ohm non-reactive dummy load
7.2 Dummy Load Hookup
Connect a 250 Watt, 50 Ohm, non-reactive dummy load to the RF output jack (J50), an N Type
RF connector, on the bottom of the enclosure.
7.3 Power Up

The SE125 has extensive BITE features that give the technician on site the ability to troubleshoot
the transmitter. Every stage in the transmitter has built in monitors to allow the technician to
troubleshoot down to an individual stage. As the signal is created and amplified, each step is
carefully monitored for correct operation. Each monitored function for each module in the SE is
described below.
Note: Certain parameters such as shutdown LED’s and overload LED’s are displayed as LED’s

From the above parameters, logical deductions can be obtained for identifying a defective
module during troubleshooting. The following information uses the number ID of each above
parameter.
Transmitter ON but NO output power:
This would be the most common problem that could occur. To look for a solution using BITE
parameters, start with the input and work to the output stage:
1. Is the LCD display operating? If yes, the 7.5V supply is OK. If not, check for a bad fuse or
power supply.
2. Check the following:
•Do the LCD up/down scroll buttons work? If yes, the Master Controller is most likely OK.
If no, replace the Master Controller PCB.
•Make sure none of the shutdown LED’s on the front panel, are illuminated. If so, reset the
transmitter.
3. Scroll down to the parameter MAIN DC Is its value approximately 48V If yes, move to next
step. If not, replace the Master Controller PCB since the Master Controller PCB gives the
command to turn on the Low Voltage (48V) Power Supply.
LVREG MODULE
4. Check the following parameters
•HV OUTPUT (170VDC +/- 15V)
•12VDC SUPPLY (12VDC +/-2V)
•5VDC SUPPLY (5VDC +/-. 5V)
If any of these parameters are missing, replace the LVREG/HVPS module.
SOUTHERN AVIONICS COMPANY
SE125 Installation and Setup8-4 Maintenance
PCMOD MODULE
5. Check the following parameters:
•If MODULATOR (I) or POWER CONTROL (I) LED’s are on, the PCM module has shut
down. Do a reset and test again.
•Check PWM DRIVE LVL. The value should be above 1.0V. If not, replace the
Transmitter Controller. If this is correct, move to next step.
•Check VMOD (OUT) for 50 Watts; this value should be approximately 100V +/- 15V. If
yes, move to next step. If no, replace the PCMOD module.
SPA MODULE
6. Check the following parameters:
•Check the SPA (I) FAULT LED. If this LED is illuminated, the SPA has shutdown due to
overload from a bad antenna, coaxial cable assembly, or antenna turning unit
malfunction. Find this problem first, then reset the transmitter and test again.
•RF PRESENT If this value is approximately 5V, then RF is present. If this is not ok,
replace the Transmitter Controller.
•5VDC SUPPLY (5.0V +/-.5V)
If these values are not correct, replace the SPA Module.
•VMOD (IN): This value should be close to the value of VMOD (OUT).
•SPA CURRENT: This value should be approximately 2A for 50W.
If these values are correct, the problem should be fixed. If not, the problem will be RELATED TO
THE antenna or ATU.

9.4 Antenna Theory
The range of a beacon and antenna depends on many variables and cannot be guaranteed. The
field strength can be calculated if the ground conductivity is known, but the field strength needed
depends on background environmental noise which depends on location. A field strength of
70uV/m is generally adequate in the United States and Europe but may not be sufficient in
latitudes between 30 degrees N and 30 degrees S.
9.4.1 Symmetrical “T” Antenna
A Symmetrical “T” Antenna is recommended for use with a 125 - 250 Watt transmitter if sufficient
land is available. This antenna requires a plot of ground approximately 150 feet by 400 feet for a
60 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 or
poles placed 300 feet apart and has a 55 foot vertical radiator and a 2 wire 280 foot horizontal top
hat. 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 ground
condition decreases with frequency. For a 70 uV/m field strength, the range over “good” ground
varies from approximately 60 miles at 190 KHz to 70 miles at 535 KHz with a 50 watt transmitter
and 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 2
wire 280 foot horizontal top hat. Range with this antenna over “good” ground varies from
approximately 90 miles at 190 KHz to 95 miles at 535 KHz with a 50 watt transmitter and from
approximately 105 miles at 190 KHz to 115 miles at 535 KHz with a 100 watt transmitter.
9.4.2 Tower Antenna
A Tower Antenna can be used if sufficient land is not available for a Symmetrical “T” Antenna. A
portion of the top set of guy wires is used to form the top hat for this antenna. A Tower Antenna
is electrically inferior to a Symmetrical “T” Antenna of the same height due to the decreased top
loading. Top loading serves two purposes; decreasing the input reactance and consequently the
voltage 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” ground
varies from approximately 40 miles at 190 KHz to 50 miles at 535 KHz with a 50 watt transmitter
and from approximately 60 miles at 190 KHz to 65 miles at 535 KHz with at 100 watt transmitter.

10 Antenna Tuning and Matching for PC1000C/3
The objective of this section is to setup the coupler to present a 50 Ohm, minimally reactive load
to the SE Transmitter. To ensure this, the inductance of the coupler should be adjusted so that
the measured PA current and voltage matches the values recorded in step 7.5.11 on page 7-3 as
closely as possible.
10.1
The SE Series transmitter is shipped with the default turn on power output set to Zero Watts. If
the power output has been changed, then connect the SE Transmitter’s RF output to a dummy
load.
Turn the system ON and verify that:
TX1 is set as Primary transmitter
The MODE is set to CARR
The OUTPUT POWER is set to Zero (0) watts into a DUMMY LOAD.
MONITOR is disabled
10.2
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 SE
Transmitter 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 switch
is ON.
10.5
Check the Reflected Power reading to determine the antenna’s state of tune. A value of 0, or
nearly 0, indicates the antenna is tuned. If it is tuned, go to step 10.10 on page 10-2 to ensure that
the best tap combination has been selected. If not, continue to step 10.6 on page 10-2.
SOUTHERN AVIONICS COMPANY
SE125 Installation and Setup10-2
10.6
Rotate the coupler’s INDUCTANCE from one limit to the other by using the CCW/CW switch
while in manual mode. Monitor the coupler meter tune reading during this process for a change in
reflected power. If a change is seen, place the switch in auto to allow the Autotune to make
adjustments 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 lower
setting and repeat step 10.4 on page 10-1 through step 10.6 on page 10-2. If the antenna does
not tune, change the FINE TAPS selector wire to the next higher setting and repeat step 10.4 on
page 10-1 through step 10.6 on page 10-2. Continue this bracketing procedure until the
Autotune 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 highest
setting. If the FINE TAPS selector is on the highest setting and it is necessary to increase the
inductance, change the Coarse Tap to the next higher tap and change the FINE TAPS selector to
the lowest setting. Due to overlap, it may be necessary to change the FINE TAPS selector a few
positions 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 Forward
Power level agrees with this setting. Adjust the Coupler’s front panel Sense control
counterclockwise 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 Switch
OFF.
10.10
Increase the coupler’s IMPEDANCE selector wire setting by one position, the, turn the Coupler
TX ON/OFF Switch ON. Set the RF Power Level to the transmitter’s maximum rated level, and
verify 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 in
step 10.9 on page 10-2. If the current level is greater than the recorded level, turn the Coupler
TX ON/OFF Switch OFF and decrease the IMPEDANCE selector wire setting by two positions
then turn the Coupler TX ON/OFF Switch ON. If the current level is less than the recorded level,
SOUTHERN AVIONICS COMPANY
SE125 Installation and Setup 10-3
turn the Coupler TX ON/OFF Switch OFF and increase the IMPEDANCE selector wire setting by
one position.
10.12
Repeat step 10.9 on page 10-2 through step 10.11 on page 10-2 until the IMPEDANCE selector
setting is found that gives the lowest Reflected Power level and results in a PA current and
voltage 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 the
transmitter’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 chattering
stops.
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 solder
the lead to the selected coarse tap on the coil.

12.1 Audio - SLP10020
12.1.1 General Description
The Audio PCB is an OPTIONAL addition to the standard system which allows the user to
broadcast AWOS announcements. The option is implemented as a daughter board to the Digital
I/O PCB and consists of four sections as follows:
•Audio Input Amplifier
•Automatic Gain Control (AGC)
•Chebyshev Passband Filter
•Voice Detector
The Voice amplifier takes the nominal -17 dBm signal level and amplifies it to a level usable by
the 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 -17
dBm and output a constant modulation level to the Digital I/O PWM section up to levels
exceeding +10 dBm. This section prevents inadvertent over modulation of the voice signal. It is
necessary since the Controller has no control over user input.
The Chebyshev Passband filter is designed for 300 to 3000Hz. The output at 4000Hz is down
more than 45 dB, ensuring any out of band audio signals from the operator will not cause
adjacent channel interference.
The Voice Detector has two functions. It detects the presence of an announcement sequence
and automatically attenuates the keying tone level down to 20% modulation. The announcement
level is summed with the keying tone level and set to achieve 95% composite modulation. This
action prevents over modulation and allows the announcement to be heard over the beacon
Morse code IDENT tones. The Voice Detector signals the Controller to temporarily suspend
modulation alarms, since the IDENT tone level is dropped below the alarm threshold.
12.1.2 Detailed Circuit Analysis
General Operation
The Audio PCB is an option that plugs into the Digital I/O PCB allowing an externally applied
signal, usually AWOS, to modulate the transmitter. The plug in provides amplification, automatic
gain control, audio pass-band filtering, and input detection and control.
SOUTHERN AVIONICS COMPANY
SE125 Installation and Setup12-2 Optional Equipment
Input Amplifier
The input differential amplifier takes a 600 Ohm or high impedance input depending on the
setting 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 drop
across R13 and R18. R8 and R22 couple this voltage to U2A and U3A. R15, R19, and
potentiometer R24 provide common mode rejection to be fine tuned for minimal line noise. JP2
is used when making this adjustment, and R16 and R25 set the gain of this stage. U2B, along
with the C7, R17 network, and R20, C10 network, provide a flat audio band response. The
output 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 potentiometer
R26 where it is coupled, via C16 and R30, to U1C. R28, R33, C18, and R29 provide midpoint
bias for U1C whose gain is set by R36, C21 and R38, C25. A sample of this signal is fed via C22
to 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 level
increases, the gate voltage on Q2 decreases and the resistance decreases, thus lowering the
audio input level to U1C pin 10 and holding the average audio output level constant. U1D boosts
the level of the audio signal, which is output through modulation level adjustment potentiometer
R31 and C19 as VOICE_FLTR_IN. A constant level output is also sent to
VOICE_DETECTOR_IN.
Pass-band Filter section
VOICE_FLTR_IN is coupled into a Chebyshev active pass band filter consisting of U4, U5, and
associated components. Its low end 3dB roll off point is 300Hz, and its high end 3dB roll off point
is 3000Hz, with sufficient attenuation to meet or exceed FCC requirements. The detailed theory
of operation of multi-stage active filters is beyond the scope of this manual and best left to a
textbook on the subject. The output of this stage is called VOICE_FLTR_OUT.
Voice Detector Section
The voice detector’s purpose is to notify the Controller that a voice announcement sequence is
beginning. This process automatically attenuates the normal IDENT output to allow clear
reception of the message and prevents over modulation. A sample of the AGC output is routed
as VOICE_DETECTOR_IN via C2 to buffer U1A. CR1 and C3, R4 convert the audio to a DC
level. When this level is enough to over come the bias on U1B pin 6, the output goes high
causing Q1 to virtually short one end of potentiometer R2 to ground. The adjustable leg of the
potentiometer leaves the board as VOICE_DETECT and connects to the TONE input line on the
Digital I/O PCB. Therefore, R2 becomes a shunt to ground, which is adjusted to lower the tone
level appropriately when an AWOS announcement is input. Buffer U3B provides an additional
level shifted output called VOICE_ON, which notifies the Controller external modulation is being
applied.

Note:
Read the User’s Manual & Installation Guide special emphasis is placed on review all safety
warnings prior to beginning this installation.
The 702M12-W Installation:
To install the Wireless Radio mounted to a DIN-Rail, bulkhead or an outdoor pole (see Pages 9 to
11 of the User’s Manual & Installation Guide on the CD provided).
Two options for DIN-Rail installation exist to mount the provided power supplies. Mount the rail
using either reference designator combination (1), (3), (5), (3), (4) and (2); or use the provided
sheet metal/wood screws reference designator (6), as seen in the Radio Link option drawing.
Mount the provided Power Supplies (7A2) and (7A4) to the Din-Rails. Ethernet Bridges (7A1)
and (7A3) should be mounted using sheet metal/wood screws (6). See Antenna mounting
instructions and use hardware provided with the antenna to mount. You will need a 10mm and
13mm socket to tighten antenna hardware.
Applying Power:
The M12A coded power connector is keyed, so a mating connection from the power supply can
only be made when the male and female ends are properly aligned. Connect one cable,
reference designator (5), between power supply (7A2) and Ethernet Bridge (7A1), and connect
one cable, reference designator (5), between power supply (7A4) and Ethernet Bridge (7A3). In
each case cut or tie back the green and white wires. These wires are available for redundant
supply use, see note below.
Notes: (Recommended 24V DC Power Supply provided)
•Only one power supply must be connected for full operation. For redundant power
operation V1 and V2 inputs must be connected to separate DC Voltage sources. The
transmitter will draw current from both sources simultaneously. Use 16-18 gauge wires
when connecting to the power supply.
Ethernet Connections:
Connect wire (6) between Ethernet Bridge (7A1) and the remote computer. Connect wire (2)
between Ethernet Bridge (7A3) and the SE Transmitter’s Ethernet Switch.

12.9 Internal 50 Ohm Dummy Load - SLF83350
The internal dummy load is not designed for continuous operation. Limit 125 Watt power
operation to fifteen (15) minutes.
This dummy load option provides an internal 50 Ohm non-inductive restive load to allow setup,
calibration and duration restricted burn in of the SE125 Transmitter. In order to use this option
the provided 7ft (2.1m) coaxial cable must be routed from the dummy load to the RF Filter output
of the desired transmitter drawer. With the transmitter drawer’s RF power off, the BNC Tee
connector is terminated to the RF Filter’s output. The remaining port of the BNC Tee connector is
intended to be routed to an Oscilloscope for Peak to Peak Voltage determination, Power
Calculation and signal quality measurements.
For infield installation: This option requires two holes to be drilled in the enclosure, so hardware
installation must be accomplished according to the provided documentation to ensure IP66
integrity.
