SECTION IV
THEORY OF OPERATION
4.1 GENERAL
The KY 96A, KY 97A Comm Transceiver is comprised of:
A. A single conversion VHF receiver utilizing a four pole varactor tuned prese-
lector, field effect transistors for the RF amplifier and mixer, an 8 pole monolithic crystal IF filter and integrated circuit IF amplifier.
B. A broadband transmitter with power transistors mounted on a die-cast alu-
minum heat sink followed by a three section elliptic function low pass filter.
C. A control section utilizing a microprocessor to:
1. Increment or decrement the selected frequency.
2. Store the “USE,” “STBY,” and 9 user programmable channels in non-volatile memory.
3. Remote transfer the “USE” and “STBY” frequencies and remote increment
the stored channels.
4. Light the display with a digital liquid crystal readout and control dimming of
the display.
5. Generate frequency code for the synthesizer.
D. A power supply made up of a discrete 9 volt regulator, 3 terminal 5 volt reg-
ulator.
E. A liquid crystal frequency display with variable backlighting and viewing an-
gle.
4.2 GENERAL CIRCUIT THEORY
4.2.1 Receiver
A receiver block diagram is shown in Figure 4-1. The received signal passes through
the low pass filter on the transmitter PC board and the T/R diode to the dual gate field
effect transistor RF amplifier. The desired signal proceeds to the dual gate FET mixer
Q103 where it is converted to 11.4 MHz, and fed through the monolithic crystal filter to
the integrated circuit IF amplifiers followed by the detector. Automatic gain control
voltage is fed back to the first and second IF amplifiers and the RF amplifier to achieve
more than 120 dB of dynamic range. The detected signal is not allowed to pass
through the squelch gate until the input signal has:
A. Exceeded the noise squelch setting or,
B. Exceeded the carrier level setting.
Rev 5, Apr 2003 MM 006-05674-0005.dwd Page 4-1
Page 10
B KY 96A, KY 97A
It proceeds through the low pass filter which attenuates all audio frequencies above
2.5 kHz. The audio signal is fed through the volume control to the integrated circuit
audio pre-amplifier. Its output will provide more than 100 milliwatts to a headphone,
or to an external audio mixer/amplifier.
An optional 4 ohm audio amplifier provides 4 watts on the 13.75 V units and 8 watts
on the 27.5 V units.
4.2.2 Transmitter/ Modulator
The transmitter block diagram is shown in Figure 4-2. In the transmit mode, the VCO
feeds a signal to the transmitter of the frequency selected in the “USE” display window
on the front panel. The signal is amplified by the broadband transmitter to the 5 watts
level and fed through the elliptic function 3 section low pass filter to the antenna.
Modulation is applied to the power amplifier by series modulating the 27.5 volt line
(13.75 for KY 97A) with mic audio. A small amount of mic audio is also fed to the receiver audio amplifier for sidetone.
4.2.3 Stabilized Master Oscillator
The stabilized master oscillator (SMO) I103 generates the RF drive for the transmitter
as well as the local oscillator for the receiver. The SMO synthesizes frequencies that
are referenced to a 25 kHz signal derived from a 3.975 MHz crystal oscillator. Receive
and transmit codes are fed to the synthesizer by the microprocessor (uP) and represent the frequency indicated in the “USE” window on the front panel.
4.2.4 Microprocessor and Display
Refer to microprocessor block diagram shown in Figure 4-3. The microprocessor (uP)
contains 4 k bytes of permanent Read Only Memory (ROM) for program instruction. A
32 byte non-volatile memory is used externally for frequency information storage. The
uP receives a 3.975 MHz clock signal from the synthesizer PLL IC which is derived
from a 3.975 MHz crystal.
The uP sends a serial 24 bit code to the synthesizer PLL IC (last 20 bits used) to determine the reference divide ratio. A serial 24 bit code (last 20 bits used) is also sent
to determine the divide ration of the “USE” frequency (when changed).
The increment/decrement switches send three pulses to the uP (up, pulse, down) in a
specific sequence to provide the code and validity check for increment and decrement
operations.
Display dimming controls are read through an analog to digital converter allowing the
aircraft lighting bus to dim the display.
The LCD display viewing angle is controlled by I801, which controls the display bias,
thereby controlling the display viewing angle based on inputs from R755, R802, and
Q803.

4.3 DETAILED THEORY OF OPERATION
Refer to schematics in Section VI of this manual.
4.3.1 Receiver
4.3.1.1 Antenna Input Circuit
In the receive mode Q101 is switched on, forward biasing the T/R diodes located on
the transmitter board. The desired signal passes through the first pole of the low pass
filter, then to the T/R diodes, and then to the receiver board. C102 steps up the impedance to match the first pole of the preselector.
4.3.1.2 Double Tuned Preselector
The first pole of the preselector is tuned by L101, C103 and CR101A. The signal is
coupled to the second pole of the preselector by L102. The second pole of the preselector is tuned by L103, C106 and CR101B. The matched varactor diodes, CR101A
and CR101B, are tuned to the desired frequency through a large resistor from the VCO
control voltage. The desired signal is coupled to gate 1of the RF amplifier by C107.
4.3.1.3 RF Amplifier Q102
Q102 and the associated parts make up the RF amplifier. The desired signal is applied to gate 1. The RF AGC is applied to gate 2. The RF amplifier has 20 dB of gain
at maximum RF AGC voltage, and 30 dB of attenuation with minimum RF AGC voltage; producing a dynamic range of 50 dB. C114 couples the desired signal to the double tuned interstage.
4.3.1.4 Double Tuned Interstage Network
The first pole of the interstage network is tuned by L105, C115 and CR101C. The signal is coupled to the second pole of the interstage network by L106. The second pole
of the preselector is tuned by L107, C118 and CR101D. The matched varactor diodes,
CR101C and CR101D, are tuned to the desired frequency through a large resistor
from the VCO control voltage. The desired signal is coupled to gate 1 of the mixer
through L133.
4.3.1.5 Mixer Q103
Q103 and the associated parts make up the mixer. The local oscillator signal is fed to
gate 2 at a frequency 11.4 MHz above the desired signal. The level of the local oscillator is between +4 dBm and +7 dBm. The desired signal is now at 11.4 MHz. The
drain of Q103 is tuned to 11.4 MHz by T101 and matched to the crystal filter.
4.3.1.6 Crystal Filter FL101
The crystal filter provides the desired selectivity. The input and output of the filter is
matched to 4100 ohms by T101 and T102 respectively.
4.3.1.7 First IF Amplifier I101
Rev 5, Apr 2003 MM 006-05674-0005.dwd Page 4-3
Page 12
B KY 96A, KY 97A
The desired signal is coupled from T102 to the first IF amplifier, I101. The first IF amplifier has about 45 dB of gain with 60 dB of dynamic range. IF AGC voltage is applied
to I101 on pin 5 through R124. R124 converts the AGC voltage to an AGC current.
The output is loaded with R245 for stability. T103 is tuned for 11.4 MHz and couples
the signal to the second IF amplifier.
4.3.1.8 Second IF Amplifier I102
The second IF amplifier has about 45 dB of gain with 60 dB of dynamic range. IF AGC
voltage is applied to I102 on pin 5 through R126. R126 converts the AGC voltage to
an AGC current. The output is loaded with R246 for stability. T104 is tuned for 11.4
MHz and couples the signal to the detector.
4.3.1.9 Detector
Transistor Q105 and capacitor C130 makes up the amplitude modulation detector. It
is biased near cutoff by transistor Q104, which the emitter-base junction provides bias
stability and temperature compensation. The demodulated signal is sent to the noise
amp, Q112, IF AGC, I105A, squelch gate, Q116, and to the demodulator buffer, Q131.
4.3.1.10 IF AGC Circuit
AGC voltage is derived from the average value of the detector collector voltage, which
is inversely proportional to the carrier level. The operational amplifier I105A filters out
the audio variations and integrates to the average voltage of the detector. R159 and
R160 set the maximum gain reduction at about 6.6 volts. As the detector collector voltage increases with a decrease in signal level, the AGC voltage decreases which increases the gain in the first and second IF amplifiers. The IF AGC voltage is made
available at TP105 and at the rear connector pin L. The AGC voltage at pin L is reduced by one diode drop (approx. 0.6 V).
4.3.1.11 RF AGC Circuit
The RF AGC voltage is applied to the RF amplifier from I105B. The RF AGC stays at
maximum voltage (maximum gain of amp) until the RF signal level reaches about 12.5
uV. The level at which it attacks is set by R184. When the IF AGC voltage exceeds
the reference voltage set by R184, the RF AGC voltage decreases, decreasing the
gain in the RF amplifier. RF AGC is made available at TP106.
The RF AGC is gated with TX(not) through CR120A such that when the unit transmits,
the RF AGC voltage goes to zero. This provides maximum attenuation in the RF amplifier during transmit.
4.3.1.12 Noise and Carrier Squelch Circuit
The carrier squelch circuit prevents the radio from squelching if an RF carrier greater
than 12.5 uV has been detected. I106B compares the RF AGC voltage, which is inversely proportional to the carrier level, to the reference level set by R183 and R185.
If the RF AGC voltage is greater than the reference level, then the unit is allowed to
squelch; if the noise level is large enough. When the RF AGC voltage is less than the
reference level, the output of I106B goes high; turning on Q140. When Q140 turns on,
Rev 5, Apr 2003 MM 006-05674-0005.dwd Page 4-4
Page 13
B KY 96A, KY 97A
the input signal to the noise amp is shorted to ground, causing the noise squelch circuit
to be inhibited.
Transistor Q112 amplifies the noise from the collector of the detector and limits its amplitude so that impulse spikes (such as ignition noise) will not be of a higher amplitude
than other noise. The output of Q112 is coupled to a 8 to 10 kHz bandpass filter,
I106A. The output of the bandpass filter is fed to the comparator, I107A. The signal
is compared to the reference level set by R176. When the noise signal is larger than
the reference level the comparator goes high charging C166. If C166 is charged greater than half the supply voltage, then the unit will be squelched.
CR107A and CR110B will squelch the radio in transmit.
4.3.1.13 Squelch Gate
Q116, Q117 and associated parts make up the squelch gate. The audio signal comes
from the detector at TP108; the detector biases Q116. When the unit is squelched the
base of Q117 goes to the supply voltage and its emitter follows. Since the emitters of
Q116 and Q117 are tied together, Q116 becomes reverse biased; attenuating the signal 70 dB.
4.3.1.14 Audio Low Pass Filter
Inductor L110 and its associated capacitors form a low pass elliptical filter. The filter
is at least 20 dB down at 4 kHz and the notch is at least 25 dB down at 4.5 kHz. The
filter does roll off below 350 Hz since the signal is AC coupled in and out of the filter.
The low frequency roll off reduces 60 cycle hum.
4.3.1.15 Audio Compressor
The received signal is coupled through C178 to the input of the compressor amplifier,
I111A. The output is fed to the volume control and to I111B. I111B will begin to discharge C179 when the amplitude to I111B exceeds the voltage across R210. Discharging C179 lowers the gate to source voltage on Q118, which reduces the drain to
source resistance on Q118. As Q118 is turned on, the amplitude at C178 is reduced.
This maintains a constant amplitude out of the compressor amplifier.
4.3.1.16 Audio Amplifier
The audio signal is routed through the volume control R902 to the audio amplifier,
I112A. The signal is amplified approximately 30 dB and capacitive coupled through
C187 to the auto-transformer, T107. The voltage and impedance are stepped up to
provide a minimum of 100 mW of audio power into 500 ohm load; such as headphones
or an audio panel. The sidetone, through R220, and the Mic intercom, through R218,
are also amplified by the audio amplifier.
An optional 4 ohm audio amplifier provides 4 watts on 13.75 V units and 8 watts on
27.5 V units. See audio board section for more details.
4.3.2 Stabilized Master Oscillator (SMO)
Rev 5, Apr 2003 MM 006-05674-0005.dwd Page 4-5
Page 14
B KY 96A, KY 97A
4.3.2.1 Synthesizer
The stabilized master oscillator is based around synthesizer I103 which is serial programmable by the microprocessor.
A 3.975 MHz crystal is attached to the gate oscillator, and the reference divider divides
it by 159 to produce the 25 kHz reference frequency. The RF frequency is divided by
the internal pre-scaler and divider then compared by the phase detector to the reference frequency. If the frequency is greater than 25 kHz the phase detector will pulse
up once every 40 usec. If the frequency is less than 25 kHz the phase detector will
pulse down. The greater the divided frequency from the reference frequency the wider
the phase detector pulse.
Q133, R137, and C135 integrates the lock detect pulses to send the lock detect signal
to the microprocessor. The reference oscillator is lightly coupled to Q132 which amplifies the 3.975 MHz signal for the microprocessor and I705 on the processor board.
The clock, data and strobe lines are driven from the microprocessor.
4.3.2.2 Voltage Translator
Q134, Q135, Q136, Q137 and their associated parts make up the voltage translator.
The voltage translator translates from five volt pulse to nine volt pulse and inverts the
logic of the pulses. The output of the phase detector is fed to the emitters of Q134 and
Q135. The bases of Q134 and Q135 are biased to about 2 volts so that when the
phase detector is tri-stated, Q134 and Q135 will be off. If the phase detector pulses
low, Q134 will turn on causing Q136 to turn on and a 9 volt pulse to appear at the output of the voltage translator, TP110. If the phase detector pulses high, Q135 will turn
on causing Q137 to turn on pulling the output to ground.
4.3.2.3 Low Pass Filter
The low pass filter is a lead/ lag network with a 2.5 kHz elliptical low pass filter with its
notch at 25 kHz. C235 and C236 make up the elliptical filter. R279, R280, R281, and
C237 make up the lead/ lag network. With this filter, the loop bandwidth is about 300
Hz and the 25 kHz notch is about 130 dB down. The control voltage is fed to the preselector through R136 and to the VCO through L132.
4.3.2.4 Voltage Controlled Oscillator (VCO)
Q108 and its associate parts form a modified Hartley oscillator. The varactor CR101E
is part of a matched set of five varactors so the preselector will track the VCO. C149
determines the range of the tuning voltage, the smaller the capacitor the larger the tuning range must be to maintain the same frequency range. C249 and R299 provide
bias stability. The tuning range is 118.00 MHz at 2.5 V and 151.375 MHz at 8.0 V.
4.3.2.5 VCO Buffer
Q109 and its associated parts form the VCO buffer. The VCO buffer provides isolation
from the transmit buffers and the mixer as well as amplifying the signal to about +7
dBm to the mixer.

4.3.2.6 Digital Buffer
Q106, Q107 and their associated parts form the digital buffers. The VCO is very lightly
coupled to the digital buffers through C147 so that noise from the pre-scaler will not
get back to the VCO. The signal is coupled to the pre-scaler through C140 at about
500 mV.
4.3.2.7 Transmit Buffers
The transmit buffers contain two stages of amplification. The RF signal is coupled
through C155 to Q110 and amplified. C157 couples the collector of Q110 to Q126.
Q126 amplifies the signal to approximately 24 dBm. The signal is coupled through
CR117 and C228 to create the transmit drive. The drive level is adjusted for different
transmitters by the resistor R1006. Q111 and Q139 are turned off during receive allowing Q110 and Q126 to be reversed biased. Q127 is also turned off during receive
preventing CR117 from being turned on. During receive the RF signal is reduced by
50 dB.
4.3.3 Modulator
4.3.3.1 Microphone Input Circuit
The microphone is connected to pin K of the rear panel connector. Mic bias is supplied
by R114 and R223. The signal passes through C191 to the Mic Gain control. Q119
is turned on during transmit to pass the signal to the modulator compressor.
4.3.3.2 Modulator Compressor
The audio signal is coupled through C230 to the input of the compressor amplifier,
I113A. The output is fed to the modulator amplifier, I113B will begin to discharge C198
when the output of the modulator exceeds the voltage across R267. Discharging
C198 lowers the gate to source voltage on Q120, which reduces the drain to source
resistance on Q120. As Q120 is turned on the amplitude at C230 is reduced. This
maintains a constant amplitude out of the compressor amplifier. R267 set the modulation level. The bias network R257 and R267 is run off of the mod bias voltage, so
that when the mod bias sags the modulation will decrease preventing distortion.
4.3.3.3 Modulator Amplifier
The output of the compressor amplifier is coupled to the modulator amplifier through
C194. The output is coupled to the modulator through C196 and T108.
4.3.3.4 Modulator Bias
The modulator bias (mod bias) regulates the supply voltage to just below half the supply voltage. Q123 is the regulating transistor and on the 28 volt versions Q122 is used
to buffer the regulating transistor. The KY 96A drops the modulator bias an additional
6.2 volts through CR123. R251, R254, and R256 set the regulated voltage, with R256
being adjustable. CR115 prevents overvoltage problems. RT101, R250, and R252
set the power reduction due to a thermal overload. When RT101 becomes hot, the
resistance goes up reducing the voltage at E113, causing CR114 to turn on, and thus
lowers the bias on Q123.

4.3.3.5 Modulator (14 Volts KY 97A)
The audio signal is applied to the primary of T108, which has a 4 to 1 turns ratio. This
steps up the voltage swing on the modulator transistors Q124 and Q125 enough to
make a 0 to 12 V swing to the transmitter final and driver. This output is also fed back
to the modulator compressor. The mod bias is fed to the secondary of T108 providing
the bias to Q125 with R247 being the current limit resistor.
4.3.3.6 Modulator (28 Volts KY 96A)
The audio signal is applied to the primary of T108, which has a 4 to 1 turns ratio. This
steps up the voltage swing to the bases of the modulator transistors Q124 and Q130
enough to make a 1 to 12 V swing on the transmitter final and driver. This output is
also fed back to the modulator compressor. The mod bias is fed to the secondary of
T108 providing the bias to Q124 and Q130 with R247 being the current limit resistor.
4.3.4 Transmitter
4.3.4.1 RF Amplifier
RF is fed from the transmit buffers to the RF amp, on the transmitter board, through a
miniature 50 ohm coaxial cable. The drive level is approximately 15 dBm. During receive the RF is attenuated as the TX(not) line goes high it turns on Q404 shorting the
drive to ground and removing the bias from pin diode CR403 to “OPEN” the input to
Q401. During transmit, the base current is supplied through R401 and CR403 to operate Q401 class A. Transformer T401 is broadband tuned and steps the collector impedance down to the input impedance of the driver.
4.3.4.2 Driver Q402
RF drive is fed through C412 and C437 to the driver, Q402. The driver is operated
class C and the collector is modulated through T402. The collector is broadband tuned
and is coupled to the final by T402.
4.3.4.3 Final
Capacitor C415, C416, and C440 form the input matching network for the final power
amplifier, Q403. The final is operated class C and is modulated at the collector. The
low collector output impedance is stepped up to approximately 50 ohms by transformer T403.
4.3.4.4 Low Pass Filter
A three section elliptical low pass filter is placed between the final and the antenna to
attenuate all harmonics which may be generated in the transmitter. During transmit
the T/R diodes CR401 and CR402 are reversed biased to protect the receiver from 5
watts of power.
4.3.5 Microprocessor
4.3.5.1 Communication to Synthesizer PLL I702
Rev 5, Apr 2003 MM 006-05674-0005.dwd Page 4-8
Page 17
B KY 96A, KY 97A
The microprocessor (uP), pin 32, sends two 24 bit serial data streams to the synthesizer PLL IC (I103) on the main board. Only the last 20 bits are used by the synthesizer PLL IC. The first stream provides the crystal divide ration and the second provides the frequency to be divided. Each data bit is clocked from pin 33 of the uP. At
the end of each data stream, a high going strobe pulse is sent from pin 28 of the uP to
latch the last 20 bits of data into the synthesizer PLL IC.
When the synthesizer is locked, pin 25 (Lock Detect) of uP is pulled high from the synthesizer PLL IC I103. If pin 29 (Mic key(not)) of uP is low, pin 22 (TX) of the uP is taken
high to turn on the transmitter when synthesizer is in lock. The gate of Q701 must be
pulled low for the uP to take TX high. Then TX is inverted through Q707 to turn on the
transmitter.
4.3.5.2 Communication to Non-Volatile Memory
When the non-volatile memory (I704) is being addressed, pin 24 of the uP is high.
When reading from the memory, a 16 bit serial code/ address stream is sent out on pin
32 of the uP, then a serial 16 bit data stream associated with the address is read back
on pin 31 of the uP. When writing to the memory, a 16 bit serial code/ address stream
followed by a 16 bit serial data stream associated with the address, are sent out of pin
32 of the uP. Only the last 9 bits of the 16 bit code/ address stream are used by the
non-volatile memory. Each bit of the code/ address and data streams is clocked from
pin 33 of the uP.
4.3.5.3 Communication to Analog to Digital Converter
When the analog to digital converter (A/D) (I706) is addressed, pin 23 of the uP is low.
A serial 8 bit address stream is sent to the A/D from pin 32 of the uP requesting conversion data. Simutaneously, a serial 8 bit data stream of the last requested conversion data is received from the A/D on pin 31 of the uP. This makes communication
full duplex. Only the first 4 bits of the address stream are used by the A/D. Each bit
of the address and conversion data streams is clocked from pin 33 of the uP.
The A/D uses a system clock for its conversion time. The 496.875 kHz system clock
is generated from I705, a binary counter. The 3.975 MHz clock signal (synthesizer
PLL IC) on pin 1 of I705 is divided by 8, then output on pin 9 of I705.
4.3.5.4 Microprocessor Reset Circuit
During normal operation the output on pin 13 of I701A is 5 volts DC. The 5 volts DC
on pin 40 (Vdd) of the uP, is produced through the 5 volt regulator I108 on the main
board. On power up, the 9 volts on the input of I108 must reach 7.3 volts DC before
5 volts DC is produced on the output of I108. Therefore, on power up the uP (pin 1) is
held in reset until the 9 volt DC reaches 7.9 volts DC. Pin 11 of I701A must reach 6.2
volts DC to accomplish this. On power down, the 9 volt DC must drop to 7.5 volts DC
before the uP is put into reset.
4.3.5.5 Display
Rev 5, Apr 2003 MM 006-05674-0005.dwd Page 4-9
Page 18
B KY 96A, KY 97A
The display is a liquid crystal (LCD) type with three sections (“USE,” “STBY,” and
“CHAN”). The “USE” frequency, which is the active frequency, is displayed in the
“USE” window at all times. A standby frequency, which can be exchanged with the
“USE” frequency, is displayed in the “STBY” window when in standby entry mode.
When in channel or program mode, the channel frequency is displayed in the “STBY”
window and the channel number is displayed in the “CHAN” window. When in channel
mode the letters “CH” are displayed between the “CHAN” and “STBY” windows. When
in program mode the letters “PG” are displayed to the left of the “STBY” window. The
letters “TX” are displayed to the right of the “USE” window during transmit.
The uP I702 sends a 112 bit serial stream through pin 10 to pin 1 of I801 (LCD driver)
on the display board. The serial stream contains backplane/ mode and segment information. Each bit is clocked through pin 11 of the uP I702.
The LCD display viewing angle is controlled by the bias provided by I801 to the display. The output of the voltage divider formed by R755, R801, and R802 is applied to
the base of Q803. The collector of Q803 is connected to +5 Vdc, and the emitter is
connected to I801 pin 12 which provides I801 with a reference voltage, which sets the
bias level applied to the display by I801.
The display brightness is controlled in three different ways, dimming through the aircraft 14 or 28 Vdc lighting bus or half brightness all the time.
When the aircraft 14 Vdc lighting dimmer bus is selected, pins 7 and 9 of I702 are low
and pin 8 of I702 is high. This turns on Q704 thereby pulling E705 low which supplies
a ground to 3 of the 6 light bulbs for the LCD display backlighting. Q705 is off allowing
the 14 Vdc lighting voltage to pass through CR703 to E704 to supply +14 Vdc across
two sets of 3 light bulbs in series for the LCD display backlighting.
When the aircraft 14 Vdc Max lighting option is selected, pin 9 of I702 is low and pins
7 and 8 of I702 are high. This causes Q704 and Q705 to be on, placing E704 at
ground and E704 at +14 Vdc.
When the aircraft 28 Vdc lighting dimmer bus is selected, pin 7, 8, and 9 of I702 are
low. This causes Q709 to be on, placing E705 at +28 Vdc.
When the aircraft 28 Vdc Max lighting is selected, pins 7 and 8 of I702 are low and pin
9 of I702 is high. This causes Q702 to be on and Q709 to be on thereby pulling line
E705 to +28 Vdc.
4.3.6 Audio Amplifier Board
The audio amplifier board consists of a summing amplifier and a 4 watt/ 8 watt amplifier.
I1201A and associated parts form the summing amplifier. Three 500 ohm auxiliary inputs are loaded by R1201, R1202, and R1203. The summing amplifier reduces the
Rev 5, Apr 2003 MM 006-05674-0005.dwd Page 4-10
Page 19
B KY 96A, KY 97A
auxiliary inputs to the desired level to be fed to the Mic Intercom input. C1207 filters
high frequency noise and C1210 filters low frequency noise. The output of the summing amplifier is routed through the main board Mic Intercom input and back through
the main board Comm Audio Out.
Comm Audio In goes through R1214 and is reduced by an inverting amplifier, I1201B,
to prevent distortion through the FET switch, Q1202. The gate of Q1202 is pulled up
by R1219 allowing Q1202 to pass the audio signal. When the TX line is grounded
Q1202 turns off reducing the signal by al least 40 dB.
Q1203, Q1204, Q1205, Q1206, Q1207, and Q1208 form a trans-resistive amplifier
with 18 dB of gain. The feedback resistor, R1237, provides 23 dB of desensitization
to gain changes due to temperature or part variations. CR1202 and CR1203 reduce
crossover distortion. C1219, C1220, C1227, and C1221 reduce the gain above the
audio passband to prevent oscillation. The audio drivers, Q1207 and Q1208, provide
a minimum of 4 watts for 13.75 V units and 8 watts for 27.5 V units into a 4 ohm load.
The output is fused by F1201 to protect the drivers. R1238 is in parallel with the fuse
to provide residual audio in case the fuse blows.

vice sets. The 122-XXXXX-XXXX P/N series designates discrete programmed devices within
the 126- P/N and 125- P/N device sets.
The top unit parts list contains the 206- P/N unit software/hardware configuration set. In some
cases, specific versions of 206- P/N unit SW/HW configuration sets must be used in specific
versions of unit part numbers. An example of a 206- P/N unit SW/HW configuration set is
shown in figure 6-0, sheet 1, item “A” in the right hand margin.
The last two or four digits of software related P/N's indicate the revision number (-XXRN) of
the software. Those numbers are incremented with each revision of software.
If a circuit board contains software, the applicable 205- P/N is used to order the programmed
software/hardware board set. A board with software cannot be ordered by hardware 200- or
300- P/Ns. The applicable 122- P/N is used to order programmed devices. In some cases,
specific versions of programmed devices must be used with specific versions of other programmed devices in the unit. Programmed devices cannot be ordered by 125- or 126- P/Ns.
6.3.1 UNIT SOFTWARE/HARDWARE SYSTEM SET
The 206- P/N is the configuration control for all unit software, software/hardware circuit boards,
and programmed devices in the unit. The 206- P/N parts list contains the software identification tag and any 205- P/N software/hardware board sets. The last two or last four digits of the
206- P/N designate the software/hardware configuration version of the unit, depending on
whether the unit part number is 9-digit or 12-digit.
6.3.1.1 When the unit part number is 9-digits on the TSO label, the last 2 digits of the 206- P/N
are the last two digits of the software identification tag attached to the unit. The SW identification tag part number is 057-03284-00XX, where XX is the last two digits of the 206- P/N.
6.3.1.2 When the unit part number is 12-digits on the TSO label, the last 4 digits of the 206- P/
N are the last 4 digits of the software identification tag attached to the unit. The SW identification tag part number is 057-05287-YYYY, where YYYY is the last four digits of the 206- P/
N. The two types of software identification tags are illustrated below.
6.3.1.3 The 205- P/N software/hardware board sets used in the unit appear on the 206- P/N soft-
ware/hardware configuration set parts list. An example of a 205- P/N software/hardware board
set is shown in figure 6-0, sheet 1, item “B” in the right hand margin.
6.3.2 SOFTWARE/HARDWARE BOARD SETS
The 205- P/N series designates software/hardware board set assemblies. The 205- P/N parts
list contains 057- P/N SW/HW board labels, and contains 125- P/N software programmable
device sets and/or 126- P/N non-software programmable device sets that fulfill software requirements. The 125- P/N and 126- P/N device sets contain 122- P/N programmed devices.
The 205- P/N parts list also contains the 200- P/N or 300- P/N hardware circuit board.
6.3.2.1 The 057- P/N SW/HW board labels:

6.3.2.1.1 For 9-digit 205-WWWW-RN board labels, the first 7 digits are contained on a label part
number 057-050WW-00WW, and the last two digits are specified by 057-05252-00RN. The
revision number (RN) of the 205-WWWW-RN and the 057-05252-00RN part numbers are incremented when the revision number of any 125-0XXXX-XXRN part number is incremented.
Therefore, the revision number of the 205-WWWW-RN and 057-05252-00RN part numbers
will be the same.
6.3.2.1.2 For 12-digit 205-0XXXX-XXRN board labels, the first 10 digits are contained on a label
part number 057-05252-XXXX, and the last two digits are specified by 057-05335-00RN. The
revision number (RN) of the 205-0XXXX-XXRN and the 057-05335-00RN part numbers are
incremented when the revision number of any 125-0XXXX-XXRN part number is incremented.
Therefore, the revision number of the 205-0XXXX-XXRN and 057-05335-00RN part numbers
will be the same. A circuit board identification tag is illustrated below.
205-06616-
6.3.2.2 The 125- software programmable device sets:
The 205- P/N SW/HW board set may contain one or more 125- P/N software programmable
device sets. A 125- P/N software programmable device set contains software and one or more
122- P/N programmed devices designated for that software function. When the revision number (RN) of any one of the 122-0XXXX-XXRN programmed devices is incremented in a new
software release, the revision number the 125-0XXXX-XXRN device set is also incremented.
This 125- P/N parts list also specifies the “U” or “I” circuit designators for the programmed devices found on assembly drawings and schematic diagrams. Examples of 125- P/N sets are
shown in figure 6-0, sheet 1, items “C1,” and “C2” in the right hand margin.
6.3.2.3 The 126- P/N non-software programmable device sets:
When specified at the 205- P/N SW/HW board set level, the 126- P/N non-software programmable device set fulfills software requirements. The 126- P/N parts list contains one or more
122-0YYYY-YYRN P/N programmed devices. An example of a 126- P/N set that fulfills software requirements is shown in figure 6-0, sheet 1, item “C3” in the right hand margin.
6.3.2.4 The 122- P/N programmed devices:
The 122-0XXXX-XXRN part number identifies discrete programmed devices found in both
software programmable 125- P/N device sets and non-software programmable 126- P/N device sets that perform a software function. These parts also appear on the 200- P/N or 300P/N hardware board parts list as 122-0XXXX-9999. Their true part number is found only on
the 125- P/N or 126- P/N parts list.

6.3.2.5 The 200- P/N or 300-P/N hardware board:
The 200- P/N or 300- P/N hardware circuit board is specified by the 205- SW/HW board set.
An example of a 200- P/N hardware board reference on a 205- SW/HW board set is shown in
figure 6-0, sheet 1, last line.
6.3.3 HARDWARE BOARDS WITH PROGRAMMED DEVICES
The 200- P/N or 300- P/N hardware board parts list contains 126- P/N non-software programmable device sets that fulfill hardware requirements and reference to all 122- P/N programmed
devices on the hardware board.
6.3.3.1 The 126- P/N non-software programmable device sets:
Rev 5, Apr 2003 MM 006-05674-0005.dwd Page 6-11
Page 50
B KY 96A, KY 97A
The 126- P/N non-software programmable device sets that fulfill hardware requirements appear on the 200- P/N or 300- P/N parts list.
6.3.3.2 The 122- P/N programmed devices:
The 122- P/N programmed devices appear on the 200- P/N or 300- P/N parts list. These references resolve device location on the board. Component designators are placed in the SYMBOL field of the parts list to specify component location. These include 122-3XXXX-9999 or
122-0YYYY-9999 part numbers.
The 122- numbers in the form 122-3XXXX-9999 are used for non-software programmable devices (126- P/N) that fulfill hardware requirements. Examples of such 122- P/Ns are shown in
figure 6-0, sheet 2, items “D5” through “D10” in the right hand margin.
The 122- numbers of the form 122-0YYYY-9999 are used for both software programmable devices (125-) (Items D12 through D15, in the example), and non-software programmable devices (126-) (Item D11, in the example), that fulfill software requirements.
These programmable device sets appear on the hardware/software board (205-) parts list.
The exact programmable device (the resolution of the -9999, in the above items) is specified
by the respective software programmable device set (125-), or the non-software programmable device set (126-) parts list.
Using the SYMBOL field as specified above, would discourage the use of the SYMBOL field
for this purpose, in the programmable device sets (125- and 126-) parts list. This would then
permit the specification of the same programmable device sets in different boards, hence different component designators. In the example, Figure 6-0:
• The items flagged D1 through D4, in the right margin, are non-software programmable
device sets.
• The items flagged D5 through D10, in the right margin, are non-software programmable device designators, that fulfill hardware requirements.
• The item flagged D11, in the right margin, is a non-software programmable device designator, that fulfills software requirements.
• The items flagged D12 through D15, in the right margin, are software programmable
device designators, that fulfill software requirements.
Figure 6-0, while closely related to a specific product, does not represent an exact configuration in use by that product. The example has been modified to clarify certain points.
