AN/URC-119(V) HF COMMUNICATIONS SYSTEM
(Ground Radio Communications Journeyman/Craftsman)
SECTION A: GENERAL
1. This Air Force Job Qualification Standard (AFJQS) and attached Air Force Qualification Training
Package (AFQTP) standardize on-the-job training (OJT) tasks and constitute an approved training program
for the AN/URC-119(V). The AFJQS and AFQTP are used by unit training managers, supervisors, trainers,
trainees, and other training functions to plan, conduct, and document OJT on this equipment.
2. Maintain the AFJQS IAW AFI 36-2201, AFI 36-2233, and AFMAN 36-2247. Routine changes will
be accomplished via page changes and urgent changes will be disseminated via message. Enter additional
local tasks in the blank areas on the AFJQS or add forms. Develop Task Training Guides for added tasks;
they should be consistent in content and format with those in the AFQTP. Submit recommended
AFJQS/AFQTP improvements/corrections to the 81 TRSS Qualification Training Flight (81 TRSS/TSQS),
601 D Street, Keesler AFB MS 39534-2229.
3. Review Air Force publishing bulletins and AFIND8 to identify available training materials. Use this
AFJQS in conjunction with other applicable JQSs or the Career Field Education and Training Plan (CFETP)
and locally assigned tasks to identify work center duty positions. Also, use this AFJQS along with other
applicable JQSs and the CFETP to evaluate newly assigned personnel and identify individual training
requirements.
4. Tasks listed on the AFJQS have been selected IAW the Instructional System Development (ISD)
process and are the minimum, mandatory AF training requirements for this equipment/function. The “X”
code in the Core Task column of the AF Form 797 is used to indicate that the individual must be trained and
certified on that particular task. The “X*” code identifies tasks that may not be common to all equipment
configurations; however, the task must be trained if it is assigned to the individual’s duty position. The “—”
code is used to indicate that training on this task is a local determination while ensuring 100% task coverage
within the work center.
5. Trainees must accurately perform each assigned task unassisted IAW Technical References (TR) prior
to being certified. To qualify for skill-level upgrade, trainees must be certified on assigned tasks,
satisfactorily complete career knowledge training, and meet mandatory specialty qualifications IAW AFI 36-
2101, AFI 36-2201, and AFMAN 36-2108. After upgrade, assign individuals to other work center duty
positions and continue qualification training.

SECTION B: DOCUMENTATION
1. AFJQS/CFETP tasks will be compiled in an automated training management system, such as the Core
Automated Maintenance System (CAMS), if available. The system must contain each AFJQS/CFETP title
line with appropriate AFJQS/CFETP numbers, titles, and dates. AFJQS/CFETP and automated
documentation requirements are listed below. The alphanumeric AFJQS number is converted to a dotted
decimal number for use in CAMS. Alphanumeric numbers have been converted by retaining the 200 series
number and changing the alpha character to the corresponding number, i.e., -200B becomes -200.2 and -
201LB becomes -201.12.2.
a. Load applicable tasks in the automated training system or identify training requirements by
circling the task numbers on each individual's AFJQS/CFETP.
b. If task statements contain more than one noun or action verb which precludes certification on the
entire task, load/circle the noun or verb to indicate the individual is being trained only on that portion of the
task.
c. When training is started on a task, enter the start date in the appropriate place. When training is
complete, document training and task certification IAW local certification procedures.
2. The identification blocks listed below are to be used when the trainer is other than the trainee's
immediate supervisor.

ABOUT THIS TRAINING PACKAGE
This AFQTP was originally developed by SSgt Carl Alexander.
It was revised by TSgt William S. Mabb, 81 TRSS
Qualification Training Flight. MSgt William E. Bowman was
the Training and Education Specialist. SSgt John C. Pauls of
the 30 CS, Vandenberg AFB, CA, also supported the
development as AN/URC-119(V) subject matter expert. It was
field tested and validated at the 1 CCGP, Lindsey AS, GM.
For more information on the 81 TRSS Qualification Training
Flight and a list of other products that are available, feel free to
visit our home page at http://www.keesler.af.mil/81trss/qflight.
IMPORTANT INFORMATION
The following training guidance is intended for use by qualified
trainers. It is mandatory that trainers complete Air Force
Training Course J6AJI3S251-000 before attempting to train
anyone on this material. Contact your unit training manager to
obtain training on this course.
This training package was developed with four objectives in
mind.
• Standardize on-the-job training.
• Reduce training time while maintaining proficiency
standards.
• Provide trainers and trainees with a logically organized
training plan which yields immediate and measurable
feedback.
• Provide a standard to measure task knowledge and
performance during personnel evaluations.
HOW TO USE THIS TRAINING PACKAGE
PACKAGE DESCRIPTION
This training package consists of
• an AF Form 797 that lists all tasks performed during
development of OJT material that require structured training
and certification.
• a Trainer’s Guide that provides the trainer with instructions
on how to effectively conduct on-the-job training using this
training package. The Trainer’s Guide includes Task
Training Guides (TTG) and covers every task listed on the
AF Form 797. The task evaluation checklists reflect the
major areas of a task which must be performed satisfactorily
TG 2E1X3-206N, Page iii
before certification. A Training Completion Certification is
attached.
• Skill Training Material (STM) which contains training
modules, review questions, performance procedures, and a
review question confirmation key.
• a Knowledge Evaluation Pamphlet (KEP) which contains a
test for each module. Keep the pamphlet separate until you
are ready to administer the tests. Detach and store the KEP
Key and Answer Sheet(s) in a secure place to ensure the
KEP is not compromised.
INSTRUCTIONS FOR USING THIS TRAINING PACKAGE
• Review the trainee’s training record (AF Form 623) and
determine the trainee’s previous training and certification.
• Assign the trainee to a duty position and develop the
trainee’s individual training plan (ITP) (see Figure 1 for an
example of a computer-generated plan). Using the ITP,
select the first task for training and review the applicable
TTG.
• Ensure all training references are available and all
prerequisites for that task are met.
• Discuss with trainee the task objective(s) and training steps.
Assign corresponding STM module for the trainee to
complete.
• When you are satisfied with the trainee’s knowledge of the
material, administer the KEP. (Normally, the trainee is
NOT permitted to use TRs but if TR use is permitted, it will
be stated at the beginning of each KEP test and a score of
100% required. Otherwise, the trainee must score a
minimum of 70% on the KEP tests.) Check the trainee’s
answers against the KEP Confirmation Key and review
missed questions with trainee to ensure understanding of the
material. If the score is less than what is required, have the
trainee restudy the module and retake the test. Using TRs
and the Task Evaluation Checklist as guidance, explain the
task performance procedures to the trainee. Demonstrate
the task procedures to the trainee and answer any questions.
Have the trainee practice and explain the task procedures to
you.
• Have the trainee perform the task procedures unassisted.
Using the Task Evaluation Checklist, evaluate the trainee’s
performance. Should the trainee fail, determine the cause of
unsatisfactory performance. Reevaluate the trainee when
you are satisfied the task can be performed unassisted.
When the trainee performs the task at the desired level of
Page iv, TG 2E1X3-206N
proficiency without assistance, document training and task
certification IAW local certification procedures.
• Using the ITP, assign additional tasks until the trainee
completes the requirements for the duty position. If, before
completing this training package, the trainee is reassigned to
another location which has a need for this training, we
recommend you forward the training material to the gaining
work center.
• Schedule periodic evaluations after the trainee is task
certified. You may use the performance procedures, task
evaluation checklists, or the KEP.
• When training is completed, remove the attached Training
Completion Certification and give it to the trainee so he/she
may make recommendations, suggestions, or offer
corrections to the training package in the comments section.
Mail the completed Training Completion Certification to the
address specified. Upon receipt of a properly completed
training certification, a Certificate of Training will be
forwarded through channels to the trainee.

SYSTEM CHARACTERISTICS
The URC-119(V) provides long-range HF voice and data
communications for fixed plant, transportable, shelter, and
mobile stations. The exceptionally rugged industrial/military
design and construction of the URC-119(V) system guarantees
reliable operation under demanding field conditions.
The URC-119(V) is tuned by simply selecting a frequency (or
preset channel) and keying the transceiver. All other tuning
functions, including Linear Power Amplifier (LPA) and antenna
tuning, are performed automatically.
Power for the system can be 115VAC, 230VAC, 12VDC, or
28VDC selectable. The remote controls do not require internal
strapping for the various power requirements.
Page 1-2, STM 2E1X3-206N
Figure 1-1. 100W Configuration
STM 2E1X3-206N, Page 1-3
The frequency range of the URC-119(V) is from 1.6000MHz to
29.9999MHz. The modes of operation are USB, LSB,
Amplitude Modulation Equivalent (AME), Continuous Wave
(CW), and Audio Frequency Shift Keying (AFSK), with option
installed. There are several ancillary pieces of equipment that
can used to provide various system configurations. The system
can be configured for 100W by using the transceiver only, or
for 500 or 1000W when used with a LPA.

SYSTEM CONFIGURATIONS
As shown in Figure 1-1 in this module, the RT-1446
Transceiver, along with the CU-2310 Antenna Coupler, make
up the 100W system.
100W SYSTEM
The RT-1446 is a microprocessor-controlled transceiver,
conservatively rated at 100W Peak Envelope Power (PEP) and
Average (AVG). The solid-state power amplifier ensures
continuous rated output power during keydown operation. All
operating and metering functions of the transceiver are fully
remote controllable over 2/4-wire telephone lines.
Additionally, the built-in telephone patch and internally
mounted AFSK option provide full communication flexibility.
For a simplified functional diagram of the transceiver, refer to
Figure 1-2 in TO 31R2-2URC-81.
Page 1-4, STM 2E1X3-206N
TRANSMIT PATH
In the transmit mode, the 100W transceiver accepts
audio/keyline inputs from a CW key, handset/mic, telephone
line, or other source, and impresses the audio on a 455kHz
intermediate frequency (IF) carrier. The 455kHz IF is raised in
two conversions to the 1.6 to 30MHz transmitting range and
amplified to a signal level of 100W PEP or AVG into a 50-ohm
load.
A directional bridge in the transmit path measures the forward
and reflected power levels. This information is used for front
panel display and for transmitter gain control functions. A
transmit/receive (T/R) switch separates the transmit and receive
paths, which allows connection to a common antenna.
RECEIVE PATH
In the receive mode, the 1.6 to 30MHz received signals bypass
the power amplifier and are reduced to a 455kHz IF using a
double conversion process. The first conversion is made at an
IF of 40.455MHz and band pass filtered to remove undesired
image frequencies. The second conversion is made at an IF of
455kHz and band pass filtered to achieve selectivity. The
resulting 455kHz IF signal is demodulated with an amplitude
detector (Amplitude Modulation (AM) Mode) or product
detector (Single Sideband (SSB) Modes) to obtain the audio
output.
Control of the 100W transceiver is from the front panel or by
remote input. Logic signals are processed by a microprocessor
that provides the necessary memory, control, logic, and timing
to coordinate the functions of the 100W transceiver in all modes
of operation. The microprocessor also controls the detection
and display indications of the Built-In Test (BIT) circuits.
The synthesizer and reference/Beat Frequency Oscillator (BFO)
modules generate the frequencies used in the modulation,
demodulation, and double conversion processes. All reference
frequencies are derived from a stable 10MHz frequency
standard.
The CU-2310 Antenna Coupler automatically matches the
output impedance of the transceiver or 500W LPA to a whip or
long wire antenna over the frequency range of 1.6 to 30MHz.
Operation, including network tuning, is fully automatic. Tuning
time is typically 5 to 8 seconds. The antenna coupler is used
where the required characteristic load impedance is other than
50 ohms.
STM 2E1X3-206N, Page 1-5
Typically, antennas do not exhibit constant 50-ohm impedance
over the 1.6MHz to 30MHz range. The antenna coupler
matches the antenna to the transceiver or 500W LPA so that at
the operating frequency, a 50-ohm load is presented to the
transmitter. Refer to Figure 1-2 in TO 31R2-2URC-111 for a
simplified functional diagram.
RF from the transceiver enters the coupler and is sampled by a
discriminator sampling circuit. An impedance matching
transformer (A1T2) matches the coupler operating impedance
of 12.5 ohms to the standard 50-ohm transmission line. Main
tuning capacitor (A2C1) and main tuning inductor (A2L1) are
placed in the circuit when needed to tune a long wire antenna.
500W SYSTEM
Figure 1-2 in this module shows the equipment that makes up
the 500W system. The only difference between this
configuration and the 100W configuration is the addition of the
AM-7223 RF amplifier. Power for this configuration is
supplied from either an AC or DC source. The output level
delivered by the amplifier is 500W PEP with multiple tone
input signals or 250W AVG with lock keyed CW or a
continuous single tone input signal.
This LPA is designed for continuous operation under severe
environmental conditions in either fixed or mobile applications.
Automatic sensing circuits protect the LPA from damage due to
overdrive, abnormal tuning, high Voltage Standing Wave Ratio
(VSWR) (including open or short circuit conditions), high and
low line voltages, insufficient air flow, and over temperature.
Figure 1-2 in TO 31R2-2URC-101 shows a simplified block
diagram of the AM-7223 RF amplifier. Refer to this figure as
we cover the signal flow of the amplifier.
TRANSMIT PATH
In the transmit mode, the transceiver RF signal is routed by the
T/R relay on the output filter assembly to tube assembly (A1),
where it is amplified. The RF signal then passes through the
tuned 500W tank assembly (A2) to the low pass filter and the
VSWR bridge circuit on the output filter assembly. From the
VSWR bridge circuit, the RF signal is applied to the antenna
connector J5 on the 500W LPA via the T/R relay.
Page 1-6, STM 2E1X3-206N
RECEIVE PATH
In the receive mode, the RF signal from the antenna connector
is routed to the XCVR RF connector via the T/R relay on the
output filter assembly.
1000W SYSTEM
Figure 1-3 in this module shows the equipment that makes up
the 1000W system. The difference between this configuration
and the 500W configuration is: the AM-7223 RF amplifier and
CU-2310 Antenna Coupler are replaced with the AM-7224 RF
amplifier, associated power supply (PP-7913/URC), and the
URA-38 antenna coupler. It is important to remember that an
antenna coupler can be omitted with this RF amplifier in this
particular configuration.
The AM-7224 RF amplifier is a 1000W amplifier used when
100 or 500W applications are not acceptable. Power for the RF
amplifier is provided by the PP-7913 power supply. Refer to
Figure 1-2 in TO 31R2-2URC-121 for a simplified block
diagram of the AM-7224 RF amplifier.
TRANSMIT PATH
In the transmit mode, the XCVR RF signal is routed by the T/R
relay on the VSWR/XFMR assembly to the tube assembly (A1),
where it is amplified. The RF signal then passes through the
tuned 1kW tank assembly to the impedance select circuit on the
VSWR/XFMR assembly. The RF signal is applied through a
VSWR bridge circuit on the VSWR/XFMR assembly to the low
pass filter assembly on the antenna connector of the 1kW LPA.

STM 2E1X3-206N, Page 1-9
RECEIVE PATH
In the receive mode, the RF signal from the antenna connector
of the LPA is routed through the low pass filter assembly to the
XCVR RF connector via the T/R relay on the VSWR/XFMR
assembly.
The PP-7913 power supply produces three output voltages:
+3000VDC at 1A, +13.5VDC at 8A, and 115VAC at 1 amp(A).
These voltages are supplied to the AM-7224 RF amplifier.
The AN/URA-38( ) Coupler and Coupler Control are capable of
handling the output power of the AM-7224 RF amplifier. The
coupler control provides automatic or manual tuning and
impedance matching for the RF signal to the antenna.

RCU
The C-11329 RCU can be used with any system configuration
to provide remote operations capability. The three modes of
operation are RS-232, RS-422, and modem. Remember that for
control mode, audio interface, and modem interface selections,
the transceiver/remote control cable wiring must agree. A brief
description of each remote mode follows.
• The RS-232C mode of remote operation is an unbalanced
control line in a digital format useful for direct wire control
at ranges up to 100 feet.
• The RS-422 mode of remote operation is a balanced control
line in a digital format useful for direct wired control at
ranges up to 1 mile.
• The modem mode of remote operation is an analog
Frequency Shift Keying (FSK) format for use over standard
telephone lines/network at unlimited distance.
The remote control interface assembly must be installed in the
transceiver for remote operation. Determine the modes of
remote operation by selecting the appropriate mode on the
remote control assembly in the transceiver and the
audio/microprocessor assembly on the RCU.
In remote operation, control the transceiver by using the front
panel keypad on the remote control. The operator can make
frequency, channel, and mode selections from the keypad (of
the RCU). The remote control can access transceiver memory
that can store up to 100 channels of frequencies and operating
modes. The operator may also adjust analog controls on the
remote control front panel to set audio/RF gain levels, audio
squelch level, and audio input level of the transceiver.

SUMMARY
The URC-119(V) operates in the HF range from 1.6000MHz to
29.9999MHz and is tunable in 10Hz increments. It operates in
USB, LSB, AME, CW, and AFSK. AFSK is optional and
requires AFSK card installation. Tuning the URC-119(V) is a
fairly simple two step process: select the window frequency
and key the radio. The rest of the tuning process is done
automatically.
The URC-119(V), Pacer Bounce, can be configured for
100/500/1000W power outputs. The most common
configurations are 100W and 500W setups. The RT-1446
transceiver, along with the CU-2310 Antenna Coupler, make up
the 100W configuration. Adding the AM-7223 RF amplifier
boosts the output to 500Ws. The 1000W configuration is a little
different from the other setups. The AM-7223 RF amplifier and
CU-2310 antenna coupler are replaced by the AM-7224 RF
amplifier, PP-7913/URC Power Supply, and URA-38 Antenna
Coupler.
The C-11329 RCU can be used with any of the system
configurations. For remote operation, it must have the Remote
Interface Card installed in the RT-1446 transceiver. The RCU
front panel and keypad are identical to that of the RT, which
allows the operator to access all functions available to the RT
front panel. When remoting the RCU, make sure the mode
selection switches on the interface cards are set for the same
mode of operation.

MODULE 2
RT-1446 TRANSCEIVER OPERATION
ABOUT THIS MODULE
This module covers the different operating modes and functions
used by the RT-1446 transceiver. Since the transceiver can be
operated with a variety of ancillary equipment, it is the
responsibility of the user to configure the equipment to support
the intended operations.
PREREQUISITE(S)
Must have completed Module 1 of this AFQTP.
OBJECTIVE(S)
Given TO 31R2-2URC-81, operate the RT-1446 Transceiver
IAW pgs 3-1 thru 4-26. (AFJQS TASK 201.14.1.1)
• Explain the RT-1446 transceiver controls and indicators.
• Explain the transceiver modes of operation.
TRAINING REFERENCE(S)
TO 31R2-2URC-81
RT-1446 CONTROLS AND INDICATORS
POWER APPLICATION AND WARM-UP
The RT-1446 is solid state equipment and requires no warm-up,
although a 30-minute warm-up may be required for stabilization
of the frequency standard if it is operated after being in cold
storage. However, operations may be started before the warm-
up period provided you remember T/R frequency errors may be
experienced until stabilization occurs.
ANALOG CONTROLS POSITIONING
Use the analog controls (AUDIO GAIN, RF GAIN, and
SQUELCH) to set up the transceiver for comfortable listening
and signal detection. A brief discussion of each control follows.
• AUDIO GAIN. This control affects the front panel speaker,
headset, and handset. The audio outputs available at the
rear of the transceiver have separate level adjustments. If
the supplied headset is connected to the front panel
HEADSET jack, the front panel speaker is not disconnected.
Page 2-2, STM 2E1X3-206N
If desired, use the front panel switch to disconnect the
speaker.
• RF GAIN. This control is typically placed in the high gain
position, i.e., turn the knob fully clockwise. In this position,
the RF gain of the receiver is determined by normal
Automatic Gain Control (AGC) action. If a condition exists
where normal AGC action is detrimental to reception, turn
the RF GAIN control counterclockwise. The RF GAIN
control then overrides the normal AGC circuit, and
manually adjusts the gain of the receiver.
• SQUELCH. This control is usually placed in the OFF
position. This enables all receive signals to be monitored
regardless of signal strength. If it is desired to monitor only
a received signal that is strong enough to rise above the
background noise, enable the squelch function. If
SQUELCH is desired, find the correct setting of the
SQUELCH control by turning the squelch knob out of
detent in the clockwise direction during a period when only
background noise is present in the speaker. Turn the
SQUELCH control slowly clockwise until the squelch
action just mutes the audio output. An incoming voice
signal, above the noise level, breaks the squelch and can be
heard in the front panel speaker. Squelch action affects the
PATCH and AUD2 audio outputs as well as the front panel
speaker. The LINE receive audio output is not affected by
the squelch circuit. It is important to remember that the
squelch responds only to VOICE signals.
CONTROL OPERATION DURING TRANSMIT
Frequency and channel changes cannot be made when the
transceiver is keyed. Only the controls TEST, S TONE (there is
no front panel display for sidetone), and CLIP (used in voice
modes only) are active when the transceiver is transmitting. A
keyline inhibit signal prevents equipment damage during
frequency and channel changing operations and accidental
keying of the transceiver.
FREQUENCY SELECTION
The frequency range of the transceiver and all associated
ancillary equipment is in the HF spectrum (1.6MHz to
29.99999MHz). In CW mode, a 1kHz offset is entered in the
transmitted frequency. Accomplish frequency selection either
by scrolling or entering the number via the front panel keypad.
STM 2E1X3-206N, Page 2-3
CHANNEL SELECTION
Channel selection (another way to select a different frequency)
is done by programming frequencies into the radio. Up to 100
channels may be programmed. This information remains in
memory after the transceiver is powered off due to an internal
lithium battery. Press the memory erase button at the rear of the
transceiver to clear the memory. This clears all programmed
channels and last parameter information.

transceiver before the 30-minute warm-up has elapsed?
2. What does the AUDIO GAIN control affect?
3. When would the RF GAIN control be adjusted?
4. How is the channel memory cleared?
MODES OF OPERATION
There are five operating modes. To access each mode, turn the
MODE switch to the desired mode. For USB and LSB modes,
the carrier is fully suppressed. The AME mode is USB plus
carrier, and the CW mode is audio derived with a plus or minus
1kHz carrier frequency offset depending on whether CW-LSB
or CW-USB has been internally selected. For AFSK mode
selection, the AFSK option must be installed.
• USB and LSB Operation. The SSB, USB, and LSB modes
operate with a suppressed carrier. The bandwidth of the
SSB filters is 350Hz to 3050Hz.
• AME Operation. AME operates with carrier and USB. The
carrier is normally 25 watts, but the PEP resulting when
modulated is a full 100Ws. The IF filter for the AME mode
is the same filter used in the USB mode; it has a bandwidth
Page 2-4, STM 2E1X3-206N
of 350Hz - 3050Hz. AME is also known as compatible
AM.
• CW Operation. CW mode (MORSE) is full carrier
transmission without modulation. A frequency offset of
exactly 1kHz automatically results in transmissions 1kHz
above or below the displayed frequency. An internally
adjustable CW hang-time determines the amount of time
that elapses following the last transmitted CW character
before the transceiver switches to receive mode.
• AFSK Operation. It is important to adjust the AFSK
equipment at each end of the radio link for the same
sideband, center frequency, and frequency shift. It must
also have the AFSK option installed in the radio. The
AFSK option has an 850Hz shift with a center frequency of
2000Hz, a 170Hz shift with a center frequency of 2000Hz,
or an 85Hz shift with a center frequency of 2805Hz. Each
of these shifts can be used in LSB and USB. Make shift and
sideband selections at the AFSK Configuration Switch
located on AFSK IF Filter A1A18A2.
An indication of correct tuning of an AFSK received signal may
be obtained by using the AFSK meter function. When receiving
a correctly tuned AFSK transmission, the AFSK meter segment
should be positioned over the central arrow shown on the meter
scale. If this is not the case, the operating frequency of the
transceiver may be changed using the scroll keys until the
correct center indication is obtained.
If sufficient receive signal is not present at the input of the
AFSK module for reliable error free operation, the unit forces a
mark-hold condition to the teleprinter. In certain circumstances,
high receive noise levels may cause the mark-hold to be
released and the teleprinter to print randomly. To stop this,
reduce the RF GAIN control on the front panel until the
teleprinter is forced back into a mark-hold condition.
The normal sense is where a (+) = binary 0 = space, and (-) =
binary 1 = mark. If Keyer Reverse for transmit (KREV) or
Converter Reverse for receive (CREV) is selected, the
respective sense is reversed with (+) = binary 1 = mark, and (-)
= binary 0 = space.
It is possible to compensate at the transceiver for other AFSK
center frequencies by adjusting the operating frequency of the
100W transceiver by the amount of the difference. The
procedure uses the AFSK Relative Center frequency meter scale
where the distant party transmits a series of "RY" characters
STM 2E1X3-206N, Page 2-5
and the receiving party observes the AFSK meter. The
frequency of the transceiver is then adjusted to zero out any
offset.
AUDIO SOURCE SELECTION
In CW and AFSK modes, AUDIO SOURCE has no effect. In
the other modes, when AUDIO: MIC is selected as the audio
source, the microphone audio and push-to-talk keyline
information are from the front panel HANDSET/MIC
connector.
A compression circuit, in series with this input, automatically
compensates for variations in input levels of ±15dB. The input
is designed for use with a dynamic microphone, and carbon type
microphones cannot be used.
AUDIO: AUD2 accepts audio and push-to-talk keyline
information from the rear panel AUD2 J4, such as a KY-65.
There is no compression circuit associated with the AUD2
input, and it is designed to accept a 0dBm average power
speech signal from a 600-ohm source. The sensitivity of the
AUD2 input is adjusted internally.
AUDIO PATCH is used when connection to a 2-wire or 4-wire
telephone is necessary. There is no compression circuit
associated with this input. Both the incoming and outgoing
phone patch audio levels are metered and adjusted via front
panel controls.
AGC SELECTION
There are four options of AGC: AGC OFF, AGC SLOW, AGC
MEDIUM, and AGC FAST. The decay time is slow, medium,
or fast. When a mode of operation is selected, an AGC speed is
automatically selected typical for operations in that mode.
AGC has no affect if the AGC indicator reads AGC OFF.
VOICE OPERATED TRANSMIT (VOX) SELECTION
Use VOX to automatically generate a keyline when transmit
audio is detected. There is a choice of 2 VOX decay time
constants: a long decay for voice signals and a short decay for
data signals. The voice time constant is internally adjustable.
There are two front panel adjustments for the VOX circuit:
VOX and ANTIVOX. The VOX adjustment sets the threshold
level required to trigger the VOX circuit. The ANTIVOX
circuit samples the received speaker audio and counteracts the
effect of the microphone picking up the receive audio signal,
thereby preventing false VOX operation. Adjust the ANTIVOX
Page 2-6, STM 2E1X3-206N
only when the microphone is in a fixed position. VOX VOICE,
VOX DATA, and VOX OFF are the choices available.
BFO SELECTION
Use the BFO to raise or lower the pitch of received audio
signals in all modes except AME. There is no frequency read-
out of the BFO offset. The BFO does not change the pitch of
the received audio signals when operating in the AME mode.
The maximum BFO offset is 1000Hz. BFO offset is entered
with scroll keys with a change of 10Hz per keystroke.
CLIP SELECTION
The CLIP function is selectable only in voice modes from the
MIC and PATCH sources. Use this feature for peak clipping of
the transmit audio levels to increase the average RF output
levels. The clipper is adjustable internally from 0dB to 12dB.
SIDETONE SELECTION
Use the sidetone feature to inject a portion of the transmit audio
into the receive audio path. This is useful for the operator in
voice modes for headset feedback, in CW mode for a 1kHz tone
when the CW key is closed, or to monitor the transmit audio
during any mode of operation. There is no indicator for
sidetone function, and it is automatically selected when
operating in the CW mode.
FSK REV SELECTION
The FSK REV function is selectable only in the AFSK mode.
This feature is used to reverse the sense of the AFSK keyer
(KREV), the AFSK Converter (CREV), or both.
TX KEY SELECTION
The TX KEY function is selectable in all modes of operation.
This feature may be used to generate a keyline whenever the
normal keyline is absent, or to enable transmit BIT for test
procedures, etc. In the CW mode, a CW key closure is also
required to obtain output power. (The transmit key is selected
and the CW key is also closed.)
FRONT PANEL LEVEL ADJUSTMENTS
There are two front panel adjustments for the VOX circuit:
VOX and ANTIVOX. The VOX adjustment sets the threshold
for the audio level required to trigger the transmitter keyline.
The ANTIVOX circuit is there to prevent the receive audio
from keying the radio.
STM 2E1X3-206N, Page 2-7
To set the VOX threshold, connect MIC to the front panel jack
and speak into the microphone. Adjust the VOX potentiometer
until the transmitter keys. To align the ANTIVOX circuit, start
by selecting the VOX feature. With no audio, adjust the
ANTIVOX potentiometer counterclockwise until the transmitter
keys. When this happens, turn the ANTIVOX clockwise until it
unkeys. The VOX and ANTIVOX adjustments interact with
each other so you may have to repeat several times to suit your
needs.
Use PATCH RCV and PATCH XMIT maintenance controls to
set the levels to and from 2-wire/4-wire external telephone
patch connections, respectively. Use TB1 on the rear of the
transceiver to establish phone patch circuits. A telephone line is
provided for use. If the line provider does not know whether
the line is 2- or 4-wire, you have to figure it out. Most
telephone lines are 2-wire; therefore, you should connect the
telephone lines to TB1-2 and 3. If you have a 4-wire phone
line, use TB1-1 through 4. The polarity of the 2-wire line does
not matter. However, when using a 4-wire line, you cannot mix
the line IN with the line OUT. This means there are two wires
for receive and two wires for transmit. The polarity of the
transmit and receive lines does not matter. However, you
cannot connect a receive line with a transmit line or vice versa.
Another important thing to remember is that the screws on TB1
are fragile. Take care when connecting wires to the terminal
board.
The normal adjustment of the PHONE RCV is such that voice
peaks observed on the PATCH meter are -10dBm. This level
may be adjusted upward if the phone user reports weak received
audio. The purpose of the PATCH function is to allow a user to
operate the radio using a telephone. You must key the radio
unless VOX operation is used.
The MIC control is active when the audio source is MIC. The
MIC control adjusts the input transmit audio levels. 0dBm is
the normal setting. Anything above that causes excessive noise
to be transmitted during speech pauses.
Use line adjustments when equipment other than the RCU is
used with the transceiver. The adjustment allows you to set the
line level anywhere from -20 to +10dBm. The RCU is
connected to the transceiver via J9 and has internal adjustments
for the line.
Page 2-8, STM 2E1X3-206N
METER EXPLANATIONS
The "S" scale gives an indication of received signal strength and
ranges from S3 (-100dBm) to +60dBm. This scale is
automatically selected when in the receive mode and the meter
is set to FWD, REF, or VSWR.
The AUDIO meter gives an indication of transmit audio signal
strength. The scale ranges from -20dBm to +10dBm. The
nominal level is 0dBm.
The LINE meter gives an indication of the receive line audio
signal or the remote line input signal when keyed. The scale
ranges from -20dBm to +10dBm.
The PATCH meter gives an indication of the PATCH input
signal (TX) or PATCH output signal (RX). The meter
indication for XMIT occurs when the transceiver is keyed. The
scale is from -20dBm to +10dBm.
The FWD meter gives an indication of forward output power of
the transceiver. The scale is from 0 to 150 Watts. With the 500
or 1000W LPA connected, the scale is multiplied by 10. It also
gives an indication of received signal strength because the "S"
scale is automatically selected when the FWD meter is selected.
The REF meter gives an indication of the transmit reflected
power. The scale is the same as the FWD.
The VSWR meter gives an indication of the VSWR. The scale
ranges from 1 (1:1) to 4 (4:1).
The AFSK meter shows relative center frequency with an arrow
indicating midscale and a bar showing offsets to the left or
right. This meter reading is correct only when the average mark
and space signals of the incoming signal are equal. A steady
mark or space does not yield an accurate reading.
PROGRAMMING CHANNELS
The transceiver has the capability of storing 100 frequencies
and their operating parameters. This is done using the PROG
and LOAD functions on the keypad. After a channel is
programmed, the transceiver displays the operating conditions
that were set before programming started.

SUMMARY
Set operating parameters for the RT-1446 by using the front
panel controls and keypad. Three Analog Control knobs (Audio
Gain control, RF Gain control, and Squelch control) allow you
to adjust the RF and audio levels at several different stages in
the receive process. Select frequencies by either scrolling or
entering numbers via the keypad. Up to 100 channels may be
Page 2-10, STM 2E1X3-206N
stored in the RT's memory. You can choose from LSB, USB,
AME, CW, and AFSK for modes of operation. The AFSK
mode is an option that must be installed. When Audio Source is
selected you are given three choices: MIC, AUD2, and Audio
Patch. However, this selection does not affect the CW or AFSK
modes because they contain no audio. There are four AGC
options to choose from: AGC OFF, AGC SLOW, AGC MED,
and AGC FAST. Other settings selectable from the front panel
keypad are the BFO for receive, CLIP function for transmit
MIC and PATCH audio inputs, Sidetone, FSK REV, and the
TX KEY selection. FSK REV is selectable with the AFSK
mode.
As a radio technician, it is imperative to know the function of
each control and indicator. The RT-1446 transceiver has many
capabilities. Knowing what they are and how to apply them
gives you the confidence to be a better technician.

C-11329 REMOTE CONTROL UNIT (RCU) AND
CU-2310 ANTENNA COUPLER OPERATION
ABOUT THIS MODULE
This module covers the RCU and Antenna Coupler connections
and operation.
PREREQUISITE(S)
Must have completed Modules 1 and 2 of this AFQTP.
OBJECTIVE(S)
Given TO 31R2-2URC-91, operate C-11329 RCU IAW pgs 3-1
thru 4-26. (AFJQS TASK 201.14.1.2)

C-11329 RCU OPERATION
The RCU is normally used when the transceiver and antenna
coupler are collocated at a different location than the RCU. The
different configurations used with the RCU were briefly
discussed in Module 1.
RCU CONNECTION
Refer to TO 31R2-2URC-91, Figure 2-5, for RCU rear panel
connections and to TO 31R2-2URC-81, Figure 4-1, for
transceiver rear view. Figure 3-1 in this module shows all
possible connections for the RCU. Follow these steps for
configuring, and there should be no problems.
Page 3-2, STM 2E1X3-206N
• Verify that the RT has the Remote Control Interface
Assembly, and if it does not, install one.
• Connect the power cable to the RCU, but do not plug it into
the power source yet.
• Connect J2 on back of the RCU to J9 of the transceiver.
This connection provides interface between the two units.
• Ensure all switch settings on the RCU and transceiver
correspond by removing the covers of each unit and setting
the switches. If the two units are to be separated by a great
distance, set the switches before separating the units.
Figure 3-1. RCU Equipment Connections
STM 2E1X3-206N, Page 3-3
CONTROL MODE SWITCHES
Accomplish control mode selection via switch S4 located on
Audio/Microprocessor Assembly (A2) in the remote control,
and at the transceiver by using switch S2 located on A1A19
Remote Control Interface Assembly. These two switch
positions must match for the unit to operate correctly. The
status of these switches is only read during power up; therefore,
changing the switch positions while the equipment is running is
not recognized. In other words, the units must be turned off
during switch selection.
BAUD RATE SWITCHES
Control is possible at a variety of baud or data rates ranging
from 300 to 9600 baud. Use the 300 baud rate in the modem
mode. In other modes, the 9600 baud rate is generally selected
since the higher data rates provide a more rapid response to
remote commands.
Make baud rate selection via two switches. The first switch, S3,
is located on Audio/Microprocessor Assembly (A2) in the
remote control. The second switch, S1, is located on A1A19
Remote Control Interface Assembly installed in the transceiver.
The baud rate settings must be the same on both assemblies for
proper operation. Again, the status of these switches is only
read during power-up.
AUDIO INTERFACE SWITCHES
The audio interface may be either 2- or 4-wire. Use the 2-wire
configuration when interfacing with standard telephone
lines/networks or when it is desired to minimize the number of
wires between the RCU and transceiver.
Select the audio interface via two switches. The first switch,
S2, is located on Audio Interface Assembly (A4) in the RCU.
The second switch, S2, is located on Audio Interface Assembly
(A1A16) in the transceiver. The switch settings must match for
correct equipment operation.
MODEM INTERFACE SWITCHES
The modem interface may be either 2- or 4-wire. As with the
interface switches, use the 2-wire configuration when
interfacing with standard telephone lines/networks or when it is
desired to minimize the number of wires between the RCU and
the transceiver. Otherwise, use the 4-wire configuration.
Select the modem interface via two switches. The first switch,
S5, is located on Audio Microprocessor Assembly A2 in the
Page 3-4, STM 2E1X3-206N
remote control. The second switch, S5, is located on Remote
Control Interface Assembly A1A19 in the transceiver. The
switch settings must match for correct equipment operation.
RCU OPERATION
As previously mentioned, operation of the RCU is identical to
the transceiver, but with one exception. The only difference is
the AFSK mode, which cannot be operated via the RCU. The
RCU has the same keypad as the transceiver, and all functions
are the same as the transceiver. This completes our discussion
of RCU operation.

CU-2310 ANTENNA COUPLER
Use the CU-2310 Antenna Coupler with the transceiver in the
100 or 500W configuration. It automatically matches the output
impedance of the transceiver or RF amplifier to an antenna over
the frequency range of 1.6 to 30MHz. Refer to Figure 2-2 in
TO 31R2-2URC-111 for coupler connections.
CU-2310 ANTENNA COUPLER CONNECTION
As you can see from the figure, it is simple to set up the antenna
coupler. Start with the RF coaxial cable; it connects to (J1) on
the RT in 100W mode. In the 500W configuration it connects
to (J5) on the RF Amplifier. The control cable (supplied with
the coupler) always connects to the transceiver. There are no
power connections for the coupler; however, it must be
grounded. The last step in hooking up the coupler is connecting
the antenna wire to E1.
CU-2310 ANTENNA COUPLER OPERATION
Once the coupler is properly connected, operation is controlled
by the transceiver (or RCU, if used) and is fully automatic.
The CU-2310 Antenna Coupler receives power from the
transceiver. The power switch on the transceiver front panel
controls power to the antenna coupler.
To operate the antenna coupler, tune the transceiver to a specific
operating frequency and momentarily key the unit. The antenna
coupler can be heard driving to the HOME position. If nothing
is heard, a fault code should display, or the coupler may already
be tuned. If no faults appear, consider the antenna coupler
operational. This concludes our discussion of the operation of
the CU-2310 Antenna Coupler.

SUMMARY
The RCU and the transceiver have several switches that must
correspond to each other for proper equipment operation.
Audio/Microprocessor (A2), located in the RCU, is home to all
but one of the switch settings. It houses switches S4 Modem
Control, S3 Baud Rate, and S5 Modem Interface. These switch
settings must match those of S1, S2, and S5 located on Remote
Control Interface PWB Assy (A1A19) in the transceiver. The
other switch setting is the Audio interface switch, located on
Audio Interface Assy (A1A16) in the transceiver and the A4
card in the RCU. Operation of the RCU is the same as the RT
with one exception; you cannot access the AFSK mode in the
remote setup.
The CU-2310 Antenna Coupler can be used in the 100 and
500W configurations. The transeiver supplies power to the
coupler. The front panel keypad or the RCU controls the
antenna coupler when in remote configuration. To tune the
coupler, select a frequency and momentarily key the radio.

ABOUT THIS MODULE
This module covers the operation of the two LPAs and takes a
look at each control on the front panel of the amplifiers. The
operation of the AM-7223 and 7224 LPAs is similar with a few
exceptions. These similarities may remind you of the RCU and
antenna coupler operational procedures presented in an earlier
module. To assist in troubleshooting the equipment, it is
important to know the operational procedures.

AM-7223 LPA DESCRIPTION
PURPOSE
The AM-7223 LPA is a microprocessor-controlled power
amplifier that amplifies the selected HF input signal from the
RT-1446 in the 1.6 to 30MHz. It delivers 500Ws PEP with
Page 4-2, STM 2E1X3-206N
multiple tone input signals, or 250 watts average with lock
keyed CW or a continuous single tone input signal. The LPA
tunes automatically, in 10 seconds or less, in response to
frequency data from the 100W Transceiver and to its own
internally generated servo signals. It can also be manually
tuned using the front panel controls.
The 500W LPA is usually operated in the auto mode of
operation. During power-up, the circuit breakers on the rear
panel must be on and the POWER ENABLE/OFF switch on the
front panel in the POWER ENABLE position. Since the
1000W LPA is operated with the PP-7913 Power Supply, the
POWER ENABLE/OFF switch needs to be in the POWER
ENABLE position.
If either LPA has been turned off for more than 10 seconds,
there is a 3 minute warm-up period before the LPA can be
placed to OPERATE. During this time, the manual controls
(such as TUNE PWR and LOCAL KEY) are disabled. The
STANDBY LED on the LPA flashes during the warm-up
period and remains steady after the warm-up period.
PROCEDURES
TO 31R2-2URC-101, Figures 1-1 and 2-5 and Table 3-1,
illustrate the AM-7223 LPA controls, outputs, jacks, and initial
control settings. Let's take a look at these controls, starting with
the initial control settings.
INITIAL CONTROL SETTINGS
Initial control settings establish standard positions with which
further operations can be made. Ensure all controls are in the
proper position before attempting to operate the unit. Table 3-1
lists the initial control settings for the AM-7223 LPA.
STEP-BY-STEP SEQUENCE FOR POWER
APPLICATION
Before applying power to the LPA, ensure the LPA is connected
to its associated ancillary equipment. Remember, operation
with a transceiver is an absolute must.
• Once the LPA is connected, begin the power application
sequence by completing the associated transceiver power
application checks. Make sure the transceiver has passed
the BIT.
• Verify the power source for the LPA matches the input
power requirements.
STM 2E1X3-206N, Page 4-3
• Set the POWER ENABLE/OFF switch to the ENABLE
position. This allows the LPA to be powered on at the
transceiver by pressing 2ND AMP PWR. If the LPA has
been off for more than 10 seconds, there will be a 3 minute
warm-up period upon power application before the LPA
goes into the OPERATE mode. The STANDBY indicator
on the LPA flashes during this 3 minute warm-up and
becomes steady after the warm-up time has expired.
STEP-BY-STEP SEQUENCE FOR MANUAL BIT
PROCEDURE
Before performing this procedure, make sure the applicable
antenna coupler is tuned. When performing the manual BIT
procedure, do test initiation with the LPA, not with the
transceiver; however, the transceiver must be connected. To
initiate BIT:
• Set the AUTO/MANUAL switch to the band corresponding
to the frequency selected on the associated transceiver
(bands begin at 0000 and end at 9999).
• Rotate the METER switch to the STATUS/FAULT
position. If the METER switch is not in the
STATUS/FAULT position, the self-test cannot be initiated
at the LPA.
• Press the SELF TEST button (the white push button) on the
LPA front panel.
• If any fault codes are indicated, refer to the fault
isolation portion of the TO for the fault code definition
and procedure for correcting the fault condition.
• If no faults exist, a "PASS" message appears on the
METER display.
• After the test cycle is complete, move the METER switch
out of the STATUS/FAULT position to remove the LPA
from the test mode.
STEP-BY-STEP SEQUENCE FOR AUTOMATIC BIT
PROCEDURE
Initiate the automatic BIT procedure via the transceiver. Clear
LPA faults the same way as in the manual BIT procedure. To
initiate an automatic BIT from the transceiver:
• Power up the LPA by depressing 2ND/AMP PWR.
• After a 3 minute warm-up time, press the 2ND/STB OPR
buttons.
• Momentarily key the transceiver for tuning the LPA.
• Press 2ND/KEY 2ND/TEST.
Page 4-4, STM 2E1X3-206N
• When the BIT test is completed, press 2ND/KEY again to
unkey the transceiver.
• If there are no faults, a "PASSED" message appears on the
transceiver display. This indicates all equipment connected
passed the BIT.
• If any of the fault codes (2-01 through 2-22) are seen on the
display, there is a problem with the LPA. To display a fault
code on the LPA’s LCD display, place the METER switch
to the STATUS/FAULT position. You can clear the fault
code by commanding the LPA amplifier to operate from the
transceiver or by moving the LPA’s METER selector
switch out of the STATUS/FAULT position. However, if a
fault condition still exists that affects the operation of the
LPA, the LPA fault indicator lights and the LPA go into the
BYPASS mode. This means the transceiver output is
routed directly to the coupler or antenna, whichever the
case may be.
STEP-BY-STEP SEQUENCE FOR MANUAL TUNING
PROCEDURE
Use this procedure to check the manual tuning capability of the
LPA. Refer to TO 31R2-2URC-101, Figure 3-1, as we cover
this procedure.
• Connect the equipment to the system configuration at your
location.
• Set the transceiver to the desired operating frequency.
• At the LPA, select the band corresponding to the selected
transceiver frequency using the AUTO/MANUAL BAND
switch.
• Place the METER selector switch to the COIL POS
position.
• Using the TUNE control, preposition the coil to the value
indicated on the manual tune chart (the number will be
observed on the LPA’s LCD display).
• Look at the "frequency" portion of the chart and find the
transceiver frequency.
• Move up to the range line, and then left to the coil
"position" line. This gives you the number that
corresponds to the coil position for that particular
frequency. These coil position segments are 100 points
apart, so approximate the frequency if it falls between
points, e.g., between 600 and 700 on the coil position
scale.
• Once the coil is tuned, set the METER switch to either the
FWD PWR (WATTS) or RF PLATE (VOLTS) position.
STM 2E1X3-206N, Page 4-5
• When the bandswitch has finished tuning the bandswitch
wafer, set the MANUAL TUNE PWR switch to the ON
position. This generates a TUNE POWER REQUEST to
the transceiver, and the LPA is keyed.
• If a fault is detected while this switch is active, the LPA
drops back to STANDBY, and before the fault can be
cleared, the MANUAL TUNE PWR switch must be turned
off.
• While observing the METER display, use the TUNE switch
to tune the servo coil for maximum meter reading.
• Turn off the MANUAL TUNE PWR switch. When the
MANUAL TUNE PWR switch is turned off, the transceiver
is notified that the LPA is tuned whether it actually is or not.
Therefore, before you turn this switch off, ensure you
correctly tuned the LPA. Otherwise, there is the possibility
of a severe mismatch between the LPA and antenna system,
thus resulting in a high VSWR and low forward power.
• Set the MANUAL LOCAL KEY switch to the ON position.
The LPA should go into the OPERATE condition, and the
OPERATE indicator should become a steady light.
STEP-BY-STEP SEQUENCE FOR AUTOMATIC
TUNING PROCEDURE
This procedure checks the ability of the LPA to automatically
tune from the transceiver front panel buttons. After connecting
the equipment:
• Turn the LOCAL KEY switch to OFF.
• Set the AUTO/MANUAL BAND switch to the AUTO
position. This deactivates all manual tune switches.
• On the transceiver, press 2ND STBY/OPR switch to place
the LPA in the operate mode.
• Select a different frequency band (one other than the one
used for the manual tuning procedure) and key the
transceiver. The LPA should tune to the new frequency in
10 seconds or less.
• If it does not tune to a new frequency, a fault code is
displayed on the transceiver LCD. If a fault code is not
encountered, the initial check-out procedure is
completed.
• If a fault code is encountered, refer to the trouble-
shooting portion (Chapter 6) of the appropriate TO.
AUTO/MANUAL BAND SELECTION
This front panel, ten-position, AUTO/MANUAL rotary switch
selects between automatic and manual mode of operation in the
Page 4-6, STM 2E1X3-206N
frequency band selected. In AUTO position, tuning is
automatic and controlled completely by signals from the
transceiver. In this position, the MANUAL TUNE, MANUAL
TUNE POWER, MANUAL LOCAL KEY, and self-test
controls are disabled.
When the AUTO/MANUAL BAND switch is not in the AUTO
position, the LPA is in the manual mode and the current
operating frequency band is selected. (Actually, you select the
operating frequency band with the AUTO/MANUAL BAND
switch.) The 500W LPA has nine operating bands and the
1000W LPA has 10 operating bands. Selecting a new switch
position causes the internal band switch wafer to turn to its
corresponding position. The wafer does not turn unless the
operator has left the band switch in one position for more than
one second. Then the microprocessor sends an RF mute signal
to the transceiver and unkeys the LPA. Also, the bandswitch
does not turn while there is RF power at the XCVR RF input of
the LPA. All manual tuning keys, along with the self-test
control, are disabled while the wafer is turning.
MANUAL TUNE POWER SWITCH
When manual operation is selected, the Manual Tune Power
switch is moved to the ON position. This sends a tune power
request message to the transceiver and keys the LPA. When the
Manual Tune Power switch is activated, any previous fault
indications are cleared. If a fault is detected while this switch is
active, the LPA drops back to STANDBY, and the Manual
Tune Power switch must be turned off before the fault can be
cleared. Activation of the tune mode causes the transceiver to
transmit a CW carrier emission.
MANUAL LOCAL KEY SWITCH
This switch keys and places the LPA in OPERATE when it is
turned on. Also, the switch is active only in the manual mode
and clears any previous fault indications when it is activated. If
this key is activated and a fault condition occurs, the LPA drops
back to STANDBY and must be deactivated before the fault
condition can be cleared. This switch keys only the LPA, so the
transceiver must be keyed independently.
MANUAL TUNE SWITCH
This switch is active only in the manual mode and allows the
operator to fine tune the LPA by controlling the position of the
tune variable coil.
STM 2E1X3-206N, Page 4-7
SELF TEST BUTTON
With the AUTO/MANUAL BAND switch in any position
except AUTO and the METER switch in the STATUS/FAULT
position, push the SELF TEST push button to initiate the BIT
for the LPA only. The BIT tests all functional modules and
displays failures on the meter display (of the LPA) when the
STATUS/ FAULT position of the METER switch is selected.
Other functions of this button are explained later in the BIT
interpretation section.
METER SELECT SWITCH
The METER select switch controls the inputs to the METER
LCD display. There are eleven possible functions for the LPA.
The details of each function were described in an earlier
module.
TRANSCEIVER CONTROLLED OPERATION
Automatic tuning of the LPA is controlled completely by the
transceiver when the AUTO/MANUAL BAND select switch is
in the AUTO position.
METER DISPLAY UPDATE
Periodically, the microprocessor reads the appropriate inputs
and calculates a new value for the METER LCD display. The
meter display routine is inactive during BIT. The analog inputs
are read every 100 milliseconds, and an average or peak value is
displayed every second for the function selected.

AM-7224 LPA ANTENNA LOADING SWITCH OPERATION
PURPOSE
The 1000W LPA has the capability for antenna loading
selection. The ANTENNA loading switch controls the output
impedance to the antenna for the 1kW LPA in MANUAL mode.
The 1kW LPA microprocessor controls the output impedance to
the antenna in AUTO mode. The manual ANTENNA switch
selects between LOW Z, 50 OHMS, and HIGH Z loading.
When a new ANTENNA switch position is selected in the
manual mode, the 1kW LPA microprocessor does not change
impedance until after an RF MUTE request is sent to the
transceiver and the 1kW LPA is unkeyed. This prevents
damage to the equipment.
PP-7913 POWER SUPPLY FUNCTION
The function and purpose of the PP-7913 Power Supply is to
supply AC and DC voltages to the AM-7224 LPA. The power
supply is a 115/208/230VAC, +10%, single-phase 50/60/400Hz
unit that produces three output voltages: +3000VDC at 1A,
+13.5VDC at 8A, and 115VAC at 1A. After proper
connections are made to the LPA, power is applied when the
PP-7913 power supply is turned on.

15. What is the purpose of the ANTENNA loading switch of the
1000W LPA?
16. What is the purpose of the PP-7913 power supply?
SUMMARY
As discussed throughout this module, the AM-7223 and
AM-7224 LPAs are the two RF amplifiers that connect to the
RT-1446. Both are microprocessor controlled amplifiers that
boost a 100W HF signal to either a 500 or 1000W output. They
have identical front panel controls and operate the same except
the AM-7224 LPA must have the PP-7913 Power Supply for
operation.
