1.4. Connection to Antenna &
Power Supply
The Eagle is designed for use with any
antenna system providing a 50 Ohm resistive
impedance at the desired operating frequency.
Every effort should be made to ensure the
impedance of the antenna system is as close
as possible to the specified 50-Ohm value.
Note: that the “G5RV” type antenna and
some Windom’s do not provide 50-Ohm
impedance on all HF Amateur bands, and an
external wide-range antenna coupler or the
optional model AT599K Eagle internal auto
tuner may be needed with this type antenna.
Any antenna to be used with the Eagle must,
ultimately, be fed with 50 Ohm coaxial cable.
The Eagle transceiver requires a source of
well-filtered and regulated DC voltage. The
supply voltage on the Eagle is 13.8 Vdc
nominal +/- 15% to allow for mobile and
battery operation. The voltage source must
be capable of supplying 23 amperes
continuous duty. The model 940 or 941 Ten-
Tec power supplies will meet or exceed your
voltage and current requirements. We
recommend using the included DC power
cable (P/N 46214). Use of #12 stranded wire
is recommended for mobile and in home use
to accommodate the required current demand
during transmit.
Note: Always enable the power source first
and then the transceiver. If a generator or
battery connected to a charger is used to
supply the DC source, always turn off the
transceiver before starting or shutting off the
DC source equipment. These recharging
devices often generate large voltage spikes
that can damage the transceiver.
1.5. A word about grounding
A good ground system is essential for
optimum operation of any HF transmitter.
The best solution is to connect all the station
equipment to a single ground connection.
Refer to Local and National Electrical Codes
before making any connections with the
Eagle. Another source of information on
grounding can be found in the ARRL
Handbook.
A good ground system can contribute to the
station efficiency in a number of ways
including minimizing the possibility of
electrical shock, and minimizing RF currents
flowing on the shield of the coax cable
causing interference to electrical equipment
and transceiver accessories.
It is critical that the power supply, the Eagle,
and other equipment in the station be properly
grounded to an Earth ground. Improper
grounding can lead to various issues,
including RFI, ground loops, or even death.
Therefore it is extremely important to refer to
the Local and National Electrical Codes and
ARRL Handbook with regards to grounding.

1.6. Philosophy of design
With the Model 599 Eagle, Ten-Tec has
created a transceiver combining simplified
controls and ease of operation with the
excellent performance of a low first IF 160-
through 6-meter ham-band architecture in a
compact, mobile-friendly structure. The
analog portion of the radio is double
conversion with IF frequencies of 9.0015
MHz and 22.5 kHz. A third conversion to
zero-frequency IF is accomplished in the DSP
processor.
General coverage receive is provided between
0.5 and 30 MHz.
Refer to the Block Diagram in the
“Specifications” section for the following
discussion. Receive signals are routed
through the optional antenna tuner and
transmit lowpass filter to a switchable 10dB
attenuator at the input of the BPF/Preselector
board. This board also contains the bandpass
filter selected for the band in use and a
switchable 12dB receive preamplifier. On the
TX/RX board, output from the preamplifier is
mixed with the first Local Oscillator to
9.0015 MHz and routed optionally through
the noise blanker to one of three roofing
filters. After selectivity roofing, IF
amplification is provided by a variable gain
amplifier which also develops the high-level
AGC. Finally, the 9.0015 IF signal is mixed
with the second LO to develop a 22.5 kHz
low IF for the Signal Processing Unit (SPU).
Based on a 36.096 MHz temperature-stable
reference, the Synthesizer board generates
first and second LOs via fractional-N
synthesis and fixed frequency division. The
SPU samples the low IF at 96K samples per
second and applies the resulting data to a
digital signal processor. Numerical
algorithms running in the digital processor
accomplish additional selectivity filtering,
low-level AGC, and demodulation. The
resulting audio appears at the speaker and line
outputs.
The PIC processor in the CPU module
executes firmware stored in EEPROM to
perform housekeeping functions such as
synthesizer programming/tuning, signal
switching, and front panel display and control
input. Based on the control inputs from the
front panel (or remotely via the USB
interface), the CPU writes display
information, tunes the LOs, adjusts
selectivity, and chooses both receiver
detection and transmit emission modes.
Transmit operation is basically the reverse of
receive. Audio or CW signals are generated at
zero-frequency (baseband) in the DSP,
frequency-shifted to the 22.5 kHz low IF, and
output to mixers on the TX/RX board for
conversion to the operating frequency. The
signal then travels in the reverse direction
through the selected Bandpass Filter to the
low-level drivers and Power Amplifier, then
finally through the Lowpass Filter and
optional antenna tuner to the antenna. If the
tuner is installed, forward and reverse power
measurements from the SWR bridge are used
by the CPU to select the correct inductance
and capacitance in an L-network to provide a
50 Ohm load to the transmitter output

1.7. Configuration Menu
Upon purchase of your transceiver some
settings may have already been factory
installed and set into the Eagle. Optional
accessories such as an auto tuner, a specific
additional roofing filter, noise blanker, or
your favorite front display color combination
will need to be programmed into the Eagle.
When optional items are shipped with your
Eagle order, then these optional items will
already be configured at the factory in the
Configuration Menu.
To begin configuring the Eagle, start with the
Eagle powered off, press the FNC button, and
continue to hold the FNC button while
powering up the Eagle. When the Eagle is
first shipped from the factory, the front panel
display will show “F1 2.4” which indicates
the factory filter has been installed. Now
release the FNC button. To select a different
value for a given Configuration Menu item,
use the MULTI knob to scroll through the
choices. To advance to the next Configuration
Menu item, press the FNC button. Once the
settings in the Configuration Menu have been
set to the desired values, press any key on the
front panel except the FNC button to exit the
Configuration Menu.
The items contained in the Configuration
Menu and their options are shown in the
following table.

2. Easy Operation Guide
2.1. General Operations
This section of your Eagle Manual will
discuss the button operation and adjustments
common to all modes on the Eagle
Primary and Secondary Button
Functionality
Most buttons on the front panel can perform
multiple functions. The Primary Function for
the buttons on the Eagle is screened directly
on the button. They are lit when power is
applied to the radio. The Secondary Function
for the buttons is silk-screened above the
respective button on the front panel. The
FNC button is used to invoke the Secondary
Functions of the front panel buttons. The
functionality for both Primary and Secondary
buttons are described in the following
sections.
Master Reset (using LOCK (15) button)
To perform a master reset to the Eagle, begin
by pressing and holding down the LOCK
button at the same time you turn on the
power. Continue to hold down the LOCK
button until the screen says “reset”.
You have now performed a reset to the Eagle
which will also clear all memories and
settings you have placed in your transceiver.
Performing a reset means you will need to
enter the Configuration menu described in
Advanced Settings to program your filter
positions, accessories, screen colors, etc.
Keying a Linear Amplifier
Pin 8 on ACC-1 will provide an open
collector output for keying a linear amplifier.
The Eagle provides a 17 ms closure delay
before RF is supplied to the linear amp.
Refer to Figure 3-2 for wiring to this
connector. Remember to use shielded cable
for making this connection. The amp key line
is not a relay similar to those found on many
older transceivers. It is a transistor switch
rated for a maximum of 24 volts and 250 mA
from the key line of your amplifier. Many
older amplifiers using an AC relay or relay
voltages exceeding the limits of the Eagle
must use an amplifier interface relay such as
the ARB-704 sold through the Ten-Tec
company P/N #R9901
S-Meter
The meter on the Eagle offers two functions:
1. S-Meter, in receive mode, the meter
shows the signal strength.
2. SWR-Meter, while transmitting or in
TUNE mode, the meter shows the
SWR as calculated on the bridge in
the Eagle.

FNC (12)
The FNC button is a vital portion of this
radio. All Secondary Functions of the Eagles
button set are accomplished by pressing the
FNC button. When the FNC button is first
pressed, the FNC button will begin flashing.
This is referred to as Entering Secondary
Function Mode. You will also see FUNC
blinking on the main screen where the
Bandwidth Value is normally displayed.
Pressing a button using the Secondary
Function will execute the secondary function
for that button. Either turning it on or off, or
changing its mode, etc. Pressing the FNC
button once again will exit that secondary
feature adjustment as well as Exiting
Secondary Function Mode.
PWR (24)
Power output will be shown on the Eagle
toward the left side of the display. It displays
the output in watts and can be adjusted and
shown as a numeric value from 5-100. To set
the power output first Enter Secondary
Function Mode and then press TUNE/PWR.
The multi knob can now be used to adjust the
output. After the power output has been
selected you may exit FNC mode and PWR
adjustment mode by pressing FNC.
TUNE (25)
If the auto tuner for the Eagle is not turned on
or is not installed this button will generate a
carrier signal for tuning purposes at 20 watts.
This is providing the power output is set at a
minimum of 20 watts. If set lower, it will
transmit a lower level carrier. If the power
output is set anywhere from 20-100 watts the
Eagle will still only tune at 20 watts. This is
an easy and safe way to tune an external
outboard antenna tuner or solid state
amplifier. To increase this power output level
while in the tune positions Enter Secondary
Function Mode and then press TUNE/PWR
again. You may now adjust the power level
using the MULTI knob to vary the output for
tuning a linear amplifier.
If the auto tuner is installed and turned on in
the Configuration Menu the TUNE button
will now automatically match the Eagle to the
antenna you are using. You will hear some
clicking noise within the Eagle until the tuner
determines the best match. When finished the
TX light will flash twice plus you will hear a
beep tone from the Eagle. Remember when
using an external tuner or when tuning a
linear amplifier to always go into the
Configuration Menu and turn off the internal
auto tuner. With the internal tuner enabled in
the configuration menu, you can place the
tuner into bypass mode, or return it to the
current tuned settings. Refer to the section
“Internal Tuner” for more information.

values. More about this will be addressed
within specific features throughout this
manual.
Band (21)
To change bands or toggle through the Ham
bands press the BAN button and the next
Ham band will be recalled. Using the BAN
button when Secondary Function Mode is
active changes bands to the next lower Ham
band. Using the BAN button when the
Secondary Function Mode is not active
changes bands to the next higher Ham band.
When the band is changed, the A Frequency,
the B Frequency and the Mode are recalled
from the last time the band was used. Since
the Mode is recalled, the Tuning Rate, and the
AGC will also be recalled from the last time
that Mode was used.
Split (28)
To operate SPLIT mode press and hold the
A/B button for 2 seconds. The word SPLIT
will appear next to the VFO B. VFO B now
indicates the transmit frequency. To exit
SPLIT mode, press and hold the A/B button
until the word SPLIT disappears.
A/B (28)
This Primary Function allows you to toggle
the frequencies between VFO Aand VFO B
each time you press the button.

VFO B. To copy the frequency of VFO A to
VFO B, Enter Secondary Function Mode then
press the A/B/A=B button. Exit Secondary
Function Mode by pressing FNC.
RIT (22)
The Receiver Incremental Tuning can be
selected, adjusted, and zeroed. Enter Receiver
Incremental Tuning adjustment by first
Entering Secondary Function Mode then
press the MOD/RIT button. You will notice
RIT will begin to flash on the front panel.
You may now adjust the receiver in 10 Hz
increments up or down frequency using the
MULTI knob. The absolute value of the
actual RIT is displayed where the bandwidth
is normally displayed. There is a “+” and “-“
indicator next to the RIT indicator on the
display to identify whether the RIT
adjustment is actually positive or negative. To
zero out the RIT simply press and hold the
MOD/RIT button while in FNC mode and the
display will zero out. Exit Secondary

frequency, press the LOCK button once to
lock the VFO. Press the LOCK button a
second time to release the lock feature. Lock
state is indicated by the text on the right side
of your screen when turned on.
Switching to Memory Operation (7)
Pressing the V/M button activates the
memory on the Eagle. Pressing the V/M one
time will switch into memory mode. MEM
with a number will appear on the front panel
screen. Rotating the MULTI knob will
address memory locations that hold receive
and transmit frequency pairs to control the
transceiver. Turning the MULTI control
shows the number (1 –100) for the next
available or empty location. At this point, the
operator may either (A) copy the information
from both VFO’s to a memory location; or
(B) copy the memory information to the
VFO’s. To copy the memory channel back
into VFO mode press the FNC function
button then press the V/M button. Exit
Secondary Function Mode by pressing FNC.
Your favorite memory can now be tuned and
modified with the VFO.
Storing a Frequency to Memory (6)
When the main display holds a frequency you
wish to store into memory, Enter Secondary
Function Mode then press V/M. The MEM
front display will show the number of the last
used storage location (1-100). You may
either accept this location by again pressing
the V/M button or change the location by
rotating the MULTI knob first. An unused
location displays a series of dashed lines --.---

Headphones (1)
Headphones using a ¼” mono or stereo
connector can be plugged into the jack #1
located on the front of the Eagle. Headphone
Impedance from 8-32 ohms will offer
adequate audio levels.
Mode (23)
Pressing the MOD button will toggle the
modes to your desired choice. The Eagle will
change modes each time the button is pushed.
The desired mode is displayed in the top right
hand corner of the Eagle screen. The Mode
setting utilized in a given band will be
recalled when that band is used again.
Monitor (20)
When the Eagle is in a voice mode you can
monitor the transmitted audio signal.
To adjust the monitor on or off or level:
1. Enter Secondary Function Mode
2. Place the Eagle in transmit by pressing
the microphone PTT button.
3. Toggle the Monitor Function on and off
by pressing the BAN button.
4. You can now adjust the monitor level
with the MULTI knob.
The monitor will also work in tandem with
the AF gain control giving proper audio out
of the speaker. Note: there will be no
indication of the monitor being turned on or
off on the front screen. The effect of the
Speech Processor can be heard when Monitor
is on.
PBT (32)
Verify that the PBT control is at the top dead
center of rotation to begin listening in all
modes.
The PBT control will allow you to move the
passband back and forth across the desired
signal. It is beneficial in dropping QRM out
of one side or the other of the passband or it
can simply be used to improve the quality and
intelligibility of the signal. An excellent
experiment for digital communications is to
work the PBT control along with the BW
bandwidth control for the greatest selectivity
and interfering signal rejection.
BW (31)
Adjusting the BW control will allow you to
select the DSP filtering of your choice.
Larger numbers increase the band width and
smaller numbers will decrease the band
width. This control increases the selectivity
and removes close in unwanted signals. This
control will automatically select the correct
roofing filter ahead of the DSP filtering
provided a specific roofing filter is installed.
Fast (19)
To change Tuning Rate press the FAST
button to toggle between 1 Hz, 10 Hz, 100
Hz, 1kHz, 10 kHz Tuning Rates. Each press
of this button will step to the next Tuning
Rate and you will see this represented on
VFO A. Tuning Rate is recalled per mode.

AF Gain Control (4)
Note: this is a dual concentric knob. The
inside knob controls the audio volume level
to the speaker or headphones. Turning the AF
control completely counter clockwise
removes power from the Eagle.
RF Gain Control (5)
The outer ring on this control increases or
decreases the receiver IF gain. It is a general
rule on the more modern DSP transceivers
such as the Eagle to adjust the RF gain fully
clockwise and then slowly back down the
control (counter clock wise) until you reach a
convenient signal to noise ratio. You will
discover this control will vary from band to
band. As you lower the RF gain it may be
necessary to increase the AF gain to get a
comfortable listening level.
AGC (14)
Eagle allows for 3 convenient AGC setting
FAST –MEDIUM –SLOW. For most
sideband operation a slow AGC is usually
preferred. The letters F –M or S will appear
on the screen when you toggle to your
favorite setting. To change the AGC setting,
first Enter Secondary Function Mode, then
press the LOCK/AGC button until desired
setting appears. Exit by pressing FNC.
The AGC setting utilized in a given mode
will be recalled when that mode is used again.
NR (9)
To activate the DSP noise reduction just press
the NR button to turn this feature on and off.
When turned on, NR will appear on the front
screen. NR always defaults to OFF when
power is reapplied to the Eagle. Press and
hold NR to bring on screen the settings from
1-10. The multi knob will allow you to adjust
the noise reduction value for your comfort
level. Press NR again to exit the adjustment
mode. The noise reduction system used in
the Eagle is a wonderful tool that can assist
you in hearing weak signals under noisy band
conditions. Under some conditions the NR
may affect the quality of a received signal
when certain noise and band conditions are
present. Often times experimenting with this
tool under varied signal strength and band
noise such as atmospheric noise will make for
a more pleasurable listening experience.
Most of the time you will discover that DSP
noise reduction will not be necessary
especially with strong incoming signals.
PRE (16)
The preamplifier in the Eagle is designed to
give you a 12dB increase in signal strength.
It is best suited for weak signal reception. To
activate the receiver preamp, first Enter
Secondary Function Mode, then press the
PRE/ATTN button to activate or deactivate
the preamplifier. Exit by pressing FNC.
When the PreAmp is on, PRE is shown on the
display.

2.2. SSB Mode Operation
To begin SSB operation toggle the MOD
button to either the LSB or USB for the band
of choice you wish to operate.
Note: Remember to set the PBT (32) control
to the center of rotation so the side band
signal is centered in the desired filter. This
results in a starting point for proper side band
audio.
AN (8)
The AUTOMATIC notch is a useful SSB
feature and defaulted to off. This filter
implements a special digital algorithm in the
DSP system. There is no frequency
adjustment for the AUTO-NOTCH feature.
This filter will seek out and null all constant
carriers in the receiver passband. Once AN is
activated it may take a second or two for the
unwanted carrier to be notched away.
Remember some slight audio distortion may
exist as this DSP filter is being used to
remove an unwanted carrier. To activate AN
Enter Secondary Function Mode, then press
the NR/AN button to turn AN on or off. Exit
Secondary Function Mode by pressing FNC.

Chassis ground and mic signal ground are
separated to reduce the possibility of
introducing stray hum or RFI into transmit
audio signal. We recommend that the case of
the microphone also be tied to chassis ground
on the transceiver via a shielded cable to pin
5. This is to help assure stray RF does not
have a path to be coupled into transmit audio.
The cable carrying mic signal and mic signal
ground should be shielded. This prevents the
cable itself from acting as an antenna and
coupling RF back into mic audio. NOTE:
Some aftermarket microphones are not wired
with separate microphone signal grounds and
chassis ground. We recommend separate pins
for use for mic negative signal and chassis
ground as shown in Figure 2.2-2
MIC (11)
To adjust the microphone gain simply press
the MIC button on the Eagle and view the
letters MIC on the front display with numbers
to the right. At this time key and speak into
the microphone to adjust the MIC gain. Use
the MULTI knob until the ALC light begins
to flash on voice peaks. Your Eagle is now
transmitting with proper ALC levels for
undistorted SSB operation. Ten-Tec has set
the hardware microphone level to
accommodate the standard hand microphone.
If other microphones are used with the Eagle,
which may need more gain, Ten-Tec has
provided a hardware microphone gain
control, See Figure 2.2-3. Setting the
microphone gain around 35-50 and then
adjusting the trim pot on the left side of the
transceiver until proper ALC is accomplished
will help make the Eagle flexible with a
multiple of different style microphones.

BW Settings (31)
Normally below 1800 Hz filtering greatly
diminishes the intelligibility of the side band
audio. Above 1800 Hz will increase band
width for increased audio fidelity.
The bandwidth control performs 2 functions.
1. It will increase or decrease the DSP
filtering independent of any mode.
2. It will select the proper roofing filter
based on the DSP filter.
PBT Settings (32)
Rotating the PBT control during heavy QRM
plus adjusting the filter Bandwidth setting
will greatly reduce close in interference.
Some practice may be necessary to determine
the most comfortable bandwidth and PBT
setting when in crowded band conditions.
