1.4. Connection to Antenna &
Power Supply
The Argonaut VI 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 will be
needed. Any antenna to be used with the
Argonaut VI must, ultimately, be fed with 50
Ohm coaxial cable.
The Argonaut VI transceiver requires a
source of well-filtered and regulated DC
voltage. The supply voltage for the Argonaut
VI is 13.8 Vdc nominal +/- 15% to allow for
mobile and battery operation. The voltage
source must be capable of supplying 5-7
amperes continuous duty. We recommend
using the included DC power cable (P/N
86095).
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
Argonaut VI. 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
Argonaut VI, 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.
Release 0.10 – November 13, 2012
1.6. Philosophy of design
With the Model 539 Argonaut VI, Ten-Tec
has created a QRP transceiver combining
simplified controls and ease of operation with
the excellent performance of a low first IF
ham-band architecture in a compact, mobilefriendly structure. The analog portion of the
radio is double conversion with IF
frequencies of 9.0018 MHz and 22.5 kHz. A
third conversion to zero-frequency IF is
accomplished in the DSP processor.
Refer to the Block Diagram in the
“Specifications” section for the following
discussion. Receive signals are routed to a
T/R switch 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
9.0018 MHz and routed to one of the three
roofing filters. After selectivity roofing, IF
amplification is provided by a variable gain
amplifier which also develops the high-level
AGC. Finally, the 9.0018 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 Oscillator board generates first
and second LO's with a DDS circuit 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.
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 to the
antenna.
The Argonaut VI is designed to cover the
following hambands:
The PIC processor in the front panel CPU
module executes firmware stored in
EEPROM to perform housekeeping functions
such as synthesizer programming/tuning,

2.1. Front Panel Indicators
TX/ALC LED
The “o” in the ToT Logo includes an LED.
The primary purpose for this LED is to
identify when the Argonaut VI is transmitting
approximately 80% or more of the selected
power setting. For CW mode, this should be
active during the entire dit or dah transmit
cycle. For Voice modes this will be when
transmit voice is 80% or greater than the
selected power level. This LED is also used in
the firmware update mode.
When in transmit the bar graph meter will
display your power output peaks. When you
wish to view the SWR, ensure that the three
position switch (5) labeled with TMB is in the
middle (M) position, and press the MOD
button while you transmit. The meter will
now display your SWR while the MOD
button is pressed. When the MOD button is
released the SWR graph disappears and the
power output will be displayed.
It is recommended that the rig be held in
transmit continuously prior to pressing MOD
to view the SWR. It is not advisable to try to
view the SWR when sending a stream of CW.
S-Meter / SWR Meter
The meter on the Argonaut VI offers two
functions:
1. S-Meter, in receive mode, the meter
shows the signal strength.

2.2. Front Panel Controls
This section provides a very brief overview of
the front panel of the Argonaut VI, more
details on each control is given later in this
manual.
Two Dual Concentric POTS (1, 2, 3, 4)
The Argonaut VI front panel provides two
dual concentric multi -function pots. One for
AF/RF Controls, and the other for BW/PBT
controls. Using the AF knob, rotating the
knob fully counter clockwise removes power
from the Argonaut VI. Rotating the AF knob
clockwise will apply power to the Argonaut
VI and increase AF Levels. Using the BW
knob, rotating fully counter clockwise enables
the adjustment of further mode dependent
features. More on this later in the manual.
Rotating the BW knob clockwise will
increase or widen the selected DSP
Bandwidth.
Multi Function Buttons (7, 8, 9, 10)
There are four buttons on the front panel to
change different operational features within
the Argonaut VI. These buttons perform
multiple functions. The Primary Function for
the buttons on the Argonaut VI is screened
directly on the button. Notice the four
buttons have text printed above the button, on
the button, and below the button. The location
of the TMB switch identifies the function as
stated by the T(op) row of text above the
button, or the M(iddle) row of text printed on
the button, or the B(ottom) row of text printed
below the button. These buttons also take on a
fourth meaning when the BW pot is adjusted
fully counter clockwise and the switch clicks
to the (CW) position. The functionality is
described in the following sections.
Three Position Switch TMB (5)
There is a three position switch on the front
panel with text T, M, and B next to it. These
refer to the position of the switch T(op),
M(iddle), and B(ottom), which identifies
which function the four multi function
buttons will perform.
Main Encoder for various adjustments (6)
There is a single Main Encoder on the front
panel that is used primarily for adjusting the
tuned frequency. It also serves as the
adjustment on various other features.

2.3. General Operations
RF Gain Control (2)
This section of your Argonaut VI Manual will
discuss the button operation and adjustments
common to all modes on the Argonaut VI. It
is important to read this general operations
section prior to operating the Argonaut VI
because the BW Pot (3) and the state of the
“TMB” three position switch (5) change the
function of the four push buttons (7, 8, 9, 10).
AF Gain Control And Power Switch (1)
The inner knob (1) of the AF/RF knob
provides two functions: Power control for the
rig and the AF Gain control.
Power Switch (1)
To turn on the Argonaut VI, rotate the AF
Gain control (1) clockwise. The LCD screen
will display the current firmware version and
unit serial number for three seconds. The
LCD screen will then display the last band,
frequency, and mode used. To turn off the
Argonaut VI, rotate the AF Gain control (1)
counter clockwise until power is removed and
the LCD display turns off. To place the
Argonaut VI in any of the special power up
modes, see the section on “Power Up
Modes“ for more information.
The outer ring (2) of the AF/RF knob
provides the RF Gain feature. Adjusting the
outer ring RF Gain control clockwise
increases RF Gain action up to 100% at the
full clockwise rotation. Adjusting the outer
ring RF Gain control counter clockwise
decreases RF Gain action down to 0% at the
full counter clockwise rotation. Depending on
signal strength you may find a more pleasing
signal to noise ratio by turning the RF gain
control down to a comfortable listening level.
AF/RF Gain Control Usage Tips
One way to make a noisy band easier to listen
to and pull out weaker signals is to decrease
the RF Gain to the point where the audio is
difficult to hear, then increase the AF Gain.
Balancing these two controls in a TenTec
transceiver helps one pull out signals, and
helps decrease the band background noise to a
level that is much more enjoyable and reduces
contest fatigue.
AF Gain Control (1)
This control adjusts the volume of the internal
speaker, and also for the headphones if one is
plugged into the rear jack. Rotating the AF
Gain control clockwise will increase the
volume to a maximum of 100% at full
clockwise rotation.

BW (3) Bandwidths
Band (7)
Adjusting the BW control will allow you to
select the DSP filtering of your choice. This
will increase the selectivity of receive and
helps remove close in unwanted signals.
Be sure TMB switch is in Middle position. To
change bands or toggle through the Ham
bands press the BAN button and the next
Ham band will be recalled. BAN will only
toggle through the Ham bands in one
direction. 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.
The range of the DSP filters is 100hz to
2500hz in 25hz increments. When the
optional 6kHz filter is installed, this permits
4k, 5k, and 6k DSP bandwidth selections.
When dealing with crowded band conditions
and close in adjoining signals one will find
this control very useful as you begin to
narrow the filter to eliminate 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.
PBT (4) Pass Band Tuning
Verify that the PBT control is at 12 0'clock 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.

Recommended Cable Wiring
Pin 2 (+9 Vdc) need only be connected if the
microphone element in use is an electret
condenser requiring a polarizing voltage.
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

2.8. Interfacing to a computer
for Firmware Update
Mode and PC
Control/Logging Purposes
The software interface for the Argonaut VI
utilizes standard Windows driver supplied
with Windows versions XP through Windows
7. An installation program is available for
download at the TenTec download webpage
for
the
Argonaut
VI.
Start
at
www.tentec.com, and follow the links until
you get to the Argonaut VI’s Download page.
Look for the latest instructions entitled “USB
to UART driver Installation….”. Download
and follow the instructions.
NOTE: when you plug the USB cable into a
different USB port on the PC, it will most
likely get a new COMx port number defined.
Be aware of this when reconnecting the USB
cable to the computer so that you can set it
properly in the computer program that you are
using to communicate with the Argonaut VI.
If at any time you need to see what “port” the
Argonaut VI is connected to, go back into
Device Manager, expand the “Ports (COM &
LPT)” selection, and you should see “USB to
UART (COMx)”. Note the x in the COMx
that is reported by Device Manager. You will
use this number when running Logging or
Control programs, the Flash Update Utility,
etc.
If required, you can change the actual port
number being used to a lower number if
required. Sometimes the update program on
some computers will require a port number
lower than 10. To do so, double click the
USB to UART (COMx) text, go to port
settings, select advanced, and select a
different COM Port Number from the pull
down box. It may display a warning message,
if it does, confirm/ok the change. Click
OK/Confirm/etc. until all windows are closed.
Disconnect the Argonaut VI, wait a few
seconds, reconnect the Argonaut VI, and you
should see the new port number in Device
Manager.

Firmware Update Mode (A/B (10))
To upgrade your transceiver, visit the TenTec
web site (www.tentec.com) and download the
installer for the latest firmware version. A
link will be available on the 539 Downloads
page. This link will be titled with the
available version number of the firmware.
Example: “Firmware Version 1.585”. The
Date of the file will also be shown.
Here is the sequence of steps to follow once
the .exe file has been downloaded from the
Downloads web page for the Argonaut
VI/539.
1) Turn Transceiver OFF.
2) Turn Transceiver ON to verify that the
Argonaut VI has appropriate power. E.g.
the Argonaut VIs front panel display
shows the normal indicators and
frequencies.
3) Turn Transceiver back OFF.
4) Connect a PC to the transceiver using a
standard USB cable. (Note: if already
connected, disconnect for a second or
two, then reconnect, helps computers that
don’t “disconnect” the USB driver unless
it is physically disconnected)
5) Be sure the TMB button is on Top. Turn
the Transceiver ON while holding down
the “A/B” (MOD) button.
When the Argonaut VI starts up in flash
update mode, you will see the TX/ALC LED
flash on for a second, then back off, then back
on for a second. IF the USB Cable is
connected and the drivers are working
properly in the PC, then the TX/ALC LED
will turn back off. If the TX/ALC LED
remains lit and does not shut back off, then
check your USB cable and ensure that the
drivers are installed before proceeding.
6) Start the Update program
7) Select the COM port to which the
Transceiver is attached.
8) Choose UPDATE under the PROCESS
menu.
539 / Argonaut VI Users manual
Part #74479
Printed in USA
9) Select the RUF file under the Process
Menu.
10) The program will update the radio and
report any errors encountered.
During the update process the TX/ALC LED
will flicker showing active communications.
The update program will confirm that lines
are getting sent/programmed.
11) When finished, the 539 Argonaut VI will
restart and run the new firmware.
12) Sometimes Windows doesn't like the
transition of the radio from firmware
update mode to radio mode, so it is
suggested that once the radio is back up
and running showing the tuned frequency,
turn the rig back off, wait a few seconds,
then turn it back on. This helps Windows
find the USB / COM port easier.

2.11. Extended Feature
Access via USB/Serial
There are more features available for the
Argonaut VI that are not accessible via the
front panel controls. For this purpose, the
USR button, MR button, and MW button are
able to be programmed with new
functionality using a PC.
The USB interface also permits changing
various settings that cannot be mapped to
front panel control buttons.
This includes features such as VOX, AN, etc.
2.12. Retaining User Settings
The Argonaut VI operates the same as most
modern TenTec rigs do with regards to the
ability to retain user settings through a power
reset. For various reasons, user settings are
not immediately written into the non-volatile
memory every time that the user changes a
setting. When a user setting is changed, this
value will be stored 15 seconds after the user
has made his last change to any user setting.
Example:
Change Main Frequency to 14.02 (This starts
the 15 second user value store timer)
2 seconds later change Mode to CW (This
resets the user value store timer back to 15)
5 seconds later change AGC to Slow (This
resets the user value store timer back to 15)
Finally, do nothing for 15 seconds, and all of
the above values will be stored.
If changes are made, and the unit is turned off
before the 15-second timer has expired, then
all of those changes made since the last store
point will be lost.

Keying a Linear Amplifier
Pin 8 on ACC-1 will provide an open
collector output for keying a linear amplifier.
The Argonaut VI 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
Argonaut VI must use an amplifier interface
relay such as the model 318 sold through the
Ten-Tec company. When using the Ten-Tec
model 418 solid state linear (sold separately)
the proper interface cable is provided with the
amplifier for both keying and band changing

4.2. Using the 712
USB/Soundcard Interface
To use the 712 soundcard interface for digital
modes, connect the 712 device between the
ACC-1 connector and the USB port on your
Windows computer. Audio generated from
your favorite digital programs can be used
with the Argonaut VI. See the section
“Digital Mode Operation” for directions on
how to set up the the line input for digital
mode operation.
The 712 USB Soundcard Interface should
only be connected to the Argonaut VI when
the setup is intended to be used for Digital
modes via the PC. Remember, the USB
Soundcard, when plugged in, becomes the
sound card that all windows sounds and video
sounds will go through. Meaning, when the
712 detects audio from the PC, e.g. a
Windows DING, it will put the Argonaut VI
into transmit.

6. In Case of Difficulty
While we cannot cover every possible
problem, here are some hints for dealing with
some potential difficulties.
Check the
obvious. Is your dc power source okay?
Check power supply, cable and connector(s).
Is the 25 ampere fuse loose or missing?
Antenna problems? Try a dummy load. Is a
proper antenna connected?
Is any
external antenna switch connected and
properly set? Have you double-checked the
Argonaut VI’s many control settings,
including those in the Configuration menu,
for your intended mode of operation? Have
you checked how the optional Filter’s are
installed and confirmed their installation
order within the Configuration Menu?
One problem that results in no audio or poor
audio is the fact that sometimes you make an
adjustment to a setting and subsequently
nothing seems to work properly anymore. The
method that resolves setting issues that you
just can’t find, is to perform a Master Reset.
This was discussed in the “General
Operations” section of this manual.
Problem: No Receive Audio
Is the AUDIO (AF) turned up?
Is RF GAIN turned down? Is squelch
activated? SQL will appear in block letters
on the screen. Press FNC then FAST/SQL
and check SQUELCH level.
Is the speaker wire internal to the rig broken
or disconnected? (Have you pulled the covers
off recently?) Try headphones to see if audio
returns.
Is NR off? Under some circumstances, noise
reduction can cover band noise completely,
leading the user to think no audio is coming
from the speaker.
539 / Argonaut VI Users manual

Problem: Distorted SSB transmit – or –
Perceived RFI in the shack.
Be certain the mic gain is set properly. The
ALC LED should flash on voice peaks, but
not remain continuously lit in SSB modes.
Check the setting of the speech processor. An
excessively high setting can reduce audio
quality.
A frequent cause of a distorted SSB signal is
inadequate RF grounding resulting in RF
feedback. Common RF grounding problems
are no ground connection, or too long a lead
to a good ground. Many problems relate to
the lack of an RF station ground, as
contrasted with a safety ground connection.
We recommend bonding all equipment
chassis together with short heavy metal braid
or strap. Make these connections from
chassis ground lug to chassis ground lug and
connect the last piece in the chain feeding the
antenna to a good earth ground. This lead
needs to be as short as possible. Lengths near
¼ wavelength on any band used can be
particularly troublesome when the far end is
connected to earth. It is very important that
the external power supply and the transceiver
and all equipment with grounding lugs are
properly grounded.
Another potential cause of distorted SSB
arises when the station is in the near field of
the antenna.
This is a problem many
apartment dwellers face.
Distorted SSB transmit can result from
chassis ground and signal ground from the
microphone being tied together to a common
connection. This is a common problem with
third-party microphones. Assure the chassis
ground and signal ground from the
microphone is separated.
RF can also be induced into the transceiver on
any unshielded wires.

Problem: Transceiver power shuts off
while transmitting
The Argonaut VI is equipped with a siliconcontrolled rectifier that opens if the PA
current draw exceeds an instantaneous power
of approximately 30 amps. This will shut off
power to the transceiver. Excessive current
draw can indicate a problem with excessive
SWR due to antenna or feedline problems.
Power to the radio can be restored by cycling
the power switch and off or the 13.8 Vdc
source on and off.
Manager. It is possible that the USB port was
used previously and for some reason
Windows has not released it for use. In this
instance, disconnect the USB cable at either
the computer end or the Argonaut VI end, exit
the program you are trying to use, wait a few
seconds, then reinstall the cable and then restart the program you were trying to use.
Problem: No transmit, receive OK.
Are you trying to transmit outside of the Ham
Band?
If the above do not solve your problem,
please consult with our service department
(865) 428-0364 or service@tentec.com
Is the gain setting correct for the microphone
input or ACC 1 jack as appropriate?
Is the POWER control turned all the way
down? Press PWR and check.
If no transmit in digital modes, are you sure a
PTT signal is being sent from your TNC or
computer to the appropriate jack on the
Argonaut VI?
Are the internal fans running at maximum? If
so, then this could indicate the Argonaut VI
has a final amplifier temperature of 70
degrees C or higher. In this condition, the
radio will stop transmitting until the final
amplifier temperature is back down to a
reasonable level.
Problem: Get a “PORT in use” when
trying to run logging or computer control
program or when trying to update the
firmware.
Have you confirmed the proper port number
in Device Manager? Remember that when
connecting the USB cable to the USB port on
the computer, every time you connect the
USB cable into a different USB port on the
computer, it will have a different COM port
number. You can verify this in Device
