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. 539 / Argonaut VI Users manual Part #74479 Printed in USA 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, 539 / Argonaut VI Users manual Part #74479 Printed in USA Release 0.10 – November 13, 2012 160M - 1.795-2.005 80M - 3.495-4.005 40M - 6.995-7.305 30M - 10.095-10.155 20M - 13.995-14.355 17M - 18.063-18.173 15M - 20.995-21.455 10M - 27.995-29.705 7 8 Argonaut VI 9 10 Figure 2-1 539 Front Panel- (with indexes) 2. Easy Operation Guide 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. 9 10 30 Figure 2.1-1 Meter-Signal Strength 2. SWR-Meter, while transmitting and the MOD button is pressed, the meter shows the SWR as calculated on the bridge in the Argonaut VI. 9 10 30 1 1.5 2 2.5 3 HIGH Figure 2.1-2 Meter-VSWR 539 / Argonaut VI Users manual Part #74479 Printed in USA Release 0.10 – November 13, 2012 7 8 Argonaut VI 9 10 Figure 2-1 539 Front Panel- (with indexes) 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. 539 / Argonaut VI Users manual Part #74479 Printed in USA Release 0.10 – November 13, 2012 7 8 Argonaut VI 9 10 Figure 2-1 539 Front Panel- (with indexes) 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. 539 / Argonaut VI Users manual Part #74479 Printed in USA Release 0.10 – November 13, 2012 7 8 Argonaut VI 9 10 Figure 2-1 539 Front Panel- (with indexes) 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. 539 / Argonaut VI Users manual Part #74479 Printed in USA Split (8) To operate SPLIT mode be sure TMB switch is in the Top position. Press SPL (PRE) button. The word SPLIT will appear between VFO A and VFO B. VFO B will show the transmitted frequency in smaller font. To exit SPLIT mode, press the SPL (PRE) button one more time turning off the word SPLIT. AGC (9) Be sure TMB switch is in the Top position. Press AGC (NR) button will toggle the AGC between fast, medium, and slow. The letter F, M, or S will appear below the last digit on VFO A A/B (10) Be sure TMB switch is in the Top position. When you press and hold the A/B (MOD) button you will now be able to set B VFO to equal VFO A. A quick press of the A/B (MOD) button will reverse both A and B VFO.

The Argonaut VI features the common 8-pin microphone jack used in many amateur radio transceivers. Most dynamic or Electret Microphones can be used. When adapting a microphone, please refer to the wiring diagrams in Figures 2.4-1 and 2.4-2 Figure 2.4-1 Transceiver Microphone Jack Front View Figure 2.4-2 Transceiver Microphone Jack 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.

Windows audio controls will also need to be set within the specific programs you will be using. This is usually found under the SETTINGS on your digital mode programs. A proper audio level occurs just as the ALC light flashes slightly when in transmit. If the ALC light is on continuously you probably have too much audio into the Argonaut VI. Release 0.10 – November 13, 2012 17 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. 539 / Argonaut VI Users manual Part #74479 Printed in USA Release 0.10 – November 13, 2012 18 2.9.

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. Release 0.10 – November 13, 2012 20 2.10.

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. 539 / Argonaut VI Users manual Part #74479 Printed in USA Release 0.10 – November 13, 2012 22 FUSE 7.5A AUX 11 ANT – TEN-TEC, INC.

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 Part #74479 Printed in USA 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. Release 0.10 – November 13, 2012 31 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 539 / Argonaut VI Users manual Part #74479 Printed in USA Release 0.10 – November 13, 2012 32 7.
