The Ten-Tec Patriot: an open-source SSB/CW/Digital transceiver

507-Patriot-low-res

Today at the QRP ARCI conference, Four Days in May, Ten-Tec is showing off their latest open-source transceiver: the Model 507 Patriot.

Building on the concepts behind the Model 506 Rebel, released last year, the Patriot is open-source and firmly targeted at the makers and experimenters amongst the amateur radio crowd. Like the Rebel, the Patriot is spartan by design, leaving it to the maker to develop the transceiver’s character via crowd-sourcing.

The Patriot arrives as a fairly bare-bones 20/40 meter transceiver, but with all of the essential functions pre-loaded, including:

  • AF gain
  • RIT
  • Bandwidth selection
  • Tuning step selection
  • Band selection (20 or 40 meters)
  • Tuning knob/encoder
  • Mic Level
  • Line Level in/out
  • CW Speed

I’ve had the Patriot’s progenitor for about a week now, and have had it on the air a bit. But as this is a very early beta version, I can’t comment on much other than to say that audio reports have been quite good on SSB. I’ll dive into the digital modes after the Hamvention.

Of course, when I receive an actual production unit of the Patriot, I’ll give a more thorough overview.

In a nutshell?  I like this direction for Ten-Tec and am happy to see that they are growing a new line from the seed planted by the Rebel. By producing basic, open-source, and relatively affordable radios, Ten-Tec may actually be blazing a path to transceivers with benchmark performance and crowd-sourced firmware. I have no idea if Ten-Tec is contemplating this, but I’m sure many manufacturers are–it’s a great direction for any company.  Meanwhile, stay tuned for more on the Patriot!

    There is not any Ten Tec Patriot on tentec.com

  3. Matthew Williams says:

    Curious on the reasoning behind the recessed pots for things. Especially a keyer. Can you override all of them in software?

  4. Jim Beard - AE5ZZ says:

    any idea of the power setting on the Ten-Tec Patriot?

  5. Joe KB3PHL says:

    This may be a stupid question but this radio doesn’t have any readout so how do you know what frequency your on? Or is that something they’re going to add once they start selling later on?

  6. k4swl says:

    Hi, Joe,

    The Patriot (and Rebel) defaults to a frequency when you turn it on or move from one band to the other. You can change that default.

    The red LED indicator blinks every time you tune one step (there are three tuning steps you can chose). I also use an SDR spectrum display to read the frequency.

    You can certainly add a frequency display as well. Many have done this with the Rebel.

  7. Matthew Williams says:

    Joe – it’s actually by design. The open source nature of the rig means a lot of features you can do yourself. There’s a set of pin headers on the rig that you can connect to and program the radio software radio yourself to do what you want. So you can buy whatever type of display you want and program the rig to control it. So you could show the display frequency, keyer speed, voltage, maybe an S-meter, etc etc.

    You can see a mod someone did on the Rebel here, they added an LCD to it and display RX/TX frequency, S-meter, keyer speed and power.

    Congratulations to TenTec! The Arduino is an exciting, mature direction in computing, with a very large, very active world-wide user community of hardware and software developers. An example: the 32-bit Intel Galileo development board is pin-for-pin compatible with the Arduino’s latest board, the Uno 3. Read on…

    “The Intel® Galileo board is a microcontroller board based on the Intel® Quark SoC X1000 application processor, a 32-bit Intel® Pentium® brand system on a chip (SoC). It is the first board based on Intel® architecture designed to be hardware and software pin-compatible with shields designed for the Arduino Uno* R3.

    This platform provides the ease of Intel architecture development through support for the Microsoft Windows*, Mac OS*, and Linux* host operating systems. It also brings the simplicity of the Arduino integrated development environment (IDE) software.”

    So there is a solid growth path for both the underlying computational hardware platform as well as the RF platform. Again, brilliant, TenTec, just very brilliant.

  9. Ron Giuntini says:

    Interesting the Model number. The second Argonaut was a 509 – wasn’t the first one a 508?

  10. Bruce W Haupt says:

    What is the price for the patriot and will 2 to 4 line lcd’s for freq & location, as displayed on p.48 of the Aug QST in the Rebel review be available

  11. KE7LWW John says:

    I have pre-ordered the Patriot @ $400. The chipKit UNO32 MCU is a very interesting story of modularity and easily provides many display options, including Pmods:
    •16×2 character display
    •Parallel or serial data interface choice
    •Simple terminal like display interface
    •Measures 3.3″ x 2.3″
    •Ships with a 6″ 6-pin cable, a 6″ 2×6-pin to dual 6-pin cable, and appropriate headers

  12. Chris, K4RCH says:

    How can the Patriot be pre-ordered? What are the specs. such as power out and duty cycle? I’m assuming the same as the Rebel. I’m looking forward to using the Patriot as the basis for my portable digital station.

  13. Bud Roeske says:

    interested to know all

  14. Patrick Bowen says:

    It would seem that the Rebel and Patriot are targeting folks that want to get involved in OpenSource/Open Hardware, without actually having to build a radio from scratch and program it. I believe that the Rebel, at least, achieves that goal admirably. Unless I was really determined to have non-proprietary equipment, it would be very hard indeed for me to justify spending $400 on the Patriot when I could could get an FT-817 for just a few hundred more that would be head and shoulders above the Patriot in functionality.

  15. KE7LWW John says:

    As you point out, the Ten-Tec Patriot is not a soldering project. Rather, it represents a pathway for HAMs who want to learn about digital signal processing enebled through the leveraging of the very large Arduino UNO architecture.

  16. KE7LWW John says:

    In 1985 the Hewlett-Packard Company introduced it’s Precision Architecture with this observation: hardware is simply the software to which a given implementation is committed.

    If a radio has even one integrated circuit then that radio is ‘software defined’. Transceivers that utilize Digital Signal Processors are particularly complex ‘software defined radios’. Gaining access to DSP firmware code has been a long, hard struggle for the developer community.

    With the Rebel and now the Patriot, Ten-Tec has opened up the world of DSP programming. Both of these transceivers are built around the Digilent chipKIT Uno32™ Prototyping Platform, a super-set implementation of the Arduino UNO3 architecture. The chipKit Uno32, in turn, is built around a Microchip PIC32 microcontroller operating at 80 MHz. Ten-Tec utilizes the PIC32 microcontroller in other receivers and transceivers. http://opensource.org/ compliance is not trivial: I have studied the Ten-Tec Rebel documentation (https://www.tentec.com/pages/Transceiver-Downloads.html) and it seems more than complete.

    For me, the parallel in this arena to traditional HAM hardware: it’s like getting to make vacuum tubes and filters!

    I’m just waiting for it to be available for order.
