Rebel Model 506 Open Source QRP CW Transceiver

2.00 LBS
Calculated at checkout


The TEN-TEC Rebel model 506 transceiver is designed with the purpose of providing Ham Radio operators a platform for developing and writing code using the open-source Arduino programming environment. It is a factory built CW QRP radio with a Chip Kit Uno 32 Arduino compatible processing unit that holds the operating program. The radio is provided with programming for basic operating functions that allow it to be used immediately as a basic QRP transceiver. Additional operating functions can be programmed by the user, either by writing the code or copying/adapting code developed by members of a growing  number of Arduino special interest groups. It is this sharing of programming routines and ideas for functionality that is the heart of the Arduino open-source concept. 

Basic features include a 40 & 20 meter QRP transceiver with internal jumpers to change bands.  Full band coverage on both bands.  Typical power output will run 4-5 watts with 13.5 VDC.  A drift free operation is achieved through DDS synthesizer technology.  CW sidetone through headphones. Three filter bandwidth choices and three tuning rate adjustments included with the stock program.

  1. Learning Opportunity!

    Posted by Lynn Hagar on 17th Oct 2013

    Thanks for creating an educational ham radio product!

    By viewing the Ten-Tec Rebel 506 play list on YouTube channel NG9D, all radio amateurs can see and hear this little gem of a QRP transceiver:


    I will report my learning experiences with periodic updates to that link.


  2. a truly unique and wonderful radio

    Posted by Tom on 23rd Sep 2013

    If you are a ham interested in learning arduino, or someone who tinkers with software and wants to learn about ham radio, you will not be disappointed with this radio. The yahoo group is a great resource, with development already underway for adding features like a built-in keyer, frequency display and band switching. Note that this is not an SDR (software-defined radio) but adds another aspect of using software to customize your radio. Also note that the chipkit board used in this radio is not exactly the same as an arduino board, but it is more powerful, and is (mostly) compatible with the arduino. This is an innovative and educational radio - thanks ten-tec!

  3. Exciting

    Posted by Chas W3KC on 19th Sep 2013

    I am very pleased with this little 5 watt rig.
    It's pretty basic as shipped but very usable with nice filters, RIT, and QSK.
    In the week I've had it, I have made plenty of contacts - and even some European DX on 40.
    Keeping track of the QRG is a bit cumbersome but do-able. The red dot blinker in the TenTec logo is a really nice touch though.
    My first addition will be a digital readout, and that's the exciting part - there is lots of potential for enhancments.
    I've ordered the ARRL Arduino / PICAXE projects book to get some insight into the technology.
    Thanks to TenTec for opening the door via open source with the modestly priced but high quality Rebel.

  4. Was not what I expected - but for the right person...

    Posted by James T. "Jim" Rogers on 17th Sep 2013

    I read too much into the "Open Source" description and thought I was ordering a small SDR. When I found it to be an analogue radio controlled by a micro-controller, that was something I have a great deal of experience with and therefore its utility, in my case, disappeared. But, for the right person, someone who wishes to explore micro-controllers in the amateur environment, and enjoys QRP, not a bad deal.
