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. Endless Potential for Teaching Young Hams the Trade

    Posted by Horace Hamby on 2nd Mar 2015

    The 506 Rebel exceeds expectations, as supplied, with the ease to get it on the air. It puts Technicians on their HF band and mode (40m CW); and on the path to General. Maybe it easier to operate than most Handhelds on VHF and UHF. Fun! Right out of the with specially packed box; excellent training Videos. Easy to operate.
    Now to define some exciting learning experiments with measurements where youth can experience Radio elements and programing. It adds another path showing the exciting experience of learning science in Amateur Radio. I can hardly wait to try a series of Antenna setups with local nets!!! Horace N7DRW

  2. Fun Rig

    Posted by Hank - W4JT on 25th Dec 2014

    This is a nice way to get back into the learning side of ham radio along with some fun QRP operating.

  3. Can't wait to play with it...

    Posted by Unknown on 25th Nov 2014

    It is a Christmas present, but I did check out the Rx and Xmt just to make sure they work. The receiver sounds great and I am anxious to start experimenting with it! Lots of possibilities here.

  4. A fun rig

    Posted by Howard on 23rd Jun 2014

    The Rebel is easy to use out-of-the-box. Once you get the hang of modifying and uploading software codes, it is easy to customize as well. My only gripe is that a very basic overview of how to acquire, modify and upload the codes would have been helpful. The info is on the web, but it's very fragmented and often in a form that is not user-friendly for the beginner. I see on the Yahoo group that some buyers have given up because of that. I have uploaded a very brief description for beginners (I am one) onto the Rebel Yahoo group files.

  5. Real ham radio

    Posted by Michael on 5th May 2014

    Easy to buy on line. We'll packed and works well out of the box.
    It's a rig that is built for you to change into the rig you want.
    You are not going to get lots of features you will never use.
    If it lacks something you need there is probably software to instal.
    At last a black box made to be customised.

  6. Great Concept

    Posted by David KV4VE on 30th Apr 2014

    I just received this radio about a week ago. As a total newby to the Arduino type controllers I was hesitant to take the cover off and start trying the RebellAlliance mods. Well, after a few days of off and on reading and testing,(read: beating my head against the wall:) ) I was able to get the rig up and running with all the mods except the "Bandswitch". (Which I don't have all the parts for yet)
    The radio itself is of excellent quality. Well made and with a very good receiver. I've been so wrapped up in learning how to modify it, that I haven't gotten around to having an actual QSO with it! My goal for this little QRPer is to use it on the back deck this summer. Can't wait!!!

  7. Great QRP Radio

    Posted by Jeff on 31st Mar 2014

    Looking for a small, QRP rig that has flexibility for future options via the ability to upload new firmware. Radio works very well. First evening I hooked it up to my 20m Inverted V and within a couple minutes got a contact from another QRP operator using a K3 1200 miles away. Great signal and easy to operate. Looking forward to adding an LCD display.

  8. TenTec Rebel is a great QRP radio, and Learning Platform

    Posted by Rick Beatty - W7RNB on 27th Dec 2013

    I got my REBEL for recently and have become hooked on its simplicity of use and as a software learning tool. You don't have to write software, because it is simple to use right out of the box. 10 minutes and your on the air. For those who are curious about what is behind the VFO knob here is your chance to see. Here is hope that TenTec will consider an all mode, all band radio in the future that is configurable like the REBEl, BRAVO TENTEC!
    Summary ? Excellent radio project for QRP, 5 watts output, east to use, fun to play under the hood, software configurable, open source software for learning and adding your option.


  9. Great basic qrp transceiver with dds vfo

    Posted by W5san on 18th Dec 2013

    Very nice product. I have lots of nice expensive radios (ts-590s, kx3, etc) and i like to use them, but would never modify or tinker with them. I have been building some simple sa612 based dc receivers and ran across some Arduino based dds vfos. This rig was a logical next step for me.
    I hooked up a 1602 lcd and modified the base software to display frequency, signal strength, battery voltage, and rit offset similar to the H1B1 display and am very pleased with its performance so far.
    The hardware is set up for the basic lcd and was hoping that the base software would already display frequency at least, but it didnt. Would be all some hams would want - a dds stable vfo, full coverage 40 and 20 (including ssb), superhet receiver with adjustable if crystal filter. (add simple lcd)
    I am not a big Yahoo fan, so i would have preferred a cd with base software and some helpful startup tips. I think the inovative qrp world will embrace this rig and do many enhancements

  10. The 21st Cnetury parts box

    Posted by Richard K5ANR/QRP on 28th Nov 2013

    This reminds me so much of ordering a set of parts from somewhere and then doing mods on the kit except this is mostly in software. yes, something new but there is nothing wrong with learning -- especially if you can remember what you learned!
