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.

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.

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.

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.

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!!!

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.

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.

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

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!

I just received my Rebel today from Ten Tec. After getting it unboxed, I
connected it to a Power Supply, a dipole antenna, my EZKeyer (AA0ZZ), some headphones and started tuning around on 20 Meters. The band was hopping here in FL and the Rebel receiver seemed very "hot". After acquainting myself with the BW and Tuning controls, I decided to take the plunge and put out a CQ on14.060. Much to my surprise, I got a call from Jorge, EA2LU in Spain. He gave me a 549 and we had a very nice chat.
This is a neat little rig and now I see why everyone on the Yahoo Rebel 506 group is so enthusiastic about it. I'm very interested in getting a display and a keyer in it and since I don't know the first thing about Arduino programming, I will be actively following the work being done by the talented hams on this Group. This is a great Yahoo Group and I look forward to getting my hands dirty with my new Ten Tec 506.

I took the radio out of the shipping container, connected it up to power, antenna, key, speaker and an LDG autotuner and got on the air for the Nov 2 ARRL Sweepstakes contest. Some serious problems that need to be addressed are lack of display and switching bands.. In order to log a QSO, I need to know what frequency I'm on. The best I could do was guesstimate. I think if I roll the turning knob over until the red LED comes on, that would be the lower band limit and then I can guess where the digital folks come on with the RTTY or PSK warbling so that would be 14.070 or 7.070 respectively. Divide the difference by the number of full rotations and yes... I can get an estimate of what frequency I'm on. Most definitely need a display or a CAT interface to know exactly where I am. Also, taking the case off to change bands. I changed between the 20m and 40m about 10 times per day; trying to pick up grayline contacts. I wound up with just leaving that pretty case in the off position. I am very excited about the radio. Pretty good receiver and a few filters that helped a lot. I was able to discern weak signals in large 20m pileups. Overall, I'm very impressed with my first use. Never made any contacts though... from Alaska, a qrp signal is even smaller than normal. Based upon my first time use, I give this radio a 5 star and thumbs up rating. What an incredible experimental platform. Good job Ten-Tec.
