About the Open QRP TransceiverI am excited to have the opportunity to carry on for K1EL's terrific OpenQRP transceiver kit. This has been in development over the past few years and I was a beta builder as well having built several versions. This is a solid transceiver and has many bells and whistles including:
Supporting FilesAssembly Manual
Parts By Section
Bill of material/Inventory
As of May 25th we are sold out. Please note that Kanga Products UK is also kitting this transceiver in the UK.

Background from K1ELOver the past couple of years I have been fascinated by the Open Source software revolution. There are countless examples of how the open sourcing of software has fostered the development of exceptionally good free software applications. I would like to present an experiment to see if it’s possible to develop ham radio equipment by a community of radio amateurs who exchange ideas on the Internet.
I will kickstart the idea by presenting a microprocessor controlled QRP transceiver design and open the design up in a form that anyone can download, modify, and improve. It is expected that if you participate that you will, in return, share your ideas and work with others on the group. This website will provide a forum for this purpose as well as a means to upload your design files.
One astounding result of open sourcing is the appearance of free hardware and software design tools that are of exceptional quality. All the design work for the openQRP transceiver has been done on tools that can be downloaded and used with no cost or restrictions.
The software design used in the transceiver will be covered under an open source license that applies specifically to software.
The hardware designs presented here share the principles of free and open-source software. All of us can learn from each other by sharing concepts and ideas. To make this happen I have released original design files in open formats. These files are licensed under a Creative Commons Attribution Share-Alike license, which allows for both personal and commercial derivative works, as long as they credit openQRP and release their designs under the same license. It is important to note that the Arduino CPU design, incorporated in the openQRP transceiver, is covered by Arduino’s own license.
As I mentioned above, my plan is to present a transceiver design and document the development and debug. As I write this I am in the middle of debugging it and I will present all the details (both good and bad) in the Blog section of this site (Project Progress). I think there is just as much learned by studying mistakes as there is by studying success. When it’s complete I will offer blank PC boards and parts kits at a minimal cost. Of course you can build your own copy any way you would like, that’s part of the deal.
A word about firmware. (I like to refer to software that controls a piece of hardware as firmware). The firmware that controls the transceiver runs on an Atmel microprocessor. I use Arduino as the firmware development platform. I quote from their website: “Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software” I support ‘on board microcontroller programming’ on the transceiver PCB so that anyone can write software for it and then download it into the board. The source for the basic transceiver control firmware will be available for free download just like the PCB design files.
The final radio package is close to completion, I am in the final stages of documentation now. The development of the radio is covered in the “Project Progress” Blog. To view, click on the Project Progress tab and browse back through installments that go back well over a year.
