PortableSDR

Fully stand-alone HF (Shortwave) Software Defined Transceiver & Vector Network Analyzer. Designed for rugged portable use. Highly hackable.

 

DESCRIPTION

The PSDR is a completely stand-alone (no computer needed), compact, Portable Software Defined Transceiver (hence the name, sorta). Originally designed for backpacking use by Ham Radio operators. It includes complete coverage up to about 30Mhz (plus 144Mhz), it has a 168Mhz ARM processor, color display, and an innovative interface. 

Vector Network Analysis (which includes antenna analysis) and GPS functions are included. 

The entire design is Open Source. The electronics are designed and laid out to be easy to understand and tinker with. In addition to source code, schematics, board layout and parts lists, articles and videos describing the theory of the design are being created.

Source code and Design Files: All files (including the above diagram) are available on GitHub at https://github.com/MichaelRColton/PSDR

License Information: The project code is still very much in development. It currently uses the Adafruit GFX and ILI9340 libraries (both being adapted for this application) and is likely to use other libraries in the future. I will comply with any licenses for libraries I include, and plan to license the project itself under a permissive license (like MIT) or a copyleft license like GPL. I would very much appreciate suggests on this.

About the PSDR1: There were a lot of subcircuits that I had never tested for this project (and were hard to breadboard at the frequencies and sizes involved) so I built the PSDR1 board you see here to demonstrate all those parts. I left off the easy stuff (like a battery charger, the whole GPS sub system) and a few of the more advanced parts (like the RF switching, and phase and amplitude measurement IC) Also, while the LCD module was expedient, the next version will have it integrated directly.

    So I get home yesterday to find an unexpected package. Inside is a Ham Radio magazine (The December 2014 issue of Funk Amateur, I like the name!) with a note.... all in German. Sweet! I flip through it and to my shock, I find the PSDR! WHAAAAT!? What a cool thing! (I'd scan the whole thing, but that might be verboten, copyright stuff, you know.) I googled to see if the article was online, didn't find it, but did find a mention of the PortableSDR here.

    The Kickstarter campaign is off to a great start! Last I looked it was almost to $12,000 (20% of the goal) at this rate it will be successful! Thank you so much everyone for your support!

    I am getting a lot of messages, and I am trying to get caught up on posts and things, I hope to get caught up soon.

     

  • KickStarter! Finally!

    PortableSDR on Kickstarter

    Now you guys can finally get it! Sorry it took so long! Thanks for your patience and support eveyone!

    For all of you who are itching to have one (bless your hearts) click here! 

    The internal speaker works now, btw (not great, but it's a start). Also, I have some ideas for a pretty cool 4 band antenna that doesn't need a tuner.

    Hi fans!

    I just wanted to make a quick post here to let you know that I am still here. I wanted to have the Kickstarter live by now, but I really need to get some quotes back on PCB manufacturing, or I wont be able to set the prices with any confidence. I am so excited to get these out into the world, but I don't want to go broke doing it, you know?

    I have an initial quote on the metals (though I want to change the design a little bit) and have been meeting with a local PCB assembly house. I've worked with them (as well as many others) for other projects and have found their work to be absolutely amazing. They cost a little more, but I think it will be worth it in boards that will work well for a long time. Also, since they're local, I won't have to pay for shipping, wait for shipping, or, for example, fly to China (I'm dying to go, but not on my own dime, you see).

    I hope to have a quote back from them soon. When I've got everything figured out, you'll be the first to know!
