PortableSDR - A Stand Alone HF Software Defined Transciever. PortableSDR - A Stand Alone HF Software Defined Transciever.
[Hackaday.io Link](https://hackaday.io/project/1538-portablesdr)
The PortableSDR is an all-in-one solution for ham operators, hikers, backpackers, and DIY enthusiasts who are looking for an open-source QRP (low-power) radio for communication. It is a fully stand-alone HF/Shortwave Software Defined Radio (SDR) Transceiver and includes a Vector Network Analyzer and Antenna Analyzer as well as GPS, perfect for portable operations in a variety of conditions. It is designed to be a flexible platform for development, a learning aid, and and a useful instrument for electronics enthusiasts.
## Features
Firmware Build Notes - Coverage from 0 to 35MHz
==================== - Waterfall display that lets you see radio signals
- Receives AM, USB (Upper Side Band), LSB (Lower Side Band), and Morse code (CW)
- Modulates USB and LSB signals
- Variable bandpass filter
* Install gcc-arm-none-eabi: apt-get install gcc-arm-none-eabi, or download from https://launchpad.net/gcc-arm-embedded/4.7 ## Hardware
* Download Eclipse Kepler, v4.3 for C/C++ dev from https://eclipse.org/downloads/packages/release/Kepler/SR2
* Help -> Install New software
* add Name: GNU ARM, Location: http://gnuarmeclipse.sourceforge.net/updates
* Click the radio button, and hit next, next, agree to the license, finsh, Hit OK to allow unsigned contents
* Restart eclipse
* Help -> Install New Software
* same as before,add: Name: Zylin Embedded CDT, Location: http://opensource.zylin.com/zylincdt
* sudo apt-get install openocd
* File -> import -> Existing Projects into Workspace (May be a better way here!)
* Navigate to the PSDR/Source directory and add it.
* hit Build All
You should end up with PSDR/Source/Debug/PSDR.elf which is the binary firmware file - Powerful ARM processor
- Color LCD display
- Dual DDS frequency Synthesizers
- Quadrature Sampling Detector & Exciter
- Digitally controllable instrumentation amplifiers
- Morse Code key (the "Giblet" on the bottom right corner of the enclosure)
- Magnitude & Phase measurement chip (for VNA and antenna analysis functions) with Impedance Bridge
- Dual SMA connectors, smartphone style earphone/microphone connector, and USB port
- GPS
- Built in Microphone and Speaker
- Internal Lithium Polymer battery with charger and high efficiency switching regulator
- MicroSD slot
- Pads for grabbing raw I/Q signals, both in and out.
TODO: Flashing firmware to the PSDR instructions ## Why did I make it?
I'm an avid backpacker and radio enthusiast. To me there is something exciting about making contact with others from remote locations where cell phones and the internet can't reach. I wanted an advanced radio that was ideally suited to tough environments. That meant I it needed to be very compact, integrated, and durable. As an engineer, I wanted an open platform that really takes advantage of the hardware and has the potential to grow and be used for other applications.
There are numerous, excellent radios out there, but none offered the combination I wanted. The best radios are closed source, larger, and expensive, while most open designs are very basic and lacking in flexibility.

Please read our [Contributing.md](CONTRIBUTING.md) for ways to help keep this project going.
New Architecture Build Instructions (WIP):
Windows:
1. Install the GNU Tools ARM Embedded. Add bin (not arm-none-eabi/bin) to path?
2. Navigate to firmware directory in shell and execute: make
3. Use whatever editor you want for the files
For eclipse:
1. File->New->Project...
2. C/C++->Makefule Project with Existing Code, "Next"
3. Browse to the root directory of the PSDR firmware
4. I have been selecting "Cross ARM GCC" not sure if that's needed. "Next"
5. Right click on the project in the Project Explorer and select settings. In C/C++ Build, uncheck "Use default build command" and type "make" (or "make VERBOSE=1") without the quotes. Clock "OK"
6. Try to build the project: CTRL-B or Project Menu->Build-All or right click on the project->Build Project
7. TODO: Set up debugging. Fix all the error messages that come up.
For some reason this doesn't work for me unless I build it at least once from the command line. Also, if I do a make clean, I have to build from the command line. More to learn!
