OsmoSDR is a 100% Free Software based small form-factor inexpensive
SDR (Software Defined Radio) project.
If you are familiar with existing SDR receivers, then OsmoSDR can be thought
of something in between a FunCube Dongle (only 96kHz bandwidth) and a USRP (much more expensive).
For a very cheap SDR (with limited dynamic range), you can use the DVB-T USB stick using the RTL2832U chip, as documented in rtl-sdr.
The first generation hardware (1.2 MS/s) was available to interested developers from http://shop.sysmocom.de/
We are currently doing a re-design for the second-generation hardware, featuring higher sample rate and other goodies.Hardware schematics and firmware source code are kept in a git repository on git.osmocom.org.
- clone the repository like this:
git clone git://git.osmocom.org/osmo-sdr.git
This is a (slightly better) picture of the current developer preview:
