PageOutline = Welcome to OsmoSDR =

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 [wiki:rtl-sdr].

It consists of a USB-attached [wiki:Hardware], associated [wiki:Firmware]
as well as [wiki:GrOsmoSDR] gnuradio integration on the PC.

The first generation hardware (1.2 MS/s) is available to interested developers from

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 * clone the repository like this: {{{git clone git://}}} * web-browse the repository: []

For a complete list of local wiki pages, see TitleIndex.


This is a (slightly better) picture of the current developer preview:
