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 (but inaccurate) SDR, you can use the DVB-T USB stick using the RTL2832U chip, as documented in rtl-sdr.

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

The hardware is currently in prototype stage. As soon as it is finished, we will make it available through  http://shop.sysmocom.de/

First 16 OsmoSDR boards available for developers

There are something like 16 units of OsmoSDR that we have produce and which are able to sell to interested developers.

However, as there are only 16 units right now, and as the firmware and host software is in a barely usable but incomplete state, we would like to make sure that those 16 units get sold to people who actually have an interest (a ...

Introducing RTL-SDR

While the OsmoSDR is still not available, some Osmocom team members (notably Steve Markgraf) have been hacking away on an alternative least-cost solution: rtl-sdr.

So what is rtl-sdr? It is a creative form of using consumer-grade DVB-T USB receivers, turning them into fully-fledged software defined radios.

Those ...

OsmoSDR hardware verification at 28C3

At  28c3, the OsmoSDR team was busy verifying the hardware design on the first prototypes.

The result can be summarized as:

• SAM3U is working, enumerates on USB and can be programmed via SAM-BA
• E4K tuner driver is working
• Si570 driver is working
• FPGA can be flashed via JTAG bit-banging from SAM3 ...
