Janos over at embrtlsdr has a new post regarding his work making a Linux powered SDR using RTL based dongles and Ethernet.
“The basic idea was to run the small rtl-sdr util on a small embedded box connected with the dbv-t dongle at near the antenna, and transmit the data on ethernet connection. The more processing and vizualization can be continue on the desktop/laptop machines.
To this setup I choosed my old small linux box, the NSLU2. It has 2 USB conncetors, network connection, and, more than 2 years ago I installed on it a Debian lenny version, on a 4 Gbyte pendrive.”[ LINK ]

Following your propose I reconfigured my basic setup, with more Tux support: this is a “near-movable” version, with wifi connection:
The Tux supports the wireless access of the embedded rtl-sdr server:

Great stuff! Have a couple of Technologic Systems TS-7300 boards I’m hoping to configure for SDR using RTL2832U dongles.

I have a couple of raspberypi’s on the way.
Once I have completed my antenna this will be my next project.
Thanks for details!
