Linux Embedded RTL-SDR Receiver

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.”
