rtl-sdr.com – A blog about RTL-SDR (RTL2832U) and cheap software defined radio

The High Performance Software
Defined Radio (HPSDR) project is an open source SDR project that aims to
create a modular SDR for ham radio use. The idea is that users only need to
include the specific HPSDR hardware that they need for their particular
application.

Recently, Richard Koch has written a Linux based tool called RTL_HPSDR which allows RTL-SDR based dongles to be used with
HPSDR software, such as cuSDR64 which is capable of displaying and
controlling up to seven receiver slices simultaneously and PowerSDR which can
display and control up to four.

Using his tool Richard was able to get seven R820T RTL-SDR dongles
running simultaneously on an EKB311 Quad core ARM Cortex A9 based mini-pc
using a USB 2.0 hub with a modified power supply to provide 5V@2A.
