Hermes and Red Pitaya now Supported in OpenWebRX

Thank you to Stefan Dambeck (DC7DS) for submitting news about OpenWebRX adding support for Hermes HPSDR compatible SDRs. Hermes is a single board version of the open source high performance SDR (HPSDR) design. There are several compatible Hermes designs including the newer Hermes-Lite 2 . The Red Pitaya is an open source electronics laboratory instrument, but custom software can be installed allowing it to function as an HPSDR type SDR. OpenWebRX is software which allows you to access your SDR remotely via the internet or local network through a web browser. Stefan notes:

I built a test setup today using a Red Pitaya 125-14 SDR in HPSDR mode, and this is now also supported, see screenshot.

At the moment, only one receive stream is supported, for the red pitaya with 192KHz bandwidth.

RTL_HPSDR: RTL-SDR to HPSDR Translation Server

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 [email protected]
