Please note that in order to prevent cheating during DX Expeditions or DXCC huntings there is a 15s delay in the audio feed of this websdr.
The SDR is used primaly for the Reverse Beacon Network and feeds both a CW and an RTTY skimmer.
The stats of the skimmer can be found here : http://www.reversebeacon.net/dxsd1/dxsd1.php?f=0&c=9v1rm&t=de
The CW and RTTY skimmer are running on an i7 8700k system with 16 Gb of memory. The WebSDR software runs on an i5 2500k. The I/Q data are feeded using the CWSL_WebSDR extension from Hardy, DL1GLH : http://www.dl1glh.de/cwsl_websdr.html.
