Registered user can log in to the site, and their client software will send automatic updates on the currently received radio stations to the database. The connections are visualized on a map. Again, thanks to Andy, HA6NN, we have some pictures about the stations he was receiving with the WSPR Quadrus SDR.
In this post, you see an example of using Quadrus SDR with external software connected through a virtual audio cable. The setup received some DX stations with the DRU-244A SDR hardware, which has enough sensitivity to receive signals from around the word with a simple wire dipole antenna.
The QUADRUS SDR platform is complete ready to use integrated platform for advanced SDR software received implementation. It contains all the elements for a complete SDR receiver functionality. The phase-coherent SDR hardware digitizer with Windows driver and open API. The multi-channel SDR software receiver with advanced signal processing and open programming and remote control interface on TCP/IP. It can be used as a single element or as part of the higher level integrated system. During its entire lifetime already proved capabilities with lot of deployment in mission critical environments. Now it is available for the public use and further integration developments.

Phase-coherent SDR hardware digitizer
The DRU-244A high speed phase-coherent digitizer SDR hardware multi-channel SDR hardware. With on board input leveling, low noise preamplifier and multi-channel SDR digital down conversion (DDC) capability. The DRU-244A SDR hardware has outstanding dynamic range performance with carefully optimized design for SDR hardware implementation. The high-performance SDR hardware design is the combination of high bandwidth and high dynamic range with excellent sensitivity. QUADRUS SDR hardware enables demanding applications such as RF/IF direct sampling SDR receiver. Excellent spectral purity in combination with gain control. The DRU-244A is ideal for advanced digital radio SDR software receiver implementation. Originally developed for professional signal and communication intelligence and spectrum monitoring and management application by Sagax Communications.
Multi-channel SDR software receiver
The SRM-3000 is a ready to run high performance multi-channel SDR software receiver application for the QUADRUS SDR receiver platform. Particularly suitable for spectrum monitoring and management, communication and signal intelligence. It allows simultaneous monitoring and recording multi-channel of modern digital narrow or wide band signals. While the streaming of the IF or the demodulated audio signals can be streamed to the TCP/IP interface. The SDR software receiver has its application programming interface (API) for higher level integration. It combines state-of-the-art user interface technologies with the latest features in digital signal processing thus providing advanced SDR software receiver platforms available today. It was developed by Sagax Communications for search and intercept tasks in signal and communication intelligence applications and deployed to the field in several missions.
