Lightweight Windows Software uSDR Updated to Version 1.4.0

Back in July we posted about the release of Viol Tailor's "uSDR" software, which is a lightweight general purpose multimode program for Windows which supports the RTL-SDR, Airspy, BladeRF, HackRF and LimeSDR radios. Recently Viol has updated the software to V1.4.0. The new release brings SDRplay support, and various performance and GUI improvements listed below.

The software can be downloaded from SourceForce.

  • customizable tool panel behavior (fixed, floating, undocked)
  • SDRPlay frontend support (API v.2.13)
  • RTL-TCP streaming interface support, presets quick switch (server, port, description)
  • high precision Wav IQ file play back
  • support RIFF 8, 16, 24 and 32 bits integer, 32 bits float, FR64 file formats for playback
  • recognize Wav IQ file central frequency for play back
  • frequency offset (shift) for x-verters
  • swap IQ (invert spectrum) option
  • improved FFT spectrum calculation and visualization
  • waterfall color map range may be changed manually on the spectrum window as well as on tool panel, also included the auto scale option
  • color map palette can be customized and fast switched, palette presets are included
  • FIFO buffer size (IQ history time) may be changed on the fly, all memory allocations are under hood, no losses of previously stored history 
  • pass band may be attachment to global frequency as well as to local baseband frequency or to screen position
  • squelched threshold control and level indicator for demodulation (in addition to adjustable spectrum threshold detector)
  • stereo FM demodulator
  • low latency audio
  • frequency manager, groups and interactive markers, visualize, edit, navigate, tune the pass band
  • spectrum and waterfall popup menus
  • improved GUI controls
  • "fine tune" option: set pass band to rounded frequency (spectrum right click)
  • statistics visualization window

uSDR: A Lightweight Multimode SDR Receiver Program for Windows

Thank you to Viol Tailor for submitting news about the release of his general purpose multimode software defined radio receiver program for Windows called "uSDR" or "microSDR". Viol writes that uSDR is designed as a lightweight binary with a simple and compact user interface and highly optimized DSP to minimize CPU, hence the "micro" part of the name.

The software is compatible with RTL-SDR, Airspy, BladeRF, HackRF and LimeSDR radios. It has features including demodulation, base band and pass band recording, playback, and spectrum and waterfall visualizations.
