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.

    Perfect, It’s really lightweight and to my surprise it works perfect under Windows XP! All it need’s now is a way to lock the side panel in place and a Bandplan on the FTT and maybe a frequency manager, Thanks!

    Every new software that never lists support for sdrplay just makes me sigh internally and sigh dramatically.

    This SDR application is a breath of fresh air, no bloat and no dependancy-hell. It’s a stand-alone application, just unzip the download file and double-click uSDR.exe to run it. VirusTotal cames back with a clean 0/61 scan result for my uSDR_0.1.3.0.zip download file. I can’t find any documentation but if you have used any other mainstream SDR app, uSDR operation will be intuitive. One thing to note, move the mouse cursor to the left edge of the display and the auto-hide configuration panel will fly out. That’s the ony thing that bothers me, I can’t find an option to turn off the auto-hide panel behavior. I prefer an always visible panel. It looks like the configuration options are stored in the simple plain-text Application.CONFIG file. Thank you Viol Tailer!

    That’s a great SDR! It’s written in Delphi and is as fast as C++ with a great GUI. No bloaded frameworks, just the bare minimum of native dlls. The best Windows SDR I’ve ever seen!

    Viol, is there a way to contact you directly?
