uSDR is a general purpose multimode software defined radio receiver Windows application. "u" (μ) means micro becuase of lightweight binaries distributive, simple and compact user interface, highly optimized DSP routines to minimize CPU usage. Compatible with RTL-SDR, AirSpy, BladeRF, HackRF, LimeSDR, Fobos SDR frontends. Able to perform input IQ streaming, base band and pass band recording, play back, demodulation, spectrum and waterfall visualization, animated spectrum navigation, fast zoom and pan. Tehe most of parameters (input frontend, audio device, sample rates ect.) may be changed on the fly, no application hang-up or restart. Under development and a lot of features comming soon.

I was directed to use this program because I bought a Fobos SDR and this is supposed to natively support the device. I don't see any documentation, nor do I see a way to contact anyone. I have issues. 1) When I select the Input to RF (which is VHF and up) I can select any frequency (assuming the section at the top controls the frequency), but I don't get any audio. 2) When I select the Input to HF1, the frequency is locked at 25MHz, and again, no audio.Waterfall looks like there may be activity. 3) When I select the Input to HF2, which doesn't have an antenna, the watefall looks like what I would expect. Again the frequency is locked. Perhaps I have a setting wrong but I can't seem to find any documentation.

Hello! Thank you for your work on this project. Everything is convenient and simple. However, there is one caveat. On the original V3 devices, it works perfectly, but if you use the RTL-SDR V4, the tuning frequency doesn't match the on-air signal, meaning the signal lags about 50 MHz below the set value.

Very good!

That's a great SDR, a real gem! It's writen in Delphi which makes it as fast as C++ with a great GUI. No third party frameworks, just the bare minimum of the native dlls. Sorry C#/Python SDRs... Viol, is there a way to contact you somehow? Erik Skyes
