QSpectrumAnalyzer Updated to Version 1.4.0
QSpectrumAnalyzer is a Linux based opensource GUI front end for rtl_power or rtl_power_fftw and can be used with an RTL-SDR to scan for signal activity on wide swaths of the frequency spectrum. Recently QSpectrumAnalyzer was updated to version 1.4.0 and the new updates add the following features:
- Max peak hold
- Min peak hold
- Spectrum Persistence (RTSA fosphor-like effect)
Previously we posted about QSpectrumAnalyzers ability to use rtl_power_fftw, which is a much faster version of rtl_power. The new features help make the spectrum view clearer especially when using rtl_power_fftw at a very short interval.
This is going to blow my mind when the LimeSDRs come out. Persistence is key.. literally 🙂
