RTL-SDR scanner

RTLSDR scan
Al from Ear to Ear Oak has released this open source cross platform Python frequency scanning GUI for the OsmoSDR rtl-sdr library.

The software scans a range of frequencies and plots the result, allowing you to find signals to investigate. The RTL dongle has a maximum bandwith of about 2.8MHz but with this you can scan the full range of the dongle, allowing you to see signals with ease. For example the screen capture shows my local FM radio stations.

Al has posted the code for this project on GitHub.

  1. Alan says:

    If the bandwidth is only 2.8MHz, how did he create a spectrum picture covering 87 – 108 MHz?
    Do you sweep the oscillator in the RTLSDR across the desired spectrum?
    If so, how fast can you go? The speed of the sweep must be combined with the bandwidth to give the best indication of performance.

    If you step the oscillator instead of sweeping, what is the step size & rate?
