Thank you to M. Khanfar for submitting news about the release of his new spectrum analyzer, sweeper, and FM Radio demodulator tools for the RTL-SDR. The tools are freely released, however, they do not seem to be open source.

The first tool M. Khanfar is releasing is the Khanfar Full Spectrum RTL-SDR Sweeper tool, a wideband spectrum analyzer for the RTL-SDR. It allows the RTL-SDR to produce a spectrum sweep over a large bandwidth by rapidly re-tuning the frequency and plotting each 2.4 MHz live sweep sequentially. This is the same concept used by previous tools like rtl_power and Spektrum.

The second tool released is the Khanfar Advanced Spectrum Analyzer. This tool allows you to view the live spectrum from an RTL-SDR in various visualization modes.

The third tool is Khanfar-FM-Radio, a text-based wideband and narrowband FM demodulator for the RTL-SDR.

M. Khanfar notes that all tools can open multiple instances of themselves, allowing them to be used use multiple RTL-SDR dongles on the same machine.

In the video embedded below, M. Khanfar shows his three software applications in action.
