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.
THIRD PARTY SOFTWARE VIRUS WARNING: We just want to note that Khanfar's software shows a few positive results for viruses on VirusTotal. These are most likely false positives, but please use this software at your own risk, especially as it is not 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.
