Honestly I'm sorta shocked that folks aren't mixing SDR and AI stuff. I guess most folks just don't realize GnuRadio appears to be in distribution for the major models and even post-tariff an RTL-SDR starter kit is under $50 and plugs into any USB.

These are the latest news about RTL-SDR V4... As they say, there will be a new V4(Lite) version of the RTL-SDR. All the supposed V4 actually being sold are just V2's on a V4 enclosure... To be honest the MSI clone I bought is still more effective than any RTL-SDR no mater what version it is...

The DIY QFH antenna made from $40 of pvc pipe, threaded rod, some aluminum strips from home depot and a random tv coax cable I had laying around worked flawlessly!
I'm could not be happier with the results, it captured Cabo San Lucas all the way passed Vancouver!

Khanfar Spectrum Analyzer: Signal Analysis Tools for the RTL-SDR
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.
