I spoke with a friend about this yesterday who was in the area and has done quite a bit using SDR as a radio amateur. He passed along these links:
https://etd.ohiolink.edu/apexprod/rws_etd/send_file/send?accession=wright1608139109925131&disposition=inline https://www.rtl-sdr.com/using-an-rtl-sdr-rf-fingerprinting-and-deep-learning-to-authenticate-rf-devices/ https://www.rtl-sdr.com/identifying-transmitters-with-ctcss-fingerprinting/ The second link is interesting as it focuses on RF devices that are commonly found such as IoT sensors, keyfobs, and other common RF transmitting devices beyond two-way radio transmitters. In other words, this tech should have applicability in network security, to bring it back on topic a bit. - Nate -- "The optimist proclaims that we live in the best of all possible worlds.
