Amateur radio operation EB3FRN demonstrates how he used an RTL-SDR dongle tuned to a distant VHF transmitter as a passive radar receiver to view the echoes produced by the meteor’s ionization. The signal he received was from the Graves radar system on 143.050 MHz, using a VHF ground plane connected to the dongle. He displayed the scatters using Baudline.
