Detecting Starlink Satellites with a Portable Raspberry Pi + RTL-SDR

Over on his YouTube channel 'saveitforparts' has in the past created a portable homemade 'tricorder' which was a boxed up Raspberry Pi with multiple sensors including an RTL-SDR. One new application he's found for the tricorder is the ability to detect the beacons from Starlink satellites using the RTL-SDR and an LNB. Starlink beacons typically transmit at around 11.325 GHz, so to receive them with an RTL-SDR a downconverter and antenna such as an LNB is required. In the video he demonstrates t…
