Summer 2018 I read about UHF-Satcom pirates.
RTL-SDR.COM explains: “The UHF-Satcom band is anywhere between 243 – 270 MHz and contains fairly strong signals from many several US satellites that can be received with a simple antenna. Some of the satellites are simple repeaters without security, and pirates from Mexico and South America often hijack the satellite for their own personal use.”
