All three feeds are powered three Airspy Mini SDRs connected to a single Raspberry Pi 5 SBC. (FYI: 2 Airspy Minis and 1 Airspy R2 didn't work due to random USB power instability once or twice per day in hot weather. Three Airspy Minis plugged into the Raspberry Pi 5 with usb_max_current_enable=1 set in /boot/firmware/config/txt are stable).
