My third feed covering 121.5 Air Emergency and mostly civil 122.75 Air to Air radio traffic frequencies. Antenna is located about 20 miles NE of SeaTac airport near Waypoint WOODI.

Scan = "121.5 Emergency", "122.75 Area Air to Air"

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).
