Spent an afternoon at Seven Commandos Beach on the Island of Palawan in the tropical Pacific. Turns out there were several of us who had DJI drones. We all were suffering some kind of interference or jamming. It was pretty weird, as the telemetry was screwed up, and there were all kinds of warnings. I was the only one willing to fly in Attitude mode, so I flew this manually. What's really strange is that Seven Commandos Beach is very isolated, not even power-grid electricity running to the beach. Maybe some geologic phenomenon...electromagnetic vortex from the earth's core!
