Tracking High Altitude Balloons is FUN! But you need to have a decent position to receive the signals. Normally, when at work or at the Delfi-C3 ground station, I have full tracking yagi’s available. But at home I am still constrained by lack of permission to put anything on the roof. So what to do?
Use the car as ground plane!
