Paul, just the PilotAware - the Kitfox is a bit minimalist when it comes to equipment. I did wonder if it was some sort of reflected signal as the unit was in a temporary housing tucked up on the cargo cover behind my head. I've downloaded the logs, but haven't run them through the viewing app yet.
Peter, I did wonder if it was Keith, but the chaps up at Perth said that he wasn't returning until the Monday.
