Twice now, I've gotten false positive "sink rate" alerts from ForeFlight when paired to my gdl39. It showed up in the track log as altitude dropping out and the lat/long getting noisy for a few minutes. I don't recall anything like this happening with the internal iphone/ipad gps. No interference testing going on, and my ads-b tracks look clean.
