During first use of the ADSB receiver I had what appeared to be a ghost plane offset about 0.3 mi or less from my position. Wondering if anyone else had seen this, and have a suggestion of what could be done. I'm guessing there is a mismatch of the GPS receivers (they were not up against the canopy but we down in the baggage compartment in back,... maybe some signal bounce) Approach had other traffic, but did not mention or call to another that close and following me.
Other than that,... great,.. really useful display and like the alert that says relative position and other info. There were some other real aircraft close aboard.
