I had a 50 minute flight a couple of weeks ago and instead of going direct I decided to fly from airport to airport along the way. This ended up requiring a number of turns during my flight and led to handful of false positives from my own plane. I also had a false postive on the way back during the descent I believe. Anyhow, I was wondering if it would be possible to filter out ghost traffic by using my own transponder code (I think that's included in the ADS-B stream)?
