I'm a ham so I installed an APRS transmitter in my -8. Somewhere along the line, I screwed it up and it doesn't work...but I see that even if I don't file a flight plan or even contact ATC, my flights are tracked in the same way on FlightAware through all of the ADS-B tracking receivers that are out there (pi-aware, etc). My thinking now is that I'll remove the APRS antenna (reduce some drag), get rid of the in-op transmitter and still have the advantage (if you call it that) of flight tracking whether in the system or not. There are so many pi-aware receivers (and other variants) now, even my "in the pattern" landing practices are logged. The only way to avoid tracking now is to turn your transponder off! Any thoughts on this?
