TRAFFIC ANOMOLY ON SKYVIEW

[Xtremeair]

I have an Experimental Skyview Touch with Garmin 330ES transponder and Dynon ADSB. My transponder antenna and ADSB antenna are roughly 36" apart. I am getting a lot of traffic warnings that are just me. Any ideas how to fix this? The set up has the correct data in it as I just checked it again.
Thanks!

This from 2021, a simple search -

Have you gone into Setup > Traffic Setup Menu and set the Show Ghost Targets option to NO? (see attached)

Yes, I have done that and verified my registration number correct as to O or 0 (zero). Not sure what else to do at this point. Thanks for you suggestion Andre!

Occasionally I'll pick up my own ADSB while maneuvering tight turns or aerobatics. I've seen double and triple ADSB returns on other aircraft doing aerobatics with unknown systems. Not sure what your doing when you see duplicate ADSB returns... If doing tight maneuvering, it could be inherent to the fidelity of the current system.

It's not a fault of your aircraft - it's the ground system not keeping track of your aircraft during maneuvering. When that happens the ground systems assume you are going straight on the last reported heading and speed, forecasts that forward in time as a "coast" target, and then when you get your aircraft successfully picked up again by the ground station now you are suddenly in close proximity to the other "forecast" track and it gives you a traffic alert.

Higher altitude will help, and make sure your transponder and antenna are doing all they can. An avionics shop can do a VSWR check of the antenna and cabling for that.

Thanks for the info. I have noticed it doing this even in straight and level flight for no apparent reason. I'll see about getting an antenna check.

I know you said you’ve checked your registration but have you also checked your HEX code is the same in your ADSB as your transponder?
