I know with tropospheric ducting and skip, in the radio comunication world, anything can happen. With ADS-B being line of sight....is it completely impossible to get the odd return from far far away?
Occasionally I get the odd return like this.

Jason
I doubt it is anything to do with ducting or anything like that, more like faulty or miss set equipment. A while back Bluebird aircargo frequently used to show as in the middle of Africa sometimes even showing a trail so it could not have been that far from me
