Pilot ever saw anything with the TA alerts.  "Good job by all." 

Captain Steve! This channel is such a great antidote to the insanity going on right now (at least in the US). Thank you for the awesome, interesting, and heartwarming videos. Keep flyin' safe, my brother!

Im a controller. This has occured at my facility. They blamed on testing of a miscalibrated transmitter. Basically one on the ground was tx the wrong location. We can get ghost primary targets but they are usually related to some sort of interference with the radar like birds, vehicles on overpass etc. Im sure they were visually looking with binoculars too in tower. In relation to birds we would be changing our filters to a setting to be able to see that as well.
