There are so many freqeuncies being tranmitted from up there that there could conceivably be SOME radio controlled devices affected by it. It’s called intermodulation when it crops up on strange frequencies. It involves harmonics and difference frequencies. But it probably is not responsible for more than a few percent of potential explanations. It would be more pronounced beyond the height of the building away from the building, not at the base. There are probably hot spots in other high buildings nearby.
