I always found it slightly suspicious how the EDGES dip was right between the ITU region 3 broadcast bands. Obviously they do filtering and are far away from everything, but perhaps the gazillion FM stations in Indonesia + some TV stations + meteor scatter (or some other sort of odd propagation) could maybe escape the RFI filtering and mimic the dip.

A rusty bolt on a gutter on a completely unrelated building near a couple of transmitters may be all it takes to re-radiate a signal in a completely different band.
