The interference caused by over-driven FT-8 signals is concerning. The distortion that shows up on either side of the FT8 watering hole is often stronger than the signal one is trying to copy down the band.
The attached image shows an example of the bandwidth occupied by distortion products that are well beyond FT8 operating frequencies.
This has been going on for some time now and it seems most prevalent on weekends when there's lots of activity.
