Topband: FT8 qrm - 3khz wideband digital

[HP]

My two cents is - at least with FT8 so far 99.99 percent of the folks stay in the 2 - 3 khz segment . 

I am amazed I see virtually nothing about the proliferation of 3 khz wideband digital two way hash on all HF bands . For instance last night on the ZA1WW on 3536 , it covered both the ZA and most of the pile calling 

And then there is my problem with Century link ADSL carriers every 4 khz across 160-80-40 at 5 to 10 db out of noise. On 80 happens to be 3535.934 - the ZA was about 3535.970 pretty rough . 

Also amazes me I seem to be the only one in the country with the 4 khz combs (which sometimes are just limited to the ham bands bottom edge up 70- 100 khz almost as if intentional )
