Topband: TV and Monitor Crud

[wa4fki]

Hello Everyone, 

I have pretty much eliminated the local BC stations from my receiver on 160 meters but can anyone please tell how the emissions from TV and computer monitors can be filtered out. 

My shack is surrounded by TV sets (including mine), I can tell when the picture changes by the signal produced by my 160 meter receiver. 

Can a filter be installed like the one used for BC suppression?
