Hi All,
As some of you may know I had a high noise level which appeared intermittant at first then solid. Of recent times it has been a solid S9 on 80mx and S8 on 40mx day and night.I guess the intermittant part was the 11kv power lines out the front so one would think that will continue from time to time. In the finish, I tracked the solid interference down to a standard definition set top digital TV box which was in idle mode 24/7. Even when I disconnected the TV aerial leads (in/out) it didn't change. I tried winding the power lead on a ferrite bar and eventually the TV coax but no effect. The plug pack is not a switching supply either. It just plain seems the plastic cased unit radiates broadband interference and doesn't need an aerial either.
The brand is a "KROSS" Model "DSK530STB" and I would be interested if the same problem is noted with other brands or models.
My noise level has dropped to S4-5 80mx (daytime) and S2-3 40mx. Big difference to my ears.
Would be a shame if one of my neighbours bought one!!!!
