Has anyone else noticed this from HDMI ports? The reason I ask is that I get some strong noise on 14037KHz from the HDMI on our Sky plus box and TV which is a Sony Bravia. I have tried the usual, ferrite cores, in fact a whole string of type 43 mix clip-on beads along the whole length of the 1m cable, even some FT240-43 rings as close as possible to the output from the Sky box, also different cables in case the screen is different, but none have got rid of it including some very expensive cables. I do get the same on the shack desktop computer on 40m, but to a much lesser degree on 7018.5kHz. I have change the HDMI cable on the desktop computer to a DVI cable, but it is still the same, so I suspect it's coming directly from the Nvidia video card. I was wondering if using an Optical HDMI cable might improve the situation? But they are horrendously expensive and of course I'll be stumped if the interference is being directly radiated from the video board in the Sky box, although I can open it, which I have done before to replace the HDD, it's a bit of a faff because it isn't screwed together, it uses those nasty little tabs you've got to twist to undo the screen box, do that too many times and the tab breaks off I've also got a security camera system from Swann and that HDMI has no radiated noise at all, that I can hear anyway. And that has got a cheap and nasty £1.99 cable on that. It obviously isn't a huge problem because I can work around it, but the interference on 20m is quite strong and dirty, so it spreads out for a kHz either side of the centre frequency. This is a YouTube video of the noise.
