This thread gave me an idea. Mu aura is on a shelf with a HDR-1000S about 2" above which is generally powered all day. It's on a seperate glass shelf. All the Mux on my Lark stoke relay are of equal power.
I do get pixellation from time to time both on the DVB-T muxes and the the DVB-T2 mux.
I took an a4 piece of black card and cut out a piece of kitchen foil to the exact size. I folded over the edges about 0.25" all the way round. And taped it down with the folded edges underneath . Inverted the card with the foil underneath and covered the box with the card foil side down. Theory is that the box screening in a plastic box could be poor to a rf source above the box.
Early doors but not seen a flicker all day today. Both recordings and live TV.
All channels meter at 95% signal and 100% quality with no fluctuation.
The coming high pressure system should be a good test.
The box sits on a 4K bluray player which is never used other than to test it's DLNA client when the Aura is powered.So I understand. The 1000s is sitting on the foil card on a shelf with the aura on the shelf underneath?
Thing is, great if it works but this the 21st century and we shouldn’t have to be doing this sort of thing. It’s all a bit “tinfoil hat” for me!but I’ll be following this thread closely.
But I get great signal quality in the morning and the aura doesn’t have pixelation only when the quality mysteriously drops. Does that mean my aura ain’t faulty?No the 1000S is sitting on the glass shelf, The aura is on a lower shelf sitting on top a 4K bluray player, with the foil next to the aura top. Only visible sign is the black card covering the foil.
So far no problems. There are no vents on top of the Aura so zero effect on ventilation. Not had the top of so no idea if there is any screening over the motherboard.
If it works a simple internal screen on the underside of the motherboard may fix it as well.
Thing is all kit like HDMI cables and routers can radiate RF much of it in the UHF band or harmonics.
TBH humax have no chance of checking what we all have. However at the moment it is looking like it is vulnerable. Bring back steel cases.
Glass unless leaded or metallic coated has a minimal attenuation on radiated RF.
Simple enough to repeat the experiment. Just place a peice of foil on the top of the aura.
If you have some thin ferrite sheet it should work even better. Anything a magnet can stick to. Even a layer of tin can lids. You are in good position to test this.
Your issue of course might be totally external.
I remember a faulty street light ballast radiating UHF and blocking TV reception for instance.
The RF screen on coax cable on the best coax cable is copper foil under a copper wire braided screen.

Interesting experiment that might highlight a problem. But how come I had one Aura that had picture break up and a replacement that didn’t? Both were in same position on desk and not on top of another device.
Missing the point. The issue apparently is with a box above the aura but on a seperate shelf, not one underneath. Did not have a single glitch yesterday evening.
