Sorry that it wasn't that simple Andre
My knowledge and experience is very limited, but it might be worth considering LED lights and televisions - my knowledge is now exhausted.
Best of luck,,,

Have you tried another programme?
It might be worth trying SDRuno, just to exclude the possibility of corruption occuring within your version of HSDR, although it does seem unlikely.
You could try removing the antenna to see what effect it has.
Also, another thought, as you are using a laptop, why not take your equipment outside your dwelling (to an electrically quiet location) and try it with a simple antenna to see whether the interference persists or disappears.
Good luck.

Hi Paul id already test with SDRuno and that gives the same issue. the printscreen you see is without antenne (with is the same).
i wil test it this week outside with my laptop. but other devices here (AOR DV1) etc dont have issues with this.

Hello Andre,
I understand that you have a new USB cable, but unless the cable is well shielded, it will act and an antenna and couple external electrical noise into your unit. Good quality ferrites help considerably with this. Regarding readings on your S-meter, only SDRuno has a calibrated S-meter, so values taken from any other programme will be meaningless.
To eliminate external sources of interference, try plugging your device into a laptop that is running on batteries (if you have a laptop that is) and move a an electrically quiet place, well away from network switches, powerline modems, LED lights, plasma TVs etc. With no antenna connected, If the interference goes away then the problem will be coupling via the USB cable.

If it might help, please post screen shots of what you see with SDRuno, so people can see your settings and the level of interference that is accurately measured.

Sincerely
