Location Somewhere in my House
Short Description I found out that it was my old thermostat for my central heating. As soon as i pressed a button the signal changed. Replaced it with a new one. Now it is gone.

I can only receive this Signal inside my House. As soon as i leave my yard i am not able to receive it anymore.

Almost a 100% chance that this is EMI.
