I am receiving some false signals and wondering why and how to fix


All receivers have “spurs” nothing unusual.

If it’s a very strong signal causing overload, then the only fix is to turn down the gain, or add attenuation. But you don’t really need to worry about these images unless they happen to fall on top of your signal of interest.

For anyone that may be having this issue

Cause: I tethered my Pi5 via USB to my hotpot puck and the USB cable was crossing the antenna coax, once properly spaced all the interference went away

Interferrence can come from many places - My Ecoflow power banks jam several bands when charging, so do my threadmil - the transformer i producing close spaced harmonics on 10 meters.

Try turning off other appliances and LED lights
