Now the 64,000 dollar question.
What could be done to suppress them?
Either hide them with software tricks, such as the spur-removal option, but that might leave “holes” in the spectrum, or additional filtering/ decoupling/ screening on the board, which is out of the question for most current owners.
There is of course the human software modification - learn to live with it and adjust practice accordingly.
Out of interest, I was playing with my nanoV2 to improve screening. I found that things seemed to be worse if I applied conductive (absorption) tape inside the case and even laying the device (in FR4 unclad case) on a flat metal sheet also made things worse, especially above 2.5ghz.
