I'm working on a project very near there in two weeks. I'm glad you suggested it. I will bring a spectrum analyzer.
If it's near field coupling at low frequencies, I won't see it with the analyzer. I don't own a near-field probe, but I could just clip half a meter of wire from the ground to signal input of a scope. It will have to be my portable scope and .analyzer.
