Incoming waves can/will combine with any/all other waves (think magnetosphere, van allen belts, man-made etc) to mix into new frequencies or any combination of frequencies. Think "harmonics" (radio term). A simplified example model would be = LF mixed with HF becomes MF waves (and likely everything in between). Really basic electromagnetic radio principles.
And consider what happened during the last "1859 Carrington Event" where telegraph & power lines became so charged that countless fires broke out in building connected (via cables) to the grid. The next event will be much more widespread because of the wired & interconnected nature of our infrastructure
