Switching power supply is the 'squiggly's' that are moving slowly down the band, changeable in position when you change output voltage of the supply a little bit it'll move for a short period of time and return, then continue to move down the band until it slows and stays in one place. Some of the other  noise is from "wall warts' and such things as cheap diode lights, fluorescent lights, UPS supplies, front loader washing machines, modern furnaces with variable speed fans, Solar systems of just about any size, and the list goes on.
