I've recently connected a 24V power supply to the big MOSFET driving my heated bed and hotend. The heat-up times are shorter now, which is good. However, I now pick up noise on the AM radio that I listen to while printing. Most of the noise is associated with the PID switching of the hotend. Can I put in some sort of filter or capacitor to make the noise go away?

Try to make sure there are no loops in your wires, maybe install some ferrite somewhere, or get a better quality power supply, or install the radio further away
