   Most AM noise I've found is worse between 700KHZ - 1MHZ.   At my house, the AM   
   is almost unlistenable, and I'm in the middle of a 5 acre lot.  What I found   
   by shutting off all breakers and turning them on  one by one was several items   
   contributing to the    
   din. I found my outdoor motion sensing light fixtures were causing noise (took   
   them apart and hard wired them then added Honeywell wall dusk to dawn   
   switches), my alarm system (added low value capacitors across all keyboard   
   lines at the panel), but the    
   biggest offender was my wifi router.  I took it apart and found the PFC cap   
   bulged and changed it.  It cut the noise down but it still generates a   
   racket.
