One comment on the 'supposed' noise levels with AM. Other than when I was working in rooms with multiple computers (both at HFS and ASU), I have had, and still have, few problems receiving AM stations on my portable receivers either at home or in motor vehicles. Now I realize that most people listen online at their work places, but, from my personal experience, the claims about AM being noisy in general are really overblown. And I suspect that many of these claims are coming from groups that are trying their damndest (and possibly succeeding) to stop people from listening to free over-the-air radio in favor of radio that comes with a monthly service fee.
