- This issue is talked about here. AM uses lower frequencies meaning that the waves travel further, but have less "penetration" through obstacles. FM has greater penetration (meaning that it is less affected by a concrete wall for instance). AM radio is also capable of skipping. Cacophony 00:56, 14 July 2006 (UTC)
- Another thing to keep in mind is that the sun ionizes the ionosphere in the upper atmosphere, causing it to be a electromagnetic "mirror". As AM waves travel upward, and due to their lower frequency, they bounce off this mirror and allow the waves to travel further. See here and here for examples. 12.166.203.254 14:17, 23 August 2007 (UTC)

[edit] Merging
No. Those are seperate topics which should have seperate articles. No merging needed. Falkonry 14:20, 23 August 2007 (UTC)
Agreed, and as there have been no further comments in almost a year I'm removing the tag. NPalmius (talk) 02:15, 6 February 2008 (UTC)
