Gary,

If you go here: http://www.overunity.com/index.php?action=downloads
you will find a Frequency Allocation Chart covering all frequencies in the US.
The name of the file is: "US Frequency Allocation Chart".

If you look at the Front Dial of all AM Radios, from the 1930s all the way forward to today, it says:

550 KHz thru 1600 KHz.

Of course the older radios say 550 KC thru 1600 KC (KC for Kilocycles because KiloHertz wasn't adopted before about 1960).

Nice one FB i got that from wikipedia just before Alex's chart was posted.

Seems that AM is split into groups :

        Long wave : 148.5 to 283.5 kHz

   Medium wave : 520 to 1,610 kHz

   Short wave : 1.711 to 30.0 MHz

The medium wave band has been extended to 1710 Khz in ITU region 2 (America).
The 1620 - 1710 band is not used in Europe except by pirate stations, mainly dutch stations.


In the shortwave band 3-30Mhz, only subbands are allowed for broadcasting but there are some stations broadcasting anywhere (especially religious stations, these people have no respect for mankind whose the rules are dictated by international agreements to avoid interferences).

If you want to use HF with strong levels and the frequency is not critical, use ISM frequencies (http://en.wikipedia.org/wiki/ISM_band). The frequencies can be understood as "trash frequencies". They are reported as being not protected and they are not used for communication.
