Thank you very much for all the answers. From what you guys said it
seems to me (please correct me if I'm wrong), that the only consistent
(aka commercial broadcast) in this frequency range would be either AM
broadcast or SW broadcast that also uses AM modulation. There is no
way to guarantee that a certain ham mode will *always* be at a
specific frequency since they are operated by amateur radios, right?

If the above is true, then could anyone provide information / links to
the specifications of SW broadcast? Does it use the bandwidth as AM (
ie. DSB with 10Khz separation between carrier frequencies ) ?

Thank you very much for your help,

Jung.
