Graham,

  John and Jay summed it up very nicely.
I'd add that my 160-190 kHz license (WE2XEB) is for cw, ssb and
digital modes - experimental licenses have no set limits, its all what
you can justify and get approved by the FCC.
Part 15 deals mainly with incidental radiators - i.e. switching power
supplies, industrial and consumer equipment which use radio
frequencies but are not intended to radiate. The 160-190 kHz
experimenter band is a nice add-in to those rules.

Note that Jay has a very rf quiet location, I don't think I could
receive many of the long distance 1W stations that Jay does!
