The list I gave can also be extended, up to SHF etc., and down to ELF
(.3 - 3 kHz) but I don't know what would -officially- be below _that_.
What I gave were the ITU (formerly CCITT) designations. Of course,
everyone is more or less free to make their own division. For instance,
not everyone is confident that 30.1 MHz is really VHF, hi. And most coast
stations call everything below 4 MHz "MF"; HF beginning with channel 401.
Reading ITU papers can be boring, but you do find some good stuff now and
then, such as the definition of the amateur service, and such.
Especially the footnotes can be quite entertaining. With effort, you can
prove that the dreaded "C", "P" and other beacons in the 40m band are not
really illegal. Of course, we amateurs don't stress that aspect..
