NTIA Frequency Allocations

These are the "official" government allocations for 3 kHz - 30 MHz
in the United States.  Often, they reflect ITU/WARC/WRC assignments,
which have the strength of treaty in the USA.

As always, not everything you hear conforms precisely to band plans
that are set down on paper.  Radio is rarely that simple.
