US And International Tables Of Frequency Allocations (Rev.9/95)

This table is the frequency chart for the US and International assigned and allocated frequencies below 27.500 megahertz. It requires a browser capable of viewing HTML tables (such as Netscape version 1.1 or greater, or Internet Explorer 1.1 or greater). Because of the extreme size of this chart, you will have to use the scroll bars to see all of it vertically and horizontally. You may also wish to see the tables that include a general introduction to all of the frequency information, frequencies 27.5 MHz to 10 GHz and frequencies above 10 GHz. There are also footnotes covering US, International, government and non-government information.
