What this site does that a PDF does not

Every band, every Region

Open a frequency range and read what is allocated to whom in each ITU Region, with the footnotes that qualify it — instead of scrolling a table of hundreds of pages.

What changed, and which conference changed it

Five editions are reconciled against each other, so a change is not something you reconstruct by comparing two documents. Which WRC made it is part of the data.

In the language it was adopted in

English, French and Spanish are equally authentic and none is a translation. Each language here is taken from the official edition in that language.

Start with the allocation table

Reading the Regulations needs no account. An account exists for one thing: to be told when a conference changes something.
