Frequency allocations

  • Region 1 comprises Europe, Africa, the Middle East west of the Persian Gulf including Iraq, the former Soviet Union and Mongolia. The western boundary is defined by Line B.
  • Region 2 covers the Americas, Greenland and some of the eastern Pacific Islands. The eastern boundary is defined by Line B.
  • Region 3 contains most of non-former-Soviet-Union Asia, east of and including Iran, and most of Oceania.

Lines:

Line B is a line running from the North Pole along meridian 10° West of Greenwich to its intersection with parallel 72° North; thence by great circle arc to the intersection of meridian 50° West and parallel 40° North; thence by great circle arc to the intersection of meridian 20° West and parallel 10° South; thence along meridian 20° West to the South Pole.

THF Sub-mm Some administrations have authorized spectrum for amateur use in this region.
  1. This is not mentioned in the ITU’s Table of Frequency Allocations, but individual administrations may make allocations under Article 4.4 of the ITU Radio Regulations.
  2. HF allocation created at the 1979 World Administrative Radio Conference. These are commonly called the “WARC bands”.
  3. This includes a currently active footnote allocation mentioned in the ITU’s Table of Frequency Allocations.
