In 1996, G4BWP of the RSGB's HF Committee made a proposal at the 1996 
Region 1 General Conference Tel Aviv that a common set of boundaries be 
identified for the "ITU regions as used in amateur radio" based upon 
research done  by G3HTA and G3KMA. The RSGB's proposal was accepted at 
the Region 1 Conference in Lillehammer (1999), Region 3 Conference in 
Darwin (2000) and the Region 2 Conference in Guatemala City (2001).

This is the set of boundaries that are tabulated in the Region 1 HF 
Managers Handbook (as previously referenced) and elsewhere.

The irrelevant map showing the ITU HFBC CIRAF zones was removed from the 
published rules the second year of the IARU Radiosport Championship 
(1978); a prefix to zone table (a la the IARU's) appeared in the 
published rules until 2002 when it was moved to the web (from whence it 
disappeared earlier this year).
