IARU member society HQ stations, such as W1AW, send signal reports and official IARU member society abbreviation as listed on the IARU website at https://www.iaru.org/reference/member-societies/ IARU International Secretariat club station NU1AW counts as a HQ station, and sends “IARU”. Members of the IARU Administrative Council and the three IARU regional Executive committees send “AC,” “R1,” ”R2,” and “R3” as appropriate.

All others send signal reports and ITU zones.
