5. Contest Exchange:
5.1. IARU member society HQ stations send signal report and official IARU member society abbreviation. IARU International Secretariat club station NU1AW counts as a HQ station. Members of the IARU Administrative Council and the three IARU regional Executive committees send “AC,” “R1,””R2,” and “R3” as appropriate.
5.2. All others send signal report and ITU zone.
5.3. A complete exchange must be logged for each valid QSO.

6.1. The same station may be worked once per mode per band for QSO credit.
6.1.1. Mixed-mode entries may work a station once per mode per band.
6.2. A station may only be worked for credit in the portion of the band that is generally accepted for the mode used.
6.2.1. On any band, a station may be worked once on Phone (in the Phone segment) and once on CW (in the CW segment).
6.2.2. Cross mode, cross band and repeater contacts are not valid QSOs.
6.3. Where contest-preferred segments are incorporated into regional band plans, participants must observe them.
6.4. The use of non-amateur radio means of communications (e.g. telephone or the Internet) for the purpose of soliciting a contact (or contacts) during the contest period is inconsistent with the spirit and intent of these rules.
6.5. Use of self-spotting techniques on packet or other mediums are inconsistent with the spirit and intent of these rules.

8.1. IARU member society HQ stations and officials do not count for zone multipliers.
8.2. To qualify as the special multiplier, Administrative Council and Regional Executive Committee stations must only be operated by the individual station licensee as a single operator entry or as a multi operator, single transmitter entry with significant participation by the licensee.
