IARU HF World Championship

1) Eligibility	All licensed amateurs worldwide.
2) Object	To contact as many other amateurs, especially IARU member-society HQ stations, around the world as possible using the 160, 80, 40, 20, 15, and 10-meter bands.
3) Date and Contest Period	Second full weekend of July. Begins 1200 UTC Saturday, ends1200 UTC Sunday. Both single and multioperator stations may operate for the entire 24-hour period.
4) Entry Categories	4.1 Single Operator: Categories 4.1.1.1 Phone only 4.1.1.2 CW only 4.1.1.3 Mixed mode 4.1.2 One person performs all operating and logging functions. 4.1.3 Use of spotting nets is not permitted. 4.1.4 All operators must observe the limits of their operstors' licenses at all times. 4.1.5 Single-operator stations ale allowed only one transmitted signal at any given time. 4.2 Multioperator, Single Transmitter, mixed-mode (only). Must remain on a band and mode for at least 10 minutes before changing band or mode. 4.2.2. Only one transmitted signal allowed at any given time. Exception: Only IARU member-society HQ stations may operate simultaneously on more than one band, with one transmitter on each band/mode. Only one HQ station call sign per member-society per frequency band is permitted. 4.2.3. All operators must observe the limits of their operators' licenses at all times.
5) Contest Exchange	5.1. IARU member-society HQ stations send signal report and official IARU member-society abbreviation. IARU club station NU1AW counts as a HQ station. Members of the IARU Administration Council and the three IARU regionla executive committee will send "AC", "R1", "R2", or "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) Valid Contact	6.1. The same station may be worked once per band per mode. Mixed-mode entries may work a station once per mode (but only in the generally accepted portions of that band for that mode. Note: Reworking a station in the phone portion of the band on CW is not permitted). Example: On any band, a station may be worked once on phone and once on CW (in the CW segment) for additional QSO credit. However, this counts as only one multiplier. Crossmode, crossband and repeater QSOs do not count. Where contest-preferred segments are incorporated in regional band plans, participants are required to observe them. 6.2. The use of non-Amateur Radio means of communication (eg, 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 this announcement. Active use of packet clusters (ie. "please come work me" spots or self-spotting) is not within the spirit of the contest.
7) QSO Points	7.1. Contacts within your ITU Zone, as well as QSOs with all IARU HQ member-society stations, count one point. 7.2. Contacts within your continent (but different ITU Zone) count three points. 7.3. Contacts with a different continent count five points.
8) Multipliers	Total number of ITU Zones plus IARU member-society HQ stations worked on each frequency band, with IARU officials representing a maximum of four multipliers per band: AC, R1, R2 and R3. (Note: HQ stations and IARU officials do not count for zone multipliers.)
9) Scoring	Multipliers times the total number of QSO points.
10) Reporting	10.1. Entries must be postmarked or e-mailed no later than 30 days after the end of the contest. No late entries can be accepted. Any entry received after mid-October, even if mailed in time, may not be received in time to be included in the printed results. Use official forms or a reasonable facsimile. You may submit entry on diskette or send your entry to ARRL HQ via Internet. Electronic entries must conform to the ARRL Standard File Formats, (see http://www.arrl.org/contests/announcements/99/rules-all.html ) and should be sent via the Internet to: [email protected] . Any entry which has been generated using a computer must be submitted either as an attachment to an e-mail or on 3.5 inch discette. Any computer generated entry which does not include the log and summary data files will be made a checklog. The files must show your call sign (example: W1AW.log or W1AW.sum) not names like IARU99.sum. The contacts must be listed in chronological order. 10.2.1. Files may be sent as attachments not as the text of an e-mail to [email protected] . 10.2.2. Files may be sent by mail. Foreign entries should use airmail to ensure prompt delivery. 10.2.2.1. Use an MS-DOS formatted disk, 3.5 inch. 10.2.2.2. Diskette labels must clearly indicate the call sign used, contest name, entry class, and date of the contest. 10.2.2.3. Include one entry only on each diskette or e-mail. 10.2.3. They may be sent by Anonymous FTP to: ftp.arrl.org/logs/ . 10.2.3.1. (If you use a non-Web-browser FTP client, FTP to ftp.arrl.org and change directory to /logs , with the command cd/logs.) 10.3. Logs must indicate band, mode, date, time in UTC, calls and complete exchanges (sent and received), multipliers and QSO points. Multipliers should be marked clearly in the log the first time they are worked. 10.4. Paper entries with more than 500 QSOs total must include cross-check sheets (dupe sheets). Contest summary, logs, and cross-check sheet (if required) or diskettes should be sent to IARU HQ, Box 310905, Newington, CT 06131-0905, USA.
11) Awards	11.1. A certificate will be awarded to the high-scoring CW-only, phone-only, mixed-mode and multioperator entrant in each State, each ITU Zone and each DXCC Country. 11.2. Achievement-level awards will be issued to those making at least 250 QSOs or having a multiplier total of 50 or more. 11.3. Additional awards may be made at the discretion of each country's IARU member-society.
12) Conditions of Entry	Each entrant agrees to be bound by the provisions of this announcement, by the regulations of his/her licensing authority and by the decisions of the ARRL Awards Committee, acting for the IARU International Secretariat.
13) Disqualification	An entry may be disqualified if the overall score is reduced by more than 2%. Score reduction does not include correction of arithmetic errors. An entry may be disqualified if more than 2% of duplicates are left in the log. A three-QSO reduction will be assessed for each duplicate QSO found during log checking or for each miscopied call sign.
