(one person operates the radio station and all other equipment, the use of a DX cluster or similar network is prohibited):
- phone only – QRP, Low a High Power
- CW only - QRP, Low and High Power
- MIX – QRP, Low and High Power
Multi Op
(multiple operators, one transmitter):
- only MIX
- the 10-minute rule applies when changing mode or band
- only one broadcast signal at the same time, it is not allowed to use the second device as a multiplier workplace
IARU HQ station
- one broadcast signal in a given band and mode (160CW, 160FONE, 80CW, 80SSB, etc.)
- all stations participating in the operation of the HQ station must be located in the same ITU zone
Code exchanged
- IARU HQ stations broadcast the report and the official abbreviation of the organization. The IARU Secretariat club station NU1AW counts as the HQ station. Members of the IARU Administrative Committee and the IARU Regional Executive give the abbreviation AC, respectively. R1, R2, R3
- other stations broadcast the report and the ITU zone number
- the completely changed code must be entered in the log book when it is valid QSO
Valid connection
- one station can establish one connection in each mode and band, e.g. Valid QSO on 20m CW and 20m SSB
- competitors are obliged to comply with local regulations, even if they would put them at a disadvantage compared to other competitors
- selfspotting is prohibited, as well as arranging connections by any kind of non-radio amateur connection (e.g. by telephone or Internet)

Scoring
- connection in own ITU zone, as well as HQ station or IARU representative is evaluated with 1 point
- a connection within one ITU zone, but to a different continent, is evaluated with 1 point
- a connection within one's own continent, but another ITU zone, is evaluated with 3 points
- a connection to another continent and another ITU zone at the same time is evaluated with 5 points
Multipliers
- the total number of ITU zones worked plus the number of HQ stations from each band (not mode). IARU representatives represent four possible multipliers.
- HQ stations and IARU representatives do not pay as zone multipliers
The result
The total number of points is determined by the number of points for connections and the number of multipliers

Attention - originally the IARU HF World Championship had a very strict evaluation, where there were significant point deductions up to elimination from the evaluation. Newly, duplicate connections are just crossed out without point deduction. But it is applied for connections that do not pass cross-checking or contain an error in the mark. The deduction is of the same point value as the deleted connection. Due to an error in the exchanged code, the deduction is not applied.
