The True Blue DXers Club announces

The 2022 DX Ultra-Marathon

1. DURATION: 1 January 2022 – 31 December 2022


2. OBJECTIVE: For amateurs around the world to contact as many other amateurs in as many countries and CQ WAZ zones as possible.


3. BANDS: QSOs are permitted on all 9 HF Bands 160-10 metres (excluding 60 metres). There are no single-band categories. A special WARC-only leaderboard will be automatically generated listing only QSOs made on 30, 17 and 12 metres, regardless of mode or power category.




A. Score: The final score is the result of the total QSO points multiplied by the sum of zone and country multipliers. Example: 1000 QSO points * (30 Zones + 70 Countries) = 100,000 (final score).


B. QSO points: Stations may be contacted once on each band over the entire duration of the Ultra-Marathon. QSO points are based on the location of the station worked. 

  • Contacts between stations on different continents count three (3) points. 

  • Contacts between stations on the same continent but in different countries count one (1) point. Exception: Contacts between stations in different countries within the North American boundaries count two (2) points. 


  • Contacts between stations in the same country have zero (0) QSO point value, but count for zone and country multiplier credit.

C. MultiplierThere are two types of multipliers:

  • Zone: A multiplier of one (1) for each different CQ Zone contacted on each band.

  • Country: A multiplier of one (1) for each different country contacted on each band. The DXCC entity list, and continental boundaries are the standards for defining country multipliers, as defined by CLUBLOG definitions. Maritime mobile stations count only for a zone multiplier, for this the zone of the /MM station must be included in the ADIF log


5. MODE CATEGORIES: Participants may choose to compete in CW, SSB or MIXED mode.


6. POWER CATEGORIES: Participants may choose to compete at the High Power (HP – above 100 watts), Low Power (LP – up to 100 watts) or QRP (up to 5 watts) power levels.
