The biggest radio amateur DX contest of the year is coming — CQ World Wide DX Contest v móde CW pre rok 2025 sa uskutoční v dňoch 29.–30. novembra podľa oficiálnych pravidiel. Contest trvá 48 hodín (od 00:00 UTC sobota do 23:59 UTC nedeľa) a je otvorený pre amatérov celého sveta, aby nadviazali čo najviac spojení v čo najväčšom počte krajín (DXCC entít) a CQ zón.
The rules define the permitted bands: 1.8 MHz, 3.5 MHz, 7 MHz, 14 MHz, 21 MHz and 28 MHz, while it is recommended to follow the established IARU band plán.

Pri výmene v CW móde sa odosiela report RST + CQ zone number (eg "599 05"). Scoring is then based on the sum QSO bodov a násobičov (zón + krajín).
In addition, according to the news for 2025, important changes are introduced — for example, audio recordings will be required for top stations, as well as a request for a description of the station layout, including antennas, power and switches.
Particularly interesting are the announced DX stations that are planning to participate in this contest. Among them are less common entities that will attract DX hunters:
- EK8A (Armenia, CQ zone 21) – operation from OK1DTP under the mark EK/OK1DTP
- P44W (Aruba, Zone 09) – a new DX entity that could bring high interest among contest operators
- CR2M (Azores, zone 14) – M/2 station that often attracts distant connections from the islands.
- TY5FR (Benin, zone 35) - DL1BUG operation
- PJ4A (Bonaire, zone 09) – multi-operator under the KU8E team
- TK0C (Corsica, zone 14) – multi-multi station with team including S55OO
- TI5/VA3RA (Costa Rica, zone 07) - offers CW operation, reported by VE3IKV
Pre rádioamatérov to znamená nielen možnosť zaznamenať exotické stanice, ale aj skvelú príležitosť otestovať antény, stratégiu prevádzky a svoju výkonnosť v CW. Ak sa chystáš na CQ WW DX contest 2025 – priprav sa, naber silu, pripoj antény a pohodlne sa usaď. Tento víkend bude naozaj veľký.
CW: 29th-30th November
Start: Saturday 00:00:00 UTC End: Sunday 23:59:59 UTC

X. INSTRUCTIONS FOR LOGS
- The electronic log must be submitted in Cabrillo format.
Full information on the Cabrillo format and a sample file for CQ WW are available at:
👉 https://cqww.com/logs.htm - Each connection (QSO) must contain this data:
- date,
- time (in UTC),
- band,
- operating mode,
- call sign of the other station
- Transmitted report (RST or RS) and zone,
- Received report and zone.
- Denníky pre všetky pásma (All Band) must contain all contacts made during the contest, including those that were not scored (e.g. duplicate contacts).
- Duplicate connections (DUPES) sa nemajú odstraňovať – nebudú penalizované.
- Denníky musia obsahovať presné časové údaje; rozdiel väčší než 5 minút between two logs may cause stratu bodov za dané spojenie.
- Denníky pre kategóriu Multi-Op must clearly indicate which transmitter or signal (RUN or MULT) made each contact.
- If more than one operator is used at the station, all must be listed v hlavičke denníka (Cabrillo header) v poli
OPERATORS: - Všetky denníky musia byť uploaded through the website:
👉 https://cqww.com/logcheck/After uploading the log, the participant will receive a confirmation of receipt. - The deadline for submitting logs is within 5 days po skončení súťaže:
- SSB: by October 31, 2025, 23:59:59 UTC
- CW: by December 5, 2025, 23:59:59 UTC
- Participants who do not submit their log on time may only be included as ako Checklog (kontrolný denník).
- If a participant needs to correct or supplement the log after submission, they can use the form at the same link (https://cqww.com/logcheck/) - clearly marked as opravený denník (corrected log).
- If a participant submits more than one log for the same call sign and category, posledný prijatý denník bude považovaný za platný.
- Participants who do not use the Cabrillo format, môžu byť vylúčení z oficiálneho vyhodnotenia alebo zaradení iba ako Checklog.

XI. LOG CHECKING
- All logs are subject to automatic checking.
For this purpose, computer algorithms are used to compare contacts received between participants and verify the correctness of call signs, zones, and time details. - Contacts that are not confirmed in the opposite station's log sa považujú za neplatné (NIL – Not In Log) a nula bodov sa za ne udeľuje.
Such a connection can also lead to penalizácii v celkovom skóre. - Chybne prijaté volacie značky (tzv. bust calls) alebo nesprávne zóny will also be penalized -
usually by losing points for the given QSO and ďalšou bodovou penalizáciou vo výške rovnakého počtu bodov. - Duplicate connections (DUPES) nebudú penalizované, ale nepridávajú žiadne body ani násobiče.
- Out of band connections (Out of band, Out of time) alebo zrejme neplatné údaje môžu byť vylúčené zo skóre bez penalizácie.
- Rozdiel v čase spojenia between two logs greater than 5 minút sa považuje za chybu a dané QSO sa nebude počítať.
- Final decision on the validity of the log and the result prijíma Výbor CQ WW DX Contestu (CQ WW Contest Committee).
Committee decisions are konečné a záväzné. - Participants who violate the rules môžu byť:
- diskvalifikovaní (DQ) - their score will not be counted and they will not be listed in the results, or
- zaradení iba ako Checklog bez oficiálneho hodnotenia.
- Disqualified participants will not be eligible to receive any certificates, plaques, or other awards,
a ich denníky môžu byť zverejnené on the competition website with the corresponding reason for disqualification.
