OK/OM DX contest patrí medzi významné medzinárodné CW súťaže . V roku 2016 sa koná počas druhého kompletného víkendu v novembri, konkrétne od 12. novembra 2016 12:00 UTC do 13. novembra 2016 11:59 UTC.
The competition is exclusively in CW mode and takes place on all classical amateur bands from 1.8 MHz to 28 MHz, with the exception of WARC bands.

Competition categories
The categories are as follows:
-
SOAB HP (Single Operator All Band High Power): One operator, all bands, power up to 1500 W.
-
SOAB LP (Single Operator All Band Low Power): One operator, all bands, power up to 100 W.
-
SOSB HP (Single Operator Single Band High Power): One operator, one band, power up to 1500 W.
-
SOSB LP (Single Operator Single Band Low Power): One operator, one band, power up to 100 W.
-
QRP (Single Operator QRP): One operator, all bands, power up to 5 W.
-
MS (Multi-Operator Single Transmitter): Multiple operators, one transmitter, all bands, performance according to license terms.
-
SWL (Short Wave Listener): Listeners that log connections without active traffic.
An important feature of the competition is the permission to use the DX cluster in all categories. This allows participants to search for new stations more efficiently and respond quickly to new multipliers. One operator can apply to several categories at the same time, for example a combination of SOAB and SOSB on different bands. For the MS category, the minimum time of operation on one band is defined – 10 minutes, while a quick band change is allowed to obtain a multiplier and then return to the original band.
Rules for making QSOs
Establishing connections is strictly defined according to the geographical origin of the stations. Stations from the Czech and Slovak Republics (OK/OL/OM) can only make QSOs with stations outside these prefixes, while foreign stations can establish connections only with OK/OL/OM stations. Each connection is valid only once on a given band, thus ensuring transparency and fair evaluation for all participants.
Each station transmits a specific code when connecting. OK/OL/OM stations transmit RST plus district emblem (e.g. 599 BPZ), while foreign stations transmit RST plus connection sequence number starting with the number 001. This methodology enables accurate tracking of connections and facilitates checking of results.
Multipliers and scoring
The competition uses the concept of multipliers, which significantly affects the final result. For OK/OL/OM stations, the multipliers are prefixes according to the WPX policy on each band, while for foreign stations, the multipliers are individual districts. This system supports active multi-band operation and increases the strategic value of operator planning.
Scoring for connection is governed as follows:
-
OK/OL/OM: QSO with a European station = 1 point, outside Europe = 3 points
-
European stations: QSO with OK/OL/OM = 1 point, outside Europe = 3 points
The total result is calculated as the product of the total number of points and the total number of multipliers. This approach takes into account not only the quantity, but also the geographical diversity of connections, thereby creating a comprehensive picture of the participant's success.
Conclusion
OK/OM DX contest 2016 poskytuje široké možnosti pre všetky úrovne rádioamatérov, od jednotlivcov až po viacčlenné tímy. Vďaka jasne definovaným pravidlám, kategóriám a bodovaciemu systému je súťaž nielen prestížnou udalosťou, ale aj testom technických schopností a strategického myslenia operátorov.
