Zrejme sa na OK-OM DX SSB contest na Slovensku pozabudlo, lebo avízo nájdete na http://www.okomdx.crk.cz , ale na kv.szr.sk alebo Ham radio.sk nie:
1. Organizer
Český rádioklub (ČRK) v spolupráci so Slovenským zväzom rádioamatérov (SZR) vyhlasuje medzinárodné preteky „OK-OM DX SSB contest 2026“.

Always the second full weekend in April. So from April 11, 2026 12:00 UTC to April 12, 2026 11:59 UTC.
3. Categories:
SOAB - one operator - all bands - power up to 1500 W
SOAB - one operator - all bands - power up to 100 W
SOAB - Single Operator - All Bands - Performance QRP up to 5 W
SOSB - one operator - one band (6 bands: 160, 80, 40, 20, 15, 10 m), categories: HP, LP, QRP
MOST - multiple operators, one transmitter
MO2T – more operators, two transmitters
SWL - listeners - all bands
All bands 1.8-28 MHz except bands WARC.
3.1 The participant can participate in the full-band category and several single-band categories at the same time. He can enter up to seven categories (all bands, 160m, 80m, 40m, 20m, 15m, 10m) and get up to six diplomas.
3.2 Participants who take part in the race on only one band, but establish connections on other bands as well, will also send the diary from the other bands for checking.
3.3 Participants are divided into: world, Europe, OK+OM.
4. General rules
4.1 Transmitters and receivers must be located in a circle with a maximum diameter of 500 m and all antennas must be connected to the device with cables (power supplies).
4.2 All categories allow free use of packets and WEB-clusters.
4.3 The use of the IP network for remote reception, including internet radio stations for remote reception, is unsportsmanlike and is grounds for disqualification.
4.4 Self-spotting is not allowed. Negotiating connections using the telephone, the Internet and other similar means before and during the race is prohibited.
4.5 The use of other brands to maintain the working frequency on other bands, to negotiate skeds and to negotiate retuning to obtain multipliers is prohibited.
4.6 One operator may retune bands without restriction - he may transmit only one signal at any given time.
4.7 Stanica v kategórii jeden operátor je stanica obsluhovaná iba jednou osobou, ktorá vykonáva všetko spojené s prevádzkou stanice, t. j. prevádzku, logovanie a prácu s clustrom.
4.8 MOST stations are limited by the ten-minute rule. The initial time is determined by the moment of the first connection on the given band. Only one signal may be transmitted at any time. An exception is the signal on the next band, but only when establishing a connection with a new multiplier. This other band is also limited by the ten-minute rule and it is not allowed to call a challenge on this other band. If connections are established that contradict this provision, they may be listed in the diary, but they will not be counted or penalized; they will be used for control and will be countable for the counter station.
4.9 MO2T (Multi Op, two transmitters): Maximum of two transmitted signals on two different bands at any time. Each transmitter can be retuned from band to band eight times per hour (00-59 minutes of the hour). For example, changing from 40 m to 80 m - here the connection and back again represent two retunings. Both stations can make any connections.
5. Competition code:
5.1 Stations outside OK-OM: report + connection number starting from 001.
5.1.1 MOST can use numbering overall or on each band separately.
5.1.2 MO2Ts may use numbering either on each band separately or for each station separately. Connections for each station must be marked in the LOG.
5.2 OK + OM station: report + district emblem (three letters).
6. Points for connection:
6.1 OK + OM stations:
QSO with own country – 2 points
QSO with another country on own continent - 3 points
QSO with another continent - 5 points
Note: OK and OM are different countries DXCC, QSO OK-OM pays for 3 points.
6.2 Stations outside OK – OM:
QSO with OK + OM station – 10 points
QSO with own country - 1 point
QSO with another country on own continent - 3 points
QSO with another continent - 5 points
6.3 /MM stations do not pay for the multiplier, but they always pay for 5 points.
6.4 SWL stations must record one or both stations in connection, otherwise the same rules apply to them.
7. Duplicate connections:
7.1 Duplication is a connection established repeatedly with the same station on the same band. If the first connection is valid, each subsequent connection is worth 0 points. If the first connection is invalid, the next connection is valid.
7.2 Duplicates are listed in the race diary. It is not necessary to label them.
8. Multipliers:
Two types of multipliers are used:
each OK and OM district on each band separately,
each country DXCC and WAE on each band separately.
9. Total score:
The total score is the product of the connection points multiplied by the sum of both types of multipliers (OK/OM districts + DXCC/WAE countries). The total score is calculated by the organizer after completion of computer processing.
10. Conditions for receiving logs (LOGs):
10.1 Logs are accepted only electronically in format Cabrillo.
