  1. Contest period: The second full weekend in November, UTC 1200 Saturday to 1200 Sunday (9.- 10. Nov 2019).
  2. Mode: CW only.
  3. Bands: 1.8 through 28 MHz, except WARC bands.
  4. Categories:
    1. Single operator high power - all band, output power shall not exceed 1500 watts (SOAB HP)
    2. Single operator high power - single band, output power shall not exceed 1500 watts (SOSB HP)
    3. Single operator low power - all band, output power shall not exceed 100 watts (SOAB LP)
    4. Single operator low power - single band, output power shall not exceed 100 watts (SOSB LP)
    5. Single operator - QRP (output power shall not exceed 5 watts, all band only)
    6. Multi operator, single transmitter (MS) - all band, output power shall not exceed 1500 watts
    7. SWL
    DX cluster support is allowed for all categories. Single operator can take part in several categories (e. g. SO AB & SO 20m & SO 80m). For MS: The minimum time to call CQ on a band is 10 minutes. A quick band change in order to work new multiplier is allowed - it is OK to work one station and return to the main band.
  5. Making QSOs: OK/OL/OM stations contact non OK/OL/OM stations. Non OK/OL/OM stations contact OK/OL/OM stations. A station may be worked once per band.
  6. Exchange: OK/OL/OM: RST + district abbreviation (e. g. 599 BPZ). Non OK/OL/OM: RST + progressive QSO number starting with 001.
  7. Multipliers: OK/OL/OM: prefixes following WPX rules on each band. Non OK/OL/OM: districts on each band.
  8. QSO points: Foreign (non OK/OL/OM) participants from EU countries (use CQ WW rules for continent) earn 1 point for QSO with any OK/OL/OM stations. Foreign participants from DX countries earn 3 points for QSO with any OK/OL/OM stations. OK/OL/OM stations earn 1 point for QSO with EU and 3 points for QSO with DX stations.
  9. Score: The final score is the sum of QSO points from all bands multiplied by the sum of multipliers from all bands.
  10. Rules for SWLs (non OK/OL/OM): Each correctly logged QSO (date, UTC, band, call-sign OK/OL/OM, district, call-sign non OK/OL/OM) per band counts 1 point (EU SWLs) or 3 points (non EU SWLs). SWL multipliers: OK/OL/OM districts on each band. Each OK/OL/OM station may be counted only once per band.
  11. Logs:
    1. All the LOGs must be send within one week from the contest (NOV 17, 2019, 2359 UTC)
    2. LOGs are accepted ONLY in electronic form and only through Web interface.
    3. The paper LOGs are not accepted.
    4. The only accepted format is CABRILLO.
    5. All logs must contain the following data: date, UTC, band, call-sign, transmitted exchange, received exchange
    6. Only one LOG is send - even in the case the participant decides to take part in more cathegories.

  • Clarification for SWL
    Since the CABRILLO format does not support SWL cathegory, it was decided that we will accept SWL LOGs in any reasonable format. Only SWL LOGs can be send via e-mail: okomdx.crk.cz, SWL LOGs are not accepted through the web. Each QSO record must contain: date, UTC, band-frequency, callsign of the station, sent code, callsing of the corresponding station, points, new multiplier.    
    The summary should be part of the LOG and should contain: for each band number of QSOs, points, multipliers. The LOG should contain the cathegories, RIG, e-mail.
  • Disqualification: Violation of contest rules, unsportsmanlike conduct or taking credit for excessive unverifiable QSOs will be deemed sufficient cause for disqualification.
  • LOGs with more than 20% faults could be ommited.
  • All decisions of the contest committee are final. The contest is sponsored by Czech Radio Club (CRC), member of the IARU.
  • Awards: The participants will be awarded in three divisions: OK/OM, EU and DX. In each division and each category there will be list of participants. Awards for all participants will be on the web in printable format (pdf).
    One station can be awarded up to one plaque - for the category, where the maximum of points were achieved. The list of plaques and their donors is developing (look at okomdx.crk.cz) and a lot of categories are still without donors. If you are interested to promote this contest then write to contest committee (e-mail: okomdx@crk.cz).
