OK-OM DX Contest Rules

The Czech Radio Club (CRC) has the honour to invite amateurs all over the world to participate in the annual OK-OM DX Contest.

 

  1. Contest period: The second full weekend in November, UTC 1200 Saturday to 1200 Sunday (14. - 15. Nov. 2009, 13. - 14. Nov. 2010, 12. - 13. Nov. 2011).
  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). In this case, it is necessary to send a separate log for each category. 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 logs must contain the following data: date, UTC, band, call-sign, transmitted exchange, received exchange, multiplier (only when first time worked), QSO points for each contact. SWLs log date, UTC, band, call-sign OK/OL/OM, district, call-sign non OK/OL/OM, multiplier (only when first time heard), QSO points for each contact.
    2. Logs must be sorted in chronological order, regardless of band of operation. All-band entries submit a single log of all QSOs. Single-band entries submit one log per band. In case single-band entrant submits an electronic log, a single log is required with QSOs from all used bands and in the summary clearly designate category or all claimed categories. In Cabrillo logs all categories are writen in one line, separated by comma (e.g. "CATEGORY: SINGLE-OP ALL HIGH, SINGLE-OP 10M HIGH") - more info here.
    3. A summary sheet including used callsign, all relevant data needed to calculate final score, description of equipment, power output, full name and address in block capitals and signed statement of compliance must accompany each log. In case the log is submitted on a disk, a paper summary sheet is necessary. If an entrant submits an electronic log, duplicate contacts, QSO points, and multipliers will be calculated automatically by the sponsors.
    4. Every competitor who used computer logging is required to submit a electronic log (computer file). We strongly recommend you submit the Cabrillo file created by all major logging programs. If Cabrillo is unavailable, then submit a summary sheet and your log in plain-text ASCII (two files). Every logging program has the option of producing an ASCII text log. Examples of the ASCII log file names of the three most common logging programs are the following: e. g. OL5Y.CBR (Cabrillo), OL5Y.DAT (N6TR), OL5Y.ALL (CT), OL5Y.PRN (NA), OL5Y.LOG (SD). Acceptable submissions can also include all other fixed-column ASCII formats. Any electronic log is always better then paper log!
    5. We strongly recommend submission of logs via e-mail. Your e-mail log will automatically be acknowledged by the server and entrants will be informed about process of log-checking. Before sending, please check if your log contain all necessary data (especially sent and received exchange), be sure to put used callsign in the "Subject:" line of each message and name the files by used callsign.
    6. Log Deadline: All log entries must be postmarked by December 1st.
  12. Penalties: For QSO errors (broken calls, bad exchanges) and QSOs which do not appear in correspondents log. One times the QSO points for such QSOs will be deducted (except errors in exchange). 10% or more bad contacts or violation of contest rules shall result in dropping the participant from the classification.
  13. Disqualification: Violation of contest rules, unsportsmanlike conduct or taking credit for excessive unverifiable QSOs will be deemed sufficient cause for disqualification.
  14. All decisions of the contest committee are final. The contest is sponsored by Czech Radio Club (CRC), member of the IARU.
  15. Awards: The participants will be awarded in three divisions: OK/OM, EU and DX. In each division and each category the top 50% of entrants will be awarded. From all entrants will be allotted 10 entrants (random selection) who will get T-shirt with contest logo. Plaques will be awarded to the winners of the categories, only if they make at least 73 QSO in single band category, 200 QSO in QRP or 400 QSO in all band category. One station can be awarded up to one plaque - for the category, where the maximum of points were achieved. The list of awards and their donors is still updating (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: "okomdxc at crk.cz").
