c. Categories:

SOAB-MIX-HP – Single Op, All Bands, MIXED,

SOAB-MIX-LP – Single Op, all bands, MIXED, low power (do 100 W)

SOAB-MIX-QRP – Single Op, all bands, MIXED, QRP (do 5 W)

SOAB-CW-HP – Single Op, all bands, CW

SOAB-CW-LP – Single Op, all bands, CW, low power (do 100 W)

SOAB-SSB-HP – Single Op, all bands, SSB

SOAB-SSB-LP – Single Op, all bands, SSB, low power (do 100 W)

SOSB – Single Op, single band, MIXED (6 different bands, separately 160, 80, 40, 20, 15, 10 m)

MOST – Multi Op, all bands, one transmitter, MIXED

M/M – Multi Op, more transmitters, MIXED

Multi-Transmitter Distributed (MULTI-DISTRIBUTED) (*)


(*) category Multi-Transmitter Distributed (multiple distributed transmitter).

Stations operating in this category may have a maximum of six broadcast signals at any given time, one per band, from stations in different places.

All devices, including remote controlled devices, must be located:

– in the same region for European Union countries (see the rules, that 7);

– in the same DXCC and in the same ITU zone for countries outside the European Union.

d. For single operator categories, only one signal is allowed at any time. Using a DX cluster, skimmers or any other auxiliary system is permitted for all participants. Self-spottin or requesting other stations, to spot you, is not allowed.

e. Duplicate CQ on the same band is prohibited.

f. For stations with multiple Multi-TX operators, only one broadcast signal is allowed on each band.

g. Bands: from 10 m do 160 m, except for the WARC bands, are allowed under the IARU band plans.

3. Body za QSO

a. Stations of the European Union:

QSO with own country – 2 body,

QSO with another European Union country – 10 points,

QSO with a non-European Union country on your continent – 3 body,

QSO with another continent – 5 points.

b. Stations outside the European Union:

QSO with European Union stations – 10 points,

QSO with own country – 2 body,

QSO with another country of your continent – 3 body,

QSO with another continent – 5 points.

4. Code exchanged

– European Union stations will broadcast RST and a two-letter and two-number code to identify their regions (see point 7).

– Other stations will transmit RST and ITU zone.

5. Multipliers

– Region of the European Union: multiplier value of one (1) for every other region of the European Union, with which you will connect on every band;

– This is the best score of a station in a given area in a given category: (1) for each country, which was realized connection in each band. List of DXCC entities, list of Worked All Europe multipliers (WAE) plus IG9/IH9 and continent borders are standards for defining country multipliers.

Example: the first QSO with an EU station on the competition band will have the value of both the country and region multiplier.

6. Final score

All stations: The final score is the result of the sum of the QSO points multiplied by the sum of the EUR multipliers (regions of the European Union) and countries.

The order of European Union stations and DX stations will be listed separately.

7. Regions of the European Union (by region of the country):

(1) DK06 Overseas Countries and Territories

(2) FR20 Overseas France
French Polynesia
New Caledonia
Wallis and Futuna
Saint Barthelemy
Saint Pierre and Miquelon
French Southern and Antarctic Lands

(3) NL13 Overseas Countries and Territories
St Martin
but in the contest log such DX stations will definitely be requested & St. Eustatius

8. Duplicate connections

Duplicate connections are connections to the same station in the same band and mode. Duplicate connections have value 0 points.

9. QSO

You can follow up to the maximum 2 QSO with the same station on the same band – CW a SSB. CW QSOs must be made in the CW portion of the band, but only the first QSO is valid for a multiplying point in a given band.

10. General note

– All transmitters and receivers must be placed in a circle with a maximum radius 500 m. All antennas used by each participant must be physically connected by cables to the transmitters and receivers.

– Remote operation is allowed, if the physical location of all transmitters, receivers and antennas at one location of the station. (e.g.: If an EU station has a remote station in the Bahamas and is working with its EU call sign – it is not allowed. If a station from the EU has a remote station in the Bahamas and uses the call sign C6 – it is legally remote).
– The use of WEB Clusters and packet radio systems is permitted for all participants.
– Using transmitters and receivers from different locations connected via the Internet is considered unsportsmanlike and is one of the reasons for disqualification.
– Self-spotting on clusters is not allowed.
– Requesting a QSO by phone, telegramov, the Internet, radio packet during the competition is considered selfspotting and is not allowed, leading to disqualification.
– Participants in the Single Operator category can change bands and operating modes without restriction. However, it can be at the same time “in the air” only one single signal.
– MOST stations must comply “the rule 10 minutes”. The time spent on one band starts counting from the moment, when the first QSO is made in that band. It can be at the same time “in the air” only one single signal.

11. Definitions

– Single Operator: are those stations, in which one person is in charge of these duties: obsluhu radiostanice, recording QSOs and spotting. There is no limited operating time or band changes.
– All MIXT categories can work with the same station in both CW and SSB. QSO connections in CW within the SSB band segments and vice versa are prohibited.
– preliminary results: Only one broadcast signal is allowed on one band during any 10-minute period (starting a station/signal). Exception: Work station is a new multiplier. The run and multiplier transmitters follow independent 10-minute rules.
– Multi-Multi: Six competition bands can be activated simultaneously. Only one broadcast signal is allowed in each band at any time.

12. Diaries

– Diaries are only accepted in CABRILLO electronic format 3.0
– Participants, who strive for placement in the top three in any of the categories mentioned in the point 2, are required to record the exact frequency of each QSO made in the logbook (using the CAT system), while the minimum unit must be 1 kHz. Placement in the Top 3 participation in any of the categories will be confirmed only under the condition of stating the exact frequency of each QSO in the log, or by making the audio recording from the period of participation in the competition available to the referee.
– Checklogs are accepted.

13. Sending logs

– All logos must be sent to the competition organizers no later than 7 (seven) days after the end of the competition. (No later than 2023-02-12 12:00:00)
– Each Log will be confirmed by e-mail, as well as placing in “List of received Logos” on the said website.

14. Awards

– Diplomas and plaques will be awarded for the first places in each category mentioned in point 2.c. An electronic PDF diploma will be awarded to all participants.

15. Sanctions and disqualifications

– Logs will be checked carefully by the Competition Committee and errors may result in points being deducted. There are no penalties for erroneous QSOs, but unsportsmanlike conduct may result in disqualification. Unsportsmanlike conduct can be detected in LOG data, as well as in any other recording media, available to the commission.
– All decisions of the competition committee are official and final.
