- QRP Power: Total output power must not exceed 5 W on any band at any time.



6. Each entrant undertakes to abide by the rules of this notice, the provisions applicable to her/him by the authorities of her/his own country and to accept the decisions of the Competition Committee.



7. Entry Categories:

Single operator (SO):

-       One person performs all operating and logging functions.

-       Use of spotting nets, packet, or multi-channel decoders (such as CW Skimmer, RBN) is permitted.

-       All operators must observe the amateur radio regulations of their respective countries at all times.

-       Single operator stations are allowed only one transmitted signal at any given time.


7.1. Single Operator, All Band (SOAB)

7.1.1. SOABH- High output power level

7.1.2. SOABL- Low output power level

7.1.3. SOABQ- QRP output power level


7.2. Single Operator, Single Band (SOSB) – No separated output power level categories

The SOSB participant can enter in a maximum of two different single band categories. This allows a station, for example to enter log for 10m and 160m with both eligible for awards. This option must be selected by the operator during LOG upload. Only one log must contains all contacts.

Single Band entrants operating other bands during the contest are encouraged to submit check logs for their other bands to aid in the log cross-checking process.


7.3. Multi Operator, Single Transmitter (MOST)

7.3.1. MOSTH- High power level

7.3.2. MOSTL- Low power level


Must remain on a band for at least 10 minutes before changing bands. The “10 minute clock” starts when a first QSO is logged (Run station). The run station minimum time to stay on a band is 10 minutes. A quick band change in order to work a new multiplier is allowed – so it is OK to work one new multiplier station and return to the main band. Alternating CQs on two or more frequencies is not permitted.

All operators must observe the amateur radio regulations (e.g. power limits) of their respective countries at all times.Violation of the band change rules will reclassify the entry as a checklog.

7.4. Multi Operator-Multi Transmitter (MOMT)-No separated output power level categories

The six contest bands may be activated simultaneously. Only one transmitted signal per band is permitted at any time. Violation of the band rules will reclassify the entry as a checklog.




7.5. For Tisza riverside countries (Ukraine, Romania, Slovakia, Hungary, Serbia)

The same rules and categories as SOAB, SOSB, MOST and MOMT

9.4. Cross mode, cross band and repeater contacts are not valid QSOs.

A station winning a plaque will not be considered for a sub-area award; the plaque will be awarded to the runner-up in that area.


C. Special Awards: The two Radio Clubs in Debrecen and the Council of Debrecen city also established a special award. The individual participants (single op, both Tisza riverside and other categories) with the highest points will be invited to spend the Carnival week (with his/her partner) in Debrecen city. The Flower Carnival of Debrecen city (20th of August, every year) and the related cultural and entertainment programs are famous far and wide. The special award includes the cost of weekly accommodation, meals and VIP entrance fees.

15. Others:

All the radios and antennas must be in physical contact with each other and within 500 meters radius.

Under the above mentioned conditions, remote operation is allowed.

Contacts that violate the 10-minute rule should not be deleted from the log, but marked with an X-QSO in the Cabrillo log. Contacts marked with the X-QSO do not result in penalty points.

Do not delete dupe contacts! If there is a valid contact to a station in the same band, it will be scored. It counts as zero (0) points without penalty point even if the received exchange is incorrect or the contact is not included in the other station's log.

For logged contacts, the time difference between the 2 stations's log records may not exceed 3 minutes. Exceeding that, the contact will be deleted. This does not authorize anyone to establish a contact outside of the contest period. It is advisable to synchronize your computer clock with your GPS or Internet time server before the contest.

The callsign of a multiplier, if no log has been submitted from them, must be included in the logs of at least 5 other competitors. Otherwise the multiplier contact will be deleted.

Clarification for SWLs:
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: This email address is being protected from spambots. You need JavaScript enabled to view it.

SWL LOGs are not accepted through the web. Each QSO record must contain: date, UTC, band-frequency, callsign of the station, sent code, callsign of the corresponding station, points, new multiplier, SWL call.    

The summary should be part of the LOG and should contain: for each band number of QSOs, points, multipliers. The LOG should contain the receiver information and e-mail.

Disqualification: Violation of contest rules, unsportsmanlike conduct or taking credit for excessive unverifiable QSOs will be deemed sufficient cause for disqualification.

  • All decisionsof the contest committee are final.

The contest is sponsored by the organizers.
