that could affect their submitted score.
c. Only one transmitted signal is allowed at any time. Only one operator is allowed to perform all of
the operating and logging functions and only one callsign is allowed from a particular radio station.
d. When two or more transmitters are present on the same band, a hardware device must be used to
prevent more than one signal at any one time. It is not permitted to request or solicit QSOs (e.g.,
call CQ) on more than one frequency on the same band at a time. The second interlocked station

EUROPEAN HF CHAMPIONSHIP RULES
f. Remote operation is permitted if the physical location of all transmitters, receivers, and antennas
are within a 500-meter diameter circle. A remotely operated station must obey station license,
operator license and category limitations. The callsign used must be one issued or permitted by the
Regulatory Authority of the station location. Remote receivers outside of the station location are
not permitted.
g. Any public QSO alerting assistance is allowed for all categories. This includes, but is not limited to,
DX Cluster-type networks, local or remote Skimmer and/or Skimmer-like technology and reverse
beacon network.
h. Self-spotting or asking to be spotted is not permitted.
i. Logs with contacts only on one mode in categories #1 – 6 will be classified as “single mode” (CW or
SSB) entries.
Additional Terms of Competition for categories #7 and #8
SINGLE-OP-UNLIMITED
SINGLE-OP-UNLIMITED category is subject to the same rules as existing High Power Categories (# 1, 3,
5), except that there is no limit to the maximum number of band / mode changes and audio
recording of the contest is required (see more detailed explanation below).
SINGLE-OP-UNLIMITED has only “All Band Mixed” classification, there is no separate division related to
the “Mode” or “Power”.
Audio Recordings requirement
SINGLE-OP-UNLIMITED entrant competing for a top five (5) finish:
- must record the transmitted and received audio as heard by the operator for the duration of the
contest operation - the recording must be in a common format (e.g., mp3, wav…) and should include the audio to each
ear as a separate channel. - the recording must be a continuous recording (not a recording of individual QSOs), dividing files by
individual hours is allowed, where each recording must not be shorter than 1 hour - time “off the air” (when not transmitting or receiving) does not have to be recorded
- the recording may be requested by the Committee within 90 days after the log deadline to help
adjudicate the log - the recording files must be provided by the entrant within 5 days of the request
- failure to submit a requested audio recording within the deadline will result in the reclassification
of a log entry to Checklog or disqualification in case of identified violations as described in point
14.a below
SINGLE-OP QRP
SINGLE-OP QRP category is subject to the same rules as category # 2 (Mixed LP), except total output
power must not exceed 5 watts at any time. A maximum of ten (10) band and mode changesrestriction
applies (see paragraph 9).
- CONTEST EXCHANGE
SSB: RS report / CW: RST report + two-digit number of the Year of Operator’s first ever official amateur
radio license irrespective from which station operation takes place or which callsign is used in the
contest.

EUROPEAN HF CHAMPIONSHIP RULES
NOTE:
- 59(9) 82 means that first ever official amateur radio license was issued in 1982, 17 means 2017 etc.
- official SWL license also counts as first official amateur radio license
- there is no exception regarding use of Club call, Special Event or Contest calls, exactly the same
rules apply as written above, operator’s first ever official license counts as valid exchange - please contact the organizer before the contest if you are unsure or in doubt about the correct
contest exchange
- MULTIPLIERS
Multipliers are different two-digit numbers, meaning the last two digits of the year of operator’s first
ever official amateur radio license. The multiplier is counted only once per band regardless of mode. - QSO POINTS
Each completed valid contact counts one (1) point regardless of mode. The same station may be
contacted once per band and mode. - SCORING
The final score is the result of the total QSO points multiplied by the total number of multipliers. - BAND AND MODE CHANGES – applicable for all categories except SINGLE-OP-UNLIMITED (#7)
a. Mixed mode categories (category #1, 2, 8) – a maximum of ten (10) Band and Mode changes may
be made in any clock hour (00 through 59 minutes). For example, five (5) band plus five (5) mode
changes, where band together with mode change counts as one (1) change.
b. Single mode (CW or SSB only) categories (category #3, 4, 5, 6) – a maximum of ten (10) Band
changes may be made in any clock hour (00 through 59 minutes).
c. Important: Band or mode change in the transition from one full hour to another is counted as
the 1st change in the next full hour. Example: QSO at 13:59 on 20CW, next QSO 14:00 on 10CW
already counts as 1st change in 14:00 – 14:59.
d. Any band or mode change after 10th band / mode changes will be penalized with QSO points and
mults deduction for those QSOs in particular hour. - DXCC ENTITY COMPETITION
A separate list of valid DXCC entity scores (the sum of all scores from valid DXCC country), regardless of
club affiliation, will be published. Latest ARRL DXCC Current Entities List is used for this purpose. - AWARDS (Plaques & Certificates)
a. Plaques will be awarded to the EU Champions in a number of categories depending on sponsorship
b. It is strongly recommended to write exact operating frequency for each QSO in the Cabrillo log.
Only logs with exact written frequencies will be eligible for the plaques
Note: If you do not use a CAT control to log the exact frequency of the QSO, please enter only the
generic frequency (1800, 3500, 7000, etc.) in your Cabrillo and please do not use other artificial
frequencies within the band (3545, 7033 and similar).
c. Logs submitted after the deadline may be listed in the results, but are not eligible for plaques.
Resubmitting an entry after the deadline will result in it being considered as a late log.
d. Electronic certificates will be made available for download for everyone that submits an entry.
