    4. Entrants and Sections

    This contest is primarily intended for RSGB Members and Affiliated Societies

    Non-Members may only enter as part of an Affiliated Society multi-operator team, or if they are entering as a single operator on behalf of an Affiliated Society and they are using the club callsign. 

    Non-UK teams or individuals may also enter.

    Definition: Single Operator - a station operated by a single person, with no operational assistance of another person or persons during the contest period. 

    Definition: Assisted - an operator is using support in order to locate and identify callsigns. Examples are the DX Cluster, RBN, local or remote multi-channel decoder such as CW Skimmer, internet spotting applications, receiving an SMS from another person on the whereabouts of stations, etc.

    Definition: Unassisted - an operator is locating and identifying every callsign that they put in their log, where locating means to tune into each signal. (this is the opposite of "Assisted" above). The operator may not use any outside tools such as the DX Cluster or RBN network to locate new contacts, neither may they use any local decoder which will identify signals other than on the frequency to which they are tuned.

    QRP Unassisted Portable: Single transceiver, 5W max. One single antenna (vertical, dipole or loop) comprising a single element with traps and/or removable links - maximum of two elevated supports not exceeding 15m above ground. Receiving with more than two receivers or receiving while transmitting is not allowed.

    QRP Get on the Air, Renewable Energy, Unassisted Portable: Single Operator, Single transceiver, 5W max. Total operating time is a maximum of 6 hours; off-periods, if taken, must be at least 60 minutes. One single antenna (vertical, dipole or loop) comprising a single element with traps and/or removable links - maximum of two elevated supports not exceeding 15m above ground. Power must be from batteries or a renewable energy source.

    Low Power Unassisted Portable: Single transceiver, 100W max. One single antenna (vertical, dipole or loop) comprising a single element with traps and/or removable links - maximum of two elevated supports not exceeding 15m above ground. Receiving with more than two receivers or receiving while transmitting is not allowed.

    CW FD Only - Low Power Assisted Portable: 100W max. No restriction on equipment, aerials or assistance.

    SSB FD Only - High Power Assisted Portable: Maximum licensed power. No restriction on equipment, aerials or assistance.

    Fixed: No restriction on equipment, power, aerials or assistance. Fixed stations may only work Portable stations for QSO points, but can work any stations for DXCC multipliers. Fixed Stations must be Single Operator entries i.e. the same operator for the duration of the contest. Fixed Stations that list more than one operator will be reclassified as a Check Log.

    Operation must be from a single Station location where all transmitters, receivers, and antennas are located within a circle of a radius no greater than 500m

    Remote receivers outside the Station location are not permitted

    Remote operation of a Fixed station is allowed where the operator is situated within the same country on the DXCC list. Additionally an operator's home station, as shown in the licensee's licence documents, may be remotely operated from a location in another country.

    A remotely operated station must obey all station licence, operator licence, and category conditions. The callsign used must be one issued or permitted by the Regulatory Authority of the remote station location.

    The address of the operator must be included in the 'Address of Operator when operating Remote from Station Address' box on the Station Information Page and the address of the remote station must be included in the Cabrillo header 'ADDRESS:' box.

    The RSGB HF Contest Committee may place remotely operated stations in a separate results table.

    In the Unassisted sections, the following are not permitted: public internet based assistance such as RBN, DX Cluster or private off-site assistance, and also local/on-site Skimmers

    Special Contest Callsigns or Club Callsigns may be used. GB callsigns and other 'special event' prefixes (e.g. GR) must not be used.

    All Portable stations must sign /P

    For portable stations, the installation of the station and antennas must not start earlier than 48 hours before the beginning of the contest

    Portable stations must be powered by on-site generators or batteries or renewable energy source and must not be set up in a permanent building or structure

    The use of existing or previously installed equipment is not allowed


    5. Exchange RS(T) plus Serial Number starting at 1 and incrementing by 1, irrespective of band; entrants will not be penalised if their sent serial numbers are logged slightly out of sequence

    Please log any exchange that you are sent to the best capability of your logging facility; if you are not sent an exchange, log a zero

    6. Scoring Portable station Sections :
            Portable and Mobile stations in Europe (including UK&CD): 4 points per valid QSO
            Portable and Mobile stations outside Europe: 6 points per valid QSO
            Fixed stations in Europe (including UK&CD): 2 points per valid QSO
            Fixed stations outside Europe: 3 points per valid QSO

    Fixed station Section :
            Portable and Mobile stations in Europe (including UK&CD) : 4 points per valid QSO
            Portable and Mobile stations outside Europe : 6 points per valid QSO

    For all Sections in CW Field Day, contacts on 160m score double points

    Fixed stations may only work Portable stations for QSO points, but can work any stations for DXCC multipliers

    Multipliers:
            DXCC entities per band. The final score is the total of QSO points multiplied by the total DXCC entities.

    7. Log Submission
            and Adjudication
    Submit in Cabrillo format here within 5 days of the end of the contest. View the correct Cabrillo format for this contest.

    Single Operator Portable entrants should indicate that they were Single-op when uploading their log

    If the robot finds format errors, it will reject the log and ask for resubmission of a corrected logfile

    Second and subsequent log uploads may be subject to analysis of any changes that have been made

    If you have difficulties preparing or uploading your Cabrillo logfile, please contact the contest adjudicator (see section 11 below) to ask for assistance, before the submission deadline

    Adjudicated results will be online and will include online logfiles for all entrants

    Errors will incur penalties as outlined in the RSGB HF Adjudication Principles. This penalty will be the loss of an additional 2 QSO points.

    The use of CAT Control to log the correct frequency and mode is highly recommended - you will lose QSO points for frequency and mode errors

    At the present time, it is not possible to automatically enter logs into the Region 1 (DARC) Field Day Contests. If you wish to also enter the Region 1 Field Day Contests, please submit your log for the Region 1 CW Field Day Contest here and for the Region 1 SSB Field Day Contest here. The rules for the Region 1 Field Days are available here.

    8. Results and Awards

    There will be separate tables of results for UK&CD entrants and a combined table for non-UK&CD entrants.

    Awards for RSGB HF Contests are shown here. The trophies for these contests are for UK&CD entrants.

    Winners of awards, section winners and the highest scores on each band will be indicated in the results tables complete with downloadable certificates. 

    A certificate may also be downloaded by all entrants showing their position in their entry section.


    9. Supplementary Rules (a)  All portable stations may be inspected by a representative of the HFCC or CSC, both before and/or during the contest

    (b) Site location and access details must be provided before the start of the contest if requested by a representative of the HFCC. Failure to provide the information may result in the entry being reclassified as a Checklog.

    (b)  Any infringement considered to be outside the spirit of the contest may result in QSOs being disallowed, the entry being reclassified as a Checklog, or the entry being disqualified

    (c)  Self-spotting or asking to be spotted is not permitted

    (d)  Call signs logged must be the same as those exchanged over the air by the entrants during the QSO. Correction of logged call signs and exchanges after the contest, by use of any database, recordings, email or other methods, is not allowed.

    (e)  All requests for contacts, responses to calls, and copying of call signs and contest exchanges must be accomplished during the contest period using the mode and frequencies of the contest

    (f)  You must send your callsign at least every 3rd QSO and no less often than once a minute

    (g)  Proof of contact e.g. an MP3 audio recording, may be required as part of the adjudication process

    (h) UK&CD entrants are required to use a Regional Secondary Locator (RSL) where it is necessary to clarify the entity from which they are operating. From 21 February 2024, stations operating from England may optionally use the RSL “E”. If no RSL is used e.g. M0HDG, G6XX or GB4ABC, the station will be assumed to be in England. The use of a misleading RSL will disqualify the entry.

    (i) UK&CD entrants may append their call sign with one of the following: /A (Alternative Address), /P (Temporary Location), /M (Mobile) or /MM (Maritime Mobile) and this will comprise part of the call with which they enter. Other suffixes used by UK&CD stations, whether or not they are entrants, will be removed in adjudication and need not be logged.

    10. Declaration By entering any RSGB HF Contest you declare that:
    (a)  Your station was operated strictly in accordance with the rules and spirit of the contest, within the conditions of your licence, and that the power output from your transmitter was no greater than that permitted in the section of the contest that you are entering.
    (b)  You agree that decisions of the RSGB HF Contest Committee will be final in cases of dispute.
    (c)  By submitting a log entry, entrants give the RSGB permission to score, amend, publish, republish, print, and otherwise distribute that entry by any means.
