    RSGB CW National Field Day

    Main rule change for 2016 -- Log deadline is now 7 days.

    This is an excellent club activity with varied areas of expertise required, such as antenna design, construction and erection, generator maintenance and, increasingly, computer expertise. Give your CW operators some support!

    The QRP Section is limited to 12 hours of operation. This should assist groups who have difficulty in finding operators to cover the full 24 hours.

    Pre-registration for Field Day is not an absolute requirement, but clubs are encouraged to do so, in order to qualify for awards.

    A list of Frequently Asked Questions and answers, with associated diagrams, is available.


    1. Basic Information

    The General Rules apply to this contest except where superseded by the rules below

    Date: 4 - 5 June 2016 (the first full weekend in June).

    Time: 15:00 – 15:00 UTC

    Bands: 1.8, 3.5, 7, 14, 21 & 28MHz.

    Mode: CW

    Exchange: RST + Serial number.

    Special Contest Call Signs (SCC) are not permitted in this contest, even for entrants who hold a valid NoV from OFCOM.

    2. Registration

    a)   In order that inspections can be arranged, each group intending to compete must provide, by no later than 8 May 2016, details of the site to be used. Registration is performed on-line at http://www.rsgbcc.org/cgi-bin/nfdregister.pl. Details must include:
         
    • the name and address of the person responsible for the entry
    • Section to be entered
    • name of group
    • callsign to be used
    • National Grid Reference (eg. SX 690804)
    • sufficient access information to enable an inspector to locate the site
    b)   All stations are subject to inspection by representatives of the RSGB Contest Committee, whose brief will be to ensure that the rules and spirit of the contest are being observed. The inspector must be given immediate access to the site and may make return visits. To allow an inspector to find a new site in the event of a late change, the adjudicator will email registered entrants before the contest with a telephone number which can be used to notify the changed QTH and access details. Groups not registering may take part in Field Day but will not be eligible for awards.

    c)   A list of entrants who have registered may be seen here.


    3. Site

    The following rules apply to the site used:

    a)   The Site is defined as the place within which all equipment comprising the station (including tents, generators, aerials and supports, etc.) is situated. It is defined to be circle of 500m radius, centred on the location of the transmitter(s).
    b)   Entrants must operate from the same site for the whole contest.
    c)   Stations must not be located in a permanent building or shelter

    Paragraph 4a lists rules that apply to all Sections. Paragraphs 4b - 4d list rules that are Section specific.

     

      4(a) All Sections
      i)   Multi operator operation is permitted in all Sections, but some variations are made to this term as defined in the HF General Rules.
      ii)   The rules in paragraph 4 assume the use of transceivers rather than separate receivers and transmitters. However use of separates is permitted – entrants intending to use them should contact the Contest Committee for guidance on interpretation of the rig rules
      iii)   CW Skimmer-like technology (eg. MixW) is permitted as a CW reader to allow non-CW literate operators to participate, subject to the following:
           
    • No separate receiver for the CW reader is permitted (i.e. the CW reader must be driven from a permitted transceiver)
    • A maximum receiver bandwidth of 3kHz is permitted, which must be the same frequency range that the operator can hear. There must be no connection between the CW reader and the contest logging software: callsigns and serial numbers must still be typed in by hand
         
     
         
     
      4(b) Open Section
      i)   Operation for the full 24 hours is permitted
      ii)   A maximum power of 100W at the output of the transmitter(s) is permitted
      iii)   A maximum of 2 transceivers is permitted, but only one signal may be radiated at a time
      iv)   Use of on-site CW Skimmer as an aid to seeking QSOs is permitted, and a dedicated receiver in addition to the permitted transceivers may be used for this purpose. This is distinct from the use of Skimmer-like technology as an aid for non-CW literate operators, as set out in 4(a)(iii)
      v)   Use of public internet based assistance such as RBN or DX Cluster is permitted. Private off-site assistance is prohibited by rule 3(a)
      vi)   Antennas are subject to rule 3 above, otherwise there is no restriction on the number and type of antennas or supports, except that the maximum height of any support or part of any antenna must not exceed 22m.
         
     
         
     
      4(c) Restricted Section
      i)   Operation for the full 24 hours is permitted
      ii)   A maximum power of 100W at the output of the transmitter(s) is permitted
      iii)   In the Restricted - Complex Category, a maximum of 2 transceivers is permitted, but only one signal may be radiated at a time.
    In the Restricted - Simple Category, only a single transmitter is permitted
      iv)   In the Restricted - Complex Category, use of on-site CW Skimmer as an aid to seeking QSOs is permitted, and a dedicated receiver in addition to the permitted transceivers may be used for this purpose. This is distinct from the use of Skimmer-like technology as an aid for non-CW literate operators, as set out in 4(a)(iii).
    In the Restricted - Simple Category, use of on-site CW Skimmer as an aid to seeking QSOs is not permitted, However, the use of Skimmer-like technology as an aid for non-CW literate operators, as set out in 4(a)(iii) is permitted
      v)   Use of public internet based assistance such as RBN or DX Cluster is not permitted. Private off-site assistance is prohibited by rule 3(a)
      vi)   Beam antennas are not permitted
      vii)   In the Restricted - Complex Category, with the exception of beam antennas which are not permitted, there is no restriction on the type or number of antennas, subject to the following:
         
    • an overall antenna length allowance of 120m of wire, out of which all antennas used during the contest must be made
    • the wire used must be of a diameter not exceeding 14swg or equivalent (excluding insulation). However where masts, towers or trap verticals are used as antenna elements, this diameter restriction does not apply.
      viii)   In the Restricted - Simple Category, only one antenna is permitted. This must be a single element with a length no greater than 120m: note that traps and stubs are permitted, but a "fan of dipoles" is not permitted.
      ix)   In the Restricted - Complex Category, there is no restriction on the number of antenna supports, subject to a maximum antenna support allowance of 22m. An entrant's antenna support usage (ie. the amount of antenna support actually deployed within the 22m allowance) is the sum of the individual contributions from all masts, towers and trees used to support antennas.
      x)   In the Restricted - Simple Category, no more than two elevated supports are permitted, and may not exceed 11m above ground at the highest point
      xi)   Use of buildings as supports is already forbidden by 3(d)
      xii)   Strings and halyards are not included in the antenna support usage.
         
     
      Further information on the way in which the above items contribute to the antenna support usage is given on the FAQ page.
         
     
         
     
      4(d) QRP Section
      i)   Operating is permitted for a maximum of 12 hours. Off-periods must be a minimum of one hour and should be listed on the summary sheet or soapbox lines of the Cabrillo header
      ii)   A maximum power of 5W at the output of the transmitter is permitted
      iii)   A single transceiver is permitted
      iv)   With the exception of aid for non CW literate operators as set out in 4a above, use of on-site CW skimmer is not permitted
      v)   Use of public internet based assistance such as RBN or DX Cluster is not permitted. Private off-site assistance is prohibited by rule 3(a)
      vi)   Only one antenna is permitted. This must be a single element with a length no greater than 120m, having not more than two elevated supports and not exceeding 11m above ground at its highest point. Note that traps & stubs are permitted but a “fan of dipoles” is not.
