- 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
- 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
- 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.
RSGB CW National Field Day 2013
Please read carefully. Although based on the 2012 rules, there are a number
of changes resulting from responses to the questionnaire issued
in autumn 2012.
Since these rules were originally published in February 2013, a minor modification has been made to rule 4 c (viii) and to some of the associated diagrams. This has been done to ensure consistency with FAQs and associated diagrams, and does not change the intent of the rules.
To explain some of the changes, a list of Frequently Asked Questions and answers, with associated diagrams, has been compiled.
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 Low Power 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.

2. Registration
| a) | In order that inspections can be arranged, each group intending to compete must send details of the site to be used to nfd.notify@rsgbcc.org or to Quin Collier G3WRR (QTHR), to arrive no later than 12 May 2013. Details must include: | ||
|
|
|||
| b) | In the event of a late change of site, it is the responsibility of the members of the group to make suitable arrangements for the inspector to find the new site. Groups not registering may take part in Field Day but will not be eligible for awards. 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. | ||
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 | |
| d) | No permanent building or structure may be used as an aerial support (trees are acceptable). | |
| e) | Power must be obtained solely from on-site batteries, portable generators or solar cells, without use of public mains | |
| f) | All equipment directly associated with operating in the contest (including radios, tents/caravans, generators, aerials and supports, etc.) must be set up on site no more than 24 hours before the start of the contest | |
| g) | Equipment may be stored on site outside this 24 hour period. However all equipment directly associated with operating in the contest that is on the site more than 32 hours before the start of the contest must be removed beyond the boundary of the site and brought back on within a period of not more than 32 hours before the start of the contest. | |
| h) | Equipment such as caravans & towers permanently resident on site that are to be directly associated with operating in the contest must be removed & returned as set out in 3(g) above | |
| i) | Entrants who may have difficulty in complying with the requirements of 3(g) and 3(h), for reasons such as physical infirmity, should consult the Contest Committee | |
| j) | All portable stations are required to sign /P when taking part in this contest notwithstanding the licence regulations making the use of the /P suffix optional |

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: | |||
|
|
||||
| 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 | ||||
|
Results in the Restricted section will be tabulated, as usual, in points order. However, individual entries will be annotated to provide information about the antenna(s) used. Entrants compliant with the antenna requirements of the Low Power section but otherwise in accordance with the Restricted Section rules will have their entries annotated SIMPLE ANTENNA: those using antennas compliant with the requirements of the Restricted section but exceeding what is permitted in the Low Power section will have their entries annotated COMPLEX ANTENNA. (When submitting their logs, entrants will be prompted by the robot to enter SIMPLE ANTENNA or COMPLEX ANTENNA category as appropriate). |
