(March 2, 2001 Revision)
Because no official rules exist for IARU Region 2, The 2001 United States ARDF championships in Albuquerque New Mexico used this set of interim rules:
These rules are for use at the US National ARDF Championships in 2001.
These rules are designed to support the development and growth of the sport of ARDF. When equipment and resources are not always available to meet the exact letter of the rules, event organizers may modify the details to suite the circumstances, while maintaining the spirit of the rules. Significant rule modifications shall be communicated to participants before the event.
Competition for National Championship awards is open to all foxhunters from the hosting nation. Foxhunters from all other countries are invited to participate and compete for Visitors' awards.
The age categories are as follows:
|Women (D)||Men (M)||Age|
|D19||M19||19 and younger|
|D21||M21||Regardless of age|
|D35||M40||35/40 and older|
|D50||M50||50 and older|
|---||M60||60 and older|
Competitors belong to the M19 or D19 category up to the end of the calendar year in which they reach the age of 19.
Men competitors aged 40 or older or women competitors aged 35 or older belong to each category from the beginning of the calendar year in which they reach the given age.
At the discretion of the hosting organization, divisions may be combined whenever the total number of persons in two adjacent age divisions is less than those in other divisions. If so, it should be announced in advance if possible.
The participation fee for championship events will be set by the host society.
All participants in National Championships shall be responsible for their own travel expenses, accommodations, board and entry fees.
Administrative and technical expenses connected with the Championships shall be borne by the host society.
The jury shall be selected by the organizers. Jurors shall be of good character and shall understand the rules of the competition.
The Jury shall consist of :
- Chairman of the Jury
- Secretary of the Jury
- Referee at the start
- Referee at the finish
- Referees in the competition area
- Siting referee
- Technical director
Section 9 of the new proposed region 1 rules V2.3A serve as a model for the operation of the jury
Decisions of the jury are final and cannot be challenged.
RDF Championships shall take place on two amateur bands, namely 3.5 MHz and 144 MHz.
ach participant may take part in competitions on both 3.5 and 144 MHz or in competition on only one band.
It is absolutely forbidden to give or take any assistance from or to any person, including competitors, and also to utilize any means or method of transport. The penalty for both shall be disqualification. However competitors are expected to provide emergency assistance or first aid to another competitor when needed: no competitor will be disqualified for providing such assistance so long as they gain no competitive advantage by doing so.
the use of GPS receivers for navigation is not allowed. It is considered receiving assistance.
Competitors shall not inflict loss or damage on or to the property of any other person.
Competitors take part in all competitions at their own risk. All Competitors will be required to sign a waiver form.
T he safety of the participants shall be a prime consideration in choosing a site for an event.
Each course will have at least 5 transmitters. Minimum distance between transmitters is 400m, and the transmitter closest to the starting point should be at least 750m away. Total course length from start to finish, via all transmitters, should be between 4 and 7 km.
In the event of a thunderstorm, the Chairman of the international Jury is entitled to recall the competition immediately.
Each transmitter will be marked with a marker or flag within 2 meters. Although the standard red and white triangular prism is recommended, any unique, brightly colored marker is acceptable. All prisms must be identical, and a sample must be displayed at the starting point. The transmitter number shall be marked on the prism.
Transmitters must be operated within the regulations of the country where the event is taking place. Frequencies shall be chosen in accordance with the local band plan.
Antenna patterns will be omnidirectional in the horizontal plane. Vertical polarization will be used on 80 meters. Horizontal polarization will be used on 2 meters.
The standard MOE/MOI/MOS/MOH/MO5 sequence will be used. A finish line beacon sending MO on a different frequency will be used for both the 80-meter and 2 meter hunts.
(80 Meter band)
(2 meter band)
Power Level: Output power shall be between 1 - 5 Watts.
Modulation: CW (A1A) will be used.
Antenna: Vertical wire with radials
Power level: Output power shall be between 0.25 - 3 Watts.
Modulation: MCW F2A. Peak frequency deviation shall be between +/- 2 to 3.5 KHz, continuous carrier.
Antenna: Omnidirectional horizontal (turnstyle)
Note: The international standard is AM modulation with the carrier keyed, but it is much easier with commonly available equipment to generate FM signals on a continuous carrier in region 2.
Transmitters shall be searched by each category as follows.
- M21 category shall search all five transmitters
- M19 category shall not be scored for transmitter number 3 (MOS)
- M40 category shall not be scored for transmitter number 5 (MO5)
- M50 category shall not be scored for transmitter number 2 (MOI)
- D19 category shall not be scored for transmitter number 2 (MOI)
- D21 category shall not be scored for transmitter number 4 (MOH)
- D35 category shall not be scored for transmitter number 1 (MOE)
- D50 and M60 shall not be scored for transmitter number #4 (MOH) and # 1 (MOE)
The competitors control card will have the transmitters not scored mark out with a large "X".
D. RULES FOR COMPETITORS
E ach competitor shall provide her or his own equipment.
Competitors in any category limited by age shall have an official document giving their date of birth.
Competitors will be given a map, starting ticket, and identifying number. The starting ticket must be marked at each transmitter found, and returned at the finish line. Transmitters may be found in any sequence.
T he host society will establish procedures for starting order, start corridors, waiting areas, control of equipment, etc., as appropriate. The rules from other IARU regions serve as a model. The rules must be easy to understand and follow for all participants.
Timeout: The maximum time allowed on the course shall be announced before the start of the course, and will be at least 2 hours. Any competitor exceeding this time shall be disqualified. The host organization may also, at their discretion, modify the timeout period the day of the event to take into account for any unexpected situations such as weather. The timeout period may not be modified once the event has started.
