Rules

Bunbury Dunnies on the Air is a light hearted, short duration competition for people interested in radio organised by the Bunbury Radio Club. It involves teams making contacts via radio methods where at least one of the teams is activating a registered toilet. Points are awarded for each logged contact and the winners of the competition are the teams that accumulate the most points for the duration of the contest in either the Chaser or Activator category.

The purpose of the competition is to have fun, gain experience in safe portable operations and to promote amateur radio. Safety of the general public and participants is a priority. We need to be mindful of the other users of the conveniences so we don’t inconvenience them.

Duration: The competition starts at 1215 local time (0415 UTC) and ends at 1315 local time (0515 UTC) on Saturday 14th November 2015.

Activators: teams who are visiting the toilets, setting up portable stations (which may be as simple as a hand held radio) and making contacts. Activators earn points for the contacts they make as activators AND contacts they make as chasers as they move between toilets.

Chasers: individuals or teams making contacts with activators.

Teams: Activator teams comprise two or more people. A multiplier of 1.1 applies to teams including a person who is not a licenced radio amateur and a person who is a licenced amateur. Multiple operators and multiple radios are allowed, but only one contact at a time can take place. Each team has a name that is used as part of the contact exchange. Chasers can be individuals or teams.

Registered Toilets: Activations are made by a team operating portable from a registered toilet. The list of registered toilets is published a fortnight before the competition. These toilets are a subset of the public toilets in the vicinity of the City of Bunbury. Each toilet has an official number allocated to it by the federal government.

Activating: For the points for a contact to be counted in the competition, one of the teams involved in the contact must be ‘activating’ a registered toilet. Activating a toilet involves transmitting pedestrian mobile within 100 metres of a toilet and making contacts with other teams. Activation points are awarded for the team activating a toilet for all contacts made from the toilet, provided the activating team has made contacts with at least two other teams from the toilet. If less than two other teams are contacted, the activation is still valid, but activating points are not awarded.

Activations are unassisted portable. No reliance on a vehicle for power, antenna mounting etc is allowed. The team must operate closer to the toilet building than they are to the support vehicle and within 100m of the toilet and with a line of site to the toilet.

More than one team can be activating a toilet at the same time, but contacts between them do not earn points for either team.

Contacts: When a team activating a toilet calls another team, a valid contact is made when the teams exchange their name and location. Toilet locations can be passed as the toilet number and official name, or just the word “Toilet” and the number. Any other information legally require on the band in use (for instance amateur call signs) should also be passed, but do not form part of the contact for the purpose of the competition. Multiple contacts between two teams from the same locations are counted, up to three, if they occur on different bands. For the purpose of this, simplex and repeater operation count as different bands.

For example if two teams make contact on the 2m repeater, 2m simplex, and 70cm simplex – this counts as three valid contacts that will earn points. Any further contacts between these two teams on any band do not count as valid unless at least one of the teams moves to another toilet.

Self spotting and organising scheds on or off air by any method are allowed.

Points: are awarded for valid logged contact exchanges between:

Activated toilet to chaser – 5 points
Chaser to activated toilet – 1 point
Activated toilet to (different) activated toilet – 10 points

Points are also awarded for a conversation with a member of the public promoting amateur radio. This needs to be witnessed by another team member and logged. – 20 points.

The points for the conversation only apply to the first conversation at that location.

To determine the winner, all the points for a team will be summed before the multiplier (if applicable) is applied.

Logs: Teams need to keep a log of their contest contacts. These are used to calculate their score and can be cross checked with other participants to confirm the veracity of scores claimed. Logs need to include the names of the two teams, time, frequency, name of the toilet or toilets, and the points claimed. Paper proformas and an online logging system will be made available to teams before the start of the event

Radio Methods: The radio method used to make the contacts can be any legally used non-consumer radio transmitter. Some examples of consumer radio that would not be counted would be bluetooth, wi-fi, or cellular telephone. Examples of legal non- consumer radio would be any amateur radio, UHF or HF citizens band radio, or private business radio.

In practice, it’s likely (but not required) that most contacts will be initiated on the VK6RBY 2m repeater, then repeated on the 2m and 70cm simplex frequencies (146.5MHz & 439.0MHz) or the UHF CB calling channel 11.
