Each HQ station counts as an additional call area, and entrants may contact any HQ station (including any in their own call area) for points and bonuses.

    (d) The entire UK&CD counts as one Call Area, so UK&CD stations may not work each other for points. The only exceptions are UK&CD 'HQ' stations which may be active from more than one of the UK&CD prefix areas; these may be contacted for points and bonuses by UK&CD stations.

    (e) UK&CD entrants must be RSGB members

    (b) A bonus of 20 points is earned for each of the first three contacts with a Commonwealth Call Area on each band.

    (c) Commonwealth Contest Team Competition scoring: The team score is the sum of individual adjudicated scores, with all stations located in the southern hemisphere or on the equator having their final score multiplied by a Latitude Factor.

    (d) This Latitude Factor will be recalculated each year based on published scores. For each hemisphere, the highest-scoring team total for each of the last three years will be used to give an overall total and the factor will be calculated as the ratio of the northern to the southern grand totals rounded down to the nearest two decimal places.
