RSGB Commonwealth Contest Rules
The Commonwealth Contest promotes contacts between stations in the Commonwealth and Mandated Territories. A more relaxed contest environment gives the opportunity to work some choice DX.
Date: see RSGB Contest Calendar
Time: 1000 -1000UTC
Bands: 3.5, 7,
14, 21, 28MHz. Activity
is normally concentrated in the lower 30kHz of each band
Exchange: RST plus serial number. HQ stations will additionally send HQ, which must be logged
1. Eligible entrants:
Land-based stations operated by licensed radio amateurs within the Commonwealth or British Mandated Territories (as defined by the RSGB call-area list) are eligible to enter. UK entrants must be members of the RSGB. Sections (a) and (b) are for single-operator stations who may not receive any assistance whatsoever during the contest, including the use of spotting nets, packet cluster or other assistance in finding new contacts or bonuses. Additionally, with the specific exception of the HQ station GB5CC, UK stations may not use any special callsign. Remote operation is permitted, but in addition to the requirements of the General Rules, the operator must be within the same Commonwealth Call Area as the other elements of the station.
24 hour operation - full legal limit on power - no antenna restrictions.
12 hour operation - full legal limit on power - no antenna restrictions.
24 hour operation - output power limited to 100 watts - antenna restricted to single element.
12 hour operation - output power limited to 100 watts - antenna restricted to single element.
For stations in the 12-hour categories, off periods must be clearly defined in the Soapbox field of the Cabrillo file and a minimum of 60 minutes in length. However, time before the first contact, and after the final contact, may be of any length. Stations opting to operate for a maximum of 12 hours will be annotated in the results listings.
The term “single element” defines each antenna (eg. dipole, vertical, long-wire, etc), and does not preclude the use of different single-element antennas during the contest. However, the concurrent use of one single-element antenna for transmitting and another (eg beverage) for receiving is not permitted.
(c) Multi-Operator / Assisted
24 hour operation - single transmitted signal - full legal limit on power - no antenna restrictions - packet cluster use permitted.
3. Scoring: Contacts may be made with any station using a Commonwealth Call Area prefix, except those within the entrant's own call area. Note that for this contest, the entire UK counts as one call area, and therefore UK stations may not work each other. Each contact scores 5 points with a bonus of 20 points for each of the first three contacts with each Commonwealth Call Area on each band. Commonwealth Call Areas
4. Headquarters stations: A number of Commonwealth Society HQ stations will be active during the contest and will send HQ after their serial number, to identify themselves. Only one HQ station is permitted per Commonwealth Call Area. Each HQ station counts as an additional call area, and entrants may contact any HQ station (including one in their own call area) for points and bonuses, the annotation HQ being made in the log where appropriate.5.
