"The RSGB Contest Committee has revised the VHF General Rules
relating to the use of the DX Cluster and other spotting/chat networks (including
internet facilities for example ON4KST) in RSGB VHF and UHF contests.
The revised rules are listed below:
4i. The active use (posting messages, arranging skeds, self spotting etc) of the DX Cluster and other spotting networks (including internet facilities for example ON4KST) to assist an entry to a contest on 6m, 4m, 2m and 70cm is banned in all RSGB contests with the exception of three IARU Region 1 co-ordinated contests (50MHz Trophy in June, 144MHz Trophy in September and 432MHz to 248GHz IARU in October) and the 144MHz Marconi contest in November where permitted by the IARU rules for these contests. You may spot a DX station as long as your operating frequency is not given.
4k. All information must be copied off air at the time of the QSO and on the band in use. Databases must not be used to fill in missing information. The DX Cluster, talkback channels etc must not be used for passing or confirming any contest related information.
These revised rules take effect from midnight 30th April 2007."
