If you are having problems with interference, the EMC help desk is there to help, and can be contacted by e-mail on helpdesk.emc@rsgb.org.uk The helpdesk, coordinated by Ken, G3SDW, operates via e-mail, calling on many years of experience of dealing with interference problems. They do not carry out home visits except in very exceptional circumstances. This service is operated by volunteers in their own time and will be provided via e-mail. Requests to correspond via the telephone, especially to mobile numbers are to be avoided. Don’t forget, the RSGB do not have any powers of enforcement. If this is required you should contact the regulatory body, Ofcom. Locating the source of interference, particularly if it is outside your own premises, will require a certain amount of leg work. If you are unable to do this, you may be able to enlist the help of another amateur or local club.
