Internet RDF Mailing Lists

By subscribing to Internet mailing lists (also called reflectors, groups and forums) for your favorite RDF-related topics, you can keep in touch with the activities of other RDF enthusiasts and discuss topics of mutual interest with them.  When any list member sends (posts) a message to the list, all subscribers automatically receive the message and can respond either to the sender or the entire list.

Southern California ARDF List

This list is for announcements and results of on-foot and international-style (IARU) radio-orienteering events in southern California, from San Luis Obispo to the Mexican Border.  It is used to coordinate future events, publish the results, and make plans for attendance at upcoming championships.
