The long weekend in March will be a WARG Practical – Cavity Modification and Consolidation day. All are invited to get involved with commercial cavity modification for use on 2m repeaters. Please bring along any drills, holesaws and basic tools you may have. Learn a thing or two about cavitiy filters and how to modify them for AR use. Time permitting, some of the older existing WARG cavities will be inspected/tested/tuned for future works.
