The JIDX CW Contest is an exciting event where we aim to make as many contacts as possible over a full weekend, starting Saturday morning and concluding Sunday afternoon UTC. For those of us outside Japan, the goal is to contact Japanese stations in as many different Japanese prefectures and JD1 islands as possible, while Japanese participants strive to work DX stations across the globe in as many DXCC entities and CQ Zones as they can. We operate on 10m, 15m, 20m, 40m, 80m, and 160m using CW. The contest runs for 30 hours, providing ample opportunity to chase those elusive multipliers. We exchange basic contact information with other stations, logging each successful QSO. For first-time participants, we recommend focusing on one or two bands to get a feel for the contest flow. Always check the official rules for exact entry categories, exchange formats, and scoring details.
