The OK/OM DX Contest is an annual CW event that brings together amateur radio operators from around the world. We participate to contact as many stations as possible, particularly focusing on working stations in the Czech Republic (OK) and Slovakia (OM), and other countries and continents across the globe. The contest runs for 24 hours, starting at 1200 UTC on the second full weekend of November. We make contacts on 160m, 80m, 40m, 20m, 15m, and 10m, exchanging basic signal reports and a sequential contact number, or a county code if we are an OK or OM station. It's a great opportunity to test our station's capabilities and make new contacts. 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.
