Data Mining Digital and RTTY Contests 2025

Presented by Tim Shoppa, N3QE at Hamvention 2025. The presenter dives into the world of data mining for RTTY and digital contests, pulling from a decade of public contest logs to uncover trends, overlaps, and insights. A special focus is given to digital modes like FT4 and FT8, with breakdowns of participation across contests such as CQ WW RTTY, ARRL Digi, WW Digi, and the new FT Challenge. The presenter compares logs, discusses operating strategies, and highlights how solar cycle 25 is currently influencing band conditions — particularly emphasizing opportunities on 10, 15, and 20 meters during peak solar activity. Frequencies, mode overlaps, contest software, and operating tips all take center stage, with guidance on how to avoid digital QRM and stay within FCC rules. Real-world examples from high-performing stations illustrate how contesters are using band edges and less crowded segments to maximize results. The presenter also explores the growing weekly and monthly digital sprints, encouraging operators to use these events for practice and readiness. Whether you're deep into contesting or just getting started, there's a data-backed takeaway in this session.
