A post-mortem analysis engine for amateur radio contesting.
Professional sports teams don't just play the game; they watch the "game tape" afterwards to understand why a play failed or succeeded. Most logging software is designed for the heat of battle—getting the QSO in the log efficiently. Contest Log Analytics is designed for the day after.
By analyzing your logs against your competitors, this tool uncovers the hidden story of the contest: who owned the band at 0200Z, who found the multipliers you missed, and exactly how your operating strategy differed from the winner's.
Cabrillo logs don't record whether you were "Running" (Calling CQ) or "Search & Pouncing" (Hunting). This tool uses a sophisticated algorithm to infer your operating mode based on time and frequency deltas, creating data that doesn't exist in the raw file.
"Common" QSOs are the price of admission—everyone works them. Contests are won in the margins. Our reports isolate "Unique Run" and "Unique S&P" QSOs to show exactly where you gained (or lost) your advantage relative to the competition.
Forget manually downloading competitor logs. The analyzer now connects directly to public contest archives (starting with CQ WW). Simply select the year and mode, search for your competitors by callsign, and fetch the data instantly for head-to-head analysis.
This analyzer supports major events including CQ WW, CQ WPX, ARRL DX, ARRL Sweepstakes, ARRL IARU HF, WAE, and the WRTC. It utilizes external data files (CTY.DAT, Section files) to ensure accurate scoring and multiplier calculations.
