Summary — all hours combined
(radius = QSO count per 5° slot)
QSO distance by band — box = 25–75%, line = median, whiskers = 1.5×IQR, dots = outliers (great-circle km from center)
Direction × UTC-hour activity — rows = UTC hour-of-day, columns = 5° heading; color = QSO count (rate)

Space weather vs activity — per day (QSOs as bars; SFI & sunspot number & A-index as lines)

QSOs by K-index (geomagnetic conditions you worked through; 0 = quiet, 5+ = storm)

Per-day QSO totals

CBS-style report (text statistics after "Cabrillo Statistics" by K5KA & N6TV — rate table, dupes, best rates, continent / country / multiplier by band)
