The heatmap shows the activity as reported by the RBN (CW/PSK/RTTY, no FT8) of the last 12 months. You can scroll back to January 2015.
No activity in selected time frame or the owner of the callsign does not wish to appear on this page.
Daily activity is measured by the number of active hour slots (24) times band slots (13, 160m - 2m incl. WARC and 60m) and the number of continents in which a skimmer spotted the station in the respective hour, for a maximum daily score of 24 * (13 + 6) = 456. When filtering by band, the continent information is omitted, because it's only saved once per hour slot, not per band.
