I pulled spot counts for the Top-Ten SOHP stations, as reported so far to 3830 (plus CR3E who has not posted yet). Note that if you were spotted once a minute for 48 hours, that would add up to 2880 spots.
Most Spotted USA (SO HP)
Most spotted DX (SO HP)
N4ZR adds: Also, you *must* send TEST or CQ, or you will not be spotted. These are keywords that Skimmer uses to identify running stations. No keyword, no spot.
Of course, the numbers above reflect the geographic distribution of RBN Skimmers. It is surprising, though, that given the density of RBN contributors in Europe, only CR6K and 4O3A made the list. Perhaps there aren't very many competitive high-power single-ops in Europe, or maybe they were all off operating at the big multis.
