This is the first time I've seen this happen. Two spots of G3RTP were uploaded with the wrong call (RA0SX).
I checked some of my old hashtable.txt numbers and found that G3RTP and RA0SX have the same number 22879.
(from ALL_WSPR.txt)
161121 1420 2 -26 -0.8 18.1060192 [RA0SX] IO90LV 30
161121 1442 2 -26 -0.9 18.1060187 [RA0SX] IO90LV 30
161121 1450 2 -25 -0.9 18.1060187 G3RTP IO90 30
Please change the two spots of RA0SX to G3RTP.
Thanks.
