As I worked a VE1 who was giving out NS in the recent SSB Sprint, I noticed that CT10 couldn't identify it as MAR. After the contest, I checked the sprint.dat http://www.k1ea.com/dat/sprint.dat file and there seems to be a typo in the MAR line. It shows NF twice, doesn't show NS or VE1. An easy edit. Dave, W6NL
