Finally got around to seeing why TR tells me UA0SMF is 12000 km away from at a bearing of 166 degrees. Tried UA9* & UA0* - only UA0S, T & W are off. Way off. Presumably a negative in front of what should be a positive number or vice versa for the position of those locations? The data for this isn't in CTY.DAT... 73, VR2BrettGraham
