Okay, I think I know what it might be doing. I've found N8OH in my TRMASTER file after UEFV. There was no N8OH in my original TRMASTER file, nor the old call of WB8GNX. However, I did find: WB8G =H1 And after UEFV: N8OH =H1 =OWB8GNX It looks like UEFV will act, even if there is a partial match. 73, VR2BrettGraham
