I have a list of talkgroups for an edacs system that I have been monitoring with T4Win. I am going back through the Talk group screen and changing the unknown to their proper name. When I try to display the talkgroups in AFS format, T4win shows the wrong TG number. example TG 05-121 displays as 05-101. this doesn't seem to be a uniform off by 20 conversion though. When they are displayed in Hex though, they are the correct number. I know you can use the scientific calculator to convert, but that would take forever as I have 150+ TGs. is there a simple formula I can copy into a spreadsheet and then convert my talkgroups, or do I have to do it 1 by 1?
