Picked this up on Partridge tower. It's a TG for KDOT flaggers. Does each KDOT District/Area have their own TG for flaggers? I also heard some KDOT chatter that specifically referred to a "talkaround flagger channel".
I thought I'd run it through here first before submission to get the big picture. Thanks.
I don't have an answer about KSICS TGs for flaggers, but fairly recently I heard KDOT flaggers using simplex analog 855.9625. They may have moved to the digital trunk even more recently.
