I have been hearing Troop H along with G,A,L,B,I& F all on the Troop G zone down here in the southwest part of the state. While it "could" be part of the smartzone feature, It sounds like they are broadcasting most of the troops here. The only ones that I have not heard are C,D,E,K or W. I would suggest trying some of the other control channels and see what you come up with.
