Atlanta, TX (in NE Texas near Tyler/Longview) was allocated 1610 at the start of the EX band....I dont recall if it was built and on air but the allocation was dropped a few years later..and noone has bothered to file for a 1610 allocation since (well, no windows existed I think)...I am surprised noone else ever filed to move a 1600 to 1610 as a minor change...but the EX band rules are different and moves into it can take YEARS...see WRCR in NY as proof)
1610 is NOT allocated to TIS only..they are secondary to any broadcast station allocated (which broadcast is primary 1610-1700)
