Since the power increase to 850 watts, and moving the transmitter to Shinall I can actually hear them most of the time on my low VHF/FM "DX" setup (Sangean HDT-1, RS VU190 VHF/UHF TV antenna, CM Spartan Preamp) near Star City. This morning, KZTS is full quieting. Before the power increase on the temporary antenna site they were seldom heard unless there was some decent tropo scatter.
That said KZTS might get win over a few hip-hop listeners in metro LR, but they won't be a player in Pine Bluff unless they get another frequency. The few ads I've heard were for cellphone resellers, clubs, etc. The audio quality is somewhat better than KIPR, but I'm no fan of hip-hop/gangsta rap so....
