 KOOV was always challenged by a poor signal in the hills of Central Texas because of its Class A status due to other nearby stations on the same or nearby frequencies.The original power was 3,000 watts, but lowered to 980 watts as the station's antenna was raised from 300 feet to 500 feet atop Hogg Mountain.In the early 1990s, the station finally was upgraded to Class C3, increasing its effective radiated power to 8,600 watts from a new self-supporting tower on the far west side of Copperas Cove near the Lampasas/Coryell County line.
