On April 5, 1999, at Midnight, WDUV swapped its frequency with classic rock station WTBT, moving from 103.5 to the 105.5 signal (WTBT is now WFUS). However, both frequencies would retain their transmitting locations and cities of license. After the swap, WDUV became licensed to New Port Richey with transmitting facilities in Holiday, while WTBT, whose transmitter was located in Riverview, became licensed to Bradenton. (WTBT, now WFUS, has since been relicensed to Gulfport.) While the 105.5 transmitter is more powerful, it is also further away from the population center of the Tampa-St. Petersburg-Clearwater market than 103.5's transmitter. Because WDUV is aimed at an older audience, Cox saw more potential gain with WTBT at 103.5.
