Until February 9, 2007, WTMO's primary signal (as WTMO-LP) was the WKME transmitter. Until early 2006 at the latest, it was located on channel 40, but moved to channel 15 shortly before WACX signed on its digital signal on channel 40. Based in Kissimmee, this signal is far enough away with a directional pattern towards Kissimmee, so it would not interfere with WCEU (now WDSC-TV), which also broadcasts on channel 15. As a result, channel 15's coverage area only covers Kissimmee, forcing WTMO to reach the rest of the Orlando area via cable. In late 2006, ZGS acquired WDYB, WMVJ, and the channel 31 license (then WPXG-LP) from Tiger Eye Broadcasting to expand WTMO's over-the-air reach. The station began broadcasting in digital on RF channel 31 on 10 August 2011.
