On December 28, 2006, WAHU launched its digital signal on UHF channel 40. While providing an over-the-air standard definition Fox feed on its first digital subchannel, the station began airing a dedicated MyNetworkTV channel on a new second one. Following this addition, the station shifted several programs to the digital subchannel. Prior to the addition of WAHU-DT2, the network was added on September 5, 2006 as a secondary affiliation on the main channel. As part of the launch, Comcast moved WTTG from channel 9 to channel 18 in order to give WAHU the lower channel location.
