The station's signal targets the Research Triangle region of North Carolina, including the Raleigh radio market.

In addition to Raleigh and Durham, other North Carolina cities and towns within the station's primary broadcast radius include Apex, Butner, Cary, Chapel Hill, Clayton, Fuquay-Varina, Garner, Goldsboro, Hillsborough, Holly Springs, Kinston, Knightdale, Morrisville, Rocky Mount, Smithfield, Wake Forest, Wendell, Wilson & Zebulon.

Because AM 540 is a clear-channel frequency reserved for Canada and Mexico, WETC had to sign-off every evening at sunset to avoid interfering with skywave signals of other radio stations.

On March 25, 2016, WETC was granted a construction permit from the Federal Communications Commission (FCC) to increase its daytime power to 10,000 watts.

On October 1, 2018, Divine Mercy Radio filed a Remain Silent Authority application with the FCC, citing major technical issues.
