WTCN-CA

WTCN-CA is the Class A, MyNetworkTV-affiliated television station for the Gold and Treasure Coasts of South Florida. Licensed to Palm Beach, it broadcasts a low-powered analog signal on UHF channel 50 from a transmitter in unincorporated Martin County (southwest of Hobe Sound) on the Jonathan Dickinson State Park boundary. The station can also be seen on Comcast channel 15 (hence the on-air branding My 15 WTCN-TV).

Owned by the Sinclair Broadcast Group, WTCN is sister to CBS affiliate WPEC, CW affiliate WTVX, and Class A Azteca América affiliate WWHB-CA. All of the television outlets share studios together on Fairfield Drive in Mangonia Park (with a West Palm Beach postal address).

Due to its Class A status, the station's low-powered directional antenna pattern prevents it from reaching Fort Pierce (to the north) and downtown West Palm Beach (to the south). In order to expand the broadcasting radius, WTCN is simulcast in standard definition on WTVX's third digital subchannel. This broadcasts on UHF channel 34.3 from a transmitter, southwest of Palm City and I-95/SR 9, in unincorporated Martin County.
