KCWT-CD
KCWT-CD, virtual channel 21, is a low-powered, Class A primary CW+-affiliate and secondary Public Broadcasting Service member television station licensed to McAllen, Texas, United States. Owned by Entravision Communications, it is sister to McAllen-licensed Univision affiliate KNVO and, as well as two other McAllen-licensed low-power stations: Fox/MyNetworkTV affiliate KMBH-LD, channel 67 and Class A UniMás affiliate KTFV-CD. Entravision also operates Mexican station XHRIO-TDT. KCWT-CD, KNVO, KFXV, KMBH-LD, KTFV-CD, and XHRIO-TDT share studios on North Jackson Road in McAllen; KCWT-CD's transmitter is located in La Feria, Texas.
Previously, KCWT was a low-powered translator of KXFX-CA and KTFV-CA.History
Until 2014, KCWT broadcast on analog channel 30. KCWT launched a digital feed on RF channel 23 that March; however, through the use of Program and System Information Protocol, the station maps to virtual channel 21, as nearby Mexican station XHAB-TDT in Matamoros, Tamaulipas, whose digital broadcasts use RF channel 30, also mapped to virtual channel 30 rather than its analog channel 7 due to Mexico not fully following the PSIP standard. Even before then, KCWT, as had previous CW affiliate KSFE-LD, has long branded as "CW 21" in reflection of its channel 21 slot on area cable systems.
