WMTJ is an educational, full-service, PBS member television station licensed to Fajardo, Puerto Rico transmitting over digital channel 16. The station is owned by the Ana G. Méndez University System and is branded as Sistema TV. Its main studios are located in San Juan.
The majority of the station's daily programming is from PBS, but it has some locally produced content as well.
WMTJ has one full-service satellite: WQTO, digital channel 25, in Ponce. WMTJ's digital signal was not on the air until a couple months before the transition deadline. Digital transmitter deployment for WMTJ had been proven difficult as the transmitter site is located in a remote tropical forest on national park land, requiring National Forest Service approvals of any new transmission tower.
