WMTJ (channel 40), branded Sistema TV, is a PBS member television station serving San Juan, Puerto Rico that is licensed to Fajardo. The station is owned by Ana G. Méndez University (UAGM). WMTJ's studios are located on UAGM's main campus in the Cupey district of San Juan, and its transmitter is located in the El Yunque National Forest.
WMTJ has one full-service satellite: WQTO (channel 26) in Ponce. WMTJ's digital signal was not on the air until a few months before the transition deadline. Installation of a digital transmitter for WMTJ had been difficult as the transmitter site is located in a remote tropical forest on national park land, requiring USDA Forest Service approvals of any new transmission tower.[1]
History
WMTJ first broadcast in April 1985.
Due to damage from Hurricane Maria, WMTJ was forced to go off the air on September 20, 2017 (the station's website still lists the schedule from September 11 to 17, 2017 with some shows no longer on the schedule such as Thomas & Friends).[2]
