Analog-to-digital conversion KTSM-TV shut down its analog signal, over VHF channel 9, at 12:30 p.m. on June 12, 2009, the official date on which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 16 to VHF channel 9. Due to reports of reception issues with its signal on digital channel 9, KTSM-TV was granted permission by the Federal Communications Commission to operate a secondary signal on its former UHF digital channel 16 under special temporary authorization on July 23, 2009, mapped to virtual channel 9.1. KTSM had filed a petition to the FCC to permanently operate its digital signal exclusively on UHF channel 16. It was issued a license for that channel on June 5, 2015.
