digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 18. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 6. As part of the SAFER Act, KRMA kept its analog signal on the air until July 12 to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters. KTSC shut down its analog signal, over VHF channel 8, on June 12, 2009. The station's digital signal relocated from its pre-transition UHF channel 26 to VHF channel 8 for post-transition operations. KRMJ shut down its analog signal, over UHF channel 18, on June 12, 2009. The station's digital signal relocated from its pre-transition UHF channel 17 to channel 18 for post-transition operations. KRMZ shut down its analog signal, over UHF channel 24, on February 17, 2009, the original date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition VHF channel 10. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 24. KRMU signed on in December 2004 as a digital-only station, although it also had endured a temporary shutdown in early 2009 in final preparation for the transition. Translators In addition to its five full-service television stations, Rocky Mountain PBS operates one of the largest translator networks in the country, serving portions of Colorado, Wyoming, Kansas, Nebraska and Utah. KRMA feeds two translators in Boulder and Fort Collins. KTSC feeds 10 translators in rural southern Colorado, and KRMJ feeds 13 translators serving rural western Colorado. The other translators are operated by community groups that pick up one of the three Rocky Mountain PBS regional feeds, and carry the signals onward through their systems. All 25 translators within the RMPBS system operate as digital signals, and as such carry the primary channel and two subchannels from their respective parent transmitters.
