Channel 75  Channel 75, removed from television use in 1983, was formerly used by television stations in North America which broadcast on UHF frequencies 836-842 MHz. In the United States, channels 70-83 served primarily as a "translator band" containing repeater transmitters to fill gaps in coverage for existing stations. A handful remained in licensed operation in remote locations for years after the frequencies were lost to AMPS cellular telephony and the channels removed from tuners on new televisions, often running unattended and unmonitored. Many of these tiny rebroadcasters have left the air; those which remain were moved to lower channels after 1983, typically to channels which required they move again when UHF TV channels 52-69 were lost in 2009-2011. In Canada, the frequency was assigned to a small rebroadcast transmitter serving one tiny village Clermont, Québec on La Malbaie where terrestrial obstacles blocked the main signal. CFCM-TV (Québec) rebroadcaster CJVC-TV operated from 1958 to the mid-1960s. CFCM, a Radio-Canada affiliate at the time (1954-1964), later became a TVA station. The channel 75 transmitter was replaced by CJBR-TV (Radio-Canada Rimouski) rebroadcaster CFCV-TV Clermont, Québec in the mid-1960s to retain Radio-Canada programming. CFCV was replaced by ten-watt CBSAT channel 21, then went dark as all CBC/Radio-Canada owned and operated rebroadcasters were shut down nationally on August 1, 2012. All other assignments have been to low-power rebroadcasters of US stations:  In Australia the Seven Network broadcasts Openshop. The channel started broadcasting from August 1 2019
