Channel 74 has been removed from television use in 1983, but was formerly used by television stations in North America which broadcast on 830-836 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:
WMGT-TV 74 Adams, Massachusetts later became WCDC-TV channel 19, a rebroadcaster of WTEN-TV Albany, New York. The station’s license was canceled after its spectrum was sold at auction.[1][2]
KEZI-TV (ABCEugene) rebroadcaster K74AJ Cottage Grove, Oregon moved to K56DK channel 56 and later to K42HK-D, digital 42 as part of a group of six local digital repeaters operated by non-profit South Lane Television, Inc.
KOIN (CBSPortland) rebroadcaster K74BE Hood River, Oregon moved to K53EI channel 53 and later K24KG-D digital 24, operated by Rural Oregon Wireless Television as part of a four-station local repeater cluster.[4]
