Channel 83

From Wikipedia, the free encyclopedia

Channel 83 has been removed from television use in 1983. The highest frequency to have been used for NTSC-M terrestrial TV broadcasting, it was formerly used by a handful of television stations in North America which broadcast on UHF frequencies 885.25-889.75 MHz. In the United States, channels 70 - 83 served primarily as a "translator band" for low-power repeater transmitters filling gaps in coverage for existing stations. Many are defunct, with the few still in existence now moved to lower frequencies:

• KARE (NBC Minneapolis) rebroadcaster K83AE Redwood Falls, Minnesota moved to K68BJ channel 68.
• KLBK-TV (CBS Lubbock) rebroadcaster K83AQ Matador, Texas moved to K47GE channel 47.
• KHQ-TV (NBC Spokane) rebroadcaster K83AJ Quincy, Washington moved to K48BY channel 48
• KOAT-TV (ABC Albuquerque) rebroadcasters K83BK Carrizozo, New Mexico moved to K43BT channel 43 and K83BL Montoya-Newkirk moved to K57BR channel 57.
• KPNX (NBC Phoenix) rebroadcaster K83AC Globe, Arizona moved to K61FB channel 61.^[1]
• KRDO-TV (ABC Colorado Springs) rebroadcaster K83BP Deora, Colorado moved to K49BT channel 49.
• KRQE (CBS Albuquerque) rebroadcaster K83AB Santa Rosa, New Mexico moved to K38HR channel 38.
• KSAT-TV (ABC San Antonio) rebroadcaster K83BO Uvalde, Texas moved to K65EQ channel 65.
• KSL-TV (CBS Salt Lake City) rebroadcaster K83AF Delta, Utah moved to K39FR channel 39.
• KTTC-TV (NBC Rochester, Minnesota) rebroadcaster W83AH LaCrosse, Wisconsin moved to W67CH channel 67
• KUED-TV (PBS Salt Lake City) rebroadcasters K83BB Duchesne, Utah moved to K03CN channel 3, K83BD Marysvale, Utah moved to K46FX channel 46 and K83BC Virgin, Utah moved to K25HB channel 25.
• WXXW-TV (now WYCC PBS Chicago, Illinois) had used channel 83 to operate a repeater from 1965-1972, now defunct.^[2] The main channel 20 transmitter now operates from the Sears Tower, a building completed in May 1973.
• A Radio Shack device, the Multiple Video Distribution System (150-1284), was marketed in the early 1980s with the capability of block conversion of up to three independent RF modulator signals from VHF channel 3/4 for home viewing on any of channels 74/75, 78/79 and/or 82/83 - channels which remained unused in most markets. All recent versions of the product were forced to lower frequencies by the removal of UHF channels 70-83 from later-model television receivers.^[3]
