Despite its UHF frequency, the height of WNGH's transmitter gives it one of GPB's largest coverage areas.[not verified in body] It penetrates for some distance into the area of Chattanooga, Tennessee; Chatsworth and Dalton are part of the Chattanooga media market. It provides at least secondary coverage as far north as Athens, Tennessee, and as far south as metro Atlanta's north-northwestern suburbs, many of which can no longer receive GPB's flagship station, WGTV (channel 8).[not verified in body] Two translator stations help bring the signal to the mountainous parts of the service area. Some network program duplication occurs with WTCI-TV (channel 45), the main PBS station for the Chattanooga area.[not verified in body]

HistoryEdit

The station made its first broadcast on January 30, 1967, as WCLP, a National Educational Television (NET) and Georgia Educational Television network affiliate. It was Chattanooga's first educational television station, joined by WTCI-TV in 1970. On February 2, 1979, the station branded itself as WCLP-TV. In 2002, WCLP's digital signal started on channel 33.

On April 15, 2008, WCLP-TV changed its call sign to WNGH-TV, to match GPB's new local FM-radio station, WNGH-FM. The FM station's transmitter was moved to the same broadcast tower as the TV station atop a mountain within Fort Mountain State Park.

Due to equipment failure in 2008, the station's analog signal operated at reduced power (1,500 kW, 30% of normal) until it switched entirely to digital.

TranslatorsEdit

WNGH has broadcast translators which extend the station's coverage into areas blocked by distance or terrain, notably by the north Georgia mountains. All of these translators have been located near the state's border regions with Alabama, Tennessee, and North Carolina.

Currently,[when?] only the W12DK-D translator is operating, under a broadcast license which covered its construction permit in December 2009.[clarification needed] It is atop Brasstown Bald, the highest point in the state, which is anticipated to be shared by the 97-watt GPB radio station WBTB FM 90.3.

W12DK-D replaced two other stations:

Four other stations near Alabama had their analog licenses and digital applications or construction permits canceled, apparently at GPB's request:[citation needed]

This was the largest number of translators assigned to any of the GPB stations. Two others are currently assigned to primary (parent) station WGTV, though all stations simulcast at all times.

Analog-to-digital conversionEdit

WNGH-TV shut down its analog signal, over UHF channel 18, on February 17, 2009. This was the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts. The station's digital signal remained on its pre-transition UHF channel 33.[3] Through the use of PSIP, digital television receivers display the station's virtual channel as 18, its former UHF analog channel.
