Early broadcasters in the 1950s and 1960s quickly realized Holston Mountain as a prime radio-television transmission location because it is the highest visible point that faces most of the major cities in
Upper East Tennessee and Southwest Virginia in the surrounding valley between
Knoxville, Tennessee, to southwest of
Roanoke, Virginia. As a result, the Holston Mountain ridge is the transmitting site for five television stations in the
Tri-Cities, Tennessee Television
Designated Market Area (DMA). The digital broadcasting antenna for
WCYB, digital Channel 5, Bristol, Virginia is on
Rye Patch Knob, with the top of the antenna above ground, above the surrounding valley floor, and above mean sea level. The single tower that antenna sits on, is the highest and tallest man-made structure on the mountain, allowing the Virginia station to transmit from the highest broadcasting point in Tennessee, Virginia and Kentucky. The television towers for
WJHL, digital Channel 11,
Johnson City, Tennessee, and
WKPT, digital Channel 19,
Kingsport, Tennessee, are standing side by side in a common broadcasting antenna farm on the southwest slope of
Holston High Point, southwest of
Rye Patch Knob. The antenna for
WJHL stands above ground, above the surrounding valley floor, and above mean sea level. The antenna for
WKPT next door stands above ground, also above the valley floor, and above mean sea level. The transmitter for
WEMT, digital Channel 39, licensed to
Greeneville, Tennessee was relocated from
Camp Creek Bald (Viking Mountain) south of Greeneville to the
WCYB digital tower on Rye Patch Knob, when ownership of WEMT was acquired by the
Sinclair Broadcast Group, owners of WCYB. Holston Mountain is also the transmitting site for three FM Class C radio stations:
WTFM-FM 98.5, Kingsport, Tennessee;
WXBQ-FM 96.9, Bristol, Virginia and
WETS-FM 89.5, Johnson City, Tennessee. All three antennas and the backup antennas are located at the antenna farm on the southwest slope of
Holston High Point. Also located on the ridge are the antenna for one FM Class C1 radio station, WHCB-FM 91.5, Bristol, Tennessee, located at
Rye Patch Knob; one FM Class C2 antenna for radio station WCQR-FM 88.3, Kingsport, Tennessee, and one FM Class D antenna for radio station W214AP-FM 90.7, Johnson City, Tennessee, both transmitting from the antenna farm on the southwest slope of
Holston High Point. Located further down the southwestern slope, off of Holston Mountain Road, is the transmitting site of FM Class C3
WEXX 99.3,
Elizabethton, Tennessee. Various U.S. federal, Tennessee state, Sullivan, Washington and Carter County governmental agencies, along with utility microwave relay stations, also transmit base-to-mobile communications from the
Holston High Point antenna farm and
Rye Patch Knob. Holston Mountain is also home to several amateur radios transmitter sites. wm4t repeater site sits on the highest peak of the mountain for two-way radio service. This site covers seven states in communications. The tower (shown below) is 120 feet self-supporting. It tops out with an antenna on top of 18 more feet. ==Antenna farms==
