As the ABC signal was being transmitted via traditional microwave from AT&T into the studios of then-ABC affiliate WTVK-TV on Sharp's Ridge in Knoxville (now CBS affiliate WVLT-TV), WKPT would literally "grab" the telco signal just as it reached WTVK's studios. It then sent the signal via private microwave to a relay station line-of-sight east to Camp Creek Bald on the Tennessee/North Carolina border in southern Greene County, Tennessee. The ABC signal was then re-transmitted via another WKPT microwave line-of-sight further east to the WKPT transmitter site on Holston Mountain. From the relay point there, it was transmitted by a third WKPT microwave line-of-sight down to the studios in downtown Kingsport through the station's master control board and then back to Holston Mountain via the station's regular studio-transmitter link and then broadcast on channel 19.
