1510's original callsign was KCAW (stood for Country And Western) and the original tower used by the station was in Port Arthur, Texas. That tower now is used as a cell site tower. The transmitter was moved to its current South Vidor location (where its former FM sister was located) when the FCC approved a power increase from 1,000 watts to the current 5,000 watts. The callsign changed to KYKR along with its sister 93.3 FM in the early 1980s. Eventually, owner Jimmie Joynt sold both the AM and FM to different owners. 1510 saw a couple of different owners (including Clear Channel at one time) including religious owners and a change of Community of License (COL) from Port Arthur to Nederland, TX because the studios were located there for a while.
