By 1983, KFOX-FM had evolved into a multi-ethnic, multilingual format such as Radio Rangarang (Persian), Radio Omid (Persian), and Radio Naeeri (Armenian). In the mid-1990s, this became "Radio Korea USA" with an all-Korean format. This continued until 1999, when the International Church of the Foursquare Gospel (ICFG) moved the KFSG call letters and Christian radio format to 93.5 FM. This switch was a condition of selling KXOL-FM (96.3 FM), acquired by Spanish Broadcasting System specifically for the purpose of relocating KFSG. In 2002, the lease arrangement with the ICFG ended and SBS switched KFSG to a Spanish-language outlet, first as KMJR ("La Mejor") and later KZAB.
