WLHZ-LP (107.9 FM, "UncionFM 107.9") is a radio station licensed to serve Springfield, Massachusetts. The station is owned by Pentecostal Church Refuge Of Salvation. It airs a Spanish-language Religious radio format.
The station was assigned the WLHZ-LP call letters by the Federal Communications Commission on February 11, 2008.
Another Spanish-language religious station, WREA-LP in Holyoke, had also been assigned to WLHZ-LP's original 104.9 MHz frequency but in March 2008 WLHZ-LP received a construction permit from the FCC to relocate to 107.9 MHz to avoid interference with WREA-LP.
WLHZ-LP currently transmits from the AT&T mobility tower on East Mountain in Westfield. WLHZ-LP applied to change frequency to 98.7 on February 29, 2012, to alleviate interference issues from "(a) first adjacent FM station".
