WRHM (107.1 FM) is the flagship station of Interstate 107, the branding of two country music format stations in Rock Hill, South Carolina (107.1 WRHM) and Chesterfield, South Carolina (107.3 FM WVSZ).
Officially licensed to Lancaster, South Carolina, Interstate 107 broadcasts from the WRHI/WRHM studios at 142 North Confederate Ave. near Downtown Rock Hill.
WRHM operates at a relatively modest 2,400 watts from a somewhat short (by modern broadcasting standards) 524 ft (160 m) tower on the northern tip of Lancaster County.
WRHM programming is also simulcast on WVSZ, licensed to Chesterfield, South Carolina.
WRHM was called WLCM-FM and WPAJ when it was in Lancaster, and the format was soft adult contemporary.
