WYMM (1530 AM) is a commercial radio station in Jacksonville, Florida, broadcasting a Caribbean format.
Its transmitter, studios and offices are on Picketville Road in the Biltmore neighborhood of Jacksonville.
It operates with 50,000 watts, the maximum power permitted by the Federal Communications Commission.
Because 1530 AM is a clear channel frequency reserved for Class A stations WCKY Cincinnati and KFBK Sacramento, WYMM must go off the air at night to avoid interference.
Prior to March 2014, it was "La Poderosa", playing a Regional Mexican music format.
