WRUM (100.3 FM) is a commercial radio station in Orlando, Florida, known as "Rumba 100.3." It airs a Spanish-language radio format featuring Latin pop, Reggaeton and Tropical music, and is owned by iHeartMedia.   The studios and offices are on Maitland Center Parkway in Maitland. 
In 1971, the simulcast ended. WKIS and WKIS-FM were sold to separate companies, with the FM station acquired by the Shamrock Development Company.  The new management installed an progressive rock format, switching the call sign to WDIZ. Over time, the station's playlist focused on the top selling albums and rock artists, as the station shifted to album-oriented rock.
In 1996, the station switched to all oldies as WSHE.  San Antonio-based Clear Channel Communications acquired the station in 1997. Clear Channel was the forerunner to today's iHeartMedia. In 2004, the call letters were switched to WEBG. 
On April 19, 2017, WRUM-HD2 launched a bilingual CHR format, branded as Boom 97 Uno. It was simulcast on FM translators W246BT 97.1 FM Clermont, about 20 miles west of Orlando, and W246CK 97.1 FM Kissimmee, a few miles south of Orlando. 
However, due to a trademark claim by Radio One (which uses the "Boom" brand for its classic hip hop stations), the HD2 subchannel and FM translators were rebranded as Oi2 97 Uno (pronounced "Oidos") on May 4, 2017. On February 8, 2018, WRUM-HD2 became Mega 97.1.
