In Grand Theft Auto: Vice City, Fernando Martinez hosts the radio station Emotion 98.3.
Emotion 98.3 is Vice City's soft-rock and power-ballad station, fitting the game's exaggerated 1980s Miami setting. Its programming includes romantic and dramatic songs, creating a deliberately sentimental contrast with the violence and criminal ambition of the game's storyline.
Fernando Martinez presents himself as a flamboyant romantic expert and an exaggerated Latin lover. His radio persona is part of a recurring character arc across the Grand Theft Auto series. Fernando also appears in Grand Theft Auto III and Grand Theft Auto: San Andreas, where later appearances add context to his sometimes comic claims about relationships and romance.
The other options are also Vice City radio stations, which makes this an easy detail to confuse. V-Rock focuses on hard rock and metal, Wave 103 plays new wave and synth-pop, and Flash FM features pop music. Emotion 98.3 is the station identified with Fernando.
