Hosted by Adam First, who is voiced by Jamie Canfield, Wave 103 features New Wave and Synthpop music. Wave 103 is one of two preferred radio stations tuned in by the Streetwannabes, the other station being Flash FM. Wave 103 can be heard after Tommy carjacks their gang vehicles. An album of the songs from the station is available separately or as part of the Vice City soundtrack box set. Customers received this volume when they placed a pre-order down payment of $10 on the PC version of the game at Best Buy. The name of the station apes that of an actual local radio station Wave 102 in Dundee, Scotland, the original birthplace of the game's design company Rockstar North. The name may also allude to the New Wave music on the station's playlist.
Flash FM's "Japanese Boy" also appears on the European version of the Wave 103 CD album.
Like most DJs in Vice City, Adam believes that his kind of music is the best. He further fancies himself a music connoisseur, despite making some glaring mistakes such as calling 1986 the "finest hour" for Blondie, when in fact the band broke up in 1982.
From his chatter on the radio it is known that he likes money, is a big fan of hang gliding, and despises music videos because they show that the artists' looks are more important than actual talent. He seems to have some kind of problem with his mother, as he goes out of his way to say that she had "nothing to do" with his "personal choice" of going into radio.
By 1992, he either lives in or is vacationing in San Andreas, the setting of Grand Theft Auto: San Andreas. While there, he calls in to the conspiracy theory show Area 53 on WCTR. He says that while hang-gliding in the San Andreas desert (Bone County), he saw a man at a trailer compound performing strange rituals with a Domestabot. The show host Marvin Trill (who is later revealed to be the man that Adam saw) tells him to get a real hobby and hangs up.
