Kiss legend David Rodigan has quit the station after having his radio show shunted to a midnight slot.
The broadcaster leaves the station after 22 years championing reggae music and claims that his choice to depart is because he hopes to make a stand for the genre.
"Due to their continued marginalisation of reggae music into the twilight zone of radio scheduling, it has left me no option but to make a stand for my passion and the music I love so dearly," he says in a statement.
"I've been with the station for 22 years, shared some wonderful times with many fantastic artists and members of staff, and it's with great sadness that I've come to this decision."
"Reggae was originally played on the streets, not on radio, and Kiss's refusal to schedule the only reggae show on their network to a socially accessible time has resulted in this decision. Reggae is worthy of more respect and so are the fans and lovers of this music."
Kiss spoke of their sadness at the loss of the DJ known affectionately as Ram Jam, saying that he leaves the station with their 'appreciation and gratitude'.
