    • Jean Lavoie
      I think it is a good radio of Peterborough, with music, news, contests, and sports. But sometimes I wish the hosts were more witty.
    • Lana Kelly
      I am from Peterborough, and want to say thanks Freq 90.5. I like your alternative rock format, especially love hits from the 1990s and 2000s. And contests that you hold. Would like more a local shows.

      John Badham was a great host of that radio, when it was called as Extra 90.5. But I still love this Peterborough station with its sports play-by-play.
