Karina — Y107

I need to verify if there is a known radio DJ named Karina at Y107. A quick search might help, but since I can't do that, I'll have to rely on existing knowledge. Alternatively, maybe "Y107" refers to a show or a specific event. Wait, Y107 could also be a radio station's call sign, like in the US for example KROQ-FM in Los Angeles has a sister station called Y107, which is KROQ-FM's classic alternative format. But in the US, Y107 is a real radio station. However, the name Karina isn't a well-known DJ there.
