The local community college has(d?) a good rock station with no ads but I am just out of range of their transmitter since we moved so I have not been able to listen for the last couple years.

In the US, the HD stations also don't play as many or any ads, I don't know how they are funded but its pretty cool. Mostly deep cuts or out of vogue genres. There are a couple of cool local jazz, blues, oldies or others.
