I have never tried HD radio. I think 107.7 is one of the first stations to try this. I agree, it is a very cool station. Even though it is stateside, it supports a lot of Vancouver indies. Plays a lot of bands from Portland to Vancouver.
You think Vancouver radio is bad, you should hear Calgary's radio selection. 5 stations, all playing Red Rider (80s Canadian bland rock). Thank goodness for internet downloads.
