What is the new station coming in on 99.7? I think citadel is going to run it, not really sure. If HD radios were cheaper and in cars standard, the secondary channels are very unique. I like when a new technology first comes out cause they always run it on auto-pilot, just play whatever, sort of like back in the day when on digital cable all the special VH1 & MTV music channels would just show videos in that genre all day. Now since digital cable is more mainstream, they started adding the usual commercials, reality shows, movies, etc. Then back away from the videos only.
Right now HD 2 subchannels are great just music, no consultants ,it seems just piling a bunch of songs (some not usually heard on regular radio), with occasional radio drops, and that is it. In a couple of years when HD more mainstream those HD2 channels will start sounding more like their HD1/analog signal.
