Lord knows, Maybe Cox is paying very little attention to there HD stations. Maybe something happened to the transmitter and Cox figures nobody listens or has HD Radio anyways. Its a shame that the HD2 isn't rocking out anymore. Given the only other alternative to 96.5 HD2 is JRR. The HD stations that Cox does have are running on playlist from 3 or more years.
CBS seems to push the HD Technology the most, with all of the ad's I've heard to buy HD Radios on Q105 and such.
