They have to pay iBiquity to have any HD sub channel aside from HD1. iHeart shut all of theirs off except ones that feed translators, ones that simulcast AMs and some others like 95.5 HD2 and national feeds like Pride Radio.

Audacy followed lead. They shut them all off except for national feeds like Channel Q.

WXRT HD2 was the exception in Chicago. They must have shut that one off very recently because it was on the last time I checked. It is off now
