I predict that at some point, Radio One will move the gospel off of the 92.1 HD channel to another Houston property so they can kill HD on 92.1 for better signal coverage. I can't tell if 92.1 still broadcasts HD or not, but the website for Praise Houston calls it Praise 102.1 HD2 so maybe its already moved.
92.1 never turned on its multicast.
Praise has always been on 102.1 HD-2 since the format changed on 92.1.
News 92 still runs its HD. Turning HD off doesn't help your analog coverage.
