I think they made the announcement yesterday the Stros will be broadcast on 790...so I ♥ Radio would work
I may be wrong but I believe Lunatic is right. The Rockets games are broadcast OTA on radio but are not available over the Internet without purchasing the NBA League Pass package. I have tried listening to them over the Internet but could only get the pregame and postgame shows. MLB operates the same way in that you will have purchase an MLB.TV package for $109 or $129 to get games via the Internet.
Couldn't find anything about MLB radio. Found this however: http://mlb.mlb.com/mlb/subscriptions/index.jsp?c_id=mlb&affiliateId=networkmenu But I do recall something about getting MLB radio games this way. They may have dropped it for their premium video service.
I can't imagine them dropping radio. I've had it for several years. I think I'll ask for MLB.TV premium for my Bday this year anyway. That is a good value, IMO. Found it: http://mlb.mlb.com/mlb/subscriptions/index.jsp?content=gameday_audio&affiliateId=mlbMENU
