I'm just voicing an opinion here, so don't take anything I say as factual.
WXRV has a reputation for not tossing money around. Between the equipment, the licensing fee to Ibiquity, etc. it is not cheap to go into HD radio.
WXRV also has seen how well HD Radio has been accepted by the public.... even someone like me who likes his electronic gadgets didn't jump on the bandwagon. I did look at putting HD in the 2 Ford vehicles I bought in the last 18 months, but opted not to do it. I didn't put XM in them either, but that is another story.
Now there are people who really like HD, especially the extra programming. My wife has a co worker who brings his IPhone to work and uses the HD app and really gets into it. Personally there is nothing HD is going to give me that I can't get from XM's online streaming if I am at a desk.
Until the public starts buying HD radios, or the feds mandate them, or they force analog off the air, there is no incentive, or enough return on investment to justify the equipment or programming costs. The big players in the industry who spent the money and are paying to program the HD2 and HD3 in some cases would in retrospect rather have that cash in the bank right now rather than having it poured down the black hole that is HD
Talk to me when HD gives me 5.1 or better surround sound in the car. I know WZLX has sent much of their library out to me remastered in 5.1 and one ZLX staffer who posts on this board has mentioned it sounds great in the air studio.
Until then, HD Radio and IBOC are dismal failures, doomed to go the way of AM Stereo and Quad FM
IMHO, YMMV.
