Element9 said:Scott, I'd be the last one to question your sincerity, gravitas or background as they apply to broadcasting... so I won't pose this post in that manner. I will however, offer that HD is a universally flawed technology for Amplitude Modulation. Its negatives outweigh any positives in this regard and as such, HD appears to do more harm to "the neighbors and neighborhood" whose yards are being vandalized by the HD lawn treatment.
Wait till you read what I have to say about it in the NERW year-in-review/year-end rant, coming to a fybush.com near you in a few hours...
As to HD being a tool for non-com AMs airing on FM sisters' subs, this benefit may be temporary. Streaming combined with WiMax and WiFi may be better alternatives with greater possibilities, i.e., reception and acceptance, especially among the lower demos so desperately needed by all AM and FM stations.
And indeed, WXXI, like pretty much every other public station in America, is using streaming as another tool in the arsenal. But it, too, has its drawbacks: even if the dream of universal WiMax becomes a reality (and I'm somewhat skeptical at the moment), it still puts some burdens on both listener and broadcaster. Think your Verizon Wireless/AT&T/T-Mobile bill is high already? Wait until they start dinging you for all that mobile bandwidth at your end.
As for the broadcasters, WXXI does its streaming in-house, and the costs to serve up all that bandwidth don't scale up nicely. The FM HD signal, on the other hand, costs exactly the same to transmit whether one person is listening or whether 10,000 are tuned in - and once those listeners have paid the relatively minimal (as little as $50, when there's a rebate offer going on) buy-in cost for the radio, that's it. No monthly fees to your ISP or wireless provider...you just turn the thing on and listen. Kind of like...what was that thing called again? Oh yeah..."radio."
listener-in, meanwhile, suggests:
The cost of an HD radio is comparable with WiFi but in expanded listening options, HD cannot begin to compare. I don’t think HD can support itself in the long run as an orphan technology with users largely confined to the public radio audience. I would guess that if the powers-that-be at WXXI had known then what they know now, they would never have considered launching their HD service.
I'm not a "power-that-be" at WXXI - indeed, it should be noted once again that I speak only for myself here and not for them. But that said, I don't think there's been much, if any, second-guessing of the decision to put HD on 91.5. The WXXI-FM antenna needed to be replaced anyway (it was the original, beat-up RCA antenna from the station's sign-on in 1974), and so the incremental cost of adding the HD signal as part of that project was minimal. (The ongoing cost is pretty much limited to the power bill for the HD transmitter, and at 450 watts ERP, I'd bet we're spending less to run it than we pay in the power bills alone - never mind the bandwidth costs - for the streaming audio servers!)
I'm not privy to the exact numbers, but it's my understanding that the addition of the HD has yielded not only new listeners, but new membership dollars, in areas that couldn't hear the AM signal on a reliable 24/7 basis.
It's hard to believe for some of us who are plugged in 24/7 (as I suspect most of us on the boards here tend to be), but there's a fairly sizable audience out there that's not already subscribing to high-speed internet (at $50+ a month). For them, the choice between a new HD radio, at $100 or so, and starting up with WiFi radio from scratch (figure $50+ for a router, $200 or so for the WiFi radio itself, and then $600 or so a year to the ISP) is not as much of a slam-dunk as you'd seem to think. Sure, there are thousands of new listening options available with the WiFi radio - but if the goal is simply to be able to hear Bob Smith, the local news headlines, or Marketplace, sometimes the simpler solution is the better one.
Will HD end up as an orphan technology if it never takes off in the world of commercial radio? I suppose that depends on what constitutes an "orphan" in a world where one could, if one really wanted to, build a brand-new AM stereo plant, 20 years after that technology lost whatever buzz it might once have had. There are more (and better) HD receiver choices available now than there were a year ago, and every reason to expect that our Harris transmitter will be supported for a while to come.
It's reasonable to think that the life-cycle of any new broadcast technology is going to be far shorter than the 67 years we got out of NTSC television or the 90 years AM radio has provided. As I've said before, I don't think WXXI (or public radio in general) is in the "HD Radio" business, but rather in the business of providing valuable content to listeners by whatever means are most efficient and useful. When, at some point down the line, HD ceases to meet those goals, or if something better and cheaper comes along, it will go away and be replaced by whatever comes next.
In the meantime, it's one relatively inexpensive tool in a growing arsenal, and I don't sense any regrets over having chosen it or any sense that it's going away in the near future.
