1. WXXI - or any TV station - doesn't HAVE to keep the analog transmitter on. A number of stations across the country are shutting down analog simply because of the cost.
Not true, the FCC is actually denying some TV's applications to shut down before the new date in June. Mind you, stations had to submit applications to shut down and they had less than 72 hours to do so after the announcement went out about it. And that 72 hours was over the weekend. Whatta mess. In deference to WXXI, I do believe that all the non-commercial stations were automatically granted the right to shut down immediately if they got their application in. FWIW, I don't know if (for engineering reasons) another station has to shut down in order for WXXI to fully move to digital...I don't think there was a frequency shuffle like that in their case, but I don't know for sure...no doubt Mr. Fybush does.
Ultimately I think WXXI opted to maintain analog operation for marketing reasons, though; the audience most likely to be affected by the analog shutdown is also the audience that tends to give the most money, watch the most, and complain the loudest when things change: the 54+ (and the high end of the 25-54) demo. I'm sure they'd LOVE to just pull the plug and save the money, but after the news went out about how the guvmint extended analog a little longer, I'm sure a lot of viewers would bitch and complain if WXXI shut down "early".
Granted, many of those viewers will bitch and complain anyways...and they'll refuse to get a converter box until they're forced to do so. But if WXXI waits until the FCC-mandated deadline, at least they can redirect the wrath towards the FCC instead of themselves.
As far as local radio is concerned, public radio may be the last bastion of reliable news coverage.
And local newspapers for that matter. There's a rapidly-growing movement in NPR to encourage local affiliates to pounce on the "opportunity" presented by local newspapers being flushed and swirling; in many communities the NPR affiliate may be the sole remaining source of local, independent news.
Couldn't all or most PBS/NPR stations just run all the network programming off the birds in an austere building at the transmitter site and from a local angle, just have a skeleton staff of a few dedicated staffers of on-air people, engineers, office staff and one manager?
It can easily cost $30,000 per MONTH to operate an analog transmitter. Presumably digital isn't all THAT much cheaper. Plus tower rent, studio rent, etc etc etc...and programming fees (which are hefty). You can't raise those kinds of funds on a skeleton crew. And even the skeleton crew you describe would mean a quarter-million in salary costs alone (and that's if everyone comes very cheap).
Radio, OTOH, can - in theory - operate on even less than a $30k a YEAR, not including programming fees, if the tower happens to be located, say, on campus. Mind you, a $30k/yr annual budget is a disaster waiting to happen, but it can sort-of be done.
