Re: Hawaii shuts off transmitters today

- It's simply not economically practical to fully replicate analog coverage. That last 2-3% takes a greatly disproportional investment. Back in the 1960s it may have been worthwhile to put a translator in - you didn't have a cable system and two satellite services already providing your signal to most of that audience. (and providing another 100 or so channels to split the audience) We just don't the same TV landscape.
As I've said when I've brought up digital translators - that'll happen if the station determines it needs to serve that area OTA.
I've identified five areas here on the fringes of the Cleveland market likely to get difficult OTA reception even after the transition, in full-digital. Will any of the local stations decide it's worth it to put in a digital translator to serve, say, Mansfield and Ashland, on the southwest edge of the Cleveland TV market?
My gut feeling is right now, probably not. The bulk of the market will be served - as they always have been - by the facilities all of the local full-power stations have right now in the southern suburbs. The PBS affiliate in Cleveland (WVIZ/25) already has a couple or three analog translators up in places like eastern Lake County and Geauga County - I presume they'll get at least one of those sticks in digital at some point. But as I said, they already had them - and WVIZ doesn't make a big deal about it.
My other guess - at some point, some of these underserved communities (on the edge of digital OTA reception without major antenna help) may put together old-fashioned "antenna cooperatives" like they have out west...I know there are some of 'em in the Sierra Nevada mountains, owned by non-profit community groups, that rebroadcast the Sacramento and San Francisco stations.
In other words, none of this is gonna spring up on its own...either the stations or the locals will have to feel the need is great.

- TV is a poor choice for emergency alerting. Chances are pretty good your set isn't on when the emergency happens. (this is why I think the famous Clear Channel/Minot, ND incident is a red herring*. So what if all the Clear Channel stations *had* immediately broadcast the emergency alert? How many people were listening to the radio (/watching OTA TV) at 3am?)
Minot is a small city. Very small. I was actually there once, in late fall/early winter, stuck in an Amtrak station because our train's locomotive needed repair ("Empire Builder").
If the emergency authorities wanted to get the word out about danger quick, instead of wasting time trying to raise a live body at the radio station, they should have driven through the streets with sirens and bullhorns. That doesn't absolve anyone from not being responsive, it's just practical, and of course, from what I've heard, the local police/authorities/whoever did not know the proper procedure for activating EAS, which WOULD have gone out on the unattended stations. (Think: NWS! And speaking of which...)

This is what the NOAA weather radio network is for. The radios are specifically designed to operate 24/7 and only alert you when something happens.** IMHO leaving analog TV on the air does almost nothing to improve public safety.
Congress and the incoming administration should concentrate on two things if they're really worried about public safety notification - 1) allow the option to use the DTV $40 coupon to help pay for a weatherradio and 2) expand the NWS network of radio stations as much as possible to serve areas with trouble getting DTV signals.
Makes too much sense.

- I'm with "OhioMediaWatch", about the relative quality of analog and digital reception. I enjoy DXing in analog, but when I want to watch a program it *will* be watched in digital. (especially on the 4-2 and 8-2 subchannels that aren't available in analog!)
And the 3/5/8 combo of network affiliates has become even more difficult to watch in analog here since I was a kid. The man-made electrical interference in 2009 is off the charts, particularly on 3/5, and I'm 20 miles from the Parma TV antenna farm.
And same equipment, same antenna, same location...watching in digital is crystal clear with few problems. I realize YMMV for others here, but that's my own experience.
