Impressive!

Ever had a forecast for your area go bad?
For example, today in Grand Forks, they were calling for breezy conditions and mostly sunny skies...but this afternoon skies turned quickly overcast and we've had snow showers on and off all day.
Failure means that things can be fixed for the next time.

This was just a test to see what would happen with a first ever nationwide EAS activation over all possible media outlets. The NWS was purposely told not to do a routine weekly test today so that everything else besides the weather radio was tested. I even sent out that statement about it for my office a week ago. Obviously, the feedback from this test should hopefully push for significant improvements. The long-term goal is to have a completely digital EAS so that all platforms like cell phones, pagers, and the internet itself along with the traditional outlets of TV, radio, and weather radios can receive these critical alerts.
This actually leads me to a question I've always had in mine. Why is it that the analog feed starts EAS tests (weekly or monthly) earlier than on cable? Also the same thing when it comes to programming in general.
This has an easy answer.
Analogue transmission is output on a TV or radio as soon as it is received, because it is transmitted by simple means: modifying the amplitude (AM) or frequency (FM) of the radio signal. This is a real-time process and is reflected by the means of output (TV or radio) by being repeated in real-time.
Digital transmission, however, is in packets of digital information, which are essentially meaningless until they are decoded by the TV or radio. Therefore, what's being broadcast must be encoded from the broadcasting facility into these digital packets, and then must be decoded by the TV or radio as they are received. This process takes a little bit of time, hence the delay as compared to analogue.
Nationwide EAS test: FAIL!
I monitored three sources: a local broadcast network on cable, a basic cable network, and a local radio station.
The local broadcast network activated the test, but the audio quality was terrible to the point of incomprehensibility. The basic cable network did NOTHING. And the local radio station sounded the warning tone, followed by absolute silence until the end-of-alert tone.
Had this have been a real emergency, the it seems like many people wouldn't have heard it.

A hurricane in Alaska?
What Tavores probably meant was Hurricane Force Wind Warning.


I'm not sure how much different (internally) the IS2 is from the IS, but it doesn't seem like it should be this problematic. To me, it seems like it's very unstable or some of the units are defective.Think of it like Microsoft deciding that instead of building Windows 7 on top of Vista that they would start from scratch and use no code from Vista. The hardware and software are completely new here. Not to mention this is the first product of its kind to do this in HD. With the XL and IS at least there were some similarities. I would imagine the XL and first IS versions were just as problematic
