I may have missed this in the forum somewhere, but when the switchover to digital TV occurs, will the 996 be able to receive the broadcasts? While I'm driving to work, I will sometimes tune into the local TV broadcast on the search mode so I can hear the news and weather.

Thanks!

No. Digital TV Audio cannot be decoded by any scanner.

No, AM/FM car radios don't carry TV signals.

It never hurts to read a post twice if you get confused.

BCT 996 and "Digital" TV Channels

I would also like to be able to receive the audio portion of ATSC channels, but even with the correct tuning ability, it will not work while in motion. I did an experiment several months ago because I wanted to see it and hear it myself. I took one of my Zenith DTT901 converter boxes and connected it to my wife's Dodge Grand Caravan, which has a built in DVD entertainment system. It also has a 12 volt DC to 120 volt AC inverter, so it was pretty easy to hook this up. The channels were already scanned in, so I simply connected to AC power, attached an antenna, and plugged into the input on the van. While I was, parked the signal looked pretty good. I then took a drive. While the van is in drive, the video is disconnected, but the audio still passes through. I went on a pretty straight southbound highway, but almost as soon as I was in motion I lost audio. Sometimes I would get brief snippets of audio, but when I stopped at a traffic semaphore the audio was solid again. I am in my work car almost the entire 10 hour day each work day. I don't need to have TV audio all of the time, but it is nice to have during local news broadcasts. I have in my pickup truck an AutoTalk converter that allows me to hear the audio from NTSC (analog) TV. Needless to say it won't do me much good pretty soon. Granted, there will still be some low power analog broadcasters, but not much of it will be of any interest to me most of the time.

There is an ATSC Mobile DTV Standard coming down the pike, however. http://www.broadcastingcable.com/article/CA6618009.html
In the meantime you could get by for now by tuning into IFB frequencies:

VHF: 161.640 161.670 161.700 161.730 161.760 mHz

UHF: 450-451 and 455-456 mHz

Oh, wait a minute, we made that illegal to listen to at the same time we banned listening to cell phones. Nevermind.

Actually I recieve tv channel 6 WLNS very well on 88.1 on the FM dial.The frequencie of channel 6 is 87.75 mhz is so close to 88.1 that the radio recieves it,I even have a preset for it. Assuming a BCD996T tuned to 88.1 recieved the the same signal what would stop it from decoding it if it was digital,that is assuming the tv stations are using the same frequency when they switch to all digital next month.

When we switch to digital, we 1) abandon the old frequencies and 2) switch to digital instead of analog signals. So even if you tuned in the new audio frequency (400's I think?) you couldn't hear it.

So definitely not on your AM/FM radio anymore, sorry.

You may catch some analog news remotes or live event feeds in the 160MHz range. Just use the NEWS service search. Interesting off mike comments at times.:cool:

You sure?

Many stations will be staying on the same frequency assignments.
Not that it will help in this situation.

I think the original intent of the AM/FM suggestion was to listen to a radio broadcast of the news and weather...

Since the thread specifically is about TV broadcasts on FM stations, I'm not sure I get the connection.

NJ - we are changing channels (nobody turned in the paperwork to keep 6) but I'm not sure that audio frequencies are staying the same anyways? I have no idea though, but as we've noted, it doesn't matter since your FM radio won't convert it.

Not sure the thread that I saw it in but somebody indicated that the audio is encoded in the same stream as the video for DTV, not like on a separate freq like analog so you would need to decode the whole thing to get the audio out of it.

To which AlabamaRS replied:
just use the am/fm in your car???

The connection is that there is plenty of news and weather available on broadcast radio that can be easily tuned in to.

Not around here... We only have one local radio station that does news, and it's rarely updated. The era of full-time news radio stations has ended for most of the country.

"While analog and digital television broadcasts have a modulated carrier wave, the way that signal is modulated is quite different. Analog TV uses an amplitude-modulated (AM) signal for pictures and frequency modulation (FM) for audio, while DTV signals use digital "packets", or bursts of data, to transmit pictures and audio."
