That's not the case. The digital switchover doesn't have much to do with HDTV (high definition TV). All the switch means is that there will be no analog signal for a tv to pick up any more. Of course, you can always pick up an analog to digital converter for those tvs that still pick up an analog signal.

Amanda said "I will lose the audio portion on my radios"

You won't lose anything from your radios. Radio signals aren't affected.

I believe Amanda was using the analog HD signal to listen to certain TV broadcasts of her favourite shows/sports events on her radios and worries that because there will be a digital switchover, her analog broadcasts will no longer be available.

This is a serious case of confusion on everyone's part, and the industry is to blame. Here's Amanda's question, reworded:
Q: In February when the TV's are all converted from ANALOG to DIGITAL (Standard Definition digital and High Definition Digital), I will lose the audio reception of ANALOG TV CHANNELS on my ANALOG radios. One is on the kitchen counter and the other is for walking. I hate to lose the audio portion OF TV BROADCASTS and definitely do not want a TV set or satellite radio. Is there an AM/FM radio available with DIGITAL TV audio capacity? I've looked and looked but only find portables in England, which has a different electric system and prototypes in Japan. I hate to give up the audio portion of the TELEVISION news programs and ballgames.

A few notes:
*Analog TV will be turned off in February (barring delays by new administration
*TVs, VCRs, radios, anything that used an analog tuner (NTSC format) will no longer receive broadcasting.
*Newer TVs, VCRs, etc. with digital tuners (ATSC format) will receive the new digital broadcasts.
*HD Television is high definition television (720i/p or 1080i/p signal) broadcast using a DIGITAL signal.
*HD Radio HAS ABSOLUTELY NOTHING to do with HD Television (http://en.wikipedia.org/wiki/HD_Radio). HD doesn't even stand for High Definition - it's just a brand name, designed to confuse consumers. You will NOT get any (HD or SD) digital TV broadcasts on an HD radio, or on any current radios. You will need to wait until radios include ATSC tuners. Just like there were very few radios before that let you listen to TV stations, this will likely continue with digital TV.
Unlike AM/FM, which is a public standard, HD was created and closed off by ibiquity, and sold to a bunch of radio stations, and is a monopoly. This is why HD Radio tuners are still expensive, and you can't build an HD Radio out of a kit like an AM/FM radio.
HD radio broadcasters are just existing radio stations that happen to broadcast in both FM/AM and HD. Not every station has HD Radio, and the content isn't always the same on FM and HD. HD also allows one station to broadcast multiple streams. HD Radio gives you CD-quality sound for FM stations, and FM-quality sound for AM stations.
If you want TV in the kitchen, you could go with something like the Audiovox VE727 DTV/AM/FM/DVD unit, which is an under-counter mounted AM/FM radio with a 7" LCD screen and a DVD player, but it does include ATSC (digital) tuner. ToysRUs may have them for $100 (see http://forums.slickdeals.net/showthread.php?t=1118859).

I forgot to add:
Yes, it is true, you can buy a converter box for $40-$60. This will NOT give a you a high definition signal, only standard definition over digital. You could plug the converter box in the kitchen (if you had an antenna), but how would you hook it up to the current AM/Fm radio if the radio does not have an AUX input? You also can't take the converter box jogging with you - no AC jacks in nature, are there?
Ironically, High Def TV tuners have been reduced to the size of flash drives, but no one has figured out how to package them into small radios yet.

One more note: Cable and satellite service will continue to work with no interruption - only devices that rely on an antenna to receive a signal (like Amanda's radios), and don't have a digital tuner, will stop working. Cable and satellite service, especially when used with a set-top box, don't need a tuner in your TV (unless you are watching them on channel 3 or 4), and even analog cable service (delivered without a set-top box directly to your tv) will continue to work as before until the jerks at the cable companies move all the analog channels into digital. Once cable goes all digital, you'll have to use a set-top box, or have a TV with a CableCard or true2way support built-in - digital cable will not work on just an ATSC tuner.

Man, I'm just getting more confused reading the explanations about all this. Let's just see how our elders deal with this, shall we?

I think that maybe (and I mean maybe) Amanda meant to say that she has a radio that also happens to pick up UHF/VHF audio signals. That kind of radio is a bit of a rarity, so if that's what she has, I wish she was more clear about it.

Also, it would have been helpful for her to say what types of inputs her radio has. If she has the correct type of inputs, I would imagine that a cheap converter would fix her dilemma. It would help everybody if she listed what radio she actually has.

Also, I don't think this is a matter of the industry deliberately trying to confuse customers. The government has never said that for the switch you need an HDTV or you're out of luck. HD radio makers have never claimed that HD radio delivers TV audio channels. However, people keep making those unfounded assumptions. She's also making the assumption that satellite radio might be her answer, but it's probably not that way either.

Bravo LAArt. Beautifully explained, thank you.

My little 20 year old battery powered tv will stop working as well. It came in handy during Ike.
