For One and All,

Here is "Why" I am 'skeptical' about Digital Radio Mondiale
(DRM) and In-Band On-Channel (IBOC); and will continue to
buy a a few more radios in the next Ten Years (10 Yrs) that
simply offer normal 'analog' AM/MW, FM and Shortwave Broadcasts.

"iBiquity Digital designed its IBOC technology to bring

Radio while preventing interference to the "host" analog

For the most part TV is an Every Family (Household) and
Every Family Member (Everybody) Broadcast Media Activity.
[ Everyone Watchs TV 3-5 Hours a Day Every Day ]
TV is "The" Mass Market Media in the USofA [.]
..
Contrast that to Shortwave Radio; where One Household
in Ten in the USofA and 'only' One Member of that
Household (One-in-Three) may be a Shortwave Listener
(SWL) and 'want' DRM and IBOC. This is a limited and
specialized Consumer Market with small Profit potential.
Likw AM-Stereo this may be a Product the the Consumers
"Do Not Want" {Feel They Need}.

IN-THE-NEWS :
So here is the News Article that got me to start Thinking
and Writing this post. It is about the the near term
future (2-4 Years) of Digital High Definition TV (HDTV)
and related Technologies and Products.

The good news from this year's Consumer Electronics Show
is that companies manufacturing the latest television models
have finally learned to make some of these sets fit into
ordinary budgets. - by Rob Pegoraro, The Washington Post
..
MY-POINTS - About High Definition {Digital} Television HDTV :
..
* It's coming and will become the 'standard' for most
American Households but not for the next few years.
..
* The Commercial Forces behind it are Great because
there is Big Money to be made selling the 'new' TVs.
..
* The Consumer Demand is 'growing' and as TVs wear out
more and more of the replacements will be HDTVs.
..
* Since most 'analog' TVs still have a "Picture Tube";
I would expect that a TVs useful life would be 3-7 Years.
..
* While our AM/FM Shortwave Radios being fully Solid
State should have a useful life of 10-15 Years; barring
a user caused 'accident'. (Or the Urge for a New Toy.)

This line of thinking is a little more on target. To follow the
"pipers" is to skip merrily over the cliff's edge. I'm not going to give
anyone the bullets to shoot me with. If it ain't broke, don't fix it.

What you have pointed out is one of the reasons IBOC is being pushed to
begin with - they want to attract more listeners = more money.

In regards to SW DRM, I can only surmise that the "digital" may attract
more listeners but the advertising dollars are not interested in an
international audience.
Unless DRM is designed to create more local and regional listeners which the
advertising
industry may respond to.

If the industry can't attract more listeners then the MW & SW will remain on
track to become the dinosaurs of broadcast media. Whatever the final
outcome may
be - Long Live Analog!

I don't know about MW, but SW has been a dinoaur in Western countries
for decades now...and I wouldn't have it any other way. That's
precisely what's kept it interesting all these years.

I agree! Less flame-thrower interference also.
Maybe one day we will experience the bands as they were before the cold war
and proliferation of high powered SW transmitters.

Nope. As soon as the HF users reach a certain level of decline,
the FCC will auction-off the HF band for use in WI-FI local
broadband networking, telling the hams to enjoy "2 meters and down."
Count on it.

1. DRM

DRM is a European solution to a European problem. It's a system
that a bunch of second tier broadcasters have come up with to
use their existing frequencies to continue to be continent wide
broadcasters in the face of the various national broadcasters
conversions to local digital radio systems.

2. IBOC

The US National Association of Broadcasters method to jam adjacent
(out of area) signals and restrict the possible number of stations.
On a local NPR station's program about their conversion to IBOC, one
of the particpants admitted that the reason that IBOC is being pushed
was that other systems could double the number of stations and that
was unacceptable to the NAB.

3. Cost

Both of these systems need a digital signal processor with a hundred
million instructions per second or so of throughput. That sort of CPU
power is going to cost in both money and electrical power consumption.
That means about $100 more than an analog radio and a hard time to
make a portable that doesn't suck batteries like no tomorrow.

The IBOC promoters seem to think that people only listen to the
radio in a car, too. Well, maybe that's the only market that
will spend the $$$ for the equipment.

I hear that the IBOC digital CODEC (compression scheme) is lousy
for voice. Just what the talk radio people need. ;-)

IBOC and HDTV have the same problem. I'm gonna be damned if I
will spend several hundred bucks for a new radio or TV if it's the
same crappy programming as I get now.

It would have to be the U.N. that holds the auction as SW is not a "single
country" phenomenon.
In which case you can expect it to be riddled with FRAUD!
