and with only 60% the coverage of analog.

Using 1/100th the power of the equivelent analog's signal carrier. Thus
a
power savings to the station.

And, as discussed, on FM the "used" coverage area is the 64 dbu curve.
Over
80% of listening is in the 70 dbu, and the rest in the 64 to 69 dbu
contour.

The HD signal at least matches the 64 dbu useful and used contour. On AM,
the HD signal is often listenable beyond the "used and useful" contour of
the analog signal.

HD/IBOC causes adjacent-channel interference and has only 60% the
coverage of analog.

There is a difference between arbitrary signal contours and a usable signal.
The FM HD coverage is about the same as the usable, useful FM analog signal,
and in noisy markets, the AM HD in some cases extends beyond the usable
analog contour, especially at night if the protected contour is a high
value.

HD's channels are low-bitrate streams

The station has a certain digital HD bandwidth that they can utilize as
they
wish. They can allocate the full HD bandwidth to a single channel for the
best sound. On FM that would result in a CD quality sound. Or they can
divy
up the bandwidth into 2 or 3 channels for lesser quality sound in each
channel.

of the same repetitive programming

If a station chooses to transmit two (2) HD channels, and many do, the
second HD channel's programming (HD2) is unique while the first HD channel
is the superioir sounding digital version of the analog signal broadcast.

Digital is digital - there is no static, noise, interference or fading
whatsoever on HD radio.

and with only 60% the coverage of analog.

HD/IBOC requires much more power than alaog broadcasting - you lose !

Nope, it is a fraction of the power. A 50 kw AM uses a 500 watt HD signal on
the same frequency

And pumps out 50kW of QRM!

In any case, HD sounds far better than any analog signal. HD radio
stations
will abandon analog and redirect the full station power of their
amplifiers
towards the HD digital stream.


Indeed. I just checked at www.hdradio.com. I had no idea there were so
many HD FM stations in my city (6). All have a 2nd channel also, so this
makes 6 new stations in my city!

I'll certainly be getting a HD radio this year, and I don't understand all
the opposition to it in this group. Is it just a case of old
farts/curmudgeons opposing something new? I *really* don't understand the
idea of clinging to what is essentially 100 year old technology - analog
radio. Are some of you lamenting the death of incandescent light bulbs
also?

HD radio will happen much like HD TV did. Prices will drop until Critical
Mass is reached, then it will take over. Once you see HD TV, you realize
how bad the old system was.

They'd better get some HD listeners before they do that, elsewise their
listeners will abandon them.

A low power, 9mm HD single chip decoder that uses 10% of the power of the
current chipsets headlines Radio World this week. Using this chip,
portables
are now possible with long battery life and the price point comes way
down
due to component materials. This is the evolutionary development we were
waiting for that will make receivers better and cheaper.

HD Radios will never sell.

Ah, Wal-Mart put the first HD radio on sale this week. The momentum is
building, and will continue over the next several years.

The only momentum I see building is the number of posts you make on the
subject.

LOL ! :-)

"The decision has no impact on news and talk stations who stream."

Besides, the laugh is on you since this will put the nail in analog
radio's
coffin.



Today:

HD Radio's latest score - Wal-Mart, in nearly 2000 stores.
Wal-Mart will begin by stocking the JVC HD-W10 Mobile receiver for about
$190 - and you can expect to hear spots promoting the new tie-in on HD Radio
Alliance member stations. Alliance chief Peter Ferrara says "Wal-Mart brings
HD Radio to an incredible new level of reach and power."

So Wall mart is gonna change AM radio. Give me a break.

Leave it to Wal-Mart to make QRM affordable.

It ain't QRM/N if nobody hears it.

I hear it so it "is" QRM.

Damn, that's some fantasy world you live in.


Nah, just reality. Creating interference to stations that get no listening
in the interference zone is a small price to keep terrestrial radio
competitive.

Excuse me, I hear it and it interferes with my reception.

This is pure baloney. Same crapola the DRM crowd tried to pass off on

It trashes my reception. Is that so hard to understand?

No, it is likely nobody can. But HD is being sold mostly to listen to FM.
