I've read the "pro and con" editorials in Radio World and some of the
other trade rags, but every single editorialist misses the following
point:

Sound quality is not the problem. PROGRAMMING is the problem.
We probably shouldn't rely on anecdotal evidence, but everyone I know
will put up with natural and manmade noise to hear their favorite shows.

Come to think of it, there's no evidence that DRM or IBOC have anything
close to a robust noise - fighting system. I imagine a good
thunderstorm
will cause dropped packets and receiver muting.

Another problem is multiple layering of compression and expansion
codec schemes. Has anyone listened to a (usually) decent - quality
AM plant that is transmitting supercompressed talk show audio
at a bandwidth of 5 KHZ with a low, low, low bitrate? Something
along the lines of 8 to 16 KHz bitrate? That fact alone puts the lie
to the digital pushers' rants about "Audio quality."

DRM - Deception Radio Mondiale

Another lie is the system is open and contains no proprietary
intellectual property.

It won't be any better under the best of circumstances where you will
trade noise and interference for drop outs.

DRM is a lame scheme.


Digital radio and television are lame schemes, period. To get the same
quality as analog, you have to have a much wider bandwidth in digital.
Encoding schemes are ways of narrowing bandwidth required to broadcast, but
they all have some trade-offs. I've not been impressed with digital
satellite at all. Too much weather related dropout, and too much
pixelization, especially during fast scene transitions..

At this end of the ocean the DRM consortium people really believe in a

AM to FM took almost 40 years, and AM is still on, the advantages to FM
over AM are more spectacular than DRM over AM in a world where also FM
is available and the most popular band.
Actualy DRM is ruining the AM band and I dont like the idea of one
broadcasting band with 2 incompatable modulation systems.
DRM only causes a lot of noise on your receiver and is already
irritating the audience.

Digital modulation might fit within the same channel bandwidth as an analog
channel, but it's obvious to anyone who listens that it has much more
interference potential. Analog modulation normally puts only a small
percentage of power at the ends of it's allowed bandwidth, and that power is
intermittant. Digital modulation puts as much power at the ends of it's
spectrum as anywhere else, and the noise is continous.

Glenn Hauser has been reading reports from DXers blasting DRM. Among the
most prominent of these DXers is Ralph Brandi.

If you want to demonstrate that you're an ignorant peasant then that's
completely up to you.

Yanks call Brits "limeys" because there was a shortage of limes on
British ships (about the time we decided to go over and create America),
so sailors died of scurvy apparently. But seeing as British people don't
tend to sail to America in wind-powered ships these days, don't you
think it's a bit of an outdated put-down?

Here's some more up to date put-downs:

* The American people voted George W Bush to be your president, despite
the fact that he clearly has an IQ that would classify him as being
mentally-retarded in the UK.

* You've got Jack Nicholson in his role as The Joker from Batman as your
Defence Secretary, and he's even keeping in character by getting his
underlings to do a bit of torture.

* You're all fat.

Is that your waistline?

When do you folks plan on repaying that WWII debt that you still owe us?

We could use the money.

No wonder Digitalboy


What are you calling me Digitalboy for? I'm certainly no cheerleader for
DAB, quite the opposite. Although I don't write off digital broadcasting
per se, like a few of you seem to have done in this thread without any
good evidence to back up your arguments.


claimed that most radio listeners in the UK
would migrate to FM if given the chance. 5 KHz must sound like
crap.


It does. Digital radio also sounds crap when mis-used, but it can also
sound very good if implemented properly.

True. Americans are also much bigger than Brits in terms of being fat

Now, why don't you go run along and play radio, Digital Boy?

If you're getting weather-related drop-outs, it means your dish
installation is inadequate -- not big enough, not pointing in the
right direction, or suffering from water penetration.

*very* interesting, Ruud - do you do any listening using
DRM yourself? I wonder how well DRM holds up
when propagation conditions are changing, or perhaps
during severe thunderstorms?

No, I dont have a DRM receiver, and I am not intending in getting one.
Now on DRM is 1296 "AM" with BBC world, copying 648 in analogue.
Since BBC W programme's are mostly speech based and the 648 TX sounds
excellent I really cant see the need for going to the shop for DRM
(Which is not there).
