Don't bother. DRM is to shortwave what one of these cheap Chinese-made
set-top DTV converter boxes are to your grandmother's 28 year old
floor console RCA TV set.

"Why don't you use DRM on Shortwave?"
"Some large companies are pushing DRM by convincing program producers
and broadcasters to start airing in DRM ahead of time, but unless
there is mass availability and penetration of receivers on the
listeners side, this will remain - unfortunately - a technological
experiment, and broadcasters using it to reach their listeners now,
are clearly throwing their money out of the window."

DRM on shortwave is dead - wow, only two very expensive receivers...

There are no portables I am aware of due to the power requirements of
DRM but it looks like there may be some models in the near future.
Example <http://www.universal-radio.com/catalog/portable/0023.html>
One thing that makes me leery of purchasing a DRM receiver is the
firmware is a compilation of licensed software. The software agreements
can change and you have no control over it.

There are natural application for DRM on the Shortwave
Radio that would give it a new life and a leg-up on a
future . . .

DRM = Digital Radio Mondiale

.
Actually for a Medium Range High Frequency
Broadcast Scheme DRM has a natural 'fit' for
a US Military application in the AFN Shortwave
Radio Broadcasting System to specific Ocean
Areas from localized Transmission Sites.
.
Replace the AFN Single-Side-Band [USB] Signal
from Shore to Ship with a Digital DRM Signal that
would have better Audio Characteristics and a
'potentially' more consistent and stronger signal.
This Upgrade of the AFN Shortwave [HF] Radio
Systems only requires new DRM Transmitters at
the Four Key Transmitter Locations and and a
single High-Quality DRM Receiver in each and
every US Navy Ship. Minimum Cost and Big
Impact ofr the US Navy and DRM as a Shortwave
[HF] Radio Broadcast Medium.
DRM is an Out-of-the-Box Upgrade of the AFN
Shortwave Radio Broadcasting System for the
US Navy that requires little development cost;
one time major investment and very little change
in the oprational costs of the present system.

DRM - The Signal Quality and Distance Factor :
Is there a Natural Problem Beyond the Limits of Technology ?
http://groups.google.com/group/rec.radio.shortwave/msg/2e26a8f66140d5e0
.
DRM as a Broadcast Media seems to Work Best
out to 3500 km ~ 2200 Miles which is a Natural for
the AFN Shortwave Over-the-Ocean-Area Broadcast
Scheme.
http://groups.google.com/group/rec.radio.shortwave/msg/cbed7bc429af3132
.
The Digital Radio Mondiale (DRM) Signal seams to work
best as an 'intra-continental' Domestic Broadcast System
with a Range out to 900~1200 Miles.
http://groups.google.com/group/rec.radio.shortwave/msg/e8b553514d5c72d7
For AFN Shortwave Over-the-Ocean-Area Broadcast
Scheme DRM could easily be very effective out to
1800~2400 Miles.

audience for SW broadcasting from the big countries is poorer areas in the
world who barely can afford a simple SW radio, let alone a DRM radio that
will cost more than a year's salary there. Could you imagine listening to
Ralph Stair on high-def radio??????

DRM - To some in Business and Government
the word "Digital" Means everything 'futuristic".
The only way that DRM really gets off-the-ground
is for the Broadcasters to support {subsidize} the
Price of the DRM Stand-A-Lone Receivers.
* Low Power DRM Chip-Sets
* FREE Plug-and-Play DRM Radio Softwave

In 10 years time most receivers will be SDR (software
defined receivers). Then DRM decoding is simply a matter
of choosing the right software. Look at WinRad.

Disagree, not with shortwave. If anything, people will keep moving to
satellite radio, WIFI radio, and like minded stuff. Shortwave is desinted to
remain low tech, as it should. They may flirt with DRM and such but it won't
stick with shortwave. There's no way the broadcasters who already have very
little budget as it is, is going to invest the money for a complete DRM
transisition. If anything, perhaps DRM will be assigned their own sub-band
but I doubt even that.
Just an opinion.

Er, one application is what I believe Radio NZ International is
already exploiting with its DRM transmissions to small Pacific Island
rebroadcasters..
The Major Broadcaster provides programming in DRM for high-quality
relay transmissions by a small organisation.
You might doubt and query: why not do that via satellite feed?
Ah, that might be outside the financial capabilities of the receiving
re-broadcast station.
You might not believe it, but (a recent report) highlighted lack of
simple office equipment such as chairs as being a problem for the
Solomon Islands Broadcasting Corporation... the SLBC also I recall has
had difficulty paying its electricity bill.
RHF
Nobody,
If that works for Radio New Zealand to the Islands
then it can work for Caribbean Island and many
Countries in African DRM as a lower cost Radio
distribution system then Satellite Based Systems.
what works WORKS ! ~ RHF

RHF and Nobody,
You are both correct. RNZI regard DRM as a redbroadcasting "option
(medium) to us isolated and fiscally challenged Islanders where high
speed digital access re. Satellite reception is expensive or just not
available.
This can be "really useful" in times of national emergencies such as
cyclones here. All we have is da magic radio (local LPFM) to tell us
what is going on "out there" and when we should dig a big hole and
hunker down. Hate that.!!!!

Chris/Samoa,
The other Weather 'problem' that I heard about
On-the-Radio; out there in RNZI Land {Ocean
Island Area} is High Tidal Surges when many
of the small Island 'Atolls' {Cays} can get
covered {immersed} with Ocean Water.

Good to get an early warning on that too.

RNZI's DRM service is presumably aimed at providing programming/news
content relay for quality re-broadcast by small national broadcasters,
not necessarily as emergency advisories.
I'll bet there are older New Zealand watchers to this news group who
can remember when the BBC/Beeb's shortwave newscasts were picked up at
the Makara site near Wellington to provide audio for the NZBS'
"National Stations" 6 p.m. NZT newscast followed by BBC Newsreel. That
off-air relay existed into the 1960's.
Satellite is available anywhere... the birds reflect... money for
reception might be a/the problem.
