Default Is There Any Future For Shortwave Radio : With or Without DRM . . .

BURR,

The American AM & FM Broadcasters to some degree
feel they got burned by IBOC "HD" Radio Scheme.

The NASB is most likely looking at FCC and International
Pressure to start some Shortwave Broadcasting using DRM.

The NASB would like to know / what to know if the present
Shortwave Radio Listeners will follow and BUY New Shortwave
Radios that feature DRM ???

Me thinks that the average Age {Demographics} of Shortwave
Radio Listeners (SWLs) and those who are willing to spend
the Extra $150 for a new DRM Shortwave Radio are small
and getting smaller.

NOTE - Above the $150 Cost Range : Gets people to think
that a PC/Internet and Satellite is the better deal for the
Added Price; and gives better quality Audio plus Video too.

*IF* The Shortwave Radio Broadcasters of the World with
Government Backing could make and market a 'portable'
AM & FM Shortwave Radio like the Redsun RP2100 Radio
{C Crane SW} for under US$100 then there would be a
World-Wide Market for DRM Shortwave Broadcasters.

http://www.radiointel.com/review-redsunrp2100.htm

NOTE - Not a 12 kHz IF-Output Jack to hook-up to a PC
to Decode the DRM Signal -but- Real Built-In DRM in the
Radio itself. {no extra techie required}
-aka- Just Turn It 'On' and Listen
-wrt- Free Over-the-Air Radio*
* AM/FM/SW Radio + AC/DC Power + You-the-Listener

IMHO - Without a low-cost 'Affordable' DRM 'portable' AM
& FM Shortwave Radio designed for the World Market
{Available in every Country} there is NO Future
for DRM Broadcasting.

IBOC has the 'possibility' of HD-Radio "Installs" in many/
most New American Cars & Trucks to act as a Decade
Long passive transitioning modus : While DRM Shortwave
has No Means To It's End of Gaining General SWL Acceptance
and becoming the Average Shortwave Radio Listener's
'normal' way of Receiving Shortwave Radio Broadcasts.

PLUS Real Time World-Wide "Audio Content" that was
Exclusive to Shortwave Radio Broadcasting is now available
via several other forms of Audio and Video Media Transmission :
Satellite, Internet, Cellphone, etc ::: The Combination of Audio
and Video Media is simply more compelling then Audio Along
and Shortwave Radio Broadcasting is simply Audio Along.

It's the old story of the Railroads seeing themselves as railroads
and not Transportation Companies : Therefore NOT Using their
Economic Might to Get Into the Airline Business and Dominate
It early-on.

Many/Most Government/National Shortwave Radio Broadcasters
are NOW! Government/National Media Distributors -via- Satellite
Radio & TV; Internet Radio & TV; Cellphone PodCast; and oh
yes... some still do some Shortwave Radio Broadcasting too...

- I'd be willing to spend more money for a radio

Steve,

*IF* Like XM/Sirius Satellite Radio DRM could come
up with a simple uniform Plug-and-Play Box.

Like the XM Receiver/Antenna for the Eton E1-XM
Radio that would be a good 'bridge' between an
old non-DRM Radio and an Integrated DRM Radio.

The Shortwave Radio Broadcasters have to see some
ROI coming out of DRM; or they simply will move on

as their main Technical Means to Their End of Reaching
and Communicating with People All Around the World.

stations which provide streams ... NPR is the FM that I grab, on the net
.... point being, it is getting hard to not realize the fact we could do
without standalone radios ... with probably keep my USB software driven

DRM is just too silly to be bothered with. I don't think the wife and I

In that case I think they'd better forget about DRM. A smarter move
would be for broadcasters to move to single sideband operations. This
might not give them a larger audience, but it would sure allow them to
cut a lot of their expenses. All they'd really need is a stock ham
transceiver and a dipole. And I'll bet that at this moment there are
more small receivers capable of receiving SSB than DRM.

Even better would be double-sideband-reduce-carrier. It's easy to generate
with DSP and sort of in between SSB and AM. It's basicly USB and LSB at the
same time. Twice the cost of SSB in terms of power and bandwidth, but far less
in power than AM.

It has the advantage that a standard AM receiver has no trouble with it.

The Sony IFC-2010 (ICF-2001D) was born because Sony had a warehouse of AM
stereo decoder chips and no market for them.

At this point it would not cost a lot of money to make a dedicated DSP
chip that would decode AM, DSBRC, and SSB at an IF of 445kHz. Possibly
a brodcasters or radio manufacturer's association could get together and
bankroll it.

Indeed. Yes, I think an approach like this would make much more sense
for broadcasters given the business realities they currently face.

Yes sometimes the better "Idea" is the simpler 'idea' :

DRM requires a more complex Radio Transmission process.

Plus DRM requires a more complex Radio Receiver
adding a higher initial cost to the Radio Listener to
Buy the Radio to hear the Broadcast.

The Better "Idea" Gets Better !

DSB and Suppress {Reduced} Carrier has many of the
Advantages of SSB : Plus the better Sound Quality of
AM Radio.

- It's easy to generate with DSP and sort of in between
- SSB and AM.

YES - PLus any current AM Radio or SSB Receiver can
also receive DSB Transmissions. Backward compatible
with AM Radios and SSB Receivers.

- It's basicly USB and LSB at the same time.

YES - WWV/WWVH uses DSB while CHU uses USB.

- Twice the cost of SSB in terms of power and bandwidth,
- but far less in power than AM.

Redirect the Wasted AM Power to the Side-Bands

100KW AM = 50KW Carrier + 25KW LSB + 25 KW USB

100KW DSB = + 40 KW LSB + 40 KW USB & 20 KW SRAMC*
* Suppressed {Reduced} AM Carrier
-result- Same Total Power Level :
But More Power To The Content :
And A More Powerful Audio Stream.

- It has the advantage that a standard AM receiver
- has no trouble with it.

Yes Yes Yes - Backward compatible with AM Radios
and SSB Receivers.

Plus DSB has the better Sound Quality of AM Radio
and even the potential of Stereo or at least 'enhanced'
Mono.

- The Sony IFC-2010 (ICF-2001D) was born because
- Sony had a warehouse of AM stereo decoder chips
- and no market for them.

Yes that brings up the 2nd Point the AM Stereo Decoder
Chip Designs can be used to Detect and Receive DSB
and Use it as with an AM-SYNC Function; and even the
potential of Stereo or at least 'enhanced' Mono.

- At this point it would not cost a lot of money to make
- a dedicated DSP chip that would decode AM, DSBRC,
- and SSB at an IF of 445kHz.

As you have point-out SONY already has the design.
Plus Drake/Eton/Grundig also has the Designs; along
with several others...

It's just a matter of starting-up production and producing
a Million Chips a Month for a Year and Warehousing them
and then Distributing them as they sell to meet the need...

- a brodcasters or radio manufacturer's association could
- get together and bankroll it.

Better a Consortium of Governments could simply
Mandate DSB Braodcasting and Create-The-Need :
Then the Capital would Flow to It Naturally.

OBTW-IMHO : Versus IBOC for the AM/MW Radio Band
DSB is the Better Idea !

-cause- Once you have the DSB Chips in the 'portable'
AM/FM Shortwave Radios* : Using DSB in AM/MW
Radio function is a No Cost No Brainer !
* +90% of the Sales of all Shortwave Radio World Wide.

- - might not give them a larger audience, but it would sure allow
them to
- - cut a lot of their expenses. All they'd really need is a stock ham
- - transceiver and a dipole. And I'll bet that at this moment there
are
- - more small receivers capable of receiving SSB than DRM.

- Even better would be double-sideband-reduce-carrier.http://groups.google.com/group/rec.r...60d4ae9e1f1be4

The Better "Idea" Gets Better !

DSB and Suppress {Reduced} Carrier has many of the
Advantages of SSB : Plus the better Sound Quality of
AM Radio.

- It's easy to generate with DSP and sort of in between
- SSB and AM.

YES - PLus any current AM Radio or SSB Receiver can
also receive DSB Transmissions. Backward compatible
with AM Radios and SSB Receivers.

- It's basicly USB and LSB at the same time.


- YES - WWV/WWVH uses DSB while CHU uses USB.

WWV/WWVH uses DSB* on 2.5 MHz; 5&10&15&20 MHz

* Double Side-Band Amplitude Modulation [DSB-AM]
Most times the AM-SYNC function on my GS800-M
Radio enhances the WWV Signal's Audio and does
improve it's Listenability.

CHU uses USB* on 3330 kHz; 7850 kHz & 14670 kHz
http://en.wikipedia.org/wiki/CHU_%28radio_station%29
* Upper-Side-Band [USB] The CHU Time Signal is AM;
with the LSB suppressed (Transmission Type H3E)

WWV "The Tick !" : All 'The Time' : All The Time !
? A Clear Channel Station ?
