Here is a possible "Market Indicator" about the Future and Fate
of both DRM on Shortwave and IBOC on AM and FM Broadcast Radio.

The proposed Mini-CCRadio that is scheduled for release this fall.
So do you see DRM or IBOC listed as a feature or an option ? - NO !

Here is one I know about. Both links are actually for the same radio by
two of the companies that are working together on it.

I wrote years ago that DRM portables would have a power problem. You
have to run a lot of processing to get the audio. In order to get the
power down to reasonable levels will require CMOS custom IC's that take
big bucks to develop. That is not going to happen unless the entire
coding and all algorithms become public property.

One year is in etternaty in electronics. :-)


Here are some press releases concerning DRM/DAB of the IFA
(Internationale Funk Aufstellung) Berlin and IBC Amsterdam (both where
held earlier this month):

If you run "drm dab receivers ifa ibc" throu your favourite
search-engine, you'll come up with more then sufficiant links.



These things are geared up for the European market: FM/RDS, AM (no SSB),
DAB, mp3 and wma-playback, SD/MMC interface, ...
Also note that the sangean radio builds on the design of their DAB-range
not on their range of SW-receivers.

So I guess these models will only have either MW and LW, and a limited
number of SW-bands (probably only the "local" bands), but it looks
logical they will work on this design in other variations, like
FM/AM/IBOC-FM/IBOC-AM for the US, or AM/FM/SSB/DRM for shortwave-receivers.


The receivers are expected by the end of the year, so we will know more
about features and prices.


Also note that the power-consumtion issue (as on the mayah) has been
solved as they have been working on DAB/DMB modules for inside
mobile-phones (DAB/DMB uses more power then DRM).

More information about the chipset can be found he

Finally notice that these radio's are market under the "DR" logo, which
combines DAB and DRM. So, this is not a "DRM" radio, but a "DR" radio!

The links I provided point to the only SW DRM concept radio that I know
of other than rack mount units.

The rest need a computer to process the audio.

The one SW concept radio I pointed to can not run on batteries.

The statements that I have seen before about DRM being an open standard
are as far as I see false because the software is not in the public
domain.

For this among other reasons the name "Deception Radio Mondiale" sticks.

Now you have heard the rest of the story... for now at least.
