Digital Radio Mondeal - receiving radio & Knoppix via SW

[Robert Michel]

Salve!

You may know that a new standard for digital broadcast via LW,MW,SW
is out: Digital Radio Mondial. It is possible to broadcast 12-24kBit/s
and use this transmissions also for data-broadcast.
http://www.drm.org

Today there isn't a harware reciever to by, but analog radios can
be modyfied to recieve it and decode it with a soundcard and a PC
http://www.drmrx.org

There is also a software for Linux under GPL:
http://www.tu-darmstadt.de/fb/et/uet...f/DRM/DRM.html


First idea to add this softwarereciever to Knoppix,
Second idea to broadcast Knoppix worldwide via sw:
700MB/12KBit/s = 5d 8hours
Quite soon will be this a posibily to share the latest Knoppix and
broadcast it 2-4 time a year + everyday the latest security updates
once a day (f.e. between 3-4h GMT)

Any HamRadio freaks here?

Ham freak right here!
This is a really cool idea. You definatly got my attention.

I'm only a tech, so no HF for me yet... but I know people who would probably like to make this happen.

Salve Adamm / kd5qzg!

Great!

My idea based on some others:
- Some freaks had run a radio (I forgot if it was interntetradio or
teresticaly) where on computer reads the linux-kernel.
Comparable idea: www.spamradio.de
- One small town close to my city (Aachen,Germany,Europe) had
celebrated there 1000 yearsday with one week radio-programm,
broadcasting this localy and "worldwide" via sw to there
partner-town.
- DRM is a new technoglogy which support data-broadcast parallel or
alternative to the audio broadcast.

And now the best, close to Aachen has the German Telekom a sw-broadcast-center: Juelich (Jülich) http://www.telekom.de/dtag/ipl1/cda/...,10111,00.html

Some facts about Juelich:
12 PDM - transmitter (AM 400kW PEP, DAM 400kW PEP, SSB 350kW PEP)
42 Antennen (HR 4/4, HR 4/3, HR 4/2, Log. per. vertical, HR 1/2 turnable)
The Telekom sponsered this town-yearsday broadcast and also the broadcast licence for sw was not a problem.

At the first Broadcast it would cost allot of energie and the view
people which record the Knoppix-CD by SW would be got Knoppix faster
and cheaper by snailmail. But to data-broadcast a whole CD-ROM would
create a news-echo: PR for DRM, for Knoppix and GNU/Linux.
So primary I want make it for __BIG PR__
The first OS free from air *g*

When talking about SW most people think that the quality of singnal
change every moment, but would it be possible to receive on whole CD-ROM over 5-6 days without errors?

>I'm only a tech, so no HF for me yet... but I know people who would >probably like to make this happen.

Ask your friends if they believe data-broadcasting of a whole Live-Linux more than once (just for fun) would make sence.
Utopie: GNU-Radio or Debian-Radio once a week 1 hour radioshow about
the latest about GNU/Linux, some teaching and security alerts and
security updates with Data-broadcast on the same frequency -
receivable with cheap DRM-radios, worldwide without internet.

Probably it will be unpayable and sponsors will support it only
once - but just once it would be a great fun.

Alternativ to DRM would be satellites. Mornig hours are unpopulare
times and I think it is possibel to stream every sunday morning at
9:00h Knoppix via DVB. But this wouldn't be worldwide and not not
for developing countries. Also I would expect that worldwide there
will be more people with DRM-reciever than people with a DVB-PCI-card.

Both broadcast ideas can be used with a commercial addone:
Knoppix free for everybody, encrypted configure files and special software for fee paying coustumers (a way to financiate the free service)
...
Replys and participants wellcome!

Salve,
Is there a way of mixture of a live-linux Knoppix and a distribution
Debian? When GNU/Linux is data-broadcasted a live Linux should be
more modulare than KNOPPIX.
A mobile-phone, a satellit-receiver don't need a 700MB iso.
The chance to get new packages at anyplace of the world would
be very interesting for embedded PC, wetherstations, traffic-PCs...
The big updates via sw/drm for free and the configuration via GPRS/modem or sw/drm, too.
I think Live-Linux on CD-ROM like Knoppix is just the beginning
of new distributing ways of software

Hey there

I am trying to install drm on my HDD installed Knoppix (Debian woody). I installed fftw, faad, and Trolltech Qt with the apt-get instaruction.
So far, so good.
Now, when I try to run ./configure in the drm directory I always get the following error:
/*****
blah.. blah...
checking for fftw.h... yes
checking drfftw.h usability... yes
checking drfftw.h presence... yes
checking for drfftw.h... yes
checking rfftw.h usability... yes
checking rfftw.h presence... yes
checking for rfftw.h... yes
checking for main in -lqt-mt... yes
./configure: line 5307: ac_cv_lib_qt-mt=ac_cv_lib_qt-mt_main: command not found
checking for moc... no
configure: error: "No moc found in /bin"
*****/

I already tried to do a:
./configure --with-qt-includes=/usr/include/qt3 --with-qt-libs=/usr/lib/qt3

but same same...

Any Ideas? or am I doing it completely wrong?
