Yes, without co-ordination there may be interefernce problems during the
transmition period, but the sooner the world goes DRM the better
international radio broadcastings prospects IMHO.


Satellite radio does every thing DRM promises.

.... if you're in the US, which doesn't include 95% of the world.

The rest of the world has their own satellite radio service(s). The name
escapes me at the moment, but there is one service that covers most of the
(non-US) world in several regions.

I reiterate however, that people in third world and oppressive countries
will not have access/not be able to afford the receivers for either this or
DRM.

Worldspace, quite a proportion of its output now seems to be encrypted and aimed
at Western travellers.

will not have access/not be able to afford the receivers for either this or

Of course that reasoning also renders Worldspace redundant.

I think there's direct broadcast satellites serving areas outside the US.
The cost of satellite receivers is a real concern, but it's also a concern
for DRM. Anyway, the international broadcasters could get together and put
up a few direct broadcast satellites, if they really wanted to make the
investment.

DRM doesn't really get around shortwave's reliability problems. The
shortwave utility bands used to be filled with digital signals 25 years ago.
These signals were highly reliable. If there was any propagation at all,
they would get the message through. Despite having high power shortwave
transmitters, selective and sensitive receivers, highly directional
antennas, sometimes the message didn't get through. There's now only maybe
10% the utility traffic there once was. The balance, plus the whatever
expansion there was, went to satellites.

The utility stations wanted 100% reliable communication. They ditched SW.
