DRM radio

[Norm X]

I'm kind of interested in listening to state sponsored propaganda from
Europe and Asia. eBay prices for DRM radio look good. Does anybody here know
if it can be received in North America? Is there a PC board or USB adapter
that will do the trick?

The most convincing solution I found was:

http://sourceforge.net/apps/mediawiki/drm/index.php?title=Main_Page

For short-wave reception you need good 15m length antenna wire up a tree.
The handheld models don't work and have short battery life because of the
processing power required.

It's all about the antennas!

There are a number of useful videos on Youtube. For skywave reception a long
horizontal wire at tree level is best. A skywave involves a potential
difference between the atmosphere and earth so for best reception the long
antenna wire should be connected to coaxial cable with the shield connected
to earth. A perfectionist would use a balun and test with SWR meter. The
coax into the home also solves the problem that there is a great amount of
broadband RF noise emitted from things like fluorescent lights. The antenna
can be set up for maybe $10 but is does involve physical work. Software
defined radio like DRM gives CD quality and other benefits but if the SNR
falls too low even ECC will not recover the signal. Hence, I don't think
many people in North America are listening to European DRM.
