About 17dB signal/noise - unfortunately no music, just two guys chatting.

Usual WinRadio G303e with the Dream signal taken from the pseudo IF output, 20metre longwire running N-S about 6metres up. Always seem to get a good signal from Spain, but that's the first time I have had it good enough to decode.

Cool

DRM works quite well in most cases and especially with music. It's more prevalent in Europe than in the USA.

The only downside is that 99.9% of SW radios wouldn't be able to do much with it. So until the makers start putting in DRM decoding the standard will never catch on.

(The one DRM portable that was released a couple of years ago was discontinued. It was quite pricey too.)

I guess there are more receivers out there -- but these are not common brands -- or likely for sale in the USA:

It works only as well as propagation will allow...by no means is it always 'FM Quality' sound.

One of the biggest problems with DRM is that the sidebands tend to wipe out anything that happens to be underneath them pretty effectively. It's not so different from IBOC on the MW band in that regard - DXers absolutely hate hearing about a DRM frequency near something they're trying to hear. The language, sometimes, is not to be repeated for the faint of heart (hi)



We also have links in our wiki for several sites that have information on modifying radios. However, here in the US, it will probably always be just a curiosity item - as Nick says, it's much more prevalent in Europe (where the average person is much more aware of HF broadcasting than the same person here in North America...)
