Of course, it would help if you told them what you were talking about!
DRM stands for Digital Radio Mondiale. It is a mode that is somewhat similar to IBOC in intent - it provides more fidelity to a HF signal, giving it an almost FM type sound. It's being touted as the way to bring SW to the masses - we all know that under normal conditions, a HF signal, even if it's very strong, is limited in that department.
As such, a DRM signal tuned on a regular receiver is nothing but noise. Therein lies the problem for folks that tune for weaker stations that are sometimes nearby - the sidebands tend to completely clobber them. In addition, with the exception of the Winradio series, there are no mass-produced radios currently in North America that can receive this mode. RadioIntel has had news in the past of portables set up for this, but they are generally coming out of China, or one of the Euro markets. There's no market for DRM here in the States yet, and without some education and heavy marketing, it's not gonna happen.
To receive a DRM signal, you need to tap the detector output (sound familiar? Yes, it's not unlike tapping a discriminator off a scanner to run programs like UniTrunker). There are software packages available to copy this - one called DReaM has been floating around for some time, another used by the WinRadio folks (I believe there is more than 1 version...).
Some WinRadio receivers are already set up for this, and can run their software without modifications. Anyway, not all radios seem to have the ability to feed a signal correctly, even with a detector tap.

Look at the center of the page for the DRM resources. And pray it doesn't come to a station near you.....
