What we are lacking (aside from receivers) is some kind of cheap DRM exciter.
I did some experimenting using my SSTRAN AMT-3000 AM transmitter and DReaM. With some success, I began wondering about other options including the 13MHz ISM band. I see that a German company offers the DiRaGen 30. Judging from the fact that no price is listed, this is probably not affordable for our experimenting. Has anyone purchased or tried one of these? How about homebrew ideas?
