Hi Dirk, I don't have the Elektor kit, so cannot comment specifically for it. To receive DRM of course you need a DRM decoder program. It is economically almost impossible for a hobbyist to write a DRM decoder program, as when you want to distribute it, you have to pay a substantial amount of money to the German Fraunhofer Institute who holds all the patents for the DRM algorithms.
On Internet you are able to find the DreaM 1.9.3 program, either in source code format (perfectly legal) or already compiled (illegal if they haven't paid the license, which I don't know). Then you have to route the 12 kHz wide output of Winrad to that program using VAC (Virtual Audio Cable), or, if you have already two sound cards in your PC, by cabling the Line-Out of one to the Line-In of the other. Using VAC and the SDR-14, the SDR-IQ or the Perseus receivers, I have been able to receive high quality DRM signals. Keep in mind tha DRM is much affected by selective fading, in my experience. Where I live (Northern Italy) there is a local station (RAI 1, at 693 kHz) that has a constant and very strong signal. Tuning to it, DRM works beautifully. My favorite, from the point of the material transmitted and its audio quality, is the German station of Langenberg at 1593 kHz. Unfortunately during practically all the day it is affected by selective fading that cause dropouts in the recovered audio. It's a pity, they have excellent music programs. 73 Alberto I2PHD --------------------------------------- DF Ganzinga wrote: > Hi Alberto, can you elaborate on DRM-reception with the Elektor kit? > So far I only got a few seconds of serious DRM at a time with DRM1.61. > With your software I hear only a slight hiss. > Really, your software is much better than G8's.
