Re. my USB comment. Is the soundcard working OK for other apps, like playing music files,? if so my question re. USB driver is probably not relevant. Is the rx frequency control (which uses the USB) working when you use the "SoftRock Configuration Tool"? The latter should show that the Si570 is connected and succeed in changing the frequency. If that is OK and the display is still not showing the band signals, then I would guess that the USB for the rx is OK (but that USB control dll file has to be in the HDSDR directory as well as in the CFSGR exe directory I think). The cabling from the rx to the soundcard line input (not line output in spite of what it says on the rx) might be worth looking into also. My setup is quite sensitive to the sound cable quality and length. I am new to the SoftRock world myself, so hopefully one of the experts will have the solution for you.
