Can't seem to get the software working with the RTL-SDR Blog v4. Dongle works fine in all other SDR apps, but SkyRoof can't seem to initialize it, the SDR status stays red.

Interestingly, the device appears to be incorrectly listed in the SDR Devices list, it shows as Generic "RTL2832U OEM" rather than "RTLSDRBlog Blog v4", which is reported by SDR++, GQRX, etc.

GQRX and SkyRoof both use the same engine, SoapySDR, to control the SDR radios. If your SDR works in one program but not in the
other, this is most likely due to different dll files that implement the SDR support. In your case the dll's are rtlsdr.dll and
rtlsdrSupport.dll. Please try to get these dll's from one project and use them in the other, and see if this solves the problem.

GQRX does not include rtlsdr.dll, so instead I downloaded the original driver release for the RTL-SDR v4 and used the rtlsdr.dll file from that package.That seemed to do the trick and works perfectly. Thankyou.
