Since my last update of FLDIGI that I run with a dedicated RTLSDR and SpyVerter my waterfall is blank but I can see the software decoding in the yellow portion of the screen above it. Wondering if I am missing some driver or DLL file or something. I have tried un-installing and re-installing the software via Control Panel all to no avail. I use VB Cable to route the audio from the RTLSDR to FLDIGI. Long-time user of VB Cable and it works with the RTLSDR nicely with WxToImg for weather satellite decoding so that makes me believe it is a FLDIGI issue.
