Hi Alex,

Love the application concept! Unfortunately it's not recognizing the RTL-SDR V4 I have plugged in. Other programs (SDR++, etc have no issue.)

The red circle on the SDR is showing and I've attached the log file. I wasn't sure if I needed SDRPlay installed, but installed it anyway.

Thank you for your help!

Please see this posting. Is this something you can try?

I pulled the two .dll files from other application folders where it's working and replaced the default .dlls here: C:\Program Files\Afreet\SkyRoof\lib\SoapySDR\modules0.8

This did not work :-(

First up, SkyRoof is awesome ! Just wanted to get that out of the way.

Secondly, I too can't make it work with the RTL-SDR Blog v4, though my v3 dongle works fine. Delving a bit deeper into it, this seems to be an issue with SoapySDR which has recognized issues with getting the v4 to work. There's a discussion about it here on the SoapyRTLSDR Github but there doesn't yet seem to be a solution to it.

Awesome app and thanks much! I have exact same issue. V4 works with SDR# can tune in a local FM station but the waterfall is blue with no activity

This issue appears to now be resolved once I tried version 1.7 BETA. Thank you, Alex!
