blocksat-rx-gui not displaying signal after using other GNURadio software
634-5789 opened this issue · 1 comments
My enthusiasm was great but short lived. Everything worked great until I wanted to look/play around with the signal with gqrx. A SDR receiver powered by GNU Radio.
When restarting the blocksat-rx-gui again the signal couldn't be found anymore, just white noise. When starting gqrx again and pointing it to the frequency I give as a parameter to blocksat-rx-gui I still can see the signal.
blocksat-rx messages at startup are:

Did gqrx maybe change some GNU radio parameters that blocksat-rx-gui doesn't change back? Where can I start to troubleshoot?
Unplugging the SDR Stick for not only seconds but a minute or so magically solved the problem. Maybe some settings gqrx made where not reset due to too much of a short time being unplugged and having some power left.
