GQRX blowout

Post by novice144 » Mon Jul 06, 2020 10:42 pm

Never-ending saga.... I was tooling around with my new upverter, which I had attached to my RTL-SDR dongle, then I removed the upverter, reattached the dipole antenna, and tried to activate my regular SDR software. All of my software packages were disabled. After several reboots, GNU Radio and NRSC5 are running again, but it seems like the RF Gain for NRSC5 is not as strong as it had been. However, the main problem is that GQRX is showing me the waterfall, but the frequency view is blank and there is no audio for GQRX. I am getting audio on GNU Radio for live signals and for recordings I had made, and there is audio for NRSC5, but GQRX is dead except for the waterfall. No frequency signals and no audio, just the waterfall. Can someone explain what happened and how to fix it? Thanks. Here is the Terminal readout for GQRX:

Just an update... Everything is working again. I don't know why trying to use the upverter temporarily disabled all of my SDR software, but everything is running correctly now.
