Anybody seen an issue where the SDR seems to go into oscillations and Unitrunker stops working? I've tried many combinations of settings to try and avoid it, but it continues to happen. See the attached screenshot of what i'm seeing when this occurs. I'm using the RTL SDR from Noo Electronics.

Thanks!

Could be - I did turn off the tuner AGC and manually increased the gain to the maximum level I could until I saw the noise floor begin to rise. With the tuner AGC turned on, it looks like it's getting turned up all of the way and the noise floor comes up about 10 dB. I was having the same problem with the tuner AGC turned on as well.

I have seen this many times while running the TCP selection. I see it with all AGC combinations. I have used remote desktop to view the rtl_tcp window on the server PC and see no errors there. Stop and restart via SDR# a few times and it settles down for quite a long time. I have been leaning towards a networking data interruption that initially sets off the oscillation. Are you running TCP on your local machine only or to a network PC like me?

I'm running TCP locally.

I have seen this running TCP and with the older version of SDR# that's out there in the setup instructions for USB.
