I finally got Station 1316 rebuilt after cables were damaged by the rotator, and I’m trying to get it on the network again. Here’s what’s happening. Observations start and run fine, but at the end this happens:

I did see the .ogg file in /tmp/.satnogs/data, and but it didn’t seem to have any audio when I looked in audacity (it does look like it has a good header and stuff in xxd). I can upload this OGG somewhere if anyone wants to look at it.
I am running the satnogs-client in a VM on an x86 server (worked fine on an old satnogs-client installation, maybe something changed). I already had issues with upgrading from Debian Stretch to Buster, so I made a new VM and installed Satnogs via Ansible from scratch for a clean slate. Also, due to a hardware issue, I replaced our old USRP2 with a brand new USRP N210 with a new daughterboard, and I am confident this one does not have any issues.
Let me know if I can provide any additional information. Thanks.
Here’s a little more log output - the only anomalous thing I see is the AGC warning, but I don’t think that is related. However I can’t figure out how to turn it off either.>

Finally, I have noticed that during the pass, I can see network activity the entire time that is indicative of IQ samples streaming to GNURadio. However /tmp/iq.dat never grows beyond 0 bytes.
This afternoon, after updating my satnogs, I have no waterfall at any observation…

Seems that only works with a sample rate of 1.024e6…I’d like to try with 0.250e6 because with Cubic SDR works better with that sample rate.
With 1.024e6 waterfall is working but audio seems interrupted, that why I¡d like to try with other sample rates values
