Hello all, I'm new to ADSBX and have beginning setup with both 1090 and 978 (Westcoast of USA). Raspbery Pi 4 with the GlobalExchange op system. All was going well for a couple weeks until my 978 stopped reporting any data. I may have myself to blame because I was experimenting with the ADSBX image and ran updates and made other system changes. Is it possible I've accidentally updated the drivers for the 978? Or corrupted it or maybe it just overheated or just died? I've reloaded a fresh image and set up the system again from the beginning but the problem remains, no plane are being tracked by the 978 UAT system. I use to see a couple a day. All good with 1090. Any advice is welcome, Thanks.
If you open the command line, and do "rtl_test", do you see both dongles? Also, in the web UI, in the "info" category there is a section with dump978 logs. Anything useful there?
ok...thanks Dan.

The instructions seemed a little vague on how to assign the dongles.

That's not enough log to see what happens. Let's see the output for this command: sudo timeout 30 rtl_test -d 978 Also this log: sudo journalctl -u dump978-fa -e | tail -n40 The serials are fine, have you assigned what readsb / dump978-fa should use, there is a page for that on the image. "Assign SDRs to services"
Thanks wiedehopf and Dan, yes, I've assigned SDRs to services. I do have the option for stratuxv3 under 978 but have it set to 978. I was adjusting the gain a bit. I now have 978 plugged directly into the pi. I can test the USB ports on USB1/2. Both 1090 and 978 are plugged into USB 3. I'd assume that doesn't matter but welcome any guidance on that. Also, have any of you used the zerotier services? Is that like a ADSBX help desk?

zerotier support really shouldn't be necessary 978 seems to be working. Can you check the graphs for 978 activity? The most likely culprits are the power supply and the 978 stick slowly dying. Anything in regards to voltage drops in System Info?
I guess all is ok, just a lot less traffic lately on 978 it seems. Normally is see more helicopters, maybe from the local hospitals. But traffic is coming in. I think I'm good. Thanks wiedehopf and Dan. . Messages since boot: 1090mhz: 998,760 978mhz: 492 Tracks: 711
You increased gain yes? Don't do that, go back to 36 which is the default. If you have a proper antenna too much gain will cause you not to pick up close by UAT stuff.
yes, I set gain to 36 and all looks good. Thanks for the help. Messages since boot: 1090mhz: 17,302,541 978mhz: 47,503 Tracks: 11,747
