978 UAT Traffic Types

My 978 receiver is showing two types of traffic. Predominant are ADS-B messages from light aircraft. There are a few listed as “other”


What other than the expected UAT signals are being received?
MLAT is zero as I have it disabled.

“other” is essentially anything without position information; could still be UAT (you just never heard a position)

I managed to have 1090 and 978 antennas onto the same RPi. I see 978 traffic in SkyView978. What I do not see is reports of the tracking on the FA My ADS-B page. When the antennas are using the same PiAware, will the 1090 and 978 traffic pop up in the same list “Flights with positions from this feeder in the last hour” ?

When I had 978 on a separate feeder with a separate ID, it showed up as expected.

Did you configure piaware to fetch data from dump978?

sudo piaware-config uat-receiver-type sdr

This should do the trick.
The statistics will be merged though.

how can I check that I did ?
I see the following:

root@odroid:~# piaware-config
receiver-host localhost # value set at /etc/piaware.conf:8
receiver-port 30005 # value set at /etc/piaware.conf:9
receiver-type rtlsdr # value set at /etc/piaware.conf:7
uat-sdr-gain 38.6 # value set at /etc/piaware.conf:10

Should have read better at @abcd567 post at link

piaware-status should show you if it’s using UAT data.

That won’t have any effect by the way.
Only works on the sd-card image.

When I restart piaware, I do see:
May 27 11:36:17 odroid sudo[14268]: pam_unix(sudo:session): session closed for user root

May 27 11:36:17 odroid piaware[14255]: ADS-B data program ‘dump1090-fa’ is listening on port 30005, so far so good

May 27 11:36:17 odroid piaware[14255]: Started faup1090 (pid 14270) to connect to dump1090-fa
May 27 11:36:17 odroid piaware[14255]: No faup978 found at , UAT support disabled
May 27 11:36:18 odroid piaware[14255]: piaware received a message from dump1090-fa!

Does that mean 978 is not running ?

I’m not sure what that means, sorry.
Looks like it’s not working.

Can you check the output of this command:

ls /usr/lib/piaware/helpers/

Indeed, it has no faup978

Tried a rebuilt of piaware as in: https://discussions.flightaware.com/t/dump978-add-on-installation-procedures/49377/17. No luck. Still no faup978…

Can’t you just install it from the repository?
Maybe there is a problem with the build you are not aware of.

it will be 32-bit version. That is fine, of course. As long as it does not interfere with the 64-bit build.

I’m not sure why the build wouldn’t work.

Are you still having trouble with this? Or have you given up with 978 UAT?

The reason I ask is because I just setup a PiAware (RPi) with both 1090 and 978 receivers successfully and can assist you if you still would like to pursue this.

My PiAware instance currently has 1090, 978 and MLAT enabled but we can disabled MLAT for your config if you don’t want to use that. I really just need to know what your Piaware-config.txt file looks like. Which you can access by using the following command.

Sudo nano /etc/piaware-config.txt

Assuming you are using a SD install. If not we can still do this it just might be a bit different. Just let me know if your interested!

This thread was about compiling piaware on Odroid.

piaware was not building faup978 which is necessary to feed.
I’m pretty sure that particular bug has been fixed and it was running fine on the Odroid.
But using an Airspy at 20 MHz in parallel did not work, so now the 978 stuff is on a separate pi anyway.
