Dump978 error help (short write, samples lost, exiting)

FlightAware ADS-B Flight Tracking
1

I’ve recently set up a nano three antenna on a raspberry pi and went through the instructions to successfully set up rtl-sdr. I also pulled the dump978 repo off of github.

I don’t get errors when I run rtl_test but when I run rtl_sdr -f 978000000 -s 2083334 -g 48 - | /home/pi/dump978/dump978 | /home/pi/dump978/uat2text which is supposed to output the messages in my terminal, it starts sampling and then abruptly stops before any messages show up.

output:

bash: /home/pi/dump978 Is a directory

What could I be doing wrong here?

Please use dump978-fa (GitHub - flightaware/dump978: FlightAware's 978MHz UAT demodulator), the older dump978 is obsolete and unsupported (I am the author of both)

There are prebuilt armhf debian/raspbian packages suitable for a Pi available from the FlightAware repository.

Thank you this is super helpful! I’ll get these installed!

So I set up the piaware install per the directions here PiAware - dump1090 ADS-B integration with FlightAware - FlightAware and then changed the settings so that it would be using the dump978 only with these commands

sudo piaware-config uat-receiver-type sdr
sudo piaware-config receiver-type none
sudo systemctl restart piaware

But for some reason when I try to use telnet to see the raw messages on port 30978 it fails to connect. Checking the ports in use on my pi gives me this output

(edit: not sure why that pasted incorrectly but it did identify that those ports were all in use by 355/dump1090-fa)

so something isn’t working and it’s still just running the dump1090. I can’t find any other/different instructions from what I did. Am I missing a step?

You’re not using the piaware image?
Then you need to do somet stuff:
https://github.com/wiedehopf/adsb-wiki/wiki/Installing-dump978-fa-and-feeding-adsbexchange-with-UAT-traffic

You have 2 SDRs?

6

I’m trying it now with the image to see if that works easier. But no, only one SDR antenna, but I only care about the 978 stuff.

Seems instead of installing dump978-fa, you have by mistake installed dump1090-fa

9

Seems instead of installing dump 978 -fa, you have by mistake installed dump 1090 -fa

I had installed both per the installation guide.

At any rate, the image version of piaware seems to work. I’m not getting any messages when I get port 30978. I just see this and it waits without receiving anything

!fecfix=1;program=dump978-fa;version=5.0;

I’m only a mile from a small-size airport so I thought I’d get messages no problem. It’s blizzarding out now, so I don’t expect air traffic, but I assumed I should at least be seeing the METAR messages, so it’s kinda weird.

10

To see uplink FIS-B messages you’d need approximate line of sight to one of the FAA’s 978MHz ground transmitters (they’re not necessarily at the airport)

note that skyaware / piaware et al do not decode/display uplink messages (but you should see the raw messages in the port 30978 output if they’re being received)

I am located at Toronto, which has 0 to 5 UAT equipped flights per day. Initially I also get this when check, but after some wait more data:
