indeed 20 vs 12 MHz…
I did try that combo install but no joy bramjacobse
i started with stretch first no luck gonna wait now i cannot do stress hehe
john
For the Pi4 you have to use Buster.
sudo apt update
sudo apt install rpi-update
sudo apt dist-upgrade
sudo rpi-update
Say yes to the warning the last command has to offer.
It will give you the newest kernel.
Then rtl-sdr as well as airspy mini should work fine.
Pi4 stretch…?
Just to clarify rtl-sdr and airspy
but not dump1090-fa
regards john
dump1090-fa uses the rtl-sdr library to talk to the dongle.
rtl-sdr had a problem working and accordingly dump1090-fa didn’t work with dongles.
dump1090-fa itself without using a dongle was always working fine on the pi4. (net-only mode)
(don’t even know if the airspy ever didn’t work, but we know it’s working now)
Ok thanks
i see dump1090-fa is showing in top ssh list but not working dongle testing airspy after midnight tonight
Did you do the rpi-update?
Show:
sudo journalctl -eu dump1090-fa
uname -r

So if you have run airspy-conf, it’s not gonna run with a normal dongle.
Airspy-conf changes the configuration for it to work with the airspy.
There is even an uninstall for airspy-conf if you scroll all the way down:
GitHub - wiedehopf/airspy-conf: Configure airspy_adsb for use with readsb or piaware.
It should revert you to the normal dump1090-fa configuration you had before.
not run airspy conf yet its in loft running i will do swap later tonight see if all runs smooth
Well you have set it to net-only mode.
If you did that manually you shouldn’t be surprised it’s not working with an rtl-sdr dongle.
You are not really saying what exactly you are trying to do.
Maybe use some punctuation or just press Enter to separate the point you’re making
Ok im going to test out pi4 with airspy
airspy dongle currently running on pi3 in loft
would like the option of dump1090-fa after testing (uninstall airspy.conf)
i will test pi4 with airspy tonight midnight so i loose the least amount of data
and test -12 and -20 tomorrow and compare data through the day
basically looking to improve my data input
So you didn’t try to use a rtl-sdr dongle?
I’m still a little confused by the net-only mode you had set.
(I normally call only the rtl-sdr dongles dongle. And just call the airspy an airspy, even if it’s technically also a dongle )
If you are using an airspy, net-only mode is correct for dump1090-fa.
But you also have to have airspy_adsb running to feed data into dump1090-fa, otherwise it’s not useful.
dump1090-fa can’t use the airspy by itself.
airspy-conf takes care of running airspy_adsb as well.
i followed ins above inc airspy conf
i couldnt get serveral dongles to work
i see dump1090-fa in ssh list also airspy-adsb running
but no dongles run
i do have map up no error message or aircraft
airspy-adsb not currently running
The airpsy isn’t running?
Or are you trying to use rtl-sdr dongles?
They don’t work with the same settings.
Once you change dump1090-fa to net-only mode, rtl-sdr dongles are not gonna work.
If airspy_adsb should be running but isn’t, you can check that log as well:
sudo journalctl -eu airspy_adsb
Jul 16 21:12:42 raspberrypi airspy_adsb[401]: airspy_open() failed: AIRSPY_ERROR_NOT_FOUND (-5)
Correct ive not started airspy-adsb yet
commands correct ?
airspy_adsb
/etc/default/airspy_adsb
sudo systemctl restart airspy_adsb dump1090-fa
sudo nano airspy_adsb
systemctl status airspy_adsb
I’d heavily advise you to use the automatic setup.
That command is written nowhere in the howto and doesn’t make any sense.
The log shows you’ve set up airspy_adsb as a service.
If that is the case, you don’t need to start it manually.
The service is complaining the Airspy is not plugged in.
pi@raspberrypi:/etc/default $ systemctl status airspy_adsb
