I had some problems with my satnogs installation so I downloaded a new image two weeks ago, since then I have not been able to get any signal in the observations.
I have satnogs on a Raspberry Pi 3 Model B Plus Rev 1.3 with the latest version and an RTL-SDR plus LNA which is working perfectly (tested with rtl command line tools and sdr#).
One example of observation is this: SatNOGS Network - Observation 7428307
Can anyone think of anything I could be doing wrong?
The gain seems to be too high, try lower values.
Also can you generate and copy paste here the support report, check the second yellow box in this wiki page on how to.
I’ve tried multiple gains, even 0, that gain value worked perfectly ( SatNOGS Network - Observation 7253658 ) until now.
Here it goes my support report:

Try the following settings, they are working on my SatNOGS station that also has a LNA connected.
SATNOGS_SOAPY_RX_DEVICE="driver=rtlsdr"
SATNOGS_RX_SAMP_RATE="2.048e6"
SATNOGS_RF_GAIN="22.9"
SATNOGS_ANTENNA="RX"
SATNOGS_DEV_ARGS="biastee=true"
And just to be sure, do you have a RTL-SDR v3 with the Bias T enabled option active.
In the past there where v3 also models that didn’t have the option.
Good luck and please share you results.
Jan - PE0SAT
Settings set… will have to wait for the results.
As for the bias T, as I said, the rtlsdr is well tested with sdr# on windows and with the rtl suite on this Pi (in fact on the dead times its used to send data to flightradar24…)
Please share your configuration after the changes that where proposed.
If the setup works fine with SDR# then there is an error somewhere in the configuration.

Please share some log information sudo journalctl -f -u satnogs-client -n 512
And I would advice to remove all your RTLSDR settings an go back to basic settings, here an example.
satnogs_station_elev: '10'
satnogs_station_id: '1343'
satnogs_station_lat: '43.380'
satnogs_station_lon: '-3.853'
satnogs_soapy_rx_device: driver=rtlsdr
satnogs_dev_args: biastee=true
satnogs_rf_gain: '22.9'
satnogs_antenna: RX
satnogs_rx_samp_rate: 2.048e6
I will get that logs as soon as I get another observation running, for now there are lots of errors from an unestable connection, but nothing related with soapy or the sdr.
I will try to revert to that settings but I’ve already worked with that the firsts times after the new image.
Thanks!
