Hello all,

i have the following configuration for the Airspy R2 with LNA via Bias-Tee. Unfortunately, I do not get any signals. What have I done wrong?

Thanks for the help and 73

Hi @naval

It looks like that something crashes during your observations, to help you find out what it is, there are two steps:

  1. Generate and copy paste here the support report of your station
  2. Check and copy paste here the latest logs of satnogs-client

To find both the report and the logs, follow the instructions in the yellow boxes in this wiki page Troubleshooting - SatNOGS Wiki.

What gives?

SoapySDRUtil --probe=“airspy”

Thanks for the feedback geoscan: is that correct?
Basic configuration options
SATNOGS_SOAPY_RX_DEVICE *Define Soapy RX device SoapySDRUtil --probe=airspy, biastee=true

No :slight_smile:
It was right before in satnogs-setup settings.
I meant, what is the output when you run following command in RPI terminal?

SoapySDRUtil --probe=“airspy”

Looks good.
It’s just a guess, but maybe try:

“satnogs_other_settings”: “LNA=10,MIX=7,VGA=11”,

Have look at New Airspy R2/Mini driver development
