Hi guys,
first of all, congratulations for this interesting project!
I’m an Italian radio hamateur, (callsign IZ7BOJ) and I work in an Italian private Company which is involved in the deisng, assembly and test of microsatellites.
I’m using an RTL-SDR dongle and a home-made turnstile antenna (https://iz7boj.wordpress.com/2018/12/02/double-turnstile-construction-for-satellites-receiving-in-435mhz-band/ )for my first experiments in satellites decoding. I already decoded some 9k telemetries with Windows Software and I posted some data on satnogs DB by DK3WN telemetry forwarder.
Now I would like to contribute to satnogs netowrk, so I registered my station and started to configure my Raspberry pi3 with satnogs client.
I didn’t use the satnogs image just because my raspberry runs other applications and I prefer to keep the actual configuration.
I followed the satnogs instructions and I installed the client using Ansible.
I run satnogs-setup and I completed the basic configuration.
If I run “journalctl -u satnogs-client.service”, I got an error, which is reported below.
Can anyone help me?
Thanks in advance
