This is looking good, now lets see if SatNOGS will also work.

@PE0SAT thank you so much.
I see few observations scheduled by you and one of them NOAA-19 captured signal too !!
This is amazing. Check this :

https://network.satnogs.org/observations/9142835/

The system is connected to a Diamond CP22e Ground Plane antenna. I will soon try to improve the antenna to a Turnstile. I thing that will improve the SNR to decode DATA.

Indeed, I saw some successful observations, great this finally worked.

Good luck with the next steps and tweaking the station.

@PE0SAT my ground station is now picking up signals. I am able to see NOAA-18 &19 signals on waterfall and can hear audio.

You are kindly requested to send me a list of Satellites which I should try to Prioritise and Auto Schedule to see the effectiveness of my homebrew Turnstile antenna setup.

Below a list from my VHF priority list, but keep in mind I am located in the Northern hemisphere (Europe) there are satellites that I can’t receive.
