Hi im new to SDR and having issues setting up SDR#. I'm trying to receive from GOMX-1 on 437.25 MHz for a project. My set up is the dongle, a LNA and a self built helical antenna for that frequency's measurements. I managed a couple of very noisy signals earlier this week but since haven't been able to re do it let alone improve on that. I've put a screenshot of the interface below - any support or advice would be most welcome!
I have previously received from NOAA using the dongle so the dongle is ok.
