I have no idea about radio, so I don’t know where stuff could be going wrong. I have tried two antennas already. It’s definitely not just weak satellites, it doesn’t even work with NOAA.
Using GQRX and your dongle/antenna - try to see if you can “hear” something of known frequency. If you have an amateur radio HT or FRS radio (or equivalent), those are the easiest. If not, you can also use automotive keyless entry FOBs (in the US, its pretty easy to look up the FCC id on the FOB to find out its operating frequency).
