Hackrf, like the rest of SDR receivers, have not enough sensitivity to receive directly those NOAA APT maps with the stock rod antenna. To receive those signals , the best would be to use an omnidirectional QFH 137 Mhz antenna band ,or a proper 137 Mhz dipole + bandpass amplifier.
You can tune , inputting directly any of the 3 x above current NOAA Satellite frequencies ,and check at what exact time , the satellite will be visible in his orbital pass. (there are many programms and web links to check the pass to your local place ) .
You can tune , inputting directly any of the 3 x above current NOAA Satellite frequencies (NOAA 15: 137.62MHz. NOAA 18: 137.9125MHz. NOAA 19: 137.1MHz) ,and check at what exact time , the satellite will be visible in his orbital pass. (there are many programms and web links to check the exact local time pass to your ground station place ) .
Here you have, some predict and tracking web links examples :
To check [NOAA 15](https://www.n2yo.com/satellite/?s=25338), real time tracking position or next 10 day prediction passes to your location (based on your IP).
