RE: DIY NOAA 15, 18, and 19 Satellite Images with how to - Tuesday

Your welcome! A couple other sites to check out:
https://www.rtl-sdr.com/ Site dedicated to SDR
http://www.websdr.org/ Web based SDRs from around the world with various frequencies available

I used Websdr to follow the ISS around the world to catch all the 12 image signals as well as my SDR and antenna.

Some SSTV sites:
https://www.ariss.org/

https://amsat-uk.org/beginners/iss-sstv/
http://users.belgacom.net/hamradio/rxsstv.htm SSTV decoding software
https://hamsoft.ca/pages/mmsstv.php Another SSTV decoding software

I have found that a bandwidth of 50MHz is about right to fully catch the NOAA signals without having to follow the doppler shift.

There are other brands of SDR out there and some that do much more than mine.
