FT-8 seems to be a very popular low power mode for HF operations. I plan on trying it soon.
You can download the software for a mac at https://www.machamradio.com/blog/category/wsjt-x/ or a window platform at https://physics.princeton.edu/pulsar/k1jt/wsjtx.html

There are plenty of good youtube videos on FT-8.
Have a try and get radio active.
