Michael…
The whole digital world is using FT8.
You can try PSK 31…BUT … You’ll spend a lot of time calling CQ and not working anybody.
You’ll want to use the WSJT – X Software.
You can Google where to find it.
Signal link probably has some installation and usage tips for FT8 on their website.
Also…Google ZL2IFB FT8 Guide. It’s a great resource…85 Pages!
