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!
