That's what WSPR is for. There is a very well established worldwide network that can be found on nearly every band. Try it. You'll like it.
I never understood why PropNet suddenly went dark one day without notice. Perhaps bringing back PropNet would be the best overall option. I was an avid participant and was very disappointed when it went away. Maybe this time use a SIMPSK protocol instead of vanilla PSK31. Food for thought.
