Yup. SNOtel uses meteor bounce. They've talked about trying to switch to satellite or cellular, but it just doesn't make sense for their use case

BNSF railroad also has an extensive meteor scatter radio system across north america that is similar to SNOtel.

That sounds like stuff of science fiction, can't believe it works. The best part is that it works long distance without having to have satellites in the sky... and is probably un-jammable?

Thanks for sharing this, so cool to learn about it!

Had not heard of this, that's impressive.
