The BIG problem is that probably 99.999% of CBers and a significant % of amateurs do not use the term "ground wave" properly. True ground wave does NOT exist at 30 MHz and dies off rapidly above 3 MHz, yes three megahertz. It's another one of those things I got tired of repeating as it is like yelling in a vacuum.


They think that if it is not sky wave propagation, then it is ground wave propagation.
