Thanks to all who responded. I see I've been misusing "ground wave" for
a long time, in place of "surface wave". And my apology to those I've
questioned about "ground wave" propagation at VHF/UHF. According to
correct usage, it does indeed exist -- just not with a surface wave
component.

Likewise, my apologies to anyone whom I've misled.

But I apologise with fingers crossed behind my back!

The IEEE Dictionary mavens have produced a very HF-centric definition of
"ground wave", by defining it to include all modes of propagation except
"sky wave"; where "sky" is exclusively defined as "ionospheric".

This definition completely ignores all the non-ionospheric VHF/UHF
propagation modes that don't involve the ground at all.

Since a misleading definition is worse than no definition at all, the
best policy for the term "ground wave" is to label it "Broken - Do Not
Use".
