I'm often thinking about the old VLF propagation graphs

original paper where it comes
from?) which make more and more sense to me!


There is also the wavevlf program by Piotr M#ynarski
SQ7MPJ (SK), which calculates the field strength based a spherical
waveguide model.

I have a modified version here:

This was used to generate the attached graph.
