The report contains detailed information on two major experimental programs, propagation over a polar ice cap and propagation across a day night transition, plus two lesser programs, a set of test data for comparison with an experimental version of the VLF propagation prediction code being developed at NEL - San Diego, and a brief investigation into the propagation behavior of the optimum mode corresponding to a vertical magnetic field with an extremely low range-attenuation rate.
