This situation produces unexpectedly high MUF's (due to the very low
angle of incidence) and the F2F2 mode (double-hop without any intermed-
iate ground reflection and absorption losses). This path may be somewhat
critical as either too much or too little ionization either end will cause
an overshoot or undershoot of the other bulge.
Future parts of this "mini series" on VHF F2 effects will consider
the seasonal effects, magnetic storm influences, WWV forecasting, and
transequatorial scatter (TE). It is hoped that this has (and will) been
of use to those DXers only experienced in the Es and trop propagation
forms. As always, direct comments are welcomed.
