G3B11
Answer: AWhat happens to HF propagation when the LUF exceeds the MUF?
APropagation via ordinary skywave communications is not possible over that path
BHF communications over the path are enhanced
CDouble-hop propagation along the path is more common
DPropagation over the path on all HF frequencies is enhanced
