Right, but as I said in the other reply, while the "F-layer" promotes
"skip" on both MW and SW, the "D-layer"--which only affects MW, not
SW--is a wet blanket, absorbing F-layer skip, and is *also* more active
during high sunspot activity (actually it is the result of geomagnetic
storming that sunspot activity triggers).
