A consideration of Earth's magnetic vector will help us predict the
affect on the radio bands.

In between the period of vector direction up and vector direction down
we will have a short period of vector magnitude zero; during which
Earth's cosmic radiation shield will vanish.

Only those short wave personalities whose listeners happen to be
wearing protective tinfoil hats will have an audience which survives
the conflagration.

So. for example, the Brother Stairs and the Rush Limbaugh programs
should be among the few which survive the pole flip.
