[QCWA] Solar Cycle

However, as all of us old hams know, this happens every eleven years,
but as far as the general population is concerned it makes intense
headline news.  Probably more exciting that the end of the Mian
calendar hoopla.

There is probably a greater probability that a rogue nation will
detonate an EMP device in the atmosphere, causing just about as much
devastation, except that it will be in a more isolated area.

Read the novel "One Second After" and you will see what an EMP event
is and what will likely happen after the event.
