As an amateur radio operator, The high bands get wiped first! 80, 160, not so much (no ionosphere? ground wave still works. Easy to throw up a long wire ... afterward). Hams (esp. ARES) will become VERY IMPORTANT for a LONG time when it happens. Field Day is a good way to prep for aftermath. (Gear can go into metal containers to escape parts damage until afterward.) Portable generators (best without a lot of electronics on them) will be needed to re-charge the batteries!
