Good question I honestly dont know but I'm asuming that if a big EMP toasts everything you can watch out for two things ( I'm guessing) First if we have a huge long EMP event then theres a high probability we will have northern lights shining brightly as far south as the south coast for days, and when they finally fade away the event should !!! be over. OR repair / reconnect / assemble a radio reciever and if its full of nothing but powerful interference then chances are the ionisphere is still being ionised etc.
