Ok Doug,
Next dumb question. Are you doing anything special to reduce the wind noise? That much wind blaring over a standard fom pop filter makes an incredible amount of noise as we've heard in several tornado videos.
Are you using a "blimp", fur cover, or simply watching where you place the mic?
On external mic's I've found that I can reduce the wind noise considerably by using a fur cover. Of course the better quality ones are a little out of my reach for teh few extra db loss, but they do work. From what I can tell, the "blimps" are the best over all, but are generally used on a boom pole assembly and used more in filming movies rather than documentary or news gathering.
