Rick, very interesting post.  Only?  I don't think I have fifty countries 
confirmed in 46 years.  I listen in the extra areas, because that's where 
most of the dx is.
Let's see.  3775 to 3810, 7125 to 7200, 14150to 14-200, 18-120 to 18-145, 
really anywhere on 17 will do.
15 12 and 10, wait till they open.  You east coasters have it a lot easier.
