For the last week or so I can not get many stations. It is not like I have a bad antenna I have 450 feet worth of antenna. I should be pulling in the world, but I just have not been getting anything this week. I use to get almost every thing From Radio Korea to Radio Sweden; I have changed nothing, so I just want to figure out what the heck has gone wrong. I have heard talk about the Ionosphere acting up, I wonder if there is much truth to that talk, and if so if that is what I am getting hit with.
