Topband: AM interference on 1840

[GEORGE WALLNER]

There are two messages in this topic: One is the interference from this 
particular BC station. Not a crisis, not yet. Two is a warning: Newly 
installed solid-state AM broadcast amplifiers in poorly regulated regions, 
over time, will have the potential to fill the entire 160 meter band with 
harmonics. The second part is not trivial and should be a heads-up. The 
earlier we find ways to deal with it, the better.
