Topband: AM BCB noise in Portland, OR

[Merv Schweigert]

Tree,  surely is not the problem I am having out here,  there are 
several stations
co-habiting a tower and the whole set up is junk, rusty and full of water, 
I contacted the engineer and he confirmed the problem,  but it has not been
repaired since Nov.  It is getting louder and louder,  over S9 here at my
sunset and well after,   it has gotten so bad it has spread to 80 meters 
now.
It sounds like cw,  hash type sound, like a bad connection somewhere,
(which it is)  there is now carriers every 10khz from 1700 to past 4 MHZ
and the go on and off with the bad connections.
Surely this has not propagated all the way to the mainland?
It is mixing from KNDI and two or three other stations out here on Oahu.
