Hi Fred

what have you been using before for LF  ??
and what is the antenna,,, the annoying signal is probably
local and be glad you dont live near a hospital,,, mine is
loaded with switching power for there elevators and other 
noise sources

Now that I can listen on the LF Band without bleed through from 80m, I'm 
seeing  a very strange strong signal.  It appears suddenly, in the 
general range of 250 - 500 Kcs [have to use the most reverent term 
around the Holy Frequency :-)]
