That I have to find out. One interesting observation though. Now that it 
is getting darker, the noise is going down. This is of course good news 
since this is 160m. I hadn't noticed this earlier because I was falsely 
assuming that it was broadband noise. But it is still 6 dB over the 
baseline outside the noise spectrum. The fans are still running normally 
there so it is not them.

The distance between my inv L and the chicken house is 1000' and I can 
move the antenna so that it would be 1300'. This might help some. Also 
adding some receiving antennas could eliminate a lot of it.

If the chicken house generates RF hash into the power company power 
lines, can I get the power company to get the guy to fix it? Are there 
any laws regarding this?
