[RFI] Politics and RFI

[Roger (K8RI)]

I agree with Jim, but fortunately none is none.
Expertise?  I'd lay a lot more to luck as I'm located near a corner in a 
mid-scale rural subdivision with 10 homes within roughly 300 yards. At 
least the lots are large. It's woods on the W (back yard) and N of me. 
To the S of me on the E/W road there's about 5 houses E and W  and 3 
across the road N of me.
OTOH it's a relatively old subdivision so I expect a few sources to pop 
up.  Power failures? We get too many of those. I've put well over a 100 
hours on my generator in the last ten years.  I run everything in here 
except the amp off a 3 KVA true sin wave line conditioner. Killing the 
main breakers with everything disconnected from the line conditioner 
doesn't change the noise.

Generally at 3, or 4 AM, the S meter sets right down on the peg on 40 
meters. I just turned the rig on and was a surprise  to see it setting 
on the pin.  An intermittent hash came on which appeared to be from 
someone tuning up quite a way down the band, but that went away.  It 
sounded like operating on six meters for a while. There's usually a lot 
more noise in the day time.

Just had a nice QSO with WA1Y on 7.163 @ abt 10 over.   First daytime 
QSO in years.
After the QSO another station called but his signal just wasn't making it.
The band noise is now about S3, occasionally dropping to about 1.5
