I had an interesting event last night... We had a power fail, and I had
my EMCOM equipment in place in short order, so I was able to bring up
the entire station. I got a chance to look at my base RFI levels, with
most of the houses for a few blocks radius around me without power.
My base RFI levels on 40 were around S4 to S5, (6BTV), during the power
Once the power came back, they increased only a single S unit, bringing
my RFI base level to S5 to S6.
Given that five years ago the base RFI level here were on teh order of
20 over S9 due to several grow operations close by, I have finally
gotten the chance to see just how effective five years of RFI hunting,
and knocking on doors has been!
I know how to get another S unit reduction, there is a grow op several
blocks from me causing about one S unit of increase across the board.
He looks to be moving, so I will leave well enough alone for a while.
Just thought I'd share the opportunity for a base line RFI check with
most of the really local sources gone. Having a K3 and using the band
scope is a dream for tagging RFI sources...
73s and thanks,
