[RFI] RFI Identification Help

[Mike Ryan]

Still sounds to me like there is street lamp that is trying to start, is 
defective, and fails to start over and over. Since the photo electric cell 
is preventing the start-up during the day, your noise is only heard at 
night....perhaps begins at dusk?   ...you might want to make note of that. 
In this area of Florida, some people have these installed over their 
driveways and many, many have them over their boat docks behind their 
houses.  These are privately owned and the power company can't fix them for 
that reason. At the request of an owner who wants a lamp but has no means to 
install it, the power company will install them and bills the owners monthly 
for the service. Any of these in FRONT of homes should be easy to spot, 
whether they be high up or just mounted over a garage door flooding light 
over the driveway, etc. It is the ones to the REAR of a house that can be a 
challenge to spot.  THat's my two cents.
Good luck.  - Mike

I pretty much determined it isn't coming from my house.  This morning I had
a little time before work, and the noise showed up again, so I turned off
all circuit breakers except for the one that the shack was on.  My daughters
bedroom is on the same breaker, but I turned off all of the power strips in
her room and that turned everything off.  Also turned off everything else in
the shack except for the power strip that the rig is one.  That also powers
the rotor and laptop.  Those things are always on and the noise isnt always
there.

It stayed on with everything off, so must be outside of my house. It went
away shortly after I did this test.  It doesn't seem to be on at night, so
wonder what might run during the day with this type of cycling that wouldn't
be running at night.
